Integrating Engineering into TI-83 Math Education Course

Abstract

North Carolina A&T State University is a recipient of a National Science Foundation Planning Grant for “Bridges for Engineering Education”. As a part of the initiative, the Engineering and Education faculty are working together to enhance the exposure to engineering concepts for pre- service and in-service teachers. The first course identified for this effort was Technology and Applications in Secondary School Mathematics, a graduate course primarily taken by in-service teachers with a desire to enhance their students understanding of the materials through hands on activities with the TI-83 calculator.

The paper illustrates how engineering concepts have been integrated into a graphing calculator course and sparked new interest and collaborations between engineering and education faculty as well as the math teachers in Guilford County. The partnership has great potential for exposing several middle and high school students to the practices of the engineering profession.

Introduction

In the Fall of 2001, North Carolina A&T State University established an Academy of Teaching and Learning to enhance the learning process for all students on campus and to provide students with the foundation to become more effective instructors. Key teachers from each of the units through out the campus were charged with this task and met on a regular basis to develop programs and activities for the entire campus. One of the notable growths out of this effort was a partnership between an Engineering and a Math Education faculty member. Through this partnership and the creative effort that both faculty members brought, the idea was borne for a class that would increase the awareness of engineering concepts and how best to incorporate them into high school math classes through the use of the TI-83 calculator. The TI-83 calculator was selected because it is the dominant calculator used in Guilford County’s algebra courses.

Overview

The course developed was offered as a graduate level Math Course. It is designed to discuss the techniques of teaching Pre-Algebra, Algebra, Geometry, Pre-Calculus, Calculus and other secondary mathematics using calculators, calculator based labs and other technology. Primary focus was placed on the TI-83 calculator and the TI-92 hand held computer and how best to integrate its functions into the Middle School Algebra curriculum. Specific objectives were:
