Briefly outlines the theoretical basis of the phenomenon of photoconductivity and describes a simple experiment which demonstrates the photoconductive properties of cadmium sulfide. (JR)

Discusses uses of the process approach to teach problem solving techniques to education students enrolling in a noncalculus physics course. Indicates that the prospective teachers are given opportunities to do real problem solving with the hope that they can foster in secondary school youngsters a better inquiry approach to science. (CC)

Describes the developmental cycle of the Copernican revolution as a swinging pendulum of philosophical and historical interpretation of views of the nature. Indicates that the paradigm shift'' in science results from interactions between scientific evidence and man's expectations of what the universe should be like. (CC)

Discusses Einstein's views on the role of Michelson-Morley, Fizeau, and Miller experiments in the development of relativity and his attitude toward the theories of new quantum mechanics. Indicates that Einstein's opposition to quantum mechanics is beyond dispute. (CC)

The roots of new physics courses are considered and doubts raised about them particularly when they are addressed to problems of society. A new, career-oriented undergraduate major on technology and man is then suggested. To illustrate its content, a course on urban transportation is described in detail. (BL)

Increasing the flexibility of a well equipped laboratory by eliminating rigid scheduling gives students a choice of experiment and allows them to do experiments in depth. Student motivation, interest, and learning were increased. (DF)

An experiment assigned in a role-playing'' modern physics lab for juniors who are challenged to obtain accurate measurement with suboptimum apparatus through correct analysis. They also investigate the influence of systematic errors using a small computer. (DF)

A student method for the calculation of the electron wavefunction in a central-field potential using the technique of numerical calculation of stationary state solutions. (DF)

Describes a physics laboratory course which operates without written instructions and with no required experiments. Course is based upon one- or two-week topics in mechanics, heat, electromagnetism and optics with a student-designed experiment in modern physics as an extended project. (DF)
