This paper describes an approach to model students knowledge growth from novice to expert within the framework of a help system, ABSYNT, in the domain of functional programming. The help system has expert knowledge about a large solution space. On the other hand, in order to provide learner-centered help there is a model of the students ́actual state of domain knowledge. The model is continuously updated based on the learner ́s actions. It distinguishes between newly acquired and improved knowledge. Newly acquired knowledge is represented by augmenting the model with rules from the expert knowledge base. Knowledge improvement is represented by rule composition. In this way, the knowledge contained in the model is partially ordered from general rules to more specific schemas for solution fragments to specific cases (= example solutions). The model is implemented but not yet actually used for help generation within the help system. This paper focuses on knowledge diagnosis as accomplished by the model, and on an empirical analysis of some of its predictions.
