Competence Based Adaptive E–Learning in Dynamic Domains

This paper describes a competence–based approach to adaptive e–learning based on knowledge space theory and its competence–performance extension. Assigning to each learning object sets of required and taught competencies, one can easily build a course adapting in each step to the learner’s current knowledge state. The competence assignments implicitly define a prerequisite structure on the set of competencies. At the same time, a decentralised storage of these assignments allows (i) for easy changes of learning objects and courses in dynamically changing domains and (ii) for reuse of adaptive material in different courses by implementing the competence assignments through slightly extended metadata standards. An example implementation will be briefly presented.
