The purpose of this study was to determine the effect of the TI-81 Graphics Calculator as an instructional tool on college algebra students' conceptual and procedural achievements involving functions and graphs and on the students' attitudes toward mathematics. The study was a posttest-only, equivalent control group design conducted with students…

Presents an overview and discussion of some results of research on the use of graphing calculators organized into the following categories: (1) achievement studies, (2) conceptual understanding, (3) problem solving, (4) classroom dynamics, and (5) future research needed. (29 references) (MKR)

Research has often found little or no significant differences in overall performance for math students using graphing calculators compared to traditional (non-calculator) classes. However, when performance is divided into procedural and conceptual levels, significant differences appear at the conceptual level. This study investigates the relation…
