MOOC: ¿tsunami, revolución o moda pasajera?

There are millions of people in the world who have followed some kind of MOOC (Massive Open Online Course) to date. There are hundreds of thousands who are currently enrolled in some of these courses. We can be more or less critics with MOOC, however by the effects that were producing before, it would not be total nonsense the tsunami term, that Brooks (2012) used in a New York Times article (3-5-2012) to qualify these massive, open and online courses.
