Design And Implementation Of Mobile Teaching System Based On We Chat Service

The past decade, the rapid development and high penetration of Internet and mobile communications technology,and enhance the utilization of mobile devices, instant messaging software from the PC side to the mobile terminal. Wechat as instant messaging software of the largest domestic users, because of the disadvantages of traditional teaching mode,students dependence on the mobile terminal, and entirely of their own time and space reduction and other factors for the development of mobile teaching foundation. At the same time, it also improves students’ subjective initiative in learning and the knowledge communication between teachers and students. Therefore, the development of mobile learning system based on Wechat service to promote the development of information technology education.A complete mobile teaching system is designed by the software layer and the physical layer. Among them, the software layer structure is presented to the student level front-end design and back-end design and implementation of specific tasks. Physical level structure include aspects of high responsiveness, system optimization, load balancing and so on, this paper provides the basis for the smooth operation of the system. This system is based on the We Chat open public platform interface, the design of mobile learning platform based on We Chat services. Using popularity of We Chat’s public platform to promote the development of mobile teaching.At the same time, the public platform provides standardized interface for developers to better design and expand business functions according to actual demand.The system is mainly composed of We Chat client and PC client information management system and the application server to deploy the ECS of Ali cloud platform, In the PC side, the data on the ECS for operation and maintenance and management. We Chat client is divided into knowledge and learning, teaching information and teaching feedback, students use these three modules to mobile learning. Wechat service communication system consists of data communication, message processing and message response of three parts, Data communication is responsible for message XML and JSON data format parsing and packaging, and then data communication interface with We Chat public platform; Message processing is responsible for the processing of We Chat background data, the students take theinitiative to reply to the message. PC end information management system includes import,export, function menus, charts and exit, the function menu except file Manager can be used to import and export feature to update teaching materials, the chart can show the results of the questionnaire in graphic form.First, the overall design of mobile teaching system, system requirements and system analysis role, then all sub-modules needs analysis and overall design and system performance analysis and database table design. Then, system architecture design, detailed design of the system. In this paper, the performance of the entire system optimized to achieve the results show that the system performance and functions are performed well, reaching the actual demand.
