Personalised Web-based learning systems

For Web-based e-learning systems personalisation, i.e. the self-adaptation of a system to the preferences and goals of the learners is a highly desirable feature. In this article we start from learner profiles to model preferences and goals. Furthermore, we refine course outlines that are first modelled by directed graphs by Kleene algebras with tests. Then we show how systems can be personalized to different learner profiles simply by reasoning with equations.
