Udacity founder Sebastian Thrun takes stock of what’s working, and what’s not, with regard to online university courses:

As Thrun was being praised by Friedman, and pretty much everyone else, for having attracted a stunning number of students–1.6 million to date–he was obsessing over a data point that was rarely mentioned in the breathless accounts about the power of new forms of free online education: the shockingly low number of students who actually finish the classes, which is fewer than 10%. Not all of those people received a passing grade, either, meaning that for every 100 pupils who enrolled in a free course, something like five actually learned the topic. If this was an education revolution, it was a disturbingly uneven one.

“We were on the front pages of newspapers and magazines, and at the same time, I was realizing, we don’t educate people as others wished, or as I wished. We have a lousy product,” Thrun tells me. “It was a painful moment.” Turns out he doesn’t even like the term MOOC.
