Konzeption und Entwicklung eines Expertenmoduls für den Bereich des logischen Entwurfs im Rahmen des intelligenten tutoriellen Systems "eTutor"

At Universities e-Leanring is used for increasing efficiency and effectiveness. Among other things it may be used to practise theoretically learned subjects. eTutor, which was implemented at the Institute for Data & Knowledge Engineering at the Johannes Kepler University, is one of these training systems. To the student eTutor offers the interactive drawing up of exercises concerning the subjects of the institute. Furthermore the instructor is supported in analyzing the solutions what will be done completely automatic in ideal case. At the moment the automatic analyze is just supported for some of the subjects of the courses. One of the not treated subjects concerns the logical database design. This Master Thesis designs an extension to the existing version of eTutor and develops a corresponding prototype. The module supports the process of creating exercises, handing in and analyzing of solutions as well as grading and giving necessary Feedback. The development of the system follows a knowledge based approach to guarantee an efficient learning. Because of this it’s necessary to collect the semantics of logical design. Within this context this means to analyze the mapping of UML-diagrams in relational structures. The resulting possibilities of mapping have to be considered in grading and in communication with the student. Following the analysis of basics, a concept to evaluate typical exercises of database design will be developed. To proof this concept a corresponding prototype will be implemented. In particular this serves to verify the concept; it won’t represent a finished tool.
