 內(nèi)容摘要：隨著網(wǎng)絡(luò)技術(shù)的不斷發(fā)展，我國(guó)遠(yuǎn)程教育得到了快速的發(fā)展。目前遠(yuǎn)程教育不僅僅局限于學(xué)歷教育，還包括很多方式的職業(yè)教育。同時(shí)隨著人們觀(guān)念的進(jìn)一步轉(zhuǎn)變，終生教育觀(guān)念的深入，遠(yuǎn)程教育將在未來(lái)幾十年得到更長(zhǎng)足的發(fā)展。但是就遠(yuǎn)程教育中考核學(xué)生學(xué)習(xí)情況的關(guān)鍵環(huán)節(jié)——畢業(yè)設(shè)計(jì)答辯，目前尚無(wú)針對(duì)性的解決辦法。本文分析了目前在遠(yuǎn)程教育畢業(yè)設(shè)計(jì)答辯環(huán)節(jié)存在的問(wèn)題，通過(guò)對(duì)畢業(yè)設(shè)計(jì)答辯過(guò)程的實(shí)體建模，提出了符合遠(yuǎn)程教育答辯環(huán)節(jié)的整體解決方案。并且使用Flash通信服務(wù)技術(shù)開(kāi)發(fā)了適合遠(yuǎn)程教育特征的遠(yuǎn)程答辯系統(tǒng)，旨在為遠(yuǎn)程教育畢業(yè)設(shè)計(jì)答辯提供一個(gè)功能強(qiáng)大的虛擬交互網(wǎng)絡(luò)平臺(tái)。系統(tǒng)設(shè)計(jì)了四個(gè)不同的用戶(hù)角色：學(xué)生角色、教師角色、旁觀(guān)者角色和管理員角色。不同角色具有不同的服務(wù)使用權(quán)限。系統(tǒng)支持多人同時(shí)在線(xiàn)，具有視頻交互、語(yǔ)音通信、文本聊天、電子白板、幻燈展示、評(píng)價(jià)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 eva luation and so on.
