The range of subjects taught by physics probationary teachers in the academic year 1987/88 in the United Kingdom is examined. The implications of the data are discussed in the light of teacher shortages and the initial education of science teachers. Lists 12 references. (YP)

Discusses the making of a light engine powered by sunlight or a lamp. Describes the materials and construction method with detailed specifications and diagrams. (YP)

Discusses some historically important reference systems including those by Newton, Leibniz, and Galileo. Provides models illustrating space-time relationship of the reference systems. Describes building models. (YP)

Discusses the use of saline solutions for demonstrations of buoyancy showing oscillations of the Cartesian diver. Describes the physical principles, preparation, and instructional uses for the demonstration. (YP)

Cites the misconceptions that students beginning the study of electric circuits often have about electricity. Explains the use of capacitors with circuits of batteries and light bulbs to introduce electrostatic forces and help to alleviate the problem of misconceptions. (RT)

Discusses the implementation and evaluation of the first full year of college freshman integrated natural science curriculum. Identifies separate courses in chemistry and biology as the foundation with physical principles as the unifying theme. Notes all instructors attended all classes. (MVL)

Discusses three aspects of electrochemical detectors: (1) signal and noise generation and signal-to-noise ratio, (2) improvement of qualitative information content, and (3) control of selectivity of the detector. Explains electronic principles of detectors and detection limits. Lists current applications and research. (ML)

Discusses the possibilities of accelerating the rate of cognitive development and describes the design and trial of intervention lessons. Gives preliminary results from one laboratory school indicating that the possibility of accelerating general cognitive development is worth pursuing. (YP)

Evaluates 16 commercially available courseware packages covering topics for introductory physics. Discusses the price, sub-topics, program type, interaction, time, calculus required, graphics, and comments of each program. Recommends two packages in measurement and vectors, and one-dimensional motion respectively. (YP)

Described are developments in medical electronics and physiological measurement. Discussed are electrocardiology, audiology, and urology as mature applications; applied potential tomography, magnetic stimulation of nerves, and laser Doppler flowmetry as new techniques; and optical sensors, ambulatory monitoring, and biosensors as future…

Discussion of how visual analogies aid students' understanding of math and science focuses on new types of representations that use computers. Topics addressed include understanding and cognitive performance; the role of representations in understanding, including examples; evidence of instructional effectiveness of new representations; and…

Administered a laboratory process skills test to 147 year-5 students to assess their investigations, performance, and reasoning in biology, chemistry, and physics. Reports significant correlation between performance and amount of homework done and students' perceptions of several aspects of the classroom environment including personalization,…

Describes a case study of an advanced physics class that analyzes the implications of using computerized journalizing. Reports that this technique provides a vehicle for students and teachers to make their knowledge public, builds an atmosphere for valuing the conceptual understanding of others, and mediates an ongoing dialog between the…

This paper presents cognitive and social data on 134 gifted students at a Moscow (Russia) residential math/physics high school. Three case studies of students frequently selected by students in a sociometric task are detailed. Discussion focuses on effects of lack of emphasis in humanities and social sciences, and on social and gender issues. (DB)
