The design of an intelligent tutoring system based on the ontology of procedural knowledge

This paper presents a new model to simulate procedural knowledge. This method divides procedural knowledge into two parts: process control and action performer. By adopting this method, we intend to help teacher construct curriculum and teaching strategies by capturing students´ problem-solving process. Using the concept of procedural knowledge in intelligent tutoring systems, we can accumulate and duplicate the knowledge of teacher/curriculum manager and student model. Teacher/curriculum manager can help the teacher create good learning maps for students. The student model can help the teacher collect students´ error types and design more appropriate teaching strategies. The implementation of our system is near completion. We will design a user-friendly interface for the system and have students play with this software to collect feedback.
