隨著信息技術、特別是網絡技術和多媒體技術的飛速發展,以網上交互式學習為主要特點的網絡教育在中國得到了巨大發展,已成為中國大眾化高等教育的重要組成部分。網絡教育給教育帶來的革新不只是一種新的學習手段,而是對整個教育思想和觀念帶來了巨大的變革。通過網絡人人都可以隨時隨地進行學習,教育不再是只能在學校進行,而是一種社會化的行為,學習不再只是在一定的時間專門進行,而是成為人們生活的一部分。中國的網絡教育起步于1998年,至今已經過6年半的發展期,形成了一定的規模,積累了豐富的經驗,創造了自己的模式,獲得了很好的效益,但同時也還有許多必須直面的挑戰和問題,其主要因素是學習支持系統的建設。
本文的研究課題是設計《網絡教育》這門學科應用于網絡的教學支持系統,在系統的設計中采用了B/S網絡結構模式來構造整體框架,以SQL SERVER為存儲數據庫,利用Visual Studio .NET 2003開發主要界面,并結合功能強大而靈活的ASP.NET工具實現整個系統的程序設計。由于不僅限于一門學科,特別開發了選課系統這一板塊,使學生更能有選擇性的學習課程,使這個基于web形式的教學支持系統更加的強大,它不僅實現了客觀題的網上教學,而且實現局域網用戶(校內)和Web用戶(校外)的實時/非實時的教學功能。

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.
