In Phase I we have developed a prototype Intelligent Training System (ITS). The design of the prototype is domain independent; the area of instruction is orbital dynamics. In Phase II we intend to expand the prototype into an its that will teach a complete introductory course in orbital dynamics. The its will adapt to the learning style of the student, coach the student during problem solving, and analyze the student's errors. The system will be validated by means of student testing. In addition, we plan to develop an instructor interface that will enable an instructor, who is not a programmer, to insert instructional material into the its. We will test the effectiveness of this interface and the domain independence of the its design through the development of a second its, which will instruct in calculus. The Phase II effort will result in three products, two itss and the instructor interface, each of which will have significant military and commercial value.
