I have created a comprehensive TI-89 Program that covers the entire Calculus AB and BC curriculum following the Graphical, Numerical & Algebraic approach. It has turned out to be a great help for me getting a better insight into Calculus. Also, it allowed me to visually demonstrate Calculus concepts such as Area Approximation or 1 dim. Motion. Surely, my students love it as they can use it to learn for themselves and to quickly check answers.
To view a detailed list of the program's capabilities visit www.nilshahnfeld.com .
I claim that adequate usage of the Graphing Calculators with CAS capabilities in the class room will a) allow more effective, GNA based teaching. b) change even further the character of the calculator based questions on the AP exam.
