Application Research Of Analogy And Equivalent Method In High School Physics

In high school physics,students often experience problems of confusion about concepts and models as well as the unfamiliar physical process analysis.In the actual teaching,whether in the new lesson or exercise explanation,the teachers pay more attention to the teaching of the knowledge,while the interpretation of the research method is ignored.In this paper,the application of analogy method and equivalent method in the physics of high school is listed in detail.The purpose of this paper is to reduce the difficulty of the students' study,understand the physical knowledge,develop the ability of independent analysis and thinking,and even to make the teaching more relaxing.In this paper,the application of the analogy and equivalent methods in high school physic textbooks is summarized,which are in compulsory book one and two,elective book 3-1,3-2,3-3,and3-5.The analogy method is classified into the new and old knowledge analogies,covariant,symmetric and model analogies.The role of the analogy method can be listed as follows: 1.It can find new problems and explore new laws;2.It can help understand the abstract concept and rules better;3.It also can solve complex problems.The equivalent method also can be classified into concept,motion,model and circuit equivalent.The equivalent idea can make a very complex model simpler and more familiar.You can use scenarios to study methods,Firstly,process analysis is carried out for a strange or complex situation,and the essential characteristics can be grasped,while the secondary characteristics can be ignored.then look for familiar or simple situations with the same essential characteristics,By comparing the two,we can transfer the method or rule to the past,Finally,we use the regular formula to solve the problem.Take the typical example as a carrier,this paper points out the common improper thinking from students and gives the way fore correct answers.Taking the October test of Kai Xian experimental middle school in Chongqing as an example,this paper analyzes the students' mastery of analogy and imitation methods..The results show that students have a basic grasp of the equivalent decomposition of movement,and a good grasp of simple and familiar ones,such as the problem of boat crossing a river.But the analysis of problems is easy to be fixed,Can't analyze problems from multiple perspectives;The mastery of analogies and imitations may remain superficial and require more practice to improve the depth and difficulty of the problem.
