Design And Realization Of The On-line Test System Based On B/S Model

With the rejuvenation of educational modes of thought and the development of science and technology, the shortcomings of the traditional examinations are completely exposed. The design, the organization, the printing, the distribution, the process and evaluating of the test take a lot of labors and materials, which shows people's lower working efficiency and strong subjective inclination of the test.In such cases, the computerized test system emerges as the times demand. It will take the place of the traditional test by making use of the computer to manage and possess the item bank, organize the contents and evaluate the test paper. It is characterized in its convenience and fastness in setting a test paper, its speed and accuracy in evaluating the paper and its scientific analysis of the test paper. It is easier for teachers to set a test paper by the item bank system, and it will save a lot of labors in evaluating the test paper. It will greatly improve the accuracy in evaluation. The statistical analysis will be performed automatically by the computer, which will be convenient for students to inquiry about, print, count and analyze their marks.Many up-to-date technologies have been employed in this system, such as HTML, ASP, component, COM and Active X. The whole system will be managed and sent by Web Server in a unified way. The user can apply to the Server in HTTP agreement with the explorer and receive and display the web information provided by Server. The system can organize the test paper, give the examination and evaluate the test paper on line. It can also analyze the grades, inquiry about the grades and the information of the candidates and maintain the system.This paper first introduces the present situation of the ways of testing and its development, and on the requirements of all kinds of tests, this paper puts forward the general test system based on Web and further analyzes and discusses its possibility of realization, its reliability, its efficiency and ways of realization. Further more, this paper puts forward some ideas to improve and perfect the system and its operating security. At last ,through the application of this testing system, this paper comes to the conclusion that ti will improve the working efficiency greatly.
