The purpose of this study is to explore the possibility of practicing art classes as an education for peace and unification and to draw implications. For this purpose, peace and unification education, which had stayed in the periphery of the curriculum, was reorganized into project-based art classes targeting middle school students. Students recognized the non-peaceful element through creation, discussion, and presentation, and experienced artistic thinking. As a result of the study, the implications are as follows. First, through the project art class, students faced ‘hate’, ‘conflict’, and ‘prejudice’ within themselves and came to empathize with the feelings and situations of others. Second, Students became critically reflective about social problems and conflict situations. Third, it improved the peace capacity to reconsider and practice the meaning and value of peace. After the transition to peace and unification education, it is meaningful that art classes of peace and unification education were practiced in the absence of teaching and learning materials in the curriculum.
