Design And Implementation Of Online Learning System Based On Wechat Platform

With the rapid development of mobile Internet technology,mobile devices have become an indispensable information dissemination carrier in people's lives,bringing great convenience to people's life,work and study.It is the same in the field of education.The traditional education model has been difficult to meet the needs of modern education.Under this background,the”Internet Plus Education" industry model has gradually entered people's field of vision,more and more online education platforms have emerged,setting off a wave of online education.As a supplement to traditional classroom education,online education can break the barriers of traditional teaching mode,making teaching and learning no longer limited by time and space.At the same time,it can combine the superiority of various schools to share high-quality teaching resources around the world.Therefore,designing and implementing an efficient online education system makes the traditional teaching mode and online education complement each other,which is of great significance for improving the teaching quality of various schools.This paper first expounds the research background and significance of online learning system in colleges and universities based on Wechat platform,and deeply analyzes the development status of online education at home and abroad.The related knowledge and techniques involved in the system research process are introduced in detail,including mini programs,WePY framework,Vue front-end development framework,Express server-side framework,Node.js and MongoDB database.This paper analyzes the needs of online learning systems,on this basis,the goal of system is proposed,the whole framework of the system is constructed,the functional modules of the system are divided,and the database of the system is designed according to the E-R diagram,completed the design and implementation of the web-side management system and the mobile-side online learning platform.For the web-side management system,functions such as file uploading,question bank management,exam management,user management,and statistical analysis are implemented;The mobile-side online learning platform uses WeChat client as the carrier to implement login and authorization,question bank exercises,online exams,instructional videos,historical record,grade rankings,and wrong question exercises.This paper compares and analyzes the commonly used intelligent test paper method,and applies intelligent algorithm based intelligent test paper algoritihm to the test management module,teachers can set test parameters for intelligent test papers,not only improve the success rate of the test papers,save the time of the test papers,but also ensure the quality of the test papers.The system has undergone rigorous testing,and all functions have reached the design goal,which satisfies the needs of various institutions for online learning systems,enhances teaching quality,and strengthens teaching management.The research results of this paper are of great significance for the advancement of intelligent education.
