【摘要】：21世纪人类社会已全面步入信息化时代,人类生活的各个方面正在发生着深刻的变化,并且传统的教育体系与教学模式面临着时代变革的挑战,个性化学习、终身学习,以及学习型社会建设已经成为时代发展的必然需求。一种可以随时随地进行学习的移动学习方式是未来远程学习的发展趋势。作为一种新兴起的移动学习方式,近年来越来越受到学习者们的欢迎,这种学习方式不仅成为学习者学习方式多样化的补充,而且已成为现在远程学习的一种主要学习方式,同样在我国的现代信息化教育中发挥着越来越重要的作用。与此同时,随着移动通信技术和计算机技术的迅速发展与融合,使得各种各样的、便携易用的智能移动终端设备不断涌现,移动网络给用户所带来的服务和容量不断提高。“移动”正成为未来技术发展和社会变化的主题,“移动”与“教育”的联结也成为教育信息化应用的重要发展方向。目前很多高校网络平台和远程教育机构开发了大量的流媒体课件资源,它们主要适合在桌面计算机中使用,但不适合在移动设备终端(如PAD、智能手机等)中直接使用。如何为学习者提供适合移动终端学习的流媒体服务,搭建一个方便的学习平台,是本论文探讨和解决的重点。本论文主要做了一下几方面的工作： (1)从实际用户的应用需求出发,分析了移动学习的国内外研究现状及未来的发展趋势,指出了移动学习环境下的流媒体教学资源在利用过程中所存在的问题,为原型系统开发中的需求分析作了基础准备。 (2)在系统开发技术方面,首先对流媒体技术的概念、特点、传输方式和传输原理等进行了详细介绍,重点对交互式网页媒体播放器FLV、开源代码流媒体服务器Red5等进行详细分析,同时对系统开发技术J2EE和Java Web进行了详细的介绍,为后续的系统研究与开发打下了技术基础。 (3)在系统功能模块设计与系统的原型实现方面,给出了系统的功能设计和原型系统设计,该系统涉及的主要服务模块有消息传输模块、视频搜索引擎模块和视频文件转换格式模块,同时给出了系统操作流程图和部分数据库的结构设计最后给出了原型系统实现中的基本结构,并且详细的展现了各个功能模块的实现界面和操作流程等,基本实现了学习者对视频学习资源的观看、评论和搜索,能够满足移动学习环境下的基本功能需求,为学习者的移动学习带来方便和快捷。
[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.
