Coping Strategies And Causes Of High School Students' Physics Dynamics Misconception

The concept of physics is a high generalization of a kind of physical phenomenon and the core of physics knowledge.The concept of physics in senior high school is more abstract and logical,so the concept teaching has become the key and difficult point of Physics Teaching in senior high school.Before and after the learning of scientific concepts,students will form incorrect misconceptions which are contrary to scientific concepts.These misconceptions are widespread,which greatly affect the effectiveness of students' physics learning and hinder the formation of students' scientific concepts.Dynamics studies the motion and force of objects,which is the cornerstone of high school physics.Newton's law of motion is the core of dynamics,and it is also a difficult point for students to easily get confused.Therefore,this research explores the concept of Newton's three laws,analyzes its causes,and puts forward the corresponding concept transformation strategies for teaching design.The author found problems in teaching,consulted materials,used literature review and theoretical research to determine the research scheme.After that,I interviewed the experienced teachers to get a preliminary understanding of the misconceptions in Newton's three laws,and changed the teaching strategies to consult them.According to the interview results and FCI measurement table,a two-stage questionnaire was developed.Take the students of Leshan No.1 middle school for example.After the analysis of the results of the questionnaire,combine with the students' wrong questions after Newton's law of motion,and sort out the students' minds before and after school to come up with the concept of Newton's three theorems.Through the analysis of the reasons for the choice in the two-stage questionnaire and the follow-up interviews with the students,the causes of the misunderstanding of Newton's law of motion are analyzed: daily life experience and observation,the lack of close integration of theory and practice in teaching,the subjectivity of teachers' teaching,the incomprehensibility of students' understanding of the knowledge in teaching,the abstraction of physics concepts in senior high school,the lack of self-awareness in teaching,and the lack of self-awareness in teaching The arrangement of teaching materials and the improper use of teaching aids.According to the students' misconceptions and the causes of their formation,this paper puts forward the corresponding teaching transformation strategies,and designs the teaching of Newton's three laws: cognitive conflict strategy,experimental teaching strategy,cognitive teaching strategy of physics history,scientific concept returning to life,analogy teaching.The effectiveness of the concept change strategy is proved by the test.
