Training Of Modeling Ability Of Physics For Senior High School Students

Since the introduction of the General High School Physics Curriculum Standard(2017Edition)in 2017,the core literacy of physics curriculum has become the core of the high school physics curriculum standard.As an important part of scientific thinking,model construction is not only the starting point to visualize physical concepts and train students’ scientific thinking,but also an important way to represent the physical situation.It is the key ability that middle school students must have and need to develop constantly,and plays a pivotal role in physics.In the introduction part of this thesis,the background of this research is described.First of all,the author uses Citespace to make visual analysis of relevant domestic and foreign literatures on “physical model”.It is found that the current research of scholars at home and abroad basically takes model construction as a link in the process of teaching design,and most of them do not elaborate on the process of model construction.Therefore,this article advocates students,through the process of modeling,to internalize the physical model in their mind,so that students have the initiative to adopt the method of modeling to solve problems.After that,the author also puts forward the research content and research methods of this thesis,and sorts out the overall context of this thesis.The second chapter introduces the theoretical basis of this research.On the one hand,from the perspective of pedagogy and psychology,based on the theory of cognitivism and constructivism,this thesis points out the learning view and teaching view of this thesis.On the other hand,“model-centered teaching method” proposed by David Hestenes is the main theoretical framework of this thesis,which points out the origin and meaning of model teaching method.The third chapter is about the necessity to do research on the teaching of high school physical model construction.Through the questionnaire survey of students,the current situation of the knowledge and modeling ability level of senior one students about physical model is mastered,and this will serve as the basis of model construction teaching.Through interviews with senior high school teachers,we record the teaching methods adopted by front-line teachers and the importance of physical models for them.The fourth chapter is about the establishment of physical model teaching mode.First of all,all physical models of mechanics taught in high school are sorted and classified.Secondly,this thesis summarizes the main factors,secondary factors and irrelevant factors of all models within the research scope,and lists keywords for better understanding.Finally,the modeling process of“generalization →contrast →deductive reasoning → induction” is established,and the free fall movement is illustrated as an example.The fifth chapter describes the implementation and effect evaluation of physical model construction teaching cases.Based on the model teaching mode advocated in this thesis,the author chooses typical cases for teaching design,and these examples are implemented in practical teaching.Evaluation tools of this article is Lopes provided by the concept of “domain”physical modeling ability evaluation index as the theoretical basis,and is compiled according to the international recognition of modeling capability assessment scale FCI and MBT test.In this evaluation,two classes with no difference in admission level are selected as parallel classes.At the end of the semester,SPSS is used to conduct the independent T-test on the evaluation results,and the results showed that there are significant differences between the two classes.The results of the experimental class are better than that of the control class,that is,the effect of modeling teaching is better than that of ordinary teaching,which is worth promoting.Finally,by reflecting on the whole research process and summarizing the advantages and disadvantages of this study to further improve it,we can study the model construction teaching in much greater detail,so that this research can be applied to the teaching of high school physics.
