Broad Investigation Of Newton's Second Law F=ma And Its Enlightenment To Teaching Materials And Teaching Methods

Newton's second law is the core of classical mechanics and the focus of high school physics teaching.The textbook deals with this by first exploring the relationship between acceleration,force,and mass through experimental investigations,and then drawing Newton's second law,but the design of the experiment lacks rigorous logic.The dissertation first traces the origin and development of Newton's second law,digs out scientists' thinking methods,and analyzes the teaching content of Newton's second law in new textbooks;then combines the students' cognitive level to cultivate students' physics disciplines from the perspective of core literacy,the course of Newton's second law was designed using the history of physics,and teaching practice was carried out.In addition,quasi-experimental research and questionnaire surveys are used to evaluate and analyze teaching effects.Teaching practice shows that the teaching of Newton's second law integrated into the history of physics can stimulate students' learning interest,deepen students' understanding of knowledge,promote the development of students' scientific thinking,and cultivate students' critical and critical ability and innovative spirit.In addition,it has a certain positive impact on students' academic performance.Based on the results of textbook analysis and the effectiveness of teaching practice,reasonable suggestions are made for textbook compilation and teacher teaching.This thesis enriches the resources of Newton's second law in the history of physics,provides new ideas for teaching materials,provides a new perspective for teachers' teaching,and provides a new practice path for the achievement of core literacy of students in physics.
