The Application Of High School Physics Micro Lesson Based On Wechat Public Platform

The WeChat public platform has the advantages of diversified methods,high information transmission rate,easy operation,timely and convenient interaction,and wide range of users.Compared with traditional classroom teaching and teaching resources,micro-lessons can transfer knowledge to students through a variety of methods such as images,sounds,and text,which is appropriate for the dissemination of knowledge in the mobile learning era.Therefore,in this research,we based on the WeChat public platform and uses micro-lesson as a carrier to study the teaching effect of assisting high school physics teaching.In this research,we mainly study the following four types of courses based on the WeChat public platform:new course teaching,topic review,answer questions,and physics popularization.Prior to practice,we can learn about the current status of courses based on WeChat public platforms in high school physics teaching,students' use of WeChat public accounts to assist physics learning,and the mainstream push content and presentation form of WeChat public accounts related to physics teaching by investigating high school physics teachers,students,and WeChat public accounts related to physics teaching.On the basis of these investigations,the teaching practice was designed in accordance with the Connectivism Learning Theory,Cognitive Load Theory,Mobile Learning Theory,Constructivist Learning Theory and basic principles of physics micro-class design in high school based on WeChat public platform.In this study,we used two classes of equivalent level in No.1 middle school of Huangzhou District as the experimental group and the control group to carry out teaching practice.The teaching practice is divided into two modules.The first module uses "Lenz's Law" as an example to study the new course teaching based on the WeChat public platform.From the comparative analysis of the experimental group and the control group,it was concluded that the effect of using the WeChat public account to assist teaching the new course of Lenz's Law is remarkable.The second module researches physics teaching in high school based on WeChat public platform from the aspects of topic review,answer questions,and physics popularization.Finally,from the questionnaire survey of the experimental group and the contrastive analysis of the control group and the experimental group,it was found that high school physics teaching based on the WeChat public platform can give the following help for students' learning:(1)Can expand students' knowledge and stimulate students' interest in physics;(2)Can help students master learning methods and understand physics knowledge;(3)Can satisfy students' personalized learning needs,and stimulate the subjective initiative of students.Finally,through the problems encountered in teaching and some ideas of colleagues and students,the following advices are given for the teaching of WeChat based on WeChat public platform in high school physics:(1)Design teaching content according to students' needs;(2)Clarify the design of the WeChat subscription column,and the navigation needs to be clear;(3)Highlight the theme of WeChat subscription,the teaching characteristics,and build a knowledge network;(4)Take full advantages of WeChat subscription and establish a good teacher-student friendship;(5)The content of WeChat subscription must be updated frequently.
