基于B/S模式的网上考试系统的设计与实现

摘要

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.
