Selected structure-of-intellect factor measures were compared with subtests of the Florida State-Wide Twelfth Grade Test in predicting physics achievement. Multiple correlation coefficients were approximately the same when both sets were used together to predict physics achievement. (Author/PN)

Presents and discusses results of a questionnaire survey of college/polytechnic students (N=213) on their perceptions of and motivation for embarking on a combined-degree physics program. Areas/topics addressed include course structures of responding colleges/students, entrance requirements, student background, reasons behind choice of first year…

Traces the history and development of the physics textbook from 1870-1980. Areas discussed include extrinsic (bibliographical and biographical components) and intrinsic textbook properties. Among topics considered in the latter are subject structure and content, indicating a concern related to excess text material over syllabus requirements. (JN)

Discusses several practices in teaching physics that are of dubious merit, such as stressing vocabulary and stressing content over process. Suggests several alternate approaches to make physics teaching more interesting. Includes several issues affecting the quality of science education which involve general school policy. (JN)

The main problem in constructing functioning electric motors from simple parts is the mounting of the axle (which is too flimsy to maintain good electrical contacts or too tight, imposing excessive friction at the supports). This problem is solved by using a pencil sharpened at both ends as the axle. (JN)

Describes several outstanding high school physics programs and analyzes the reasons for their success. This analysis suggests a set of conditions for creating successful programs at other schools. A list of goals for successful physics programs is included. (JN)

When salt (NaCl) is introduced into a colorless flame, a bright yellow light (characteristic of sodium) is produced. Why doesn't the chlorine produce a characteristic color of light? The answer to this question is provided, indicating that the flame does not excite the appropriate energy levels in chlorine. (JN)

In November 1982, 10 college physics teachers visited universities and other sites in the People's Republic of China. Discusses this tour, focusing on the quality of life in China and physics at Chinese universities. The latter discussion includes various aspects of physics curriculum, instruction, and research. (JN)

Lists physics courses at universities and colleges of technology in Scotland. Includes honors degree courses, course structure, special entry requirements (if any), special notes, and name of contact person. (SK)

Presents results of a survey on physics teachers' opinions of microcomputers and microprocessor-based teaching aids they have used, including what features were considered most important and advantages/disadvantages of and personal comments about each device. Includes a glossary of terms used in the report. (JN)

Basic concepts associated with seismic wave propagation through the earth and the location of seismic events were explained in part 1 (appeared in January 1983 issue). This part focuses on the construction of a student seismometer for detecting earthquakes and underground nuclear explosions anywhere on the earth's surface. (Author/JN)

Discusses the concepts of energy, flow of energy through ecosystems in which people live, our increasing use of energy as society evolves, and the importance of energy to all societies. A chart listing advantages/disadvantages of various energy sources is included. (JN)

Photoelectrochemistry is based on the semiconductor electrode. It is the semiconductor's ability to absorb light and convert it to electrical and/or chemical energy that forms the basis for the semiconductor liquid-junction solar cell. To understand how this occurs, solid-state physics concepts are discussed. (Author/JN)

The use of semiconductors as electrodes for electrochemistry requires an understanding of both solid-state physics and electrochemistry, since phenomena associated with both disciplines are seen in semiconductor/electrolyte systems. The interfacial energetics of these systems are discussed. (JN)

Describes five physics demonstrations using inexpensive and easily obtainable materials. Demonstrations include: (1) sinking ice cubes and diffusion; (2) returnable can; (3) persistent currents in a liquid; (4) light scattering by milk particles; and (5) rotation of a plane of polarization. (JN)
