Two novel europium(III) complexes, a monomer and a homodimer, with 1-(4-chlorophenyl)-4,4,4-trifluoro-1,3-butanedione (Hcbtfa) and 5-chloro-1,10-phenanthroline (cphen) ligands, formulated as [Eu(cbtfa)3(cphen)] and [Eu2(cbtfa)4(cphen)2(CH3O)2], have been synthesized. Their structures have been elucidated by X-ray diffraction and their absorption and emission properties have been studied in the solid state. The experimental data has then been used to test the recently released LUMPAC software, a promising tool which can facilitate the design of more efficient lanthanide light-conversion molecular devices by combining ground state geometry, excited state energy, and luminescent properties calculations.

Adolescent idiopathic scoliosis Lenke I dengan pola kurva mayor pada kurva thorakal (main thoracic), dengan kurva proximal thoracic dan thoracolumbar/lumbar sebagai kurva minor non struktural. Instrumentasi dan fusi hanya pada kurva thorakal dianjurkan. Pada literatur dijelaskan bahwa koreksi spontan kurva lumbal terjadi sebagai kompensasi untuk menyeimbangkan kurva thorakal setelah dilakukannya fusi thorakal selektif. Lumbal modifier dibagi menjadi 3 grup, pemilihan terapi operatif bergantung pada tipe lumbal modifier. Penelitian ini merupakan suatu analisis observational pada 35 pasien adolescent idiopathic scoliosis Lenke I paska operasi koreksi deformitas dan instrumentasi posterior. evaluasi menggunakan X ray sebelum dan setelah operasi untuk penentuan tipe lumbal modifier, besarnya koreksi kurva thorakal dan penilaian koreksi spontan kurva lumbal, kemudian dilakukan uji korelasi terhadap data yang didapat. Besarnya koreksi kurva thorakal terhadap koreksi spontan kurva lumbal paska operasi memiliki nilai signifikansi (Sig) = 0,000 < 0,05 dan besarnya koreksi kurva thorakal memiliki nilai koefisien regresi lebih besar bila dibandingkan dengan lumbal modifier terhadap koreksi spontan kurva lumbal paska operasi (variabel besar koreksi kurva thorakal (X1) = 0,764, Lumbal modifier (X2) = 0,092). Besarnya koreksi kurva thorakal berpengaruh signifikan terhadap koreksi spontan kurva lumbal paska operasi dan besarnya koreksi kurva thorakal yang paling dominan dalam mempengaruhi koreksi spontan kurva lumbal dibandingkan dengan lumbal modifier.Kata kunci : Adolescent idiopathic scoliosis, Lumbal modifier, kurva thorakal Adolescent idiopathic scoliosis Lenke I, main thoracic curve pattern has the major curve, with the proximal thoracic and thoracolumbar/lumbar being non structural minor curves. Thus, instrumentation and fusion of the main thoracic region alone is recommended. In the literature it is said that the lumbar curve spontaneously corrects to balance the thoracic curve after selective thoracic fusion. Most authors assumed a mechanism whereby improvement of the lumbar curve occurred through counterbalancing the surgical correction of the thoracic curve. The lumbar curve divided in three subgroups: lumbar modifier A, B and C. The selection of specific operative treatments depends on this modifier. This study was an observational analysis in 35 adolescent idiopathic scoliosis Lenke I patients after correction and posterior instrumentation surgery. Evaluation using X-rays before and after surgery to determine the type of lumbar modifier, the magnitude of the main thoracic curve and assessment of spontaneous lumbar curve correction, then correlation test obtained. The magnitude of main thoracic curve correction to the spontaneous lumbar curve correction has a significance value (Sig) = 0.000 < 0.05 and the magnitude of main thoracic curve correction has a greater regression coefficient than the lumbar modifier for spontaneous lumbar curve correction (large correction variable thoracic curve (X1) = 0.764, Lumbal modifier (X2) = 0.092). The magnitude of main thoracic curve correction has a significant effect on the spontaneous lumbar curve correction and the magnitude of main thoracic curve correction is most dominant factor to influence spontaneous lumbar curve correction compared to the lumbar modifier.Keywords: Adolescent idiopathic scoliosis, Lumbar modifier, main thoracic

