开放式考试平台的设计与实现

Design and implementation of open examination platform

为了实现传统考试流程的网络化、自动化和无纸化,突破基于题库组建试卷的思维定势,研究开发了基于试卷的开放式考试平台。该平台不需要建立题库,支持教师自主创建与维护试卷,设置个性化考试和下载考试结果,可以防替考、防抄袭、防故障,自动评分并生成带批阅记录的答卷。分析了系统参与者与功能需求,建立了用例模型和数据模型,提出了功能设计和流程设计,给出了主要功能的实现方法和关键代码。经2万余人次考试验证,该平台能够满足通用考试需求。

To achieve the networking,automation and paperless of traditional examination process,the thinking set that exam papers should be generated by given test database is broken,an open examination platform based on individual exam papers is discussed and developed.The platform does not require creating test database,supports teacher creating and maintaining of their own exam papers,setting of individuation examinations,downloading of final results.Behaviors of imposition,plagiarism,as well as system breakdowns are all prevented by the platform.After automatic scoring,answer sheets with the marking record will be generated automatically.The platform actors and their functional requirements are analyzed,the use case model and data model are created,the function design and process design are presented,while the main implementation methods and key codes are given.Verified by examination results of more than 20,000 people verify,the platform is able to meet the demand of general examination.
