基于J2EE的學(xué)生在線考試系統(tǒng)設(shè)計(jì)與開發(fā)

摘 要
智能化遠(yuǎn)程考試系統(tǒng)是遠(yuǎn)程教育系統(tǒng)的重要組成部分，是實(shí)施個(gè)別化教學(xué)的有力工具，具有廣闊的應(yīng)用前景。該文給出的考試系統(tǒng)模型提供了四大功能模塊，形成了強(qiáng)大的試題庫(kù)建設(shè)管理與完整的試卷智能生成，自動(dòng)跟蹤閱卷、綜合智能評(píng)價(jià)，數(shù)據(jù)智能分析以及學(xué)習(xí)指導(dǎo)等功能，具有很強(qiáng)的學(xué)科通用性，是改革傳統(tǒng)考試形式和實(shí)現(xiàn)考試系統(tǒng)智能化控制的一種新的探索。關(guān)鍵實(shí)現(xiàn)了考生在選擇科目后進(jìn)入考試窗口，考試計(jì)時(shí)，考試時(shí)間到時(shí)系統(tǒng)強(qiáng)制考生退出，及考完后對(duì)客觀題的自動(dòng)評(píng)分、存檔和考后試卷復(fù)查以及柱狀圖分析等功能。

Abstract
Intelligent distance Exam System is an important part of Distance Education System, a powerful tool of individual education. It has a good future in application. This paper introduces an intelligent distance exam system that includes four main function modules. This system has several features such as item bank constructing and managing, intelligent test-paper generating, auto paper tracking and evaluating, intelligent data analyzing and studying guiding. This system can be used in different courses. It is a new attempt in traditional exam reform and intelligent control of exam system. The system pivotally realizes that when the examinee to enter the test window after the choice subject, the test begin to time, if the time is used up, the system forced the examinee to withdraw. After testing the point and answer are memorized into system automatically. The system also realizes recheck examination paper after testing and analyse it with histogram.

【Key Words】model-view-control , intelligent distance exam, auto paper tracking, score inquiry, intelligent data analyzing
