Exploration And Practical Research On Teaching Of Concept Construction Of Physics In High School

With the improvement of the quality requirements for personnel training in the new era,the key to the current new curriculum reform is to carry out moral education and develop the value of discipline education,and the core literacy put forward conforms to this requirement.Implemented in physics teaching,the new high school physics curriculum standard issued at the end of 2017 has officially put forward the curriculum goal of cultivating students' core physical literacy.Therefore,how to develop the core quality of students' physics is an important topic that the front-line teachers should explore.As an important aspect of the core quality of physics,the concept of physics is a kind of physical consciousness rooted in the students' mind and used to guide the practice of life.However,it is found that there is a lack of such in-depth research.Therefore,how to effectively promote the construction of students' physical concept in high school physics teaching is an urgent problem.Therefore,this paper puts forward the research and practice of high school physical concept construction teaching,trying to find an effective way to implement high school physical concept construction teaching.The construction of physical concept focuses on the internal logic of knowledge itself,the formation process of knowledge,and the use of relevant physical knowledge to solve specific practical problems,and finally points to the solution of practical problems in the real situation.This study is based on the construction of physical concepts.First of all,this paper analyzed the current situation of the research on the construction of physical concept and the current situation of the construction of physical concept teaching in senior high school.Then,according to the definition of physics concept in the standard of physics curriculum for senior high school,the paper analyzed the content system of physics concept.On this basis,combined with the theory of cognitive assimilation,the advanced teaching mode of "three steps of basic concept-core concept-physical concept" was creatively put forward.Combined with inquiry learning theory,cognitive structure theory,convergence combination method and other educational teaching principles,this paper discussed the sub model of the formation process of each step,and explained each link of the sub model with teaching cases.Then,based on the "three steps" teaching mode and sub mode,the teaching practice of the physical concept construction of the law of conservation of mechanical energy was carried out,and used the theory of solo classification evaluation to evaluate the construction of physical concept in teaching practice.Based on the "three steps" teaching mode,the students in the experimental class have a better ability to solve real problems.Therefore,the long-term application of "three steps" advanced path teaching mode in the teaching of physical concept construction can effectively promote the construction of students' physical concept.This model has reference value for the high school front-line physics teachers to carry out the teaching of physical concept construction.
