Research On The Support Of Intuitive Imagination Literacy In Current High School Mathematics Textbooks

With the advancement and development of mathematical core literacy,mathematics education scholars and many front-line teachers are focusing on how to better implement mathematical core literacy in teaching.In view of this,many scholars and teachers have put forward more strategies and suggestions for implementing intuitive imagination in textbook compilation,but they lack the research to guide front-line teachers on how to use the current mathematical teaching textbooks to cultivate students' intuitive imagination.Therefore,we need to understand the level of support that the current high school mathematics textbooks use to implement the four aspects of intuitive imagination.Through research,objectively describe the support of teaching materials to implement visual imagination,so as to provide teachers with a scientific theoretical reference and data support for better re-development of teaching textbooks to implement visual imagination.This article first summarizes the related literature on the implementation of mathematical core literacy,the implementation of intuitive imagination literacy,and the implementation of intuitive imagination in textbooks.Then divide the textbook according to the theory of the textbook structure and the specific situation of the textbook.According to the division of three levels and four aspects of intuitive imagination literacy in the <General Senior High School Mathematics Curriculum Standard(2017 Edition)>,comprehensively compile a questionnaire to collect teachers' views on the degree of support for the implementation of intuitive imagination in the current high school mathematics textbooks.Finally,I get the support of the current high school mathematics textbooks for implementing intuitive imagination.After collecting and processing data,use Excel software to statistically analyze the support of visual imagination literacy in teaching materials,and obtain the degree of support for visual imagination literacy in each part and each chapter of textbook.Among the more obvious results are:(1)In longitudinal analysis,the fifth chapter of the textbook has the highest degree of support for the implementation of intuitive imagination.The first and second chapters of the textbook mainly support the level one of the four aspects of intuitive imagination literacy.The third,fourth,and fifth chapters of the textbook mainly support level two of the four aspects of intuitive imagination literacy.(2)From the perspective of horizontal analysis,the examples given in the textbook and the design of the after-school exercises have the highest support for the implementation of intuitive imagination.The knowledge presentation part and the proposition given part of the textbook are mainly the highest support for the level one of the four aspects of intuitive imagination literacy.In the textbook,the student activity arrangement part,example problem part,and after-school exercise design part are mainly the highest support for the level two of the four aspects of intuitive imagination literacy.On this basis,suggestions are put forward for teachers to use teaching materials to cultivate students' intuitive imagination:(1)Teachers need to identify the location of the contents of textbooks.(2)Teachers need to increase the focus of knowledge presentation and proposition derivation to implement intuitive imagination,which mainly includes two parts: the supplementary visual representation form of knowledge presentation and the content visualization process of expanding the proposition derivation.(3)Teachers need to screen the content of student activities in the textbook.(4)Teachers need adequate textbook development examples to give some potential value.(5)Teachers need to integrate the content of the after-school exercise design section.
