An activity in which students combine physical and mathematical principles in a measurement situation is described. (SD)

Reports that expenditures per physicist for basic research dropped 40 percent between 1966 and 1974 at United States academic institutions that bestow the doctoral degree. (CP)

Presents an undergraduate laboratory exercise in elementary statistics in which students verify empirically the various aspects of the Gaussian distribution. Sampling techniques and other commonly used statistical procedures are introduced. (CP)

Presents seven science experiments and activities for the junior high school level relating to electrostatics, electronics, magnetism, electricity and other areas of science. (HM)

Describes a Keller Plan program for teaching thermodynamics to college students. The outcome is improvement in study habits, and a more positive attitude towards examinations, but less performance in problem solving ability than via traditional approach. (Author/GA)

Describes a teaching module on special relativity in which priority is given to attitudinal objectives as opposed to objectives of content. Explains the implications of this for methodology and course structure, and discusses the course material together with some conclusions and evaluations of the module. (Author/GA)

Describes the objectives, the procedures, and the evaluation involved in a personalized system of instruction (PSI) that has been introduced, as an option and as an alternative, in teaching a general physics course at Purdue University. (GA)

A gas pressure gauge has been constructed for use in a student experiment involving the law of atmospheres. From pressure data obtained at selected elevations the average mass of air molecules is determined and compared to that calculated from the molecular weights and percentages of constituents to the air. (Author/BB)

This is the second of several papers which attempts to introduce group representation theory to students of molecular or solid-state physics in as intuitive and simple a fashion as possible. (Author/BB)

Describes a modified experiment to measure the internal resistance of an energy source, where a small resistance is connected in series with the source. (GA)

Describes a study of 708 eleventh and twelfth graders of cognitive development and their ability to learn physics. The theories of Piaget were used as a model to study the teaching and learning of physics. (MDR)

Investigates the prevalence of developmental cognitive differences among college students and the relation of scores on cognitive tests to an objective form of assessment of achievement, namely, the final grade in a conventional physics course. (GA)
