| With the rapid development of mobile Internet technology,it is gradually changing the way people live,work and learn.In the field of education,there is a teaching mode of online learning using mobile Internet technology.Online education breaks the constraints of fixed place,fixed way and fixed ti me in traditional teaching mode,provides a convenient learning platform for students to adapt to the development requirements of the new era,and becomes a new way to spread educational resources.The research content of this paper is derived from the follow-up research content of the project "research and demonstration application of key technologies in Tibetan/Chinese distance education" of the national science and technology support program of Northwest Minzu University.The teaching resources in the online classroom applet are completed by relying on the course resources constructed by "research and demonstration application of key technologies of Tibetan/C hinese distance education",implement the Tibetan-Chinese bilingual online learning system based on WeChat platform.The main work of this paper includes: combing and integrating relevant resources of Tibetan distance education network,and absorbing high-quality teaching resources for online classroom system.Review and analyze the background of the topic selection of the online classroom system,the research status at home and abroad,and summarize the purpose and significance of the topic selection;the development language,Mini Program components,Mini Program API,development tools and other related technologies are explained;start from the feasibility analysis,environmental demand,functional demand,performance demand four aspects of the online classroom system demand analysis,design the system development environment configuration,the overall function and its performance;analyze the logical structure of the system,design the overall structure of the system from the three parts of WeChat terminal,WeChat API interface and server,start from the three roles of student,teacher and system administrator,design the functional structure of each role and the connection between functional modules,and realize the overall functional design of the system;In the system implementation stage,I successfully registered the Mini Program developer account AppID,built the development environment by combining the Mini Program development tools,development components and API provided by WeChat official,implemented the page layout design with HTML+CSS technology,and completed the display sequence of Mini Program pages with json technology to realize the front-end page display of the system.Use JS technology to complete main function events and realize the interaction between customers and the system,using PHP technology to complete the request from the WeChat client,connect to the server PHP configuration file,retrieve the corresponding event action,respond to the client request feedback,realize the role functions of students,teachers,system administrators,for the video playback module,video functions such as playback,download and upload are implemented by using video control,streaming media playback plug-in,media control API and AV decoding technology provided by WeChat,finally realized has the login,the streaming media broadcast,the keyword search,the on-line discussion,the topic study,the announcement notice,the video release,the information maintenance and so on many functions on-line classroom Mini Program;finally,the system is tested,the test environment is built,the test scheme is developed,the test results are evaluated and analyzed,and the system is put into operation to meet the functional requirements and performance requirements of the standard software design to ensure the normal use for users. |
