| The traditional test method is subject to time and location constraints, large-scale processing requires a lot of manpower and material resources and less flexibility. With the progressive development of network technology, use of network and computer technology to change the traditional way is a choice test, which the network change practice test exam to become an important content. Web-based technology by means of the network test system can be carried around the world Internet, it place restrictions on free examination, greatly expanding the flexibility of the exam. Paper content generated from the item bank in immediately, and the use of a large number of standardized paper-only benefits the fairness test, reducing the occurrence of the phenomenon of plagiarism, but also greatly improved the efficiency of scoring, but also directly on the test results effectively statistical analysis, reduce the intensity of the related work of teachers, but also conducive to a full analysis of the problem in order to achieve the objective to test and promote religion. Therefore, the use of network test approach will be the future trend test.Network online examination system has a lower test cost, to solve the examining work of heavy advantage. It can remove a lot of Linkao teachers working paper can immediately generate the contents of the item bank; teachers do not need to do after the test scoring, statistics, analysis, computer automatic grading can be directly sent to the database for the results statistics, summary sort. Paperless examination, greatly improve the work efficiency, while random Zucheng papers, and there is no leak examination papers and examination cheating problems, to make examination of the Gong Ping Xing, the answer's Anquan of effectively guaranteed.Today the world for remote examination system based on Internet research and development work carried out is not very long, but based on web technology to build the online examination system has become the mainstream of development. Database security, sharing, data transmission security, access control, identification technology is built test system issues to consider. At present, some distance education institutions have developed online examination system, the basic realization of Internet-based B / S structure of online examinations. Server-side through the dynamic generation of the background papers and the item bank of test questions for standardized real-time assessment of results. But compared with the traditional paper-based exams, online tests are based on current standardized tests and generally can only be used for non-formal examinations, because for many considerations of not a perfect system, and thus to make the online exam in the near end time is difficult to completely replace the traditional examination.Currently, Web-based exam is primarily for the training of community and distance education exam examination. A successful examination based on WEB, need a good network environment, a good test platform and a good question bank. But a real intelligent WEB-based examination system implementation is a complex process, the examination item bank research platform and to rely on software development experts, subject experts and proficiency examinations tested the theory and the cooperation of the three propositions of the experts. Online examination system includes two kinds of typical implementation technology. One is the traditional client / server (C / S)-based MIS-type structure, server-side save the questions, the test machine when the client needs to test the application and install the appropriate client-side database configuration, because every time examinations have on the environment, the initialization process, and thus more cumbersome examining work; and examination process on the client, the security has been a certain extent. Another test system using Web technology, using the user interface layer / tier / database layer three-tier architecture, with a better security.According to the development of this online examination system and the preparation, the same system to local area network as a platform and INTERNET technology combine to make the students through the WEB browser to the online course exam, the teacher can edit the Exam Database, information maintenance and test paper work. The system is mainly used in semi-open type and tissue type, tissue type is a class as a unit, the teacher time designated for the designated examination room. Semi-open means that students can be in the school room, this place is remote login to other machines, do not choose to enter the examination system locations.This paper analyzes the network line test system development, then the actual teacher of teachers starting business, designed and developed a Web-based online examination system network environment. The network-line examination system will provide a scientific and educational management system and reasonable test management solutions, improve the efficiency of test administration, the full realization of paperless office. In the system design and development process, using the object-oriented and modular design school examinations for the features and functions of the system requirements to make overall planning of the system so that the whole system flow clear, logical and reasonable. Network online examination system is mainly to achieve a student log, student registration, online examinations, query results, course title management, and public notices setting modules.The system uses the current popular ASP technology, application of the current popular AJAX technology, based on B / S application architecture to achieve the business logic, front page and the data storage layer separation. Any level of change will not affect the other two, making the system more robust and flexible, able to adapt to the changing and development of the system. System to support the client as the basic browser, users can conduct tests in real time through the network management. The system user friendly interface, the module clear, simple, easy to use, could be easily understood, a study would, general performance is good, practical, easy to spread.The system will provide senior managers with more efficient, thoughtful service and the timely and accurate information to provide more help for the test administration, enhance the management level, and comprehensively improve the work efficiency of marking examination papers. |
