A aplicação de técnicas de workflows na área de computação científica é bastante explorada para a condução de experimentos e construção de modelos in silico. Ao analisarmos alguns desafios enfrentados por uma aplicação científica na área de geociências, percebemos que workflows podem ser usados para representar os modelos gerados na aplicação e facilitar o desenvolvimento de funcionalidades que supram as necessidades identificadas. A maioria dos trabalhos e ferramentas na área de workflows científicos, porém, são voltados para uso em ambientes de computação distribuída, como serviços web e computação em grade, sendo de difícil uso ou integração dentro de aplicações científicas mais simples. Nesta dissertação, discutimos como viabilizar a composição e representação de workflows dentro de uma aplicação científica existente. Descrevemos uma arquitetura conceitual de motor de workflows voltado para o uso dentro de uma aplicação stand-alone. Descrevemos também um modelo de implantação em uma aplicação C plus plus usando redes de Petri para modelar um workflow e funções C plus plus para representar as tarefas. Como prova de conceito, implantamos esse modelo de workflows em uma aplicação existente e analisamos o impacto do seu uso na aplicação.
The use of workflow techniques in scientific computing is widely adopted in the execution of experiments and building in silico models. By analysing some challenges faced by a scientific application in the geosciences domain, we noticed that workflows could be used to represent the geological models created using the application so as to ease the development of features to meet those challenges. Most works and tools on the scientific workflows domain, however, are designed for use in distributed computing contexts like web services and grid computing, which makes them unsuitable for integration or use within simpler scientific applications. In this dissertation, we discuss how to make viable the composition and representation of workflows within an existing scientific application. We describe a conceptual architecture of a workflow engine designed to be used within a stand-alone application. We also describe an implementation model of this architecture in a C plus plus application using Petri nets to model a workflow and C plus plus functions to represent tasks. As proof of concept, we implement this workflow model in an existing application and studied its impact on the application.

Abstract:
An attempt was made to investigate two aspects of the learning and teaching context. One deals with how the sets of beliefs or expectations pupils hold about some phenomena affect the sense they make of experiences given to them in science classes. The other deals with the potential effect of the inevitable use of "scientific" and "everyday" language by both teachers and pupils in instruction. A sample of thirty Portuguese students from grade five to grade nine (10-15 years old) were given laboratory experiences and "parallel" everyday phenomena to discuss individually with the interviewer and then were invited to describe orally what and why things happened. The fundamental conceptions that students hold, the changes of these conceptions with students' age, as well as their consistency in different contexts and in similar tasks were identified in this experiment. The results suggested that these students, although having been exposed to formal teaching, still retain and use intuitive notions to think: about experiences in science lessons. The focus of the second experiment was to investigate how teachers' own perceptions may influence the development of pupils' ideas. It was carried out by observing seven teachers during ordinary classroom activities, to discover the relative contributions of 'scientific' and 'everyday' meaning in the language they used. Common features in teachers' and students' conceptualizations of "heat", "temperature" and "energy" were identified. Two main questions were discussed: i) what are the implications of the semantic variability in the disparate linguistic references for science education? ii) how to bridge the gap between teachers' and students' understandings, i.e., what connections can be made between what teachers and students talk about and perceive from discourse in the classroom? The results of this study seemed to reinforce the idea that it is impossible to keep external, everyday, informal culture out of the science classroom.

Abstract:
This thesis can be described in various terms. It is a translation of Vygotsky's theory of scientific concepts, in reality a theory of development, into a theory of mathematics teaching and learning. It is a theorisation, and development, of connectionist pedagogy in mathematics (a relatively underdeveloped, yet exemplary, amalgam of various reform/progressive /meaningful approaches to teaching). And, it is an investigation of the elements and processes involved in mathematical concept development, and the mediating role which classroom tasks can play. Alongside this, these understandings are embedded within a wider understanding of society, schooling, mathematics and mathematics teaching which help explain the current dominant practice in the classroom, and in doing so add to the understandings already described. In sum, the thesis therefore represents the beginnings of a systematic Marxist perspective of mathematics education which can cohere analysis at the multiple levels of society, schooling, classroom teaching and learning, and individual concept development. As such it is also, as should always be the case with Marxist perspectives, a guide to action for critical mathematics educators. The thesis begins with context, motivation and strategy, an overview of relevant literature, and an explanation of the methodology and methods used within. The relationship between Vygotsky's theory of concept development and connectionist teaching is then outlined and developed. The wider societal perspective follows, with an emphasis on generalised commodity production as the key shaper of schools and classrooms. Both of these themes are then developed in relation to the example of vocational mathematics, both providing evidence of the existence and nature of scientific activity and concepts, and connecting their absence to the obstacles related in the previous section. The thesis continues by exploring a pedagogical development based on Vygotsky's theory, looking at the explicit problematising of generalisation, and analysing classroom dialogue in relation to this. In the other direction, a theoretical development is then made, following an illustration of the pedagogical and theoretical framework through the development of a particular concept. Finally, conclusions are drawn and future work outlined.

Abstract:

This study incorporated an intervention that combined discussion and sentence writing to promote vocabulary development. Fourth grade students were assigned to either an intervention or control condition. Teachers in the intervention classrooms used a word learning protocol that was designed to provide students with student-friendly definitions and a minimum of 15 exposures to each target word through both receptive and expressive tasks. These tasks called upon students to begin to make connections between spontaneous and scientific concepts to support their word learning. Teachers in control classrooms followed instructional routines as specified in their school’s reading series. Multiple choice assessments from the district adopted reading series for vocabulary and comprehension along with a researcher-developed sentence writing task were used to measure growth in word knowledge. On the multiple choice vocabulary assessment, the intervention group outperformed the control group on one of the three weekly assessments from the reading series. There were no differences in comprehension scores on weekly reading tests across groups. On the sentence writing task, results indicated that the intervention group outperformed the control group with the intervention group showing a statistically significant difference in the rate at which they learned words.

Our basic assumption for this work is that the abilities to appraise and to categorize are closely related, leading us to the conclusion that they are part of a single process: that of knowledge organization. In this paper, we will discuss specifically some topics involving knowledge organization as far as concept formation is concerned, searching to understand its nature. For this purpose, we have used as theoretical background the works on concept formation by Vygotsky ([1934] 2000) and Nelson (1998; 1986). We believe that Nelsonâs views on young children cognitive processing, centered on the action context and on the childrenâs daily experiences can provide a more significant contribution for an extended vision of the nature of the process of concept formation than the ideas presented by Vygotsky who, in spite of stressing the importance of the context in concept formation, carried out his experiments based on artificial concepts. To check if the concepts become more abstract as time goes by or if they show to be limited to the individualâs context, connected to their memory (thus contextualized), we carry out a study with Elementary, Junior High and High School students as subjects, whose main purpose was to understand the nature of the participantsâ concepts. The students were asked to define the terms âplantâ and âanimalâ and took part in two classification activities using a set of cards, adapted from Panofsky, John-Steiner and Blackwell (1996), which consisted of twenty and one (21) pictures (07 belonging to the âplantâ category and 14 to the âanimalâ category). From the analysis of the definitions obtained and of the justifications for grouping the items into categories, we could observe that there is not a single, exclusive base for the participantsâ conceptualizations, that is, none of the categories has shown to be predominant. On the contrary, the category concepts are formed from internalized pieces of information about the world, no matter if these pieces of information are of a daily or of a more formal nature.
Neste trabalho partimos da premissa de que as habilidades de conceituar e de categorizar estÃo intimamente relacionadas, levando-nos a concluir que elas fazem parte de um Ãnico processo: o de organizaÃÃo do conhecimento. Especificamente, abordaremos questÃes concernentes à organizaÃÃo do conhecimento no tocante à formaÃÃo de conceitos buscando compreender a sua natureza. Para isso, utilizamos como base teÃrica os trabalhos sobre formaÃÃo de conceitos de Vygotsky ([1934] 2000) e de Nelson (1998; 1986). Defendemos que a proposta de Nelson sobre o processamento cognitivo de crianÃas jovens, centrada no contexto de aÃÃo, nas experiÃncias cotidianas das crianÃas, pode contribuir para uma visÃo mais ampliada da natureza do processo de formaÃÃo de conceitos que a visÃo apresentada por Vygotsky que, mesmo defendendo a importÃncia do contexto na formaÃÃo dos conceitos, realizou seus experimentos utilizando-se de conceitos artificiais. Para verificarmos se os conceitos com o passar do tempo vÃo se tornando mais abstratos ou se, ainda, mostram-se, presos ao contexto do indivÃduo, ligados à memÃria de eventos (contextualizado), realizamos uma pesquisa com alunos do Ensino Fundamental e do Ensino MÃdio com o objetivo de compreender a natureza dos conceitos dos participantes. A tarefa experimental consistiu de uma atividade de definiÃÃo para os termos planta e animal e duas atividades de classificaÃÃo usando um conjunto de cartÃes, adaptado de Panofsky, John-Steiner e Blackwell (1996) que constou de vinte e uma (21) figuras (07 da categoria plantas e 14 da categoria animais). AtravÃs da anÃlise das definiÃÃes e justificativas para os agrupamentos de itens em categorias, pudemos verificar que nÃo hà uma Ãnica e exclusiva base para as conceitualizaÃÃes dos participantes, ou seja, nÃo hà predominÃncia de uma ou de outra categoria, e sim que seus conceitos sÃo formados a partir de pedaÃos de informaÃÃes internalizadas sobre o mundo quer sejam cotidianas quer sejam mais formais.

Abstract:
Visitors use and understanding of interactive exhibits and their learning of scientific concepts was investigated by three studies. The first study categorised visitors' use of a sound exhibit and found that 49% successfully used the exhibit. Understanding was described with a knowledge hierarchy and learning was measured using a pre-test and post-test. Findings indicated that many visitors had prior knowledge of the relevant concepts and 50% of visitors learnt a concept from the exhibit. The second study investigated young children's understanding and interaction with the Mitey Quarry, a cooperative exhibit of four elements, conveyor, elevator, auger and sorter, which were used to move balls around the exhibit. Findings indicated that children's activities and their level of understanding varied for each element, though higher levels were achieved with elements that were easily observable. The children's activities began with observation, and then vacillated between manipulation, operation and control of an element. The third study identified the educational objectives of a physical fitness exhibit, Let's Get Physical, and their achievement by high school students. Findings indicated that the instructional sequence integrated cognitive and affective objectives, and although 42% of students stated their intentions to begin new exercise activities in response to the exhibit message "to be active everyday", after two weeks, these intentions had not been enacted. The research has contributed to improved exhibit design by demonstrating the value of knowledge, activity and affective hierarchies in identifying exhibit objectives and providing a means for evaluation. Hierarchies are an effective way to describe and measure the visitors' use and understanding of interactive exhibits and learning from them.

