Examines the response of physics graduate enrollments to projections of employment for Ph.D. graduates and proposes that equivalent data be collected for other subject fields to facilitate similar studies for all areas. (AL)

A series of short articles providing ideas for the use of electronic apparatus, demonstrations of magnetic fields, demonstrations of the conservation of momentum, and a new idea for an investigation of a black box.'' (AL)

Short articles describe the production, photography, and analysis of diffraction patterns using a small laser, a technique for measuring electrical resistance without a standard resistor, a demonstration of a thermocouple effect in a galvanometer with a built-in light source, and a common error in deriving the expression for centripetal force. (AL)

Describes a nonlecture group technique for teaching physics. Test results are compared with classes using the lecture technique. Concludes that a smorgasbord of methods will probably give the student the best educational opportunity to achieve. (Author/PR)

Describes the development of an autonomous computer-Assisted-Instruction general physics course for liberal-arts students at Florida State University. The course utilizes an IBM 1500 Instructional System to guide the student through a self-paced program of textbook reading assignments and homework problems, audiotaped lectures, PSSC movies, and…

Describes a student laboratory project involving the design of an "acoustic suspension speaker system. The characteristics of the loudspeaker used are measured as an extension of the inertia-balance experiment. The experiment may be extended to a study of Stelmholtz resonators, coupled oscillators, electromagnetic forces, thermodynamics and…

Describes modifications of a commercially available strip-type transmission line, which makes possible reproducible measurements of standing waves on the line. Experimental data yield values for the characteristic impedance, phase velocity and line wavelength of radiation in the transmission line, and the dielectric constant of material in the…

Describes the general features of the feedback classroom, and its uses in the teaching of Physics. Circuit diagrams for the construction of control and response units are presented. The use of these units in evaluating student achievement is described. (LC)
