The document discusses the definition and effective use of simulations for learning. It defines simulation as a realistic, controlled-risk environment where users can practice behaviors and experience the impacts of decisions. The key aspects of simulation are identified as learning, storytelling, and performance. Common myths about simulation are debunked, such as the notions that simulations are just games or require extensive technology. Effective applications of simulation include skill practice in new environments and processes. Constructivism, problem-based learning, and goal-based scenarios are presented as effective learning approaches for simulation.
