The Application Of Physical Model In Physics Teaching In Senior Middle School

Physics is a subject that studies the laws of motion of objects and the basic structure of matter in nature.The natural phenomena encountered in practice are often complex,and if we want to study the complex phenomena accurately,we need to break them down into simple models.Therefore,in studying some physical problems,modeling is the most direct,effective and universal way to solve them.First of all,it is necessary to simplify,summarize and summarize the phenomena to be studied in nature according to the problems studied,so as to obtain the problem model related to the research problems,and secondly,to analyze and derive the logical reasoning by mathematical methods.Finally,the physical law of phenomenon expression and the physical reason of phenomenon formation are obtained.In the classroom of physics teaching in high school,the practical problem that will need to be solved is modeled,and the way of thinking that guides students to build a model to solve problems can help students to solve problems after encountering complex problems.This paper collates and analyzes the literature on model teaching at home and abroad,summarizes the theoretical achievements of using physics models for classroom teaching,and analyzes the shortcomings of the current research situation.Starting from the point of view of psychology and pedagoagocy,the general teaching mode of applied physics model for classroom teaching and the design principle of feedback exercises after classroom teaching are obtained.This paper first summarizes and summarizes the mechanics models encountered in the teaching materials,discusses the characteristics and laws of these mechanic models,and makes it easy for teachers to choose suitable models for effective teaching.Secondly,we choose the summed-up mechanics model,design reasonable teaching examples,and apply them in the actual classroom teaching.In the actual classroom teaching,pay attention to the teaching methods of students as the main body,set up problem guidance and help students to establish a reasonable physical model,and establish the physical model analysis and demonstration,discuss the scope of application of the model,and finally set up classroom exercises to test the learning effect of students,classroom exercises should have the characteristics of students prone to errors and confusing understanding.Again,select classes with different levels of learning ability for classroom teaching,and group students,two groups of students under the same level of learning ability,respectively,use the traditional way of teaching and applied physics model teaching,through the same feedback exercises to test the effectiveness of applied physics model classroom teaching.Finally,through the analysis,it is concluded that the classroom teaching method of applying the model to teach is the best effect on the students with the secondary learning ability level.Compared with students with good learning ability,students with secondary learning ability level rely more on the teacher's classroom explanation,and simple and clear explanation can effectively improve the learning effect of middle school students.The strategy of applying physics model to classroom teaching and the setting of afterschool feedback exercises are of certain feasibility and practical significance.In view of the problem of how to model teaching in high school physics teaching,some suggestions and methods are put forward.Through this kind of classroom teaching method,we can help students form the consciousness of simplifying complex problems according to the problems studied,establish physical models to solve practical problems,improve students' ability to solve problems by applying physical models,develop students' scientific thinking quality,and help students in the development of physics later.