Spinal stiffness and mobility assessments vary between clinical and research settings, potentially hindering the understanding and treatment of low back pain. A total of 71 healthy participants were evaluated using 2 clinical assessments (posteroanterior spring and passive intervertebral motion) and 2 quantitative measures: lumped mechanical stiffness of the lumbar spine and local tissue stiffness (lumbar erector spinae and supraspinous ligament) measured via myotonometry. The authors hypothesized that clinical, mechanical, and local tissue measures would be correlated, that clinical tests would not alter mechanical stiffness, and that males would demonstrate greater lumbar stiffness than females. Clinical, lumped mechanical, and tissue stiffness were not correlated; however, gradings from the posteroanterior spring and passive intervertebral motion tests were positively correlated with each other. Clinical assessments had no effect on lumped mechanical stiffness. The males had greater lumped mechanical and lumbar erector spinae stiffness compared with the females. The lack of correlation between clinical, tissue, and lumped mechanical measures of spinal stiffness indicates that the use of the term “stiffness” by clinicians may require reevaluation; clinicians should be confident that they are not altering mechanical stiffness of the spine through segmental mobility assessments; and greater resting lumbar erector stiffness in males suggests that sex should be considered in the assessment and treatment of the low back.

AbstractThe incidence of spinal trauma in the world is 0.019-0.088% per year. However, the epidemiological data from each country varies according to the specificities of each country. Until now, there have been no reports of epidemiological research for vertebral trauma in Indonesia. This research is a descriptive analytic study. The sample of this study were all patients with vertebral fractures who entered the Dr. Soetomo Hospital in 2013-2017. The data were obtained through medical records and electronic data in hospital databases. The data are displayed in tables and graphs and comparative analysis of variables is carried out. Based on data from 2014-2017, there were a total of 442 patients with vertebral fractures, with male and female ratio of 3.3: 1. The mean age of patients was 43.6 year. The causes of vertebral fractures are due to fall from altitude (38%), traffic accidents (34%), and direct impact / hit burden (10%). Based on fracture level, most fractures were at the lumbar level (153 patients, 34,6%). At the lumbar level, the most fracture subtypes were type A with a percentage of 91.5% and the most mechanism of injury was due to falling from a height. Based on the fracture subtype, type A (compression or burst) fracture is the most common type of fracture. Lumbar vertebral fracture is the most fractured in vertebral fractures. The most common cause of fracture in the vertebrae is trauma with great energy due to falling from a height.Keywords: Epidemiology, vertebral fractures, spinal traumaCorrespondence to : dr.donnypermana@gmail.com Abstrak Insiden trauma spinal di dunia tercatat sebesar 0,019% hingga 0,088% per tahun, namun data epidemiologi dari masing-masing negara adalah berbeda-beda, sesuai dengan kekhususan dari masing-masing negara.

Introduction: The purpose of this study is to retrospectively report the results of scoliosis patients who underwent chiropractic therapy and to evaluate their outcome by looking at the potential to alter the natural progression of scoliosis after therapy. Methods: Retrospective data collection was conducted at a private chiropractic centre in Kuala Lumpur. The data was collected from patients between the ages of 16 to 19 years old. A total of eight patients with 14 scoliotic curvatures (six thoracic, six lumbar and two thoracolumbar), who met the inclusion criteria, were selected as subjects for this study. All subjects received the same chiropractic therapy program. The outcome of the therapy was assessed by measuring the Cobb’s angle on the erect spine as captured on an x-ray. The Cobb’s angle was measured at the first presentation (to establish a baseline) after 6 and 24 months of therapy. Results: The mean baseline Cobb’s angle for thoracic, lumbar and thoracolumbar scoliosis were 30.7o ± 19.4o , 31.7o ± 12.3o and 25.0o ± 18.4o respectively. After 24 months of chiropractic therapy, there was no discernible effect on the magnitude of the Cobb’s angles on the subjects overall. Conclusion: Our study showed no significant reduction in spine curvature in patients with scoliosis using chiropractic therapy after 24 months.

