Research On Junior High School Physics Teaching Strategies Based On The Development Of Motion And Interaction Concepts

It is proposed in the physics curriculum Standard of compulsory education(2022edition)that the purpose of improving the core literacy of all students is to emphasize the implementation of the educational value of physics curriculum.The core literacy of physics is the concentrated embodiment of the value of discipline education,as well as the comprehensive embodiment of the basic knowledge of science,key ability,scientific emotion,quality of thinking,emotional attitude and values formed by students to meet the needs of personal learning and lifelong development."Physical concept",as one of the important components of the discipline’s core literacy,is the conceptual basis for describing phenomena and solving problems from the perspective of physics,and is an abstract understanding of physical concepts and laws.It mainly includes material concept,motion and interaction concept and energy concept.In the new curriculum standard,although the content requirements and academic requirements for each subject are given,but no specific practical advice is given.In this paper,the concept of motion and interaction among physical concepts is selected as the research object,and focuses on how to change from " calculation exercise" to "problem solving",how to transition from learning book theories to explaining life phenomena,and how to penetrate physics concept teaching,so as to promote the improvement of students’ core literacy.This paper firstly studies the literature about the concepts of physics and motion and interaction.It is found that most literature studies the strategic application of sports and interaction concepts in high school,while content strategy studies in middle school are few,and the extraction,sorting,induction and analysis of contents in middle school textbooks and new curriculum standards are also few.Therefore,this paper firstly compares and collates the modification,addition and deletion of the curriculum objectives and content requirements in the new and old curriculum standards.Secondly,it collates the content of the concept laws related to the movement and interaction concepts in the Shanghai junior high school physics textbooks to help teachers clarify the content of the textbooks,grasp the teaching objectives,and deeply understand the specific content and requirements of the concepts.Based on the above research,based on the curriculum objectives and the characteristics of students’ physical and mental development,the author sets questions from the aspects of students’ cognitive dimension,ability dimension,affection dimension and teachers’ teaching evaluation,A questionnaire was designed to investigate the current situation of students’ ideas of movement and interaction,and summarize the current situation problems affecting the formation of students’ concepts.Finally,practical and feasible strategies based on the problems and case design based on concept construction are given to help students abandon wrong cognition,construct knowledge system,infiltrate people’s thinking,and provide reference suggestions for front-line teachers.
