An application of functions and their inverses is described--the coding and decoding of messages, or cryptographs. The helpfulness of computers is noted, with two programs listed. (MNS)

Presented are two problems that can be solved using a computer simulation by students who have completed Algebra II. The distance and bisector formulas and the various forms of the equations of a circle and straight line are the topics. Computer program listings are included. (MNS)

Described is the Alfa Project in Uruguay, designed to integrate computer education into secondary schools through teacher-training. Both teacher-users and teacher-authors were considered. Course objectives, curriculum content, and teaching guidelines are presented. (MNS)

Numerical inaccuracies, which occur in many ordinary computations, can create serious problems and render answers meaningless. Cancellation and accumulation errors are described, and suggestions for experimentation are discussed. (MNS)

A computer program that can be easily modified to offer individualized drill, practice, or remediation is presented. How the program operates is described, and how to modify it for numerical order, number sequences, number words, inequalities, basic operations, percents, decimals, fractions, and measurement is noted. (MNS)

The process of designing a microcomputer program to cumulate and record student grades at Brigham Young University is outlined. The development was undertaken by the registrar's office with the input of faculty, including those who had previously designed their own grading software. (MSE)

Describes file management package offering relatively sophisticated features: conversion of previously downloaded records from commercial database into local file; keyword searching on inverted keyword file; full-text searching on author, title, bibliographic source, abstract; sorting by author, title, bibliographic source, publication year;…

Stressed is a conceptual approach to absolute value, based on the visualization of the graphs of absolute-value equations. An important by-product is predicting a graph on the basis of certain constraints. Four worksheets plus teacher comments are included. (MNS)

Suggests that students can learn the physics of a musical note by learning how to synthesize sounds on a computer. Discusses ADSR (attack, decay, sustain, and release of a note) and includes a program (with listing) which students can use to examine ADSR on a Commodore 64 microcomputer. (JN)

The principle of the multiplier-accelerator interaction is explained, and how a computer program to model it can be developed is shown. A series of simulations that can be used to explore the model's behavior are suggested. The simulations can be used in college-level economics classes. (Author/RM)

This article presents a computer program for aiding prediction of how to make maximum use of the physical plant to accommodate the instructional program at a secondary school. It uses Conrad's formula for determining capacity, room needs, and utilization of facilities. The formula, BASIC program, and a sample table are provided. (DCS)

Discusses the progress of computer integration in the United States' educational system. Computer-oriented programs and courses, instructional and software considerations, rationale for using microcomputers in classrooms, computer uses in specific subject areas, and problems are examined. An annotated list of federally funded computer-oriented…

Presents a set of classroom activities and a computer program that have been used to help students intuitively grasp, in a minimum of instructional time, such fundamental concepts as hypothesis testing, random sampling, statistical inference and p-values. The lesson shows students how statistical thinking and microcomputers can be used in…

Suggested is the presentation of problems for which student teams are to write computer programs which will reveal the results of guesses at the answer by users of the program. Illustrative problems and programs are included. (MNS)

Offers suggestions for designing and writing educationally effective computer lessons, outlining the instructional applications of computers. Also presents directives on lesson preparation, program format, graphics use, screen design and question schemata. Problem solving and integrative aspects of computerized instruction are stressed.
