 内容摘要：随着网络技术的不断发展，我国远程教育得到了快速的发展。目前远程教育不仅仅局限于学历教育，还包括很多方式的职业教育。同时随着人们观念的进一步转变，终生教育观念的深入，远程教育将在未来几十年得到更长足的发展。但是就远程教育中考核学生学习情况的关键环节——文档设计答辩，目前尚无针对性的解决办法。本文分析了目前在远程教育文档设计答辩环节存在的问题，通过对文档设计答辩过程的实体建模，提出了符合远程教育答辩环节的整体解决方案。并且使用Flash通信服务技术开发了适合远程教育特征的远程答辩系统，旨在为远程教育文档设计答辩提供一个功能强大的虚拟交互网络平台。系统设计了四个不同的用户角色：学生角色、教师角色、旁观者角色和管理员角色。不同角色具有不同的服务使用权限。系统支持多人同时在线，具有视频交互、语音通信、文本聊天、电子白板、幻灯展示、评价等功能。

 Abstract: With the continuous development of network technology, distance education has greatly advanced. At present, distance education is not restricted to the academic education but various vocational education as well. Meanwhile, distance education will make great progress in the future as the spread of lifelong education in our life. However, there is no key solution to the oral defense of graduation thesis which is the key link of the distance educational argument. After analyzing the problems in current distance educational argument, the author put up with a systematic solution via an entity modeling of the graduation process. What is more, in order to provide a powerful virtual network platform for educational argument, the author developed a system for distance educational argument based on the Flash Communication Services Technology. There are four different user roles designed for the system: student, teacher, spectator and manager. Different roles have different rights to use system services. Except for offering service to many users simultaneously, the system is equipped with function of video communication, voice communication, text chat, white board show, slide show evaluation and so on.
