Research On Application Of Physics Models In Senior High School Students

Physics is a basic discipline in the field of natural sciences.It studies the basic structures,interactions,and laws of motion in nature.The Ordinary Senior High School Physics Curriculum Standards(2017 Edition)puts forward new requirements for students' physical model capabilities.The physical model is one of the important contents of improving the core qualities of students' physical sciences,and it is also the main way to cultivate students' innovative spirit and practical ability.Understanding the students' physical model construction level and application status will greatly help improve the efficiency of physics teaching.Physics learning of Grade One in Senior High School is the basic stage of physics knowledge learning.Therefore,it is very necessary to investigate and study the physical conditions of senior students and the problems existing in their application.On the basis of related research,this research developed the students physical model application status questionnaire.Students from the students' awareness of physical model,physical model building,student physical model of the application effect,the physical model of the prominent function,and the importance of physical model to understand the student physical model application status.Test results show that the questionnaire consistency Cronbach 's alpha coefficient is 0.910,the structure validity of KMO value of 0.904,shows that the questionnaire has good reliability and validity test,can more accurately reflect the student application present situation and existing problems of the physical model.The results of the survey found that the student to the physical model definition,classification and modeling significance to understand less,discriminant insufficient understanding of common physical model,applied conditions of the model is not clear,lack of basic thinking of physical model is established,vulnerable to interference problem representation,can't distinguish the main and secondary factors,etc.The level of application of the physical model of students to a certain extent there is a difference in the type of school,the gender of the students,the proficiency of the student's physical model application and the sense of achievement of the student's physics learning are positively correlated to a certain extent.Aiming at these problems existing in the application of students' physical models,the study proposes: strengthen the students' understanding of the physical model essence,to highlight the convenience of its application;to clarify the applicable conditions of the physical model,establish an accurate physical model;enhance the physical model knowledge matching Ability to improve the efficiency of student model construction;apply standardized model teaching mode to develop students' programmatic thinking;pay attention to teaching students in accordance with their aptitude,and reduce students' gender differences in physical model applications.Through case studies,the problem-solving strategy is applied to practice,so that students can clearly define the conditions of use of the model,experience the modeling process,master the method steps of model building,and learn to apply physical models to solve practical problems.Finally,it is found through the case that the countermeasures to solve the application problems of the students' physical models have a certain positive effect on the teaching practice,and can provide reference and reference for the teaching of related content.
