Group evaluation: a collaborative, peer-mediated behavior management system.

The efficacy of a consensus based group-evaluation system was examined using a reversal design. Two groups of students with disabilities served as subjects. The group-evaluation system involved: (a) dividing the groups into teams; (b) having each team agree on a common rating for the group's behavior during a specified time period; (c) comparing each team's rating to the teacher's rating; and (d) delivering reinforcement to each team based on the group's behavior and the team's accuracy in rating the group's behavior. Results indicated that the group-evaluation system was an effective strategy for modifying classroom behavior.
