The Goal Structure of a Socratic Tutor. Technical Report No. 3.
Stevens, Albert L.; Collins, Allan
This report describes the current version of the Why System, a script-based Socratic tutor which uses tutoring strategies formulated as production rules. The current system is capable of carrying on a dialogue about the factors influencing rainfall by presenting different cases to the student, asking for predictions, probing for relevant factors, entrapping the student when he has not identified all necessary factors, and presenting counterexamples. This system is incomplete because it lacks a goal structure to guide the tutorial sessions. The report outlines a more complete theory of the goal structure of Socratic tutors based on analysis of human tutorial dialogues. The main goals are to refine the student's causal model and predictive abilities. Sub-goals include the diagnosis of deficiencies in the student's knowledge and the correction of these deficiencies.
