Udacity Reevaluates Online Education

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.
