Analysis Of Textbooks Based On "Macro-identification And Micro-analysis"

The cultivation of key competencies has become the focus of education all over the world.Macro-identification and micro-analysis,Macro-identification and micro-analysis is one of the five essential elements of chemistry key competencies,it is also the most important discipline concept and observational perspective of chemistry.Textbooks are the breakthrough and important medium for implementing educational goals and cultivating students' key competencies.Therefore,studying the distribution and level of "macro-identification and micro-analysis" in high school chemistry textbooks are of great significance to promote the development of students' key competencies.On the basis of combing the domestic and foreign related research results,regarding the textbook of senior high school chemistry published by PEP as the research object,and basing on the connotation,curriculum objective and level division of " macro-identification and micro-analysis " literacy in the "General High School Chemistry Curriculum Standards(2017)",The paper makes a statistical analysis on the distribution and level composition of this literacy in senior high school chemistry textbooks.Based on this,the author puts forward the teaching suggestions for cultivating the students "macro-identification and micro-analysis" literacy.Through statistics and analysis,the research results obtained in this paper are as follows:(1)Most of the contents of high school chemistry textbooks contain “macro-identification and micro-analysis” literacy.(2)Each book has different emphasis on the literacy.The content that embodies "macro-identification and micro-analysis" literacy in compulsory 1 and Elective 5 has the most,Elective 3 are in middle and Elective 4 is the least.(3)The literacy of "macro-identification and micro-analysis" in the high school chemistry textbook of the PEP is mainly reflected in the level 1 and level 2.(4)The level distribution of the literacy in the high school chemistry textbook of the PEP is scientific,From compulsory courses to elective courses,the contents of level 3 and level 4 are gradually increasing.Finally,through the analysis of textbooks and the study of related theories,the author further proposes the following teaching strategies :(1)Attach importance to the cultivation of macro-micro combined thinking.(2)pay attention to the developmental function of this literacy in the content of elemental compounds and organic compounds.(3)From whole to parts,rationally design teaching objectives and literacy goals.(4)Pay attention to the foundation of literacy teaching.At the same time,the author makes suggestions for the revision of the new textbook for reference.
