The Reduced Reparameterized Unified Model (Reduced RUM) is a diagnostic classification model for educational assessment that has received considerable attention among psychometricians. However, the computational options for researchers and practitioners who wish to use the Reduced RUM in their work, but do not feel comfortable writing their own…

Survey sampling is fundamentally an applied field. The goal in this book is to put an array of tools at the fingertips of practitioners by explaining approaches long used by survey statisticians, illustrating how existing software can be used to solve survey problems, and developing some specialized software where needed. This book serves at least…

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)

The article reviews eight math software programs, rating each on ease of use, visual appeal, reliability, documentation, educational value, error handling, and value for money. A narrative section further describes each program. (CL)

This article illustrates that mathematical theory can be incorporated into the process to solve differential equations by a computer algebra system, muMATH. After an introduction to functions of muMATH, several short programs for enhancing the capabilities of the system are discussed. Listed are six references. (YP)

Described is a computer algebra system that can be used to help students understand the calculus. Provides several examples of solving calculus problems using muMATH. Lists eight references. (YP)

Evaluates 25 software packages (consisting of more than 40 individual programs), all aimed at one or another facet of mathematics learning. Title, source, current price, and detailed review (indicating the educational quality of the package) are included for each entry. (JN)

A program for drawing a line segment is developed. (MNS)

An efficient division algorithm is developed, using a computer program, to convert any positive fraction to its decimal representation. The computer program listing is included. (MNS)

The section includes four articles on the use of computers for gifted students. Topics covered include basic information for parents, care and operating routines, a curriculum guide for computer literacy, the computer's role in problem solving, and computer applications for mathematically gifted students. (CL)

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)

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

Computer lessons have become an integral part of many 1985 mathematics textbooks. Various issues related to the emphasis of computer lessons in these books are discussed. A comparative analysis (in chart format) of 10 textbooks is included. Type of lessons, supplementary computer material, and correlated software are among the areas considered.…

Reviews CATUSPLOT, a mathematics utility aimed at high school algebra through college-level calculus. Basic program capabilities include plotting, tabulating, integrating, and locating of intersections of functions composed of combinations of polynomial, trigonometric, and exponential functions. Rated excellent on all areas examined…

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)
