This paper presents the results of a study designed to facilitate teacher candidates' shift from students of mathematics to teachers of mathematics. We develop a series of tasks each of which encourages candidates to reconsider rich tasks from increasingly teacher-centric points of view. The results show that using authentic high school student…

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…

Primary teacher training programmes in New Zealand do not provide training about specific communication disorders (SCDs), despite prevalence of SCDs of approximately 7%. This pilot study investigated the effectiveness of a three-hour professional development (PD) programme for a specialised group of primary teachers, Special Education Needs…

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…

Within the past few years, there have been numerous studies that suggest that preservice teachers need and want opportunities to observe, visit, interact, and collaboratively reflect with teachers who are attempting to implement reform-based teaching strategies. Unfortunately, for many schools of education, it is logistically difficult to locate a…

This paper discusses the findings of a case study conducted with an English as a Foreign Language (EFL) teacher at a German secondary school. This case study is part of a research project that investigates the new competencies that EFL teachers need to acquire in order to be able to use the interactive whiteboard (IWB) to develop their practice,…
