Last year my district paid teachers to take a graduate class worth 2 credits
(double bonus!) called Peer Coaching, we learned how to observe and record
data in different ways, and we also learned how to discuss what we saw in
non-threatining ways. It can be done many different ways, and was very
helpful, but also time consuming - we had to use our planning period to do
the observations and then find another time to meet. I'd be glad to talk
more about it if you're interested.
