Requiring Professors to teach by certain techniques is certainly going to lead to disaster. While in surgery, newer procedures are almost always a measurable improvement over previous procedures in some way (time, cost, success rate, whatever), I feel it that its simply too difficult to quantify the 'success' of various techniques. Especially when the success depends so much on the course material, professors, and the students. For example, I could hardly imagine Calculus I being improved with video conferencing or blogs.
What benefit would forcing professors to teach integration with powerpoints bring? If anything, I believe there are entire concepts which are better taught on a chalkboard, not with powerpoints or slides. Things where the process matters (like integration, or physics problems) where simply seeing the steps laid out before you seems to miss out on some of the 'magic'. I really feel this because I've just completed a term where I had a calc prof teaching all on chalkboard, and a physics prof who had most of the material laid out in powerpoint, and would fall back to the board when asked a question, or having to elaborate.
There is nothing wrong with encouraging profs to try something new. Provide them with resources and information on new ways to teach. Don't force them. You'll likely just end up with a bunch of profs pissed off at the university admin, and classfuls of bored students.
That said, I do find the use of the clickers really useful. I do wish more courses/profs used them.
