The Design And Implementation Of The On-line Testing System

With the development of computer network technique and network education, the traditional test form cannot meet the needs of modern development. Therefore, little by little, the traditional test is replaced by the on-line test. The computer on-line test makes use of network to achieve on-line test organization, testing, grading and so on so as to separate teaching from testing, to a degree, which reduces human factors and the workload of teachers. The design and implementation of the on-line testing system is based on the above purposes.The system adopts B/S framework and has used a reasonable structure design according to the traditional testing process including the modules of identification, on-line testing, achievement inquiry, the statistical analysis of students'achievements, the formation of test papers, the automatic evaluation of test papers, teachers'statistical analysis as well as information issue. It has the functions of registration identification, test sampling according to the test types at random, grading by time and various ways of statistics and inquiry so as to satisfy the routine requirements and the guidance at the preliminary design stage.First of all, the thesis gives a brief outline of the overall demand, the operating principle and the system composition and the...