Abstract:
´Scientific revolution´, as a concept, is both ´philosophically general´ and ´historically unique´. Both dual-sense of the term alludes to the occurrence of great changes in science. The former defines the changes in science as a continual process while the latter designate them, particularly, as the ´upheaval´ which took place during the early modern period. This research aims to demonstrate how the historicists´ critique of the justification of the traditional claims of science on the basis of the scientific processes and norms of the 16th and 17th centuries, illustrates the historical/local determinacy of the science claims. It argues that their identification of the contextual and historical character of scientific processes warrants a reconsideration of our notion of the universality of science. It affirms that the universality of science has to be sought in the role of such sources like scientific instruments, practical training and the acquisition of methodological routines
"Revolución científica", como concepto, se refiere a la vez a algo «filosóficamente general» e « históricamente único". Ambos sentidos del término aluden a la ocurrencia de grandes cambios en la ciencia. El primero define los cambios en la ciencia como un proceso continuo, mientras que el último los designa, en particular, como la "transformación", que tuvo lugar durante la Edad Moderna. Esta investigación tiene como objetivo demostrar cómo la crítica de los historicistas a la justificación de las características tradicionales de la ciencia sobre la base de los procesos y normas científicos de los siglos XVI y XVII, ilustra la determinación histórica y local de los atributos de la ciencia. Se argumenta que la identificación del carácter contextual e histórico de los procesos científicos justifica una reconsideración de nuestra noción de la universalidad de la ciencia. Se afirma que la universalidad de la ciencia se ha de buscar en el papel de tales fuentes como instrumentos científicos, la formación práctica y la adquisición de rutinas metodológicas

Abstract:
Initial teacher education is an area of weakness within the Chilean education system. Yet it is highlighted as a crucial aspect of educational success. Success in educational improvement depends mainly on the teachers (because they enact a reform by putting it into practice), and teacher thinking is likely to influence teacher decision-making. How teacher conceptions and practice change, and how to facilitate this change, was the focus of this study. It explored to what extent peer assessment could facilitate change in pre-service science teachers’ conceptions and practices regarding conceptual explanations in science teaching.In a quasi-experimental design, a ten-session peer assessment intervention was carried out with thirty seven pre-service science teachers in three Chilean universities, each with an experimental and control group. The intervention sought to develop changes in teachers’ conceptions about the quality of explanations and in their skill of explaining scientific concepts. Teachers' thoughts were obtained through a peer assessment questionnaire, feedback sessions, focus groups and interviews. The quality of their explanations was measured at pre, post and follow-up in their eventual first job via video-recorded microteaching episodes using observational analysis. Inter-rater reliability was calculated on 5% of all qualitative data and all the videos were rated by two researchers in a blind process. Qualitative analysis indicated how teachers transformed their conceptions about the quality of explanations from general pedagogical knowledge into pedagogical content knowledge. A quantitative instrument was created to evaluate student teachers’ explanations in practice. Its reliability enables the assessment the skill of explaining based on ten elements (Cronbach’s alpha=.77). Results showed pre-service teachers significantly improved their explanations of scientific concepts in some practical aspects, although not all of them were transferred into real teaching contexts. The changes in student teachers’ conceptions and practice were analysed to indicate how the process occurred, to what extent peer assessment had a role on it, and which elements facilitated or made difficult the transference of the skill of explaining into real teaching. These results indicated that peer assessment can play a noteworthy role in teacher education to develop skills. There are implications for policy and practice in this study, not only for teacher education but also for in-service teacher professional development, not only for Chile but also for other countries.

A large percentage of South African learners held inadequate or alternative conceptions that might hinder them from developing a valid understanding of various scientific concepts and generalizations. This study explored the conceptions of Senior Phase learners on magnetism, chemical change of substances and the environment. More explicitly, the study attempted to investigate the influence of the learners" age, language and gender issues on their understanding of these scientific concepts. The study is underpinned by socio-cultural constructivism as espoused by Vygotsky (1978). The research sample comprised 250 Senior Phase learners (grades eight and nine) from secondary schools in the Metro Central District in the Western Cape. The study used the following six research instruments for data collection: Science Achievement Test (SAT), Context Test, Cloze Test, Picture Test, Science Vocabulary Test and an interview schedule. The tests were administered to all the participants while the interview was conducted with six participants.This study was a descriptive research of a survey type and data was collected and analyzed using both quantitative and qualitative methods.The data collected was analyzed quantitatively using the Statistical Package for Sciences (SPSS) in order to obtain descriptive statistics that were used to explore the conceptions of senior phase learners in magnetism, chemical change substances and the environment in the Metro Central district while data from the tape recorder and notes taken during the interview, were analyzed qualitatively.

Abstract:
This thesis confronts a fundamental shortcoming in cognitive science research: a failure to be explicit about the theory of concepts underlying cognitive science research and a resulting failure to justify that theory philosophically or otherwise. It demonstrates how most contemporary debates over theories of concepts divide over whether concepts are best understood as (mental) representations or as non-representational abilities. It concludes that there can be no single correct ontology, and that both perspectives are logically necessary. It details three critical distinctions that are frequently neglected: between concepts as we possess and employ them non-reflectively, and concepts as we reflect upon them; between the private (subjective) and public (inter-subjective) aspects of concepts; and between concepts as approached from a realist versus anti-realist perspective. Metaphysical starting points fundamentally shape conclusions. The main contribution of this thesis is a pragmatic, meticulously detailed, and distinctive account of concepts in terms of their essential nature, core properties, and context of application. This is done within the framework of Peter Gärdenfors' conceptual spaces theory of concepts, which is offered as a bridging account, best able to tie existing theories together into one framework. A set of extensions to conceptual spaces theory, called the unified conceptual space theory, are offered as a means of pushing Gärdenfors' theory in a more algorithmically amenable and empirically testable direction. The unified conceptual space theory describes how all of an agent's many different conceptual spaces, as described by Gärdenfors, are mapped together into one unified space of spaces, and how an analogous process happens at the societal level. The unified conceptual space theory is put to work offering a distinctive account of the co-emergence of concepts and experience out of a circularly causal process. Finally, an experimental application of the theory is presented, in the form of a simple computer program.

Abstract:
Nesta pesquisa investigamos em um grupo de estudantes do curso de Química a construção do raciocínio através da argumentação dos alunos, suas estruturas cognitivas e articulações na resolução de problemas de uma atividade prática de Química Analítica Qualitativa, mais especificamente pesquisa de cátions e ânions numa marcha analítica. Após a transcrição das falas registradas em vídeo, analisamos a argumentação e o gênero do discurso dos estudantes e verificamos a importância da estruturação do pensamento reversível (ou ainda chamado de mobilidade retroativa) para a formação do Químico, bem como um raciocínio lógico-formal. Conseqüentemente, procuramos avaliar as razões pelas quais os alunos não estabelecem uma aproximação entre a teoria e a experimentação, além da deficiência na argumentação a respeito dos conceitos teóricos e os fenômenos ocorridos nesta prática de laboratório, o que demonstra pouca ou nenhuma compreensão destes conceitos. Os resultados obtidos apontam que as atividades práticas em Química Analítica Qualitativa revelam-se fundamentais para que o aluno possa apreciar a lógica envolvida na descoberta do conhecimento pela interação com o fenômeno e não meramente por uma repetição mecânica de procedimentos experimentais, como normalmente se verifica. A postura adotada pelo professor em muito contribuirá para o sucesso ou não desse objetivo, pois deve haver na sala de aula uma interação dialética e dialógica em toda a prática didática e experimental da disciplina.
In the present research it was investigated the formation of the thought throughout the students argumentations in a chemistry course, its cognitive structures and articulations in solving problems in a practical activity of qualitative analytical chemistry, more specifically, the study of cations and anions in an analytic march. After the video talk transcription, it was analyzed the argumentation and the sort of the speech and it was verified the importance of the reversible thought structuring (also called retroactive mobility) for a Chemist formation, as well as a formal logical reasoning. Consequently, we looked forward to evaluate the rezones why students can not link the theory and the experimentation, more over the deficiency in argumentation about the theoretical concepts and the phenomenal shown in the laboratory practice, what shows few or no comprehension of those concepts. The results reveal that it is fundamental the use of practical activities in Qualitative Analytical Chemistry. With this experience the students can appreciate the logic involved in the discovery of the knowledge through the interaction with the phenomenon and not only for a mechanical repetition of experimental procedures, as the daily routine shows. The adopted posture for the teacher will deeply contribute for the success or not of this goal, therefore, it must have in class a dialectic interaction and dialogic in all didactic practice and experimental of the subject.

O presente trabalho consiste em uma investiga??o acerca das concep??es de estudantes sobre o que ? um inseto. Partiu-se do pressuposto de que os alunos expressam concep??es err?neas no momento de identificar os representantes do t?xon Insecta e que isso ? consequ?ncia das experi?ncias do cotidiano e de erros conceituais oriundos da forma??o escolar incorreta. Os objetivos deste trabalho foram investigar sobre concep??es alternativas acerca dos insetos com alunos do ensino fundamental II e propor situa??es para promo??o de uma aprendizagem mais ativa. Os dados para analise foram coletados em tr?s turmas de escolas diferentes: uma escola em Nova Parnamirim, da rede privada, e duas da rede p?blica municipal de ensino: uma do munic?pio de Natal/RN e a outra do munic?pio de Parnamirim/RN. Utilizou-se como instrumento um question?rio aplicado em duas fases. Na primeira etapa foram feitas tr?s quest?es abertas e duas fechadas. Na segunda, aplicaram-se mais tr?s quest?es. Nesta oportunidade foram apresentados aos alunos uma lista com imagens de insetos e animais considerados n?o insetos. Os resultados dos question?rios mostraram que os alunos apresentaram na sua maioria, 62%, sentimentos negativos sobre os insetos, expressos por palavras depreciativas, entre elas: nojentos, feios, asquerosos, perigosos, sendo estes mais da metade dos alunos da amostra. Sentimentos positivos representaram 20%: fazem bem ao homem, Deus criou, s?o bons, s?o bonitos, e 18% apresentaram neutralidade nessas categorias. Outro resultado apresentado foi que 82% generalizaram os animais artr?podes como sendo insetos. Como forma de resolver problemas relacionados as concep??es uma unidade did?tica foi aplicada em uma das escolas envolvidas na pesquisa, validando assim um instrumento pedag?gico que incluiu atividade l?dica constitu?da de um jogo de tabuleiro proporcionador de uma viv?ncia de aprendizagem focada em conceitos cient?ficos sobre os insetos f?ceis de serem apreendidos

Abstract:
As políticas educacionais da atualidade estão voltadas para a qualidade do ensino. Diante da crise que repercutiu o movimento antigramaticalista nas aulas de língua portuguesa, das discussões sobre o despreparo de muitos professores para exercer a docência e cientes de que o ensino da língua materna apresenta sérios problemas, pareceu-nos interessante investigar as principais dificuldades que, no entender dos professores, interferem no ensino e aprendizagem da Língua portuguesa. O objetivo deste trabalho é verificar as apreciações docentes acerca das dificuldades no ensino e aprendizagem da gramática. Ao verificar as possíveis causas do insucesso do trabalho pedagógico no ensino e aprendizagem da gramática, surgem questionamentos como: qual seria a formação `ideal para o professor de língua portuguesa? O que falta na formação inicial desses professores, conteúdo ou didática? A crise no ensino da Língua Portuguesa trouxe dificuldades para a prática docente? Assim considerando, realizamos uma pesquisa com dezessete professores da rede municipal de ensino fundamental de uma cidade do interior de São Paulo. Os dados foram obtidos por meio de um questionário de sete questões. Para análise do corpus da pesquisa, nos baseamos nos construtos de Análise de Conteúdo de Bardin, metodologia que se apresenta como um conjunto de técnicas de análise das comunicações que utiliza procedimentos sistemáticos e objetivos de descrição do conteúdo das mensagens. As regularidades temáticas que emergiram no discurso docente nos permitiram associar as principais dificuldades do professor com a falta de domínio dos conteúdos gramaticais da Língua Portuguesa. No entanto, conhecer a gramática da língua é fundamental para que o professor saiba planejar sua prática. Assim sendo, esse resultado sinaliza a necessidade de tornar a teoria gramatical um conhecimento útil que corrobore não só o domínio da norma padrão, mas também a postura confiante do professor diante das dificuldades no processo de ensino e aprendizagem da língua portuguesa.
Nowadays the educational policies are focused on teaching quality. Toward the crises that reverberated the anti-grammatical movement in the Portuguese language classes, the discussions about the lack of preparation of many teachers for teaching, and as we are conscious that the native language teaching presents many problems, it seemed to us interesting to investigate the main difficulties that, according to the teachers, interfere with the teaching and learning of Portuguese language. The aim of this research is to verify the teachers appreciations about the difficulties in the grammar teaching and learning. As we verify the possible causes of the unsuccessfulness in the pedagogical work involving the grammar teaching and learning, comes up questions like: what is the Portuguese teachers `ideal education? What is missing in the initial teachers education, content or didactics? The crises in the Portuguese language teaching brought difficulties for the teaching practice? Therefore, we performed a research with seventeen teachers of the municipal network of elementary schools in a city in the interior of São Paulo. The data were obtained through a questionnaire made up of seven questions. For the corpus analysis we were based on the Content Analysis by Bardin, a methodology that presents itself like a set of techniques of communication analyses which uses systematic procedures and objectives of contents message description. The regularity of themes that emerged from the teachers discourse allows us to associate the teachers main difficulties with the lack of mastery on the grammatical contents of Portuguese language. Knowing the language grammar, nevertheless, is essential for the teacher when he (she) is planning his (her) practice. So, this result indicates the necessity of making the grammar theory a useful knowledge which corroborates not only the mastery of the standard rules, but also the teachers confident attitude towards the difficulties in the teaching and learning process of Portuguese language.

