Classroom Discussion Techniques that Work?

Recently I [Peter Pappas] blogged about the teacher-centric information flow in the traditional classroom. See: Engage Student Discussion: Use the Social Network in Your Classroom If you would like to see my point illustrated, you can do a quick "Hollywood classroom walkthrough" with this clip from "Stand and Deliver." Before you play the video, create a diagram with eight small circles labeled teacher and student responders 1-7. As you watch the video, keep track of the sender/ receiver in each exchange of information with lines and arrows. Once you have finished with the diagram, reflect on a few broader questions:

1. Were the students comfortable offering their answers?
2. What feedback did the teacher give after each student answer?
3. Did the students get any closer to a valid answer as each, in turn, ventured a response?
