The use of the microcomputer in an interactive graphics mode offers exciting possibilities for mathematics and science education. Errors made with graphs are used to introduce ideas of what should be taught. Both understanding equations and graphing utilities are stressed. (MNS)

Outlines steps to follow and recommends special features when selecting equipment for an engineering computer graphics laboratory. Expansion features are also discussed. Provides a systems checklist for software and hardware. (CS)

Discusses the use of orbital shapes for instructional purposes, emphasizing that differences between polar, contour, and three-dimensional plots must be made clear to students or misconceptions will occur. Also presents three-dimensional contour surfaces for the seven 4f atomic orbitals of hydrogen and discusses their computer generation. (JN)

Describes 10 computer programs used to draw diagrams usually drawn on chalkboards, such as addition of three vectors, vector components, range of a projectile, lissajous figures, beats, isotherms, Snell's law, waves passing through a lens, magnetic field due to Helmholtz coils, and three curves. Several programming tips are included. (JN)

A Macintosh microcomputer and MacPaint program can be used to quickly make charts of structural formulas that fill standard-sized paper with a minimum of instruction, and smaller drawings or structures or fragments may be inserted into text composed with a word processing program. Shows how this is done. (JN)

This is the first of a two-part series on the general concept of vector space. Provides tool procedures to allow investigation of vector properties, vector addition and subtraction, and X and Y components. Lists several sources of additional vector ideas. (JM)

Describes graphical solutions of equations for stirred-tank reactors in series; data management software for producing and searching customized mass spectral libraries; least squares and chromatography programs; a low-cost data acquisition system for Apple microcomputers; nuclear magnetic resonance interpretation with graphics; chemical bonding…

Procedures for displaying computer-generated text and graphics to a large audience are inexpensive when a Fresnel-mirror projector is used. Although small liquid-crystal displays (LCDs) can be easily projected, large LCDs require some modification (which is described). Other devices with LCD displays (oscilloscopes, televisions, and pulse-height…

Presented is an example of this use of spreadsheet software. The basic case is considered with an extension and suggestions for other applications. Emphasized is the use of this method at the introductory level. (CW)

Discusses in detail the intricate and fascinating series of problems surrounding the production, distribution, and extended use of lessons in marine sciences that utilize remotely sensed images as the underlying medium of instruction. Focuses on computer-based learning activities because remotely sensed images are derived from the interpretation…

Liquid crystal displays are currently utilized to convey information via graphic displays. Presents experiments and explanations that employ the concept of liquid crystals to learn concepts related to the various states of matter, electric and magnetic forces, refraction of light, and optics. Discusses applications of liquid crystal technology.…

Discusses the need to take into account the effects of arrested fractional crystallization in the petrographic classification of volcanic rocks containing plagioclase phenocrysts. Describes the development and use of a computer program to accomplish this task graphically. (TW)

Cites advances in x-ray diffraction, nuclear magnetic resonance, computer modeling, and display to guide the design and analysis of protein structures. Reviews recent advances in knowledge, synthesis techniques, and theory of proteins. (JM)

Discusses three trends in computer-oriented chemistry instruction: (1) availability of interfaces to integrate computers with experiments; (2) impact of the development of higher resolution graphics and greater memory capacity; and (3) role of videodisc technology on computer assisted instruction. Includes program listings for auto-titration and…
