通用网络考试系统的计与实现.docVIP

摘 要 随着计算机网络的普及，利用网络环境进行考试成为教育考试发展的一个趋势。本文分析了目前己经存在的考试系统的特点，提出了一个构建通用网络考试环境的新思路，使考试系统既可以进行常规的标准化考试，又可进行主观型试题考试：即可进行理论知识的考试，又可进行考查应用软件操作技能方面的考试。本文给出了这一考试系统的设计与实现方案，并对设计过程中的一些技术要点进行了分析介绍。 这个考试系统分为三个独立运行的子系统： 1．教师工作子系统； 2．考试过程控制子系统； 3．考试服务器子系统。 该考试系统满足了用户对于考试系统的以下几个方面的需求： 1．教师能够建立试题库、设计试卷，并将试卷传送到考试服务器； 2．教师可以下载试卷包并对主观型试题进行阅卷； 3．考生可以在网络内的一台计算机上登录到考试服务器，参加考试； 4．考试服务器可以控制试卷的打开、关闭、打包等； 5．考试相关的数据应当在网上准确、安全地传递。 该考试系统在设计中比较有特色的方面有以下几点： 1．既可进行标准化的客观型试题考试，又可进行主观型试题考试； 2．既可进行理论考试，又可进行软件的操作考试； 3．考生客户端程序可免安装运行，系统构建简单； 4．考试过程异常中断时，可安全准确恢复考试过程； 5．考试系统具有通用性，不受学科限制。 关键词 MFC；DAO；ADO；考试系统 Abstract As the computer network spreading to everywhere of the world , Network - Exam 15 becoming the trend of educational exam． In this thesis, the author bring forward a new idea for constructing a network exam system.
