Now, it is one of the largest volunteer organizations at Columbia University, sending volunteers into classrooms in nearby Harlem, East Harlem, and the Bronx. Peace by P.E.A.C.E. teaches methods of conflict resolution in elementary schools using an interactive curriculum. Volunteers teach a semester or year-long curriculum utilizing a visual conflict model. Peace by P.E.A.C.E. teaches students to better communicate with each other, to understand other perspectives, and to mitigate conflict.
