Graphing calculators have been used in the mathematics classroom for speed, to leap hurdles, to make connections among representations, and to permit realism through the use of authentic data. In this study, a graphing calculator tutorial provided on the Casio FX1.0 and FX2.0 PLUS models was found to serve a fifth purpose, improving manipulative skills. Specifically, after using the tutorial, students in a beginning college algebra course scored significantly higher on a test on solving linear equations. Results concerning a change in attitudes were tentative, although they suggest that the tutorial also may contribute to improved attitudes.
