Reports on a study of Canadian upper secondary science students' achievement of the concept of proportion. Results indicated that, in classes where the proportion content was emphasized by the teachers, higher achievement was demonstrated. (TW)

Describes a magic show designed to encourage young children in physics and chemistry. Discusses how a little "razzle-dazzle" can effect children positively. Tells how to organize and perform a magic show. Details six tricks that focus on principles of chemistry or physics. (CW)

Consists of the second part of the 1985 annotated review of technical books done by the Astronomical Society of the Pacific. This listing was primarily designed for graduate students or research scientists. (TW)

Describes the approach and programming emphasis of the National University of Distance Education (UNED). Specifically explains the university's summer residential workshops that focused on basic physics phenomena that were laboratory oriented. Includes examples of the course requirements and samples of the participants' opinions about the course.…

Presents 26 activities, experiments, demonstrations, games, and computer programs for biology, chemistry, and physics. Background information, laboratory procedures, equipment lists, and instructional strategies are given. Topics include eye measurements, nutrition, soil test tube rack, population dynamics, angular momentum, transition metals,…

Presents eight separate articles on science education. Topic areas addressed include: an inservice course in primary science; improving physics teaching; reducing chemistry curriculum; textbook readability measures; school-industry link for introductory engineering; local education authority initiatives in primary school science; and "Winnie…

Addresses the strategy and policy implications of effective ballistic missile defense and the scope/priorities of a research program underway to determine its technical feasibility. Several types of "smart bullets" are described, along with sensing devices for space, air, and ground. Procedures established to centrally plan/control the program are…

Secondary physics students were interviewed to determine their expectations/actions in laboratory work. Results indicate preference for laboratory activities because such exercises help students remember, are less confusing, and more concrete. Use of the laboratory as an introduction to a concept, followed by discussion, was a key component to…

A series of 12 reports on the Voyager Two experiments in the Uranian system. Reports are included on: (1) imaging science; (2) photometry; (3) infrared; (4) ultraviolet; (5) radio science; (6) magnetic fields; (7) plasma; (8) charged particles; (9) magnetosphere (hot plasma and radiation); (10) radion observations; and (11) plasma waves. An…

Describes an X-Y scanner used to create acoustic holograms. Scanner is computer controlled and can be adapted to digitize pictures. Scanner geometry is discussed. An appendix gives equipment details. The control program in ATOM BASIC and 6502 machine code is available from the authors. (JM)

Describes an experimental procedure to measure the specific heat of a gas. Discusses equipment, setup, and procedures and provides sample values obtained for air, propane, helium, carbon dioxide, and argon. (JM)

Presents a classroom experiment that demonstrates the directional sensitivity of the human ear. Outlines the activity's procedures and provides a diagrammatical view of the experimental arrangement. Also included is an analysis of the expected results. (ML)

Describes various resources for teaching problem-solving. They include: (1) several books with a problem-solving emphasis; (2) a workshop focusing on the attitudinal components of thinking and problem-solving; and (3) a summary of a study dealing with problem-solving in the context of high school physics. (JN)

A formative evaluation model was used to evaluate a physics curriculum for technical vocational high schools. The evaluation focused upon the curriculum materials; the student in the classroom, in small groups, and as an individual; students' conceptual frameworks; and students' ability to cope. (GDC)

Describes development of a generative schema based on the concept of change for inclusion in instructional materials for a college physics course to help students integrate all of the physics content. Psychological basis for these materials is discussed, a design approach is described, and questions are posed for further investigation. (MBR)
