The Design And Practice Of Micro Physics Course In Junior Middle School Based On "Unconventional" Experiments

Although the content of physics in junior middle school is simple,for students,they still need to present concrete and intuitive phenomena in front of their eyes,so that students can have a deep impression of experimental phenomena,and then more firmly grasp the principles of physics.Compared with the traditional physics experiment in the laboratory,"unconventional" physics experiment is closer to students' life.By carrying out the "unconventional" physics experiment teaching,we can make the physical phenomena present in front of students intuitively and truly,so that students realize that physics comes from life,and life can not be separated from physics.With the rapid development of information technology,great changes have taken place in the education industry.The promotion of digital education makes the teaching and learning resources of teachers and students more abundant.In the field of education and teaching,as a kind of digital learning resources,the application of micro-courses is increasing day by day,which brings great convenience to the cause of education.Referring to the Compulsory Education Physics Curriculum Standard(2011edition)and the eighth grade physics textbook of the People's Education Press,this paper designs the "unconventional" physics experiment with students as the main part.Considering the shortage of some physics experiment resources in the current teaching,taking micro-class as the carrier of experiment teaching,selecting some "unconventional" physics experiments that are not easy to operate in class,this paper designs the junior middle school physics micro-course based on the "unconventional" experiment,and studies the effect of physics experiment teaching.Specifically,this paper mainly studies the subject from the following aspects:Through reading a large number of documents,we can understand theresearch status of "unconventional" physics experiment and micro-course,and then determine the feasibility of the design of junior high school physics micro-course based on "unconventional" experiment.Understand the connotation,constituent elements and theoretical basis of "unconventional" physics experiment and microteaching,and theoretically analyze the concepts related to them.The design principles and steps of physics micro-course are discussed theoretically.Practical research.Firstly,through interviews and questionnaires to understand the current students' understanding of micro-course and "unconventional" physics experiment,understand the implementation of "unconventional" physics experiment and the use of micro-course in junior high school physics classroom;secondly,according to the teaching needs,design and record the junior middle school physics micro-class based on "unconventional" experiment,and use the field test method for classroom teaching according to the experimental class and control class provided by the practical school.Thirdly,in order to facilitate students' to learn at any time and make full use of experimental resources,a public platform of WeChat is built,and some micro-lessons are saved on the platform after being put into use and modified and improved.This study believes that the "unconventional" physical experiments that are not easy to operate in class can be demonstrated in the form of micro class,so that students can understand the connotation of the experiment concretely and vividly."Unconventional" physics experiments with students as the main part can save experimental resources and realize the reuse of experimental resources,and "unconventional" physics experiments with students as the main part can greatly improve students' attention in the classroom and help students form scientific literacy.In practical teaching,this subject can achieve good teaching effect.
