Suggestions for writing computer programs for instructional purposes are provided. Program listing for displaying a bar graph on a TRS-80 computer and listings for two subroutines (advancing frame and entering name on Apple computer) are included. (JN)

Given is an example of the solution of maximum-minimum problems by replacing differentiation techniques with microcomputers and simple BASIC programs. (MNS)

Three activities with Knuth functions are discussed and illustrated, with sample computer programs listed. (MNS)

The graphing of intricate curves and the fundamental theorem of algebra lead to a third discovery with microcomputers: Lagrange polynomials. Teaching suggestions for helping students to explore continuous change, interpolation, roots, and shifting and symmetry are presented, with a computer program listing. (MNS)

A function-graphing program is given, plus a series of experiments that students can carry out using the program. (MNS)

The material is designed to help pupils investigate how the value for slope in the equation of a line affects the inclination for the graph of an equation. A program written in BASIC designed to run on an Apple microcomputer is included. Worksheet masters for duplication are provided. (MP)

Presents a study that introduces data logging using portable computers as part of an investigative approach to science. Working with control and experimental classes of 14- and 16-year-olds, results suggest that data logging can have an impact on graphing skills at age 14 which is not necessarily repeatable at age 16. (Author/AIM)

Two different numerical methods, the bisection method and simple iteration, are discussed and illustrated by approximating the real solution of an equation, with programs for the two methods included. Alternative methods are also indicated. (MNS)

Describes how the computer algebra system Mathematica can be used to enhance the teaching of the topics of sequences and series. Examines its capabilities to find exact, approximate, and graphically generated approximate solutions to problems from these topics and to understand proofs about sequences. (MDH)

How the computer can aid the teacher in discussing plane curves is shown. Use of the zoom enables the teacher to illustrate aspects of graphs that would be difficult and time-consuming to show in other ways. Many illustrative graphs are included, and four programs are listed. (MNS)

A method of using microcomputers to teach polar coordinates and graphing is described. Two computer programs plus illustrations are included. (MNS)

Eleven experiments are presented, extending ideas for graphing functions presented in two previous articles. Computer program listings are included. (MNS)

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)

This paper outlines the development of an activity that uses the computer's unique capabilities to provide students with a meaningful and highly motivating experience with the graphing of equations. The basic design of the game calls for the computer to display a coordinate grid on which it graphs any equations that are typed in by the student.…

An intuitive approach to exponential functions is described. Microcomputers are used to aid discovery of derivatives. (MNS)
