The Cognitive Impact of a Computer Algebra System on Intermediate Algebra Students at the Community College Level.
Livingston, Tab
This study examined the cognitive impact of implementing a computer algebra system (CAS) on six intermediate algebra classes at Orange Coast College (California). The control group of three classes was taught using the traditional method of instruction and scientific calculators. The other three classes were the experimental group and were taught using the computer-based system known as CAS TI-89. The research was conducted as a quasi-experimental nonrandomized control group pretest-posttest design. The posttest results indicated no statistically significant difference in mean scores for the capability to perform mathematics by hand between the control and experimental groups. Also, analyses of chapter examinations indicated no statistically significant difference in mean scores regarding the capability to perform algebraic manipulation by hand between the control and experimental groups. However, there was a statistically significant difference in mean scores indicating that the experimental group outperformed the control group in their ability to solve higher-order reasoning skills problems by hand.
