Rimac: A Natural-Language Dialogue System that Engages Students in Deep Reasoning Dialogues about Physics
Katz, Sandra; Jordan, Pamela; Litman, Diane
Society for Research on Educational Effectiveness
The natural-language tutorial dialogue system that the authors are developing will allow them to focus on the nature of interactivity during tutoring as a malleable factor. Specifically, it will serve as a research platform for studies that manipulate the frequency and types of verbal alignment processes that take place during tutoring, such as abstraction and specification, and thereby enable us to test their prediction that the benefits of "interactivity" hinge on the nature, frequency, and appropriateness of its occurrence. The purpose of this poster is to introduce the Rimac project and system to the education research community. Since this study is in an early stage, the authors do not yet have findings and conclusions to report. The proposed poster will describe the project goals, illustrate Rimac with sample reflective dialogues, and describe the "decision rules" guiding automated abstraction and specification of student input that we derive from human tutorial dialogues, and teachers' feedback on the system. (Contains 2 figures.)
