The Research On Automatic Test Scheme For Online Examination System

With the rapid development of network technology and computer technology,teaching model is undergoing changes.Today,people acquire new knowledge through the network to learn skills.Due to the rich learning resources,new forms,great development potential,and internet-based education has become a strong complement to modern education.Diversification of online teaching resources,digitization and storage make it possible to teach different people at different time and places.In the paper,based on B / S structure,SQL server database and ASP technology to Apache is used as a system server.A reliable online examination system is investigated.The functions are including as student registration,student login,password changes,results inquiries,network test,security exit and background student information management,teacher information management,test information management,content management questions,questions adding categories and exit management.In the existing online examination system,the examination is limited with content unified and not ensure the expansion of knowledge.In the paper,a method of automatic test paper,randomly selected from the question set is investigated.The questions knowledge can be coverage and reflects the degree of difficulty the questions of automatic test paper.Meanwhile,the cache and recovery for the candidates answer are studied.The experimental results show that the online examination system is capable of running,the user's request can be responded within a very short time.And the occupancy rate of network is less than 12%,in addition,the data transfer of online examination system between the various sub-modules can be implement and the packet loss rate is 0.02%.
