Could an online degree earned in six to 12 months bring a revolution to higher education?

This week, AT&T and Udacity, the online education company founded by the Stanford professor and former Google engineering whiz Sebastian Thrun, announced something meant to be very small: the “NanoDegree.”

At first blush, it doesn’t appear like much. For $200 a month, it is intended to teach anyone with a mastery of high school math the kind of basic programming skills needed to qualify for an entry-level position at AT&T as a data analyst, iOS applications designer or the like.

Yet this most basic of efforts may offer more than simply adding an online twist to vocational training. It may finally offer a reasonable shot at harnessing the web to provide effective schooling to the many young Americans for whom college has become a distant, unaffordable dream.

Intriguingly, it suggests that the best route to democratizing higher education may require taking it out of college.
