Peer tutoring with 12 students in an elementary multi-categorical resource room was initiated as a method of changing interaction from verbal aggression and hostility to overt helpfulness and support for one another. A mini-training session for the six older students instructed them in goals, methods, reinforcement, and modeling. Tutors received rewards of the reinforcement system equal to the student they were tutoring; and after tutoring there was a daily discussion with the tutors about their findings, difficulties, and strategies for a continuing process of remediation and strengthening interpersonal relationships. As the project progressed, the tutors gained in understanding of learning problems and in the process of teaching they firmed-up skills and concepts. (Author/SBH)
