Presentamos el conjunto de instrumentos óseos del alero Las Tumanas (LT1) -Valle Fértil, San Juan- que representan ocupaciones humanas de comunidades productoras de baja intensidad del Holoceno tardío. Los objetivos principales de esta contribución son determinar las actividades realizadas en el alero relacionadas con la construcción, uso y descarte de instrumentos óseos y discutir los alcances interpretativos en una escala macroregional. Determinamos las categorías taxonómicas y anatómicas de los soportes óseos y las relacionamos con la disponibilidad de los recursos faunísticos a partir del conjunto óseo registrado en el alero. También analizamos la distribución espacial de los instrumentos defi niendo dos sectores de actividad relacionados con el uso y descarte. Finalmente postulamos una relación entre las características de la tecnología ósea con funciones relacionadas con la manipulación de materias blandas y actividades de punzar y coser.

In this study, the first-year chemistry laboratory course was renewed and made more intensive, three weeks course. Students’ experiences of the renewed course were examined by analyzing their learning diaries which they were encouraged to keep during the whole course. The purpose of this study was to find out how the intense coursework affects students’ emotions and learning experiences. Thus, the learning diaries were analyzed in order to find out different emotions that students experienced during the course. These emotions were then classified and represented using a model based on a two-dimensional emotion theory. Diversity of students’ emotions during the course gave us important information how emotions influenced on student’s learning and achievement. For teacher it is valuable to understand and deal with the emotions experienced by students while planning and carrying out the laboratory course. This enables not only higher quality teaching, but also more positive learning outcomes for students regarding their chemistry laboratory studies. FULL TEXT IN FINNISH.

Diversos estudios ponen de manifiesto que la sociedad occidental está sometida a una anormal velocidad. Paradójicamente, disponemos de numerosas herramientas para gestionar y economizar nuestro tiempo y, sin embargo, cada vez carecemos más de él. Ante este clima de vertiginosidad surgen movimientos que pretenden rebelarse contra la aceleración, como el denominado «movimiento por la lentitud». El ámbito educativo no es ajeno a esta problemática y también desde él surgen iniciativas y propuestas pedagógicas que tratan de combatir este acelerado ritmo desde la escuela, como la denominada «educación lenta». A partir del estudio realizado en Italia sobre la Pedagogia della Lumaca, se pretende desarrollar el pensamiento pedagógico de su ideólogo, el maestro Gianfranco Zavalloni, a través de la identificación de los que fueron los referentes para la configuración de su propuesta educativa, conocida en España como la «Pedagogía del Caracol». A su vez, se tratará de desvelar cómo podría ser definida tal propuesta, identificar los principios sobre los que se sustentaría, y enunciar algunas de sus finalidades educativas. Tal estudio se ha llevado a cabo desde una metodología de corte cualitativo, a través de técnicas, como la revisión bibliográfica y documental de las obras del maestro Zavalloni, así como de diversas entrevistas a su entorno personal y profesional. A la luz de los datos obtenidos, cabe afirmar que, más que un enfoque, un modelo pedagógico o una metodología, la Pedagogía del Caracol resulta ser una corriente pedagógica a partir de la cual se puede configurar un método educativo desde una mirada paidocéntrica. La Pedagogía del Caracol, al igual que la educación lenta, tendría entre sus finalidades enmarcar a aquellas pedagogías que valorizan el tiempo en la educación y persiguen dotar a los niños y a las niñas de las habilidades y los valores necesarios para ser dueños y dueñas de su tiempo.

This study explores how students deal with material resources in their peer interaction when working in pairs in an open-ended problem-solving task. The productive use of material resources can be expected to support successful peer work. However, research into social phenomena in peer interaction is needed in order to identify and describe productive and less productive forms of dealing with material resources as students participate in open-ended problem-solving tasks. Consequently, this explorative study responds to this research need. Based on multimodal data, including video recordings, transcribed talk and the written contributions from four pairs of Year 7 students aged 12-13 years, the analysis focuses on different ways in which students deal with material resources while negotiating their participation as they respond to the task. The findings indicate that aspects of participation are a key factor for describing productive and less productive ways of dealing with material resources by the student pairs. Foregrounding aspects of participation for an increased awareness of potential obstacles to student-centred work is among this study’s contributions for classroom practice and theory development.