The article discusses the development of an educational model intended to support teachers’ professional development in science education. In this research and development project, LumaLähetit, pre-service teachers, in-service teachers, and teacher educators formed teams to collaboratively plan teaching and produce material for inquiry-based and integrative science instruction in primary schools. The results are based on three design cycles of the model. Thus far, ten schools, 24 in-service teachers, 30 pre-service teachers, and 560 pupils have participated. The results, which are based on the qualitative content analysis of participants’ open answers to a questionnaire, indicate that the developed collaborative model for science education supported preservice teachers and in-service teachers’ professional development in many ways. Several processes mediating the embodiment of the designed model were identified, especially during the second or third design cycles. Participants reflected on theory and practice. They experienced increased knowledge about inquiry and integrative approaches, collaborated in teams to some extent, and found this to be supportive during the project. Also, pre-service teachers appreciated the opportunity to teach in the schools. In general, careful goal setting, collaboration between the participants, and guidance by teacher educators during the initiation of the project were found to be crucial to the further success of the project. The results highlight a need for further research in order to better meet to the challenges of team teaching, inquiry-based instruction, and integrative teaching. The designed model was developed between the cycles and must be further developed in the future, especially in terms of supporting collaboration and clarifying theoretical concepts during the project.

The aim of the study was to examine how different book series support teacher in the pupil assessment. The focus of the study was on the demand of many-sidedness and continuity of assessment expressed in the curriculum. All materials in three different book series made for 2nd grade were analyzed. All the assessment instructions were collected from the materials and they were quantitatively examined based on their amount and location. The instructions were divided in two groups based on qualitative analysis: hands-on instructions and pedagogical instructions. Based on results Finnish textbook series follow well the concrete aims set out in the curriculum (Opetushallitus, 2004). Instead it is not so straightforward to interpret many-sidedness and continuity because the concepts can be defined in many ways. However, it can be noted that the assessment emphasizes one-sided traditional assessment: teacher gives the assessment, the aim of the assessment is to collect information, the target of the assessment is the learning result, and the method for assessment is quantitative tests. Newer forms of assessment could be found from the researched materials but they didn’t appear very systematically. When researching the continuity of the assessment it was found out that the materials guided teachers to make assessments several times during the semester. The assessment was suggested to perform at the end of the study module. The materials didn’t guide systematically to assess during the study module. FULL TEXT IN FINNISH

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.

A Chemistry concept inventory has been developed for assessing students learning and identifying the alternative conceptions that students may have in general chemistry. The conceptions in question are assumed to be mainly learned in school and to a less degree in student’s daily life. The inventory therefore aims at functioning as a tool for adjusting teaching practices in chemistry. The concept inventory presented here is mainly aimed at assessing students learning during general chemistry courses. The inventory has been administered and evaluated using statistical tests, focusing on both item analysis and on the entire test. The results indicate that the concept inventory is a reliable and discriminating tool in the present context.

This study aimed to investigate how teachers’ certification status, experience in instruction, and teachers’ efficacy beliefs for teaching lower secondary students in mathematics are related to differentiated instruction practices. A total of 42 mathematics teachers and 27 special education teachers answered an electronic questionnaire regarding mathematics teaching efficacy beliefs and their frequency of use of differentiation practices. The results indicated that teachers’ efficacy beliefs were related to differentiation in content, flexible examination models, homework support, and co-teaching. Neither certification status nor teacher experience in instruction was related to the frequency of use of differentiation practices. As teacher efficacy beliefs seem to have an effect on the use of differentiation practices, and especially on co-teaching, it should be important for teacher education to focus on developing pre-service teachers’ efficacy beliefs as well as implementing a strong collaboration between different teacher groups.

The article examines the opportunities and challenges for the use of ICT in science education in the light of science teachers’ Technological Pedagogical Content Knowledge (TPACK). Some of the variables that have been studied with regard to TPACK framework in science classrooms (such as teachers' self-efficacy, gender, teaching experience, teachers’ believes, etc.) are reviewed, also variations of TPACK framework specific for science education are elaborated. In conclusion some of the aspects of TPACK in science education that need to be addressed in future are indicated, e.g. the development of subject specific ICT-based resources and e-learning platforms; training to develop science teachers’ integrated skills for the implementation of ICT in their subject teaching; the importance of continuous encouraging of science teachers’ for their participation in in-service training related to the use of ICT; and the examination of the role of science teachers’ TPACK in developing of students’ 21st century trans-disciplinary skills.

