An individualized motivation system was used to increase the performance of three students using a computerized number facts program. Previous research on number facts suggested that performance increments might occur through massive practice and/or changes in processing ability. In this study, points exchangeable for extra gym time were contingent upon daily individual accuracy increases of 5% or a rise to 95% accuracy or higher. A multiple baseline design was used and each student showed increases in accuracy rate and items attempted. In addition, improvement was also seen on an independently administered paper and pencil test. It is suggested that similar procedures be considered for other students requiring remedial academic work. (Author/CH)