Abstract:
No livro The Insect Societies, Wilson propôs categorias de socialidade que foram consideradas uma unificação histórica da terminologia no estudo do comportamento social. Desde então, muitos novos padrões comportamentais foram descritos, mas não podiam ser encaixados em nenhuma das categorias disponíveis, prejudicando o consenso em torno dessa classificação bem estabelecida. Novas classificações gerais tentaram contornar as limitações mostradas pela categorização de Wilson, mas com pouco sucesso. Entre as proposições, algumas mantêm a forma de categorização discreta usando características consideradas importantes pelos autores que as propuseram; outros avançam em um modelo quantitativo de caracterização da socialidade. A análise de Carnap sobre os tipos de conceitos em ciência pode nos ajudar a avançar nesta discussão. Sua distinção entre conceitos qualitativos (classificatórios e comparativos) e conceitos quantitativos é usada aqui como base epistemológica para analisar o desenvolvimento das mudanças conceituais e classificações de socialidade propostas. A abordagem de Carnap reforça a proposta de superar a dicotomia entre espécies sociais e sociais a favor de um modelo de gradientes de socialidade. Concluímos que uma nova métrica de socialidade deve ser construída, usando características que não são arbitrárias, mas sim evolutivamente significativas e que permita a comparação entre o comportamento social de todas as espécies. Nesse sentido, a análise de redes sociais tem sido usada para descrever a estrutura de diferentes sociedades, características da estrutura das redes são comparáveis entre grupos e espécies. Aranhas sociais se constituem como um ótimo objeto de estudo, pois apresentam diferentes níveis de socialidade em diferentes níveis taxonômicos. Nós, portanto, desenvolvemos uma abordagem de redes sociais para quantificar a socialidade em colônias de Anelosimus eximius e descrever sua estrutura. Somado a isso, e considerando que a divisão do trabalho é uma característica importante das espécies eussociais, nós testamos se os indivíduos nas colônias se especializam em tarefas e se organizam em grupos em diferentes contextos sociais. Além disso, avaliamos quais os efeitos do tamanho de grupo nesta organização social. Indivíduos de A. eximius apresentam uma organização em grupos nos diferentes contextos sociais, e as colônias apresentam uma baixa, porém significativa, taxa de especialização em tarefas. Os grupos variam entre contextos, mas são frequentemente similares em contextos ativos. Em colônias menores, os indivíduos não apresentam grupos consistentes, todos os individuos parecem necessários para as tarefas. Complexidade social definida como especialização e formação de grupos dentro da colônia parece ser uma métrica útil de socialidade, permitindo a comparação de uma gama de espécies. O tamanho dos grupos tem que ser levado em conta, porque indivíduos aparentam ser sensíveis às necessidades da colônia
In the book The Insect Societies, Wilson proposed categories of sociality that were considered a landmark unification of terminology in the study of social behavior. Since then, many new behavioral patterns were described, but they could not be fitted in any of the available categories, undermining the consensus around that wellestablished classification. New general classifications tried to circumvent the limitations shown by Wilsons categorization, but with little success. Among the propositions, some maintain the form of discrete categorization using features considered important by the authors who proposed them; others advance a quantitative model of characterization of sociality. Carnap\'s analysis of types of concepts can help moving forward in this discussion. His distinction between qualitative concepts (classificatory and comparative) and quantitative concepts is used here as an epistemological basis for analyzing the development of the proposed conceptual changes and classifications of sociality. Carnaps approach reinforces the proposal of overcoming the dichotomy between eusocial and social species in favor of a model of sociality gradients. We conclude that a new metric of sociality should be built, using characteristics that are non-arbitrary, evolutionarily meaningful, and amenable to comparing social behavior between all species. In this context, social network analysis is currently used as a means to describe social structures in animal systems, and the network structure characteristics can be compared across groups of different composition and species. Social spiders are good models to study social behavior because they present different levels of sociality in different taxonomic levels. We develop a social network approach to quantifying sociality in Anelosimus eximius colonies and describe its structure. In addition, since division of labor is an important feature of eusociality, we evaluated individual specialization in colony tasks and tested for the existence of groups of individuals through different social contexts. We also evaluated the effects of colony size on such organization. A. eximius present a organization in groups in different social contexts, and colonies exhibit a low, but significant, specialization rate in particular tasks. Group composition among spiders was flexible but frequently similar in active tasks. Individuals in smaller colonies did not form consistent groups; all individuals seem necessary to perform the tasks. The evaluation of social complexity in terms of specialization and group organization seems to be a useful metric, allowing the comparison of a wide range of species. Colony size should be an important qualifier of this metric, since individual behavior appears sensitive to colony needs

Este trabalho investigou como as sequências de atividades mediadas por recursos computacionais contribuem para o processo de formação dos conceitos científicos de calor, trabalho e entropia entre estudantes licenciandos em Química. Essa pesquisa atravessa diversos campos do conhecimento como educação, psicologia e computação, visando a estruturar e a analisar diferentes estratégias pedagógicas mediadas por tecnologias computacionais tais como a animação interativa, a modelagem e a simulação computacional. A fundamentação teórica do eixo didático e pedagógico encontra-se apoiada nos estudos de Zabala e Galperin, enquanto que o eixo psicológico busca inspiração na Teoria Histórico- Cultural de Vigotski e em seus estudos experimentais do desenvolvimento de conceitos científicos. Para responder esse problema de pesquisa, foi utilizado o método de investigação de estudo de casos, sob o enfoque explanatório. Os casos ou unidades de análise consistiram em dois grupos de estudantes do curso de licenciatura em Química do Instituto Federal Fluminense, RJ, Brasil, cujas ideias conceituais foram acompanhadas durante as atividades computacionais, em termos de emprego dos signos e sua aplicação não mecânica, reflexão acerca das propriedades gerais e essenciais dos objetos e capacidade de abstração. Com isso, foi proposto um desdobramento das ideias de Zabala e Galperin relativas às qualidades desejáveis nas sequências de atividades mediadas por recursos computacionais, bem como descrito um modelo teórico para a dinâmica do processo de formação dos conceitos científicos durante as respectivas sequências de atividades.
This study aimed to investigate how the sequences of activities mediated by computational resources contribute to the formation process of scientific concepts of heat, work and entropy among chemistry undergraduate students. Our research goes through several fields of knowledge such as education, psychology and computing, in order to structure and analyze different teaching strategies mediated by educational technologies such as interactive animation, modeling and computer simulation. The theoretical basis for didactics and pedagogy is supported by the Zabala and Galperin studies, while the psychological framework is inspired in the Historical-cultural Theory of Vygotsky and his experimental studies on the development of scientific concepts. To answer our research problem, the case study method was used under an explanatory focus. Our cases or units of analysis consisted of two students groups from the graduate program of chemistry of Fluminense Federal Institute, RJ, Brazil, whose conceptual ideas were followed during computational activities, in terms of signs employment and its non mechanical application, reflection on the general and essential properties of objects and the capacity for abstraction. As a result, we were able to propose a deployment of Zabala and Galperin ideas focused on the qualities desirable in the sequences of activities mediated by computational resources and also describe a theoretical model for the dynamic formation process of the scientific concepts during the respective sequence of activities.

At school today, teachers need not only to teach but also to be creative using educational resources to support teaching and especially to motivate students in the knowledge construction. The use of these resources must be appropriate with the purpose to help students learn. The report of experiences helps school teachers through alternative methods of education to bring together students from Science. This study aimed to check the student learning based on their spontaneous conceptions and help them to build the scientific knowledge about the theme proposed throughout the learning process. The study was carried out using questions and experimental activities. The topic chosen was digestion. Eight practical activities were done in order to diagnose the pre-existing knowledge of the students, which was then complemented with the scientific knowledge taught by the teacher aiming to motivate students to develop a taste for Science. This work was carried out with students from 6th to 9th grade of a public municipal school in Santa Maria, RS. The experiments performed at school were about the biochemical processes of digestion. All classes presented good performance in the practical classes, where a significant learning actually occurred according to the topic proposed. Our findings show that there was student enrichment in relation to the concepts taught, achieving a good understanding of the theme, i.e., the process of digestion. Although the students have demonstrated their understanding of the subject proposed, it is important to point out that they presented some difficulties to build the knowledge to new learning situations.
Na escola de hoje, o professor, além de ensinar, precisa ter criatividade, necessitando também utilizar de recursos didáticos de apoio pedagógico, principalmente no sentido de motivar os alunos na construção de conhecimento. O uso desses recursos deve ser apropriado com finalidade de que o aluno aprenda. O relato das experiências visa a ajudar os professores das escolas por meio de métodos alternativos para o ensino, aproximando os alunos da Ciência. O objetivo desse estudo foi verificar o aprendizado dos alunos baseado nas suas concepções espontâneas e ajudá-los a construir o conhecimento científico sobre o tema proposto ao longo da escolaridade. A pesquisa foi realizada por meio de questionamentos e atividades experimentais. O tema escolhido foi digestão. Foram realizadas oito atividades práticas com a finalidade de diagnosticar os conhecimentos préexistentes dos alunos que então foram complementados com o conhecimento científico transmitido pelo professor objetivando estimular o aluno a desenvolver o gosto pela Ciência. Este trabalho foi realizado no 6º ao 9º ano de Ensino Fundamental de uma Escola Pública Municipal de Santa Maria, RS. Os experimentos realizados na escola foram os processos bioquímicos da digestão. Quanto aos conhecimentos das turmas, todas tiveram bom aproveitamento nas práticas, em que verificamos que realmente ocorreu aprendizagem significativa de acordo com o tema abordado. Em função dos resultados desse trabalho, é possível afirmar que houve enriquecimento dos alunos em relação às concepções, conseguindo compreender bem o processo da digestão. Embora os alunos tenham demonstrado sua compreensão de acordo com o tema estudado, é importante salientar que eles mantêm algumas dificuldades de construir o conhecimento, para novas situações de aprendizagem.

