Presented is a simulation program for Apple II computer which assays the effects of a series of variables on bacterial growth and interactions between microbial populations. Results of evaluation of the program with students are summarized. (CW)

This book and three accompanying floppy disks introduce HyperCard 2.1 for the Macintosh microcomputer and its programming component, HyperTalk, to educators. The first four chapters introduce the basics of HyperCard, including its structure, which is based on a hierarchy of units; the use of tools and graphics; and ways of linking information…

This book seeks to develop, enhance, and expand students' understanding of mathematics by using technology. Topics covered include the advantages of spreadsheets along with the opportunity to explore the 'what if?' type of questions encountered in the problem-solving process, enhancing the user's insight into the development and use of algorithms,…

This book reviews over 250 computer programs oriented toward the three- to six-year age range. Each program has been screened with checklists designed to rate such factors as ease of use, content strength, instructional design, and developmental appropriateness. The opening section contains an alphabetical list of all the software titles covered,…

A computer program that simulates the random evolution of a metabolic pathway is given. The program shows that natural selection preserves favorable traits if they occur in a specific sequence. (KR)

Presented is the change-point estimation which is a variation on point estimation for a two-sample problem. This variation relies on the elementary properties of the expected value and variance operators, is intuitive and is easily accessible for introductory statistics courses. Data for this exercise may be produced by a BASIC program which is…

Designed by educator-led development teams who view the computer as an enabling technology that encourages children to become active learners, this CD-ROM disk is intended for students in kindergarten through grade 6. The disk enables students to create interactive stories fueled by the power of their imaginations and create adventures set in an…

Describes laboratory-oriented software programs that are short, time-saving, eliminate computational errors, and not found in public domain courseware. Program availability for IBM and Apple microcomputers is included. (RT)

Uses chaos theory to investigate the nonlinear phenomenon of population growth fluctuation. Illustrates the use of computers and computer programs to make calculations in a nonlinear difference equation system. (MDH)

Discussed are the use of probability simulations in a mathematics classroom. Computer simulations using regular dice and special dice are described. Sample programs used to generate 100 rolls of a pair of dice in BASIC and Logo languages are provided. (YP)

Discussed are solutions to the problem "What is the expected number of rolls for the total first to exceed 6?" Several algebraic solutions are presented. A computer program which may be used to simulate this problem is included. (CW)

Predicting weather conditions is a topic of interest for students who want to make plans for outside activities. This paper discusses the development of an inexpensive computer-interfaced classroom weather station using an Apple IIe computer that provides the viewer with up to the minute digital readings of inside and outside temperature,…

Described are several programs that enable the user to evaluate derivatives to order n of any elementary function by using the combination of automatic differentiation method and A Programming Language (APL). Programs calculating first- and higher-order derivatives are presented. Selected APL symbols are appended. (YP)

Presents an example of a proof to the mathematical problem of the sum of the cubes of the digits. Provides a Pascal program to search for these results. (MVL)

Presents experiments to measure the velocity of sound through metals and other amorphous materials. Describes the equipment used to make the measurements and the possibility of interfacing with a microcomputer. (MDH)
