1、……………………………裝……………………………………訂…………………………………線……………………………1計(jì)算機(jī)在線考試系統(tǒng)摘要隨著社會(huì)信息化程度的不斷提高,計(jì)算機(jī)應(yīng)用能力的培訓(xùn)得到迅猛發(fā)展,考核中使用的傳統(tǒng)手工閱卷己經(jīng)逐漸走向計(jì)算機(jī)自動(dòng)評(píng)閱。目前自動(dòng)閱卷己經(jīng)能很好地完成對(duì)常見(jiàn)客觀試題的自動(dòng)批閱工作。本文討論了計(jì)算機(jī)在線考試系統(tǒng)的設(shè)計(jì)與實(shí)現(xiàn)技術(shù),結(jié)合實(shí)際提出本系統(tǒng)的總體結(jié)構(gòu)和功能模塊,然后通過(guò)系統(tǒng)結(jié)構(gòu)設(shè)計(jì)、表的設(shè)計(jì)及前端開發(fā),構(gòu)建了一個(gè)基于C/S結(jié)構(gòu)和SQL后臺(tái)數(shù)據(jù)庫(kù)為基礎(chǔ)的系統(tǒng),具備以下功能:學(xué)生數(shù)據(jù)維護(hù)、試題信息維護(hù)、考場(chǎng)設(shè)置、試題模板設(shè)置、自動(dòng)組卷、
2、自動(dòng)分配座次、考場(chǎng)自動(dòng)監(jiān)控、自動(dòng)評(píng)分、院系專業(yè)等信息的維護(hù)、用戶管理、數(shù)據(jù)庫(kù)備份和恢復(fù)等功能。在實(shí)現(xiàn)方法上,使用Visio完成前期數(shù)據(jù)庫(kù)設(shè)計(jì),采用ASP.NET開發(fā)環(huán)境和C#語(yǔ)言,實(shí)現(xiàn)C/S結(jié)構(gòu)下與數(shù)據(jù)庫(kù)之間的連接,采用隨機(jī)自動(dòng)抽題組成試卷,可以實(shí)現(xiàn)數(shù)據(jù)備份,重點(diǎn)對(duì)題庫(kù)操作的方便性、兼容性,自動(dòng)組卷的不重復(fù)性、合理性,自動(dòng)評(píng)分技術(shù),和考試系統(tǒng)的合理性、界面的人性化進(jìn)行了考慮。關(guān)鍵字:上機(jī)考試系統(tǒng);C#;C/S;自動(dòng)組卷;自動(dòng)評(píng)分;.NET;I……………………………裝……………………………………訂…………………………………線……………………………山東科技大學(xué)
