高等职业院校在线考试系统的设计与实现-软件工程专业论文.docx

中文摘要中文摘要随着高职院校招生规模的不断扩大，每个学期期末考试的工作量日益增多，以纸和笔为主要工具的传统考试方式的诸多弊端越来越明显地暴露出来，网络考试显现出其广阔的前景。针对这些现状，特开发此在线网络考试系统。本文首先讨论了选题背景、国内外研究现状与水平、研究意义、研究内容、及课题中的难点及解决办法。同时对系统的需求及可行性进行分析和研究，介绍实现系统的相关理论基础及技术和系统的总体结构设计与及功能描述；以实现《C 语言程式设计》在线考试为例，阐明了组卷算法的数学模型及算法研究及评分算法改进技术。针对客观题和主观题不同的特点，客观题采用精确匹配方式，主观题采用采用静态评分阅卷与动态评分阅卷相结合的方法完成对题目的评分阅卷；本系统采用C／S架构实现，依托高职院校现有自身的校园网络进行设计。系统分为三大模块：题库管理模块、考试模块和评分处理模块。阅卷系统采用MicrosoftVisualBasic6．0与C语言混合开发。系统利用Delphi、TCP／IP技术，VisualBasic和C语言及编译原理的相关知识。关键词：考试系统；组卷；B／S模式：自动评阅J··FEV.‘可hF1 IIYIIql l鸳{炒掣翌掣1攀lll7lllll黑龙江大学硕士学位论文AbstractWiththegrowingenrollmentinvocationalcollegesandtheever--increasingworkonthefinalexaminationsineachsemesteraccordingly,thedrawbacksofthetraditionalexaminationpattern,、Ⅳimpaperandpenbeingthemaintools，haveemergedmoreandmoleobviously,andthusnetworkexaminationsshowtheirpromisingfuture．Todealwiththecurrentsituations，theonlineexaminationsystemisdeveloped．，，T_=First,thethesisdiscussesthebackgroundoftheselectedtopic，theresearchstatusandlevelathomeandabroad,theresearchimplication,theresearchcontentsandldifficultiesandsolutionsoftheproject．Furthermore，theanalysisandresearcharecarriedoutonthedemandsandfeasibilityofthesystem；thethesisintroducestherelevanttheoreticalfoundationfortherealizationofthesystemandtheoverallstructuredesignofthetechnologyandsystem，andthethesisalsodescribesthefunctionsofthesystem；thethesistakestheonlineexaminationusingCLanguageProgramDesignasanexample，illustratingtheimproved techniqueinscoringalgorithm．Basedonthedifferentcharacteristicsofobjectiveandsubjectiveitems，exactmatchingmodeisll■rl’lI【|adoptedinobjectiveitemsandstaticscoringiscombinedwithdynamicscoringtomarkthesubjectiveitems．ThesystemisimplementedwithC／Sframework,anddesignedonthebasisoftheexistingcampusnetworkwithinvocationalcolleges．Thesystemconsistsofthefollowingthreemodules：itembankmanagementmodule，examinationmoduleandscoringprocessingmodule．ThescoringsystemisdevelopedwiththecombinationofMicrosoftVisualBasic6．0andCLanguage．ThesystemadoptsthetechnologyofDelphia
