Examines student discourse in both small and large contexts. Explores the role of shared inquiry and the nature of consensus-building in students' development of explanations from a collaborative knowledge-building stance. Concludes that two forms of discourse (constructive and generative, dialectic and persuasive) effectively promote progressive…

Describes the development and validation of the Cultural Learning Environment Questionnaire (CLEQ) which assesses eight scales of the culturally sensitive environments of secondary school students. Examines associations between students' perceptions of their culturally sensitive learning environment, their attitudes towards science, and…

Explores the involvement and professional growth of a teacher in a professional development project entitled Simply Science. Findings indicate an increase in the teacher's pedagogical content knowledge and confidence in teaching science and a change in her views about cooperative learning strategies. Discusses implications for the design of…

Uses a qualitative approach to uncover a teacher's thinking process during planning and to depict a more holistic view of the structural complexity of teacher cognition during lesson planning. Findings indicate differences between specialized science teachers and general teachers in the levels of structural complexity in their thinking process.…

Investigates students' (N=736) conceptions of inertia and compares these conceptions with historical changes in the concept. Findings indicate considerable similarities as well as dissimilarities between students' conceptions and the views of past scientists. Contains 31 references. (Author/JRH)

Reports on a pilot study which sought to find out what 4- to 8-year-old rural Australian Aboriginal children think about night and day. Findings indicate more variations in thinking than were found in earlier research. Raises questions about the framing of cross-cultural research and the realization of indigenous data. Contains 40 references.…

Explores student performance in chemistry examinations on items that require higher-order cognitive skills (HOCS) or lower-order cognitive skills (LOCS). Findings indicate that students performed considerably lower on questions requiring HOCS than on those requiring LOCS. Performance on questions requiring HOCS may not correlate with that on…

Investigates students' (N=277) performance and the effects of pre-training on tasks rated high in ambiguity, in particular those where the solution to the tasks cannot be arrived at through predictable algorithms. Findings show pre-training to be a significant factor in improving students' ability to plan and carry out open-ended investigations.…

Investigates student teachers' understanding of science and their ability to learn what was needed when it was required for teaching purposes. Findings indicate that half the students were able to prepare themselves adequately through independent research with guidance although their initial background knowledge of science was weak. Discusses…

Examines both theoretical and practical perspectives on conceptual exchange--exchanging a student's entrenched view on a scientific topic for one based on actual scientific perspective. Endorses the conceptual-mediation model based on interference theory for changing an established view. (AIM)

Describes various tools, materials, and experiences used to facilitate critical reflection in teaching prospective science teachers. Tools discussed include portfolios, journals, learning maps, the use of metaphors, and proverbs. Such tool use may provide support to generate science-education reform. (AIM)

Reports on a study done at Oxford University on why young people chose to pursue a career in the physical sciences and engineering. Characteristics of schools that appeared to influence students to pursue a study of science were also investigated. Currently, England, Australia, Canada, China, Japan, and Portugal have contributed information to…

Based on key word counts from summaries in the ERIC database and article analysis of the 1975, 1985, and 1995 volumes of Research in Science Education, certain trends appear in the style of research in science education. Trends include the move from brief, controlled, laboratory-style experiments to lengthy observations and descriptions of…

Discusses the effect of collaboration via e-mail links on the quality of 10- to 11-year-old students' science investigative skills in six elementary rural schools. The project identified several important issues related to teacher-inservice training requirements, development in cooperative groupwork for children, and software design. (AIM)

Discusses an alternate path to teaching introductory stoichiometry based on research findings. The recommendation is to use problems that can be solved easily by rapid mental calculation as well as by pure logic. (AIM)
