Abstract:

Knowledge space theory provides a formal model for representing students' knowledge and describing the structure of a domain of knowledge. A similar formal structure can be used to described the structure of hypertexts. The combination of knowledge space theory and the formal hypertext model leads to a framework for intelligent tutoring systems which provides individualized learning paths to a student. Using powerful procedures from relational database systems and from knowledge space theory, we get e.g. an efficient selection of appropriate teaching documents.
