The Applied Research Of Primitive Physics Problems In Physics Teaching In Junior Middle School

Physical modeling is an important method to learn the laws of physics and explore the scientific world.Mechanics is the foundation of physics knowledge system in senior high school.In the teaching,the teacher guides the student correctly through the observation and the experiment,and use the analogy,the inference and so on the method establishment physics model to solve some kind of physics question,thus raises the student's modeling ability,this has the very important significance for the promotion student's physics core accomplishment.This article first has carried on the interview a line of high school physics teacher,and the high school students conducted a questionnaire survey,the results show that high school students with low levels of physical modeling ability,high school physics teacher lack of system modeling of physical teaching theory and teaching design,and then further study of a large number of related literature at home and abroad and the theory of education,physical modeling teaching are analyzed and the feasibility and the necessity of physics teaching in high school and then based on the ordinary high school physics curriculum standard(2017 edition)"physics textbooks for high schools and people,on the basis of the modeling teaching theory and constructivism theory,and combining with psychological development characteristics of high school students,This paper establishes the basic principle of "student-centered,scientific,theory connected with practice" in the modeling teaching of high school physics mechanics,and designs the teaching design scheme of "creating situation,establishing model,forming concept rule,applying model and feedback evaluation".According to this,three teaching cases of elastic model,slide model and conveyor model are designed,and corresponding teaching practice is carried out in a key one.The teaching feedback survey shows that the application of this teaching plan can stimulate students' interest in physical modeling and improve their ability to apply physical model,with good effect.
