Teacher professional development (PD) is seen as a promising intervention to improve teacher knowledge, instructional practice, and ultimately student learning. While research finds instances of significant program effects on teacher knowledge, little is known about how long these effects last. If teachers forget what is learned, the contribution…

While there has been an increased focus on inquiry-based learning in teacher preparation programs, little is known about the influences of these programs on teacher development over time. Using activity theory as its theoretical framework, the researcher employed a longitudinal interpretative case study design to examine the development of three…

This qualitative study explores a cohort professional development experience that brought new teachers together every few weeks from across an urban school district. Observation data were analyzed through Wenger's (1998) "Communities of Practice" social learning framework. The purpose was to examine how a cohort can be a valuable resource of new…

Effects of a computerized professional development (PD) program for a concept teaching routine were investigated in two studies. For each, teachers were randomly assigned to either a virtual workshop group that used a multimedia software program for PD or an actual workshop group that participated in a live PD session. In Study 1, the teachers'…

This study assesses the impact of professional development schools (PDSs) on preservice teachers, comparing PDS and non-PDS candidates at the point of licensure. Data sources include student teaching evaluations and portfolio presentations. Statistical analyses reveal PDS candidates scored significantly higher than non-PDS candidates on aspects of…

Discusses the challenges in assessing Professional Development School (PDS) impacts, noting examples of assessments from the literature. The paper outlines a conceptual framework for assessment and explains how it may help organize more systematic thinking about PDS evaluation. Examples from a multisite case study demonstrate how one consortium of…

To date, the professional development school (PDS) preservice teacher preparation literature base is long on attitudinal analysis and short on comparative analysis of outcome variables. This article reports on a 2-year study comparing the lesson planning, teaching effectiveness, postlesson reflectivity, and content retention of professional…

The purpose of this study was to understand how teachers and graduate-level scientists negotiated differing knowledge bases to work together to improve science teaching and learning. Partners' coparticipation in and dialogue about pedagogical decisions and actions were analyzed. Three theoretical representations of dialogic interactions emerged…
