In this paper we describe how to simulate the behavior of a human tutor when the student cannot answer a question in a dialogue-based tutoring system. This paper describes an implementation of our analysis of human tutoring behavior using the simple plan-based framework of our tutoring system CIRCSIM-Tutor v. 2. By carefully choosing the retry strategies according to our categorization of the student’s answer, our machine tutor can simulate some sophisticated human tutoring behaviors, such as hinting and grain of truth responses.
