Teaching Research On The Application Of Limit Thought In Physics Kinematics In High School

Both physics teaching and problem solving need to use mathematical tools,and limit thinking is one of the important mathematical methods.This article is guided by the specific requirements of the "General High School Physics Curriculum Standards" for teachers in the knowledge teaching of the mechanical movement module,and consults the relevant literature to sort out the core concepts and theoretical foundations.Through questionnaire surveys and diagnostic tests,we can understand the shortcomings in the process of learning physics and solving physical problems with the help of extreme thinking.Through interviews with physics teachers,we can understand the current teaching status of extreme thinking physics.On the basis of analyzing the specific problems of students and teachers separately,and organizing and summarizing the content of compulsory physics textbook compulsory 1 and compulsory 2 of the textbook version of high school physics,the corresponding teaching strategies are proposed: 1.Organic integration of high school physics movement Relevant content related to extreme thinking in learning;2.Explore the average speed and instantaneous speed through experimental exploration;3.Make the extreme process dynamic,use Geogebra software to make relevant dynamic images,change the limitation of traditional teaching only using textbook resources,and allow infinite differentiation,The process of infinite approach is dynamically displayed in front of the students;4.The limit state is visualized,using the virtual software Algodoo to make the model of the rope ball and the rod ball,by changing the speed of the ball when it reaches the highest point during the movement To show concretely the conditions under which the ball can pass the highest point in different models.Finally,through teaching practice,the teaching practice of the proposed teaching strategy is carried out,and the ability of students is evaluated and compared to verify the effectiveness of the strategy.The thesis hopes that through this teaching research,it will provide specific reference teaching practice for the application of extreme thinking in the teaching of physical kinematics in high school.
