Polling & Peer Instruction - A Brief Online Intro

While I was working in the Provost's Office at Drexel, I developed this chunk of the web as a way of:

1. Explaining an easy-to-try improvement in teaching/learning that relied on technology; and
2. Doing that in the minimum possible space
3. Doing it in a way that a mildly interested or mildly skeptical faculty member might find reasons, and the information needed, to actually try the technique.

What do you think? Seen it done better? More briefly?
