            The purpose of this study was to investigate the effect of the use

            of the Voyage 200 graphing calculator, a portable computer algebra

            system (CAS), on the achievement of junior college students in

            mathematics. Positive results were obtained though the gain was not

            statistically significant.


            Using the CAS Attitude Scale (CASAS), which comprises four

            sub-scales, developed by the researcher, students'' attitudes

            towards CAS were also examined and statistically significant results

            were found. The reliability index, Cronbach’s alpha, for each of the

            four subscales of the CASAS was found to be high and the reliability

            for total scale was 0.96. The four sub-scales of the CASAS were also

            found to be highly correlated with each other and with the total
