Since the topic of appropriate use of calculators is often discussed here, I thought I would share an experience I had today with one of my students.
She is studying for her test (tonight) and included in the material are formulas like the distance formula, midpoint formula, quadratic formula, and others. She said her high school teacher showed her how to program those formulas into her calculator (programmable calculators are allowed but not required in my class), but she said it was better for her if she worked the problems out on paper and used the calculator just to make sure she got the right answer. She asked me if that was a good idea. I almost hugged her. Isn't this what we want? The calculator is a wonderful thing. It first helps her learn the formula, then allows her to believe in the formula and trust what she has learned. This student, I believe, understands appropriate use of technology much better than most students and also many instructors.
