基于网络的英语在线考试系统

随着Internet技术的迅速发展，高校校园网建设的逐步完善，传统的考试方式已经不能适应现代化考试的需要。Internet技术的发展为标准化考试提供了广阔的发展舞台，在网络下开展的远程测试，具有传统的考试模式无可比拟的优点。开发基于ASP的在线考试系统，将减轻教师的工作量，彻底改变考试中存在的人为因素，提高考试质量，为学生提供一个公平、公正的考试环境。
利用网络和数据库技术，本文设计了基于B/S模式，服务器端采用Access数据库系统和ASP组件构成的考试系统，客户端采用浏览器来完成考试全过程，同时可进行远程系统维护和管理。它运用方便、操作简单，效率很高。具有试题录入、修改和查询，手工组卷与自动组卷以及进行在线考试等重要功能，也就是说实现了真正的无纸化考试，满足考生随时随地考试并迅速获得成绩，并给出其详细的成绩分析与试卷评估，大大减轻了教师出题、组卷和改卷等繁重的工作量。

1.1课题背景
21世纪是以信息化为代表的时代。而学校尤其是高等院校作为高等基础教育的基地更加显得信息化对教育的独特作用。网络以其所具有特点为学校的考试提供了一种全新的方法和途径。基于网络的考试系统可以方便学生根据自己条件有选择的进行测试，同时在校老师也可以通过该系统实现对学生学习状况的考察。
正是得益于计算机网络技术的飞速发展，现在很多国内外的大学和社会其他部门都已经开设了远程教育，通过计算机网络实现异地教育和培训。现在，计算机硬件技术的发展已经达到了相当高的水平。但是，远程教育软件的开发目前还处于起步阶段，随着这项技术的不断深入发展，就要求有更好、更完善的软件系统应用到远程教育当中去，这就给软件设计人员提出了更高的设计要求。
在我国，虽然远程教育已经蓬勃地发展起来，但是目前学校与社会上的各种考试大都采用传统的考试方式，在此方式下，组织一次考试至少要经过五个步骤，即人工出题、考生考试、人工阅卷、成绩评估和试卷分析。
显然，随着考试类型的不断增加以及考试要求的不断提高，教师的工作量将会越来越大，并且其工作将是一件十分烦琐和非常容易出错的事情，可以说传统的考试方式已经不能适应现代考试的需要。随着计算机应用的迅猛发展，网络应用不断扩大，如远程教育和虚拟大学的出现等等，且这些应用正逐步深入到千家万户。
人们迫切要求利用这些技术来进行在线考试，以减轻教师的工作负担及提高工作效率，与此同时也提高了考试的质量，从而使考试更趋于公证、客观，更加激发学生的学习兴趣。例如目前许多国际著名的计算机公司所举办的各种认证考试绝大部分采用这种方式.
