Science teachers' beliefs about teaching and learning are a vital component of teachers' professional competence and are often assumed to impact classroom practice. To date, these beliefs have been predominantly investigated regarding teaching and learning in general or for a particular science subject (e.g., physics). It remains to be determined…

The purpose of this qualitative case study was to explore what aspects of two first-year elementary teachers' practices were most consistent with an inquiry-based approach, what PCK served as a mechanism for facilitating these practices, and what experiences have mediated the nature and development of these teachers' PCK. For each of the…

Alternative certification programs (ACPs) have been proposed as a viable way to address teacher shortages, yet we know little about how teacher knowledge develops within such programs. The purpose of this study was to investigate prior knowledge for teaching among students entering an ACP, comparing individuals with teaching experience to those…

Discusses the concept of pedagogical content knowledge within the context of science teaching. Defines the concept and identifies teaching experience as the major source of pedagogical content knowledge. Contains 69 references. (DDR)

Identifies the major tenets of a preservice secondary education program, knowledge structures that beginning science teachers have constructed about the teaching and learning of science, and the correlation between them. Findings indicate that aspects of the program such as student-centered learning, cooperative learning, general pedagogical…

Examines changes in the science content representations of two prospective elementary teachers during their first year in an experimental teacher preparation program. Finds that opportunities to engage in cycles of instruction guided by structured considerations for content representation contributed to improvements in the teachers' science…

Pedagogical content knowledge (PCK) is a much debated and studied construct. In this article, we adopt an all-embracing view of PCK to examine the development of one elementary science teacher's knowledge over a 10-year period. We portray this teacher's knowledge at three critical points in her career--as a student teacher, beginning teacher, and…
