Evaluation of Computer-Assisted Instruction in Principles of Economics

Despite increasing use, little is known about the effectiveness of web-based instructional supplements. This study assess the effectiveness of on-line materials in principles of economics courses. We have collected data on 66 students from three principles sections that describe demographic characteristics and performance and reflect the intensity of use of web-based material. We use this data to assess the effectiveness of the web-based material using a variety of empirical models. Student utilization of web-based material was significant. Both on-line computer graded practice quizzes and posting to the class bulletin board are positively correlated with student performance, but use of web-based content is not. These results suggest that faculty should focus more on developing self-test quizzes and effective bulletin board discussion projects and less on generating on-line content.
