| Physics is one of the main subjects in middle schools.In the development of middle school curriculum reform in recent years,the connection between physics teaching in middle schools and high schools has become an important subject in the new curriculum reform.With the changes in the depth and breadth of course contents,teaching methods and learning requirements,students who have just entered the new high school are often at a loss."physics is difficult to learn" has become the consensus of most students in the learning process of high school.Faced with the recognized most difficult subject,students who enter high school for the first time find it difficult to find their own learning style,compared with junior high school physics,high school physics makes them helpless.This paper adopts the literature research method,theoretical analysis method and investigation method,takes the senior high school students and physics teachers as the research objects,and on the basis of clarifying the relevant theoretical framework,analyzes the current situation of physics cohesive teaching in middle and high school,and identifies the main problems existing in the current physics cohesive teaching in middle and high school.Taking the students and physics teachers of a senior high school as the research objects,this paper studies the current situation of physics connection between senior high school and junior high school in senior high school physics teaching,identifies the main problems existing in senior high school physics teaching from the aspects of textbooks,teachers and students,and analyzes the causes of these problems.In view of these problems,based on the relevant teaching and learning theory,the corresponding optimization strategy is proposed.This study found that there are great differences in teaching nature,teaching purpose,teaching content,teaching methods and students' ability requirements of physics in middle and high schools.At present,the main problems in the connection of middle and high schools include teaching materials and teachers.The problems in teaching materials mainly lie in the lack of continuity and consistency of concepts and laws of physics in junior and senior high schools and the jump of experimental courses.The problems of teachers mainly include that the senior high school teachers have less knowledge of junior high school physics textbooks,the teaching methods of senior high school physics teachers are not suitable and the senior high school physics teachers are not equipped enough.Finally,in view of these differences and problems,the author puts forward some Suggestions that teachers should study the teaching materials of middle schools to grasp the knowledge connection points,choose appropriate teaching methods based on students' cognitive level,cultivate students' correct learning methods and learning habits,and reasonably compile and use the teaching materials.Based on the new experimental textbook of junior and senior high school physics,this paper identifies the main problems in junior and senior high school physics teaching from the aspects of teaching materials,teachers and students,and proposes feasible optimization strategies from the aspects of teaching contents and methods,so as to provide feasible teaching suggestions for senior high school physics teachers.Finally,with the concept of friction as the teaching case,the paper carries out the optimization design of teaching cohesion in junior and senior high schools,and investigates the effect of teaching cohesion optimization through a questionnaire survey of students.The results show that the optimization strategy can play a good role in teaching cohesion,and can significantly reduce the learning difficulty of physics knowledge,and promote students to better grasp the concept and knowledge points of physics.This study can provide Suggestions and references for solving the problem of physics connection teaching in junior high school and senior high school,and guide students to successfully overcome the difficulties of physics connection in junior high school and senior high school. |
