"Educators knew the online revolution would eventually envelop the physical classroom, but a torrent of near-revolutionary developments in the past month are proving that change is coming quicker than anyone imagined. In just 30 days, the largest school system in the U.S. began offering credit for online courses, a major university began awarding degreeswithout any class time required, and scores of public universities are moving their courses online. The point at which online higher education becomes mainstream is no longer in some fuzzy hypothetical future; the next president’s Secretary of Education will need an entire department dedicated to the massive transition."
