If you haven’t heard of MOOCs, you no doubt will, because these Massive Open Online course are becoming all the rage, tagged as the biggest thing in public education since, well, the dawn of public education. (It wasn’t long ago that the Khan Academy was). My colleague Nick Anderson reported about the emergence of the MOOCs movement as a disruptive force in higher education. But there are reasons to think MOOCs are being hyped, and below, former schools superintendent Larry Cuban explains why. Cuban is a former high school social studies teacher (14 years, including seven at Cardozo and Roosevelt high schools in the District), district superintendent (seven years in Arlington, VA) and professor emeritus of education at Stanford University, where he has taught for more than 20 years. His latest book is “As Good As It Gets: What School Reform Brought to Austin.” This appeared on his blog.
