An analysis was made of the strategies by which tutors adapt their teaching to individual students; the objective was to synthesize these strategies in a computer system called SCHOLAR. Tape recordings of dialogues between tutors and students about South American geography were made to discover the strategies used by tutors. Since SCHOLAR is a well-defined program, it was possible to analyze the naturalistic data in precise terms. Individual aspects of the dialogues were analyzed separately and, based upon the analyses, several hypotheses were prepared which described how the tutor related his teaching to the individual student. These strategies were implemented in SCHOLAR, and it seems likely that the analytical method employed could be extended to a wide range of conversational situations. For example, the use of this method (Dialogue Analysis) would permit psychologists to study questions about the interactive aspects of human language processing that cannot even be considered with traditional laboratory methods.
