In order to show that a new type of programing for computer assisted instruction (CAI) is feasible, the SCHOLAR system was written. It is information structure oriented, based on the utilization of a symbolic information network of facts, concepts, and procedures. It can generate out of its information network the material to be presented to the student, the questions to be asked of him, and the corresponding expected answers. SCHOLAR can also utilize its information network to answer questions formulated by the student. This report gives the motivation and background for developing the program, a technical discussion of CAI programing languages in general, and curremt implementations of the SCHOLAR program. Some conclusions and recommendations for further research complete the report. A list of references and some SCHOLAR protocols are appended. (JY)
