This inquiry examines the personal attribute and environmental factors that contribute to and impede science teacher-leader development. Using a narrative approach, the inquiry focuses on the experiences of three teachers in three different New Zealand primary schools (years 1-6) as they develop in their capabilities as science teacher-leaders…

Describes a study which sought to identify development patterns related to the acquisition of proportional reasoning in two areas, namely electricity and chemical solutions. Results from children ages 9-11 indicated that development of understanding of chemical solutions was asymmetric whereas it was symmetrical with electricity. Includes sample…

Interviews conducted with a group of Lebanese children showed that they give physical rather than animistic interpretations to natural phenomena such as rain, clouds, and falling bodies. (MLH)

Sixty-one Japanese kindergarten children were pretested on their concept of speed; approximately half of the children (experimental group) were then given a demonstration of visual speed, and the entire group was posttested. Concludes that the experimental group could acquire the concept of speed significantly better than the control group. (MLH)

Japanese and Thai kindergarten children were shown the same visual displays of moving objects and asked to compare the speed of those moving objects. The results significantly indicated that Thai children's concept of speed is further advanced than that of Japanese children. (MLH)

Describes the major topics and discussions presented at a bi-national (United States-Japanese) seminar. Concludes that the overriding problem in both countries is the fact that available in-service training is reaching only a very small percentage of the practicing teachers. (MLH)

Results of a previous study indicated no difference in preservice teacher attitude/achievement using lecture/inquiry approaches. This study was replicated, also examining effects of sex and students' (N=471) previous science training. Although results for science understanding were not significant, analysis of attitude change indicates that…

A critical incident approach was used to analyze the discourse which took place during a visit by a class of 8- and 9-year olds to a gallery concerned with food at the Science Museum in London. Data collection, analysis, and interpretation are discussed. Suggests that a critical incident approach may be more generally helpful in analyzing the…

Argues that scientific knowledge in school is a social construct in which curriculum proposals are simply points of departure that are transformed by the social interaction that takes place within the classroom. Considers discourse as playing an important role in knowledge construction. Contains 31 references. (DDR)

Explores ways in which two teachers' views of themselves and their students as knowers of science have an influence on classroom practices. Reports that the teachers seem to view themselves as consumers rather than inquirers in science, and produce a rapport with knowledge similar to that which they themselves experience in their classrooms.…

This study reports the preferences students expressed in regard to problem-solving modes for resolving environmental problems. There were many differences between students at different grades and between girls and boys. Implications for teaching are suggested. (YP)

Conducted an ethnography to evaluate the usefulness of the notion of community of practice in classroom settings. Documents how collectively available knowledge of a classroom community was transformed as resources and practices were adopted by more and more members. Discusses implications for the organization of classroom environments that…

Described are the results of a formal reasoning test taken by both Japanese and American students. The most likely reasons for the difference between test score results are discussed. Japan's "hands-on" and group inquiry-oriented curriculum approach is cited as one difference. (KR)

Survey results contrast teachers' (n=159) knowledge and understanding with the understanding levels expected by England's science National Curriculum. Teacher's understanding with respect to the concepts of force, energy, and changes in materials are discussed. (Contains 29 references.) (MDH)

Reports on the agenda of an exemplary teacher as she planned for and implemented a visit to an interactive science center by her class of 12-year-old boys. Describes activity in three sections: pre-visit preparation, post-visit activities and reflections, and during the visit. Focuses on the nature of student learning and participant teachers'…
