Watching the Thomas Saurez TED talk about his experience learning and building apps for iPad and iPhone, I was struck with the thought that the desire to change teaching into this type of learning is valid but often blocked by cost benefit analysis.  If what I do is working for many students, will the cost in time and resources of implementing creative "out of the box" student experiences pay off.  I hope that I can push myself through that wall and have faith in the inventiveness of students and know that they will make the learning happen if given open options.  For this reason I am very much looking forward to Applied Physics as it will be very new, very open and potentially hard to harness.  But harnessing learning is maybe not the reason to teach...
