Characteristics of computer arithmetic that may cause programing problems are considered. How numbers are stored in a computer, round-off error, overflow, and double-precision arithmetic are among the topics considered. (FL)

This article demonstrates an iterative method of evaluating the cosine function which can be derived using secondary school trigonometry. A sample computer run is included. (MM)

The history of computer use in education as a problem solving tool is briefly traced; suggestions are made for teacher training in the computer sciences. (DT)

A unit on the quadratic equation is described. The discovery approach is used and the computer is integrated into the study of mathematics. (MK)

Issues about computer use are addressed by a discussion activity designed to help students think about situations and understand various points of view. Four situations are given, each presented from the viewpoints of four persons. (MNS)

Computer Literacy Objectives developed by the Minnesota Educational Computing Consortium (MECC) computer literacy study are given. The objectives are grouped under the six headings: Hardware; Programing and Algorithms; Software and Data Processing; Applications; Impact; and Attitudes, Values, and Motivation. (MK)

How computer methods can be applied to an old problem and how computer efficiency affects the solution to that problem are illustrated. (MK)
