随着信息技术、特别是网络技术和多媒体技术的飞速发展,以网上交互式学习为主要特点的网络教育在中国得到了巨大发展,已成为中国大众化高等教育的重要组成部分。网络教育给教育带来的革新不只是一种新的学习手段,而是对整个教育思想和观念带来了巨大的变革。通过网络人人都可以随时随地进行学习,教育不再是只能在学校进行,而是一种社会化的行为,学习不再只是在一定的时间专门进行,而是成为人们生活的一部分。中国的网络教育起步于1998年,至今已经过6年半的发展期,形成了一定的规模,积累了丰富的经验,创造了自己的模式,获得了很好的效益,但同时也还有许多必须直面的挑战和问题,其主要因素是学习支持系统的建设。
本文的研究课题是设计《网络教育》这门学科应用于网络的教学支持系统,在系统的设计中采用了B/S网络结构模式来构造整体框架,以SQL SERVER为存储数据库,利用Visual Studio .NET 2003开发主要界面,并结合功能强大而灵活的ASP.NET工具实现整个系统的程序设计。由于不仅限于一门学科,特别开发了选课系统这一板块,使学生更能有选择性的学习课程,使这个基于web形式的教学支持系统更加的强大,它不仅实现了客观题的网上教学,而且实现局域网用户(校内)和Web用户(校外)的实时/非实时的教学功能。

Abstract
With the rapid development of information technology, especially network technology and multimedia technology, online education, which mainly focuses on interaction learning online, has been gradually used in China. Online education has become an essential part of mass higher education in China. What online education brings us is not only a new study method, but also great changes on education ideas and concepts. People can learn whenever they want through internet. It means that education is not available in schools only, but that it has become a social manner. And learning becomes an essential part in our daily life instead of learning at a particular time.
Online education was first existed in 1998 in China, and has experienced 6 years’ development till now. It has accumulated a lot of experiences, formed its own pattern, covered certain areas, and gain pretty profits. However, it is faced with unavoidable challenges and problems, because it is learning that support the system construction. B/S mode is used to build the whole frame in system design. SQL Server Database, Visual Studio .NET 2003, and ASP.NET are used in data storage, interfaces design, and system programming respectively. To enable students to learn a course freely, Subject Select Module is designed. Thus, the web-based education supported system is much stronger. It not only realizes objective questions online testing, but real-time/ non-real time education between LAN users (inside) and Web users (outside) as well.
