Artificial Intelligence in Education, 13(2).http://hdl.handle.net/10092/307The paper presents SQLT-Web, a Web-enabled intelligent tutoring system for the SQL database language. SQLT-Web is a Web-enabled version of an earlier, standalone ITS. In this paper we describe how the components of the standalone system were reused to develop the Web-enabled system. The system observes students’ actions and adapts to their knowledge and learning abilities. We describe the system's architecture in comparison to the architectures of other existing Web-enabled tutors. All tutoring functions are performed on the server side, and we explain how SQLT-Web deals with multiple students. The system has been open to outside users sinceMarch 2000. SQLT-Web has been evaluated in the context of genuine teaching activities. We present the results of three evaluation studies with the University of Canterbury students taking database courses, which show that SQLT-Web is an effective system. The students have enjoyed the system’s adaptability and found it a valuable asset to their learning.enWeb-based ITSArchitectures for adaptive and intelligent Web-based educational systemsIntelligent problem solving support via the WebStudent modeling and student model servers in the WebEmpirical studies of Web-based adaptive and intelligent educational systemsJournal ArticleFields of Research::330000 Education::330100 Education Studies::330107 Educational technology and media
