The design and implementation of a cross-platform teaching system

Abstract

With the development of computer technology and network technology, the traditional test mode is not able to fully meet digital, standardized test requirements. Traditional exam modes include artificial test paper, artificial marking, several processes statistics and performance analysis papers, results statistics, papers analysis etc., The whole process is cumbersome and inefficient. Moreover, with the change of examination techniques and carrier landmark, we can say the traditional examination method is no longer suitable for today’s exam. Now appears online examination system is an extension of the traditional examination and change, with its own efficient and convenient, flexible benefits, widespread concern various institutions. On the other hand, with the rapid development of mobile communication technology and intelligent portable device innovation, appearing more and more sophisticated intelligence products, marking the arrival of the mobile Internet era. As a smart phone operating system, Android platform by virtue of its open source, openness and stability, it has become the current most users, the fastest growing mobile smartphone operating system. In summary, The campus of the previous examination system is applied to the mobile client, not only can make full use of space, anytime, anywhere to exam, not too much limited by time and space. And greatly simplifies the examination process, reducing the onerous test management work, which is a mobile Internet application development model better. In order to make the examination system to have flexible scalability and cross-platform portability, At the same time convenient for each subsystem integration, based Android platform and application software technology Web application server communication, combined with the actual traditional examination process, design the overall structure and function of the system to achieve the main module, in order to develop versatility, flexibility, ease of maintenance of the mobile phone side of the school examination system. The system includes system settings, test status, clear examination, re-examination, the online exam, the student information maintenance and queries, bank maintenance, query results, review papers, exit multiple module systems, it can enter their own questions and its related the freedom to create and delete, save students answer timely information, the system uses a manual marking and automatic scoring combination to provide a more objective reference points. The system uses Android as an operating system, using J2EE as a development framework, JAVA as the system development language, using the B/S structure of the network architecture model, applicating SQL Server2005 database management system to store student information and questions as to achieve different people, from different locations (such as LAN, WAN, Internet/Intranet), with different access methods to access and manipulate a common database. It can effectively protect data platform and access management, as well as its own security server database, to better improve the overall security of the system. In this paper, based on the Android platform school examinations system design, development and related technology is described and discussed. First of all, the analysis shows that schools in the past exam mode, so as to define the overall layout of the system and its related processes. Secondly, using the JAVA language for the completion of the layout of the main module for development, implementation steps are discussed in detail. Finally, the system is optimized and the relevant contents are summarized. After the completion of the system development, the function of each function should be checked to ensure that the system can achieve the expected purpose, better guarantee the availability and safety of the system. The realization of the Android platform of school examination system, not only to meet the school standardized tests of functional requirements, and well solves the shortcoming of lack of portability of the original system. It is able to improve the flexibility and practicality of the system, teachers and students can use and search examination system related information anytime and anywhere, to a greater extent save time and space occupancy. In the implementation of the Android examination system, there are still many problems, but also need to continue planning and design. But the whole process of its development, this is a familiar and the process of exploration, and it is proved that this is an effective research and development process, at the same time,, it has important guidance and reference for the future development of a more excellent and more efficient system.
