ALT has just published a timely and informative "from-the-sharp-end" article by Jeremy Knox, Sian Bayne, Hamish MacLeod, Jen Ross and Christine Sinclair from Edinburgh University's MSC in E-learning Team about their experiences of and reflections on developing the E-learning and Digital Cultures Coursera course. Related to this from the ALT Open Access Repository, you can access a presentation PDF by Andrew Ng and Daphne Koller of Stanford University and Coursera. "The Online Revolution: Education at Scale" was used by Andrew Ng for his 23 July 2012 Invited Talk "Teaching Machine Learning to 100,000 Students" at the 2012 conference of the American Association for the Advancement of Artificial Intelligence. Note that a June 2012 TED talk by Daphne Koller and a July 2012 talk at the University of London cover similar ground.
