信息管理论文：光电学院网络教育电路课程在线考试系统

1、信息管理论文：光电学院网络教育电路课程在线考试系统【中文摘要】近年来，网络技术的飞速发展和计算机应用技术的 普遍普及，国内、国外的许多学校先后建立了自己的校园网平台，为远 程网络教育的实现打下了良好的基础。从我国高校教育教学的效率角 度来看,用纸和笔为主要工具的传统考试方式的弊端越来越的显现。 题目内容的设计、试卷的组织、印刷、分发、考试、试卷评阅等都将 耗费大量的人力和物力，而且工作效率极为低下，主观性很强，要依靠 传统的教育考核方式来实现提高教育效率和考试公平性是非常困难 的,借助网络教育形式来发展、扩充高等教育，使用在线考试的方式是 今后高校考试发展的必然趋势。而在线考试系统作为网络教育

2、的重要 组成部分，已经成为许多机构进行研究的热点课题。目前，网络应用软 件运行的模式主要有二类：Client/Server模式,Browser/Server 模式。前者主要的缺点是维护、升级较麻烦，后者是近几年伴随 In ter net 迅速发展起来的一种技术，它与客户/服务器方式类似，客户端只需一 个标准的浏览器，服务器端是 Web Server ,而 Web Server 与数据库 和应用服务器的紧密结合，使得这种模式的应用范围不断扩大，它的 主要优点是便于扩充应用、升级、维护简便。基于上述考虑，用Browser/Serve 模式来设计考试系统比较合适，服务器端我采用 Access数据库系

3、统、JAVA 组件、WEBS 件和 Tomcat 来构成考试的应 用服务系统，客户端采用浏览器来完成考试全过程，同时系统管理员 可进行远程系统维护和管理。本课题的主要阐述在线考试系统的后台操作过程及一些关键技术：首先该系统管理用户信息从数据库直接录 入。系统管理用户创建考试管理用户、考试用户信息数据库、试题数 据库和管理维护系统。然后考试用户登陆考试系统，选择考试后进入 考试窗体,后台处理程序针对登录的考试用户信息，进入试题数据库 按照试题类型的比例随机抽取适合当前考试用户的所有试题，将抽取到的试题和答案随机排序后生成试卷给考试用户，可有效防止相邻考 生互相窥视，这样保证考试的真实性。考试用户

4、完成本次考试，提交试 卷后,系统将统计本张试卷的考试成绩，将考试成绩返回给考试用户，同时写入考试成绩数据库存档。【英文摘要】In recent years, along with the highlydevelop ing n etwork tech no logy and populariz ingcomputer skilland campus n etwork built up in lots of schools either in our country oroversea, distance& online education has got a strong techni
