Teaching Practical Study Of The Transfer Between Physical Models And Original Problems In Junior Middle School

Physical model plays an important role in the physics teaching of junior high school,and the original problem is closely related to student life.It is of considerable importance that applying the physical model to the solution of the original problem which original problem make contributions to the understanding of application of the physical model for students.This is a critical process to cultivate the students' scientific literacy.Therefore,the transfer between the physical model in junior high school students and the original problem is the research topic in this dissertation.In addition to the research background and research prospect,the main content of this dissertation can be expressed as follows:1.Theoretical explanation.At first,the related physical models have been introduced,and the physical models involved in the junior high school have been discussed.Later,the related theories about the original problems have been investigated and classified.Combining the characteristics of physical models with characteristics of student's cognition,the Five selection principles of original problems have been discussed.Finally,the theoretical basis of migration and migration theory have been systematically illustrated.2.Practical research.From the chapter 3 to the chapter 4,it mainly analyzes the factors——Five Student's Factors,Three Teacher's Factors,and Four Textbook Factors—— which would affect the migration between the physical model of the junior high school and the original problem in combination with educational theory.Next,the transfer between the physical model and the original problem has been divided into three parts——the transfer from physical models to original problems,the transfer from original problems to physical models,and the intermigration between physical models and original problems.And relevant cases and some examples in combination with teaching practice have been given.As a basis for reflection on the impact of the transfer between the physicalmodel and the original problem on teachers and students,which is the key part of this dissertation.According to practical research,it is concluded that in Junior Middle School physics teaching,the transfer between the infiltration physical models and original problems is not only feasible but also has certain innovations,which is conducive to stimulate students' interest in physics learning and the long-term development of students and teachers.Subsequently,in order to optimize the interaction between the physical model and the original problem in junior high school physics,research would be extended to the chapter review of the physical model,and the physical model would be generated from single to multiple.