VASI (views about the scientific inquiry) questionnaire was applied to a sample of 149 7th grade students. When assessing each aspect of VASI, pupils' views were categorized into one of four categories: informed, mixed, naive, and unclear. According to the diagnostical test, 7th grade students did not possess informed conceptions of NOS in average, while certain questions were better understood. E. g., question #4 which measured the possession of the VASI aspect "Data does not equal evidence" was relatively well understood indicating that Finnish students had good reading ability and logical deduction skills without prior explicit teaching of VASI concepts.

Abstract: The examination of cerebrospinal fluid obtained by a lumbar puncture is important in the diagnosis of CNS infection. There have been no reports of refusals of lumbar punctures in Manado. This study is a descriptive preliminary using interviews and questionnaires. The subjects were all patients or families of patients in the inpatient unit at the Department of Neurology BLU. Prof. Dr. R. D. Kandou Manado in November 2012. The results showed that of the total number of 60 respondents, 27 (45%) under advice, agreed to undergo lumbar punctures; 30 (50%) refused, and 3 (5%) were not able to decide and thus abstained. While 93.3% of respondents knew the definition and indications of lumbar puncture, 86.7% refused eventhough they knew that the lumbar puncture procedure was important in the management of the disease; 86.7% assumed that the lumbar puncture was a dangerous procedure; 80% felt unsure enough to refuse; and 86.7% were afraid to have the lumbar puncture procedure done. All respondents knew that lumbar puncture had complications. Conclusion: nearly all respondents who refused knew that the lumbar puncture procedure is important in the management of the disease, yet they assumed the lumbar puncture was dangerous, uncomfortable, and felt fearful. Keywords: lumbar puncture, neurology, refusal description, society.

The first stage of labor starts from the onset of cervical dilatation and divided into latent and active phases. The latent phase is a more prolonged phase of labor, which allows various interventions performed. Interventions and the latent phase's length may lead to anxiety and restlessness, which might contribute to prolonged labor when experienced by women in labor. A combination of the Zilgrei method and lumbar massage used to reduce labor pain. This method combines movement, change of position, breathing exercise, and the light massage performed since the first stage of labor. It expected that the work of interrelated pelvic muscles becomes harmonized; hence, the cervix will be softer, and the uterine muscles may push the fetus towards the birth canal. This study aimed to determine the effect of the Zilgrei method and lumbar massage combination on the latent phase of the first stage of labor progress in primigravida. It is a quantitative quasi-experimental study on 66 women who underwent the latent phase of the first stage of labor in independent practice of midwife the work area of Citarip Public Health Center during May–July 2019, who were divided equally into control and intervention groups. The statistical analysis used was univariate and bivariate analyses with an independent t test. The mean duration of labor in the latent phase of the first stage of labor in the control group and intervention group was 368 minutes and 307 minutes, respectively, with a difference of 61 minutes (p=0.002). Therefore, the Zilgrei method and lumbar massage combination significantly affect labor progress in the latent phase of the first stage of labor in primigravida. PENGARUH KOMBINASI METODE ZILGREI DAN PEMIJATAN LUMBAL TERHADAP PROSES KEMAJUAN PERSALINAN PADA PRIMIGRAVIDAKala I persalinan merupakan tahap serviks terbuka yang terdiri atas fase laten dan fase aktif. Fase laten mempunyai durasi persalinan lebih panjang sehingga memungkinkan banyak intervensi. Intervensi dan lama fase laten dapat menimbulkan kecemasan dan kegelisahan, apabila dialami ibu in partu dapat menjadi faktor persalinan lama. Kombinasi Metode Zilgrei dan pemijatan lumbal menjadi metode mengurangi rasa nyeri persalinan yang menggabungkan gerakan, perubahan posisi, latihan pernapasan, dan pijatan ringan yang dipersiapkan sejak kala I persalinan. Diharapkan kerja otot panggul saling berkaitan menjadi selaras sehingga serviks tidak kaku dan terdapat potensi otot rahim mendorong janin menuju jalan lahir. Tujuan penelitian ini mengetahui pengaruh kombinasi Metode Zilgrei dan pemijatan lumbal terhadap kemajuan proses persalinan kala I fase laten pada primigravida. Penelitian ini merupakan penelitian kuasi eksperimental kuantitatif pada 66 wanita yang menjalani fase laten persalinan kala I di bidan praktik mandiri (BPM) wilayah kerja Puskesmas Citarip periode Mei–Juli 2019 yang dibagi rata menjadi kelompok kontrol dan intervensi. Analisis statistik menggunakan analisis univariat dan bivariat dengan uji t independen. Durasi persalinan kala I fase laten rerata kelompok kontrol dan intervensi adalah 368 menit dan 307 menit masing-masing dengan selisih waktu 61 menit (p=0.002). Simpulan. kombinasi Metode Zilgrei dan pemijatan lumbal berpengaruh terhadap kemajuan proses persalinan kala I fase laten pada primigravida.

