Cognitive Tutors as Research Platforms: Extending an Established Tutoring System for Collaborative and Metacognitive Experimentation

چکیده
Cognitive tutors have been shown to increase student learning in long-term classroom studies but would become even more effective if they provided collaborative support and metacognitive tutoring. Reconceptualizing an established tutoring system as a research platform to test different collaborative and metacognitive interventions would lead to gains in learning research. In this paper, we define a component-based architecture for such a platform, drawing from previous theoretical frameworks for tutoring systems. We then describe two practical implementation challenges not typically addressed by these frameworks. We detail our efforts to extend a cognitive tutor and evaluate our progress in terms of flexibility, control, and practicality.

Automated Adaptive Support for Peer Tutoring
Collaborative activities have been shown to be beneficial, provided that students exhibit certain positive behaviors. Unfortunately, these behaviors rarely occur spontaneously. Adaptive collaborative learning support (ACLS), where an intelligent system assesses student collaboration as it occurs and provides assistance when necessary, is a promising area of research that can help scaffold stude...
متن کاملDesigning for Metacognition - Applying Cognitive Tutor Principles to the Tutoring of Help Seeking
Intelligent Tutoring Systems have been shown to be very effective in supporting learning in domains such as mathematics, physics, computer programming, etc. However, they are yet to achieve similar success in tutoring metacognition. While an increasing number of educational technology systems support productive metacognitive behavior within the scope of the system, few attempt to teach skills s...
متن کاملImproving (Meta)Cognitive Tutoring by Detecting and Responding to Uncertainty
We hypothesize that enhancing computer tutors to respond to student uncertainty over and above correctness is one method for increasing both student learning and self-monitoring abilities. We explore this hypothesis using data from an experiment with a wizarded spoken tutorial dialogue system, where tutor responses to uncertain and/or incorrect student answers were manipulated. Our results sugg...
متن کاملMutual Peer Tutoring: A Collaborative Addition to the Algebra-1 Cognitive Tutors
Although the Algebra-1 Cognitive Tutors are effective at increasing individual learning, they lack support for collaboration between students. It is likely that students would show further learning gains if they were able to use the tutors collaboratively. We intend to integrate a mutual peer tutoring script with the cognitive tutors, such that students take turns tutoring each other on problem...
متن کاملModeling Students' Metacognitive Errors in Two Intelligent Tutoring Systems
Intelligent tutoring systems help students acquire cognitive skills by tracing students’ knowledge and providing relevant feedback. However, feedback that focuses only on the cognitive level might not be optimal errors are often the result of inappropriate metacognitive decisions. We have developed two models which detect aspects of student faulty metacognitive behavior: A prescriptive rational...
