Advances in technology have made it increasingly easy for teachers to film and share video recordings from their own classrooms, and much research exists highlights the rich learning that can occur when teachers watch and discuss video. Here, Miriam Gamoran Sherin, Jennifer Richards, and Mari Altshuler examine the opportunities for learning that teachers experience when recording and viewing video of their own classrooms. They specifically describe how recording can support teachers in learning to notice, focusing their attention on aspects of classroom interactions that are most important for student learning.