Abstract:
Bacterial resistance to antibiotics threatens modern healthcare on a global scale. Several actors in society, including the general public, must become more involved if this development is to be countered. The conveyance of relevant information provided through education and media reports is therefore of high concern. Antibiotic resistance evolves through the mechanisms of natural selection; in this way, a sound understanding of these mechanisms underlies explanations of causes and the development of effective risk-reduction measures. In addition to natural selection functioning as an explanatory framework to antibiotic resistance, bacterial resistance as a context seems to possess a number of qualities that make it suitable for teaching natural selection – a subject that has been proven notoriously hard to teach and learn. A recently suggested approach for learning natural selection involves so-called threshold concepts, which encompass abstract and integrative ideas. The threshold concepts associated with natural selection include, among others, the notions of randomness as well as vast spatial and temporal scales. Illustrating complex relationships between concepts on different levels of organization is one, of several, areas where visualizations are efficient. Given the often-imperceptible nature of threshold concepts as well as the fact that natural selection processes occur on different organizational levels, visual accounts of natural selection have many potential benefits for learning. Against this background, the present dissertation explores information conveyed to the public regarding antibiotic resistance and natural selection, as well as investigates how these topics are presented together, by scrutinizing media including news reports, websites, educational textbooks and online videos. The principal method employed in the media studies was content analysis, which was complemented with various other analytical procedures. Moreover, a classroom study was performed, in which novice pupils worked with a series of animations explaining the evolution of antibiotic resistance. Data from individual written assignments, group questions and video-recorded discussions were collected and analyzed to empirically explore the potential of antibiotic resistance as a context for learning about evolution through natural selection. Among the findings are that certain information, that is crucial for the public to know, about antibiotic resistance was conveyed to a low extent through wide-reaching news reporting. Moreover, explanations based on natural selection were rarely included in accounts of antibiotic resistance in any of the examined media. Thus, it is highly likely that a large proportion of the population is never exposed to explanations for resistance development during education or through newspapers. Furthermore, the few examples that were encountered in newspapers or textbooks were hardly ever visualized, but presented only in textual form. With regard to videos purporting to explain natural selection, it was found that a majority lacked accounts of central key concepts. Additionally, explanations of how variation originates on the DNA-level were especially scarce. These and other findings coming from the content analyses are discussed through the lens of scientific literacy and could be used to inform and strengthen teaching and scientific curricula with regards to both antibiotic resistance and evolution. Furthermore, several factors of interest for using antibiotic resistance in the teaching of evolution were identified from the classroom study. These involve, among others, how learners’ perception of threshold concepts such as randomness and levels of organization in space and time are affected by the bacterial context

Abstract:
La présente étude s’intéresse particulièrement aux différents concepts physiques relatifs à l’électricité et à l’enseignement de ces concepts au collège en Syrie. Ces concepts étant souvent difficiles à comprendre par les élèves, et à enseigner par les enseignants, ils sont introduits formellement dès la classe de 5ème = CM2 au collège en Syrie. L’objectif de cette recherche a été, dans un premier temps, l’étude des différentes modes de présentation des notions de l’électricité dans le savoir de référence. Pour ce faire, nous avons choisi trois ouvrages universitaires de l’électricité. Puis nous sommes partie regarder les choix pris par les institutions pour enseigner ces notions ; nous précisons que nous intéressons aux choix des contenus et également des méthodes dans le programme de l’enseignement pré-universitaire en Syrie. Par la suite nous sommes parties regarder également ces derniers choix dans les manuels scolaires des classes de 5ème, 6ème, 8ème, 9ème en Syrie qui sont équivalentes à CM2, 6ème, 4ème et 3ème en France. Dans un deuxième temps, l’objectif de cette recherche fut de savoir une idée sur le point de vu des enseignants comme acteurs principaux de cette rénovation. Pour cela, un échantillon de 30 enseignants de physique chimie au niveau collège en Syrie, ont répondu à un questionnaire écrit portant sur l’enseignement des différentes notions de l’électricité. Le but est d’étudier les conceptions et les représentations sur l’électricité chez leurs élèves et les difficultés rencontrée en enseignant tel notions, en particulier à l’égard des différents concepts didactiques recommandés pour enseigner ces notions au collège. Enfin, notre étude permet de constater que malgré le grand appui dans le programme et les manuels scolaire sur l’importance d’aborder les notions électricité avec une méthode expérimentale, le recours expérimentale et analogique dans l’enseignement de collège en Syrie reste minoré. Afin de connaître les conceptions pédagogiques et épistémologiques des enseignants sur leur manière d’aborder l’enseignement de l’électricité, nous avons construit les données au moyen d’une enquête par questionnaire auprès de 30 enseignants. Les réponses à ce questionnaire ont été analysées suivant deux perspectives, pédagogique et didactique. Pour l’analyse à caractère pédagogique, une grille a été construite autour des modes de représentation privilégiés par les maîtres et autour des rôles respectivement réservés au maître et à l’élève. En parallèle, nous avons vérifié leur niveau maîtrise des différents concepts en didactique des sciences. Pour introduire les concepts de l’électricité, les enseignants affirment qu’ils laissent une large place aux activités expérimentales quand les circonstances sont pertinentes. L’analyse effectuée sur les manuels scolaires a été faite à l’aide d’une grille d’analyse, les résultats d’analyse de ces manuels montrent que les propositions de mise en œuvre d’une démarche expérimentale avec un recours modélisé restent minorées dans ces derniers. De plus, il ressort de l’étude du questionnaire destiné aux enseignants que ce processus expérimentale en lien avec une démarche d’investigation en électricité a du mal à vivre dans les pratiques des enseignants. En rajoute que, la volonté de programme de développer la notion de la pensée scientifique en électricité en lien avec l’expérimentation et la modélisation n’ait été que peu prise en compte dans les manuels, et soit difficilement stable dans les pratique des enseignants. Le manque des outils de laboratoire et les classes surchargées pourraient être un argument pour supprimer les activités expérimentales dans la majorité des cours en électricité
The current studies are interested in different physics concepts which are related to the electricity and teaching these concepts at schools in Syria. Sometimes, these concepts are difficult to understand by the students, moreover, to the teachers to teach. These concepts are formally being taught to fifth class at Syrian schools. In the beginning, the goal of this research was to study the different ways to present the notions of electricity in the knowledge of reference. Therefore, we have chosen three university works of the electricity for this research. Then we have examined the choice which was taken by the institution to teach this notion. We specify that we are interested in the content of choices and also in the methods of their teaching suggested in the program of pre-university education in Syria. Afterwards, we also have viewed the choices which are existed in textbooks of the 5th,6th, 7th, 8th,and 9th class in Syria which are equivalent to the 6th , 4th, 3th, and CM2 class in France. Moreover, the aim of this research is to figure out an idea about the opinions of teachers who are considered the key players in this renovation. For this, a sample of 30 physics teachers at schools in Syria have answered a written questionnaire about the teaching of different concepts of the electricity. The goal is to study the conceptions and the representations on the electricity for their students. Besides, the difficulties encountered such concept especially with regard to various didactic notions recommended to teach these concepts at schools. Finally, our study shows that despite the big support in the programs and the textbooks on the importance of addressing the concepts of electricity with an experimental method, the use of experimental and analogue in the teaching at schools remain minus in Syria. Thus, in order to know pedagogical and epistemological concepts of teachers in their approaches while teaching electricity, we have constructed the data by a questionnaire of 30 teachers. The answers to this questionnaire were analyzed by two perspectives, the pedagogic and didactics perspectives. As for the pedagogical feature analysis, a grid was built around privileged methods of representation by the masters and around the roles reserved for the teachers and the students. In parallel, we have checked their mastering level of the concepts in science education. So the teachers have said that to introduce the concepts of electricity they had specialized ample room for experimental activities when the circumstances are appropriate. The analysis carried on the textbooks was made by using analytical framework, the results of analysis of these manuals show that the implementation of proposals for an experimental approach with a modeled recourse remained under valuable in the latter. Moreover, the study of this questionnaire tells us that for teachers this experimental process in connection with an electricity investigative approach is hard to be applied in teacher practice. The program will develop the concept of scientific thought in electrical connection with experimentation and modeling have been a little consideration in textbooks and are hardly stable in teachers 'practice. There is no room for discussion that the lack of laboratory tools and the overcrowded classrooms could be an argument to weaken experimental activities in the majority of current electricity

Abstract:
O presente trabalho teve como escopo analisar os aspectos que evidenciem os processos de elaboração conceitual de Licenciandos em Química de uma Universidade do Estado de São Paulo, com foco especificamente nos conteúdos de química que são base para compreender fenômenos do contexto cotidiano. Buscou-se compreender, junto a Licenciandos em Química, como eles entendem e/ou utilizam os conhecimentos aprendidos na Universidade para explicar fenômenos cotidianos, já que é uma das demandas, segundo Documentos Oficiais de Educação do Estado de São Paulo. Primeiramente, foi analisada a Proposta Curricular do Estado de São Paulo e o Caderno do Aluno (química) e, em um segundo momento, o Projeto Pedagógico do Curso de Licenciatura em Química da FFCLRP e as ementas das disciplinas deste curso. Foram realizados encontros com duplas e trios de licenciandos em química, totalizando 15 alunos. Os encontros aconteceram em forma de discussão orientados por um questionário-base com questões do Caderno do Aluno que apresentam a contextos do cotidiano. Os diálogos foram transcritos, organizados em episódios e analisados com base nos referenciais teóricos da Abordagem Histórico-Cultural. Os resultados obtidos das análises do Caderno do Aluno mostraram que a intenção de contextualizar no cotidiano ocorre por meio de exemplificações e exploração das concepções prévias dos alunos. Nos cadernos foram analisadas as Situações de Aprendizagem que partem de um fenômeno cotidiano para, então, inserir os conceitos científicos pertinentes ao tema. Nestes casos, as discussões se dão através de interpretações de textos e produções de dissertações, ou orientações para visitas técnicas à estações de tratamento de água/esgoto; usinas de reciclagem; etc. As produções coletivas dos Licenciandos sobre os conhecimentos científicos, nos mostraram que a construção deste conhecimento passa por complexos processos de desconstrução e reelaboração; evoluções e involuções, portanto, não ocorre de forma linear e; mesmo no último ano do curso, a explicitação dos fenômenos cotidianos não ocorre de forma clara e cientificamente adequada, apresentando grande esforço destes alunos para explicarem à nível microscópico e simbólico fenômenos que ocorrem a nível macroscópico.
This study has analyzed the concept`s evolution and elaboration process of Teaching in Chemistry degree students from a University in Sao Paulo state, being the main focus the chemical knowledge that is extremely important to comprehend daily phenomena of everyday life. It has been discussed how the Teaching in Chemistry process contributes to the future teachers` formation since it is important that these professionals possess chemical knowledge in a daily context as it is required by Primary Education institutions. Firstly, was analyzed the Curriculum Proposal for Sao Paulo state along with the Student Handout (Chemistry) were analyzed, and sequentially, the Teaching in Chemistry degree Pedagogical Program and the course syllabus were also discussed. A survey with questions presenting topics on every day phenomena extracted from the Chemistry Handout was applied to the Teaching in Chemistry students (15 students in total). The results observed have shown that the contextualization in an everyday basis is given through examples and exploitations of previous concepts these students might have. In the notebooks we analyzed the Learning Situations, such as the ones that explore the daily phenomena previously and, the pertinent scientific concepts are introduced later are in most cases, discussed among the students using text reading or interpretation, essay writing and/or guided technical visits to water/waste treatment stations, recycling plants, etc. The students scientific knowledges have presented that the construction of this kind of knowledge undergoes complex processes of its destruction and elaboration, evolutions and involutions. Therefore, it does not occur linearly and, even senior students cannot provide clear and scientifically adequate answers to all the questions, which presents a great challenge to these students when it is necessary to explain a phenomenon under a symbolic and microscopic levels what happens in the macroscopic level.

