Abstract:

The main purpose of the research was to show that a new type of computer-assisted instruction CAI, in many respects more powerful than existing ones, is feasible, and to demonstrate by example some of its major capabilities. In order to do that, a set of computer programs, the SCHOLAR system, was written. Both the conception and the implementation of this system are discussed in detail. Actual on-line protocols of the usage of SCHOLAR are included. The present approach to CAI can be defined as being information-structure-oriented ISO because it is based on the utilization of a symbolic information network of facts, concepts, and procedures. SCHOLAR is capable to generate out of its information network the material to be presented to the student, the questions to be asked to him, and the corresponding expected answers. SCHOLAR can also utilize its information network to answer questions formulated by the student. As a consequence, SCHOLAR is capable of maintaining a mixed-initiative dialogue with the student. This dialogue takes place in a subset of English. Author
