Furthermore, with the refinement of peer-to-peer communication, the emerging network models will allow thousands of learners to access these solutions, regardless of their different computer systems. These solutions can be compared to storage devices that share learning resources according to the users needs. With the substantial increase of information nodes and the multiplicity of computers making use of this complex network, cognitive overload or trans-actional distance inherent to the technology can quickly become an obstacle to the learning process. Therefore, the Grid requires the development of appropriate learning tools and services. This paper presents an approach to reduce cognitive overload and transactional distance for a virtual learning community (VLC) on the Grid. This paper proposes a computer-Grid communication device called "Grid-e-Card." Its goal is to bring users together according to their signature to share collective intelligence in a social context: the knowledge they have acquired, the objectives they wish to meet, or the learning services that correspond to their needs. This methodology is based on a set of P2P-agents who handle users electronic portfolios (e-Portfolios) as knowledge prosthesis and exploit e-Learning qualification (e-Qualification) processes as aggregation methods to dynamically organize people in relevant virtual learning communities. << 收起
