I think this falls in to the same trap as the stories earloer about the LHC Physics group that have abandoned PowerPoint for a whiteboard. That something is a good idea for a particular intellectual exercise its a good idea generally for thinking, learning,success! No, chess is a quite particular skill where you can't afford to make mistakes and the problem is bounded and can be fully rationalised. Most creative or scientific endeavors are quite different and some maybe be best learnt by experimentation trial and error. I'm sure she has a great way to teach chess but I don't think its a panacea.
