In this brief guide, the use of microcomputer spreadsheet programs is discussed. Key characteristics are described, with examples of what these programs can do: calculations, recalculation, table lookup, data storage, logical decisions, and simple graphics. Advanced spreadsheet features are noted--consolidation, sort, and execute. Finally,…

Presents a microcomputer program (designed for Apple II but it can be modified) used to calculate various dimensions relative to a spur gear. Basic terms are identified and a program listing for gear calculations is included. (CT)

Provided is a program listing for the Apple microcomputer which helps children learn to count. From one to nine color square shapes are displayed. Displays are accompanied by sound. The player's score is revealed after 10 responses. A list of program variables is also included. (JN)

A procedure is described that enables students to perform operations on fractions with a calculator, expressing the answer as a fraction. Patterns using paper-and-pencil procedures for each operation with fractions are presented. A microcomputer software program illustrates how the answer can be found using integer values of the numerators and…

Offers examples of loss of accuracy when using digital computing devices. Discusses causes for loss of accuracy and methods of preventing loss. Presents implications that loss of accuracy has for mathematics instruction. (MDH)

Discusses computer applications to school administration tasks, in particular word processing, computations, and data base management systems. Advantages and disadvantages of program software and a chart containing an overview of application programs available are included. (JJD)

This overview of a specific spreadsheet, Microsoft's Multiplan for the Apple Macintosh microcomputer, emphasizes specific features that are important to the academic community, including the mathematical functions of algebra, trigonometry, and statistical analysis. Additional features are summarized, including data formats for both numerical and…

Describes LOTUS 1-2-3, an advanced spreadsheet with database and text manipulation functions that can be used with microcomputers by librarians to provide customized calculation and data acquisition tools. Macro commands and the menu system are discussed, and an example is given of an invoice procedure. (Author/LRW)

Describes range of options and features in gradebook programs and reviews most popular and readily available software for organizing, calculating, and updating grades: Master Grades, EA Gradebook, Gradeaid, Grader, Graphic Gradebook, Classic Plus Gradekeeping System, Records, Gradecalc, Grade Master, Report Card, Electronic Gradebook for…

Some limitations of computing with calculators and computers are described, with particular reference to typical computations which might be performed by senior secondary school students. Types of errors, the laws of number, and intermediate round-offs are each illustrated, with conclusions and implications. (MNS)

For six weeks, pupils in grades two, three, and four used either flash cards or a microcomputer program to practice basic subtraction and division facts. Equivalent learning resulted. (MNS)

The relation between mathematical and computational aspects of recursion are discussed and some examples analyzed. Definition, proof, and construction are considered, as well as their counterparts in computer languages (illustrated with Logo procedures). (MNS)

Many institutional researchers will find that the microcomputer leads to greater efficiency in everything that they do, especially in the two most critical elements of their jobs: thinking and communicating. (Author/MLW)

Using a microcomputer "dart" game, this study of 61 primary school students investigated how children of different ages used counting to make numerical estimates. Results showed developmental differences in accuracy of estimation, fluency in counting and sophistication of self-reported strategy use. (BS)

Programing a microcomputer to solve problems in whole-number arithmetic, rather than using the built-in operations of the computer, is described. Not only useful, it also enhances important mathematical concepts and is adaptable to a range of student abilities. (MNS)
