In classrooms, the students spend lots of time by interacting each other. This paper debates the role of importance of the schools for rising students' social relations. Interaction between students is inevitable. That is because, they are together in projects, class discussion and peer working groups. Multicultural diverse school climates demand more flexible, meaningful, productive humanly relations. These relations circulate in every age and environment as Bronfenbrener (1979) hierarchy model. Researches for this issue manifest scientific application to this notion (Goleman, 1995; Ellias et al., 1997) from the perspective of social emotional learning. Successful researches have been conducting from all over the world mainly in U.S. and European countries and Australia. Educational psychology researchers have very important mission in this curricula issue.
