ABSTRACT
The thesis of this chapter is that cognitive simulation modeling is a way to obtain specifications of the knowledge required to do a task, or to evaluate the adequacy of proposed specifications of the body of knowledge. Such specifications should be detailed and precise enough that test questions based on them would allow assessment of the exact knowledge required to perform a skill, and training materials based on them would be made complete, compact, and efficient. Such precision specifications could assist in the development of higher quality, traditional paper-based testing and training systems, and the actual representations of the knowledge contained in a simulation could be the input for intelligent tutoring and other computer-based advanced training and testing systems.
