Research On The Level Of Physical Modeling Of High School Students Based On The Level Of Scientific Thinking

Since the promulgation of the general high school physics curriculum standard(2017 edition),high school physics teaching has paid more attention to the cultivation of students'core literacy.The curriculum standard clearly proposes that the high school physics curriculum aims to implement the fundamental tasks of Lide Shuren and further enhance the core literacy of students' physics disciplines..As one of the important abilities of the core literacy of physics,physical modeling ability plays an important role in students'physical learning and even lifelong development.Foreign research on model teaching is relatively mature.Domestic research on modeling and training started late and achieved certain results,but there is not much research on modeling level.Based on the construction of physical models,this study designs a set of five-level survey volumes based on the division of physical models in the scientific thinking hierarchy of the general high school curriculum standards(2017 edition),and selects a four-star high school in Jiangsu.Students in the first,second and third grades as the research object to measure the level of physical modeling of high school students.The sample data was analyzed by SPSS23.0,and the status analysis and correlation analysis of the physical modeling level of high school students were made.Through statistical analysis and correlation analysis of the samples,it is found that:(1)the physical modeling level of high school students is not high overall,but the level of modeling increases with the grade level;(2)at the level of physical modeling,boys and girls There is almost no significant difference;the level of physical modeling of high school students is positively correlated with physics academic achievement and mathematics academic achievement;(3)most of the difficulties in the physical modeling process of high school students occur from the original problem to the physical problem.In other words,the main problem of high school students modeling lies in the characterization of the model.In view of the above research results,in order to better promote the development of students' physical modeling ability,several suggestions for teacher teaching are provided for reference:strengthening model penetration and improving modeling awareness;attaching importance to representation ability,strengthening model transformation;changing teaching concept Pay attention to the cultivation of thinking;respect the interdisciplinary relationship and improve the modeling.
