摘 要
　　
隨著信息技術(shù)的發(fā)展和網(wǎng)絡(luò)的優(yōu)化，計(jì)算機(jī)的運(yùn)用變得更加多樣化，而且對(duì)于現(xiàn)代教育來(lái)說(shuō)，傳統(tǒng)的考試模式已經(jīng)不再適應(yīng)，計(jì)算機(jī)的無(wú)紙化考試將會(huì)成為未來(lái)考試的主導(dǎo)。這種方式不僅方便、高效，而且保密性強(qiáng)，解決了評(píng)分時(shí)人為因素的影響。本設(shè)計(jì)運(yùn)用了Visual Basic 6.0和Access數(shù)據(jù)庫(kù)對(duì)《Matlab和系統(tǒng)仿真》一課進(jìn)行了無(wú)紙化考試的設(shè)計(jì)與實(shí)現(xiàn)，實(shí)現(xiàn)了老師的教考分離，解決了人工出題的不可重復(fù)性。該系統(tǒng)實(shí)現(xiàn)了客觀題的隨機(jī)抽取和自動(dòng)組卷功能，并且具有考生登錄時(shí)的身份驗(yàn)證，答題結(jié)束時(shí)的答案提交，答題結(jié)果顯示和自動(dòng)評(píng)分以及自動(dòng)計(jì)時(shí)功能。由于系統(tǒng)采用了Access數(shù)據(jù)庫(kù)，所以方便了數(shù)據(jù)庫(kù)的更新、管理和維護(hù)。該設(shè)計(jì)保證了考試的客觀性、實(shí)時(shí)性和公正性，而且降低了老師在出題和閱卷時(shí)的工作量。

Design of Examination System Based on VB and Access

ABSTRACT

　　
With the development of information technology and network optimization, the application of computers is more varied. For modern education, Traditional exams is no longer suitable , the paperless examination of computer will led the future examinations, this approach is not only convenient, efficient ,but also confidential in nature, and it will solve the problems of human factors. This design uses Visual Basic 6.0 and Access database right, design paperless examination of Matlab system and Simulation and the separation of education and examination, it solves the problem of non-repeatability. The system achieves the selection of objective title randomly and automatic Test Paper, it also has the candidates login authentication, Hand over the answer at the end of examination, and the answer showed, automatic scoring and the automatic timing. As the system uses the Access database, so it facilitates the updating of the database, management and maintenance. The design ensures the examination to be objectivity, impartiality and real-time, lowers the teacher’s workload in making out questions and scoring.

Keywords: exam system　　forming examination papers in random　　automotive grading　database
