Illustrates the ease with which programs occupying only a single command line of a graphics calculator can be constructed. (MKR)

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…

Uses a graphing calculator to demonstrate that dividing by a fraction is the same as multiplying by the reciprocal. Students graph a division problem and an equivalent problem, multiplying by the reciprocal. They find that the graphs are the same. (SKS)

Explores some ideas for the imaginative use of a graphics calculator in introductory statistics teaching. (Author/ASK)

Explores the effects of varying the coefficients in the general quadratic function using graphing calculators. (MKR)

Presents examples in which the graphing calculator can provide students with particularly valuable insights into some major statistics ideas such as random numbers. (ASK)

Discusses the appropriateness of lower secondary school students using graphics calculators instead of scientific calculators. (ASK)

Focuses on solutions to a single problem using both induction and deduction by utilizing a TI-82 graphing calculator to illustrate symbolic, numerical, and graphical approaches to the problem. (ASK)

Discusses various ways to explore graphs on the TI-82 graphing calculator by using the three different cursors: the free-moving, trace, and result cursors. (MKR)

Analysis of the constraints and potential of the artefact are necessary in order to point out the mathematical knowledge involved in using calculators. Analyzes and categorizes observations of students using graphic and symbolic calculators into profiles, illustrating the transformation of the calculator into an efficient mathematical instrument.…

Students have difficulty associating equations of vertical and horizontal lines with their respective graphs. Presents an activity using a TI-82 graphing calculator to eliminate this confusion and to strengthen students' understanding. (ASK)

Uses the average-monthly-temperature function as an application of the sine wave. Argues that the attractive aspect of gas bill graphs is that they clearly illustrate that sinusoidal curves are useful and meaningful in an everyday context. (ASK)

This booklet contains a representative sample of the efforts of colleagues at 11 institutions to use graphing calculators to enhance the teaching of calculus and precalculus. The first section contains examples of graphs for teachers to choose from for presentations, including: simple examples to illustrate some standard ideas in precalculus,…

Illustrates exploration of composition of functions, translations, and inverse functions on a graphing calculator. Includes reproducible student worksheets. (MKR)

Attempts to answer and generalize the question: When is the numerical derivative obtained on the graphing calculator greater than the actual derivative, and when is it smaller? Discusses symmetric difference. (MKR)
