E-learning, flipping the classroom, blended learning... it's been exploding recently.
Here are links to three podcast with some central actors in the field:

A presentation by Salman Khan at the London School of Economics

A presentation by Sebastian Thrun from Udacity for the Commonwealth club of California on april 17. 2013

And finally, some interesting critical observations from Nicholas Negroponte, ex-head of MIT Medialab, speaking for the Long Now Foundation. He argues that videoinstructions and online tests are disastrous for learning. He calls it instructionalism.

His remarks are concentrated 44 minutes into the programme.
