A MOOC is a “Massive Open Online Course.” These are offered by edX, a leader in online education. The idea is that while a traditional classroom gets limited in how many students can attend, with a MOOC, as it gets offered through the internet, literally millions of folks can all take the class and benefit from the education. It is literally an economy of scale so that high quality education can be disseminated.
