Expert system for tutoring intelligence analysts. Master's thesis
Intelligent Computer Aided Instruction (ICAI) allows a computer to perform some of the functions normally performed by a human instructor. This thesis describes the design and implementation of an ICAI system which presents radar principles to a student, tests him, finds out why he made an error, and then corrects the error. To allow the system to be used for different subject domains, the knowledge required to teach was kept separate from the knowledge about the subject domain. During the design phase, the knowledge about teaching was partitioned into eight knowledge bases, the functions of these knowledge bases were described, and their interactions with one another were shown. During the implementation phase, each knowledge base was developed separately before being integrated into the system. Of these eight knowledge bases, the knowledge base that tests the student received the major emphasis. This knowledge base generates a multiple-choice question, finds the answer, and creates plausible incorrect answers to serve as distractors. Although the radar range equation was used to test this knowledge base, this knowledge base performs the same functions with any equation which is entered into the system in its canonical form. Although this thesis establishes the framework for an ICAI system and then demonstrates its feasibility, further research is required before the system can be used in an actual training environment.
