摘要
远程教育是适合远程传输和交互学习的现代化教育新模式。远程教育系统的核心是媒体素材、网络课件等教学资源的建设。如何对原始的教学资源进行格式转换,使受教育者能够方便地利用各种浏览器进行访问及交互,成为远程教育系统设计的关键。MVC模型为开发交互式应用系统提供了一个优秀的设计模式,XML是一种强大的描述语言,在研究两者技术的基础上,设计了在MVC模型中引入XML的适合多媒体数据转换的新型软件框架,并将它应用在远程教育系统的建设中。新框架有效地增强了远程教育系统的易用性和可维护性,并使之具备了移动教学功能。
Distance education is a new education mode that fits remote transformation and interactive learning. The core of a distance education system is the construction of teaching resources, including multimedia material and internet courseware. The transform ation of the original education resources,which enables educatees to visit resources and learn interactively through various browsers, has become the key of distance education system construction, MVC pattern is an excellent framework for interactive systems design. XML is a powerful data description language. Based on the research on the above two techniques, a new framework for multimedia data transformation is proposed. XML is applied to MVC pattern. The application of the framework in distance education system shows that the new framework greatly improves the facility and maintainability of the system, and it also provides the distance education system with mobile education function.
