| With the pace of The Times,China’s education reform is also in full swing.In the past eight years,the ministry of education has issued the curriculum standard of common senior high school mathematics(2017 edition)(hereinafter referred to as the new curriculum standard).Before this,Chinese senior high school mathematics textbooks were compiled and revised according to the curriculum standard of common senior high school mathematics(experimental edition)(hereinafter referred to as the old curriculum standard).On the basis of the old curriculum standard,the new curriculum standard developed the "double-base" to "four-base",expanded the "three-ability" to "four-ability",and transformed from "five abilities" to "the core qualities of six mathematics disciplines".High school mathematics teaching material is the embodiment of the curriculum requirements and the important carrier,with new lesson mark promulgated has made a comprehensive revision,and gradually put into use throughout the country.To reasonably use the new teaching material,exert its maximum utility,with scientific means to study the new teaching material,analysis of the writing ideas,explore its in which changes made on the basis of the old teaching materials.This article selects the high school mathematics taught A version 2007 required five chapter iii and chapter 2019)required A second as the research object,both as A compulsory part of high school mathematics content of inequality,using literature study,comparative study method,interview method and other research methods,in virtue of professor Bao Jian Sheng example problem difficulty model and the explanation structure model(ISM)and other tools,for domestic and foreign research achievements of the existing teaching material first has carried on the literature review,from the curriculum standard,writing style,the knowledge structure and sample problem sets four aspects has carried on the detailed analysis and comparative study,the final interview for first-line teachers,To understand the use of the new textbook and its suggestions.Based on the above study,the design of the new teaching material more human,considering the students’ cognitive basis and cognitive psychology,prepare new knowledge to solve the problem of primary and high cohesion,optimization of chapter introduction,columns,summary,cut hard knowledge,adjust the knowledge presentation sequence,perfecting the sample set,refine the problem level,these changes are conform to the new standard of "based on students’ development",penetrating the core mathematics literacy.Based on the above research conclusions,the author puts forward teaching suggestions and designs a teaching case for readers’ reference according to the characteristics of new textbooks.It is hoped that the quantitative research on the inequality part and the teaching suggestions on the inequality part of the new teaching materials based on the current situation can provide teaching ideas and reference value for the teaching of front-line teachers,so as to contribute to the cultivation of excellent and high-quality talents in China. |
