Research On The Application Of Micro-lectures On Junior High School Physics Exercises Based On Life Situations

The rapid development of Internet and technology brings a piece of vitality to the field of education.As a new teaching mode,micro-class greatly enriches teaching resources.With the help of modern educational technology,exercises are the center,which provides great help for students to study independently in their daily life.Recently,education departments across the country to prevent and control the New Coronavirus Pneumonia epidemic spread took measures to delay the beginning of school.Local education authorities encourage teachers to create and share quality teaching resources.Meanwhile,micro-classes and other online learning methods and resources are favored by teachers and students.Under the background of the New Curriculum Reform,physics teaching also pays more and more attention to test students' ability of connecting with reality and solving problems.Therefore,the micro-lesson of physics exercises in middle school also needs to further innovate the idea,starting from the social production and life.This research through the investigation to understand the teachers and students in the teaching process of the current situation and needs.It also analyzes the feasibility of the problem sets micro-lesson based on everyday context,and constructs the application model of problem sets micro-lesson based on everyday context.In this study,a series of studies were carried out on the design and application of physics exercises based on life situations by means of literature research,investigation,experiment and summary and induction.This research consists of six parts:In the first two chapters,the background,current situation and related theories of micro-lessons are sorted out.The third chapter and the fourth chapter firstly investigates the teaching methods of physics exercises in middle schools in Shenzhen city and Binzhou city.At the same time,it also analyzes the feasibility of micro-lesson based on everyday context auxiliary teaching,the function orientation of micro-lesson based on everyday context,and the relevant principles and strategies of making.And we designed a practical research on the auxiliary teaching of exercises and micro-lessons based on everyday context.The fifth chapter and the last chapter analyzes the effect of the practice of micro-class through the form of student questionnaire and test,and finds out the micro-lessons designed in this study can significantly improve the learning effect of middle and low grade students,which is conducive to shorten the distance between students' life and physics learning and make physics learning full of fun;At the same time,the author makes attribution analysis on the existing problems such as universality and effect significance,and puts forward some countermeasures,in order to provide help for the first-line teachers to develop and apply micro-lessons and students to make use of high-quality online learning resources;The last part of this paper is the prospect of future research based on the existing limitations of this research.
