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.

There are problems in geometry education in lower and upper secondary school, which students have with the spatial imagination and with the understanding of some geometric concepts. In this article, we want to present tasks that show some advantages of the software GeoGebra. We use this software as a tool to visualize and to explain some geometric concepts, as well as to support students’ spatial imagination. Classification: D30, G10. Keywords: space imagination, GeoGebra, mathematics education at lower and upper secondary level.

Science educators have highlighted the need to develop students to integrate knowledge across science disciplines to address real-world issues. However, there has been little research about the development of interdisciplinary assessment instruments. In this research, the instrument that measures the level of upper-secondary school students’ interdisciplinary understanding of environmental issues was developed and validated based upon Wilson’s Construct Modeling framework. After a pilot testing, the revised assessment instrument of interdisciplinary understanding covering five typical environmental problems comprised 14 multiple-choice questions and four constructed-response questions. Five hundred twenty-three eleventh graders, including 279 boys and 244 girls from mainland China, made up the research sample. The partial credit Rasch analysis has verified the reliability and validity of the interdisciplinary understanding instrument. In addition, the results of cluster analysis revealed that over half of the students could use some partially accurate scientific concepts and principles from two or more disciplinary perspectives to deal with a specific environmental issue. The validated instrument can provide insights for assessing and developing upper-secondary school students’ interdisciplinary understanding in science education. Keywords: Environmental Issues, Interdisciplinary Assessment, Interdisciplinary Understanding, Rasch Measurement Model, Science Education

This study aimed to recognize upper-secondary school science teachers’ perceptions of the meaning, importance, and integrating mechanisms of science, technology, engineering, math (STEM) education, taking in to account the differences between the science teachers’ perceptions according to their specialties, years of experience, and degrees. A closed-ended questionnaire was distributed among 700 science teachers (biology, physics, and chemistry) in Riyadh, and 255 teachers responded. The results showed a strong alignment in the upper-secondary school science teachers’ perceptions of the meaning and the importance of STEM education, although there was less of a consensus regarding the integrating mechanisms. There were statistically significant differences in the physics teachers’ perceptions of STEM meaning, although there were otherwise no significant differences by specialty in the science teachers’ perceptions of the importance of STEM education and its integration mechanisms. Furthermore, the teachers showed no statistically significant differences in STEM’s meaning, importance, or integrating mechanisms according to their years of experience. Based on the results, recommendations included intensifying professional development programs on utilizing technology, engineering, and mathematics in learning science concepts and application. Keywords: integration mechanisms, science teachers, STEM education, teachers’ perceptions, upper secondary school

AbstractThis work presents a teaching training workshop on human nutrition topics with strong emphasis on the underlying chemical concepts. It was designed according to the Sustainable Conscious Cognitive Learning Model (SCCLM) and framed in a Context-Based Science Education (CBSE) approach. The proposal was implemented with 44 upper secondary school science teachers. It consisted of three phases. First, teachers were presented with ‘common-sense’ driven sentences on nutrition topics and they were asked if they agreed or disagreed with them. Through an oral discussion, the emergence of the teacher’s own cognitive conflicts was promoted in order to trigger subsequent motivation for achieving further knowledge. Next, main scientific ideas and related chemical concepts were presented for each sentence, along with teaching recommendations to complete a CBSE approach. Finally, teachers were asked their opinions on the didactic proposal. Results showed that teachers were motivated to learn beyond their strong initial non-scientific based ideas by questioning the reliability of the information sources. They were also willing to revisit their teaching on some of the canonical concepts of chemistry.

The article describes a pilot study, an introduction to a series of investigations of upper secondary school pupils’ explanations of sustainable energy. The physics syllabus have the intentions on one hand to guide pupils into science-education and on the other to give insights to pupils in order to participate in the debate on e.g. energy usage. The results obtained, from questionnaire and group discussions, indicate that pupils can get caught in narrow physical explanations of the concept of sustainable energy systems. Some pupils discuss an environmental explanation parallel but show insecurity. One interpretation is that pupils feel an inappropriateness connecting environment and physics. An implication is that the concept of energy quality might be an accessible way for pupils to relate concepts of physics with environmental questions.
