Academia is buzzing about MOOCs. What sounds like genteel name-calling is actually a powerful new medium with potential to transform the education system. Indeed, MOOCs and mooks are simply unfortunate homophones but the former is certainly ruffling feathers because their aim is to make higher education more affordable (free, in fact). These Massive Open Online Courses picked up speed and weight like a freight train, with more than five million learners in locations spanning the whole globe. Academic heavyweights like Harvard, Stanford and MIT back the courses, giving the world of online learning a much-needed boost of credibility.
