Abstract

The computer web technology applying to the field of education has gone through three stages:paper examination, computer-aid examination and web-based examination. Web-based examination system can take advantage of the internet fully in practice. The established high efficient test data bank shared in common reduced running cost, breaking out of limitation of time and space. In addition, the test evaluation is more accurate and objective. Web technology makes it possible to select test topics, organize test papers and grade score automatically so that teachers can work out from the traditional tests. As a result, the test is more objective, true and comprehensive to check and improve the quality of teaching.This paper displayed an overall structure and functional modules, through a system structure design, graphic design and front-end development, based on B/S multi-storey structure to ASP and SQL-based database. The system has the following features: student management, teacher management, test management, making paper, online exam, the computer automatically scores the paper and so on.In methods, the connection between the webpage and data base is made through the usage of ADO and ASP components. The functions of student login and user login are achieved through the word matching method. The automatic online scoring system and online examination system is achieved through C# and SQL language.This paper gave a statement about online examination system design, which is based on the B/S multi-layer structure. Due to limited space, the main topic is focusing on solving major and difficult questions involved in the development process. Furthermore, the paper concluded advantages and weaknesses of the system and predict the development and application in the future. The system has five major characteristics. Firstly, test paper digitization. Inputting the test questions into computer, therefore we operate the test bank through database technology in order to achieving preservation, classification, retrieval and production of papers. Secondly, test papers are automatically generated by computer. Questions are drawn in accordance with the teacher’s paper-generated strategy. So the efficiency and quality of the paper would be improved. Thirdly, updating test bank timely. Teachers add, delete, modify, update, and enhance the vitality of the test bank based on examination results of the assessment, analysis and object of examinations. Fourthly, preserving test data effectively. Examination paper, examinations results are all saved in the database to facilitate examination papers generation, to improve the accuracy of grading, and examination standardized. The fifth topic is about security control. Authentication is necessary to edit, modify, and query test paper.The design of the on-line test systems in the paper has good scalability feature and easy to maintain and operate, etc, which would meet the current demand for on-line examination potentially.
