Discusses the construction of lenses made out of ice, including the arrangement for mounting an ice lens on a camera. Also discusses brewing coffee in an ibrik (long-handled container tapering slightly toward the top), focusing on the physics of the brewing. (JN)

Investigated relationships between physics achievement and language of instruction where instruction was in the second language of both students and teachers. Grade 10 subjects (N=176) studied light/sound in either Chinese (N=90) or English (N=86). No differences in achievement, students' motivation, and time spent in physics were found.…

Topics include: (1) the content, style, and level of physics' textbooks; (2) suggestions for in-class use; and (3) recommendations for upgrading current texts. (SK)

An elementary formalism is developed for representing curved space-time which allows transparent qualitative explanation of general relativistic effects and is used to make a conceptual analysis of Einstein's principle of equivalence. A final section outlines a number of student activities. (Author/SK)

Presents some general characteristics of "older" students and describes courses and instructional strategies in the physical sciences related to these characteristics. (SK)

Examples of the application of compound pendulum theory to the practical measurement of the moments of inertia of human beings, farm tractors, and sailing boats are presented. Suggests developing laboratory experiments to measure moments of inertia of hockey sticks, golf clubs, and frisbees, among others. (Author/SK)

Experienced Physicists solve simple textbook problems differently from beginning students. This paper describes these differences using a computer-implemented model that "learns." The research is set in the the context of modern computer-processing psychology, and is related to other work relevant to help people know and learn…

Provides rationale for and examples of a game (Mastermind) which fosters the development of a systematic approach to problem solving. Includes a brief summary of an experiment with 50 high school students indicating value of the game. (JN)

Describes a study which determined the prevalence of the non-Newtonian view among students (N=125) and to what extent their physics teachers (N=5) were aware of this prevalence. Includes methods used and summaries of typical responses to a paper-pencil, multiple-choice format questionnaire focusing on aspects related to force. (JN)

Following a description of the "options" component of the JMB A-level physics syllabus, teachers' responses to these options are summarized by considering the time taken to complete options, factors influencing choice of options, and options teachers felt they knew best. (JN)

Refutes scientific creationists' arguments that the earth is less than 10,000 years old by presenting information related to the time scales for creation and evolution models, times from stellar distances, Kelvin's estimate of the earth's age, radioactive decay, radiometric dating, and the decay of the earth's magnetic field. (DC)

Argues that research for teacher use would be more effective if it were: (1) of the form referred to as naturalistic case studies and (2) oriented toward discovering cognitive and social interaction mechanisms underlying the learning processes in classrooms. (Author/SK)

Presents excerpts of an interview with Philip Morrison, Institute Professor of Physics at M.I.T., who has made significant contributions to areas ranging from high-energy astrophysics to elementary school science education. (Author/SK)

Data gathered from a national survey mailed to 55 industries employing large numbers of technical personnel support the notion that the employment market should be broadened for persons receiving their academic training in physics. Alternative curriculum strategies and course subjects are suggested for preparing physicists for industrial…

Describes a Simple Huckel Molecular Orbital (SHMO) computer program written in BASIC and suitable for use on a variety of common microcomputers. (SK)
