Discusses history of the development of computer software to determine material readability and general design of readability software. Tables present summaries of: (1) parameters used by selected readability scales and their grade level applications; and (2) microcomputer software programs available, including readability techniques included in…

Faced with beginning the school year without the necessary chemicals for experiments in a newly adopted chemistry textbook, a department chairperson conceived the idea of supplementing the textbook with simulated experiments on microcomputers. The methodology used to select the appropriate software is described, with suggestions for some new…

Examples of catalog entries for microcomputer software data files are given in three sections: educational software (elementary and secondary level, college level); educational game software; business-related software. Catalog record elements, simplification methods for cataloging of machine-readable data files, and future considerations are…

Presents a problem to produce a chart in which a driver can look up the time in seconds it took to travel one mile and find out how fast the car was traveling in miles per hour. Several programs to solve the problem are listed and discussed. (JN)

A narcissistic number is a positive integer equal to the sum of its digits raised to an integral power. For example, 15 is equal to 1-cubed plus 5-cubed plus 3-cubed (a narcissistic number of order three). A computer program to find narcissistic numbers up to 10,000 is given and discussed. (JN)

Describes 10 computer programs used to draw diagrams usually drawn on chalkboards, such as addition of three vectors, vector components, range of a projectile, lissajous figures, beats, isotherms, Snell's law, waves passing through a lens, magnetic field due to Helmholtz coils, and three curves. Several programming tips are included. (JN)

This article: describes how to prevent pins on game paddles from breaking; suggests using needlepoint books for ideas to design computer graphics; lists a BASIC program to create a Christmas tree, with extension activities; suggests a LOGO Christmas activity; and describes a book on the development of microcomputers. (JN)

A questionnaire that college economics students can use to investigate the degree and nature of competition in the retail market for petrol is provided. A simple computer program is included to help in the analysis of the questionnaire. (Author/RM)

Reports observations on present use of microcomputers in elementary education in Australia, Canada, New Zealand, and the United States and presents recommendations regarding hardware, software, use of microcomputers, and teacher training. (MBR)

Describes the outstanding results obtained when a department of industrial sciences used special software on microcomputers to teach computer-aided design (CAD) as an alternative to much more expensive equipment. The systems used and prospects for the future are also considered. (JN)

How to take photographic slides of computer software for demonstration to large groups is explained in the first portion of this column. Then follow items on a Pythagorean curiosity and a computer approach to a nonroutine problem. (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)

INSTAN, a computer program designed to aid in appropriate media selection for classroom teaching, comprises three interrelated sections which focus on instructional objectives, the instructional environment, and instructional material selection. INSTAN is not described as an all-inclusive media selection model, but as a paradigm for further…

Explores use of uniquely developed microcomputer programs at Purdue University Undergraduate Library which provide reference service when reference personnel are unavailable. These programs, which allow patrons to query specific subjects of interest, also generate statistical summaries used for development of library instruction programs,…

The use of a microcomputer as the basis of a multichannel analyzer (MCA) system is described. Principles of microcomputer MCA, choice of microcomputer, input-output port, data display, MCA program, and interrupt routine (with flowchart) are the topic areas considered. (JN)
