Application Of Similarity Principle In Middle School Physics Teaching

Similarity is the manifestation of various associations between objective things.There are similar physical movements and similar philosophies in the objective world.Similarity world in the phenomena of similar to the research in the field of nature,society and thinking is similar to the widespread movement,similar to contact,similar to create law theory.This paper is divided into the following five parts:The first part is the introduction,which introduces the background,main points and current situation of the similarity principle,and analyzes the significance of the similarity principle.The second part is the theoretical basis,it expounds the universality of similarity in the development of physics,in modern scientific theory,in physics and in human thought and analyzes the relationship between similarity principle and middle school physics teaching and its guiding significance to illustrate the feasibility of similarity principle in physics teaching.The third part is based on the similarity principle of junior middle school physics teaching principle and teaching method discussion.Together with the present situation of the region's education teaching,with similarity theory as a starting point,puts forward three kinds of similar physical teaching method,were similar analogy method,similar reasoning method and similar analogy method,and based on this to build three kinds of teaching methods and examples.The fourth part is the teaching practice research part,on the basis of similarity principle to explore,in combination with the practical situation of the corresponding teaching design and teaching,some private junior high school teaching practice exploration in the Shanghai area.The results show that the physics teaching under the guidance of similarity principle is effective,and the students' physical achievements have been improved obviously,but the students' interest in learning has not improved significantly.The fifth part is the research result and prospect.The conclusions of this study are summarized and combined with the practical experience,the deficiencies of this study are summarized and reflected,and the research prospect is put forward.The innovation point of the study is to develop a novel and effective teachingmethod based on the similarity of physics curriculum and the characteristics of students' thinking(Based on similar information blocks).Firstly,there are few physical teaching practices based on similarity principle,and the similarity principle is less studied in junior middle school.Secondly,the application of similarity principle is operable,which guarantees the diversity of teaching to some extent.Third,similarity principle is to explore how the human mind in accordance with the principle of similar activities in the objective world,help to promote students' brain was similar in the emergence and development of yuan group,cultivate students' innovative thinking,can help students better grasp the physical theory system,learning to learn.
