Competency graphs for intelligent tutoring system

Throughout the later part of the twentieth century, significant research efforts have been devoted into the area of intelligent tutoring system. While small-scale implementations of various systems have achieved successes, no system to-date has been able to achieve large-scale deployment. While the advance of networking and hypertext technologies in recent decades have seemingly introduced new hopes and promises, developments and advances in computer assisted learning have been weighted heavily on content management, organization and standardization. This paper attempts to propose a number of possible research directions related to a graph-based knowledge representation model call Conceptual Prerequisite Map that will be applicable for modeling knowledge, content, students as well as organizational knowledge needs.
