Abstract

Intelligent tutoring systems to become more available to support a learner's instructional needs, it is necessary to remove impediments to the interoperability of independently produced systems. Tutoring systems are active instructional components and two significant requirements are necessary to achieve interoperability. The first is a standard means of instruction-related identification and control among these active components. The second is a standard means of exchanging beliefs about a learner's mastery of the domain objectives.

This paper focuses on the second of these requirements: that information related to learner mastery should not remain captive within systems as private data that is generally unusable by other learner sensitive systems. Systems must share, in a meaningful way, the mastery and other beliefs about an individual learner. Specifically this paper examines this requirement from both a learning system and a learner model perspective and provides a proposal for sharing mastery information among independently developed learner sensitive systems.

Before tutoring systems can become ubiquitous, an individual must be treated as the same individual by independently produced learner sensitive systems.

Biography

Stephen Pacheco has worked in the software development field since 1972. Most of his early efforts were related to real-time systems, modeling and simulation. The last 15 years have been mainly involved in development of computer-based training systems, both real-time and non-real-time. His focus for the last 7 years has been intelligent tutoring systems.
