Interviews of and questionnaires given to (n=299) 14- and 15-year-old students in England and Spain on their understanding of combustion and on the teaching and learning styles used with students found that the extensive use of practical work in English schools had only a marginal effect on their understanding of combustion. Includes…

Presents an alternative to the use of a radar to determine how fast an individual can serve a tennis ball. Equipped with a tape recorder and a Macintosh computer, students determine the velocity of a tennis ball by analyzing the sounds and echoes heard on the court. (ZWH)

Eighteen year-11 physics students were taught heat and expansion of liquids using a predict-observe-explain sequence. Argues that the data demonstrate how students' prior knowledge and beliefs can affect their observations and interpretations of new learning. (Author/MKR)

Examines the problem of determining the minimum center of mass for a can with a varying height of liquid in it. Uses PC SOLVE computer software to graphically represent the problem situation. (MDH)

Described is a curriculum development project aimed at stimulating girls' interest in physics with a view to encouraging more girls to pursue the subject further. Included are the background information, implementation, and implications for science teaching. (KR)

The significant stages in the development of understanding of the concept of electric charge are discussed. The history is outlined with references to certain important experiments, and suggestions are made for relevant school demonstrations and experiments. (KR)

Discussed is the idea that energy is the cause of change. This idea, going back to early cognitive development, means that the teaching of energy needs to confront how, thermodynamically, people can perform actions. The change in energy caused by differences is emphasized. (KR)

Discusses four topics presented in the science foundation course of the Open University that exemplify current developments in particle physics, in particular, and that describe important issues about the nature of science, in general. Topics include the omega minus particle, the diversity of quarks, the heavy lepton, and the discovery of the W…

Presents experiments to measure the velocity of sound through metals and other amorphous materials. Describes the equipment used to make the measurements and the possibility of interfacing with a microcomputer. (MDH)

Fourteen elementary and middle school teachers from an inservice physics course were found to share a common core of strongly held propositions that formed a coherent, but incorrect and contradictory, model of the sequential flow of electrical current. Theoretical and practical implications of these teachers' beliefs with respect to both…

Studies of the relationship between students' propositional knowledge (as measured by concept mapping tasks) and their study strategies (as measured by self-report questionnaires) for electricity in first-year university courses are described. The effect of propositional knowledge and prior knowledge on both conceptual knowledge and study…

A workshop that provides instruction about chemistry and physics concepts and about novel hands-on ways to teach the concepts using toys is described. Sample topics by discipline and related toys and a daily workshop schedule are included. The results of formative, summative, and follow-up evaluations are presented. (KR)

Effects of animated graphics presentations on incidental learning and the degree to which various computer practice activities contain intrinsically motivating characteristics were studied with 70 fourth graders learning about Newton's laws of motion. Incidental learning occurred without sacrifice of intentional learning. Students were highly…

Results of an experiment offering single-sex and mixed-sex physics classes in a private secondary school indicated that girls in single-sex classes participated more frequently; students overall experienced greater learner satisfaction; and single-sex classes had a statistically significant, positive influence on girls' interest in physics-related…

Synthesizes existing, isolated bits of information on U.S. secondary student enrollment in advanced science courses. Among the findings for grades 10, 11, and 12, the percentage of those students enrolled in Advanced Biology is 20, 26, and 54. Advanced Chemistry is 0, 33, and 67; and Advanced Physics is 0, 10, and 90. (PR)
