Describes an application of solid-state memories in a laboratory course, which enables students to build electronic devices. Also introduces the fundamentals of analog-to-digital conversion and sampling theory. (CS)

Presents a 52-item bibliography of works in the ERIC collection dealing with science instruction at two-year colleges. The entries cover the areas of general science, agriculture, biology, chemistry, earth science, economics, engineering, environmental sciences, interdisciplinary sciences, social science, mathematics, physics, psychology, and…

Outlines a variety of laboratory procedures, discussions, and demonstrations including a no-solder circuit board, damped to maintained oscillations with L-C circuits, polaroid strobe photos, resistive putty, soldering and circuit checking exercise, electromagnetic radiation, square pulses in C-R circuits, and testing an oscillating system. (GS)

Presents arguments for and against the viewpoint that the teaching of chemistry and of physics should fall in line with modern mathematics. Concludes that modern mathematics has been beneficial in some respects and harmful in others. (CS)

Focuses on (1) the current crisis in physics teaching in secondary schools and colleges due to decreases in student enrollment, and (2) the growing shortage of secondary school physics teachers. Discusses reasons for the crisis and presents an approach to solve this problem. (SK)

Describes method for locating images in simple and complex systems of thin lenses and spherical mirrors. The method helps students to understand differences between real and virtual images. It is helpful in discussing the human eye and the correction of imperfect vision by the use of glasses. (Author/SK)

Reports the results of a survey of practicing scientists, recent graduates, and undergraduates about their perceptions of undergraduate laboratory programs in biology, chemistry, and physics. Scientists and graduates regard laboratory experiences in pragmatic terms stressing the scientific process skills while undergraduates regard laboratories as…

Describes the use of a microcomputer in studying a model experiment (Brownian particles colliding with thermal particles). A flow chart and program for the experiment are provided. Suggests that this experiment may foster a deepened understanding through mutual dialog between the student and computer. (SK)

Discusses the development of a curriculum in physics and biology designed to help prepare academically disadvantaged college students, most of whom are members of racial or ethnic minority groups. Reasons are given for addressing concept formation and reasoning development together, and for direct experience preceding discussion of formal…

Summarized are the key features of the revolution in electronics, namely (1) capacity, (2) cost, (3) speed, and (4) size. Outlined also are some possible implications for the future with particular reference to telecommunications, medical services and education. (CS)

A lesson from a physics textbook for secondary students was redesigned in three versions and given to 600 students. Results of achievement measures suggested that one of the experimental versions (which stressed the visual aspects of the printed page) was superior to the standard and the other experimental versions. (GT)

Discusses how the British Post Office is using the Prestel information retrieval system. The information structure adopted for the Prestel databases and how the Prestel system hardware works are presented. Computer system software, types of information, and the impact of Prestel system on society are also presented. (HM)

Discusses three research topics which are concerned with eminently practical problems and deal at the same time with fundamental fluid dynamical problems. These research topics come from the general areas of chemical and biological engineering, geophysics, and pure mathematics. (HM)

Explains that education and research, after having been neglected during the Cultural Revolution in China, are once again receiving emphasis, aided by extensive reading and by the reprinting of Western scientific literature. (Author/GA)

An experiment for senior college undergraduate physics students is described. Amorphous tungsten trioxide films are suggested for use since they have a unique electrochromic system. (Author/SA)
