- This paper describes analysis of teaching instances that are part of an in-service preschool teachers programme about chemistry and physics in preschool. The aim is to develop knowledge about the communication established between teacher and children in relation to an object of learning, specifically the role of intersubjective communication in relation to an object of learning. A set of science activities with a specified object of learning was developed in groups of teachers and researchers. A qualitative analysis of the communication in relation to the chosen object of learning was performed. The focus of the analysis was excerpts representing differences in intersubjectivity related to the object of learning and what can be said to characterise the communication between teachers and children in these situations. The results show that intersubjectivity can occur in different ways with different consequences for children’s opportunities to experience the intended object of learning. In connection to this, the importance of teachers having a mutual simultaneity in the communication with children about a specific content is highlighted. The teachers have to create links between the child’s perspective and the object of learning. Intermediary objects of learning are discussed as supporting elements in the conquest of new knowledge.

Tidskriftsartikel (refereegranskat)abstract
- This article discusses the role of mathematics during physics lessons in upper-secondary school. Mathematics is an inherent part of theoretical models in physics and makes powerful predictions of natural phenomena possible. Ability to use both theoretical models and mathematics is central in physics. This paper takes as a starting point that the relations made during physics lessons between the three entities Reality, Theoretical models and Mathematics are of the outmost importance. A framework has been developed to sustain analyses of the communication during physics lessons. The study described in this article has explored the role of mathematics for physics teaching and learning in upper-secondary school during different kinds of physics lessons (lectures, problem solving and labwork). Observations are from three physics classes (in total 7 lessons) led by one teacher. The developed analytical framework is described together with results from the analysis of the 7 lessons. The results show that there are some relations made by students and teacher between theoretical models and reality, but the bulk of the discussion in the classroom is concerning the relation between theoretical models and mathematics. The results reported on here indicate that this also holds true for all the investigated organisational forms lectures, problem solving in groups and labwork.

Context-rich vs. context-stripped approach to NOS teaching : teachers’ reflections
- 2015
-
Konferensbidrag (refereegranskat)abstract
- The inclusion of nature of science (NOS) in science education, has for a long time been regarded a crucial component in the teaching for scientific literacy. Much has been written about teachers’ views of NOS and how NOS is taught in the science classroom, but less is known about the teachers’ views of the teaching of NOS. To be able to better understand how NOS becomes (or does not become) a part of science education, teachers’ views of the teaching of NOS needs to be investigated. Therefore, in this project, we aim to shed light on teachers’ ways of coping with two different approaches to NOS teaching – contextualized and decontextualized. We explore how the teaching of NOS is planned for, and communicated in the science classroom, as well as what difficulties and gains the teachers experience with the different approaches. The participants are Swedish in-service science teachers (n=6) in grades 3-9. During the project the teachers meet in focus groups, guided by a researcher, and discuss NOS and the teaching of NOS. Sources of data are audio recorded focus-group discussions and classroom observations. The results indicate that both approaches have benefits. A larger amount and more complex NOS aspects are addressed in the context-rich approach. However, the teachers in this study find the decontextualized task easier to fit within the traditional science-teaching frame.
