The Application Research Of "Mathematics Class Stack" Micro-lesson In The Township Grade Three Students' Review After Class

During the COVID-19 epidemic in 2020,terms such as "micro-class","classroom in the air" and "online teaching" became familiar to the public,and teachers became "anchors" one after another.This series of changes gave birth to the rapid development of "Internet +Education".In March 2021,the Ministry of Education pointed out in the Opinions on Strongly Strengthening the Construction and Application of Online Education Teaching Resources in Primary and Secondary Schools that: "Make overall use of network and TV channels to promote resource sharing and complement each other to cover all students." The application of teaching resources to help students learn has been supported by the state.According to the survey,the third-grade students in the township have formed a certain understanding of the after-class review of mathematics,but it is still not enough.The traditional review method can hardly help the vast majority of students to review efficiently.For middle school students and students with difficulty in learning,no guidance and weak acceptance ability make it difficult to solve the problems in time.As the product of the integration of information technology into mathematics teaching,micro class is short,concise,targeted and so on.It is an effective way for students to review mathematics after class.This study takes two classes of a township junior high school as the research object.Through questionnaire survey,teaching experiment,interview and other methods,this study explores the application effect of micro lessons on the platform of "Math Class Stack" in the township junior high school students' after-class review.This paper mainly includes two aspects:In terms of theoretical research,combined with the existing literature results and personal teaching experience summary,this paper explores the three strategies of micro-class mathematics in after-class review :(1)Return to the textbook,deeply combine the micro-class with the textbook to consolidate the basic knowledge;(2)Build system,in-depth integration of map and micro-course,and develop core literacy;(3)Group cooperation,the deep integration of cooperation and micro-class,to promote the "three meetings".Through the deep integration of micro lesson and harmony cooperation,the practical effect of mathematics micro lesson in after-class review is explored by returning to textbooks,building systems and group cooperation.In terms of experimental research,the method of combining teaching experimental research with investigation and interview is mainly adopted,which is divided into experimental class and control class.Students in the experimental class review through micro mathematics class,while students in the control class review through traditional review methods.The following conclusions are obtained by using experimental method,interview method and questionnaire method:(1)The micro-course of "Mathematics Class Stack" platform can effectively improve the math review effect of most students;(2)The micro-lessons on the "Mathematics Class Stack" platform can improve the review efficiency of most students;(3)The micro-courses on the "Mathematics Course Stack" platform can stimulate the learning interest of most students.
