The major intent of this project was to design microcomputer lessons utilizing the unique features of computers to teach a high school mathematics topic. After reviewing the literature, it was decided to write a series of three tutorial lessons for a class in high school trigonometry which would present the concepts of amplitude, period, phase…

The use of microcomputers to aid geometry instruction is emphasized through discussion of a program written in BASIC which provides for experimenting with polynomial curves. The program listing is included. (MP)

A hungry worm is looking for something to eat according to very specific rules, and the path he takes is a graph. The problem is detailed in Applesoft BASIC using low resolution graphics for worms that turn 90 degrees and high resolution for worms that can turn 45 degrees. (MP)

A program developed by a high school freshman is presented that plots unusual graphs on the screen of a TRS-80 computer. The view promoted is that teachers of advanced mathematics should not be surprised if new ways of looking at the subject come from students interacting with computers. (MP)

Describes a series of programs written in Logo that have been used successfully to support young children's programing efforts. These programs remove the mechanical obstacles of typing, spelling, and estimating distances; remove the demands of abstract planning and ordering instruction; and provide a set of programing procedures.

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)
