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)

An environment for investigating vector-valued functions in two- and three-dimensional space using Logo is described. The language is presented, followed by use of the environment. Appended are Logo primitives and procedures. (MNS)

Two topics are discussed that can be presented in a discussion of the annual percentage rate (APR): difference equations and fixed-point iteration. A program in BASIC using the iteration procedure is included. (MNS)

Discusses the use of Logo tools, spinners, dice, and coins for creating and understanding probability. Gives procedures for devising a spinner board and other necessary functions for performing the activity. Presents ideas for extending the experiment. (RT)

The question of whether to teach computer programming to elementary and secondary students has been widely debated. This study examines the relationship between computer programming experience, mathematics experience, and general variable skill. The sample consisted of 46 students (aged 9 to 17) at a summer computer camp. The programming level was…

Reports on diagnostic testing of eighth grade students' performance using two different methods. Concludes that the computer version was significantly more difficult than the other. Suggests that students may perform mathematics differently due to the characteristics of the mediums used. (RT)

Provides a brief description, rationale for selection, and recommendations for use of: "The Geometric Supposer"; "Graphing Equations"; "Electronic Spreadsheet"; "LOGO"; "muMATH"; "The King's Rule"; "Algebra Series"; and "Golf Classic." Lists contents, costs, and…

Describes three games that one can play with or without a computer involving arithmetic, strategy, and problem solving techniques. Lists an abbreviated program for BASIC. Provides information on availability of the variable number game and the ARITHMETICULATOR which does calculations of large numbers and runs on IBM PCs. (RT)

A real-life problem involving a greenskeeper needing to know the area of golf greens is presented, with solutions using a scale drawing, Maple's methods, and Heron's formula. Methods are checked with a computer and discussed mathematically. Three computer program listings are included. (MNS)

Abundant and deficient positive integers are investigated, with a computer program listed. (MNS)

Two computer programs are given to provide simulations, for any value of n, to keep count of the frequency of the first significant digit. (MNS)

Presented are reviews of several microcomputer software programs. Included are reviews of: (1) Microstat (Zenith); (2) MathCAD (MathSoft); (3) Discrete Mathematics (True Basic); (4) CALCULUS (True Basic); (5) Linear-Kit (John Wiley); and (6) Geometry Sensei (Broderbund). (RH)

Presents a method for using matrix algebra and computers to encode and decode secret messages. Provides examples of coding procedures, a short review of matrix multiplication, and a BASIC program for use with secret messages containing up to 1000 numbers. (RT)

Brief articles on producing videotapes of the execution of a program on a microcomputer, an illustration of the sums of numbers and squares, and the distance from a point to a line are included. (MNS)

This book, second in a series dealing with scientific programing in the BASIC language, provides students, engineers, and scientists with a documented library of subroutines for scientific applications. Subjects of the eight chapters include: (1) least-squares approximation of functions and smoothing of data; (2) approximating functions by series…
