A complete matrix formulation of the theory of small oscillations is presented. Simple analytic solutions involving matrix functions are found which clearly exhibit the transients, the damping factors, the Breit-Wigner form for resonances, etc. (BB)

Some of the properties of electromagnetic showers observed in an experimental study are illustrated. Experimental data and results from quantum electrodynamics are discussed. Data and theory are compared using computer simulation. (BB)

An introduction to the Personalized System of Instruction (PSI) and its use in engineering education. (BB)

Examines American and British policies concerning DNA research and gene transplantation. (CP)

Results of tests administered after one year of college chemistry do not reveal significant differences between students enrolled in the Keller plan of personalized instruction and those students in traditional lecture-discussion instruction. (CP)

Examples are provided of a method of successive approximations suitable for use in a freshman level chemistry course. (CP)

College-level chemistry questions and satisfactory answers are provided. (CP)

Detailed instructions for use in an undergraduate level course are provided. (CP)

Explains a laboratory experiment dealing with the optical features of the human eye. Shows how to measure the magnification of the retina and the refractive anomaly of the eye could be used to measure the refractive power of the observer's eye. (GA)

Presents a quantitative laboratory experiment in geometrical optics. It involves the student in the measurement of the radius of curvature of the cornea and is based on an old method devised by Kohlrausch in 1839. (Author/GA)

Presents the results of two experiments concerning the phenomena of the interference of probabilities and of the so called Aharonov-Bohm effect. An electron biprism and a standard electron microscope have been used for the experiments. (Author/GA)

Explores the problem of how to determine standards of performance for energy conversion processes. Argues against infinitely slow reversible processes as standards, and explores simple and faster alternative processes. (Author/GA)

Explains a modified approach to PSI physics courses, where group interaction takes place through problem solving sessions held on a regular basis, and which the students are required to attend. (GA)

Describes the organizational structure of the National Science Foundation, focusing chiefly on the Science Education Directorate and its three divisions--Science Personnel Improvement, Science Education Resources Improvement, Science Education Development and Research--and how to obtain grants from them for community college science education, as…

Reviews the use of the Personalized System of Instruction (PSI) in engineering education. (SL)
