As the challenges that schools face are complicated, collaboration has been focused as the one of the professionalities of the teaching profession.

Collaboration of teachers has features peculiar to it. On the other hand, the collaboration has the basic features that collaborations of the other professionals also have, for example, equal relationships and a listening attitude. In the teacher training institution, it is important for students to learn the basic features of collaboration.

  One practical means is educational activities for children by students’ organizations. For the activities, students plan and manage the plays for children. For example, in “Friendship” Education Programs, it is said that students learn how to collaborate with other students through planning and managing.

  However, in educational activities by students’ organizations, students don’t always collaborate with other students. One student sometimes may decide something by using his position. The other student sometimes may proceed the meeting without listening to other students. Therefore, if students’ organizations are to be positioned as a place to learn the basic features of collaboration, it is necessary to facilitate students’ collaborative relationship in the organizations.

  The purpose of this paper is to consider the way to facilitate collaborative relationship in the educational activities by students’ organizations. For this purpose, I researched “Atsumare-wanpaku-tai” consisting of students of Chubu University department of contemporary education. The frameworks of the analysis are the “theory of action” and the theory of “organizational learning” developed by Chris Argyris and Donald A. Schön.

  As a result of the analysis, it is clear that “Atsumare-wanpaku-tai” has a communication pattern that obstructs students’ collaborative relationship. Unconsciously, students often followed the pattern. By the discovery of this pattern, students found the necessity of change and began to change the pattern consciously. Therefore, it is suggested that analyzing the communication pattern of students’ organizations could be a trigger promoting their collaborative relationship.
