Examines instructional plans of four beginning teachers preparing to teach familiar and unfamiliar topics in biology. This analysis constitutes one level of a multimethodological study of effects of teacher subject-matter knowledge on high school science teaching. Among conclusions are that teacher's choice of instructional strategies affects…

Concept mapping was used to tap the conceptual disciplinary (science subject) knowledge and pedagogical knowledge of seven biology and six geography teachers with short or long teaching experience. Results indicate that knowledge in both areas is unsatisfactory, experience does not improve the knowledge, and teachers mastered disciplinary…

This study documented the teaching practices of 2 exemplary biology teachers of grades 11 and 12 by means of an interpretive research methodology. Teaching practices are identified that may be considered exemplary and worthy of attention and analysis by other science teachers and science teacher educators. (PR)

This study quantified possible changes in the classroom learning experiences of high- and low-ability pupils, which might accompany an organizational change from streamed to mixed-ability classes for science learning in secondary schools. Deteriorations in the quality of the classroom interactions of both high- and low-ability pupils were found.…
