The Design And Realization Of The On-line Examination System Based On SNS

With the development of society, the rapid development of information technology,the paperless office and use are more and more widely, also, we often meet diverseexaminations in learning and working, the types of examinations are increasing, therequirements of examinations improve continuously, and the workload of teachers ismore and more big. In this case, the teacher’s job will be a very cumbersome and errorprone. The traditional examination method has exposed a lot of problems, therefore, thiskind of examination method can’t adapt to the demand of the modern examination,which requires a convenient, practical examination of ways to replace it. With thedevelopment of computer technology, developed model test has been great changes,then the paperless examination becomes.This paper researched the online examination system and it based on SNS; thesystem has good openness and versatility, and can be suitable for multi-functionalexamination.The main research includes the objective questions test (i.e., fill in the blanks,multiple choice, matching problem), environment simulation and automatic scoring, ofwhich the latter two are the focus of this paper. The system mainly consists ofgenerating paper module, online examination, multi condition query, automatic scoringfunctions; system can achieve the fast computation speed, high accuracy, impartialyassess the real level of the students; automatic marking and online examination functionachieve the examination of the information and "paperless" target. It improves thestudents’ assessment efficiency, saves the manpower resources and cost, enhances theauthority and impartiality of the examination.The system uses the.NET development platform, the development tools usesMicrosoft Visual Studio2010integrated developed environment, the programminglanguage used C#programming language to program, the database we used is thecurrent popular SQL Server2008database management system, it stores data in theinformation platform, and the system uses the B/S framework for development. It canplatform architecture to a service and Internet users provide a complete service. Nowtest platform has a variety of environment, and has been running for more than twomonths, the user reflects well. For the system officially launched the use of layont is a good foundation...
