2013 was a year of hype for MOOCs (massively open online courses). Great big numbers and great big hopes were followed by some disappointing first results. But the head of edX, Anant Agarwal, makes the case that MOOCs still matter -- as a way to share high-level learning widely and supplement (but perhaps not replace) traditional classrooms. Agarwal shares his vision of blended learning, where teachers create the ideal learning experience for 21st century students. TEDTalks is a daily video podcast of the best talks and performances from the TED Conference, where the world's leading thinkers and doers give the talk of their lives in 18 minutes (or less). Look for talks on Technology, Entertainment and Design -- plus science, business, global issues, the arts and much more.
