(2004) DB-suite: experiences with three intelligent, web-based database tutors. Journal of Interactive Learning Research, 15(4), pp. 409-432.1093-023Xhttp://hdl.handle.net/10092/309E-learning is becoming more and more popular with the widespread use of computers and the Internet in educational institutions. Current e-learning courses are nearly always developed using course management systems (CMS), such as WebCT or Blackboard. Although CMS tools provide support for some administrative tasks and enable instructors to provide online instructional material, they offer no deep support for learning: students have access to on-line material, simple multi-choice quizzes and chat tools, but there is no ability to track student’s progress and adapt the learning material and instructional session to the individual student. In this paper we present our experiences with three Web-based intelligent tutoring systems in the area of databases. SQL-Tutor teaches the SQL query language, NORMIT is a data normalization tutor, and KERMIT teaches conceptual database modelling using the Entity-Relationship data model. All three tutors in DB-suite have been used and evaluated in the context of genuine teaching activities. We present the most important features of these systems, as well as evaluation results. The DB-suite tutors have proved to be very effective in supporting deep learning, and are well liked by students.enweb-based intelligent tutoring systemsJournal ArticleFields of Research::330000 Education::330100 Education Studies::330107 Educational technology and mediaFields of Research::280000 Information, Computing and Communication Sciences::280200 Artificial Intelligence and Signal and Image Processing
