Since 1970, 90 adopters in 67 universities have used EXPER SIM for teaching research design and strategy to college students through computer simulation. An analysis of EXPER SIM as an innovation revealed that implementation of the program was not necessarily retarded by its computer dependence. Administrative support seemed to be important in the adoption and implementation of the system. Frequently change or re-invention of the system itself occurred in the process of implementation as users adjusted the system to fit their needs. (CH)
