Lists and explains a computer program written in BASIC which calculates teacher salaries using a salary index. Modification of this payroll program is suggested as a student project in schools which teach computer programing. (JJD)

Discusses how computational errors arise in analysis of data and how they can be minimized. Shows that all computations are subject to roundoff/truncation errors and how such errors are propagated and influence the stability and condition of a reaction. Applications to procedures used in analytical chemistry are addressed. (JN)

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)

Because calculators and computers obviate the need to teach certain mathematical skills that machines handle more efficiently, suggests eliminating paper/pencil computation from classrooms and introducing new, relevant topics and activities. Several of these topics/activities are discussed. (JN)

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)

Some insights are provided into techniques for removing the mystery of how calculators evaluate functions. (Author/MK)

Described is the use of an interactive terminal-oriented computing system that has access to files of thermodynamics data. (Author/SA)

The rule of 78 is used by banks and loan companies to compute the amounts due when installment loans are paid early. Describes an unexpected case of negative amortization when the rule is applied. Presents an actual problem and discusses the case. (YP)

Described is a project in which microcomputers were used by seven teachers in grades 2-6 in Edmonton, Alberta. The microcomputer was placed in each classroom for one-half day every day for a full school year. Teachers were asked to use it at least 70% of the time for practice in mathematics with individual students, using the Milliken Math…

The first aim in school might be to help children become more aware of the algorithmic processes they use; then, ensure that they can devise algorithms and define them. Many examples of how these aims can be met are given, including the use of calculators and computers. (MNS)

A framework is presented for integrating use of a microcomputer into a statistics unit. Descriptions of some programs suitable for the Apple microcomputer and ideas for lessons are included. (MNS)

Discusses: (1) advantages of a computer lab; (2) types of computer programs that can help students develop computational, application, comprehension, and analytical skills; (3) how computers can help students with such affective goals as appreciation and motivation toward mathematics; and (4) content areas where computers can be useful. (JN)

To answer students' questions about predicting grade averages or projecting grades needed to attain specific grade goals, academic advisors can use computerized grade calculations. Spreadsheet and HyperCard versions of grade calculation software are discussed and illustrated, and suggestions are offered for using them in specific advising…

Described are the use of spreadsheet programs in chemical engineering calculations using Lotus 1-2-3 macros. Discusses the macro commands, subroutine operations, and solution of partial differential equation. Provides examples of the subroutine programs and spreadsheet solution. (YP)

Presents an algorithm to estimate pi by approximating a unit circle with a sequence of inscribed regular polygons. Demonstrates the application of the algorithm with a hand-held calculator and an Apple computer. Provides a program to calculate pi in Pascal programing language. (12 references) (MDH)
