Effective support for Meta-cognition in Intelligent Tutoring Systems Several of my (present and past) projects focus on supporting metacognition, the ways in which learners think about and regulate their own learning processes. Previous research has shown that ITSs (e.g., Cognitive Tutors) can be very effective in improving domain-level competence (e.g., skill in math). If they could be applied equally successfully at the metacognitive level, they might foster even greater learning gains, or better yet, greater ability on the part of learners to learn in new domains. My research showed that an intelligent tutor can support self-explanation (a metacognitive strategy) in a way that leads to better learning at the domain level. The next, and more ambitious, step is to show that intelligent tutors can help students acquire better metacognitive abilities, so that they become better learners. My colleagues and I have made progress toward this goal, focusing on help seeking as a second important area of metacognition, but are still working on fully cracking open this tough nut. |
