異なるグループ学習プロセスがグループ対話に及ぼす影響の事例的検討：６年算数「比とその利用」における解法探索型と解法発表型のグループ学習の比較

抄録

In sixth grade arithmetic class, in order to clarify the characteristics of group learning of the solution search-type group, in which group members find the solution while discussing, and the characteristics of group learning of the presentation-type group, in which each other’s solution is presented and examined after self-resolution, an interpretive analysis of an utterance case of one session of group learning was carried out. Compared to the presentation-type group, there were more “opinions” in the solution search-type group, in which group members added their opinions while finding solutions. As to differences in interaction, in solution search-type group learning, interaction by a chain of extended utterances was found in the activity of describing and verbalizing the solution, whereas in the presentation-type group learning, interaction by changing questions and explanations was observed among group members with different solution methods.
