Gaming and simulation in online courses are important because they make learning more interactive, engaging, and practical. They allow students to experience real-world scenarios in a virtual setting, which can improve skills, enhance problem-solving, and increase motivation. In eLearning environments, these tools help bridge the gap between theory and practice by allowing learners to experiment, make decisions, and see immediate results without real-world consequences. This approach also supports different learning styles and can be adapted for various subjects, from medicine to business, enhancing overall learning outcomes.
