Regardless of whether achievement is measured in terms of single semester test,
comprehensive final exam, course average, or test performance across the semester the
iii
results presented here indicate that students perform better in traditional classes than in CAI
classes regardless of the CAI curriculum used. Moreover, despite instructional method, students
perform better on tests at earlier and later points in the semester than in the middle. Comparison
of the two CAI curricula used in this study indicated that student test performance is better for
students using Thinkwell CAI than those receiving the MyMathLab CAI curriculum. These
results have implications for math educators considering how best to use CAI to teach remedial
college algebra.
