I have used video in a variety of ways, but the first time I used video in my classroom, I was told by my assistant principal that we would each be videotaping ourselves as we teach a lesson, and then watching it with her to debrief the lesson. I was amazed at what I was made aware of from the opportunity to take the role of "student" in my classroom. Together with the AP we set goals for my next steps. Since I was part of seeing the video, I was part of the process of goal setting and was therefore able to really buy-in to the next steps. Now as an instructional coach, watching clips of a teacher's practice with the teacher can have the effect of moving a full jump ahead of where we might have gotten simply through debriefs. We also upload videos to the Teaching Channel and share practice across schools, so that teachers, especially those who don't have a collaborator, can start to collaborate with one another.
