Most people learn by direct interaction I'll have to disagree here. I've been a university teacher for over a decade, and the number of students who interact with me is small. Most students don't actually interact with others all that much in learning. Neither did I as an undergraduate or pupil. I'm not saying that's a good thing, but that's a fact. Most learning is auto-didactic in some form or shape. What universities offer is deadlines and penalities for missed deadlines. Those are anti-procrastionation scaffolds that most people (including myself) need for effective long-term learning. MOOCs mostly lack this, and that why MOOCs have not yet replaced conventional schools and universities.
