A model of the phenomenon of the desert mirage is presented using Snell's Law and simple programing techniques. Optical trajectories predicted by the model are illustrated. (CW)

Described is a project involving the introduction of microcomputers into the laboratory portion of a college general physics course for data collection and analysis. The results of an evaluation of this program are presented. (CW)

Described is a symposium of Nobel laureates held in the summer of 1990 to discuss cosmology. Different views on the structure and evolution of the universe are presented. Evidence for different theories of cosmology is discussed. (CW)

Investigated was the effect of concept mapping on science achievement. It was concluded that mapping concepts prior to, during, and subsequent to instruction led to greater achievement. (CW)

The practice of dividing up a group of students on the basis of previous educational experience or achievement, and subjecting the different groups to different educational experiences is defended. Two case-studies of streaming in the departments of accountancy and physics at a university in New Zealand are presented. (Author/MLW)

Presents a review of research focusing on scattering, elution techniques, electrozone sensing, filtration, centrifugation, comparison of techniques, data analysis, and particle size standards. The review covers the period 1986-1988. (MVL)

Presents an easily performed experiment to determine sucrose concentrations using a laser and a hollow glass prism. The experiment is suggested for high school, freshman college, and instrumental analysis classes. Notes an Erlenmeyer flask can be used instead of a prism. (MVL)

Described is a Dutch thematics physics curriculum recently developed for the average academic secondary student. Discussed are the structure, contents of units, and systematic units of the curriculum. (CW)

Describes a secondary school visitation program by scientists in Australia. The program was designed to increase students' motivation related to science, especially physics. Discusses the effects of the program. (YP)

Identifies and discusses the overlap between mathematics and physics at different educational levels. Presents some examples of the overlap and some suggestions for teachers. (YP)

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)
