*Mathematica*is a self-contained environment where you can do all the things you need to do. The students author. They can write. They can calculate. They can draw graphics. They can do it all in one environment."

## Overview

"It's all about teaching the concepts." That's Debra Woods' philosophy, and she says *Mathematica* is key in helping her achieve this goal. She teaches *Mathematica*-based courses at the University of Illinois and through its online math program, NetMath.

Woods says *Mathematica*'s visualization capabilities make all the difference in the way her students explore and grasp lessons. "What we can do in *Mathematica* we simply can't do with calculators or textbooks," says Woods. "In *Mathematica*, you can not only visualize things, but you can also manipulate them to see how they would change. And you can have those graphics, along with calculations and text, all in one environment."
