The purposes of this study were to apply mathematics software, DERIVE, to design teaching activities for vocational school students, and to explore its effect on students’ learning of inequalities. The one-group quasi-experimental pretest-posttest design was used to examine the experimental effects. Participates were 86 first graders from two classes in a private vocational high school in Hsinchu city. After the experimental activities, the S-shape strategy was used and students were separated into two group based on their pretest grades. Group A took their posttest in the computer lab and Group B took their posttest in the ordinary classroom. The research results are as following: 1. No matter where students took their posttest, students’ test scores on the posttest was significance better than those on the pretest. 2. Based on analyzing students’ performance on each question of the posttest, it was found that Group A students displayed their ability to apply DERIVE to solve solutions of an inequality. Therefore, Group A students did perform better on those test questions that were related to find the solutions of an inequality. It seemed that students in both groups were still lack of a connection between graphic and algebraic meaning of an inequality. And no significance difference was found in the two groups on these test questions. Based on research results and findings, suggestions were provided for future reference.
