Discusses the definition of energy found in many high school and college level physics texts, the conflict of that definition with the second law of thermodynamics, and the relation to the concept of the conservation of energy. Suggests not using a definition of energy and provides some alternative strategies. (JM)

Interviews were conducted and tests were administered to determine if students found chemistry or physics easier. Reasons for their choices (including the fact that physics was perceived as relating to the life/world domain) and type knowledge used by the students are discussed. (JN)

Suggests that ideal experiments fit into course time constraints and be meaningful, relevant to course content, safe, inexpensive, simple, reproducible, and easy to set up/maintain. Describes a Boyle's Law experiment that uses a minimum of equipment and meets the foregoing criteria. Apparatus used, procedures, and safety precautions are…

Discusses the construction of various types of physics equipment from laboratory "bits and pieces" (parts of discarded/unusable equipment). Includes comments on constructing improvised equipment from similar bits and pieces in schools in Peru and the Caribbean. (JN)

Describes an experiment enabling students to apply concept of diffraction, determine limits of their color perception, learn how to measure wavelength with a simple apparatus, observe continuous and line spectra, and associate colors with corresponding wavelengths. The homemade diffraction-grating spectrometer used is easily constructed. (JN)

Describes inexpensive method of determining harmonic content of a repetitive signal such as a sound wave and demonstrations of the precession of a bicycle wheel and inversion shadows on the retina. Also describes a resonance demonstrator (made from scrap material) driven by a portable jigsaw. (JN)

Trends in science teaching equipment include digital instrumentation and use of microcomputers as general purpose laboratory instruments. Describes interface units which exploit this capability of the microcomputer. Also describes materials supporting the teaching of electronics. (JN)

Reports results of an informal questionnaire sent to university physics departments (N=33) to determine attitudes towards Nuffield and traditional A-level physics. Concludes that Nuffield students perform better at practical work, universities prefer the traditional background, and Nuffield students lack mathematics skills. (DC)

Discusses three avenues of problem-solving research: misconceiving natural laws, processing information, and constructing solutions. Suggests that the change in emphasis from problem to problem solver and the key role of "physics" problems are unifying aspects of the research. (JN)

Funds (1983) for National Science Foundation (NSF), National Aeronautics and Space Administration (NASA), and Environmental Protection Agency (EPA) research programs include $1,092,200,000 (NSF), $5.5 billion (NASA), and $119 million (EPA). NSF's science education activities were raised to $30 million in spite of the Administration's plan to phase…

Three different simulation and gaming techniques are described in detail as examples of exercises that provide education through science, demonstrating how science and technology fit into the broad political, social, and environmental context. These games and simulations also cultivate useful skills and desirable attitudes. (Author/JN)

Presents data on student performance in a competency-based, multiple-opportunity format physics course, indicating that costs are related to character of examination questions and comprehensional modes of students. Compares costs for single/multiple trial formats, showing that multiple-trial opportunity has lower costs and a higher yield of…

Mineralogy has become increasingly linked to chemistry and physics during recent years. This relationship between chemistry, physics, and mineralogy, as indicated by the content of conference papers, research studies, and physical/chemical laboratory procedures used in mineralogy, is reviewed. Creative applications of established mineralogic…

Describes a demonstration to initiate discussion about electrostatic effects. Also describes and evaluates a Magnetic Bubble Apparatus, a device which exhibits several phenomena related to magnetic domain formation. Includes manufacturer's response to the evaluation. (JN)
