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…

Inquiry is essentially a process in which research questions are asked and an attempt is made to find the answers. However, the formulation of operational research questions of the sort used in authentic scientific inquiry is not a trivial task. Here, we set out to explore the possible influence of separating the research question from the…

This study further extends a conceptual framework that explores science teaching as a "practice" not reducible to the application of formal knowledge, but as informed by teachers' practical-moral knowledge. A hermeneutic model was developed to examine practical-moral knowledge "indirectly" by investigating teachers'…

Presents a case study of problems that can occur when teaching the topic of redox reactions to grade-11 students. Concludes that the teachers' scientific expertise is an important source of difficulties when teaching redox reactions. Discusses implications for improvement of current chemistry classroom practice and content-related teacher…

Reports a study of the quality and extent of understanding of certain well-known theoretical concepts which are held by prospective teachers (N=173) of chemistry in Yemen. Results indicate that teacher understanding ranges from a partial understanding with a specific misconception to no understanding. Contains 25 references. (DDR)

Reports on the views and attitudes of secondary science teachers (n=27) toward lesson planning. Describes teacher decisions, the things they take into account, what they ascribe the most importance to, time spent, the source of their knowledge, and how they evaluate the results. Contains 46 references. (Author/WRM)

Explores the science content knowledge of elementary school teachers and its possible role in helping them teach effectively. Studies the issues in the context of an investigation of the views of elementary school teachers (n=106) who had participated in professional development courses that focused on the topic "natural and processed…

Addresses the teacher's role in the integration of science and technology studies within an educational reform in Israeli junior high schools. Concludes that a realistic goal would be to enable science and technology teachers to cooperate with one another. Contains 35 references. (DDR)

Describes how two teachers collaborated with a university-based researcher/teacher educator to design and implement more authentic science in a grade 7 classroom. Discusses the ways in which the teachers changed their views about science and science teaching, the anxieties they experienced, and the institutional constraints that impacted their…

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…
