Design And Implementation Of Online Test Paper Generation System

In recent years, with the rise of the "Internet +" mode, innovative changes are happening in the social from all walks of life, including new forms of "Internet+ education" having a huge impact on the traditional education. Teaching activities around the Internet platform, this way has greatly expanded the students access to the learning resources, to cultivate students’use of fragmented time the habit of learning. The rapid development of online education, promote the reform of education contents, teaching means, make modern education more fair, more efficient. In this education mode at the same time, also the examination of the teaching method is put forward innovative requirements. Because online generating test paper as a core part of the online exam, the quality of its service generating test paper largely determines the level of online examination.On this background, the paper study the key questions of how to generate test paper and how to control exposure. Online generating test paper system can provide humane services to ensure the quality of the paper as much as possible, to reduce the workload of teachers, improving teaching efficiency.In this paper, the classical test theory, to explore the questions reasonable indicator system, combined with manual test paper, intelligent test paper, test paper three kinds of papers share the advantages of model test paper, test paper proposes humane mode, improve the user experience, and object-oriented method of business processes and functional requirements of the online test paper system were analyzed. On this basis, given the detailed design and database design, system architecture, an important module.Papers segmented genetic algorithm selection strategies, giving priority to the kinds of questions and the corresponding number of questions bound to achieve a soft segment color body weight to build fitness function of the degree of difficulty and comprehensive knowledge of high-quality papers coverage constraint evaluation and paper exposure control method is put forward and use JACOB technical papers generated Word version, expanding the line online paper system examinations.Finally, according to the design, the use of SPRING, HIBERNATE, AJAX and other technologies to achieve the development of an online generating test paper system. Analysis of the result showed the method having satisfied the test paper constraints effectively, and reduced paper exposure rate.
