A replication study was conducted with five underachieving fourth graders to determine the effects of teacher-written praise notes and associated parent praise as motivating agents for increased performance of assigned school tasks. When Ss completed 80% or more of their work they were given a praise note to take home to parents who were encouraged to provide additional positive reinforcement. Results indicated that all Ss improved their completion of assigned tasks, that their report card grades improved, and that parents were enthusiastic about the program. (DB)
