The Power Teaching seems powerful indeed. But it is too much "in your face" to be broadly applicably. I think it does address some aspect of classroom dynamic and student engagement. Students are required to be attentive to what the teachers are saying and actively respond to (or simply repeat) the fragments of the lessons. One concern is that would students remember anything afterward? Sure they can repeat fragments of the lecture and have memory aids built into the lesson, but understanding the material is a different matter. Sometimes, what students need is quiet time to reflect on the materials. It is a mistake to think that the whole brain learning entails flapping one's arms around and be talking all the time. Pauses are important for students to either ask questions or just quietly reflect. Among other subjects, higher mathematics cannot be taught with gestures and simple repetitions.
