摘 要:随着Internet技术飞速发展,我们生活中的每时每刻都能享受到网络带来的迅捷、便利和惊喜。网页是网络的重要组成元素,它直接体现着网络信息的丰富多彩。建立实验课程网络教学平台就是依托于网页的模式,将教学资源整合在网络上,依靠网络的快捷性、实时性、简约性,跨越了时间和空间的限制,实现学生与教师交互性实验教学的目的。
实验课程网络教学平台的开发采用C/S的双层结构模式,使用asp动态网页技术、VBScript脚本语言、Access数据库和HTML超文本标记语言结合编写。平台中中共存在两个主体:学生、教师(管理员)。此教学平台分为前台的实验中心信息浏览、查询、资料下载和后台的管理、数据库维护两大部分,通过网络为学生提供一个面向目标的实验学习环境,实现个性化教学的目的。
最终,该教学平台的成功开发完成了毕业设计要求的任务,达到了实验教学和管理的目的。本文对数据库设计、程序设计和实现、系统安全进行了详细论述。

Abstract
As the dramatic development of Internet technology, we experience and enjoy the swiftness, convenience and surprises it brings everywhere and every time. Web page is an important element of Internet, reflecting directly the variety and diversity of Internet information. To establish an Internet experimental teaching platform is equal to integrate the teaching recourses on the Internet, through the method of web page. Making full use of the swift, real-time and simple Internet, this platform will make the aim of interactive experimental teaching between and among the teachers and the students come true, overcoming the barriers
of time and space.
The Internet experimental teaching platform adopts the C/S double-decked structural pattern by use of ASP dynamic web technology, VBScript scripting language, Access databases and HTML. There are two subjects: students and teachers (administrators). It includes two parts, that are the front experimental centre for information browse, inquiry and download, and the background processing and data maintenance. This platform will achieve individualized teaching, providing the students with a goal-oriented experimental learning environment through Internet.
At last, the successful research and development of that teaching platform finish the task and meet the requirement of graduation design, accomplishing the aim of experimental teaching and administration. This paper will give a detailed introduction of the database design, process design and implementation of system security.

1.1 课题背景
随着网络教育的蓬勃发展,与之相适应的资源建设也日益受到人们的重视。众所周知,网络教育有三大基础:硬件、软件和网络教育资源。随着Internet技术及其向宽带、高速、多媒体化方向的快速发展,硬件、软件方面的优势将逐渐弱化,教育资源的优势必将越来越重要,最终将决定网络教育成败的关键所在,而网络教学是其中非常重要的组成部分。网络使教与学活动产生了时空的分离,教师不再是直接的教育者,教育目标通过网络教学来实现,教学活动围绕着网络教学平台展开,因此开发适用于网络教育的高质量的网络教学平台成了我国发展网络教育的一个非常重要而迫切的课题。
网络应用于教育领域,给人们提供了大量便捷的学习机会、丰富的教学环境和教学资源,使学习活动更加交互化、自主化、个性化,使教育的适应性得以大大加强。
