Games-based learning takes advantage of gaming technologies to create a fun, motivating, and interactive virtual learning environment that promotes situated experiential learning. Many researchers now believe that this approach can better motivate present day entertainment-driven learners to more thoroughly engage in learning through meaningful activities defined in the game context as opposed to those offered using more traditional didactic approaches. This chapter describes games-based learning, the related terms and scope, current approaches, embedded pedagogies and challenges for providing high-quality education in the 21st Century.
