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)

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)

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)

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 how color graphics are built up on microcomputer displays and how a range of colors can be produced. Discusses the logic of color formation, noting that adding/subtracting color can be conveniently demonstrated. Color generating techniques in physics (resistor color coding and continuous spectrum production) are given with program…

Explores the production of shadows for drawings using the LOGO computer language and Affine Geometry. Explains the methodology of the shadowing and lists the Affine Turtle procedures. Provides for different versions of LOGO. (MVL)

Describes a new software package for the Apple Macintosh computer which can be used to create elaborate simulation models in a fraction of the time usually required without using a programming language. Illustrates the use of the software which relates to water usage. (TW)

Describes how three dimensional LOGO was used in a workshop session for secondary pupils and mathematics teachers. Provides many commands and output drawings. (YP)

Instructional applications for NeXT computers were developed by nine faculty members from the biology, mathematics and computer science, fine arts, chemistry, physics and astronomy, and geology departments as part of a grant awarded to the California State University at Los Angeles. These notes provide a schedule of events and reports from a 2-day…

Discusses four applications of the microcomputer to the classroom: (1) a program listing of how to draw circles on the Apple II computers; (2) using a database to help write stories; (3) switching computers with others while writing stories to encourage creativity; and (4) a listing of a LOGO kaleidoscope program. (MVL)

Describes the Heat Exchanger Network Synthesis (HENS) program used at Worcester Polytechnic Institute (Massachusetts) as an aid to teaching the energy integration step in process design. Focuses on the benefits of the computer graphics used in the program to increase the speed of generating and changing networks. (TW)

Provides a listing of a software graphics program that investigates the law of reflection and Snell's law of refraction. Written in BASIC for the Apple II personal computer. (MVL)
