Comparative Study Of Four Versions Of High School Mathematics Textbooks Published By People's Education Pres

With the development of the times,the new round of basic education curriculum reform has a more far-reaching impact.Teaching materials are the embodiment of curriculum standards and the learning materials that accord with students’ cognitive structure.The analysis and research of textbooks can help to study the educational,scientific and cultural undertakings of our country.Solid geometry in mathematics is a key part of textbooks,which plays an important role in cultivating students’ core literacy of mathematics and is representative of its research.It is necessary to make a comparative analysis of the 2019 textbook,which has been used by only a few classes of students.This study selects textbooks before and after the curriculum reform of basic education,takes the solid geometry part of the textbooks of 1983,2006,2007 and 2019 issued by People’s Education Society as the research object,and makes a comparison in the following two aspects:(1)Comparison of the overall structure,mainly including directory comparison,chapter introduction comparison,column setting comparison,expanded column comparison,chapter summary comparison;(2)The comparison of course content,mainly including the comparison of knowledge points,exercises and difficulty of course content.The findings are as follows :(1)the overall structure is more substantial,and the2019 textbook pays more attention to guiding teaching;(2)The integration of knowledge is gradually closer,and the 2019 edition pays more attention to the integrity;(3)Exercise setting is gradually optimized,and the 2019 textbook pays more attention to students’ all round development;(4)The difficulty of course content has been rationalized,and the2019 textbook pays more attention to inquiry based learning.Based on the results of analysis and research,this paper provides ideas for the compilation of textbooks :(1)it is suggested to select materials for the column of inquiry and discovery from the examples of life around them,which helps students to conduct modeling,diverges their thinking,and enables students with good foundation to selectively analyze and solve problems;(2)Chapter summary suggestions are divided into three parts: knowledge structure,review and reflection,and reference examples;(3)It is suggested to introduce the content of space vector in the chapter of solid geometry.
