基于JSP技术的在线考试系统的设计与实现

摘要
随着计算机网络及其相关技术的不断发展，计算机网络技术在教育领域的应用已经一发不可收拾。特别是在考试手段和媒介上，传统的考试方式和手段正面临着巨大冲击。基于JSP技术的在线考试系统，发挥着现代网络的优势，突破了时间与空间的限制；同时，建立了大型、高效、共享的题库，大大改善了考试工作的效率。
本系统是基于JSP技术，采用B/S三层构架作为体系结构，以Tomcats作为Web服务器，后台数据库采用ACCESS数据库，进行开发的在线考试系统。
系统采用经典测试理论作为建库理论，并运用了结合潜在倾向的方法来确定试题难度系数，使试题的难度系数趋于客观。本设计的创新之处还在于使用了兼顾章节比例并按照教师制定的组卷策略随机生成试卷的智能组卷方法，保证考生试卷雷同率低，同时避免考前的试题泄密，确保考试公正。

关 键 词 ：在线考试系统，建库理论，智能组卷，B/S模式，JSP，JavaBean，Servlet，ACCESS数据库。

ABSTRACT
     As computer networks and related technology development, computer network technology applications in the field of education has run out of control. Especially in the examination on the means and media, the traditional ways and means of examination are faced with tremendous impact. JSP technology-based online examination system, exert the advantages of modern network have broken through the restrictions of time and space . At the same time, set up a large-scale, high efficiency and shared data bank, has greatly improved the efficiency of the examination.
     The Online Examination system is development based on JSP technology,used of B/S three-tier architecture as the architecture , used of tomcats as the Web server, back-end database using ACCESS database.
     System using the classical test theory as database theory, and using a combination of a potential method to determine the orientation test the degree of difficulty, so that the difficulty of the questions tend to objective factors. This system innovation also lies in the use of both sections of the proportion of teachers drawn up in accordance with the randomly generated papers Strategy Paper of the Intelligent Test Paper Method.With Intelligent Test Paper Method to ensure that candidates similar to the low rate of examination papers. At the same time , test questions to avoid leaks before the examination, ensure that a fair examination.

Key  Words: Online Examination System, Database Theory, Intelligent Paper, B / S Mode  Structure, JSP, JavaBean, Servlet, ACCESS Database.
