Describes a series of experiments which use a modified automobile alternator as a portable source of three-phase alternating current. The low frequency capabilities of this source allow the phase relationships to be demonstrated using an ordinary galvanometer. (GS)

Discusses teaching the concept of temperature at several levels of difficulty; includes ideal gas thermometers and the kinetic theory of gases. (MLH)

Presents syllabuses for various British curriculum projects in physics and chemistry that include thermodynamics concepts. (MLH)

Describes the advantages and disadvantages of a college program that leads to both a degree in physics and a teacher's certificate. (MLH)

Describes a student computer experiment that shows how the properties of the star, the temperature, and the opacity determine the nature of the observed spectrum of a star. (MLH)

Presents preliminary findings of results of tests of Piagetian cognitive development to predict success in introductory undergraduate physics courses. Grades were predicted with good success. (SL)

Presents the results of a survey of English physics teachers concerning the percent of classroom time they spend in practical work, the objectives of practical work, and their use of student projects. (MLH)

Discusses the philosophy and organization of an introductory college physics course that emphasizes laboratory experiments. Also presents a brief outline of the laboratory work. (MLH)

Describes an introductory laboratory physics course covering dynamics, fields, and waves. The course involves six hourrs of laboratory work and six hours of self-study every two weeks. Understanding concepts rather than laboratory techniques is stressed. (MLH)

Describes a laboratory teaching technique in which a single topic (in this case, bipolar junction transistors) is studied over a period of weeks under the supervision of one staff member, who also designs the laboratory work. (MLH)

Presented is information to supplement elementary physics texts so that teachers may expand the presentation of classical optics to include some basic concepts related to photographic systems. (SL)

Describes an experiment in which videotaping and classroom verbal rating systems were used to induce more higher level questioning by instructors in introductory physics laboratories. Concludes that teacher behavior can be modified or changed by setting instructional goals then receiving feedback. (MLH)

Students perception of the social learning environment in secondary school science courses were examined. The different environments that were perceived within the individual science courses and results, examined in light of student interest in science, are discussed. (BT)

Presents laser demonstrations of the surface photoelectric effect and the measurement of the laser beam wavelength; recommended for teaching the relationship between light energy and wavelength. (MLH)
