Cycle-Talk - A Tutorial Dialogue System that Supports Negotiation in a Design Context Cycle-Talk is a collaborative project to integrate a set of tutorial dialog tools developed by Carolyn Rose with the Cognitive Tutors and CTAT. Building upon the CyclePad simulation environment developed at Northwestern University, one of the major research goals of the CycleTalk project has been to investigate the instructional effectiveness of novel ways of using tutorial dialogue technology in an exploratory learning enviornment. In our recent work, we have empirically evaluated the effectiveness of a tutorial-dialogue based approach to guided exploratory learning involving problem solving goals that are negotiated between tutor and student rather than dictated by the tutor or freely chosen by the student. This approach, which we refer to as Negotiable Problem Solving Goals (NPSG), is located on a previously untested space on what we call The Exploratory Learning Continuum. Our empirical results from a classroom evaluation provide strong evidence in favor of tutorial dialogue support in exploratory learning environments. (Project summary by Carolyn Rose) |
