【摘要】：隨著計算機Web技術(shù)的不斷發(fā)展，互聯(lián)網(wǎng)環(huán)境的不斷改善。通過網(wǎng)絡(luò)實現(xiàn)遠(yuǎn)程教育已經(jīng)不是問題。國內(nèi)許多知名院校都有遠(yuǎn)程教育機構(gòu)，利用計算機網(wǎng)絡(luò)高效率的完成教學(xué)事務(wù)的日常處理已成為現(xiàn)實。但是，傳統(tǒng)的遠(yuǎn)程教育模式并不能滿足現(xiàn)階段人們快速學(xué)習(xí)的要求，而且傳統(tǒng)的遠(yuǎn)程教育只是對學(xué)習(xí)資源的積累，在教學(xué)互動方面并沒有行之有效的方法。慕課平臺的出現(xiàn)有效的解決了傳統(tǒng)遠(yuǎn)程教育的弊端。 本文通過對慕課平臺的需求和技術(shù)可行性分析決定使用B/S架構(gòu)，主要使用了JavaEE技術(shù)、Flex技術(shù)、Red5視頻服務(wù)器技術(shù)以及WebService等技術(shù)設(shè)計并實現(xiàn)了一個可以提供在線學(xué)習(xí)與教學(xué)互動的學(xué)習(xí)平臺。 首先，對于慕課平臺的特點進行了分析，慕課平臺是一個大規(guī)模的網(wǎng)絡(luò)開放教學(xué)平臺，針對平臺的特點決定平臺要解決的主要問題是設(shè)計一個開放的教學(xué)平臺，能夠?qū)崿F(xiàn)大量的學(xué)生同時在線學(xué)習(xí)，能夠提供不同課程的發(fā)布與管理，對于大量的學(xué)生能夠保證教學(xué)視頻正常的播放，根據(jù)課程中設(shè)置的課程練習(xí)題可以判斷學(xué)生的答案并且統(tǒng)計出分?jǐn)?shù)。對于課程的相關(guān)資料可以按照課程的分類進行專項的管理。根據(jù)平臺要解決的問題利用B/S架構(gòu)實現(xiàn)大量學(xué)生同時在線學(xué)習(xí)，利用Flex和Red5視頻服務(wù)器技術(shù)保證在大量并發(fā)的前提下教學(xué)視頻的正常播放，利用SSH2技術(shù)保證了課程數(shù)據(jù)的獨立性，實現(xiàn)了多門課程的發(fā)布與管理。對于在線測試的練習(xí)題可以根據(jù)學(xué)生的答題記錄進行各個分?jǐn)?shù)段人數(shù)的統(tǒng)計，，并且利用Flex技術(shù)中的圖表組件實現(xiàn)統(tǒng)計信息的圖形化顯示。對于課程相關(guān)資源利用Struts2技術(shù)和WebServic技術(shù)實現(xiàn)了課程資源根據(jù)課程不同分類進行統(tǒng)一管理。 本文給出了平臺模塊主要算法的設(shè)計以及實現(xiàn)過程，并以文字描述的方式闡述了相關(guān)調(diào)用過程。在測試章節(jié)闡述了整個平臺的部署環(huán)境和最終測試結(jié)果，通過對測試結(jié)果的分析證明了慕課平臺達(dá)到了功能需求和性能需求。最后，對本課題在開發(fā)過程中的工作成果進行了總結(jié)，并且提出了關(guān)于慕課平臺進一步的改進方向。
[Abstract]:With the continuous development of computer Web technology, the Internet environment has been improved. Distance education through the network is no longer a problem. Many well-known colleges and universities in China have distance education institutions, and it has become a reality to use computer network to complete the daily processing of teaching affairs efficiently. However, the traditional distance education model can not meet the requirements of rapid learning at this stage, and the traditional distance education is only the accumulation of learning resources, and there is no effective method in teaching interaction. The emergence of the platform has effectively solved the disadvantages of traditional distance education. In this paper, we decide to use the B / S architecture based on the analysis of the requirements and technical feasibility of the platform. This paper mainly uses JavaEE technology, Red5 video server technology and WebService technology to design and implement a learning platform which can provide online learning and teaching interaction. First of all, the characteristics of the platform are analyzed. The platform is a large-scale open network teaching platform. The main problem of the platform is to design an open teaching platform according to the characteristics of the platform. Can realize a large number of students to learn online at the same time, can provide different courses of release and management, for a large number of students can ensure the normal play of teaching video, Students' answers can be judged and scores counted according to the course exercises set in the course. The relevant information of the course can be managed according to the classification of the course. According to the problems to be solved by the platform, using the B / S architecture to achieve a large number of students at the same time online learning, using Flex and Red5 video server technology to ensure the normal playback of teaching video under the premise of a large number of concurrent. The independence of course data is guaranteed by using SSH2 technology, and the release and management of many courses are realized. The number of students' scores can be counted according to the record of students' answer questions, and the graph component of Flex technology can be used to realize the graphical display of statistical information. Struts2 and WebServic are used to realize the unified management of curriculum resources according to different classification of courses. In this paper, the design and implementation of the main algorithms of the platform module are given, and the related calling processes are described in the form of text description. In the test chapter, the deployment environment and the final test results of the whole platform are described. The analysis of the test results proves that the Mutue platform meets the functional and performance requirements. Finally, the paper summarizes the work of this subject in the course of development, and puts forward the direction of further improvement of the platform.
