The use of computer algebra software in teaching intermediate and college algebra
Two groups of students in an intermediate algebra course as well as two groups of students in acollege algebracourse were compared with respect tothe use/non-use of computer algebra software in the courses. In both courses, the students using the software outperformed the students not using the software on a common final exam. For the intermediate algebracourse, the experimental group (the one using the software) had a mean equal to 80.8, the control group had a mean equal to 76.1, and the p-value was 0.13. For the college algebra course, the experimental group had amean equal to 75.1, the control group had amean equal to 69.4, and the p-value was 0.22. Furthermore, the experimental groups expressed very positive feelings about the use of the software in the course. In addition, the instructors in the experimental groups received their best student evaluations ever when teaching algebra courses.
