A summer institute was designed to provide 22 certified elementary and secondary social science teachers the opportunity to focus upon concepts and development principles in the methods of learning games and instructional simulation. The 4-week schedule of learning and workshop activities provided a mix of concepts and practice, development and evaluation in these areas: (1) introduction to behavior-based learning systems, systems analysis of simulations and games; (2) positioning simulations and games in a curriculum, the social psychology of simulations and games, modeling learning games; (3) simulation models, analysis, and participation; (4) learning through simulation, educational research on simulation, and developing simulation materials. Major strengths of the program were in its design: (1) the learning environment based on learning objectives, contract programs, competency requirements, and materials; (2) accommodation of diverse interests allowing for individual objectives and implementation; (3) center facilities ideal for materials development, testing, and evaluation, and the well-trained, experienced center staff. Major weaknesses resulted from time limitations.
