An Intelligent Tutoring System (ITS) is a computer system that is used to tutor students in some domain of study. It is different from other educational systems as it uses knowledge to guide the teaching strategies. ITS tries to optimize the student‘s mastery of domain knowledge by controlling the introduction of new problems, concepts and instruction/feedback. The focal point of the teaching process is student model which lets know what the student knows about a particular domain.

Constraint Based Modeling is a new idea proposed by Ohsollon, focuses on learning from errors. The constraint based model says everything is allowed until it does not violate the constraint. Whereas, Student Based Model says about what the student know or what they believe to know. Here we are combining these two approaches. Any particular domain is based on some basic principles, if the student knowledge satisfies those principles (constraints), the Tutoring System is successful.

The SQL - Tutor is an existing ITS that uses a constraint-based model. In SQL-Tutor constraints are LISP code fragments, where domain structural knowledge is incorporated into the constraints via ad hoc functions which is as loose as Ohsollon description.

I am trying to give a more specific representation of constraints in the form of user defined functions. This approach has two advantages:

i. Constraints are easier to author
ii. They can be used to generate solution on demand.

This approach seems to improve learning performance in the classroom. The authoring tool helps to develop a quick and efficient system.
