Dynamic Exploration of Algebra Using the TI-92 Graphing Calculator

Abstract

One of the more interesting features of the TI-92 graphing calculator is the animation feature. Using this feature allows students the opportunity to explore, experiment, and visualize mathematics as a dynamic process. By animating a mathematical object, such as a rectangular box, wave signal, or a surface in three-dimensional space, students are provided with an opportunity to break away from static representations of these objects. Students no longer need rely strictly upon their ability to visualize changing quantities or parameters. The animation feature allows them to predict and to test these predictions based upon actual observations. This presentation will explore activities that assist students in experiencing mathematical concepts in this dynamic mode.
