Practical Research On Model Construction In Physics Teaching Of High School

Physics is a natural science that studies physical phenomena and their changing laws.Physical phenomena are complex,and these complex relationships reflect the regularity and contingency in the phenomena,which makes the research process of physics more complex.It is precisely because the problems analyzed and studied in physics are often very complex.In order to facilitate the analysis and research,people simplify the physical situation.Simplification is to retain the main factors of the whole process,highlight the main contradictions,ignore the secondary factors,scientifically abstract the essential characteristics of the actual problems,and form a structural system,an ideal physical concept or physical system that can reflect the essence of the object.This ideal structure is called a physical model.Physical model is a high generalization of physical knowledge and a concentrated embodiment of physical thinking.The mastery of high school physics knowledge requires students to have good thinking ability.It is necessary to analyze problems through abstract thinking research on the basis of basic knowledge.Corresponding teachers need to train students’ thinking ability of model construction when teaching physics knowledge system.Visualizing the abstract knowledge system can enable students to quickly grasp the difficult points of knowledge,broaden their thinking,and make their knowledge framework more systematic.As an effective way for students to learn physics,physical models can not only help students visualize abstract problems,reduce the difficulty of physical analysis,and enable students to quickly grasp the key and difficult points of knowledge,but also have the functions of cultivating students’ ability to analyze and solve problems,strengthening physical thinking,improving innovation consciousness,and broadening perspective.When using physical knowledge to solve practical problems,reasonably build corresponding models to grasp and solve problems more easily.In physics teaching,the effective use of physical models can help teachers achieve the effect of increasing efficiency and reducing burden-reducing teaching difficulty and improving teaching effectiveness.It can be said that physics teaching cannot be separated from physical model.The physical model is just like the stepping stone to open the knowledge building of physics.Whether it is for teachers or students,the effective use of the physical model is of great benefit to themselves.Of course,while using the physical model,we should also pay attention to the relevant problems in the teaching of the physical model.After all,everything has two sides,and scientific use will make the results more remarkable.This topic classifies the current high school physical models,and discusses the significance of the construction of physical models in teaching in combination with pedagogy and psychology;Under the guidance of the new curriculum theory,it combs the characteristics and implementation strategies of model construction in teaching,studies the practical methods of model construction in combination with teaching practice,and explores effective teaching practice and physical learning mode of physical model construction.The research on the model building practice in high school physics teaching is mainly divided into six chapters.The first part introduces the background and research significance of this paper.After consulting a large number of existing literatures and combing the research status at home and abroad,the research content and methods of this paper are clarified.The second part is a review of relevant research theories,which sorts out and introduces the physical models and the theories involved in the model construction,combs and classifies the common models of middle school physics,and studies the methods and functions of model construction;The teaching necessity of the model construction is demonstrated from the perspective of educational psychology.The third part is the research on the practical application of model building in high school physics teaching.The research object is selected to understand the students’ ability of model building in the actual situation and their tendency to the teaching content and methods through questionnaire survey.Sort out the survey results,analyze the actual ability of student model construction,feed back some problems in teaching,and give corresponding effective suggestions for teaching effect.The fourth part is the research on the teaching principles and Strategies of high school physics model construction.Based on the teaching objectives of model construction,the application principles and implementation strategies of model construction are summarized.The fifth part is the general operation procedure of model teaching.It selects some teaching contents from the preliminary preparation,classroom teaching activities,and after-class evaluation and reflection to design the teaching plan in detail,and summarizes the matters for attention in the application of model construction in high school physics teaching.The sixth part is the practical application of model construction in high school physics teaching.Combined with the method of model construction,based on the teaching principles of scenario diversity,method diversity,student subjectivity,scientific feasibility and simplicity of model construction,the implementation of model teaching is mainly composed of five teaching stages: scenario analysis-model construction-model analysis-model processing-model expansion.Combined with the above implementation strategies,the actual modeling ability of students was analyzed according to the questionnaire survey and interview,and the practical application of model teaching was studied.Investigate and sort out the final practical results,and verify the application effect of the model construction.
