I’ve enrolled to an excellent Coursera course on video games and learning. This subject is so hot for me and I believe new generations will use games as major part of their blended learning experience.
I stole this diagram from the course (Kurt Squire). It shows clearly where social context has a role. Newbies or intermediate players are in my experience not the core of these groups. It starts by master players and it continues to designers or game community leaders.
I just started this course, but in my opinion it has surprisingly high quality. (As by the Coursera Gamification course from Kevin Werbach.)
I consider these forms of education as valid as any classroom education and I really appreciate the effort for putting all this together.
