Research On The Application Of High School Physics Diagram

Because of the high level of abstraction and logic in high school physics knowledge,many students are having difficulty learning at this stage.The physical diagram is a combination of image and abstraction.Applying it to teaching can effectively reduce the difficulty of students' understanding,help teachers improve teaching efficiency and enhance teaching quality.Carrying out applied research on the physical diagram helps to cultivate students' physical core literacy.The process of constructing the diagram thinking is also the process of the development of image thinking,logical thinking,and innovative thinking.The physical diagram from life to life can help students better understand nature.The author of this thesis first analyzed the physics questions in the college entrance examination and found that the physical diagram-like questions in the examination questions over the years occupy a high proportion.The research on the curriculum standards found that the diagram teaching meets the requirements of the curriculum standards.The physical diagram and the core literacy have more similarities.Facing the current state of divergent definitions of the physical diagram,the author has sorted out researches at home and abroad.The research believes that the physical diagram is a visualized geometric figure and abstract physical meaning,concept,a "mental diagram" that combines laws.The physical diagram is the result of the combined effect of figurative thinking and abstract thinking,which can be expressed by means of diagrams and text symbols.The display form of physical diagram is a schematic picture with physical meaning.The author carefully classifies the physical diagram from different angles,and explores the physical diagram's characteristics of image,dynamic,abstract,and constructive.In order to understand the current situation of physical diagram cultivation at this stage,the author independently designed and implemented student questionnaire surveys and teacher interview surveys.The first part of the student questionnaire is a multiple-choice questionnaire,which surveys students' attitudes and learning habits towards the diagrams.The second part of the questionnaire is a form of drawing test questions,which investigates the problems of students' self-construction of the diagram.Statistical analysis of thequestionnaire found that most students liked the physical diagram,but they didn't know enough about the application of the physical diagram.There were many problems in the construction of the diagram,such as rough draw,poor comprehensiveness,process confusion,and low degree of integration of diagrams and physical knowledge.Teacher interviews revealed that teachers were unclear about the concept of physical diagrams and had less understanding of application and training.In order to improve the teaching of physical diagrams at present,the author creatively designed more than fifty schematic diagrams on the application of diagrams,combined them with eight teaching clips,presented the process of diagram development,and discussed how physical diagrams help students understand physics,application of concepts and laws,solving physical problems,understanding ideal experiments,participating in experimental design,and effective review.In order to avoid the problems of physical diagram in the questionnaire survey,the author studies the process of constructing physical diagram and explores seven corresponding training strategies.In order to verify the effectiveness of the cultivation strategy,the author carried out the cultivation experiment of physical diagrams,and implemented the teaching design of "the charged particles moving in a uniform magnetic field" and "thematic course of physical diagram methods" based on the cultivation strategy design for senior two experimental class.The experiment found that the training strategy can effectively improve the ability of students to construct physical diagram,and many problems exposed in the questionnaire survey have been improved.Special lessons help students understand the concepts and applications of physical diagrams.The author believes that the enrichment and development of physical diagram thinking is a long-term process,and expects that in the future,physical diagram teaching will be well known by more front-line teachers,and more concise and effective physical diagrams will be developed to better serve for physical teaching.
