Practical Research Of Model Teaching Of High School Physics

By analyzing the proposition trends of the college entrance examination in recent years,it will be found that the focus of the study shifts from mastery of knowledge to analysis of problem-solving skills.Most of the content of the questions comes from actual production and life.This kind of problem requires students to follow the information in the question and Establish related physical models to deal with problems.Through the construction of physical model,complex problems can be abstracted and the essential reasons can be highlighted.It is an essential way of thinking when learning physics.However,it is found from teaching practice that students do not know where to start when dealing with such problems.Lacking of modeling consciousness leads to a decline in grades and gradually loses their interest and enthusiasm for physics learning,so most students think that physics is difficult to learn and useless.In order to change the existing situation,it is urgent to carry out physical model teaching.This thesis is divided into five parts.In the first part of this thesis,the definition,classification main characteristics and the research background of this paper are discussed theoretically.This thesis mainly discusses the definition,classification,main features of physical model.The second part of this thesis analyzes the current status of high school physics model teaching,understands teachers and students' research on cognition and methods of high school physics model teaching,In the third part of this thesis,a questionnaire survey is conducted to understand the students' mastery of physical models,and analyze the main problems in the process of modeling and applying models to solve problems,as well as the main factors causing difficulties in solving problems.Analyze the results of the questionnaire survey,understand the difficulties of students in building the model,and find ways to break through in the later classroom teaching practice.The fourth part of this thesis discusses the teaching mode of physical model teaching in senior high school theoretically,and analyzes several typical teaching cases.In the link of teaching measures,it classifies students' cognitive impairment of modeling,and finds corresponding strategies.In the fifth part of this thesis,we design the experimental scheme and carry out the practice of physical model education in senior high school.We select the experimental class and the control class in the first and second grade of senior high school.By analyzing the results of the two monthly examinations,the mid-term and the final examination,we compare the overall effect of the experimental class and the control class,the difference of the teaching effects of different levels of students in the same grade,as well as for boys and girls.The difference of teaching effect.This thesis reflects on this study and summarizes the results of the study.In the process of research,the author has gained a lot of valuable experience in the process of encountering and solving problems.These experiences have improved the performance of the two teaching classes taught by the author.When you encounter a problem,you can consciously search for the physical model you have learned,so that you don't lose track of it.Although most students can't make big breakthroughs in a short time,most students have improved compared to before.The author has obtained very valuable data through the examination of physical model teaching.These data have certain guiding significance for future teaching work.
