Distance Education Courseware Resources, Share Research

Based on network technology,distance learning has the advantages such as learning anytime anywhere,sharing learning resource with open system and easy cooperation. During the development of distance learning,people realize that the share and reuse of learning resource artery important. By the use of network technology,we can achieve the share of learning resource in a low level,but we still have not got a specification which can allow learning resource share in the courseware and instruction level. So if we want to achieve the share of learning resource in the most extent. First,we should establish a courseware resource description framework to describe and organize the courseware resource;second,we should use a common and easy content packing specification to pack the courseware content;last,we should establish a run-time environment to realize the courseware framework and content packing. From the analysis above,we raise the solution project of achieving the share of courseware resource based on SCORM specification.Distance learning specification can support the share of learning resource and the interoperability of system;this article introduces the important distance learning specification in the world,and gives our analysis. After introducing XML and comparing it to HTML,we point out XML is the proper carrier of learning resource. Then we raise the thought of achieving courseware resource share based on SCORM specification. This article sets forth it from three aspects:SCORM metadata,which helps us to locate and manage learning resource effectively;SCORM content aggregation model,which helps us to describe and pack learning content based on content packing specification;SCORM run-time environment,which includes the launch of the learning content,the communication between learning resource and LMS,the communication data model. We also analyze and compare the communication model based on HACP protocol and API. And in the last,this article raises a courseware development and management system model based on XML and SCORM,to test and verify the thought of courseware content packing and share,we also analyze the realization of the model.
