Generalizing the design of a computer tutor using delimited explanations

A computer tutor is defined to be any combination of artificial intelligence and multimedia for instructional purposes. It uses forms, arrays, databases, and other constructs in its effective realization. The main problem in the construction of such tutors is threefold. The first is mastering the subject to be taught so that an effective tutoring system can be laid out. The second is mastering the authoring tool so that an effective presentation can be produced. The third is mastering the techniques of artificial intelligence so that navigation within the presentation becomes more natural and so that the overall task of producing a tutor can be randomized, thus minimizing the overall burden on the designer. There are two ways of doing this, not mutually exclusive. The first is through generalized schematic templates and the second is through delimited responses to user requests for assistance
