Ten thousand students have just taken the final exam in MITx's course "6.002x Circuits and Electronics." The sheer size of this course (120,000 first registered back in March), the high-wattage backing of MIT for a certificate of completion to all those who make it through to the end, and the free, open access nature of this MOOC (a "massive open online course") seemingly ushers in a fundamentally new paradigm in higher education. When coupled with the recent headlines about similar ventures such as Coursera, Udacity, and MIT's own new partnership with Harvard to form edX, the policy world has been positively aglow: David Brooks calls it a "campus tsunami"; John Chubb proclaims it an "historic transformation"; Thomas Friedman writes, simply, "welcome to the college education revolution."
