Computer-based simulation (CBS) represents a unique utilization of computers for instruction that combines some of the best features of the technologies of simulation and computer assisted instruction (CAI). CBS grew out of an interest in testing the application of CAI to procedural and perceptual motor skills. With the sophisticated graphics capabilities curently available in many CBS systems, it is possible to program dynamic, two-dimensional representations of physical objects to be displayed on the screen of a computer terminal. Research suggests that advantages of CBS for training include increased trainee proficiency, time savings, cost effectiveness, and student acceptance. The overall recommendation for research in this area is to approach CBS training with a futuristic orientation to ensure maximal utilization of newly emerging technologies. (Author/CMV)
