The Effects of Using the TI92+ Calculator as a Demonstration Device in Geometry Instructions.
Din, Feng S.; Whitson, James M.
This study investigated the effects of using the TI-92+ calculator to demonstrate geometric diagrams to students in class. The participants (N=83) were from three 10th grade classes. A pretest, treatment, posttest with control group design was used in the study. The treatments lasted for 12 weeks. Results from data analyses via the Dependent t-test and the ANCOVA test indicated that for the within-class comparisons, all classes made significant gains in their geometry learning, and no significant differences were found from the between-class comparisons, which indicates that the TI-92+ calculator can be used as an effective demonstration device in geometry instructions.
