In this thesis we have developed an algorithm to evaluate each student's level of understanding and find out which subjects they are not good at when they get on-line lectures at a cyber university. This algorithm is based on fuzzy logic using each student's scores adjusted according to the level of difficulty. In addition, we also introduced a "duplex intellectual lecturing system" and an "evaluation method based on the level of understanding." With the duplex intellectual lecturing system students can ask questions on line at a cyber university and under the new evaluation method, there is no need for students to move between classes. As a result of a computer simulation test, the duplex on-line lecturing system has proven to be more effective than the current one-way cyber lecturing system.
