Architecture for BPEL based requirement driven learning management

With support of multiple learners and multiple roles in a learning activity, IMS Learning Design (LD) specification provides a collaborative scenario for participants. However, IMS LD provides insufficient support for interaction among learning activities and can not dynamically integrate learning resources to meet the continually changing service requirement. In this paper, we propose a BPEL-enhanced requirement driven learning management architecture to address the issues of personalize adaptive learning. Our approach models the learning activity by combining IMS LD with BPEL and matches optimal learning sequence base on CBR (case-based reasoning) method. By providing expandable learning sequences flexibly, it satisfies the different actual demands for personalize learning.
