We posit that professional development (PD) models fall on a continuum from highly adaptive to highly specified, and that these constructs provide a productive way to characterize and distinguish among models. The study reported here examines the impact of an adaptive mathematics PD model on teachers' knowledge and instructional practices as well…

In the United States, about one third of new teachers being hired are drawn from alternative certification programs. One way to address controversy about the differences among the training experiences of teachers in traditional certification programs, fast-track alternative programs, and residency alternative programs is to examine teacher reports…

The effectiveness of teacher education was examined by taking two indicators into account: future teachers' mean achievement on a paper-and-pencil test as an indicator of quality, and the variability of teacher achievement due to background characteristics as an indicator of equity. In detail, the effects of gender and language on mathematics…

The Teacher Education and Development Study in Mathematics, sponsored by the International Association for the Evaluation of Educational Achievement, is the first data-based study about mathematics teacher education with large-scale samples; this article is based on its data but develops a stand-alone conceptual framework to investigate the…

This article uses Andrew Abbott's concept of jurisdictional challenge to analyze the current challenges facing university-based teacher educators. The author suggests that teacher educators are dangerously close to losing jurisdiction over two key professional tasks--the preparation of new professionals and the production of academic knowledge for…

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…

This study assessed the effectiveness of the Alliance Summer Geography Institute's model in promoting teachers' content knowledge and pedagogical content knowledge. Teacher surveys and evaluations of subsequent inservices indicated the institute enhanced both types of knowledge. Resulting inservices allowed teachers to pass knowledge along to a…
