A Construction Of Hierarchical Model For Concepts Of Movement And Interaction And Analysis Of High School Physics Textbooks' Adaptability To The Model

The discipline core literacy is the concentrated embodiment of the value of discipline's teaching,and is the correct value concept,essential character and key ability that students gain gradually through subject learning.The core literacy of physics includes four aspects: "Physical conception," "scientific thinking," "scientific inquiry," and "scientific attitude and responsibility."“Physical Concept” is a basic understanding of matter,movement and interaction,energy,and so on,which are formed from the perspective of physics;it is the refinement and sublimation of physical concepts and laws in the mind;it is the basis to explain natural phenomena and solve practical problems from the perspective of physics."Physical concepts" mainly include physical concepts,concepts of movement and interaction,and energy concepts.This study focuses on the physical concept of physical core literacy,taking the concepts of movement and interaction as the research object,in order to complete hierarchy model of physical concepts and hierarchy model of movement and interaction,based on the hierarchy model of movement and interaction makes adaptive analysis of high school physics textbooks.This study has a certain theoretical significance for understanding the concept of physics and the concept of movement and interaction,and has certain reference significance for the compilation of physics textbooks.This paper mainly includes three parts,which are:The first part is hierarchy model of physical concepts.First,study the connotation of the physical concept;Second,determine the "physical and physical laws" in the hierarchical model;Third,determine the "core concepts" in the hierarchical model;fourth,determine the "material concepts;the concepts of movement and interaction;energy concepts" in the hierarchical model;Fifth,determine the "physical concept" in the hierarchical model.The second part is hierarchical model for concepts of movement and interaction.First,analyze the content of curriculum standards related to the concept of movement and interaction.Second,build a hierarchical model of the concept for movement and interaction;third,explain each level in the hierarchy model.The third part: adaptability analysis of physics textbooks based on the concept of movement and interaction.First,the adaptability analysis of textbooks based on the "concept,regularity" level in the hierarchical model for concepts of movement and interaction;secondly,the adaptability analysis of textbooks based on the "core concepts" level in the hierarchical model for concepts of movement and interaction;Third,the adaptability analysis of textbooks based on the level of "motion and interaction" in the hierarchical model of the concept of movement and interaction.Through the above studies,the conclusions are:First,there are four levels of hierarchy model of physical concepts.From the bottom up,the first level is the physical concept and the physical law;the second level is the core concepts;the third level is the material concept,the concept of movement and interaction,and the energy concept;the fourth level is the physical concept.Among them,physical concepts and physical laws are important components of physics knowledge,and they are the basis of physics learning;physical core concepts have a leading role in physical concepts and physical laws;material concepts,concepts of movement and interaction,and energy concepts are the important part of physical concepts.The formation of physical concept helps students to have a deeper understanding of the material world and thus promote the formation of high school students' world outlook.Second,there are four levels of the hierarchical model of the concept of movement and interaction.From the bottom up,the first level is the physical and physical laws related to movement and interaction;The second level,The core concepts are movement,types of interaction,forces and movement;the third level is the concept that the students can form in the senior high school;The fourth level is movement and interaction concept.Among them,There are 113 physical concepts and 74 laws in the physical textbook.The three core concepts of "movement","types of interaction" and "force and movement" can be further divided."Movement" can be divided into mechanical movement,thermal movement,electromagnetic movement,microscopic movement,movement of celestial body system;"Types of interactions" can be divided into gravitational interactions,strong interactions,weak interactions,and electromagnetic interactions;"Force and movement" can be divided into no force,a pair of balance forces,and an unbalanced force.The eight concepts that can be formed in high school are related to movement and interaction.Third,based on the movement and interaction hierarchy model,The physics textbooks pay attention to the basics of the teaching materials,and pay attention to the basic contents such as the concept of physics and the laws of physics.The new curriculum standard adds,cuts,splits,and merges some of the course content of the experimental curriculum standard.Textbooks need to be adjusted according to these changes.The new curriculum standard merges and deletes the theme of the experimental version,highlighting the content of the curriculum around the core theme.Therefore,physics textbooks should focus on the concepts and laws in the integration of textbooks around core concepts.Compared to the course objectives of "Knowledge and Skills,Processes and Methods,Feelings,Attitudes,and Values" in the experimental Physics Curriculum Standards,the 2017 edition of Physics Curriculum Standards proposes physical core literacy.Therefore,high school physics textbooks should focus on cultivating students' concepts of movement and interaction.
