Abstract

<p>The purpose of this study is to investigate how the group discussion by students in their experiment activities of upper secondary school influences their scientific thinking. In view of the changes in their descriptions before and after their group discussion and their self-evaluation of the discussion and the transcript, it was possible to observe the following: (1) The number of students who could explain their conclusions on the basis of results increased after the group discussion, and their descriptions became more logical. (2) Almost all the students, including not only those students who were taught but also those who taught, felt that their own thoughts were deepened through the group discussion. (3) It was possible to grasp how the group discussion was conducted in the experiment activities by means of recording the discussion for the purpose of self-evaluation. (4) Categorical analysis of the transcripts revealed the basis of the self-evaluation and its reliability. (5) Selecting appropriate teaching materials for experiments fostered active group discussions.</p>
