Presents basic physical theory for movement of electric charges in clouds, earth, and air during production of lightning and thunder. Amount of electrical energy produced and heating effects during typical thunderstorms is described. Generalized safety practices are given. (JM)

Findings from a study of California high school physics teachers and students show positive correlations between student perceptions of physics and (1) extent of teacher subject matter preparations, (2) teacher association with other physics teachers, (3) inclusion of historical, social, and political aspects of physics in course objective, and…

Describes a two-year undergraduate multi-disciplinary science course offered at Portland State University. Includes an outline of course content and arrangement. Presents arguments given by members of science departments both for and against the course. (EB)

Describes the characteristics and applications of the seminar/autolecture system, which is an open-ended learning system combining recent advances in educational technology with recent findings in behavioral science. The autolecture involves the use of an overhead projector and a cassette tape recorder. The authors report that the instructional…

Presents the procedures, results, and conclusions of a study designed to collect data on both affective and cognitive variables as well as the behaviors of teachers and students in several physics classes which followed an integrated multi-media, multi-modal teaching-learning system. Comparison was made with a control group of classes.…

Presents a number of applications of computer graphics to problem solving in physics. (LC)

Reports the procedures and results of a student investigation of the performance of a miniature diesel engine. The experiments include (1) torque measurement, (2) power measurement, and (3) variation of power output with applied load. Bibliography. (LC)
