Investigation And Research On The Support Of Logical Reasoning Literacy In Current High School Mathematics Textbooks

“Mathematics Curriculum Standards for Ordinary High Schools” issued in 2017,focused on the implementation of the core literacy of mathematics subject,and clearly pointed out that logical reasoning literacy is one of the six core literacy of mathematics subject.At present,people's Education Press has written high school mathematics textbooks under the guidance of the core literacy of mathematics subject.The extent to which the content of specific chapters in textbooks supports the development of students' logical reasoning literacy needs to be demonstrated by reliable data.This helps teachers to accurately grasp the content that help to cultivate logical reasoning in the textbooks,so as to better cultivate students' logical reasoning literacy.The main research methods used in this paper are literature research,questionnaire survey,quantitative analysis.Through the literature analysis method,the research background of this paper and the literature review related to this paper are determined,the main problems of this paper are clarified,and the related concepts of this paper are defined.Through the questionnaire survey,we learned the support of the five parts of each section of the textbook for the three levels(level one,level two,level three)and four aspects(situation and problems,knowledge and skills,thinking and expression,communication and reflection)of logical reasoning literacy.Through longitudinal analysis of the data,we obtained the support of each chapter in the textbook for the three levels and four aspects of logical reasoning literacy,and then we get the support of logical reasoning literacy in the whole textbook.Through horizontal analysis of the data,we obtained the support of logical reasoning literacy in each part of the textbook.This article analyzes and studies the relevant theories of textbooks and logical reasoning literacy,and compiled a questionnaire on the support of textbooks to logical reasoning literacy according to the classification criteria of logical reasoning literacy “Mathematics Curriculum Standards for Ordinary High Schools”.The questionnaire takes teachers as the respondent,investigates the support of the textbooks to logical reasoning literacy.Through in-depth analysis of the survey data,it is concluded that the whole textbook has a support level for the implementation of the four aspects of logical reasoning literacy.That is,the compilation of textbook reaches the level of the college entrance examination.Aiming at the results obtained from the research,we put forward basic requirements for teachers to use new textbooks to implement logical reasoning literacy: to understand the changes in the content of the textbooks,to understand the degree to which the textbooks implement the core literacy of students in mathematics,and to carry out teaching activities based on the textbooks.Specific suggestions for the use of textbooks: pay attention to the teaching of commonly used logical terms,pay attention to the teaching of mathematical formulas,pay attention to the effectiveness of student activities,pay attention to the use of exercises.
