By using the methods of qualitative description and quantitative description,this paper compared the compilation characteristics of “plane vector” content in three versions of high school mathematics textbooks in mainland China and Taiwan from the aspects of content structure,style column,content breadth,and depth.The People’s Education A version has a strong inquisitiveness;the Beijing Normal University version highlights the subject compatibility and the student subjectivity;and the Hanlin version emphasizes the mathematics knowledge intuitiveness and correlation.Thus,it is suggested that the construction and compilation of high school mathematics textbooks in China need to integrate and link the internal relationship between mathematical knowledge and the design and compilation of mathematics textbooks based on core literacy.
