【摘要】：21世紀人類社會已全面步入信息化時代,人類生活的各個方面正在發(fā)生著深刻的變化,并且傳統(tǒng)的教育體系與教學(xué)模式面臨著時代變革的挑戰(zhàn),個性化學(xué)習(xí)、終身學(xué)習(xí),以及學(xué)習(xí)型社會建設(shè)已經(jīng)成為時代發(fā)展的必然需求。一種可以隨時隨地進行學(xué)習(xí)的移動學(xué)習(xí)方式是未來遠程學(xué)習(xí)的發(fā)展趨勢。作為一種新興起的移動學(xué)習(xí)方式,近年來越來越受到學(xué)習(xí)者們的歡迎,這種學(xué)習(xí)方式不僅成為學(xué)習(xí)者學(xué)習(xí)方式多樣化的補充,而且已成為現(xiàn)在遠程學(xué)習(xí)的一種主要學(xué)習(xí)方式,同樣在我國的現(xiàn)代信息化教育中發(fā)揮著越來越重要的作用。與此同時,隨著移動通信技術(shù)和計算機技術(shù)的迅速發(fā)展與融合,使得各種各樣的、便攜易用的智能移動終端設(shè)備不斷涌現(xiàn),移動網(wǎng)絡(luò)給用戶所帶來的服務(wù)和容量不斷提高�！耙苿印闭蔀槲磥砑夹g(shù)發(fā)展和社會變化的主題,“移動”與“教育”的聯(lián)結(jié)也成為教育信息化應(yīng)用的重要發(fā)展方向。目前很多高校網(wǎng)絡(luò)平臺和遠程教育機構(gòu)開發(fā)了大量的流媒體課件資源,它們主要適合在桌面計算機中使用,但不適合在移動設(shè)備終端(如PAD、智能手機等)中直接使用。如何為學(xué)習(xí)者提供適合移動終端學(xué)習(xí)的流媒體服務(wù),搭建一個方便的學(xué)習(xí)平臺,是本論文探討和解決的重點。本論文主要做了一下幾方面的工作： (1)從實際用戶的應(yīng)用需求出發(fā),分析了移動學(xué)習(xí)的國內(nèi)外研究現(xiàn)狀及未來的發(fā)展趨勢,指出了移動學(xué)習(xí)環(huán)境下的流媒體教學(xué)資源在利用過程中所存在的問題,為原型系統(tǒng)開發(fā)中的需求分析作了基礎(chǔ)準備。 (2)在系統(tǒng)開發(fā)技術(shù)方面,首先對流媒體技術(shù)的概念、特點、傳輸方式和傳輸原理等進行了詳細介紹,重點對交互式網(wǎng)頁媒體播放器FLV、開源代碼流媒體服務(wù)器Red5等進行詳細分析,同時對系統(tǒng)開發(fā)技術(shù)J2EE和Java Web進行了詳細的介紹,為后續(xù)的系統(tǒng)研究與開發(fā)打下了技術(shù)基礎(chǔ)。 (3)在系統(tǒng)功能模塊設(shè)計與系統(tǒng)的原型實現(xiàn)方面,給出了系統(tǒng)的功能設(shè)計和原型系統(tǒng)設(shè)計,該系統(tǒng)涉及的主要服務(wù)模塊有消息傳輸模塊、視頻搜索引擎模塊和視頻文件轉(zhuǎn)換格式模塊,同時給出了系統(tǒng)操作流程圖和部分數(shù)據(jù)庫的結(jié)構(gòu)設(shè)計最后給出了原型系統(tǒng)實現(xiàn)中的基本結(jié)構(gòu),并且詳細的展現(xiàn)了各個功能模塊的實現(xiàn)界面和操作流程等,基本實現(xiàn)了學(xué)習(xí)者對視頻學(xué)習(xí)資源的觀看、評論和搜索,能夠滿足移動學(xué)習(xí)環(huán)境下的基本功能需求,為學(xué)習(xí)者的移動學(xué)習(xí)帶來方便和快捷。
[Abstract]:In the 21st century, the human society has entered the information age, the various aspects of human life are undergoing profound changes, and the traditional education system and teaching mode are facing the challenge of the times change, personalized learning, lifelong learning, And the construction of learning society has become the inevitable demand of the development of the times. A mobile learning method that can learn anywhere and anytime is the development trend of distance learning in the future. As a new mobile learning method, it has been more and more popular with learners in recent years. This learning method not only complements the diversity of learning styles, but also becomes a main learning method of distance learning. Also in our country's modern information education plays a more and more important role. At the same time, with the rapid development and integration of mobile communication technology and computer technology, a variety of portable and easy-to-use intelligent mobile terminal devices are emerging. "Mobility" is becoming the theme of technology development and social change in the future, and the connection between "mobile" and "education" has become an important development direction of educational informatization application. At present, many university network platforms and distance education institutions have developed a large number of streaming media courseware resources, which are mainly suitable for use in desktop computers, but are not suitable for direct use in mobile device terminals (such as PAD, smart phones). How to provide streaming media service suitable for mobile terminal learning and how to set up a convenient learning platform is the focus of this paper. The main work of this paper is as follows: (1) based on the application requirements of actual users, this paper analyzes the current research situation and future development trend of mobile learning at home and abroad. This paper points out the problems existing in the process of using streaming media teaching resources in the mobile learning environment and makes a foundation preparation for the requirement analysis in the development of the prototype system. (2) in the aspect of system development, firstly, the concept, characteristics, transmission mode and transmission principle of streaming media technology are introduced in detail, with emphasis on FLV, an interactive web media player. The open source code streaming media server Red5 and so on are analyzed in detail, and the system development technologies J2EE and Java Web are introduced in detail, which lays a technical foundation for the subsequent research and development of the system. (3) in the aspect of system function module design and system prototype implementation, the system function design and prototype system design are given. The main service modules involved in the system are message transmission module. Video search engine module and video file conversion format module. At the same time, the operation flow chart of the system and the structure design of some database are given. Finally, the basic structure of the prototype system is given. And detailed display of the implementation of each functional module interface and operation flow, the basic realization of the learner to view, comment and search of video learning resources, can meet the basic functional needs of mobile learning environment, It is convenient and fast for learners to learn mobile.
