Describes a microcomputer-based, multichannel digital data acquisition system for acoustic signals. Hardware and software considerations are included. (JN)

An interactive, instructional videodisc was produced using films on wave motion/vibrations and Tacoma Narrows bridge collapse. The disc is appropriate for three levels of physics (physics/algebra; physics/calculus; non-major physics). Program sections (introduction to videodisc player, bridge collapse, influence of wind, bridge properties, and…

Defines all recurrence relations used in the Nuffield course, to solve first- and second-order differential equations, and describes a typical algorithm for computer generation of solutions. (Author/GA)

Discusses stages in the evolution of educational software and changes in general and specific software characteristics. Also discusses future developments in educational software and hardware, suggesting the development of a new area in educational and cognitive psychology centering on computers in education. (JN)

Advantages of computerized data acquisition and three approaches to data collection are discussed. Interfacing techniques and use of microcomputers as physiological recorders are also discussed. Examples of computerized data acquisition are provided. These include computer monitoring of animal activity and collecting data from species distribution…

Describes: (1) two experiments using a laser (resonant cavity for light and pinhole camera effect with a hologram); (2) optical differaction patterns displayed by microcomputer; and (3) automating the Hall effect (with comments on apparatus needed and computer program used); and (4) an elegant experiment in mechanical equilibrium. (JN)

Provided is an annotated list of 27 computer-oriented publications (magazines and journals). Annotations include nature/scope of publication, source, 1983 cost, and when applicable, comments on potential classroom use(s). Also indicates that information in the publication is directed toward a specific audience/computer or of general interest. (JN)

Suggests using musical instruments to demonstrate physics concepts. Topics include: pitch and frequency; string vibrations; string-resonator system; wind instruments; harmonic content; transients; scales and temperament; psycho-acoustical affects; and electronic music. (SK)

The first part of this paper addresses the following topics: (1) the usefulness of microcomputers; (2) applications for microcomputers in analytical chemistry; (3) costs; (4) major microcomputer systems and subsystems; and (5) which microcomputer to buy. Following these brief comments, the major focus of the paper is devoted to a discussion of…

Describes the Interactive Microcomputer Peripheral (including major features, source, and current cost) and physics experiments using the instrument. The instrument can also be used for such purposes as counting, timing, and frequency measurement as well as for experiments in biology and experimental psychology. (JN)

Describes two computer programs in which students select chemical substances and amounts for use on an imaginary trip. Written in BASIC, the 400-statement program is suitable for use on microcomputers. (SK)

Describes the use of microcomputers in data acquisition and simulation of physical phenomena. Discusses digital and analog inputs/outputs, simulations, and interactive programs in mechanics. Includes examples of computer programs. (SK)

Outlines different ways to use microcomputers in science laboratories: (1) as electronic blackboards (simulations, data presentation, number crunching); (2) as universal laboratory instruments (control technology, sound output, time measurement, digital-analog conversions); (3) for educational management; and (4) for computer assisted learning.…

Described are developments in medical electronics and physiological measurement. Discussed are electrocardiology, audiology, and urology as mature applications; applied potential tomography, magnetic stimulation of nerves, and laser Doppler flowmetry as new techniques; and optical sensors, ambulatory monitoring, and biosensors as future…
