User Model Integration in a Distributed Adaptive E-Learning System

The integration of adaptive educational systems is changing from an interesting research problem into an important practical task. One of the major challenges that need to be accepted on the way is the development of mechanisms for student model integration. In this paper we propose an approach for aligning overlay models of students’ knowledge collected by different educational tools relying on different domain representations. The approach is based on common protocols for evidence communication and manual mapping of underlying domain models. This approach has been applied for integration of two existing educational systems in the framework of undergraduate Java course.
