The purpose of this study is to clarify a method to build the human relationship from the result of the study of group cohesiveness and a study of classroom collapse. As a result, I have to consider the study results which made an individual the subject and the study results which made a group the subject. I have to do a theoretical outcome for practice hypothesis clearly from study results of the specialized science. The instruction in consideration of the "Cohesion by the problem" and "Cohesion by the interpersonal" that is results of research of the cohesiveness is necessary for this study. In addition, the instruction in consideration of "Learning instruction", "Student counseling" and "Support of the selfestablishment" that is results of research of the disorder in the classroom is necessary.
