Power Teaching

I watched this video on "Power Teaching" http://www.utsa.edu/tlc/Video.html and I'm not sure what to think about it. My first impression was "this is cool!" but after thinking about it, I'm not sure. Students are certainly awake, engaged and seem happy, but I'm wondering if this method gets just as monotonous as a straight lecture. There's not a lot of reflection and although students are "active" I'm not sure this method allows studets to "interact" with the content. Somehow I have the impression of trained monkeys. What do other people think? Has anyone tried it?
