Describes the hardware and some of the choropleth mapping software available for the IBM-PC, PC compatible and Apple II microcomputers. Reviewed are: Micromap II, Documap, Desktop Information Display System (DIDS) , Multimap, Execuvision, Iris Gis, Mapmaker, PC Map, Statmap, and Atlas Map. Vendors' addresses are provided. (JDH)

The widespread availability of computational graphics for personal computers has greatly increased the potential for visual display of research data. The correlation between two variables can be represented graphically by using circles to represent the variance associated with each circle, and by letting the overlap between the circles be…

A brief package of subroutines (which can be typed in 15 minutes) enables a standard Apple II Plus, IIc, or IIe microcomputer to simulate a pen-plotter. Techniques for using this package in introductory engineering graphics courses are described. A sample program (which draws an oblique line) containing the subroutines is included. (Author/JN)

This book is designed to teach LogoWriter, a programming language. Each of the 41 small chapters focuses on a particular LogoWriter word or idea, and provides examples for practice and experimentation. Topics included are: (1) getting started with LogoWriter; (2) using repeat and label; (3) using color and random, shapes and stamp, fill and shade;…

Arguing that mathematics is a form of communication that students need help in understanding, this article describes a set of seven simple interactive LogoWriter tools that can be used to help children explore the language of multiplication. Examples of the use of graphics in responding to children's commands are provided and several exercises are…

Presents the listing (and documentation) for an arithmetic drill program with color graphics and sound. The program offers simple arithmetic problems illustrated by colorful dinosaurs. A buzzer sounds if an answer is incorrect while a short piece of dinosaur music is heard if an answer is correct. (JN)

This paper lists the commands for three programs in Logo: Peppy and the Maze, Caterpillars and Butterflies, and the Robot Arm. (EW)

This book helps individuals use Turtle Time Designs programs (i.e., a series of graphics program files to be used with LogoWriter) even if they have little previous experience with LogoWriter. The features of each program are carefully explained and are followed by step-by-step suggestions for teaching the lesson. Examples of the types of designs…

Presents various exercises and programs to demonstrate how low-resolution graphics (for Apple microcomputers) can be utilized in the mathematics classroom. (JN)

Discusses high resolution (hi-res) graphics programing on the Apple microcomputer, emphasizing its use in the mathematics classroom. Sample programs to plot dots and diagonals as well as programs for creating more complex visuals and patterns are included. (JN)

Presents the LOGO computer language as a source to experience and investigate scientific laws. Discusses aspects and uses of LOGO. Lists two LOGO programs, one to simulate a gravitational field and the other projectile motion. (MVL)

This report documents a computer-based gaming system for assessing recognition performance (RECOG). The game management system is programmed in a modular manner to: instruct the student on how to play the game, retrieve and display individual images, keep track of how well individuals play and provide them feedback, and link these components by…

Suggests having students design a football field (looking at it from above) as the final project of a unit on computer graphics. Includes listings for 13 short Applesoft programs (involving LO- and HI-RES graphics) which students can use in making the field. Advanced students can use the animation techniques. (JN)

Describes the derivation of the parameters incorporated into computer programs that are utilized to draw hypocycloids, which are the loci of points traced out by a point on a disk as it rolls against a circle and its interior. Includes information to obtain copies of the programs described. (JJK)

This collection of articles and features reprinted from "The Computing Teacher" begins with an outline (the table of contents) of a 20-session course, "Logo in the Classroom," by Shirley Torgerson, Mary Kay Kriley, and Janet Stone. The text of the first session and a student exercise sheet are also provided. Five articles…