Laborationer har lång tradition i fysikundervisningen och det finns många klassiska skolexperiment. Samtidigt påverkas laborationsundervisningen av reformer och teknikutveckling. I denna studie fick lärare på tre gymnasieskolor diskutera sin laborationsundervisning. Analysen baseras på händelselogik, där handling ses som intentionell och styrs av determinanterna: målsättning, förmåga, plikt och möjligheter. Studien ger insikt i hur olika faktorer påverkar lärares laborationsundervisning, och hur klassiska laborationer i fysikundervisningen både kan ha en given plats och utmanas av nya förutsättningar. Resultaten antyder att praxis och tradition är starkare påverkansfaktorer än styrdokument i lärares utformning av laborationsundervisningen, vilket delvis kan relateras till en avsaknad av fortbildning. In English Experiments have a long tradition in physics teaching and there are many examples of classical school experiments. At the same time laboratory teaching is affected by curriculum changes and technological development. In this study experienced teachers at three different upper secondary schools discuss their laboratory teaching. The analysis is based on the logic of events. The study provides insight into factors affecting teachers’ teaching and how classical experiments are adapted and challenged by new conditions. The results indicate that tradition is a stronger factor of influence than policy documents, in particular when very limited time is allowed for professional development. FULL TEXT IN SWEDISH.

The aim of this study is to find out whether there is a connection between teacher’s request and guidance for written explanation and third-graders’ achievements in solving a non-standard problem. Pupils’ task was to solve a simplified arithmagon and to explain their solution. The lessons of seven teachers were recorded and their actions were examined and categorized during a problem-solving lesson. Also pupils’ solutions were checked and classified. The teacher’s behavior seems to have a crucial role in the quality of pupils’ written explanations. The third-graders had difficulties in writing their reasoning for solving the problem.

This paper presents a meta-analysis of the literature on parental engagement with children’s formal and informal science, technology, engineering and mathematics (STEM) education. Five recurrent themes have emerged from the literature review: The challenges of supporting parents with children’s STEM education; STEM education as a bridge between school and family; STEM education as a gateway for children’s future economic success; STEM education as a vehicle for promoting student communication skills; and, the role of hands-on inquiry-based activities in enhancing student engagement. We also outline some international informal STEM education initiatives, their scope, challenges and impact.

This mixed-methods case study examines parental motivation for participation in a Canadian university-based STEM outreach event. Parents responded to a post-event questionnaire that was followed by individual interviews. The quantitative part revealed how and why parents engaged with their children’s STEM education. Surprisingly, neither university admission requirements nor STEM-related job opportunities were top motivating factors. The qualitative part indicated that some parents found it challenging to connect their children’s learning experience in school with the government-mandated curriculum or with their own experiences. Most interviewees were satisfied with their children’s STEM education and considered family support crucial in this process.

This case study focuses on teachers’ actions during problem-solving lessons. The aim of this study was to find out how teachers guide students during mathematics problem-solving lessons: What kinds of questions do teachers ask? How do students arrive at solutions to problems? The dataset contained videotaped fourth-grade math lessons in which students solved a mathematical problem. The research reveals that teachers can guide students in numerous ways and possibly in ways that prevent students from searching for their own solution strategies. For this reason, problem-solving exercises alone are not sufficient for teaching students problem solving, as teachers must also be instructed in how to properly guide students. In the conclusion section, we discuss the types of questions that enable teachers to promote active learning in students, which should be the goal of instruction according to the constructive learning theory.

