Research On Construction Of Concepts Of Movement And Interaction In Senior Middle School Physics

Physical concept is an important part of the core literacy of physics,affecting our thinking and way of physical problems,and our attitude towards the physics world.This thesis introduces the connotation of physics concept and expounds the infiltration and evaluation of physics concept in teaching in the physics curriculum standard of senior high school.The curriculum standard does not give exact practical opinions and evaluation criteria for the concept of movement and interaction in physical concepts,so this thesis takes the concept of movement and interaction as the research object to further implement the infiltration of physical concepts in teaching.Based on the study of the relevant literature on the concept of movement and interaction,this paper analyzes its connotation,and divides the concept of movement and interaction into three sub-concepts: the concept of movement,the concept of interaction,and the concept of the relationship between movement and interaction.And construct the concept model of movement and interaction,which takes the concept as the first level,the sub-concept as the second level,the core concept as the third level and the related knowledge as the fourth level.And explain each sub-concept and establish the corresponding sub-concept hierarchy model.Based on this model structure,the test paper of the hierarchical model of the first compulsory volume of the people's Education Edition is designed,and the concept level of exercise and interaction is divided according to the level of physical concept.With the help of FCI,FCME and other test questions,the questionnaire is developed to improve the reliability and validity of the questionnaire.Through the survey results of the questionnaire,we have a certain understanding of the level of students' concept of movement and interaction,and have a deeper understanding of the various difficulties encountered by students in dealing with problems and the application of problem-solving methods.And in the survey guided by the hierarchical model,it is found that the main problems of students in the process of concept construction mainly lie in the understanding of the nature of concepts and laws,the grasp of core concepts and wrong cognition.Finally,the paper puts forward some teaching strategies such as strengthening concept teaching in physics teaching in senior high school,making students go through the process of inquiry,helping students to abandon their wrong cognition,helping students to form a knowledge framework,and so on,so as to improve students' concept of movement and interaction.A teaching case design based on concept construction is given.The main purpose of this study is to analyze the process of constructing the concept of movement and interaction,hoping to serve as a teaching tool.
