Seamster, Thomas L., Eike, David R. and Ames, Troy J. (1990): Knowledge Acquisition and Representation for the Systems Test and Operations Language (STOL) Intelligent Tutoring System (ITS). In: D., Woods, and E., Roth, (eds.) Proceedings of the Human Factors Society 34th Annual Meeting 1990, Santa Monica, USA. pp. 1323-1327.

This presentation concentrates on knowledge acquisition and its application to the development of an expert module and a user interface for an Intelligent Tutoring System (ITS). The Systems Test and Operations Language (STOL) ITS is being developed to assist NASA control center personnel in learning a command and control language as it is used in mission operations rooms. The objective of the tutor is to impart knowledge and skills that will permit the trainee to solve command and control problems in the same way that the STOL expert solves those problems. The STOL ITS will achieve this objective by representing the solution space in such a way that the trainee can visualize the intermediate steps, and by having the expert module production rules parallel the STOL expert's knowledge structures. This approach has resulted in a knowledge acquisition process that places a great emphasis on both the domain expert's knowledge structures and solutions steps. Concept sorting tasks combined with scaling analysis techniques are being used for organizing and analyzing domain concepts. These techniques have been used to identify the critical STOL commands, the related concepts, and significant problems that will direct the design of the tutor's user interface as well as the production rules of the expert module.
