The Design of Decomposed Scorm Structure With Embedded LCMS Broker

This study proposed a decomposed SCORM (Sharable Course Object Reference Model) structure with embedded LCMS Broker that provides the integration of learning resources and balance of network traffic. The system consists of the Learning Management System (LMS) for processing basic data, learning data and learning records of learners, and the Learning Content Management Systems (LCMSs) for managing and storing course resources. The Web Service cross-platform distribution configuration of this study provides common communications between systems and enhances the capability of integrating learning resources. The proposed embedded LCMS Broker ensures a load-balancing functionality for LCMS of different domains. The connection program embedded into the PC of the learner via LMS connects to the embedded LCMS Broker for access to required teaching materials from each LCMS. The LCMS with the minimum load is then selected from suitable LCMS as the source of the teaching materials. Since the SCORM standard integrates teaching materials and platforms using JAVA Script, cross-domain scripting issues may occur when the learning system and course resources are stored in subsystems of two different domains. This study proposed a SCORM learning environment by creating a cross-domain server with URLrewrite technology to provide a solution for this issue.