This research has the purpose of analysying the influence of the Psychoanalysis through thesis and essays on the education field. Having as a goal the analysys of the theoretical trends on studies about Psychoanalysis found in thesis and essays of the College of Education s digital library , this research tried to characterize these papers and verify their theoretical trends and, as a result verify, as well, the psychoanalytic concepts found in those papers. Through the reading of the summaries of all the available on line thesis and essays, these papers had been grouped in themes. The interpersonal relations theme was the focus of this research, due to the fact that the influence of the Psychoanalysis in this theme was considered greater. The papers of this group had been read in the whole and analyzed in two aspects. First they had been evaluated according to the quality of the production based on the ARR scale. After that the psychoanalytic concepts in every work were analyzed based on one of the Psychoanalysis introductory texts. The results were that the papers have many deficiencies in the qualitative aspect of the scientific productions. And the concepts are not only diluted in the works of the education field, but also presented in a superficial way and without the complexity and deepening of each one. These results showed the subtle influence that these papers of the education field suffer from the Psychoanalysis and that terms of this theory are used in a superficial way and little deepened, disclosing the idea of the common sense regarding the Psychoanalysis that also is present in these papers.
Esta pesquisa se prop?e a analisar a influ?ncia da Psican?lise na Educa??o atrav?s de teses e disserta??es da ?rea escolar. Com o objetivo de analisar as tend?ncias te?ricas dos estudos sobre Psican?lise nas teses e disserta??es na biblioteca digital de uma faculdade de Educa??o, este trabalho procurou caracterizar essas produ??es e verificar suas tend?ncias te?ricas, verificando assim os conceitos psicanal?ticos presentes nestas pesquisas. Atrav?s da leitura dos resumos de todas as teses e disserta??es dispon?veis online , os trabalhos foram agrupados em tem?ticas. A tem?tica rela??es interpessoais foi o foco desta pesquisa, pois considera-se que a influ?ncia da Psican?lise nessa tem?tica seria maior. Os trabalhos desse grupo foram lidos na ?ntegra e analisados em dois aspectos. Primeiramente foram avaliadas quanto a qualidade da produ??o atrav?s da escala ARR. Depois foram analisados os conceitos psicanal?ticos presentes em cada trabalho com base em um dos textos iniciais da Psican?lise. Os resultados demonstraram que os trabalhos se apresentam com muitas defici?ncias no aspecto qualitativo das produ??es cient?ficas. E os conceitos psicanal?ticos, al?m de bastante dilu?dos nos trabalhos da ?rea escolar, apresentam-se de forma superficial e sem a complexidade e aprofundamento de cada conceito. Esses resultados apontam que esses trabalhos da ?rea escolar sofrem uma influ?ncia sutil da Psican?lise e que se utilizam de termos dessa teoria de forma superficial e pouco aprofundada, revelando a id?ia do senso comum a respeito da Psican?lise que tamb?m est? presente nesses trabalhos.

Abstract:
A síntese, que segue, visa examinar de que modo acontece o processo de formação de conceitos científicos em crianças com necessidades educacionais especiais na 1ª série do ensino fundamental. Para tanto, tomou-se como suporte conceitual os postulados da psicologia sócio-histórica de Vygotsky e seus contemporâneos Luria e Leontiev. Esses autores encerram um alinhamento teórico em relação ao desenvolvimento das funções psicológicas superiores "avançadas" - com relevo especial no que se refere aos conceitos científicos - como um processo que pressupõe constantes interações com signos e ferramentas culturais em situações específicas, como, por exemplo, o espaço escolar. Salienta-se que Vygotsky (1928) considerava os processos de escolarização, mais precisamente a inserção de crianças com necessidades especiais na escola regular, como imprescindíveis para que houvesse a apropriação instrumental que proporcionasse não apenas o manejo sociocultural, mas o constituir-se como um ser humanizado, pertencente ao gênero humano. Partindo desse ideário, precursor nos processos de integração/inclusão, a implementação da pesquisa aconteceu em uma escola de educação básica da cidade de Santa Maria/RS, mais precisamente em duas primeiras séries do ensino fundamental, junto a três crianças consideradas com necessidades educacionais especiais, com idades variando entre oito e onze anos. Os aspectos operacionais da investigação se desenrolaram através da análise qualitativa de caráter etnográfico, especificamente por de três estudos de caso, utilizando-se como instrumentos para a coleta de dados: anotações de campo, entrevistas planejadas e estruturadas, análise de documentos, que possibilitaram a elaboração de uma matriz conceitual. Os resultados obtidos estabeleceram diversos momentos desse processo formativo, os quais incorporaram características de transitividade, relatividade, apropriação dinâmica e conscientização em termos de generalização conceitual, pois estiveram imersos em um processo de formação que não tem um fim em si mesmo, mas que se encontra intimamente vinculado ao entorno sociocultural presente no universo escolar. As conclusões confirmam o caráter indispensável da escolarização como um grande propulsor na formação das funções psicológicas superiores, particularmente no que se refere aos conceitos científicos. E, ainda, ratificam a hipótese da escola regular como locus relevante, onde se evidenciam muitos dos constructos intelectuais necessários à interação cultural por parte de crianças consideradas com necessidades educacionais especiais.
The following synthesis aims for examining in which way the formation process of scientific concepts happens in children with special educational needs in the first grade of fundamental school. Postulate of socio-historical psychology of Vygostsky and his contemporaries Luria and Leontiev were used as conceptual supporting. These authors close a theoretical alignment in relation to the development of "advanced" superior psychological functions - with special attention to scientific concepts - as a process which presupposes constant interactions with cultural signs and tools in specific situations, for example, the school space. It points out that Vigotsky (1928) considered the school processes, more precisely the insertion of children with special needs in regular school, as essential so that instrumental appropriation occurred and offered not only the sociocultural handling but also the 'constitute oneself' as a humanized being, pertaining to human gender. From this idea, precursor in the integration/inclusion processes, the research implementation took place in a basic educational school in the city of Santa Maria/RS, more precisely in the two first grades of fundamental education, along with the three children considered with special educational needs, between eight and eleven years old. The operational aspects of investigation unfolded through qualitative analysis of ethnographic character, specifically through three case studies, using as instruments to data collection: notes, planned and structured interviews, analysis of documents, which permitted the elaboration of a conceptual matrix. The obtained results established several moments of this formative process, in which incorporated characteristics of transitivity, relativity, dynamic appropriation and awareness in terms of conceptual generalization since they were immersed in a formation process that do not have an end in itself, but it is intimately linked to the sociocultural spread presented in the school universe. The conclusions confirm the indispensable character of 'schooling' as a big propeller in the formation of superior functions, particularly in relation to scientific concepts. And they still ratify the hypothesis of the regular school as relevant locus where several intellectual constructions needed to cultural interaction by children considered with special educational needs were evident.

Abstract:
Recent anti-evolution legislation, in the form of Academic Freedom bills, has been introduced in many state legislatures over the last three years. The language in the proposed Academic Freedom bills may allow different interpretations of what can be taught in the science classrooms, and possibly spur parents to take advantage of their perceived parental rights to request their child be opted-out of class when the scientific theory of evolution is taught. Five research questions guided the analysis of participant responses to questions and perception statements focusing on secondary school administrators' actions, perceptions, and awareness as they relate to their decision to allow or not allow a student to opt out of academics, specifically evolution, through the collection of data using a web-based survey. Opt out policies are typically invoked to excuse students from activities to which they or their parents may have religious objections (Scott & Branch, 2008). Florida statutes allow parents to opt out their child from human sexuality and animal dissection. The population consisted of 281 Florida public secondary school administrators, who were divided into two subgroups based on whether they have allowed or would allow a student to opt out of evolution, or have not allowed or would not allow a student to opt out of class when the scientific theory of evolution is taught. Results found that over 70% of the administrators who completed the survey have allowed or would allow parents to opt out their child from learning about the scientific theory of evolution. There was a significant relationship between the decision to allow opt out and the following variables: (a) Free and Reduced Lunch population, (b) grade level served, (c) support for teaching evolution and alternative theories, and (d) the perception that parent rights supersede state statute requiring students to learn evolution. In Florida, any scientific concept that is based on empirical evidence is included in the state-mandated curriculum. If administrators are influenced to believe teachers have the academic freedom to teach alternative ideas that are not scientifically valid, they may be intentionally or unintentionaly allowing subject matter relevant to a student's academic success t to be suppressed or distorted, which is also a violation of state statute. The implications from this study indicated that many participants would allow a student to opt out of class when evolution is taught, including assigning an alternative assignment. Since the scientific theory of evolution is infused into the biological sciences, and therefore, the Florida State Standards for science, evolution concepts are assessed on the Florida Comprehensive Assessment Test (FCAT) and the Biology End-of-Course exam. Allowing students to opt out of class when evolution is taught may have a negative impact on student success on state mandated assessments, which can directly impact school grades and state and federal funding that is tied to Adequate Yearly Progress.

Abstract:
A presente Tese de doutorado aborda a audiodescrição na mediação do processo de ensino e aprendizagem de alunos com deficiência visual na disciplina de Geografia, no Ensino Médio do Colégio de Aplicação da Universidade Federal do Maranhão (COLUN/UFMA). A audiodescrição é definida como um modo de tradução audiovisual intersemiótico, em que o signo visual é transposto para o signo verbal. O problema de pesquisa buscou compreender de que forma a audiodescrição, media a apropriação de conceitos científicos de Geografia por alunos com deficiência visual no Ensino Médio. Uma vez que tem aumentado o número de matrículas de alunos com deficiência visual na educação básica, há a necessidade de se criar alternativas e estratégias pedagógicas diferenciadas, principalmente para os componentes curriculares que se utilizam predominantemente de recursos visuais, como é o caso da Geografia. A pesquisa foi de cunho qualitativo, do tipo pesquisa-ação, na qual participaram dois alunos com deficiência visual, cinco alunos sem deficiência visual e um professor de Geografia, os quais passaram por um processo de estudos e construção coletiva dos conteúdos de Geografia com audiodescrição. Fundamentou-se na teoria sócio-histórica, por entender que as relações entre os seres humanos não acontece individualmente, mas por meio da interação social. As principais etapas foram: a) realização de estudos dirigidos, em que visou-se compreender o potencial e as limitações da audiodescrição nos conteúdos curriculares de Geografia; b) Planejamento colaborativo do professor, junto aos alunos para atender as necessidade de formação docente, bem como compreender as necessidades dos alunos com deficiência visual; c) O uso e a aplicação da audiodescrição nas aulas e por fim, a análise e discussão dos dados coletados. Os resultados apontaram que a inserção da audiodescrição nos conteúdos de Geografia, proporcionou uma apropriação mais qualificada dos conceitos científicos pelos alunos com deficiência visual, permitindo entre outras questões a equiparação de oportunidades educacionais, o acesso ao mundo dos conteúdos imagéticos e a eliminação de barreiras comunicacionais entre os participantes.
This doctoral dissertation addresses audio description in mediating the teaching and learning process of visually impaired Geography students at the Colégio de Aplicação High School of the Federal University of Maranhão (COLUN/UFMA). Audio description is defined as an intersemiotic audiovisual translation in which the visual signal is exchanged for a verbal one. The research problem sought to understand how audio description mediates the appropriation of the scientific concepts of Geography by visually impaired high school students. Given the increase in the number of visually impaired students enrolled in basic education, there is a need to create unique pedagogical alternatives and strategies, particularly for subjects that use predominantly visual aids, such as Geography. Participants in this qualitative action research were two visually impaired and five unimpaired students, as well as a geography teacher, who underwent a series of studies and collective construction of Geography content with audio description. The study was based on sociohistorical theory, since relationships between human beings do not occur on an individual level, but through social interaction. The main stages were: a) targeted studies aimed at understanding the potential and limitations of audio description in Geography content; b) collaborative planning between the teacher and students to cater to teacher training requirements and understand the needs of visually impaired students; c) the use and application of audio description in classes and, finally, analysis and discussion of the data collected. The results showed that the use of audio description in Geography content enabled more skilled appropriation of the scientific concepts by the visually impaired students ensuring, among other issues, equal educational opportunities, access to the world of image content, and the eradication of communication barriers among the participants.

