A Comparative Study About Analogies In Five Versions Of Physics Textbooks In High School

In the context of cultivating high-quality,modern talents,scientific literacy is increasingly important in today's society.As a representative of natural science,physics involves many scientific thinking.Analogy is not only used by many scientists,but also often used in physics textbooks to help students learn new concepts using known knowledge.In order to understand the differences in the content of analogies in different versions of high school physics textbooks,and to help front-line teachers obtain abundant analog resources,and scientifically treat the existence of analogies in textbooks,this article counts and analyzes the five editions(Personal Education Edition,Luke Edition,Textbook Edition,Shanghai Education Edition,Guangdong Education Edition)The use of analogies in physics textbooks.This research has a certain significance in promoting teachers' deep understanding of high school physics textbooks,awakening the awareness of front-line teachers' analog thinking ability training,and helping teachers to re-look at the analog content in textbooks from the perspective of core literacy.This article is modified on the analogy classification framework of Thiele and Treagust to establish a new analogy classification framework.Scan and count analogies according to the framework,first quantify and then qualitative analysis.The framework is mainly divided into three parts:macro analysis,micro analysis and explanatory discourse analysis.The main conclusions are as follows:(1)Textbooks emphasize the application of analogy,but they are not evenly distributed in each module.(2)Most analogies come from this discipline,which is conducive to constructing the structure of physical knowledge.(3)Some textbooks have simple analogies and need to be supplemented by frontline teachers.(4)The introduction of analogical cognitive strategies is not sufficient,which is not conducive to the cultivation of students' scientific thinking.(5)There are fewer restrictions on the use of analogies,preventing students from abusing analogies.Based on the conclusion,the author makes several suggestions to textbook writers and front-line teachers.Suggestions for textbook writers:(1)Textbooks should clarify and highlight the analogy method;(2)The simple analogy in textbooks is more suitable for the teaching of lower grades.For high school students,more difficult analogies can be added to carry out in-depth analogies.(3)on the basis of reasonable text arrangement,try to increase the explanation of analogues;(4)Increase the use of analogy and limit the explanation to avoid excessive analogy.Suggestions for teachers:(1)Teachers should improve their awareness of using analogy;(2)teaching to increase the depth of analogy,improve the students' ability of analogy;(3)attach importance to the analogues of the subject and form the framework of knowledge system;(4)Teachers refer to multi-edition textbooks in their teaching process.
