Research On Construction And Application Of Blended Learning Mode Based On WeChat Public Platform

With the rapid development of the information age,new technologies such as education data,cloud computing,learning analysis,data mining and deep learning are applied in the field of education to promote the modernization of teaching mode and meet the teaching needs of teachers and students.Teachers adjust teaching plans in time to ensure that teaching is centered around students,so as to improve the teaching effect.However,many practical courses in Colleges and universities still exist such problems as a large number of students,limited teaching hours,inadequate experimental equipment,less interaction between teachers and students,poor self-learning of students.Traditional classroom teaching pays attention to teachers' teaching and neglects students' feedback.Pre-class and after-class learning are completely disconnected from classroom teaching,and students' learning outside the classroom lacks teachers' guidance and monitoring.Blended learning,which combines the advantages of traditional classroom and online learning,can organically combine the three stages of pre-class,mid-class and post-class.The Wechat Public Platform has become a bridge of communication between teachers and students with the advantages of convenient use and strong interaction,so that the interaction between teachers and students is no longer confined to the classroom,so that students' learning is not only carried out in the classroom.On this basis,this study attempts to construct a blended learning model based on Wechat public platform in order to solve the problems existing in traditional practical courses.The main research contents include the following aspects:(1)Reading a large number of documents related to hybrid learning and Wechat public platform,combing the development status of hybrid learning at home and abroad and the application status of Wechat public platform in the field of education.This paper summarizes the definition and characteristics of blended learning,the definition of blended learning mode,the existing blended learning mode,and the applicationadvantages of Wechat Public Platform,which provides a theoretical basis for the construction of the latter mode.(2)Based on the analysis of the existing mature blended learning model,according to the practical needs and combined with the functional characteristics of Wechat public platform,a blended learning model based on Wechat public platform is constructed.The model consists of three stages: front-end analysis,activity and resource design,and teaching evaluation.The paper elaborates the components of each stage in detail.(3)On the basis of front-end analysis(learner characteristics analysis,learning object analysis,learning environment analysis),this paper chooses the course "Photography Technology" to apply the blended learning mode based on Wechat public platform,designs the mixed learning activities and develops resources for this course,and develops the blended learning based on Wechat public platform from three stages:pre-class preview,classroom teaching and after-class review.Finally,the validity of the model is verified by the evaluation of students' process,curriculum assessment and teaching effect.Practice results show that blended learning model based on Wechat public platform can effectively promote the interaction between teachers and students,and play a positive role in promoting students' learning.(4)Summarize the research results,analyze the shortcomings and limitations,and put forward the research prospects.The research prospects is to strengthen the learning of blended learning theory knowledge and the development technology learning of Wechat public platform,in order to further improve the blended learning model based on Wechat public platform,so that it can be applied to more practical courses.
