A Comparative Study Of The Old And New Versions Textbooks Of People's Education Press For High School Mathematics

As an important carrier of curriculum standard,mathematics teaching material is a powerful basis for teachers and students to develop mathematics teaching.Ordinary High School Mathematics Curriculum Standard(2017)emphasized that " high school mathematics curriculum based on students' development,implement the fundamental task of cultivating people by virtue " " enhance the core quality of mathematics ",under the background of subject core quality oriented,it is urgent to solve the problems of how to interpret mathematics teaching materials and how to use mathematics teaching materials scientifically and normatively for education workers.This paper takes the content of "plane vector" as the research object,makes a comparative analysis of two sets of high school mathematics textbooks published by people's education society in 2007 and 2019,and on the basis of in-depth interpretation of the corresponding curriculum standards,uses comparative analysis,content analysis,statistical analysis and other methods,first around the chapter design characteristics of the new and old textbooks In order to have an overall grasp of the plane vector content and reach an overall understanding of the content structure and arrangement of the textbook.Next,the paper compares the content presentation,example exercise configuration,difficulty characteristics and mathematical culture characteristics of the two editions of textbooks,so as to understand the plane vector content more thoroughly and excavate the characteristics and value of the new textbooks more comprehensively:The new textbook shows the "student-oriented" "learning material view",which provides more learning opportunities for students.The new teaching materials attach importance to the relationship between whole and level,so that students can deepen their overall understanding of knowledge group.The new textbooks focus on showing the formation and development process of knowledge and promoting students' meaningful learning.The new textbook highlights the infiltration of mathematical culture in vector content,and highlights the process of mathematical modeling.On the basis of thinking about the characteristics of the new textbook,the author puts forward some strategies and suggestions for the teaching and learning of plane vector content.Firstly,we should understand the vector content from the perspectives of physics,algebra,geometry and so on,and fully show the characteristics of the fusion of vector "shape" and "number",develop core literacy in mathematics.Secondly,we should pay attention to the essence of mining vector operation,and focus on the analysis of vector operation and number operation by analogy,promote the development of mathematical thinking.Finally,students should experience the formation and development of various contents,and reflect the mathematical research methods.
