A home-based reinforcement program was instituted with three underachieving fourth graders who exhibited inappropriate behavior. Each day the children brought home a workbook assignment indicating percentage of correct responses and parents provided reinforcement for correct items and for improvement over time. Effectiveness on completion of daily assignments and performance of inappropriate behavior was examined via visual inspection and interrupted time-series analysis. Parents received initial training in implementing the reinforcement program along with a book outlining similar procedures. In addition, weekly followup contacts were made. All students improved on both behavioral and academic performance. Academic performance covaried with the levels of corresponding inappropriate behavior of target students. The simplicity of the intervention was stressed. (CL)
