Abstracts for Session 2
Friday, 10:15am

2A. Martha Haehl, Maple Woods Community College, Kansas City, MO, Computer Mediated Algebra and Reform Mathematics - an Oxymoron or a Real Possibility?
The speaker, an author of the Interactive Math multimedia project by Prentice Hall, will speak about her experience teaching with Interactive Math in Introductory Algebra and Intermediate Algebra. She is taking a reform approach around a predominantly traditional project. She will discuss her concern that computer mediated algebra projects, which have been designed predominantly to teach pencil and paper procedures, may ironically ignore the impact that technology should have on mathematics curriculum. She will outline how she has used Interactive Math to free up class time, traditionally spent teaching procedures, to incorporate real-life problems and discovery activities. Her students have to become familiar with the software and tools for Interactive Math, use E-mail, search information on the Internet, and use a word processor. The audience does not need any particular technical expertise; however, familiarity with the Internet and computer mediated algebra systems is helpful.

2B. Daniel Willis, Loras College, Dubuque, IA, Extrapolation Methods in Numerical Analysis on the TI-86
Numerical methods play a central role in the "reform" approach to Calculus teaching and learning. Most Calculus textbooks include some discussion of numerical methods for differentiation, integration, and the solution of differential equations. "Extrapolation" is a standard "trick" that can be used with almost any numerical method to speed up the convergence of the method. The speaker will give an overview of the theory and application of extrapolation methods on the TI-86 (applicable to any graphing calculator). He will survey the most commonly used numerical methods in Calculus, including numerical differentiation, Riemann sums, Trapezoidal Rule, Midpoint Rule, Simpson's Rule, and Euler's method (for DE's).

2C. Julane Crabtree, Johnson County Community College, Overland Park, KS, Learning Styles, Intelligences, and the Technological Mathematics Classroom
This interactive session will focus on using learning styles, Multiple Intelligence Theory and technology in all levels of mathematics. Participants will experience several learning style inventories and will determine ways that these can be incorporated into mathematics. Sample lessons, diskettes and ideas for quick and easy implementation will be provided.

2D. Andy Bennett, Kansas State University, Manhattan, KS, Web-based Mathematics Teaching
This talk will cover the speaker's experiences teaching a course in "Web-Based Mathematics Teaching" during the spring intersession, May/June 1999. The course focused on how to create active web pages where the students did more than just read static text. Topics in the course included creating and using java applets, chat rooms, threaded E-mail systems, forms for student feedback, and online quizzes.

2E. William Frank & Mark Adams, Barstow School, Kansas City, MO, Computer Applications in Precalculus from Dollars to Dial Tones
This session will demonstrate two specific applications that can be used in a Precalculus course. The concept of exponential functions is expanded to model an annuity. Excel is used to construct a "dynamic" loan payment schedule. The second application uses a shareware program, Goldwave, and will use trig functions to model sound. Specific sounds will be modeled, including the touch-tone telephone.
