Biarritz, France: 6th International Conference on Intelligent Tutoring Systems ITS 2002, 2-7 Jun 2002. Lecture Notes in Computer Science, 2363, 377-387.978-3-540-43750-5http://hdl.handle.net/10092/317KERMIT is an intelligent tutoring system that teaches conceptual database design using the Entity-Relationship data model. Database design is an open-ended task: although there is an outcome defined in abstract terms, there is no procedure to use to find that outcome. So far, constraint based modelling has been used in a tutor that teaches a database language (SQL-Tutor) and a system that teaches punctuation and capitalisation rules (CAPIT). Both systems have proved to be extremely effective in evaluations performed in real classrooms. In this paper, we present experiences in using CBM in an open-ended domain. We describe system’s architecture and functionality. KERMIT has also been evaluated in the context of genuine teaching activities. We present the results of an evaluation study with students taking a database course, which show that KERMIT is an effective system. The students enjoyed the system’s adaptability and found it a valuable asset to their learning.enConference Contributions - PublishedFields of Research::330000 Education::330100 Education Studies::330107 Educational technology and mediaFields of Research::280000 Information, Computing and Communication Sciences::280100 Information Systems::280104 Computer-human interactionFields of Research::280000 Information, Computing and Communication Sciences::280100 Information Systems::280111 Conceptual modelling
