In earlier work, I argued that good commercial video games provide players with “good learning” (see Gee, 2003, 2005, 2007). By “good learning” I mean learning that is guided by and organized by principles empirically confirmed by systematic research on effective and deep learning in the Learning Sciences (Bransford, Brown, & Cocking 2000; Gee 2004; Sawyer 2006). This actually should not to be surprising. Video games are, at their heart, problem-solving spaces that use continual learning, and provide pathways to mastery through entertainment and pleasure.
