Design And Implementation Of College Mobile Learning Platform Based On Wechat Public Account

In the 21 st century,the mobile Internet from 3G to the 5G being developed is also rapidly emerging at a speed that is amazing to the world.The speed of the mobile Internet is no longer lost to the cable network;at the same time,the rapid iteration of smart terminals,the price drop,and the government'downward adjustment of communication tariffs has enabled smart terminals,especially smart phones,to quickly enter everybody's daily life.This situation in turn has promoted tremendous changes in the overall Internet landscape.The rapid development of the Internet has had a profound impact on the world.The education sector is no exception.Many digital learning products have been produced.The typical e-learning platform,such as Blackboard,has been widely used in universities around the world.M-learning(mobile learning)was born in the context of this era.The concept of mobile learning began in the United States at the end of the last century.In China,the concept of m-learning was first introduced to the country by the Irish distance educator Desmond Keegan.But so far,m-learning still has no recognized and clear concept.Desmond proposed in his paper "From D-Learning(Distance Learning)to E-Learning(Electronic Learning)to M-Learning(Mobile Learning)" that the three stages of distance education are d-learning,e-learning and m-learning.m-learning can be simply summarized as wireless communication technologies such as Bluetooth,mobile communication networks,and WIFI,enabling people to use smaller and more convenient devices to conduct learning activities anytime and anywhere.At present,in China,the e-learning product is dominant in the market.After nearly 20 years of research,m-learning has produced a lot of results.There are also many mobile learning products on the market,but most of them are language learning,preschool education and other products,and fewer products are directly applied to the campus.Based on this,combined with the theory of mobile learning,this paper designs and implements a mobile learning platform based on wechat public account.The main functional modules of the m-learning platform are as follows:1.Teaching Information Management Module,the main function is to query all kinds of teaching information,including teachers,students,classrooms,class schedules,exams and other information.2.Course learning management and discussion module,the main functions include student attendance,course video live and on-demand,course resource download,teaching information notification,learning discussion.3.Teaching data statistical analysis module,the main function is to monitor and collect statistics of students' learning,including student online time,learning time,attendance and so on.Considering that wechat has the advantages of large flow,convenient,fast,stable service and powerful functions,this paper chooses wechat public account as the system implementation carrier.JFinal is a free and open source Java Web MVC framework designed by Zhan Bo,an excellent software engineer in China.Its most important feature is that it is small and fast,and it fits the requirements of the mobile learning platform.In addition,JFinal also integrated the WeChat public account development technology,and developed the JFinal-based WeChat public account development SDK-JFinal Weixin,which greatly improved the development rate of the WeChat public number.In addition,this article also uses streaming media technology to achieve live video of the course,multiple use of timed task technology to achieve notification and other functions.In summary,this article uses Linux + Apache Tomcat + Nginx-rtmp + MySQL + JFinal as the basic technology architecture,and basically implements the mobile learning platform.
