The document discusses the use of computer simulations and gaming to enhance learning. It defines computer simulations as representing real-world processes through computer programs. Simulations allow people to experience things virtually without being physically present. Interactive games both entertain and teach lessons or subjects through goals, feedback, challenges, and story elements. They can assess learning and develop skills. Examples of educational simulations and games are provided, with the conclusion that they can engage students by allowing them to explore concepts they cannot in real life at progressively increasing levels of difficulty.
