You may have heard the famous quote from Confucius, which says, “I hear, and I forget. I see, and I remember. I do, and I understand." This concept perfectly sums up why training simulations are effective. Unlike a lecture or a video, simulations let learners practice or “do” the tasks they need to master. Training simulations come in various formats. If the process allows, you could have the learner use the actual equipment to perform a fictional procedure.
