Henry Jenkins brings together some threads underlying the concept of serious games. The principles include things like: games occur with specific learning contexts; the games supplement, but do not replace, teachers; games should inspire exploration and experimentation; games promote social and not individual learning; every element of the game is meaningful. I think these principles are problematic, a set of principles that will please existing educators and educational institutions, but which do not point the way forward. If I had to put the distinction in capsule form, I would say that this describes "games in learning" but what we really want to be exploring is "learning in games". Just like, say, the distinction between "communities in learning" and "learning in communities".
