A category-based Self-improving Planning Module

Though various approaches have been used to tackle the task of instructional planning, the compelling need is for ITSs to improve their own plans dynamically. We have developed a Category-based Self-improving Planning Module (CSPM) for a tutor agent that utilizes the knowledge learned from automatically derived student categories to support efficient on-line self-improvement. We have tested and validated the learning capability of CSPM to alter its planning knowledge towards achieving effective plans for various student categories using recorded teaching scenarios.
