The evaluated project is an approach to the individualization of instruction in reading and mathematics in the junior high school. Among the instructional approaches used were diagnostic/prescriptive teaching, games and simulations, as well as traditional teaching procedures. Project goals included raising student achievement, improving attitudes, and demonstrating the novel use of gaming-simulation. Both product and process evaluations were conducted. The product evaluation included a measure of student achievement and attitude. The process evaluation involved an implementation evaluation study, staff evaluation components, and an intensive involvement study. The authors conclude that the program was successful in achieving all of its objectives in mathematics and most of the reading objectives in terms of student achievement. (MK)