The aiming of this work is linked to chemical education, focusing organic chemistry classes of Chemical Engineering, Pharmacy and Zootechny graduate courses of the Federal University of Rio Grande do Norte. For that, teaching-learning process related to basic chemical subjects which support the understanding of organic chemistry concepts was evaluated in a research period of two years. The education proposal linked to the theoretical content of the cited classes, pointed out the process of knowledge construction, in which educational commitment as well as dedication in the teaching-learning process was also valued. In that approach several didactic tools were applied, among them scientific articles were used as supplementary studies of the basic organic chemistry concepts and related. The acceptability of students, as well as their motivation, performance and learning process was justified by the data collection of the applied teaching methodology. The acceptability and commitment of the students facing this teaching interactive approach, which transversely contributed to the intellectual maturity growth of the students, as well their professional development, were evidenced by satisfactory obtained results that will be herein discussed

Abstract:
Notre travail de recherche vise deux objectifs étroitement liés. Le premier consiste à proposer une aide à l’évaluation des écrits scientifique et pour cause : le nombre de publication augmente, les limites entre les domaines deviennent floues, et il devient difficile de trouver des publications pertinentes si bien qu’un besoin pratique d’évaluation surgit. Il s’agit aussi de trouver les moyens d’une aide à l’expertise, appuyée sur des indices discursifs permettant d’aider le lecteur à repérer les points clés d’une publication (phase préalable à une évaluation) notamment à travers l’identification du problème de recherche. Ces indices qui annoncent la formulation du problème de recherche dans les articles scientifiques sont repérables sous forme de « formules de discours ». Notre recherche ne s’étend pas sur la formulation de la problématique scientifique au vu de la complexité de cette notion et de la difficulté de la définir d’un point de vue de l’extraction d’information. Nous proposons une modélisation de ces formules de discours que nous avons intégrée dans l’analyseur syntaxique Xerox Incremental Parser (XIP) sous forme de règles de reconnaissance. Nous avons utilisé un corpus d’articles de recherche en sciences de l’éducation extraits du corpus Scientext pour y détecter ces formules de discours. Le choix du domaine est motivé par ma participation au projet européen EERQI dont le but est de renforcer et d’améliorer la visibilité mondiale et la compétitivité de la recherche européenne en éducation. Différentes approches méthodologiques ont été adoptées afin de procéder à une étude linguistique fine de ces formules dîtes de discours entre autres : l’analyse de discours (M. Pecman, 2004, K. Hyland, 2005, Á. Sándor, A. Kaplan, G. Randeau, 2006, D. Siepman, 2007, A. Tutin, 2007-2010), robust parsing (S. Aït-Mokhtar, J. Chanod, R. Roux, 2002). Il s’agit donc de mettre en œuvre une approche applicative en vue de l’aide à la lecture experte à travers l’identification, la typologie et le fonctionnement des associations lexicales véhiculant le problème de recherche
Our research focuses on two interrelated objectives. The first one aims at providing assistance to the evaluation of scientific writings because of; the numbers of publication, which keep on rising, the boundaries between the areas become and it's becoming more and more difficult to find relevant publications so as the practical need for assessments is appearing as unavoidable. We also have to find new ways to help the evaluation of the research work, through a wide range of indications different from those usually used for research assessment, notably, through the identification of the research problem. These indications that announce the formulation of the research problem in scientific articles can be identified as "speech formulas." Our research does not extend to the formulation of the scientific problem because of the complexity of this concept and the difficulty of defining it from the point of view of information extraction. We propose a model of the speech forms that we have integrated into the parser Xerox Incremental Parser (XIP) in pattern recognition rules. We used a corpus of Educational Sciences Research articles from the Scientext corpus to detect these speeches formulas. The choice of field is motivated by my participation in the European project EERQI which aims to strengthen and enhance the worldwide visibility and competitiveness of European research in education. Different methodological approaches were adopted to perform a fine linguistic study of these formulas as: discourse analysis (Mr. Pecman, 2004, K. Hyland, 2005, Á, Sándor A. Kaplan, G. Randeau, 2006, D. Siepman, 2007, A. Tutin, 2007-2010), robust parsing (S. Aït-Mokhtar, J. Chanod, R. Roux, 2002). Thus, the goal is to implement an applicative approach aiming at helping expert reading through the identification, typology and functioning of lexical associations which convey the research problem

COORDENAÇÃO DE APERFEIÇOAMENTO DO PESSOAL DE ENSINO SUPERIOR
O estudo focaliza a noção de alfabetismo científico, a partir de uma abordagem multifocal, que procurou englobar aspectos culturais, políticos e sócio-lingüísticos. Buscou- se dimensionar em que medida o ensino de Biologia tem contribuído para o desenvolvimento dos níveis de alfabetismo científico e, consequentemente, para a consolidação de uma percepção mais ampla, entre estudantes de nível médio, provenientes das camadas populares, de questões de grande relevância social, como é o caso da temática ambiental. Para a verificação dos níveis de alfabetismo científico, tomou-se como referência a análise da Matriz de Competências do ENEM e da proficiência em Ciências dos estudantes, a partir dos resultados de provas simuladas do ENEM, aplicadas aos 2783 alunos dos 97 Cursos Pré- Vestibulares Comunitários (CPVC) parceiros da PUC-Rio. Foram também realizadas entrevistas com professores de Biologia desses cursos. Os resultados apontam para a necessidade de uma revisão crítica do ensino de Biologia nos CPVC, ainda pautado numa visão propedêutica de difícil desconstrução. Propõe-se a busca de procedimentos técnico-pedagógicos que estimulem a criticidade e a participação político-social, visando à superação de práticas sociais excludentes, contra as quais se mobilizam expressivas alternativas de ação afirmativa e de inclusão, tais como o movimento social dos CPVCs.
The thesis studies the meaning of Scientific Literacy, at the threefold level of its cultural, political and sociolingustic dimensions. It focuses on what extension the Biology teaching in high schools enhances the development of Scientific Literacy, in relation to relevant social issues, such as the environment. The research is carried among low income high school graduates nowadays enrolled in CPVCs (community classes in poor neighborhoods preparing high schools graduates to overcome the selective process of university entrance examinations). The study of the Scientific Literacy levels is referred to the competencies matrix developed by ENEM (the National Examination on Senior High Schools), insofar as the proficiency levels demonstred by 2783 high schools graduates enrolled in 97 CPVCs. The research was complemented through semi-structured interviews with teachers of those CPVCs. The thesis conclusions stress on the need of carrying a critical revision of the Biology teaching among CPVCs, since their pedagogical project is mostly targeted at the propedeutic aim of succeeding in the university entrance examinations. The thesis proposes then the development of teaching procedures that stress criticism and social- political participation, in order to overcome exclusion practices in schooling, such as those carried out by social movements.

The Theory of Evolution is considered by scientists and studies of teaching biology as a unifying content of all other content Biology. Theodosius Dobzhansky expressed this importance of the theory of evolution to biology in his famous phrase, "Nothing in Biology makes sense except in light of evolution." The National Curriculum Guidelines also indicate that the Theory of Evolution of content should be worked throughout basic training, constantly permeating the rest of biology content. But not always this work of evolutionary theory unifying mode occurs between the difficulties that this goal is achieved are: the traditional approach of content in most schools; the simplification of scientific concepts of the theory, thus distorting such concepts; the interference of religious beliefs of teachers and students in working with this theme; among others. increased attention to initial and continuing training of teachers in relation to this content, thereby contributing to that are prepared to deal with such difficulties do is important. This research aimed to analyze the process of construction of scientific concepts of the theory of evolution, according to the Vigotski`s theory, for the work of such content through a variety of teaching methods, including: reflective readings paradidactic texts; dialogued classes; documentary presentation; debate and discussion; and construction and presentation of theatrical skits. All the process was recorded on video and audio, and then used for the analysis of the speeches and participation of students. As a result of analysis of these records was possible to realize the criticality and interest that students have shown in their questions, thoughts, observations and placements. It was also possible indentify the enlargement of scientific concepts of evolutionary theory, as they were able to make relationships between concepts that were presented . And we can also point out that the study of the Theory of Evolution contributes significantly to working with students in relation to science and construction processes of scientific knowledge.
A Teoria da Evolução é considerada por cientistas e estudos do ensino de Biologia como sendo um conteúdo unificador de todos os outros conteúdos da Biologia. Theodosius Dobzhansky expressa essa importância da Teoria da Evolução para a Biologia em sua conhecida frase: “Nada em Biologia faz sentido, exceto à luz da Evolução”. As Orientações Curriculares Nacionais também indicam que o conteúdo da Teoria da Evolução deve ser trabalhado ao longo de toda a formação básica, permeando constantemente os demais conteúdos da Biologia. Porém, nem sempre este trabalho da teoria evolutiva de modo unificador ocorre, entre as dificuldades para que tal objetivo seja alcançado estão: a abordagem tradicional de conteúdos na maioria das escolas; a simplificação dos conceitos científicos da teoria, distorcendo assim tais conceitos; a interferência das crenças religiosas de professores e alunos no trabalho com essa temática; entre outras. Faz-se importante uma atenção maior à formação inicial e continuada dos professores em relação a este conteúdo, contribuindo assim para que estejam preparados para lidar com tais dificuldades. Esta pesquisa buscou analisar o processo de construção de conceitos científicos da Teoria da Evolução, segundo a teoria de Vigotski, durante o trabalho de tal conteúdo por meio de diversas metodologias pedagógicas, incluindo: leituras reflexivas de textos paradidáticos; aulas dialogadas; apresentação de documentário; debate e discussões; e construção e apresentação de esquetes teatrais. Todo o processo foi registrado em áudio e vídeo, sendo em seguida utilizados para a análise das falas e participações dos alunos. Em decorrência da análise desses registros foi possível perceber a criticidade e interesse que os alunos demonstraram em seus questionamentos, reflexões, observações e posicionamentos. Foi possível identificar também a ampliação de conceitos científicos da teoria evolutiva, visto que conseguiram realizar relações entre os conceitos que lhes foram apresentados. Sendo possível ressaltar também que o estudo da Teoria da Evolução contribui bastante com o trabalho com alunos em relação à Ciência e os processos de construção de conhecimentos científicos.