Syftet med artikeln är att lyfta fram om, och i sådant fall på vilka sätt, en specifik strukturell modell kan utgöra stöd när elever utforskar matematiska strukturer i ekvationer. Artikeln bygger på en empirisk forskningsstudie där elever utforskade matematiska strukturer med stöd av modellen, vilken är avsedd att visualisera strukturer. Lärare och forskare arbetade i en kollaborativ och intervenerande studie i iterativa processer. Sammantaget 149 elever från grundskolans årskurser 3, 8 och 9 deltog i filmade forskningslektioner utifrån forskningsansatsen learning study. Lektionerna designades med inspiration från ramverket lärandeverksamhet och eleverna utmanades i ett teoretiskt arbete. Analysen utfördes utifrån tematisk ansats och två kvalitativt skilda kärnteman identifierades: Formulär respektive Lärandemodell. I analysen framträdde att undervisningen behöver vara tillräckligt utmanande för att eleverna ska finna modellen meningsfull. Undervisningen behöver möjliggöra för eleverna att urskilja relationer mellan alla tal i en ekvation, där relationerna kan beskrivas som en del-helhetsstruktur. A model to support exploring equations The aim of the article is to highlight whether, and if so in what ways, a selected model can constitute support when students explore mathematical structures in equations. The article is based on an empirical research study where students explored mathematical structures with support by the model, which is intended to visualize structures. Teachers and researchers worked in a collaborative and interventional study in iterative processes. A total of 149 students from compulsory school grades 3, 8 and 9 participated in video recorded research lessons based on the research approach learning study. The lessons were designed with inspiration from the framework of learning activity and the students were challenged in a theoretical work. The analysis was performed on the basis of a thematic approach and two qualitatively different core themes were identified: Template respectively Learning model. In the analysis, it emerged that the teaching has to be challenging enough for the students to find the model meaningful. The teaching needs to enable students to discern relationships between all numbers in an equation, where the relationships can be described as a part-whole structure.

En viktig målsättning för naturvetenskaplig undervisning är att utveckla förmågan att formulera undersökningsbara frågor. Syftet med den här studien är att undersöka hur undervisning som utformats med hjälp av metoden Question Formulation Technique (QFT) kan stödja utveckling av elevers förmåga att formulera naturvetenskapligt undersökningsbara frågor. QFT är en modell för att utveckla elevers förmåga att formulera och värdera sina egna frågor i allmänhet. I studien prövas QFT i en svensk skolkontext och inom ramen för naturvetenskaplig undervisning. Studien genomfördes som en interventionsstudie i gymnasieskolan och inom ramen för kursen Gymnasiearbete. I kursen ska eleverna genomföra en egen naturvetenskaplig undersökning. QFT användes för att utforma undervisning som del av introduktionen till kursen. Data består av videoinspelningar av elevsamtal från undervisning som har analyserats utifrån ett pragmatiskt ramverk med organiserande syften och praktisk epistemologisk analys. Resultaten visar vilka närliggande syften som etableras i elevernas samtal om undersökningsbara frågor i undervisningen: (A) att producera så många frågor som möjligt, (B) att bedöma vilka frågor som är mest relevanta, (C) att kategorisera frågor, (D) att hitta och specificera ett undersökningsobjekt och (E) att planera för att genomföra en undersökning. Slutsatsen är att QFT kan fungera som stöd för lärares planering av undervisning om naturvetenskapligt undersökningsbara frågor under förutsättning att läraren aktivt stödjer eleverna i att uppmärksamma centrala kvaliteter avseende undersökningsbarhet och genom att binda samman närliggande syften med det övergripande syftet. In English An important goal for science education is to develop students’ ability to formulate questions of inquiry. The aim of this study is to investigate if science teaching designed from the method “Question Formulation Technique” (QFT) can support the development of this ability. QFT is a model for developing students' ability to phrase and evaluate questions in general which has been developed in a US context. In this study QFT is used in a Swedish context and within upper secondary school science education. The study is an intervention study where QFT was used as part of the introduction to Diploma work in the final year of upper secondary school. During the diploma work students are expected to conduct their own scientific investigations. The data consists of video recordings of student conversations while working with the formulation of questions for inquiry as part of a research lesson designed using QFT. Data was analyzed using a pragmatic approach of combining practical epistemological analysis (PEA) and organising purposes. The results show that five proximate purposes were established in the student conversations while the students engaged in formulating and refining questions of inquiry based on the QFT model. The five proximate purposes were: (A) to produce as many questions as possible, (B) to assess which questions are most relevant, (C) to categorize questions, (D) to find and specify the object of inquiry and (E) plan to conduct an inquiry. In conclusion, QFT can support the planning of teaching in relation to the ultimate purpose regarding how to formulate and refine questions of inquiry provided that the teacher actively participates to support students in connecting the established proximate purposes with the ultimate purpose.

This thesis is an exploration of print within contemporary art that has been motivated by a perceived lack of current theoretical and critical dialogue concerning print practice. Beginning with a discussion of writings of critic Walter Benjamin , specifically the ‘Work of Art in the Age of Mechanical Reproduction’ I will highlight the nuanced and paradoxical aspects of reproducible print in an age of visual saturation. In the presence of rapidly renewed technologies and digital culture, this complicates how one experiences print in the world and allows older technologies and practice to escape critique. By drawing on French philosopher Gilles Deleuze’s theoretical frameworks of the event and series, I will synthesize these paradoxes and examine printed works beyond their reproducibility and linear timeline. I will argue for print media’s multifaceted material configurations by making connections between modern and contemporary modes of print. Lastly, I will explore these relationships within my own practice, and posit that the understanding of these varied medias will further enrich our understanding of print in contemporary art.
