The Purpose of this study is to investigate and suggest a personality education approach for solving interpersonal problems of elementary school students that elementary school teachers are now confronted with. In this study, first of all, the actual conditions of interpersonal problems of elementary school students were examined focusing on interpersonal aggressions(violence and victim). The features and problems of existing approaches for solving interpersonal problems of elementary school students were indicated. Although existing approaches for solving interpersonal aggression problems took temporary and external changes, they failed to notice psychological hurts that victims and aggressive victims got. As a fundamental and systematic way for overcoming problems of existing approaches, forgiveness education based on empirical-scientific forgiveness researches was discussed. The Purpose of forgiveness education is to make victims(aggressive victims) overcome the negative responses derived from interpersonal conflict(hurts and victims) and to facilitate them to response positively through experiencing forgiveness psychological process.
