The Study Of The Teaching Practice Of "Interaction" Based On The Comparison Of Teaching Materials

At the key nodes of new curriculum standards and replacement of new and old textbooks,domestic physics textbooks still implement the system of "one standard and more books".Under this background,teachers research and comparative textbooks conduct in-depth research and analysis of physics textbooks,which makes the use,development and promotion of physics teaching development of new textbooks far-reaching significance.Now the new version of the textbook has been published.After reading the new version of the textbook,we find that the new textbook has changed more than the content of the old textbook.This study chooses the content of "interaction" as the research topic,and chooses the human education version published in 2019,the Cantonese version,the human education edition published in 2010,and the four editions of the Guangdong education version as the research object for vertical and horizontal comparison and analysis.First of all,the relevant literature on the analysis of physics textbooks and the comparison of physics textbooks are reviewed and summarized to understand the current research situation of the two.Through the literature review,it is found that in the current research situation of physical textbook analysis,it is found that the textbook analysis theory and method are richer about the overall analysis of textbooks,chapter analysis,etc.,and after the analysis,the conclusions are also theoretical suggestions and operability suggestions such as teaching design.In the current situation of comparative research of physics textbooks,it is found that the comparison of textbooks,both at home and abroad,pays attention to the comparison of micro-contents of textbooks.Some researchers will put forward specific plans to optimize physics teaching or corresponding textbook reform and teaching suggestions based on the research results,but give excellent suggestions on how to compare textbooks.The process and strategy of chemical physics teaching education to break through important physics teaching difficulties,and further in-depth research is needed.At the same time,in the process of literature review,we understand the method of comparing the analysis of physical textbooks with the physics textbook,and provide a methodological basis for the next research subject.Secondly,after reading the literature,a characteristic analysis framework for the compilation of the content of the "interaction" of the four editions of textbooks is formed,and compared and analyzed from the four dimensions of the old and new curriculum standards,the selection of knowledge content,the presentation of knowledge content,and the concept of physics teaching.After comparison,it is found that while adhering to the commonality of the physics curriculum standards,different versions of textbooks have their obvious advantages and defects(comparatively speaking),and at the same time,they are sure about the changes of the content of the "interaction" of the four editions of textbooks.Thirdly,from the comparative analysis of the characteristics of the content writing of the"interaction" of the fourth edition of the textbook,it is found that the writing content of "elastic force","decomposition of force" and "co-point force balance" are very different.Therefore,the three of them are selected as the next case study objects.First,the content of the case is compared and analyzed,and a certain amount is obtained in the process.Think about and discuss it to a certain extent.Finally,synthesize the above-mentioned preliminary teaching design results,and apply the preliminary results of the research to the teaching design results in practice to form operability with class(1)and(2),grade one of Yinchuan NO.9 high school as practical objects,and carry out case evaluation.I hope that through the above practice,on the basis of textbook comparison,we will choose content with great differences in writing methods and difficult to learn,carry out teaching design and case studies based on textbook comparison,creatively use the results of textbook comparison,integrate textbook resources,and put forward teaching plans to optimize physics teaching in combination with teaching physics.In order to improve the problem of physics teaching and improve the compilation of teaching materials.
