A Comparative Study On The Content Related To Analogy In High School Physics Textbooks

Analogy is a kind of reasoning form in logic,different from general to individual deductive reasoning and from individual to general inductive reasoning.Analogical reasoning is a logical thinking method from individual to individual,and it is a probable reasoning process mainly by means of similarity between different things.Analogy reasoning is simpler than both of the two,which is a kind of thinking form that middle school students can easily accept and often use.Physics is closely related to analogical reasoning.The teaching process of physics is also the process of guiding students to carry out scientific exploration and scientific discovery.Physics textbooks contain a large number of analogical reasoning content,which is related to the cultivation of the core literacy of various physical disciplines of teenagers.This study selects two high school physics textbooks published by people's education press in 2004 and 2019 as research samples.Based on a large number of literature research on Analogy Teaching of physics,the paper comprehensively improves the analysis and verification table of analogical reasoning content in science textbooks.First,the paper uses this checklist to compare and analyze the analogical reasoning content in the old and new high school physics textbooks.On this basis,combined with the cognitive development theory and constructivism theory,the paper makes a micro analysis of the contents of these analogical reasoning in the presentation,mapping degree and using methods.The following conclusions are drawn through comparative study(1)The content of analogical reasoning in the old and new textbooks is uneven,and the overall content is too abstract,so analogy method can not play its biggest role in teaching.(2)The two textbooks show the interdisciplinary knowledge well,and analogy between different disciplines can help students to achieve the knowledge fusion.(3)The textbook of 2004 edition pays more attention to the cultivation of divergent thinking,while the 2019 edition focuses on the transfer of thinking methods and knowledge framework among the plates,and emphasizes the internal links of disciplines.(4)The textbook of 2004 edition shows more comprehensive use methods of analogy,and pays more attention to the logical combing of analogy process.(5)The textbook of 2019 edition attaches more importance to teaching methods.The new textbook explicitly expounds the analogy,a scientific reasoning method,and outlines the boundary of its use.On this basis,the text from two dimensions,for the physical textbook writers and high school physics teachers to put forward some suggestions.
