MOOCs are big current news. But what do teachers think of it? This conversation began with teacher Alex Tabarrok concluding that online education works, expressing delight at the way it was able to leverage his 15 minute talk on TED, which was watched 700,000 times, which he works out to be equivalent to 175,000 student-hours of teaching offline. Kevin Carey (The Radical Implications of Online Education), Siva Vaidyanathan (The New Era of Unfounded Hyperbole) & Alan Ryan (Some skepticism about online education) weighed in with their views. Ends with Alex’s response to the participants. A quiet revolution is on-going in education, so this is a very pertinent read.
