A Preliminary Study of a General Model for Supporting Tutorial Dialogues

摘要

One of the critical factors contributing to the effectiveness of human tutoring isthe conversational aspect of the instruction. We present a project with the goal of developinga general model for supporting tutorial dialogues that could be used in both well- andill-defined instructional tasks. We have previously studied how human tutors provideadditional support to students learning with an existing intelligent tutoring system. On thebasis of these findings we developed a model for supporting tutorial dialogues, which wepresent in this paper. We used this model in a Wizard-of-Oz study to provide adaptivesupport. The results show that students did learn the relevant domain knowledge and thathuman tutors mostly agreed with the interventions generated from the model.
