基于B/S模式的网上考试系统的设计与实现

Design and Implementation of the Online Test System Based on B/S Mode

为了减轻教师的工作负担,使考试更趋于规范、公正,设计了一个适应于所有计算机科目的网上考试系统.该系统克服了以往网上考试系统的一些弊端,具有组卷算法先进,满足主观题、客观题测试,对意外中断及时处理,采用语义理解的主观题自动阅卷等特点.重点设计试题库维护、自动组卷、在线考试、自动计时、自动阅卷等模块的具体功能,对考试页面的自动计时给出算法实现.通过测试表明,该系统具备良好的安全性、稳定性及通用性.

In order to reduce the burden of a teacher＇s work, in order to make the test tend to be more standardized and just, a system suitable for all computer course online examination is designed. The system overcame some previous online examination system handling drawbacks. The system has such features as ad- vanced sets algorithm, subjective items, objective questions test, accident interrupts in a timely manner, auto- matic marking of subjective questions etc. Other key design functions are examination maintenance, auto-gen- erating test paper, online test, automatic timing, automatic marking of the specific function module. The realiza- tion of the algorithm about test page automatic timing is given. Through the test it shows that the system has good security, stability and universality.
