【摘要】:如果說以計(jì)算機(jī)和互聯(lián)網(wǎng)技術(shù)為核心的第三次技術(shù)革命推動二十世紀(jì)末世界經(jīng)濟(jì)發(fā)展的話,那么從2007年開始以iPhone,Android和平板電腦等智能手持設(shè)備產(chǎn)品的井噴為標(biāo)志的移動互聯(lián)網(wǎng)的興起將再一次的重新定義各個產(chǎn)業(yè),包括教育業(yè),,從而為移動教育產(chǎn)業(yè)化提供了巨大的可能性。 本文首先對當(dāng)前國內(nèi)外的遠(yuǎn)程教育、網(wǎng)絡(luò)教育及移動教育的背景和發(fā)展現(xiàn)狀進(jìn)行多個維度的分析比較,得出依托移動互聯(lián)網(wǎng)的移動教育是改變未來教育的有效途徑的結(jié)論。然后對移動互聯(lián)網(wǎng)的前后端相關(guān)技術(shù)特性、構(gòu)架、安裝部署和訪問接口等方面進(jìn)行分析研究,對當(dāng)下最流行的三大移動操作系統(tǒng)iOS、Android、Windows Phone的平臺架構(gòu)和特點(diǎn)進(jìn)行比較分析,選定Android系統(tǒng)為客戶端的系統(tǒng)平臺。 本文描述的移動教育平臺采用客戶端/服務(wù)器架構(gòu),在平臺設(shè)計(jì)方面,本文著重研究了網(wǎng)絡(luò)框架、多屏同步、數(shù)據(jù)接口和UI開發(fā)四部分,其中網(wǎng)絡(luò)框架采用穩(wěn)定高效的Netty開源框架,利用非阻塞的NIO模型進(jìn)行網(wǎng)絡(luò)管理,根據(jù)Android平臺的特點(diǎn)提出了軌跡跟蹤與視圖同步算法及實(shí)現(xiàn),提出了一套穩(wěn)定且可拓展性強(qiáng)的消息協(xié)議規(guī)范。 在平臺的應(yīng)用層,本文實(shí)現(xiàn)了包括電子白板、文字聊天、題目導(dǎo)入與共享等多種功能。通過服務(wù)端的支撐,用戶可通過Android系統(tǒng)的手機(jī)或平板電腦登陸系統(tǒng),與好友組成群組進(jìn)行學(xué)習(xí)討論,互動交流。平臺支持單機(jī)學(xué)習(xí),多人組群討論,電子教室,支持圖像共享,多屏同步,自由繪圖,好友管理與實(shí)時狀態(tài)查看等常用功能。 經(jīng)測試證明,本文所設(shè)計(jì)移動教育平臺具有可彈性擴(kuò)展、管理靈活、交互性強(qiáng)等特點(diǎn),為移動教育產(chǎn)業(yè)提供了一種新的技術(shù)平臺,為互動教育、終身教育理念的實(shí)施提供強(qiáng)大的技術(shù)保障。平臺具備良好的可操作性和運(yùn)營價值,具有較強(qiáng)的現(xiàn)實(shí)意義和較好的發(fā)展前景。
[Abstract]:If the third technological revolution, with computer and Internet technology at the core, pushed the world economy forward at the end of the twentieth century, So the rise of the mobile Internet, marked by the blowout of smart handheld devices such as the iPhone Android and tablet computers from 2007 onwards, will once again redefine industries, including education. Thus provides the enormous possibility for the mobile education industrialization. This paper first analyzes and compares the background and development status of distance education, network education and mobile education at home and abroad, and draws the conclusion that mobile education based on mobile Internet is an effective way to change future education. Then, the related technical characteristics, architecture, installation, deployment and access interface of mobile Internet are analyzed, and the platform architecture and characteristics of the three most popular mobile operating systems, Windows Phone, are compared and analyzed. Android system is selected as the client platform. The mobile education platform described in this paper uses client / server architecture. In terms of platform design, this paper focuses on four parts: network framework, multi-screen synchronization, data interface and UI development. The network framework adopts a stable and efficient Netty open source framework and uses the non-blocking NIO model to manage the network. According to the characteristics of the Android platform, the algorithm and implementation of trajectory tracking and view synchronization are proposed. A stable and extensible message protocol specification is proposed. In the application layer of the platform, this paper realizes many functions, such as electronic whiteboard, text chat, topic import and sharing, etc. Through the support of the server, users can access the system through the mobile phone or tablet computer of the Android system, study and discuss with the group of friends, and interact with each other. The platform supports single-machine learning, multi-person group discussion, electronic classroom, image sharing, multi-screen synchronization, free drawing, friend management, real-time status view and other common functions. It has been proved by test that the mobile education platform designed in this paper has the characteristics of flexibility, flexible management and strong interaction, which provides a new technology platform for the mobile education industry, and provides a new technology platform for interactive education. The implementation of the concept of lifelong education provides a strong technical guarantee. The platform has good maneuverability and operation value, and has strong practical significance and good development prospect.