Of necessity LOSC Articles are brief and in some instances vague and requiring interpretation. There is general consensus that LOSC is successful and that its vagueness in certain areas is an asset allowing a variety of otherwise contrary attitudes to be accommodated. 1 It is necessary to analyse the Articles with a view to a better understanding of them and to possibly prepare for some future conference or convention that will more than likely be necessary to resolve some of the remaining problems. To illustrate the need for greater understanding of some of the Articles of LOSC the United Nations Office for Ocean Affairs and Law of the Sea found it necessary to convene a conference of 'experts' during 1993 and 1995 to consider the implications of the complex Articles of LOSC which deal with claims to the continental shelf. Criteria contained in Article 76 allowing for maximum outer limits of the continental shelf and other criteria to justify a claim are complicated and require experience in many fields including marine geology, geography, surveying, and geodesy.2 The intention is therefore to analyse the possible interpretation, application and consequences of the implementation of Articles in LOSC, and more particularly in a Southern African context. Provisions of LOSC, where technical and scientific considerations are crucial, will be selected for consideration. These include those involving geodetic, geographical, geological, survey, navigational, organisational, and social and resource factors.

Abstract:
Este trabalho trata da mediação simbólica empreendida por professoras, com crianças do segundo ano1 e da quarta série2 de uma escola do Ensino Fundamental. A reflexão dessas práticas é feita à luz de pressupostos teóricos interacionistas. Foram investigadas, nas duas turmas, as formas de apresentação dos conteúdos, as tarefas cooperativas, as representações do objeto de estudo, os conhecimentos trazidos pelos alunos e a socialização do conhecimento. A pesquisa exploratória foi do tipo etnográfico com observação, entrevistas, diário de campo e o registro, num quadro de referências, de indicadores de formação de conceitos científicos, elaborados a partir dos referenciais teóricos de Vygotsky. Dos resultados obtidos, em muitas situações, as aulas observadas obedeceram a uma dinâmica de exposição oral e os conteúdos surgiram de seleção feita pelas professoras a partir de listagem combinada por classes paralelas e livros didáticos. Em outros momentos, foram desenvolvidos projetos que surgiram dos interesses demonstrados pelos alunos e trabalhados em moldes cooperativos, nos quais fizeram explorações concretas dos temas de estudo. Os resultados indicam que quando o grupo trabalhou com os projetos, os resultados foram melhor formalizados em função do tipo de envolvimento dos alunos com o objeto do conhecimento na possibilidade de relações e associações cooperativas. Quando as crianças trabalharam com princípios teóricos formais propostos pelas professoras o caminho para a formação de conceitos e generalizações se expressaram de modo mais restrito. As atividades do grupo que eram originadas em projetos da escola, com temas do cotidiano, e propostas a partir das necessidades e interesses dos alunos, revelaram maior interação e apropriação do conhecimento por parte deles. Os resultados das observações e entrevistas estão analisados principalmente a partir da mediação simbólica de Vygotsky, na qual a linguagem, os signos e símbolos verbais e não verbais compartilhados nas relações sociais medeiam o processo de aquisição de conhecimento. Em Piaget, o enfoque da epistemologia genética, enquanto operacionalidade construtivista, possibilitou a reflexão sobre a interação do sujeito com o grupo e também com o objeto do conhecimento. A presença de Bakhtin, neste trabalho, mostrou uma visão da linguagem, que ultrapassa os códigos linguísticos, pela ideologia presente nos enunciados. Esses autores e suas ideias sobre o aprendizado e o desenvolvimento complementam esse momento de pensar o fazer pedagógico no cotidiano da sala de aula.
This study is focused on the symbolic mediation undertaken by teachers in an Elementary School with children aged 7 to 8 and 10 to 16. The reflection of such practices was made in the light of interactionist theoretical assumptions. The content presentation, the cooperative tasks, the representations of the object of study, the knowledge brought by the students and the socialization of knowledge were analyzed in the two classroom groups. It was an ethnographic exploratory research with observations, interviews, field journal, and reports, within a framework of references, on indicators of scientific concept formation based on Vygotsky´s theoretical referential. From the results obtained, in many situations, the lessons observed had an oral presentation dynamics and the teacher’s content selection derived from a list that comprised parallel classes and textbooks. In other occasions, some projects were developed due to the interest demonstrated by the students and worked collectively, with a concrete exploration of the study themes. The results showed that when the group worked with projects, the results were better formalized according to the way the students were involved with the object of knowledge as to the possibility of cooperative associations and relationships. When the children worked with formal theoretical principles proposed by teachers, the way for the formation of concepts and generalizations, they were more intimidated. The group activities developed in school projects, with daily life issues, and proposals from the needs and interests of students, showed that the students had greater interaction and knowledge construction. The results of the observations and interviews were analyzed by considering Vygotsky's symbolic mediation, in which language, verbal and nonverbal signs and symbols shared in social relationships mediate the knowledge construction process. In Piaget, the focus of the genetic epistemology, as a constructivist operation, enabled the reflection on the subject's interaction with the group and also with the object of knowledge. In this study, Bakhtin´s presence provided a vision of language that goes beyond the linguistic codes due to the ideology present in statements. These authors and their ideas on learning and development complement this time of reflecting upon the teaching practice in the everyday classroom.

A pesquisa teve como objetivo planejar, implementar e avaliar uma intervenção pedagógica, à luz da Teoria Histórico-cultural da Atividade e do construto da Autorregulação da Aprendizagem, visando o desenvolvimento dos conceitos científicos de Mecânica em alunos do curso de Licenciatura em Física da Universidade Federal de Pelotas. Esse curso vem enfrentando altos índices de reprovação e evasão, principalmente nos semestres iniciais e, um dos fatores que podem estar associados a esses índices é a dificuldade de aprendizagem dos conceitos de Mecânica, que são apresentados nas disciplinas introdutórias do curso (BILHALBA; AYALA FILHO, 2012). Com o intuito de dirimir esse problema o curso de Licenciatura em Física implementou uma nova disciplina no primeiro semestre intitulada de Introdução ao Pensamento Físico, a qual intenciona desenvolver os conceitos científicos de Mecânica. No contexto dessa disciplina, foi realizada a intervenção pedagógica, que buscou promover o desenvolvimento desses conceitos, e levar os alunos a utilizarem estratégias autorregulatórias que promovessem a tomada de consciência sobre as características de seus próprios processos de aprendizagem. Essa intervenção, foi realizada no primeiro semestre, totalizando 14 aulas e com 20 alunos participantes. A pesquisa propriamente dita, de caráter qualitativo, teve como foco analisar os efeitos da intervenção, verificando se os alunos conseguiram autorregular sua aprendizagem e se avançaram no desenvolvimento dos conceitos científicos trabalhados. Os resultados mostraram que a metodologia da intervenção pedagógica, baseada no construto da autorregulação da aprendizagem e da teoria histórico-cultural da atividade, realizada na disciplina de Introdução ao Pensamento Físico, parece poder desenvolver avanços na aprendizagem dos alunos podendo inclusive ser um instrumento importante para a reformulação das disciplinas iniciais dos cursos de Física.
The research aimed to plan, implement and evaluate a pedagogical intervention in the light of historical-cultural Theory of Activity and construct of Self-Regulation of Learning, for the development of scientific concepts in mechanics students of Degree in Physics from the Federal University Pelotas. This course has been facing high rates of failure and dropout, particularly in the early semesters and one of the factors that may be associated with these indexes is the difficulty of learning the mechanics concepts that are presented in the introductory course subjects (BILHALBA; AYALA FILHO, 2012). In order to resolve this problem the Degree in Physics implemented a new discipline in the first half titled Introduction to Physical Thought, which intends to develop scientific concepts of mechanics. In the context of this discipline, the educational intervention was carried out, which sought to promote the development of these concepts; and lead the students to use self-regulatory strategies that promote the awareness of the characteristics of their own learning processes. This intervention was carried out in the first half, totaling 14 classes and 20 students participating. The research itself, qualitative, focused on analyzing the effects of intervention, making sure that the students could self-regulate their learning and advanced the development of scientific concepts worked. The results showed that the methodology of pedagogical intervention, based on the self-regulation of learning and construct cultural-historical activity theory, held in an Introduction to Physical Thought, seems able to develop advances in student learning and may also be an important tool for the reformulation of the initial disciplines of physics courses.

Esta pesquisa, de natureza qualitativa e base etnográfica, objetiva investigar a (co) construção de conhecimentos teórico-práticos na formação inicial de professores de língua inglesa no norte do Brasil a partir de uma perspectiva sociocultural, conforme proposta por, principalmente, Johnson (2009), Vieira-Abrahão (2012), Johnson e Golombek (2011, 2016) e Lantolf e Poehner (2014), respondendo à grande pergunta de pesquisa: Como se dá a (co) construção de conhecimentos teórico-práticos na formação inicial de professores de inglês em uma universidade pública no norte do Brasil?. Outras três questões orientaram o desenvolvimento desta investigação: (1) Quais conceitos cotidianos e científicos de língua, ensino e aprendizagem são apresentados pelos alunos-professores antes de cursarem a disciplina de Metodologia I?; (2) Quais conceitos científicos de língua, ensino e aprendizagem são introduzidos e de que modo são trabalhados nas disciplinas de Metodologia I e II e Estágio I e II?; (3) Quais conceitos cotidianos e científicos de língua, ensino e aprendizagem podem ser inferidos das práticas e dos discursos dos alunos-professores por ocasião dos estágios supervisionados e como esses conceitos se relacionam aos conceitos científicos introduzidos nas disciplinas de Metodologia I e II e Estágio I e II? . Os instrumentos de coleta e geração de dados utilizados foram gravações de aulas em áudio, diários da pesquisadora, questionários, sessões de feedback, entrevistas e relatórios de estágio. Os resultados mostraram que a maioria dos conceitos de língua, ensino e aprendizagem apresentados pelos futuros professores refere-se a concepções tradicionais. Os conceitos científicos de língua, ensino e aprendizagem introduzidos no curso de formação são oriundos dos paradigmas estrutural e comunicativo de ensino de línguas estrangeiras e foram diretamente transmitidos aos alunos-professores. No estágio supervisionado, os conceitos que sobressaíram possivelmente dizem respeito aos adquiridos por meio da aprendizagem de observação, com pouca influência dos conceitos introduzidos no curso de formação.
This ethnographic and qualitative research study aims at investigating the (co) construction of teacher knowledge in initial teacher education in the north of Brazil from a sociocultural perspective as proposed mainly by Johnson (2009),Vieira-Abrahão (2012), Johnson and Golombek (2011, 2016) and Lantolf and Poehner (2014), answering the major research question: How does the (co) construction of teacher knowledge occur in initial teacher education in the north of Brazil?. Three other questions oriented the development of this investigation: (1) What language, teaching and learning everyday and scientific concepts are held by teacher-learners before taking Metodologia I? (2) What language, teaching and learning scientific concepts are introduced and how are they worked in Metodologia I and II and Estágio I and II?; (3) What language, teaching and learning everyday and scientific concepts can be inferred from the teacher-learners’ practices and discourses at internship and how are these concepts related to the scientific ones introduced in Metodologia I and II and Estágio I and II? The instruments used to collect data were audio class recordings, researcher’s diaries, questionnaires, feedback sessions, interviews and internship reports. The results showed that most language, teaching and learning concepts held by the future English teachers refer to traditional conceptions. The language, teaching and learning scientific concepts introduced in the teacher education program came from structural and communicative paradigms in the second language teaching framework and were directly transmitted to teacher-learners. At internship the inferred concepts are likely to refer to the ones acquired through apprenticeship of observation, with little influence from the ones introduced in the teacher education program.

