Game-based learning involves students learning through playing games. It allows trial and error, role-playing, and treating topics as systems rather than just content. There are different types of games including short-form used in a single class and long-form extending over weeks. Various genres exist like drill and practice, puzzle, role-playing and simulations. Games have been shown to increase learning, engagement for both students and teachers, and motivation compared to traditional lectures. They create learner-centered classrooms and allow learning through participation and collaboration.
