Graphing calculator use is often thought of in terms of pre-calculus or continuous topics in mathematics. This paper contains examples and activities that demonstrate useful, interesting, and easy ways to use a graphing calculator with discrete topics. Examples are given for each of the following topics: functions, mathematical induction and…

Drawing from experiences at Ohio State University (OSU) with remedial college students and with 12th grade students without elementary algebra skills, this paper outlines a numerical approach to algebra instruction using handheld calculators. Introductory material discusses problems with traditional approaches to math education and outlines some…

Provides a rationale for using calculators to study large numbers in the elementary school. Suggests that calculators be used to encourage children to develop their interest in large numbers, to become more adventurous in their explorations of them, and to stimulate their curiosity in their occurrence.

Provides a simple routine which allows first-year physics students to use programmable calculators to solve otherwise complex electrostatic problems. These problems involve finding electrostatic potential and electric field on the axis of a uniformly charged ring. Modest programing skills are required of students. (DH)

Elementary school mathematics curricula are being developed that are designed to use calculators. As the calculator-integrated curricula are developed, tests must be developed that involve the use of calculators. Some examples of how achievement tests using calculators would be different are considered. (RH)

Demonstrates the use of the memory functions on hand-held calculators by presenting three activities that are appropriate for use in middle grades (4-8). The constant arithmetic feature of the calculator is also required. (JN)

Described is the calculator's place in the classroom and its potential for reshaping our computationally oriented curriculum. Activities are suggested for ways calculators can effectively be used to develop four types of mathematical thought. (Author/DS)

Discusses numerical methods to compute approximate solutions of a differential equation. Provides a Pascal program for the extended Euler-Heun method. (YP)

Shows a direct solution for factoring trinomials, without trial and error, using a calculator. When a calculator is not available, the mathematical chore is eased somewhat using reference tables, as shown in two noncalculator methods (determining nonfactorability and factorability). (JN)

Addresses issues related to the use of microcomputers for solving problems. Includes considerations of the impact of software availability, the nature of software for chemical education, general-purpose software, and dedicated software. (JN)

Provided is an activity designed to give grades 7-12 students opportunities to discover numerical patterns and to derive general conclusions from observing data. The activity focuses attention on patterns in products such as 33x34, 333x334, and 3333x3334. Three worksheets and answers are included. (JN)

An exploration of a problem called solving quadratic congruences modulo p is detailed and is built around an alternate method of deriving the quadratic formula. Three practical pedagogical values that have been experienced by students and instructor when the material was presented to classes are noted. (MP)

The College Entrance Examination Board has not permitted calculator use on the Scholastic Aptitude Test because of unresolved concerns about equity, implications for test content, and logistical and security issues. Those issues no longer seem insurmountable, and significant changes are being introduced on many tests. (MSE)

Focuses mainly on a common example in technology-rich mathematics curricula, namely the line of best fit, followed by a discussion of two additional examples, interpolating polynomials and complete graphs. (ASK)

Describes a process which allows students to explore repeating decimals without being inhibited by the limitations of the calculator display. In addition, the process can take some of the mystery from the decimal forms of rational numbers. (JN)
