Supporting Learner Model Exchange in Educational Web Systems

Abstract

The heterogeneity of learner models in structure, syntax and semantics makes sharing them a significant challenge for existing educational web systems. Creating mappings between the different types of learner models is one technique that is used when attempting to overcome these issues. This paper presents an overview of research currently being conducted in the area of learner model exchange and defines a categorization, derived from existing educational web systems, of the different mapping types that are required for learner model mapping. Following this, a framework is presented that supports the creation and validation of these different mapping types and the exchange of learner information between multiple heterogeneous educational web systems.
