Research on nature of science (NOS) and scientific inquiry (SI) has indicated that a teacher's knowledge of each, however well developed, is not sufficient to ensure that these conceptions necessarily manifest themselves in classroom practice (Lederman & Druger, 1985; Lederman, 2007). In light of considerable research that has examined…

Investigated the nature of biology teachers' global content understandings, and sources and formation of subject matter structures (SMSs). Reports that the initial formation of SMSs was credited to college content courses and modified by the act of teaching. Variables that differentially affected SMS translation included teacher intentions,…

The development and role of subject matter knowledge within teachers' professional development is currently the source of much research; however, the parallel development and role of pedagogical knowledge has yet to be systematically analyzed. In investigating this seldomly tapped area of concern, researchers involved 26 preservice science…

Ten preservice biology teachers were followed through the final year of their preservice education to assess the content and stability of their knowledge structures of biology. A questionnaire asking the subjects to list the topics which make up biology and to diagram these topics in relation to one another was completed three times during the…

Reports on a study to test the validity of the assumption that a teacher's conception of the nature of science directly influences his/her classroom behavior. Recommends a redirection in science education to promote more adequate conceptions of the nature of science in secondary schools. (TW)

Reviews research from the past 40 years on students' and teachers' conceptions of the nature of science, clarifies the basic assumptions and logic which have guided earlier research efforts, contrasts the results from qualitative and quantitative research, makes recommendations about research methods, and suggests avenues for future research about…

Current reform efforts in the teaching of high school biology demonstrate the need for a synthetic treatment of prominent concepts. There exists insufficient research that delineates the global content understandings--in this paper designated subject matter structures (SMS)--of biology teachers; or that assesses whether these SMS do, in fact,…

This longitudinal investigation assessed the development and changes in preservice science teachers' conceptions of subject matter and pedagogy as they proceeded through their secondary science methods course, practicum, microteaching, and student teaching. Twelve preservice science teachers were asked, on four occasions each several weeks apart,…
