This article examines: (1) some difficulties associated with teacher interaction analyses, (2) well known teacher interaction scales, (3) current directions in research and practice in observation, and (4) special applications of teaching interaction analyses to the field of physics. (CP)

Presents Unit Nine Change and Chance of the Nuffield Advanced Physics, dealing with energy conservation, and a novel statistical approach to diffusion, thermal equilibrium and thermodynamics. Information about energy resources, alternative sources of energy, and energy-cost of materials are also presented. (HM)

Presents a classroom demonstration that illustrates the Law of Conservation of Energy. The demonstration utilizes a coupled pendulum device that can easily be constructed from ordinary monofilament fishing line and two metal pendulum bobs. (HM)

Compares two teaching forms of an introductory laboratory course in physics. Concludes that the individualized version is more efficient in learning time and, on the whole, more effective than the traditional version, even though the latter one seems to reinforce student's existing positive attitudes towards physics experimentation. (Author/GA)

An interdisciplinary laboratory course is described in which the experimental methodology of physics is applied to problems of potential research interest to the nonphysicist. Special attention is given to those practical considerations which determine the structure and content of such a course with particular emphasis on the unique pedagogical…

As part of a senior high school physics unit on nuclear power, changes in student attitudes toward nuclear power plants and problems of energy supply were analyzed. Tests included a situational test, semantic differentials, knowledge or achievement, and a final questionnaire. The results are discussed. (CTM)

Describes a laboratory demonstration to show how to determine the focal length of a thin glass lens under water. (GA)

A remedial self-study course in physics has been successfully developed at Nottingham University through repeated evaluations and modifications in such areas as testing and course organization. The development of a self-instructional center, and the use of film and videotape packages, have also been successful. (JMD)

Describes a physics course where students visit industrial and government scientific research laboratories. The aim is to familiarize the students with research tools available, and to make them understand the potentials, limitations, the functioning principles, and the design features of the instruments. (GA)

Explains a demonstration that shows the additive nature of light using three overhead projectors. (GA)

Compares the Ausubelian approach and the traditional one to the content organization of an introductory course in electromagnetism. States the differences between these approaches in terms of the student's ability to apply, relate, and differentiate electromagnetic concepts. (GA)

Describes in detail the construction of an improved version of Hero's engine that is easy to operate and has a short response time. (GA)

Presents fifteen selected physics notes which could be used in school physics courses. Each includes the name of the author and a description of activities suggested. (HM)

The use of chemical properties of metals and water via outer electron behavior models for instruction in science is presented. (MDR)

The modular degree program in physics at Oxford Polytechnic is described. This program allows for a combination of physics with other undergraduate study areas. (MDR)
