In spring 1996, Arizona's Glendale Community College (GCC) undertook an evaluation of a microeconomics course using the national Test of Understanding in College Economics (TUCE III). Specifically, the study sought to determine how GCC student outcomes compared to national results on the TUCE III and if the microeconomics course made a statistical difference on student scores between the pre-course and post-course tests. The TUCE III pre-test was administered to students in two sections of the microeconomic course during the first week of class, while the post-test was administered as a final exam. Study results, based on outcomes for 30 students who took both the pre- and post-tests, included the following: (1) the mean pre-test score for GCC students was 10.70, significantly below the national norm of 12.35; (2) the mean score on the post-test for GCC students was 16.10, indicating that the course did make a significant difference in student TUCE III scores; (3) GCC students' mean post-test score was also not significantly different from the national mean of 16.67; and (4) although the TUCE III was found to provide valuable data, it was recommended that it not be used on a regular basis at GCC due to issues related to grading, the underrepresentation of community colleges in the national sample, and other issues. The test instrument, national pre- and post-test results, tables of score comparisons, and an examiners manual are appended. (TGI)
