It has been common to use video records of instruction in teacher professional development, but participants have rarely been encouraged to evaluate teachers and students' actions in those records, allegedly because evaluation deters from the development of a professional discourse. In this study, we inspected teachers' online discussions of…

This study explored how peer and professor facilitations are related to teachers' behaviors during video-case discussions. Fourteen inservice teachers produced 1,787 turns of conversation during 12 video-case discussions that were video-recorded, transcribed, coded, and analyzed with statistical discourse analysis. Professor facilitations (sharing…

This study employed a randomized experiment to examine differences in teacher and student learning from professional development (PD) in two modalities: online and face-to-face. The study explores whether there are differences in teacher knowledge and beliefs, teacher classroom practice, and student learning outcomes related to PD modality.…

This study used text-related, video-based case materials to assess teacher candidates' readiness to communicate with families. Participants (N = 141) rated their efficacy for home-school communication and then responded to a description of a classroom-based challenge regarding one student's behavioral and academic performance. Next, they evaluated…

Many educational researchers across the United States have found that inquiry-based learning (IBL) supports the development of deep, meaningful content knowledge. However, integrating IBL into classroom practice has been challenging, in part because of contrasting conceptualizations and practices across educational fields. In this article, we (a)…

This study explores the relationship between teacher knowledge and student learning in the area of mathematics by developing and evaluating an innovative approach to assessing teacher knowledge. This approach is based on teachers' analyses of classroom video clips. Teachers watched 13 video clips of classroom instruction and then provided written…

While video has long been used to capture micro teaching episodes, illustrate classroom cases and practices, and to review teaching practices, recent developments in video annotation tools may help to extend and augment teacher self-reflection. Such tools make possible the documentation and support self-analysis using verifiable evidence as well…

Filling the knowledge gap in the limited research on professional development leaders is an urgent issue if teacher learning is to be improved. This research and development project is studying how leaders learn to cultivate mathematically rich professional development environments. The authors adapted two frameworks from classroom-based…

Leading a classroom discussion involves multiple components, including establishing norms for participation, assisting students in engaging in careful readings of text ahead of time, and modeling features of academic discourse. In other work, Grossman and her colleagues refer to this as the "decomposition" of practice--breaking down complex…

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…

The author defines protocol materials, discusses their development, then examines how the initiation of U.S. Office of Education (USOE) support modified the original definition. (The USOE Master Coordinate System is included as an appendix.) (JA)
