Computer-Assisted Instruction and Student Performance in Macroeconomic Principles

Steven Cox reports on a research project in which computer-assisted instruction was tried at Arizona State University. He explains the experimental design which involved a comparison of student learning of macroeconomic principles by CAI with that of a control group. Fairly detailed accounts are given of the computer simulations Cox used. The statistical significance of nine student characteristics in terms of their impact on overall test performance is discussed. This article should have practical value to others doing research in this field.
