SQL-Tutor is the first constraint-based tutor. The initial conference papers about the system were published in 1998 (Mitrovic , , ), with an IJAIED paper published in 1999 (Mitrovic and Ohlsson, International Journal Artificial Intelligence in Education, 10(3-4), 238-256, ). We published another IJAIED paper in 2003, focussed on the Web-enabled version of the same system (Mitrovic, Artificial Intelligence in Education, 13(2-4), 173-197, ). In this paper, we discuss the reasons for developing the system, our experiences with the early versions, and also provide a history of later projects involving SQL-Tutor. [ABSTRACT FROM AUTHOR] |
