The vast majority of people who sign up for a MOOC - a massive open online course - never complete it. More than 50% consume less than half of the course’s content.

The assumption behind that conclusion is that you have to complete a whole, semester-long course to get value from online education. As a MOOC addict, I can tell you: that’s not true. Instead, I’ve found there are at least three good ways to learn from MOOCs, depending on your goals and the time you plan to spend.