Matematiikan opetuksessa voidaan käyttää niin sanottua vertailumenetelmää, jossa oppilaat tuottavat yhteen tehtävään useamman eri ratkaisutavan tai ne näytetään heille. Tämän jälkeen ratkaisutavoista keskustellaan vertaillen. Tavoitteena on lisätä oppilaiden matemaattista joustavuutta. Tässä fenomenografisessa tutkimuksessa selvitetään, millaisia käsityksiä 25 suomalaisella matematiikan opettajalla ja opettajaopiskelijalla on vertailumenetelmästä heidän tutustuttuaan siihen ensimmäistä kertaa. Osallistujat toivat esiin erilaisia hyötyjä: oppilaat voisivat oppia useita tapoja nähdä asioita, löytää itselleen sopivan ratkaisumenetelmän, opettajasta tulisikin valmentaja ja keskustelu lisääntyisi. Tutkimukseen osallistuneet olivat huolissaan, että oppilaita ei välttämättä kiinnosta useiden ratkaisutapojen käyttö, heillä ei ole valmiuksia siihen tai menetelmä vaatisi opettajalta liikaa. In English In mathematics teaching, the comparison method means that students produce or are shown multiple methods for the same problem. Following that, the methods are compared in discussion. The goal is to develop the students’ mathematical flexibility. In this study, phenomenography was used to discover the conceptions of 25 Finnish mathematics teachers and teacher students after they were familiarized with the comparison method for the first time. Participants brought up a wide variety of benefits of using the comparison method: students could learn to see things from different perspectives, they could discover the method that is most suitable for them, and the teacher would become more like a coach; discussion would also increase. Participants worried that students may not be interested in using multiple solving methods, students may not possess the skills necessary for it, or the method could be too demanding on the teacher. FULL TEXT IN FINNISH.

Tässä tutkimuksessa tarkasteltiin 1. ja 4. luokan matematiikan oppikirjojen multimodaalista tekstiympäristöä eli moninaisten semioottisten resurssien käyttöä, joka on keskeistä matematiikan oppimisessa. Tavoitteena oli selvittää, 1) millaisia semioottisia resursseja oppikirjoissa on sekä luettavaksi annettuna (ts. tekstien tulkinnassa) että tehtäviksi annettuna (ts. tehtävien tekstien tuottamisessa), 2) miten niitä hyödynnetään merkitysten luomisessa ja 3) kuinka monipuolisesti semioottisia resursseja hyödynnetään oppikirjoissa. Tutkimuksen lähestymistapana on monimenetelmä (mixed-methods). Aluksi tarkastelin aineistojen diskurssia yleisellä tasolla soveltaen metafunktiota ja aikaisempia tutkimuksia. Sen jälkeen erittelin aineiston sisältöjä määrällisesti: onko kyseessä tekstien tulkinta vai tuottaminen ja mitä semioottisia resursseja käytetään. Lopuksi tarkastelin eriteltyjen aineistojen diskurssia. Tutkimustulokset osoittavat, että multimodaalisuuden näkökulmasta monipuolisia tekstiympäristöjä huomioidaan hyvin vähän tutkituissa oppikirjoissa. Matematiikan symbolikieli on selkeästi dominoiva erityisesti tekstien tuottamisessa. Kaikissa oppikirjoissa erilaisia semioottisia resursseja hyödynnetään enimmäkseen vain oppilaan luku- ja laskutaitojen perusteella sekä matematiikan opetettavien sisältöalueiden kannalta. Oppilaan monilukutaidon kannalta matematiikan oppikirjojen tekstiympäristö voisi olla monipuolisempi: oppilaalle voitaisiin tarjota enemmän multimodaalista luettavaa ja tuotettavaa. In English This study investigated first- and fourth-grade mathematics textbooks’ multimodal text environment. It aimed to discover 1) what semiotic resources are utilised for interpreting and producing texts, 2) how they are used for meaning-making and 3) how diversely. The inquiry strategy was mixed-methods. First, I analysed discourse of the research data generally using metafunction and previous research. Then, I quantified each semiotic resource’s distribution in terms of text interpretation and production and types of semiotic resources. Finally, I analysed discourse of each quantified data. Research findings demonstrate that from a multimodal perspective, diverse textual environment is barely paid attention to. The symbolic language is dominant, especially to text production. In all textbooks, semiotic resources are used mainly on the basis of student’s literacy and numeracy and to-be-leant mathematics contents. In favour of a student’s multiliteracies, mathematics textbooks’ text environment should be more diverse: offer more multimodal text interpretation and production. FULL TEXT IN FINNISH.

