Summarizes the evaluation of computer software presented in "The Physics Teacher" since 1984. Describes several programs for integrating courseware use into classes including "TimeLog" for a message/bulletin board, Control Data "Physics 1" for problem solving, some demonstration programs, and "Physics Laboratory Programs" for programing skills.…

Reviews video programs and film materials for the teaching of mechanics. Describes 13 videos of the Open University. Discusses other resources of visual materials. (YP)

Introduces "The Bouncing Ball Project" made for teaching mathematics through practical mechanics. Describes four activities in the project: what is bounciness; drop height and rebound height; timing the bounces; and extension activities. Provides many worksheets, graphs, and a list of five other projects. (YP)

Discusses a visit to a hospital to help students gain an appreciation of technological application. Describes the potential, general and specific considerations, and evaluation of such a field trip. (YP)

Discussed is single crystal X-ray crystal structure analysis. A common link between the NMR imaging and the traditional X-ray crystal structure analysis is reported. Claims that comparisons aid in the understanding of both techniques. (MVL)

Evaluates the overall economic efficiency of a closed resource cycle. Uses elementary thermodynamic definitions of overall thermal efficiency for determining an economically quantifiable basis. Selects aluminum for investigation and includes a value-entropy diagram for a closed aluminum cycle. (MVL)

Describes an advanced NMR project that can be done with a 60-MHz continuous-wave proton spectrometer. Points out the main purposes are to give students experience in second-order NMR analysis, the simplification of spectra by raising the frequency, and the effect of non-hydrogen nuclei on proton resonances. (MVL)

Provides a demonstration for showing the usefulness of thermal principles to physical science students who have difficulty understanding conventional explanations. Outlines materials, procedures, discussion, and advantages of using this method. (RT)

Described are suitable topics to be included in an urban physics trail. Background information, questions to answer en-route, and follow-up questions are included. Required equipment is listed. (Author/CW)

Describes and examines the effects of the eight-week Summer Science Training Program at the University of Iowa. There was no significant differences between students who had completed high school physics and those who had not on the final course examination, course grade, and attitudes toward physics. (Author/YP)

Discusses three broad classes of magnetic behavior: diamagnetic, paramagnetic, and ferromagnetic. Presents a simple lecture demonstration using an overhead projector to synthesize triiron tetraoxide and to show its interaction with a magnetic field and comparing it to a paramagnetic material. (MVL)

Discusses the concept of kinetic versus thermodynamic control of reactions. Explains on the undergraduate level (1) the role of kinetic and thermodynamic control in kinetic equations, (2) the influence of concentration and temperature upon the reaction, and (3) the application of factors one and two to synthetic chemistry. (MVL)

Studies the pressure and energy of particles interacting through a Lennard-Jones potential and correlates thermodynamical properties with system structural characteristics. Analyzes the relationships between computer simulated data and the van der Waals equation. (YP)

Discusses the rationality of students' alternative frameworks by considering the role played by their beliefs, their understanding of other views, and the reasons for justification or rejection. Investigates the way in which 14-year-old boys see the effects of classroom learning experience on their ideas. (Author/YP)

Discussed are medical applications of ultrasound. The physics of the wave nature of ultrasound including its propagation and production, return by the body, spatial and contrast resolution, attenuation, image formation using pulsed echo ultrasound techniques, measurement of velocity and duplex scanning are described.
