| The mechanics learning part of high school physics is the beginning and foundation for students to study high school physics,and the learning content of this part is relatively abstract for students and difficult to understand.The knowledge learning of the mechanics part will have an extremely important influence on the later learning of other physics knowledge,so the foundation of mechanics learning is particularly important.In recent years,scholars from all over the world have carried out related researches on the problems of high school physical mechanics learning and students’ learning difficulties,and they also attach great importance to them.In response to specific physics education problems,there have been continuous improvements and upgrades.At the same time,new teaching strategies have been proposed to improve the past physics teaching problems.It is hoped that this way will improve the scientific literacy of students.Mechanics,as a basic part of physics,is the key content of high school physics learning stage,and it is also the main part of students’ learning difficulties.At the same time,the learning of mechanics is permeated with many important thinking modes.According to the current high school students’ learning situation in the mechanics part,finding out the causes of learning difficulties and making effective changes will help improve the quality of physics teaching in the future.Therefore,this article takes the students’ difficulties in learning mechanics as a starting point,and discusses the main influencing factors of students’ difficulties in learning mechanics.This paper uses literature method,questionnaire survey method and interview method to carry out specific research.In this study,it is believed that the main difficulties in mechanics learning are caused by the following five reasons: 1.It is difficult to adapt to the knowledge gap between junior and senior high schools,and the formula is complicated.2.The vector concept and mathematics is weak.3.Physical concept is rigid and physical modeling ability is weak.4.Force analysis is difficult.5.The inability to relate mechanical models to life.These main factors lead to students’ mechanical learning difficulties,but also lead to students in the process of learning new knowledge,the construction of the knowledge system.Under the guidance of relevant research theories and basic definitions,this paper puts forward the following teaching strategies to improve teaching quality: 1.In high school physics class,the introduction of life situation 2.Construction of physical model,independent derivation of formula 3.Experimenting mechanics knowledge and using mathematical tools to solve physical problems.4.design experimental exercises carefully and cultivate the ability of exploration.Mechanics is the premise of learning physics,but also the key point of learning physics.Therefore,in the teaching process,the teaching content of mechanics will be related to students’ understanding of the nature of physics.Mechanics is an abstract subject,students must have high strain thinking and abstract ability in the learning process.Students must construct reasonable learning methods according to their own characteristics and knowledge framework,in order to improve their adaptability,and get out of the inherent thinking definition.Finally,using teaching practice to improve the strategies.The practical teaching results show that the four teaching strategies put forward in this paper which are feasible,operational and scientific. |
