In this paper, we discuss using a student model in a web-based course to sequence the curriculum. Since the teaching in a web-based course is usually non-linear, dynamic curriculum sequencing is important as there is not a linear path that will be appropriate for all students. Thus a student model needs to be constructed which can guide students through the non-linear curriculum. This student model is built on the student’s quiz performance and on how well he studies the material. The student model is used to judge how well a topic has been “learned”, which can then be used to determine which other topics are ready to be learned. In this paper, we discuss how the student model is constructed and used for curriculum sequencing.
