Online Examination System Based On Web-design And Realization

In recent years, as a result of the swift development of the Internet technology, the distance learning education model and the test pattern has all had the qualitative leap forward. Especially nowadays, with the gradual development in the modern distance learning education educational model, the test pattern reform becomes a must. The research and developing of online network test system has become the core part of the modern distance learning test pattern reform.The present paper mainly researches into online test system function skeleton and some key technologies involved in the realization process, and have designed "VB the programming" curriculum as the test subject, based on Web online test system. This system constitutes of the system administration, the educational administration management, the teacher's proposition, the students' taking a test, that is, there are four big module constitutions. The manager enters the administration module, responsible for the system establishment and the user management and so on. After the administration personnel registers, they are responsible for educational administration management operations, examination paper management, result management and so on. The teacher registers are responsible for the test question input, the examination paper comments and so on; The student registers can get test, consult results.In order to guarantee the online test usability and fairness, the system dwells on examine two big function modules: the automatic group volume and the subjective topic to make the research which can satisfy the actual test application demand. Uses the spatial vector modeling in the automatic group volume function to make a adjustment to the stochastic examination paper and the standard examination paper, which will minimize the difference of the knowledge coverage and the overall difficulty coefficient when pulling out the topic composition stochastically from the examination papers; The VB procedure is also used in the Examining of test papers of the subjective topic and to compare its similarity with the standard procedure structure, in which the spatial vector modeling makes contrasts, and give marks to the paper according to the similarity of the program.
