The design of instructional materials, especially Intelligent Tutoring Systems, is difficult, often because of student differences. Both the time students take to complete such tutorials, and their resulting scores, are dependent upon the length and difficulty level of the material, as well as the expertise of the student. This paper presents a first attempt to utilize the simulation of the student to help in the design of an Intelligent Tutoring System using an object-oriented approach. Simulated students respond to simulated tutorials through simulated interfaces. The object-oriented approach provides an easily adaptable framework for using the results, both in time and student scores, to aid the educator in making difficult design decisions. Statistics from successful simulation runs are presented, along with plans for future study.
