Graphing calculators are sophisticated devices that can run small computer programs and draw the graph represented by complex equations in an instant. In the last few years, they have become mandatory in many high school mathematics classes and can be used on the SAT and advanced placement exams and other standardized tests. This article sets forth the arguments for and against the use of these handheld computers in the classroom and during assessment. (author/sw)
