Design And Making Of Physics Experiment Micro Lesson In Junior Middle School

With the coming of 5G era,network education is becoming more and more popular.In early 2020,COVID-19 led to the transformation from offline instruction to web-based instruction,which further highlighted the advantages of online education.In daily teaching,students are eager to learn and master knowledge more efficiently.Micro class is an effective way for students to learn knowledge quickly and efficiently.Students can strengthen their learning of weak knowledge anytime and anywhere.According to the design principles of micro lesson teaching,this paper summarizes a set of methods suitable for physics teachers to make their own experimental micro lesson.Through literature research,the author found that previous studies did not systematically teach how to design and make micro class.The author browsed a large number of micro Lecture Resources on the Internet and found that there were some problems,such as nonstandard experimental operation,wrong experimental principle,messy video interface,unreasonable picture proportion and so on.This paper summarizes the principles of micro class selection,design and making,summarizes the methods of pre recording and post editing,and designs the template of micro class production.Then three specific experimental cases are selected to explain the micro lesson production in detail.And the self-made micro class is applied to the actual teaching,which is recognized by teachers and students.This study shows that teachers can not only improve students’ experimental efficiency,but also reduce the pressure of front-line teachers.In this paper,the detailed explanation of self-made experimental micro lesson provides a reference case for the majority of front-line teachers to self-made experimental micro lesson.
