On this holiday week, we're rebroadcasting our most popular episode of 2017:

Barbara Oakley, a professor of engineering at Oakland University, spends a lot of time these days thinking about how people learn. She’s taught more students than just about anyone else on the planet, as one of the instructors of one of the most popular online courses ever, which has had two million registered students over the several times it’s been offered. The title of the course, is Learning How to Learn.

EdSurge recently talked with Oakley about what she’s learned teaching all those online students. And she makes the case for why free online courses like hers—which are known as Massive Open Online Courses, or MOOCs—might still lead to a revolution in higher education, even though the hype around them has died down.
