Knowledge management mechanism and system supporting overall e-learning lifecycle process

As the relationship between knowledge management and e-learning becomes closer and closer and the rapid development of the technology related with Computer Supported Collaborative Learning (CSCL), an appropriate kind of knowledge management mechanism supporting overall e-learning lifecycle process is needed to improve the effectiveness and efficiency of e-learning. Therefore, an SADT-based e-learning process architecture and an SOA-based knowledge management mechanism are proposed respectively. After that, we discuss the process management model of e-learning from an overall lifecycle perspective. At last, the corresponding knowledge management architecture is presented to further support this process management.
