Hans Taparia gives the following recommendation for the EdX course of this post’s title in his New York Times op-ed “The Future of College Is Online, and It’s Cheaper”:

Most biology professors, for instance, would find themselves hard pressed to match the pedagogical quality, production values and inspirational nature of Eric Lander’s online Introduction to Biology course at M.I.T. That free course currently has over 134,000 students enrolled this semester.

Hans also mentions Georgia Tech’s inexpensive online MBA:

Georgia Tech, a top engineering school, launched an online masters in computer science in 2014. The degree costs just $7,000 (one-sixth the cost of its in-person program), and the school now has nearly 10,000 students enrolled, making it the largest computer science program in the country. Notably, the online degree has not cannibalized its on-campus revenue stream. Instead, it has opened up a prestigious degree program to a different population, mostly midcareer applicants looking for a meaningful skills upgrade.
