Describes a teacher-researcher's investigation into barriers to student adoption of an alternative referent for learning and its consequential learning strategies in an 11th-grade chemistry class. Suggests that various contextual factors influenced students' willingness to adopt the alternative referent, and that students' beliefs, trust of the…

Presents an action-research study of student scientific literacy that is analyzed by two metaphors of learning: students working in science as if they follow recipes, and students working in science as if they devise recipes. Considers the usefulness of the metaphors as a framework to provide common ground for otherwise divergent views on…

Describes action research on the efficacy of problem-based learning using a hermeneutic dialectic methodology. Focuses on the emergence of students' critical-thinking skills, the relevance of science concepts taught, the interdisciplinary nature of the problems addressed, and the changing roles of the teacher and students. Reports that the course…

Describes the turbulent conditions that typify experiences as a science supervisor in the central office of a large urban school district implementing science systemic reform. Notes that typical policies and procedures allow stakeholders to undervalue the decisions they make, which creates currents of frustration and distrust capable of…

Describes the development of the educational system in Mozambique since the country's independence in 1975. Addresses administrative and supervisory structure, primary education, pre-university school and adult education, teacher education, and current reform programs. (WRM)

Criticizes the national curriculum in England and Wales for not giving elementary-school teachers the freedom to explore relationships between subjects, especially as they relate to scientific and technological literacy. Argues that teacher education in science and technology and teacher input into curriculum development must also be improved.…

Gives a rationale for, and benefits of, having preservice science teachers conduct a science exhibition for high school students and teachers. Provides organizational hints and recommendations. (WRM)

Describes students' (n=175) understandings of the structure of animal (including human) skeletons and the internal organs found in them. Finds that older students have a better knowledge of animals' internal anatomies, although knowledge of human internal structure is significantly better than knowledge of rat, bird, and fish internal structure.…

Finds that the time required to attempt all the test items of each question paper in a four-paper sample was inversely proportional to the percentage of students who attempted all the test items of that paper. Extrapolates results to give guidelines for determining the feasibility of newly-developed exam papers. (WRM)

Describes the nature of environmental education research in the 1990s, and comments critically on the focus and quality of inquiry in this field with a view toward improvements in the new millennium. Organizes the literature around the themes of quantitative reports, qualitative research, descriptive reports, focused inquiries, metamethodological…

The priorities for science must change to confront the social and environmental problems brought on by the policies in science and technology during the past century. Contends that educators must have a clearer, broader understanding of the nature of science, its history, and its current structure in order to effect necessary changes in science…

Critically examines the literature to establish what evidence exists to support family-school links for student outcomes in science. Provides an analysis of existing programs developed to support student learning in science. (Contains 55 references.) (WRM)

Summarizes arguments for and against teaching ethics within science education, and clarifies what might be the several aims of teaching ethics in science. Discusses how ethics instruction might be incorporated into the science curriculum. (Contains 120 references.) (WRM)

Presents an empirical study of listerv usage in an undergraduate computer science course to understand how email lists contribute to the learning experience and to improve the value of listservs in courses. Provides evidence that the listerv was an important information source and was an effective tool for peer-to-peer learning. (Contains 7…

The international literature suggests students frequently resort to the use of formulae when solving stoichiometry problems without understanding the concepts. In prior work we identified Thai student alternative conceptions and ability to solve numerical problem for stoichiometry. The results indicate that many Thai students also hold alternative…
