In this paper, we review research on how students' interest in science changes through the primary to secondary school transition. In the literature, the findings generally show that primary students enjoy science but come to lose interest during secondary school. As this claim is based mainly on interview and questionnaire data, that is on secondary reports from students about their interest in science, these results are reexamined through our own extensive material from primary and secondary school on how interest is constituted through classroom discourse. Our results suggest the possibility that primary students do not lose their interest in science, but rather that an interest in science is never constituted. The overview indicates that studies relying on interviews and questionnaires make it difficult to ascertain what the actual object of interest is when students act in the science classroom.

Although misconceptions in science have been established in interview studies, their role during the learning process is poorly examined. In this paper, we use results from a classroom study to analyze to what extent nonscientific ideas in electrochemistry that students report in interviews enter into their learning in a more authentic setting. We audio-recorded talk between eight pairs of Swedish upper secondary students during a practical on electrochemical cells. Learning was operationalized on a discursive level as a description of what students do and say when taking part in an activity. This enabled an analysis of how encounters with misconceptions influenced the development of students' reasoning, compared to other encounters during the learning experience. Misconceptions did not constrain the development of students' reasoning. Rather, their reasoning developed in response to the contingencies of the specific situation. When misconceptions were encountered, they appeared as alternatives and questions not actively defended. Sometimes, encounters with these misconceptions were generative of the students' reasoning. The results indicate that demonstrating misconceptions in interviews is not enough to assume that they interfere with learning in other contexts.
