The paper describes the design and development of NORMIT, an intelligent tutoring system (ITS) that teaches database normalization to university students. NORMIT is a Web-enabled system, and we discuss its architecture and techniques used to deal with multiple students. We also discuss constraint-based modeling (CBM), the underlying student and domain modelling approach. NORMIT is the first in the series of constraint-based tutors developed at ICTG that teaches a procedural task, and we comment on the suitability of CBM for such tasks. We also discuss the plans for the evaluation of the system and future work.