Science competitions, such as the International Biology Olympiad, are non-formal education targeted to upper secondary school students with high abilities. However, there is little knowledge about what is the relevance of training for a science competition. In this study, Finnish Biology Olympiad training participants were researched in the context of relevance of science education. In total, 28 students filled in questionnaires and participated in interviews. It was found out that the students experienced the training to be especially individually relevant for them, and there was no significant difference between genders. Based on the results, vocational and societal topics should be taken into more account in designing Olympiad trainings.

This article examines what key aspects primary teachers highlight when they describe their use of out of school learning in the science subjects. The empirical study is made in the form of a semi-structured interview with primary teachers (N=15). Compared to earlier research in the area the results highlight the importance of clear learning aims for the outdoor sequence. The results show that teachers view outdoor education as an opportunity to study nature "for real", which, according to teachers, increases the interest of the children. As aspects that obstruct outdoor teaching, teachers mainly describe different organizational-economic aspects. In their description of the learning content in the outdoor education, teachers mainly talk about the students’ interest (affective motivations) and the concrete activity or act (process-oriented motivations). The scientific subject knowledge is limited in the teachers’ descriptions.

In this case study, we describe an inquiry-based approach to enhancing tuition in chemistry by taking student teachers out of the lab and into nature. We used video observation and interviews to gain insight into student teachers’ expectations and experiences of such fieldwork. Through thematic analysis, we found that the participants perceived the approach as individually relevant and worthy of integrating as a teaching method in future practice. Further, we discussed challenges presented by outdoor chemistry and ways to overcome these. Overall, we show that fieldwork in chemistry contributed to a better understanding of chemistry as an integral part of nature.

Non-formal science education means goal-oriented learning outside of school. The use of out of school learning environments (e.g. science camps) has been found to increase motivation and interest in natural sciences. In this study, the relevance of non-formal science education in science camps has been analyzed from the perspectives of children and families, which has not been studied before. The analysis of relevance has been based on the relevance theory developed by Stuckey, Hofstein, Mamlok-Naaman & Eilks in 2013. The study focuses on the 46 science camps organized by the University of Helsinki LUMA Centre in the years 2015 and 2016, involving more than 900 schoolchildren and some of their parents (N=124). The study examined also the impact of children’s gender and children’s earlier interest in science on the relevance of chemistry related science camps. Survey and theme interview were both used as research methods. The results of the survey show that non-formal science education in science camps is relevant according to both the children and the families, mainly at the level of individual relevance, with emphasis on present and intrinsic dimensions of relevance. The tasks related to the camp themes, for example in chemistry camps, experimental work in the laboratory, and friends made in the science camps are the most relevant for children. The chemistry science camps are individually most relevant to those children who didn’t have much earlier interest in chemistry. Boys are more confident about their own interests at the individual relevance level than girls. At the level of societal relevance, boys are more focused on present-day relevance than girls when girls also consider the future. The levels of societal and vocational relevance were only slightly visible in the answers of the survey. However, based on theme interviews, camps were considered as relevant for all relevance levels of the relevance theory. The results of this research can be utilized in the development of out of school learning environments, especially in the development of science camps and in further research.

Based on Dewey’s theory of art, aesthetics, and experiences and photographer Barnbaums’ writing about expanded perception through photography, we conducted a one-day experimental mathematics education unit. Using photography in outdoor conditions had a positive impact on teacher students’ perception of the use of photography for teaching mathematics. To study the changes in students’ visual attention deeper, we used gaze-tracking to analyse one student’s visual attention when walking outdoors after the activity. The gaze data indicated that more visual attention was given to objects he had photographed or discussed during the group activity in comparison to other objects.

