The Effects Influenced by Mastery Learning with CAI Program for Arithmetic Assignment Statement Change for Correct Answer Rate and Necessary Time

Abstract

We developed the drill-type CAI for improving to understand the changing of variable content by the given five arithmetic assignment statements. Students learned twice on the last classes of the first and the second terms by using the CAI until they have gotten a full mark. The change of average correct answer agrees closely with the logistic curve. The changes of learning time and time to read explanation are exactly fit for the logarithmic functions. These curves are especially usefull in providing estimation of the masterly learning processes. The learning times, the cumulative initial learning time, the cumulative learning time, the explanation time, and the initial learning time of the first time on the second term decrease about a half of, a half of, one-third of, one-third of, and one-fourth of the first term, respectively.
