Reports in detail on the results of a study indicating that physics students' prior understandings of key concepts are systematically related to the way they approach their studies, their perceptions of learning context, and the quality of the outcomes of their studies. Includes references. (CMK)

Presented are problems that teachers can use to stimulate students' thinking about the subject of mathematical scaling. Food and eating examples are used to illustrate this concept. (CW)

The teaching of physics as an integral part of an undergraduate oceanography course is described. A general outline of oceanography and the corresponding physics topics is given. The objectives, organization, and difficulties of such a course are discussed. (CW)

Presented is a demonstration of magnetostatic image poles in the presence of ferromagnetic materials. The experimental set up and probable results are discussed. Real and image systems are illustrated. (CW)

An ethnographic account of the community of academic physicists is based on interviews, and a picture of what physics is like as a discipline is constructed. The features of its epistemology that differentiate it from other disciplines and characteristics (career structure, value-system and preferred modes of communication) are described.…

Considers pressure, volume, entropy, temperature, Helmholtz free energy, Gibbs free energy, enthalpy, and internal energy. Suggests the mnemonic diagram is for use with simple systems that are defined as macroscopically homogeneous, isotropic, uncharged, and chemically inert. (MVL)

Results of a British study indicate that, among potential applicants (N=177), a small demand exists for a proposed science education degree program. Findings suggest that recruitment of science and math teachers may be hampered because the satisfactions provided by teaching are unlike those sought by science and math specialists. (IAH)

Describes the discovery and characteristics of superconductors. Discusses some experiments on the levitation of a magnet over a superconductor. (YP)

Describes experimental procedures to produce magnetic fields with a thermocouple. Provides diagrams showing the apparatus, tables of experiment data, and background information on the theory. (YP)

Describes the change of earth's magnetic field at the boundary between the outer core and the mantle. Measurement techniques used during the last 300 years are considered. Discusses the theories and research for explaining the field change. (YP)

Provides instructional models for solids, liquids, and gases that incorporate a few adjustments for keeping the features and scale as valid as possible. States that 99 percent of the material in the universe is in a dominant form called plasma. (RT)

Explains changes in the scientific world view. Describes the classical mechanistic-reductionist paradigm and some modern examples of changes including evolution, self-organizing universe, non-linearity, subjectivity, and software. (YP)

Presents background information related to astronomy for high school students. Discusses the differences between astronomy and astrophysics, and the employment of the astronomy graduates. Lists degree programs in astronomy and related subjects in an appendix. (YP)

Discussed are several topics on medical imaging including x-rays and Computer Assisted Tomography (CAT) scans, magnetic resonance imaging, fiber optics endoscopy, nuclear medicine and bone scans, positron-emission tomography, and ultrasound. The concepts of radiation dosage, electrocardiograms, and laser therapy are included. (YP)

Examined are tenth-grade Western Australian students' conceptual knowledge of gravity and the motion of the planets. Students were interviewed with seven cards, and a four-item diagnostic test based on the interview data on the first four cards was developed. A total of 113 students' responses to the test are summarized. (YP)
