Learning and authoring on the basis of an adaptive system

This paper describes ways of improving methods and techniques used in the area of computer-based learning. In particular, an adaptive system is described, and ideas about how to apply it to the field of computer-assisted instruction. The system provides a model which contains information about the user's knowledge. On the one hand, the intention is to make the information about the student's abilities obvious to an instructor who will be able to support the student by individual instructions and learning facilities according to the student's knowledge. On the other hand, the system's adaptability will be used to support the instructor himself in designing learning sequences with respect to his/her pedagogic and didactic aims
