Design of a delegable SCORM conformant learning management system

Owing to the emergence and flourishing of the Internet, traditional teaching and educational activities are increasingly relying on the convenient and global-reaching networking technology. To boost up the development of e-learning technology and the interoperability of learning materials, the Advanced Distributed Learning Initiative defined a data-sharing standard, called the Sharable Content Object Reference Model (SCORM). In SCORM, because all learning materials (either SCOs or assets) are sharable, users cannot share (or delegate) parts or all of their teaching materials at will. This paper proposed an access control and delegation model for SCORM conformant learning management systems. Also, a prototype was developed to demonstrate the feasibility of the proposed model.
