1、 摘要 随着计算机和网络技术的不断发展，社会的信息化程度越来越高，信息技术 正逐渐渗透到各个领域，网络教学的蓬勃发展就是一个很好的例子。与以往使用 独立的计算机进行辅助教学相比，网络教学利用计算机可以更加有效地利用资 源，并可以通过网络实现老师和学生进行更广泛的交流，能够充分调动学生的主 动性，更好地实施素质教育，符合新时代教育形式的要求。因此，建立一个网络 教学平台势在必行。网络教学系统是在校园网中建立一个辅助教学的 IT 环境， 在这个环境中,可以实现教师备课、课件制作、授课、批改作业、学生自主学习、 在线考试、师生交流、答疑等教学环节。 系统采用了 J2EE 架构，是针对目前教学中存在的
2、问题，结合了网络教学的 主流模式和国内外的最新理论成果，同时采用了目前较为成熟的网络技术。 论文 从网络教学系统的设计目标、用户特点和运行环境出发，详细探讨了系统的需求 和功能特点。以 J2EE 技术、MVC 模式的思想为基础，采用 B/S 多层体系结构， 分析并设计了网络教学系统，提出了一个新型网络教学系统的解决方案，并且对 其中的主要功能作了示例性的实现。 该系统采用了目前流行的技术，增强了系统的可扩展性和安全性，对于教学 网站开发的人员有很好的借鉴意义。 关键词：J2EE 架构，网络教学系统,MVC 框架,B/S 模式 Abstract As the computer and netwo

The network teaching is fit to the requests of education in a new era, and so, it is urgent to build a platform for network teaching.
5、 The network teaching system is used to build an IT environment for computer aided instruction system. In this IT environment, we can use it to prepare lecture, make PPT、 teach、 correct studentspapers、 self-study、 exam on line、 communicate between teachers and students、 answering students questions

System USES a J2EE architecture is aiming at the problems in the teaching, combined with the network teaching pattern and the latest mainstream theory results at home and abroad, and adopted at present relatively mature network technology. Paper from the network teaching system design goal, the user and operation characteristics of environment, detailed the demand of the system are discussed and features. With the J2EE technology, the MVC pattern thought as the foundation, the B/
