Towards Easier Creation of Tutorial Dialogue Systems: Integration of Authoring Environments for Tutoring and Dialogue Systems

AutoTutor is a computer program that is designed to tutor students in computer literacy or conceptual physics, by simulating the tutoring strategies used by human tutors. AutoTutor interacts with students and attempts to cover the topic material through the course of a natural conversation. During this interaction, AutoTutor uses specific dialog moves to: elicit knowledge from the student, correct student errors, and elaborate/summarize the covered material. Previous research on human tutoring has demonstrated the complex relationship between dialog moves and their effects on student learning gains. The current research with AutoTutor is aimed at examining the relationship between dialog moves and student learning as well as the program’s ability to use dialog to model the student users.
