| Modern E-Learning is a new educational mode brought by the development of information technology. At current, there are abundant E-learning resources, but they are monotone and isolated. What's more, the resources have low reusability and lack a navigation system to supply personalized service to each user. These problems have hampered the popularization of E-learning in China heavily.To resolve the problems mentioned above, the thesis proposed a multimedia synchronizing scheme on the base of streaming media technology and ASF model, realized combination and synchronization of different materials. Courseware made according to this scheme could synchronize various materials with teachers'teaching video, thus simulated a living teaching environment.To achieve sharing and interoperability of resources, effective description and organization of courseware are needed, which could be realized by"standardization". The thesis introduced the main standards and criterions in E-learning, analyzed Chinese Educational Technology Standardization (CELTS) and Extensible Markup Language (XML) thoroughly, applied XML banding strategy to band the courseware with CELTS-3 LOM( Learning Object Metadata) and CELTS-9 CP(Content Package) , achieved standardization of courseware resources.A courseware is to serve learning, as to the problem of personalized navigation in the course of students'learning, the thesis constituted a structured knowledge model, analyzed the current students learning status and their interests, lead each student to the related knowledge collection according to the knowledge model and the analyzed result. Then the system could orientate the students to the needed course zones by marking. Thus, the students could complete all the learning tasks step by step in this system.The proposed E-learning solving scheme is realized by .NET technology. It has been applied and runs well. |
