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…

Professional development programs today increasingly ask teachers to capture video in their own classrooms to share with peers. Yet little work has explored the nature of the videos that teachers produce for this purpose. This study takes a first step by looking inside a set of almost 200 videos collected by 84 K-2 teachers participating in one of…

Take a deeper dive into understanding the five practices-anticipating, monitoring, selecting, sequencing, and connecting-for facilitating productive mathematical conversations in your middle school classrooms and learn to apply them with confidence. This follow-up to the modern classic, "The 5 Practices in Practice: Successfully Orchestrating…

Videos are often used for demonstration and evaluation, but a more productive approach would be using video to support teachers' ability to notice and interpret classroom interactions. That requires thinking carefully about the physical aspects of shooting video--where the camera is placed and how easily student interactions can be heard--as well…

Numerous video-based programs have been developed to support mathematics teachers in reflecting on and examining classrooms interactions without the immediate demands of instruction. An important premise of such work is that teacher learning occurs at the time that the video is viewed and discussed with teachers. Recent advances in technology,…

There is a general consensus among researchers and teacher educators that classroom video can be a valuable tool for pre-service teacher education. Media such as video are not, however, in themselves effective. They have to be embedded in an instructional program to be useful. Yet, little empirical research examines how specific instructional…

Professional vision helps the teacher decide where to focus attention and what interactions are most critical at the moment. Despite the importance of teachers' professional vision, the authors find that teachers do not always have opportunities to reflect on and further develop their professional vision. During instruction, a student's comment or…

Focusing on expanding technical capabilities and new collaborative possibilities, we address 4 challenges for scientists who collect and use video records to conduct research in and on complex learning environments: (a) Selection: How can researchers be systematic in deciding which elements of a complex environment or extensive video corpus to…

This paper examines a group of secondary mathematics teachers who met 16 times to discuss video excerpts of their teaching. The explicit purpose of the meetings was to assist the teachers in preparing video for submission to the National Board for Professional Teaching Standards. Analysis of meeting transcripts reveals that teachers engaged in…

This article examines a model of professional development called "video clubs" in which teachers watch and discuss excerpts of videos from their classrooms. We investigate how participation in a video club influences teachers' thinking and practice by exploring three related contexts: (a) teachers' comments during video-club meetings, (b)…

This study explores the use of video clips from teachers' own classrooms as a resource for investigating student mathematical thinking. Three dimensions for characterizing video clips of student mathematical thinking are introduced: the extent to which a clip provides "windows" into student thinking, the "depth" of thinking…

Recent years have seen an increase in the use of video for teacher education and professional development accompanied by widespread recognition that to be beneficial, video must be used in activities that induce particular modes of inquiry. However, little is known about how teachers typically watch video. The present study investigates the use of…

The study of teachers' professional vision poses some unique challenges. The application of professional vision happens in a manner that is fleeting, and that is distributed through the moments of instruction. Because of the ongoing nature of instruction, it is not realistic to expect that one could "pause" instruction momentarily, ask a…

This study investigates mathematics teacher learning in a video-based professional development environment called "video clubs." In particular, the authors explore whether teachers develop professional vision, the ability to notice and interpret significant features of classroom interactions, as they participate in a video club. Analysis for the…

Video is currently a key element of numerous professional development programs, yet relatively little is known about how video fosters changes in teachers' thinking. This study examines how a particular type of video-based professional development, namely video clubs, supports teacher development. Video clubs are professional development…
