B-learning教学平台的设计与实现

摘要
随着计算机网络的迅速发展和教育对计算机网络的资源需求，从20世纪90年代开始，E-learning（数字化或网络化学习）成为很多人关注的热点。近几年来，E-Learning快速发展，但是从2001年开始，E-Learning出现了停滞不前的情况，国外关于E-Learning的研究逐渐进入下滑阶段，国外教育技术界和企业培训界逐渐意识到用混合式学习（Blending Learning，以下简称B-Learning）理论来协助和优化传统的E-Learning。现在B-Learning已经成为教育技术界高度关注的热点之一。 B-Learning最主要的目的就是要把E-Learning的优势和传统的课堂学习优势融合在一起，换句话说，其实就是要同时兼顾教师在教学过程中的主导作用和学生在学习过程中的主动性、积极性以及创造性，从而使教学效果达到最优化。
本文在第一章分析B-Learning的意义，国内外现状，存在的问题以及本人研究的内容和目标。第二章详细的分析了B-Learning系统开发的关键软件技术，涉及到的类图以及用况图。第三章介绍系统的实现平台以及对开发工具Flex技术、 MyEclipse6.5、tomcat6.0与SQL server进行介绍。第四章总结在这次开发过程中学到的各种技术。

ABSTRACT
With the rapid development of computer networks and educational resources on the computer network needs, from the 20th century, 90 years, E-learning (digital or network learning) as the focus of attention of many people.In recent years, E-Learning rapid development, but since 2001, E-Learning has stalled situation, foreign study on E-Learning into the decline stage gradually, foreign educational technology community and the corporate training sector gradually became aware of with blended learning (Blending Learning, later referred to as B-Learning) theory to assist and optimize the traditional E-Learning. Now B-Learning has become the education technology industry hot topic of great concern. B-Learning main purpose is to bring the advantages of E-Learning and the advantages of traditional classroom learning together, in other words, in fact, must balance the teaching process, teachers and students in the leading role in the initiative in the learning process , enthusiasm and creativity, so that teaching effectiveness is optimized.
This article in the first chapter of B-Learning the meaning of status quo at home and abroad, problems, and I study the content and objectives. Chapter II detailed analysis of the B-Learning system development of critical software technologies, involved in the class diagram and use case diagram. The third chapter describes the System platform and the Flex development tools, techniques, MyEclipse6.5, tomcat6.0 and SQL server are described. Chapter IV summarized the development process in a variety of techniques learned.
