In this paper, the user interface design of an intelligent tutoring system is illustrated with a special focus on how to push through learn-by-doing while guiding a student through the normalization process from 1NF to 3NF. The ultimate goal of this project is to use this system as a virtual tutor to additionally facilitate a students learning of relational database schema normalization. An intelligent tutoring system is created as additional assistance to both instructors and students. This system can be adopted as in-class courseware or out-class tutoring system. In this application domain, real-life tutoring is emulated by the collaboration of five modules: student modeling, instruction modeling, session inventory, dynamic lesson planning, and user interface. The synergistic effect between a tutoring system and a student is also discussed. This study would benefit a large number of students within a confined domain of knowledge.
