Design And Implementation Of Online Examination System

The enormous influence of computer networks and information technology hasbrought new opportunities for education. The growing popularity of network more andmore attention has been paid to carry out education and teaching, online teachingtechnology into daily teaching, traditional examination methods are bound to facechallenges, network online exam will serve as an important part of the online teaching,has become one of the hot skills within the application.Network test system based on Web technology by means of the characteristics ofthe network, greatly expand the flexibility and real-time of the examination; theadoption of a large number of standardized questions, you can use the computer gradersgreatly improve the efficiency of marking; more accurate results statistical analysis ofthe examination can be reflectedresults. Network Examination System can save the testcost, long-distance synchronization examination, and improve test efficiency and ensurethat examination results of a fair, scientific, and timely aspects of practical significance.This system on the basis of the analysis of research on the status quo of the currentnetwork of Educational Testing platform, combined with the actual school teachingneeds by comparing the two main types of architecture, the online examination systembased on B/S structure. The system has a complete examination and managementfunctions, to achieve the following main function modules: teachers, students canmanage users in different roles, given different permissions; proposition teachers caninput questions, modifying; invigilating teacher can monitor real time test processmanagement; allows a certain number of candidates under the environment of networkexam system, automatically discriminating examination time and volume; system willbe set according to the algorithm of examination paper, examination after the end of theobjective test automatic scoring, the results are given. Test strategy is one of the keycontents of the online examination system, the system is based on database informationof multiple constrained random test paper strategy, through improved random questionstrategies to ensure that papers real effect.This system describes the system requirements and the overall structure and process to explore the key technologies involved, and module design andimplementation of specific elaboration.
