2011 年 12 月 10日 摘要 考试是教学至关重要的一个环节，是检查学生对知识掌握程度的尺码，也是测评任课老师教学效果的标准，然而这又会受到考试本身质量的影响。 随着网络技术的发展，网络教育得到前所未有的发展，传统的考试方式的种种不足和局限日益显露。如传统考试方式从组卷命题、试卷印刷，考场安排、监考到组织判卷都是通过人工操作完成，所以周期长、浪费大、效率低；教师的工作量大，教师要承担包括试卷出题、审阅批改、统计分数等高强度的体力劳动，耗费了量大的工作时间和精力等等。因此改革传统考试迫在眉睫。以网络技术为支撑的现代计算机应用，已经具备较大的规模并相当普及。作为对传统考试模式的改革和创新，利用计算机技术实现无纸化考试，取代纸和笔的传统考试方式，是近年来计算机技术的一个非常活跃的研究领域。 本文描述了一个随机组卷的在线考试系统的设计过程。文中就Browser/Server模式的特点首先做了分析，给出了Browser/Server模式的两个重要特性，系统维护方便和硬件无关性。因此在随机组卷的在线考试系统中采用这种结构是可行的。提高Web软件维护性的一个方法就是将软件的表示和逻辑部分分离，JSP恰恰能实现这种分离。于是JSP被应用到随机组卷的在线考试系统的开发中，以确保系统的安全性、可维护性和易操作性。 关键词：Browser/Server；JSP；网络技术；随机组卷的在线考试。
Abstract Teaching examination is a critical part of the students is to check the extent of the knowledge of the size, but also survey datum related to the effect of teaching standards, but this will be the quality of the examination itself. With the development of network technology, and network education be an unprecedented development, the traditional examination of the way the inadequacies and limitations of the increasingly exposed. Such as traditional examination mode from Test Paper proposition, printing papers, examination arrangements, the organization Panjuan invigilators are completed through manual operation, so long cycle, waste and low efficiency; the workload of teachers, including teachers to bear that out papers , examine correcting, the Census and Statistics scores of high intensity manual, spent a large amount of time and energy, and so on. So the imminent reform of the traditional examination. Technical support for a network of modern computer applications, already has a larger scale and popularity. As a model of the traditional examination of the reform and innovation, using computer technology to achieve paperless examination, replacing the traditional pencil and paper test, the computer technology in recent years is a very active research field. This paper describes a random Test Paper online examination system design process. In the Browser / Server model to the characteristics of the first analysis, given the Browser / Server model of two important characteristics, the system easy to maintain and hardware independence. Therefore, in Random Test Paper online examination system used in such a structure is feasible. Improve Web software maintenance is a method of software that will be part and logical separation, JSP precisely to achieve such separation. JSP therefore be applied to random Test Paper online examination system development in order to ensure the security of the system, maintainability and easy operability. Key words: Browser/Server; JSP; network technology; a random online examination system. 目录 第1章 引言 ............................................................ 1 1.1 开发背景 .......................................................... 1 1.2 开发意义 .......................................................... 1 1.3 网络考试的优点 .................................................... 2
