Abstract
The purpose of this research is to clarify the effect of students' collaborative activity and mutual evaluation in a comprehensive seminar of a university teacher training course. In the preliminary research, collaborative activity and mutual evaluation were accepted by the students. The main research investigated how students' thoughts changed during the collaborative activity and mutual evaluation, and whether there was validity in students' mutual evaluation. Because dissatisfaction was caused by the arrangement of group members, each member's contribution in a group was evaluated by the other group members. As a result, it could be clarified that the students had accepted the method of evaluating contributions in a group. In this research, the groups were composed of three or four students. Each group discussed a problem in education, and designed a teaching idea to solve the problem. The teaching idea of each group was presented with a poster and a projector, and students evaluated other groups. Students were interested in this approach, considered the teaching ideas well and came to understand them deeply. However, when the number of students greatly exceeds 50, this method of teaching will not be feasible.
