The Design And Research On The Computer Aided Test System

With the development of society's information technology,the tradtional teaching in education can't satiefy students' requirement to diversificational knowledge for student.A variety of computer aided Instrucation software have been applied for the teaching pratice from primary school to campus.Thesegment of teaching-------compterization in examination have caughteverbody's eyes more and more.The computer aided test can relief teachers' work in examination. For example,papers organization test,marks determinant .result analysis .it will deduce the factor that people bring in mind subjiectively.anf orginaze the test safelier ,more quickly and more impersonal it can promote the teching quality and efficiency. For students,specily in internet ,time and address are not questions.today,the compter aided test have been apply for the all kind of testWe wil intrduce toyou the computer test based on database.There are two kind of test mode,one is classical test, that is to select item from item bank,use the same paper to test different students.the other is CAT(computer adaptive test), which use different paper to test different students .CAT can measure more quickly and easy,it can reach the same precision with only half time and about 40% quantity of written examination . in the test ,the test parameters have nothing to do with students' quality,the final mark also be free with test items.the classical test fixs in with speculate habits,but is impacted on test items.because of the computer adaptive test's techology is very complex and test items work is too hard,point blank and concision aren't same as the classical test,it can't carry forward as that onehi this paper, compare two kinds of test to seek the best way to measure students quality subjectively and analys after examation.Based. on database and conect with the current condition on the examination theory ,Wuhanchemical college computer test system aim at the characteristic of the basic computer,use this kind of manner to realize test without paper, in wuhan chemical college we design the the whict computer aided test,use the diffent mode in the different condition. .The clasical test is always used in the final test in term, give a certain point to students according with the present teaching system. The comupter adaptived test is used in trainingto find students'shortage.The whict computer test can accord to the teaching evaluation system to analyse students'capacity and papers'quality for improving our teaching molar.
