Investigation And Research On Mathematics Operation Literacy Support In Current Senior Middle School Mathematics Textbooks

The Standards for General Senior High School Mathematics Curriculum(2017 Edition)focuses on the implementation of core literacy in mathematics,and clearly states that core literacy in mathematics includes: mathematical abstract literacy,logical reasoning literacy,mathematical modeling literacy,intuitive imagination literacy,mathematical operation literacy and data analysis literacy.Among them,mathematical operation literacy is the most basic and critical one.At present,People's Education Press has compiled high school mathematics textbooks with the core literacy of mathematics as the guide.The reliable data is needed to explain the degree of support for the newly developed textbooks to cultivate students 'mathematical operation literacy,so as to help teachers accurately grasp the content of the textbooks that helps to cultivate mathematical operation literacy,and then better cultivate students' mathematical operation literacy.The main research methods used in this paper are literature research method,questionnaire survey method and statistical analysis method.Through the literature analysis method,the research background of this article and the literature review related to this thesis were identified,the main issues of this article were clarified,the related concepts of this article were defined,and the questionnaire was compiled with the help of literature data.Through the questionnaire survey method,using the first volume of the pedagogical edition as the material,by investigating the firstline mathematics teachers in high school,I learned the support of the five parts of the textbook for the three levels and four aspects of mathematical literacy.Through statistical analysis,get each chapter of the textbook supports three levels and four aspects of mathematical literacy,and then get the entire textbook's support situation.of the mathematical operation literacy and each part of the textbook's support situation of the mathematical operation literacy.Through in-depth analysis of the results of the investigation,it is concluded that the entire textbook has support for the four aspects of implementing mathematical operation literacy.Most teachers believe that the support level has reached level two.Examples of textbooks support 9 aspects of implementing mathematical literacy.Knowledge presentation of textbooks support 11 aspects of implementing mathematical literacy.Knowledge presentation of textbooks,student activity arrangements,and after-school exercise design support 9 aspects of implementing mathematical literacy.Aiming at the results obtained from the research,the teachers have put forward basic requirements for implementing mathematical literacy in new teaching materials: 1.Focus on the mathematical operation process in knowledge generation.2.Strengthen the understanding of mathematical concepts and improve students' mathematical literacy.3.Infiltrate mathematical operations in student activities.4.Make full use of textbook exercises to implement mathematical literacy.Based on the basic requirements,teaching suggestions for the five chapters in the textbook are given according to chapters.
