Research And Implementation Of The Examination System Based On Web Technology

The rapid development of the network of education have a profound impact on e-campus, the network has not an unfamiliar term. How to use the network for education, has become a topic of concern. Network Test System in the past few years with the rapid development of computer network technology and the emerging field of study, it has both traditional and computer data bank system the same on the one hand, has its own character. Use system, learners can break with traditional educational methods and educational resources to limitations of time and space are not bound by such conditions, in accordance with their level of knowledge and time conditions for the examination. Teachers and management staff can also achieve examination of the work flow processing tasks, and is able to candidates, the study results for analysis and dynamic tracking.This article embarked from the intelligent examination actual demand, has analyzed intelligent examination system model based on the WEB, and gave a detailed elaboration on the main function of the intelligent examination system. Through to the intelligent examination system core question - - exam paper generating algorithm key research, proposed carries on the auto generating exam paper based on the genetic algorithm. To solve the problem of"Premature convergence"in view of the genetic algorithm, proposed the introduction of partial hill climbing method as well as the dynamic parameter auto-adapted adjustment method, and gave the appropriate encoding method and the hereditary operators according to the characteristic of auto exam paper generating work.In this foundation, take the Zibo Vocational Colleges adult education institute distance learning project as the background, uses B/S pattern, based on the J2EE platform in multi-layered model, the utilization current popular JSP technology and the Oracle database, has realized an intelligent examination system. And used based on the signal-to-noise ratio teaching evaluation model has realized the intelligent examination system important constituent - - examination evaluation function.
