Use of a semantic learning repository to facilitate the creation of modern e-learning systems

Abstract:

Learning Object Repositories (LOR) has been usually implemented as traditional document stores. In this paper we explain the design of a Semantic Learning Repository that expand the concept of LORs to include linked information of entities not usually referred as Learning Objects, but necessary for the implementation of more advance e-learning systems. To demonstrate the the usefulness of this new concept, this paper presents the design and evaluation of a Personalized Learning Path Recommender based on the Semantic Learning Repository. The main result obtained from the evaluation is that the inclusion of external information enables more accurate recommendations and these recommendations has a measurable impact on the student learning.