Abstract:
The dissertation is a biography of the industrialist and statesman Christian Lundeberg, a leading and stongly pronounced conservative actor in Swedish political life during the decades around1900, but nowadays almost forgotten. The purpose is to identify the main forces – convictions as well as external factors – behind his actions. He was very influential within  a range of important sectors, i.a. compulsory national service, repeated interventions to keep the iron ore of Norrland under Swedish ownership,  establishment of a regular conservative party and the decision on the vote to right (for men) in 1907. His most well-known action was as Swedish Prime Minister and head architect behind the peaceful dissolution in 1905 of the union with Norway. However for a long time biographies have not been regarded as ”real” scientific work within the concerned academic Swedish circles. For this reason the introductory chapter analyses these discussions  and  concludes that time now is ready for the genre to come in from the cold , enumerating six criteria regarded to be of paramount importance. These are being observed in the consecutive parts of the study. The following chapter studies the concept of paternalism as defined within Swedish professional circles, forming a background to the remaining parts of the dissertation. In their turn these present thorough reviews both of Lundeberg’s activities as a paternalistic foundry proprietor in the local family owned community of Forsbacka and of his contributions on the central political level. The final chapter summarizes the driving forces behind Lundeberg’s activities in stating that he was not an ultraconservative person, a priori opposing all progress.  Instead as the years passed he developed a clear readiness for compromise solutions. Three key concepts are said to be central to the understanding of his person: “Fatherland”, ”Responsibility” and “Duty”.  Throughout all his life he adhered to many of the paternalistic principles and values he learnt at an early age in Forsbacka. His present anonymity is explained  by the fact that he in a retrospective very often is considered as being defeated in a number of political convictions now regarded as important.

Abstract:
Com a adoção de diferentes estratégias de pesquisa identificadas no texto como “Números”, “Conceitos” e “Quase letras”, a tese busca compreender as relações entre as condições de atuação científica, os comportamentos informacionais dos pesquisadores, as características das publicações científicas e os condicionantes do reconhecimento científico internacional no contexto brasileiro. Em “Números”, são apresentados os resultados da pesquisa bibliométrica realizada para caracterizar a produção e o impacto de certas áreas de pesquisa no Brasil, considerando a origem (nacional ou estrangeira) dos periódicos utilizados para a publicação de resultados, assim como a colaboração internacional. A amostra foi constituída por artigos com autoria de pesquisadores brasileiros em 19 subáreas do conhecimento publicados no período de 2002 a 2011, totalizando 85.082 artigos. Para o cálculo do impacto, foi utilizado um indicador normalizado denominado Relative Subfield Citedness (Rw), adotando uma janela de 5 anos para obtenção de medidas avaliadas em 2 anos distintos: 2007 e 2012. Os dados de artigos e citações foram coletados na base de dados Web of Science. Dos resultados obtidos, destaca-se que grande parte das subáreas apresentou, de 2002/2006 para 2007/2011, uma melhoria de desempenho nos rankings mundiais de produção. Em relação à publicação em periódicos nacionais e estrangeiros, foi observada uma tendência de manutenção da distribuição da produção das subáreas de acordo com a origem do periódico. Especificamente sobre o impacto, identificou-se um padrão de Rw inferior dos artigos brasileiros publicados em periódicos nacionais em todas as subáreas, comparados com os publicados em periódicos estrangeiros; em algumas subáreas, inclusive, os publicados em periódicos estrangeiros superam a média de impacto mundial. Adotando outra estratégia de pesquisa, foi realizado um estudo qualitativo baseado em entrevistas com membros da Academia Brasileira de Ciências (ABC) sobre suas percepções a respeito das condições de atuação científica no Brasil, bem como de seus próprios comportamentos em relação à construção, comunicação e uso da informação científica. Em “Conceitos” é relatada a busca por uma estrutura de análise para os dados desta pesquisa qualitativa, que resultou na proposição de um modelo fundamentado na premissa de que os comportamentos informacionais dos pesquisadores incluem estratégias que visam tanto assegurar o cumprimento de seu ofício de produção de conhecimentos, como também ampliar as chances de aceitação social de seu trabalho. Considerando a ênfase dessa concepção, as categorias de análise propostas foram reunidas em modelo que foi denominada Modelo 2C2S, identificando que os comportamentos informacionais podem se constituir como estratégias de Conhecimento, Conservação (2C), Sucessão ou Subversão (2S) no âmbito da estrutura de poder de uma área de pesquisa. Os conceitos que dão suporte a essa premissa tem origem na noção de campo científico de Bourdieu, cujo esquema sobre as relações entre “condições de existência”, “habitus”, “práticas e trabalhos” e “percepção e apreciação” foi adaptado para formar um esquema sobre as relações entre “condições de atuação científica”, “comportamentos informacionais”, “publicações científicas” e “reconhecimento científico”. Todos os elementos que constituem o Modelo 2C2S são exemplificados com trechos de entrevistas com os membros da ABC, ilustrando a adequação das categorias propostas para representar os relatos sobre os eventos empíricos estudados. Em “Quase letras”, são apresentados os procedimentos metodológicos utilizados para a coleta de dados das entrevistas e as ferramentas analíticas que estão sendo aplicadas aos depoimentos, partindo da estrutura de análise obtida com o Modelo 2C2S. A análise completa dos dados empíricos desta pesquisa está ainda em fase de elaboração.
With the adoption of different research strategies identified in the text as "Numbers", "Concepts" and "Quasi letters", this thesis aim to understand the relations between conditions of scientific performance, researchers informational behaviors, characteristics of scientific publications and determinants of international scientific recognition in the Brazilian context. In "Numbers", data from bibliometric research were presented to characterize the production and the impact of certain research areas in Brazil, considering the origin (national or foreign) of the journals in which the results were published, as well as international collaboration. The sample consisted of papers published by Brazilian researchers in 19 areas of knowledge published from 2002 to 2011, totaling 85,082 articles. For impact’s calculation, a standardized indicator called Relative Subfield Citedness (Rw) was used, adopting a window of 5 years to obtain measures evaluated in two distinct years: 2007 and 2012. Data of articles and citations were collected on the Web of Science database. From results obtained, it is remarkable that for most of the sub-areas presented, from 2002/2006 to 2007/2011, a performance improvement in the world rankings of production was observed. In relation to publications in national and foreign journals, a tendency to maintain the production distribution of subareas according to the origin of the periodical was noticed. In the context of impact, a lower Rw pattern was identified for Brazilian articles published in national journals in all subareas, compared with those published in foreign journals; in some subareas, even those published in foreign journals exceed the average global impact. Adopting another research strategy, a qualitative study was conducted based on interviews with members of the Brazilian Academy of Sciences (ABC), about their perceptions regarding the conditions of scientific activity in Brazil, as well as their own behaviors relative to the construction, communication and use of scientific information. In "Concepts", the search for a structure of analysis for the data of this qualitative research is reported, which resulted in the proposition of a model based on the premise that the informational behaviors of the researchers include strategies that aim both to ensure the fulfillment of their production of knowledge, as well as to increase the chances of social acceptance of their work. Considering the emphasis of this conception, the categories of analysis proposed were grouped in a model that was called Model 2C2S, identifying that informational behaviors can be constituted as Knowledge, Conservation (2C), Succession or Subversion (2S) strategies within the framework of Power of a research area. The concepts that support this premise are originated in Bourdieu's notion of the scientific field, whose scheme on the relations between "conditions of existence," "habitus," "practices and works," and "perception and appreciation" has been adapted to form a Schema on the relations between "conditions of scientific action", "information behaviors", "scientific publications" and "scientific recognition". All the elements that constitute the Model 2C2S are exemplified by excerpts from interviews with ABC members, illustrating the appropriateness of the categories, proposed to represent the reports on the empirical events studied. In "Quasi letters ", we present the methodological procedures used to collect interview data and the analytical tools that are being applied to the testimonies, starting from the structure of analysis obtained with the Model 2C2S. The complete analysis of the empirical data of this research is still being elaborated.

Abstract:
Systematic review of research manuscripts is a common procedure in which research studies pertaining a particular field or domain are classified and structured in a methodological way. This process involves, between other steps, an extensive review and consolidation of scientific metrics and attributes of the manuscripts, such as citations, type or venue of publication. The extraction and mapping of relevant publication data, evidently, is a very laborious task if performed manually. Automation of such systematic mapping steps intend to reduce the human effort required and therefore can potentially reduce the time required for this process.The objective of this thesis is to automate the data extraction and mapping steps when systematically reviewing studies. The manual process is replaced by novel graph modelling techniques for effective knowledge representation, as well as novel machine learning techniques that aim to learn these representations. This eventually automates this process by characterising the publications on the basis of certain sub-properties and qualities that give the reviewer a quick high-level overview of each research study. The final model is a concept learner that predicts these sub-properties which in addition addresses the inherent concept-drift of novel manuscripts over time. Different models were developed and explored in this research study for the development of concept learner.Results show that: (1) Graph reasoning techniques which leverage the expressive power in modern graph databases are very effective in capturing the extracted knowledge in a so-called knowledge graph, which allows us to form concepts that can be learned using standard machine learning techniques like logistic regression, decision trees and neural networks etc. (2) Neural network models and ensemble models outperformed other standard machine learning techniques like logistic regression and decision trees based on the evaluation metrics. (3) The concept learner is able to detect and avoid concept drift by retraining the model.
Systematisk granskning av forskningsmanuskript är en vanlig procedur där forskningsstudier inom ett visst område klassificeras och struktureras på ett metodologiskt sätt. Denna process innefattar en omfattande granskning och sammanförande av vetenskapliga mätvärden och attribut för manuskriptet, såsom citat, typ av manuskript eller publiceringsplats. Framställning och kartläggning av relevant publikationsdata är uppenbarligen en mycket mödosam uppgift om den utförs manuellt. Avsikten med automatiseringen av processen för denna typ av systematisk kartläggning är att minska den mänskliga ansträngningen, och den tid som krävs kan på så sätt minskas. Syftet med denna avhandling är att automatisera datautvinning och stegen för kartläggning vid systematisk granskning av studier. Den manuella processen ersätts av avancerade grafmodelleringstekniker för effektiv kunskapsrepresentation, liksom avancerade maskininlärningstekniker som syftar till att lära maskinen dessa representationer. Detta automatiserar så småningom denna process genom att karakterisera publikationerna beserat på vissa subjektiva egenskaper och kvaliter som ger granskaren en snabb god översikt över varje forskningsstudie. Den slutliga modellen är ett inlärningskoncept som förutsäger dessa subjektiva egenskaper och dessutom behandlar den inneboende konceptuella driften i manuskriptet över tiden. Olika modeller utvecklades och undersöktes i denna forskningsstudie för utvecklingen av inlärningskonceptet. Resultaten visar att: (1) Diagrammatiskt resonerande som uttnytjar moderna grafdatabaser är mycket effektiva för att fånga den framställda kunskapen i en så kallad kunskapsgraf, och gör det möjligt att vidareutveckla koncept som kan läras med hjälp av standard tekniker för maskininlärning. (2) Neurala nätverksmodeller och ensemblemodeller överträffade andra standard maskininlärningstekniker baserat på utvärderingsvärdena. (3) Inlärningskonceptet kan detektera och undvika konceptuell drift baserat på F1-poäng och omlärning av algoritmen.
