"The interest in game-based learning has accelerated considerably in recent years, driven by clear successes in military and industrial training as well as by emerging research into the cognitive benefits of game play. Developers and researchers are working in every area of game-based learning, including games that are goal-oriented; social game environments; non-digital games that are easy to construct and play; games developed expressly for education; and commercial games that lend themselves to refining team and group skills. At the low end of game technology, there are literally thousands of ways games can be - and are already being - applied in learning contexts. More complex approaches like role-playing, collaborative problem solving, and other forms of simulated experiences have broad applicability across a wide range of disciplines, and are beginning to be explored in more classrooms." - 2010 Horizon Report: K12 Edition