The objective of this study is to understand how the perception of teachers might change after they participate in a training program on the use of non-formal educational places (NFEP). The design of the study is ethnographic and its methodology is qualitative. The study comprehends the analysis of three multiple cases according to the disciplinary area, including teachers of primary education, biology, and physics. The analysis was focused on the discourse of the participants, establishing eight categories which were previously validated through triangulation by time and by instruments. The study concludes that the participants were able to restructure their ideas about the use of NFEP for teaching, showing mainly ontological and epistemological changes, which are discussed in the paper.

Informal learning environments such as exhibitions in museums and science centres have the potential to promote public engagement in the societally important fields of nanoscience and nanotechnology (NST). This study contributes to research-based development of an NST exhibition by mapping educational, communicational and museographical challenges in illustrating nanoscale science. For the methodological framework, the study employs a previously suggested model based on the Model of Educational Reconstruction. Potential visitors’ perspectives were analysed by reviewing research literature on NST learning, and by interviewing science centre visitors. On the basis of the results, the study suggests strategies for illustrating the nanoscale in an exhibition: ways of supporting visitors’ scale conceptualisation, presenting images and visualisations deliberately, and using scale models and macroscopic analogies. The study examines how the educational role of science centres may be enhanced by informing exhibition development with visitor-oriented research.

This study focuses on a youth science camp for pupils in sixth to ninth grades that is organized annually by the University of Jyväskylä, Finland. The main idea of the science camp is to learn to do guided inquiry in nature. The study investigates the significance of science camp for encouraging young participants to learn science and how the camp supports their learning. The research method used was a survey. Altogether, 47 youth participated in the camp in 2012 and 2013. The results show that the participants wanted to learn more about science than secondary school could offer, and science camp had a positive impact on their interest in science. It was possible to introduce important concepts of chemistry and biology in a comprehensible manner through experimentation in an authentic context. The participants worked as researchers in a positive and non-formal learning environment and they received concrete experience with the various phases of scientific research.

Out-of-school environments offer a unique opportunity for experiental learning which transcends the role of educational resources and teachers. This article introduces the special topic of out-of-school learning in science and mathematics education. First, we present the theoretical underpinnings from the movement towards crossing the boundaries of school in educational practices and broadening educational spaces. We continue with the key facets of out-of-school learning through a constructivist approach, aided by the concept of mediation environments as the third educator from a socio-material perspective. Furthermore, we focus our discussion on a selection of articles from this special number as an international overview on out-of-school learning. In the conclusion section, we discuss the gaps that the following works fill, as well as new questions that arise in the area. The closing remarks highlight the promotion of active learning in students, considering the role of the environment as the third educator.

The use of videos as learning objects has increased together with an increased variation in the designs of these educational videos. However, to create effective learning objects it is important to have detailed information about how users perceive and interact with the different parts of the multimedia design. In this paper we study, using eye-tracker technology, how fast and for how long viewers focus on captions and written text in a video. An educational video on thermodynamics was created where captions were used to highlight important concepts. Screen recordings of written text from a tablet were used to illustrate mathematical notations and calculations. The results show that there is a significant delay of about 2 seconds before viewers focus on graphical objects that appear, both for captions and for written text. For captions, the viewers focus on the element for 2-3 seconds, whereas for written text blocks, it is strongly dependent on the amount and quality of the presented information. These temporal aspects of the viewers’ attention will be important for the proper design of educational videos to achieve appropriate synchronization between graphical objects and narration and thereby supporting learning.

Homes have remarkable possibilities to act as science learning environments for young children (3 - 6 years old). This qualitative case study investigated what kind of support parents need to do online science activities with their children at home. Data consisted of parent’s theme interviews (n=7). As a main result, a model of parents’ need for support was produced. The model contains three dimensions: 1) the affective dimension, 2) the knowledge and skills dimension and 3) the organizational dimension. Parents’ own affective experiences, organization of the experiments and finding time to do experiments are important factors to consider, when looking at parents’ willingness to engage in science activities with their children. The parents might not necessarily be content with only the child’s interest in experimenting as a reason to carry out science activities at home, instead they need to be interested and engaged in activities themselves.
