Ontology based learner-centered smart e-learning system

Rapid changes in learning contents and variability of the learners’ background can make e-learning systems inefficient due to their inflexibility in coping with such factors – changes and variability. In this paper, we are proposing an ontological approach in dealing with such issues. Our approach – the Ontology based Learner-centered Smart E-Learning System (OLSES) – allows instructors and learners semantically organize their learning objects to the learning contents repository and through the semantic searches, create filtered and ordered collection of learning objects as study plans – instructor-created study plans (ISP) and learner-created study plans (LSP) respectively. The OLSES continuously monitors the activities of the learners and updates their profiles accordingly so it can be used to search more suitable learning object for their learners.
In OLSES, the key to find relevant learning objects for the given topic is ontology-based semantic search. For that, all learning objects need to be registered in OLSES where an ontology-based meta-data definition is in place. In case of LSPs, learners can organize their own learning objects. This scheme builds the learner-centered learning environment by providing the learners with the relevant learning objects that suitably match with learners’ need so it help improve the learning performance at the same time.

Ontology of learning objects repository for pedagogical knowledge sharing

Ontology has been receiving considerable attention in the learning objects research community. This paper discusses the key concepts of ontology of learning objects repository and proposes an ontological model for pedagogical knowledge sharing. The ontological model specifies a generic organizational structure for learning objects repository based on pedagogical design categories. An ontology that actualizes such a structure allows the user of the learning objects repository to play an active role in pedagogical development through searching semantically relevant learning objects. An example of ontology for pedagogical knowledge sharing is used to illustrate the concepts of the development and use of ontologies of learning objects repository.
