Bill Gates and others talking about online education

It's a long video about massive open online courses (MOOCs) - over an hour - but I managed to listen while doing something else. Bill Gates comes in after about 40 minutes and is interesting - he's just a little bit sceptical and makes the point that online courses have a long way to go to match the quality of good teachers. But overall it's a balanced discussion and it's worth watching if you're interested in education and impact of new technology.
