MOOCs, (pronounced mooo-ks), Massive Open Online Courses are free courses taught online by a number of universities: Harvard, MIT, Stanford, University of Michigan, University of Pennsylvania, and many others. The courses range in subject from chemistry, physics, programming, computer science, business, history, political science, philosophy, Nordic film studies, and too many subjects to fully mention here.
