An operant-based corrective reading program was established to study effectiveness of peer tutoring in the school, for reading deficient children. Sixty-nine second to fourth grade students were matched on measures of initial reading ability and level of reading retardation, and randomly assigned to three groups: Peer Tutoring Only, Peer Tutoring with Home Based Reinforcement, and Control. SRA materials were used in training for the experimental groups, supplemented with additional reading materials. The program continued for 15 weeks, in seven public schools. Changes in oral reading accuracy and comprehension were assessed. Both reading and comprehension were significantly increased by peer tutoring, relative to the control group. The addition of home-based reinforcement doubled this increase. The measured gain in oral reading, based upon standardized testing, was 0.19 years for the controls and 1.27 years for peer tutoring with home-based reinforcement. Internal measures of gain showed similar results, and comprehension gains were also comparable. A high rate of compliance with the tutoring program was maintained by the tutors. High ratings of satisfaction were obtained for the program, from all groups of participants. The feasibility of the program for application in the school system is discussed.DESCRIPTORS: reading, tutoring, comprehension, peers, elementary school students Several investigators have demonstrated that contingency management procedures can effectively modify academic performance (Coleman, 1970;Harris, Finfrock, Giles, Hart, & Tsose, 1975;Kazdin & Bootzin, 1972;O'Leary & Drabman, 1971;. These procedures are often costly in terms of teacher time. Measurement and observation of performance, and the management of teacher attention or other contingencies may be impractical in many classroom settings.The behavior of children in school can also be influenced by reinforcement administered at Robertson, DeReus, and Drabman (1976).The separate studies of home-based reinforcement and peer tutoring indicate that potential benefits may accrue from the union of these two methods. The two procedures were studied in combination by Wilson (Note 2), who found that when peer tutoring was combined with a home-based reinforcement procedure, gains in reading accuracy were greater than the gains achieved by peer tutoring alone. In addition, gains achieved in the combined condition were consistent across all subjects whereas gains for peer tutoring alone were found for some subjects but not for others. However, Wilson's study reports data for only five subjects, and no clear effects of contingencies were shown for reading comprehension.In research on reading the importance of reading comprehension is often overlooked. Staats and Butterfield (1965) The present study examined reading accuracy and reading comprehension for groups of children given peer tutoring, with or without an added home-based reinforcement system. Gains were assessed using measures both internal and external to the training program. In additio...
