I recently participated in an Instructional Coaching workshop hosted by CREC. Part of the learning was developing reflective practices to improve instruction and ultimately student learning. One method to accomplish this was using video to help teachers focus on goals for instruction and student learning. There was one excellent training video that could be used by teachers to reflect on their own practices, by coaches to foster conversations with colleagues, or by mentors who are training new teachers. It is titled Using Video to Improve Practice: Do It Yourself! and features Sarah Brown Wessling.
