To solve educational problems in schools such as many students who don't attend school regularly or leave school, it is important to create a system in which teachers make collaborative teams so that organizational practice would be realized effectively. The aim of these teams would be to enable students to achieve ideal results and to lead them to a higher level of autonomous activities. The purpose of this study is to explore how to create such a system in terms of theory and practice.

  Questionnaires for teachers and students in Tokyo metropolitan high schools and some administrators ware used and interviews with experienced teachers were conducted in this study. The surveys and interviews were then analysed to identity how to form an ideal student group.
