This paper describes an evaluation the 1988-89 implementation of the Resolving Conflict Creatively Program (RCCP), which began in Community School District 15 in Brooklyn (New York) as a collaborative effort with the city's board of education and other community school districts and agencies. The evaluation assessed RCCP components and the RCCP's impact on participating students, staff, administrators, and school climate. The RCCP focuses on conflict resolution and intergroup relations, shows young people non-violent alternatives for dealing with conflict, teaches children skills to make non-violent alternatives to conflict real in their own lives, increases students' understanding and appreciation of their own and different cultures, and shows children that they can play a powerful role in creating a more peaceful world. The RCCP includes a 20-hour training course for teachers, regular classroom instruction in creative conflict resolution based on a 10-unit curriculum, classroom visits by expert staff development consultants, and a student mediation component. The evaluation used data from a teacher survey, an administrator survey, a student achievement test for a representative sample of participating fourth through sixth graders, and peer mediation instruments. Results show that the RCCP provides exemplary services to participants in District 15 and has had a positive initial implementation in Districts 2, 27, and 75. Participants' had extremely positive assessments of all RCCP components. The RCCP had a positive impact on students, staff, and classroom and school climate. Children's attitudes and behaviors changed in positive ways as a result of their RCCP participation. The mediation component was successfully implemented and fostered more peaceful class and school environments. Included are three tables. (RLC)
