This paper describes selected nonschool uses of simulation and discusses the implications of each application for education in general. Most of the applications described pertain to instruction and include the provision of an environment for exercising or practicing the application of principles or skills. Applications which are examined include (1) the use by the military of various simulator trainers, auto-instructional simulators, the Pocket Blinker and a War Wound Moulage Kit; (2) the use by the government of simulation planning exercises; and (3) the use by industry of business and management simulation games. An experiment with television-mediated simulation by a Boston UHF channel and the use of simulation in situational response testing by the American Board of Orthopaedic Surgery are also reviewed. Discussion of the implications from these applications for education includes analysis of the factors of cost of the simulation, complexity, realism, uses, and value. Forty-seven references are listed. Appended is a representative listing of "Uses of Instructional Simulation Systems in Industry, Government, the Military, and Other Non-School Uses"; information on each of the 48 items includes the name of the simulation, the designer, the target group, and a brief description.
