Design And Practice Of Constructing Physical Model Based On Experimental Inquiry

The "General high school Physics Curriculum Standards"(2017 edition,2020 revision)clearly put forward the requirements for testing the literacy of model construction in the curriculum objectives,academic quality,implementation suggestions and appendix.However,as an invisible teaching examination content,the training of model construction literacy is significantly more difficult than the examination of physics teaching itself,which brings troubles to the teaching work of physics teachers.Therefore,how to find the balance between the two is what we need to think and discuss.This paper puts forward the idea of building a physical model through the teaching method of experimental inquiry,writes relevant experimental teaching design and carries out practice.In this paper,literature analysis is used to investigate the current research status of physical modeling teaching at home and abroad,define relevant core concepts,and analyze the needs of introducing exploratory experiments into physical modeling teaching based on theoretical basis.By sorting out the types of physical models,the experimental classification of high school physics textbooks and the teaching function of physical experiments,the close connection between experimental inquiry and model construction is established,the advantages and disadvantages of exploratory experiments in the construction of physical models are dug out,and the teaching suggestions on the construction of physical models by experimental inquiry are put forward.Two experimental teaching cases were designed based on experiment types,and the teaching results of case practice were analyzed by case analysis method.The results show that designing and developing experimental worksheets can effectively promote students’ independent construction of physical models,help students to make physical models in their minds visible,and develop students’ core literacy of physics.
