Examination is the necessary section of the teaching; it plays an important role of orientation and feedback. To satisfy the long life, comprehensive and phrasal advanced medical education, our research which is based on the task of Gansu TCM college's teaching reform designs the online examination system based on web technology and makes it realized.This research based on the background, present situation and the development trend of network examination system, the system adopted B/W/D of three-layer structure, and expounded Asp.net, ADO.NET, XML, Ajax technology and database technology which is adopted in the system development. This paper analyzed forward the exam system functional requirements, operation process, and designed system model, identified a strategy of making examination papers and completed the database structure design based on the related theoretical research.Ajax was applied for the entire examination system in the design and development. The efficiency and performance of the test was improved by Ajax technology featuring asynchronous interaction model, JavaScript, XMLHttpRequest object and XML and the application package, especially the countdown, the page of interaction has a perfect performance. Finally we developed the examination systems for more subjects and different grades. It achieved the course management, test management, paper development, marked with automatic and manual graders, online inquiry, test result analysis and other functions. Thus, it meets the demand which is a reform of Gansu college of TCM, and builds an open, efficient communication and management platform for teachers, students and managers. Finally, this paper describes how to improve the system security measures and makes further thought for the system disadvantage. |
