TAILIEUCHUNG - Context Aware Ubiquitous Learning Environments for Peer-to-Peer Collaborative Learning

When additional resources are required, additional nodes and instances can easily be added to the cluster with no downtime. Once a new instance has been started, applications using services can immediately take advantage of it with no changes to the application or application server. Oracle Real Application Clusters is an extension to the Oracle Database and therefore benefits from the manageability, reliability, and security features built into the Oracle Database. | Yang S. J.

Ubiquitous learning is characterized by providing intuitive ways for identifying right learning collaborators right learning contents and right learning services in the right place at the right time. Our context aware ubiquitous learning environment consists of three systems namely peer-to-peer content access and adaptation system personalized annotation management system and multimedia real-time group discussion system. Since the effectiveness and efficiency of ubiquitous learning heavily relies on learners surrounding context in this paper we will address a context model and context acquisition mechanism for collecting contextual information at run time. We have built a context aware ubiquitous learning environment and in this paper we will address how this newly designed environment can fully support the needs of peer-to-peer collaborative learning. Keywords Ubiquitous learning Context aware Peer-to-peer Collaborative learning Introduction Various learning systems have been developed in the past decade the majority of these systems are implemented either with client-server architecture or are centralized server based. The client-server and centralized server approaches are metaphors of student-teacher and repository centric which reflect real world learning scenarios
