A Comparative Study On The Content Setting Of Physics Textbooks Between China And The United States ——Taking The Part Of Gravitation As An Example

Teaching materials are the key bridge between teachers and students,and play an irreplaceable role in teaching practice.Through teaching materials,students can view history and the world under the guidance of teachers,and acquire new ideas and new knowledge.Through the comparative study of teaching materials,we can find the educational ideas and principles of countries with different systems,and find their specific requirements and specifications for personnel training.This paper makes a comparative study of the teaching materials of our country and those of developed countries,explores the presentation ways of other countries under the same knowledge system,refers to the treatment methods of the teaching materials of other countries,and summarizes the advantages and disadvantages of the current teaching materials of our country.broaden the teaching ideas of front-line physics teachers in our country,so as to promote the development of basic education practice in our country.Through the comparative analysis of the curriculum standard,the compilation basis of high school physics textbooks in China and the United States,from the five aspects of basic curriculum philosophy,curriculum objectives,curriculum structure,teaching suggestions and evaluation suggestions,it is found that the basic curriculum philosophy of the two countries is similar,the United States pays more attention to the cultivation of students' subjective initiative in curriculum objectives,and the arrangement of learning content in curriculum structure is basically the same.In the part of teaching suggestions,the United States pays more attention to the dominant position of students,and in the aspect of evaluation suggestions,the curriculum standards of both countries emphasize comprehensive evaluation.On the basis of comparing the curriculum standards of the two countries,this paper makes a comparative study on the setting of the overall columns in the textbooks of the two countries,and on this basis,analyzes in detail the setting of the columns in the part of gravitation in the textbooks of the two countries.It is found that the textbook of our country pays less attention to the experiment than the United States,and we can still use it for reference in the setting of some columns.Taking the part of gravity as a starting point,a comparative study is made on the selection and organizational structure of knowledge content,the setting of the content of the history of science and the setting of example exercises in the mainstream physics textbooks of the two countries.It is found that the scope of content selection of American teaching materials is more extensive.In the part of setting the content of the history of science,the two countries' textbooks should balance the distribution of the content of the history of science.The number of exercises in Chinese textbooks is small,and the location and type are single.There is a big deficiency.Through the analysis of the above research contents,the following suggestions are put forward for front-line physics teachers in terms of teaching methods,teaching contents and teaching suggestions: paying attention to strengthening the connection between disciplines,helping students to summarize knowledge,teaching according to the actual situation of students,strengthening the teaching of examples and supplementing the frontier content of discipline development.The following suggestions are put forward for textbook compilers in terms of column setting,course content,subject connection,and content of history of science: adding target content at the beginning of chapters,adding summary modules in each chapter,adding online learning resources,paying attention to the presentation of inter-disciplinary connection content,optimizing the position allocation of content of history of science,and adding practical columns.Through specific and directional suggestions,we hope to promote the update and optimization of the relevant parts of domestic physics textbooks,improve the teaching practice of front-line physics teachers,and improve teaching efficiency.
