Study On The Relationship Between Force And Movement

In the basic education stage of our country,students have the problem of expanding and deepening their understanding of scientific concepts in the course of learning.In physical learning,many physical concepts of "the relationship between force and movement" run through the whole physics learning,but the students' learning only stays in a certain chapter of the knowledge in a certain period without the penetration of knowledge.Therefore,taking the core concept as the basis to study learning advanced,we can understand the students' learning level and help the teachers to better help students to form a complete knowledge system.This study chooses the relationship between force and exercise as the research topic.The main research contents and results are as follows:In the first part,the advanced hypothesis of "relationship between force and movement" is preliminarily constructed.Through combing the relevant literature to understand the research achievements in the field of learning in terms of force and movement,we can get relevant research ideas.This paper analyzes the primary and middle school physics curriculum standards,and combs the main learning content and order of "the relationship between force and movement" in the basic education stage of our country,and initially constructs the learning advanced hypothesis of "the relationship between force and movement".The second part,modify the learning advanced hypothesis.Relying on the FCI test,test the level of high freshmen and senior students,through the Rasch model analysis and comparison of the characteristics of the two,through interviews with the teachers,to understand the related situation in students' learning,and modify the relevant contents of the advanced hypothesis.Through the analysis of the questions,it is found that the students' understanding of the impulse will affect the first law of Newton and the learning of the related knowledge of the curve motion.This part is added to the learning step,and the relationship between the first law of Newton and the circle movement is refined.The third part is to comb students' misconceptions about force and movement.Through the analysis of the FCI test questions and the interview to the students,we find out the wrongconcepts of the students,such as the impulse,the falling object,the flat throwing movement,the force and the counterforce among the objects in different state of movement,and the students have more misunderstandings in their study.We further analyzed the cause of the mistake.The fourth part is teaching design based on learning progress.The understanding of learning advance can help teachers set more appropriate teaching objectives in the course of teaching design,and the error analysis of students will help the choice of teaching strategies.The fifth part is the implementation of teaching plan and classroom observation.It is found that the teaching design based on advanced learning has achieved good results.The correct rate of answering questions in the FCI test is higher than that in the second grade.This not only confirms our advanced analysis,but also shows the effectiveness of our strategy.To sum up,from the teaching materials,curriculum standards and students' practice,this study constructs the learning approach of "the relationship between force and movement",combs the students' misconceptions about the force and movement,and puts forward the strategies of teaching improvement.On this basis,the teaching practice and observation have been carried out,and a considerable effect has been achieved.It is hoped that this article will not only help the teaching of force and motion,but also provide an effective and feasible research method for other topics in physics teaching and research.
