The Design And Implementation Of Online Examination Management And Analyse System Based On Digital Campus Platform

Since the Ministry of education proposed ten years development plan of education informatization (2011-2020), the education informatization in our country has been developing rapidly. More and more schools have digital campus platform. But exam is an important part of the campus job, the online examination system is rarely included in the existing digital campus platform. Paper examination is not only time consuming and consuming resources, but also the examination questions can only be displayed in words and pictures, which greatly limits the form of examination. Especially for higher vocational and technical colleges, their courses are more technical and practical, which makes the traditional paper-based exam very difficult to inspect students’ level of professional skill. In addition, the data visualization technology is becoming more and more powerful in recent years, so the construction of an online examination management and analysis system with advanced technology will make a great contribution to the campus information.The system uses advanced design concepts, combined with many ohter systems in digital campus platform like the Base Information Management system, Educational Administration Management system and so on. This system carried out all-round and whole process management of the examination of teachers. And it makes the management of exams more efficient and fast,also the examination status can be traced to view.The examination process in this system is fully fit the school norms,and also hase a features of online interactive test mode. The system also provides a wealth of visual statistical analysis means, so teachers can get valuable information from the online test data.This system uses the unified process software development method. In this paper, the system used.NET Microsoft technology platform architecture, combining with three tier architecture technology and.NET MVC5 open source framework technology. The system adopts the architectures mode of B/S. The front end of the system mainly uses the Bootstrap open source framework technology, and the statistical analysis using the interactive graphical user interface data visualization tools Baidu Echarts as the main implementation technology. The digital campus platform contains many systems, so the single sign on technology is used in the whole platform. The system uses Microsoft’s Passport single sign on protocol as the single sign on solution. System’s database is the MySQL database.The system adopts the data cache technology and message queue to improve the performance of exam online and the amount of concurrency.The system has been deployed in the digital campus platform of Weihai Technician college, Linyi technician college and other Vocational Colleges.The system operation stability at present.The use of online examination management and analysis system makes kinds of exam data visible, and plays a great role in the supervision of teachers and students.The system can also improve the level of school management.
