These last few days I've been immersed in a professional experience that has shifted my direction as a teacher: how to use video as a means for facilitating my own and my colleagues' professional growth.
To use video observation successfully, one key is to look objectively at a video of classroom practice and identify critical teacher actions and student actions that are observable–and to note or record these observable actions without evaluation or judgment. Instead of watching teachers and thinking "I like how they did that" or "that is not a good assignment," my attention shifted to noticing the actions without judgment: "The teacher waited while the student revised his own incorrect verbal answer" or "The student recorded her thoughts on a continuum to self-assess."
Judgment is not forbidden, it just isn't first. By identifying the "observables"–the objective concrete details of teaching and learning–I can build a better foundation for evaluating what I can use to improve my own practice and what specific actions can do this. This all got me thinking.
