Learning environment research should take into account postpositivist ways of thinking to assist students and teachers to construct a more emancipatory learning environment. A critical perspective could lead to research playing a larger role in the transformation of science classroom learning environments. Presented a case study of a middle school…

The Third International Mathematics and Science Study (TIMSS) endeavored to achieve a balance between student learning of school science in a competitive sense and the variety of science learnings that contemporary curricula for science expect. The impact of science-technology-society (STS) on science curricula is used to explore these tensions in…

Analyzed metaphors used by science teachers in their classroom discourse and their influence on the image of science constructed by students. The use of role-determining objectivist metaphors signifies teachers' pedagogies being governed by an objectivist epistemology. Teachers need to reflect critically on their use of metaphors to develop a…

Investigated students' understanding of the concept of weightlessness and found it to be influenced by the confusion between the concepts of weight and gravitational force. The causal structure of students' knowledge presents a platform for interpreting students' alternative ideas about weight and related physical concepts, which could guide…

Used a constructivist teaching/learning approach to improve first year preservice primary teachers' confidence in, and attitude to, teaching science. Benefits reported were ownership of knowledge, development of pedagogic skills, and the use of group work to develop ideas. Concerns raised included uncertainty when exploring knowledge for…

Described a probe that can assess the learners' understanding of scientific ideas in conditions that do not demand closure on a single interpretation, and where learners can demonstrate certainty or otherwise in several possible alternatives. Can be used in monitoring conceptual change when intuitive understanding of scientific phenomena is to be…

Presented a categorization of types of science education research, their possible contributions to cognitive science, and the potential of results from cognitive science for enriching the science education research accounts. Explored the relationship of an example of cognitive work to cognitive science. (15 references) (Author/JRH)

Interviewed Chinese migrant students concerning recognition and comprehension of science concept labels in Chinese and English. Found mean recognition and comprehension scores to be higher in Chinese, with indications that science knowledge learned in Chinese deteriorated with increasing time of residence in Australia. Discussed implications for…

Describes the use of the Questionnaire on Teacher Interaction (QTI) in senior biology classes (n=489) and students' perceptions of their interpersonal relationships with their teachers in the classroom environment and its association with student outcomes. Reports that student attitude scores were higher in classrooms in which students perceived…

Presents a fictional account of a science teacher and her use of constructivism as a referent for her various roles. Describes how she came to teach in this manner, her involvement in staff development activities, and an evolution in her thinking from an objectivist to a constructivist system of semantics. Presents implications for the reform of…

Argues that the alliance between the government and the scientific establishment has resulted in reforms that do not help future citizens in understanding the complexities of the social relations of science and technology. Presents evidence of a return to a conception of scientific literacy in which the central mythology of value-free science is…

Conducted a study (n=26) to test descriptions about learning associated with open-ended design projects and to clarify the notion of ownership of resources and practices. Reports that conceptual and material resources were shared among students and that tool-related practices were appropriated as newcomers participated with more competent others…

Conducted a study to show in an audiovisual form how technological activities can be planned and implemented successfully at the primary school level. Demonstrates how science and technology can be linked in the curriculum. Reports that designing a unit that takes advantage of the symbiotic relationship between science and technology can lead to…

Investigated children's conceptualization of scientific phenomena and intuitive methods learned from their everyday experiences. Explores the nature of tinkering within the context of electricity. Presents a model of tinkering that provides a conceptual framework for the interpretation of tinkering as one of the methods students use to make sense…

Examines 4 biology and 10 chemistry textbooks to determine the types of analogies, their ranges of presentation style, and their efficacy to effect students' conceptual understandings. Presents recommendations to teachers for improving the teaching and learning of biology and chemistry by investigating instructional strategies and clarifying their…
