Presents the results of a series of studies on the production, transformation, and interpretation of graphical representations from grade 8 to professional scientific practice in formal testing situations (inside) and in the course of field/laboratory work (outside). (Author/CCM)

Explores the subject of fractal geometry focusing on the occurrence of fractal-like shapes in the natural world. Topics include iterated functions, chaos theory, the Lorenz attractor, logistic maps, the Mandelbrot set, and mini-Mandelbrot sets. Provides appropriate computer algorithms, as well as further sources of information. (JJK)

This paper describes Macintosh features which can be used in writing interactive programs. A program written in Microsoft BASIC (version 2.0 interpreter) is described which is used to produce plots of electric field produced by two-dimensional arrangements of point charges. It demonstrates the use of pull-down menus, windows on the screen, the…

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…

The graphics and animation capabilities of computers offer a new dimension in science testing. Instead of presenting verbal situations or questions with accompanying pictures, computers can present simulated actions and events that are the focus of science questions. The purpose of this project was to develop a valid and reliable computer-based…

Discusses various ways science can be taught using microcomputers, including simulations/games which allow large-scale or historic experiments to be replicated on a manageable scale in a brief time. Examples of several computer programs are also presented, including "Experiments in Human Physiology,""Health Awareness…

Described is a computer program which accepts face data, performs all necessary symmetry operations, and produces a drawing of the resulting crystal. The program shortens computing time to make it suitable for online teaching use or for use in small computers. (Author/DC)

Reviews a software package, "Mitosis-Meiosis," available for Apple II or IBM computers with colorgraphics capabilities. Describes the documentation, presentation and flexibility of the program. Rates the program based on graphics and usability in a biology classroom. (CW)

A hypermedia computer program that uses text, graphics, sound, and animation with associative information linking techniques to teach the functional anatomy of a rat is described. The program includes a nonintimidating tutor, to which the student may turn. (KR)

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.…

Describes experiences with turtle graphics to demonstrate motion in a constant gravitational field. Provides the computer program and typical diagrams. (YP)

Described are eight microcomputer systems that are suitable for computer-aided instruction (CAIDI) in chemistry. Specific instructional applications are described to illustrate the wide variety of systems available and their adaptability to problems faced by chemistry teachers. (BT)

Describes an experimental setup using a microcomputer for demonstrating the circadian movement of petioles. Discusses experiments that were performed using this apparatus and factors that relate to these plant movements. Includes graphs that have been obtained. (CW)

Describes a microcomputer program that simulates the pattern of evolution and produces clade diagrams and summary statistics. Allows users to vary the odds affecting the fate of a species. (TW)

Discusses some of the attributes of effective tutorial software programs. Describes four science programs that focus on the physical and earth sciences, and highlights some of their features that are proposed as features of high-quality educational software. (TW)
