Many Intelligent Tutoring Systems (ITS) support adaptive navigation according to the prerequisite relationship between the learning materials. This research aims to propose a method so that a system can verify and update the prerequisite relationship. We assume that the prerequisite can improve the learning result or is necessary for the study of the learning object. Prerequisite relationship can be verified by means of the conditional dependence of the passing rate in a learning object with that of its prior learning object. As a result, new learning paths can be formed adaptively to suit for different groups of learners.
