An effective approach to drawing instruction at the secondary level is through the exploration of unique materials and techniques. Two such approaches involve the use of physics and aesthetics--creations of drawings utilizing photographic processes. Methods of teaching direct light drawing and etched light drawing are presented. (Author/KC)

The abilities to understand medical technology, to evaluate new devices and procedures, and to assess their effectiveness, reliability, costs, and risks in comparison with existing methods are discussed. A course in clinical biophysics offered at the State University of New York at Buffalo is described. (Author/MLW)

Presents a simple introduction to the fundamental physical ideas involved in the breaking of local gauge symmetry. The purpose of this article is to show how these ideas can be understood independently of any particular application. (Author/HM)

Relates the impressions of science education gained by a physics professor visiting the People's Republic of China. Observations from two universities in Beijing and Wuhan provide information regarding departmental organization, general teacher preparation, preuniversity education, science teacher preparation, specific physics departments, applied…

Describes an apparatus to be used in a visual presentation of simultaneous, independent motions and their resultants. The apparatus is best suited for representing a boat and stream, but could be modified to represent a plane in a moving air mass. (Author/DS)

Presents a play or dialog appropriate for beginning college students that introduces some basic ideas regarded as part of Aristotelian physics. (CS)

Discusses physics teacher competencies and their emphasis in the development of a physics teacher education program in Dortmund, Germany. (CS)

Presents two experimental set-ups. The first demonstrates the law of Malus using a pair of Polaroid polarizers and a monochromatic light source with an interference filter. The second describes a modification of Hilton's apparatus to demonstrate the effects of the magnetic hysteresis on an overhead projector. (CS)

Presents nine physics notes for British secondary school teachers. Some of these notes are: (1) speed of sound in a steel rod; (2) physics extracts-part four (1978); and (3) a graphical approach to acceleration. (HM)

Describes a two-semester physics course developed at the University of Alberta, Canada to present the development of some of the major theories in physics and their interaction with the prevailing cultures, religions, and philosophies. (HM)

Describes some undergraduate laboratory experiments in acoustics which involve the analysis of speech and musical instrument sounds and the general analysis of the frequency range of complex sounds. (HM)

Discusses some physical principals that can be used to understand the proper ties of Portland cement and concrete. (HM)

Describes an applied physics course which has been taught at Liverpool Polytechnic in the United Kingdom. Objectives, experimental work and assessment of the course are included. (HM)

Provides a simple method for finding the values of the total angular momentum J for configurations of equivalent electrons in jj coupling. Shows how a knowledge of both the LS and jj terms can contribute to the students' understanding of the role of different representations in quantum mechanics. (Author/GS)

Derives an expression for the orientational entropy of a rigid rod (electric dipole) from Boltzmann's equation. Subsequent application of Newton's second law of motion produces Debye's classical expression for the relaxation of an electric dipole in a viscous medium. (Author/GS)
