The world over, secondary school science is viewed mainly as a practical subject. This may be one reason why effectiveness of teaching approaches in science education has often been judged on the kinds of practical activity with which teachers and students engage. In addition to practical work, language--often written (as in science texts) or oral…

Of concern is an international trend of students' increasing reluctance to choose science courses in both their final years of secondary school and tertiary levels of education. Research into the phenomenon indicates an influencing factor to be the "uninteresting curriculum" (OECD "2006") of school science. This paper presents…

Science educators often suggest that students should learn science in ways and settings that bear family resemblance with "the real thing." Internship in science laboratories constitutes one such way in which students may learn science and learn about science. However, very little is known about "how" participants experience a…

Explores a case study of a class of 10th grade students whose learning of genetics involved activities using BioLogica, a computer program that features multiple external representations (MERs). Findings indicate that the MERs in BioLogica contributed to students' development of genetics reasoning by engendering their motivation and interest but…

Investigates the use of the World Wide Web (WWW) as a research and teaching tool in promoting self-directed learning groups of 15-year-old students. Discusses the perceptions of students of the effectiveness of the WWW in assisting them with the construction of knowledge on photosynthesis and respiration. (Contains 33 references.) (Author/YDS)

Investigates factors affecting students' ability to consistently apply the concept of adaptations. Individual interviews were conducted with 74 Year 10 students in Australia, of whom only 47% showed an understanding of the concept. It was found that the students were more likely to apply the concept to vertebrates. (AIM)

Reports on a longitudinal study based on Years 7-12 for girls' achievement in mathematics and science. The data suggest that Year Nine is crucial for girls' perceptions of how they have performed in math and science in relation to boys' achievements in these fields. (AIM)

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…

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)

Investigates high school students' perceptions and attitudes toward mathematics and science and their perceived reasons for not performing well in mathematics and science. Reports that boys have more favorable attitudes and that gender differences in attitudes increased as students progressed through high school, irrespective of school type and…

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…

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…
