Simulations support training in various fields by providing realistic and controlled environments for practice and experimentation without real-world risks. They enable learners to apply theoretical knowledge in practical scenarios, enhancing retention and understanding. In sectors like aviation, healthcare, and military training, simulations can replicate complex situations, allowing personnel to develop critical decision-making skills. By immersing users in lifelike experiences, simulations foster engagement and improve performance while also providing valuable data for assessment and adaptation of training programs.
