The Research And Realization Of Automatic Marking Technology For Visual FoxPro Programming Papers

The background of the thesis is the actual demand of the Education Department of Liaoning Province, which studies a new development trend in the field of Computer Assisted Assessment (CAA), that is Computer Test Automatic Assessment(CTAA).Today, computer knowledge is the basic quality for college students. Now, many universities have introduced information technology curriculum, its objectives should be training studentsand making them into Compound talent.Because of its particularity, the system of knowledge of computer subject differ from other subject . So the appraisalfor this subject is differ from other subject. If doing it traditionally, it will not be objective and fair.The national university's computer examination of Liaoning Province, which is organized by the Entrance Examination Office of the Education Department of Liaoning Province at present is divided into three grades, two among which provides 5 kinds of programming languages for examinees to choose. After great amount of requirement analysis, the author knows the actual demand very well and chooses Visual FoxPro programming topic to conduct the research. After consulting great deal of literatures and using existing advanced technology for reference, the author puts forward a resolvent for Visual FoxPro papers automatic marking technology. That is Visual FoxPro programming automatic marking technology based on some key steps such as program run, program test, the key point analysis and result judging, avoiding unscientific evaluation of some existing system by giving extreme score from simply judging whether the result is right or not. The author also put forward some algorithms, which makes the score of programming more objective and reduces the error rate of marking test papersAt present, the study and realization of the technology is conducted to meet the demand of the Entrance Examination Office of the Education Department of LiaoningProvince, therefore the application of this technology is still narrow. The consequent study will concentrate on more general automatic marking papers technology for computer programming and the further expansion will be made in order to popularize and apply the technology more widely.
