A Study Of Contextual Teaching To Promote The Formation And Development Of Physics Concepts Among Sophomore Students

The core literacy of physics includes four aspects: physical concept,scientific thinking,scientific inquiry,scientific attitude and responsibility.Therefore,the concept of physics has a very important significance in the core literacy.Ideas exist in context,are formed in context,and develop in context.The research on the situational teaching that promotes the formation and development of high school students’ physical concepts is as follows:（1）Based on the research on physical concepts and situational teaching in the curriculum standards,the in-depth study of the connotation of physical concepts and situational teaching,combined with domestic and foreign research reviews,based on Li Jilin’s situational teaching theory,constructivist learning theory,and advanced learning theory Find out the close connection between physical concepts and situational teaching and the important significance of situational teaching for the formation and development of physical concepts.（2）By developing PISA test questions and analyzing the structure of college entrance examination questions,a questionnaire was designed to test the physical concept level of senior two students.The level of physics concepts in the physics curriculum standard was divided into evaluation scales to analyze the pre-test results.Students’ physical concept level is low,and most students’ physical concept is at level 2.（3）The college entrance examination questions can reflect the core literacy of physics,and it is an important method for selecting talents.Therefore,a benchmarking study was conducted on the physical concepts and situations in the 2018-2021 college entrance examination Physics II（B）paper questions,and the scientific situation was summarized.According to the summarized situation,the situational teaching strategies suitable for the formation and development of physical concepts are expounded and applied in the author’s educational practice.This paper presents two teaching cases: Electric Field,Electric Field Strength;Momentum,Momentum Theorem.（4）After practice,a post-test is conducted,a questionnaire for the post-test of physical concept level is designed,and the results of the post-test survey are analyzed and a conclusion is drawn: the overall physical concept level of the students is at level three,and the post-test questions are more open and the situation is more diverse.The students’ physical concept level is not only formed but also improved by at least one level.This also proves that the author’s research on situational teaching to promote the formation and development of high school students’ physical concepts is very meaningful.Situational teaching can effectively promote the formation and development of high school students’ physical concepts.develop.
