Murals have become a powerful art form for portraying antiwar, human rights, social justice, and human dignity issues. Educators and artists have conducted mural workshops with adolescents in international settings to educate them about peace, human rights, and cultural tolerance. Learning with murals has been shown to be pedagogically meaningful in helping students better understand their ethnic, historical, and cultural roots and communities; collectively find resolutions to a community's problems; and advance cooperative learning skills. Murals have been found to be effective in enhancing learning in a variety of content areas. This article describes a weeklong workshop in which Korean and American students worked together to create a peace mural, and provides insights for teachers conducting similar work with an intercultural group of students. The workshop was intended to promote a culture of peace and intercultural competence among participants and help them develop cooperative learning skills, goals that are deeply intertwined.
