The ability of physical modeling is the key ability of students to solve practical problems.In the junior high school stage,if the student do not have a solid foundation for cultivating students’ physical modeling ability,properly cultivate students’ modeling ability,in the high school stage when having highly academic pressure,you will encounter many difficulties and obstacles.This thesis mainly analyzes the status quo of students’ modeling ability by solving the current situation of junior physics problems,and studies the basic factors that have a great influence on students’ modeling ability,so as to propose teaching strategies and improve students’ physical modeling ability..The first chapter introduces the topic from the development of society,and expounds the important position of physical modeling ability in physics teaching from the perspectives of the needs of talent cultivation,the status quo of curriculum reform and the trend of examination content.Through the review of the literature,the status quo of the original physical problems and physical modeling capabilities were analyzed,and the purpose and significance of the research were clarified.The second chapter clarifies the original physics problem,physical model,physical modeling and its concepts and characteristics,and studies the concepts and profound meanings of logic and logical thinking ability,which laying a solid theoretical foundation for the research of this thesis..Based on this,the hypothesis of the relationship between logical thinking ability,mathematical foundation,knowledge base and physical modeling ability is proposed.The third chapter is the research part of this thesis.Firstly,the test method is used to test the current situation of the modeling ability of junior high school students,and to understand the status quo of students to establish physical models to solve the original physical problems.And through the questionnaire survey method to examine the students’ ability of logical thinking and the status quo of mathematics.In addition,through the oral report method to assist the questionnaire to understand the process of students to establish models to solve the original physical problems,and to study the impact of students’ knowledge base on the ability to build physical models.Using spss to analyze the data,it is concluded that if students do not have corresponding knowledge storage or related concepts,laws,etc.,it will be difficult to establish a model;students’ logical thinking ability also greatly affects students’ modeling ability,which has a greater impact.It is the ability to derive theoretical evidence;the mathematical foundation has a relatively small impact on students’ ability to build physical models,which mainly affects the computational process after s tudents deal with physical representations.The above results confirm that the relationship hypothesis proposed in Chapter 2 is scientific.According to the research results,the fourth chapter proposes teaching strategies from the five perspectives of new teaching,problem teaching,experimental teaching,review teaching and introduction of primitive physics problems to improve students’ ability to build physical models.Through the design of one-to-one correspondence teaching schemes implemented in the corresponding grades and classes,according to the performance of students in the classroom,the change of students’ physical attitudes and the modeling of actual problems,it can be seen that the teaching strategy works well.It has mobilized the students’ enthusiasm for solving the original physical problems and practical problems,and has greatly helped to cultivate students’ physical modeling ability,filling the blank of cultivating students’ modeling ability in the junior high school.The fifth chapter summarizes the content of the whole study,and clarifies the shortcomings of the research and the prospects for the research. |
