The Activity Modeling Of Personal Learning Environment

This research answers the new appeal of web 2.0 of the digital times, especially rethinks the situation of e-learning environment of learner-centered, focusing upon modeling Personal Learning Environment (PLE). From the learner-centered per-spective, the participation in the various communities is discussed. This dissertation includes the following three parts, that is, clarifying the fundamental of the related theory, constructing the theoretical framework of PLE, modeling the system archi-tecture and the learning activities via ontology.First, we have discussed the fundamental of the related theory which focus upon the learning ecology, the essence of technology enhanced learning (TEL), and the modeling methodology of CSCL represented by the model of networking learning system, especially the basics of modeling the various ontologies and services of PLE.From this on, it gives out the meta-model and its metaphorical framework—learning world, which constructs the core of PLE. This meta-model concluds the six elements and four kinds of relationships, of which the three, that is subject, tool, artifact, is oriented to individuals, in the contrast the other, that is community, rule and purpose, is oriented to social mass. Moreover, it puts forward the methodology of PLE system, designing the model of its function, structure and architecture, especially the related ontologies, including of learner, learning object, learning tool, learning design and learning event.Second, it gives out the methodology of modeling learning events in PLE, which is based upon the ontological service, including the perspective of personalization, including senerio design, general service framework and corresponding atomic service and compound service. The service space is fragmented into five arenas, they are role space, media space, resource space, message space and coordinating space, on which the various learning events are represented and hence personalized services are modeled. Last, an application of PLE is put forward, that is to say, e-schoolbag, which design is discussed wholesomely.
