Study of Features of Problem Group and Prediction of Understanding Level

摘要

In the previous works, we have developed Web education system using the dynamically changing three layered learning materials and estimation method of understanding level to maintain the eagerness for self learning by changing learning material based on the understanding level. In those studies, the ratio of correct answers was used directly to estimate understanding level. In this study, we developed an understanding level judging system based on the two parameter logistic function obtained from a cumulative frequency distribution and Fuzzy membership functions based on response time and number of explanation referred.
