This article uses data from 65 teachers participating in a K-2 mathematics professional development research project as an example of how to analyze video recordings of teachers' classroom lessons using mixed methods. Through their discussion, the authors demonstrate how using a mixed methods approach to classroom video analysis allows researchers…

This paper provides an account of professional learning in action through documenting the experiences of three upper primary teachers as they engaged in reflection-on-action with the assistance of an academic mentor. Video-stimulated recall was used as a mechanism to encourage productive reflective practice, using video footage of each teacher's…

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…

This article reports on an investigation of how teachers of geometry perceived an episode of instruction presented to them as a case of engaging students in proving. Confirming what was hypothesized, participants found it remarkable that a teacher would allow a student to make an assumption while proving. But they perceived this episode in various…

The present article addresses how lesson study can facilitate changing traditional norms of individualism, conservatism and presentism that constrain American teachers from learning from one another. The article investigates how lesson study can serve as a vehicle for developing teacher learning communities by developing or redeveloping teachers'…

This study examines changes in teachers' thinking as they participated in a video club designed to help them learn to notice and interpret students' mathematical thinking. First, we investigate changes in teachers' talk about classroom video segments before and after participation in the video club. Second, we identify three paths along which…

This article describes the theoretical framework, research base, structure, and content of a video-based professional development program implemented during 2 consecutive years with sixth-grade mathematics teachers from five low-performing schools. First, difficulties teachers encountered in responding to video-based prompts during the 1st year…

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…

This study demonstrates the possibilities of videopaper to support teacher professional development in a workplace setting. A team of five mathematics teachers in a secondary school was followed over a period of six months as they worked jointly to improve their teaching and team practice. In a stepwise strategy for deliberate and object-oriented…

The purpose of this study was to explore the potential value of online video case discussions among preservice and inservice teachers, and the video case teacher as a tool for the professional development of teachers. Participants included a total of 26 preservice and inservice mathematics teachers and a veteran teacher who appeared on the video…
