Research On The Level Of Intuitive Imagination Literacy Of High School Students

Intuitive imagination literacy is one of the core literacy of mathematics.It plays an important role in the core literacy system of the six major mathematics disciplines.It has important theoretical and practical value to study its development level and influencing factors.This paper focuses on the two issues of "What is the current situation of the level of intuitive imagination literacy in high school students?" and " What are the factors that affect the level of intuitive imagination literacy of senior high school students?".Referring to the four performances and level division of intuitive imagination literacy in the mathematics curriculum standard of senior high school(2017 Edition),this paper constructs the evaluation framework of intuitive imagination literacy level.On this basis,the evaluation formula of intuitive imagination literacy is established by Delphi expert survey method,and the level of intuitive imagination literacy of students is quantitatively analyzed.A total of 470 senior high school students and 8 first-line mathematics teachers from five regions(Jiayuguan,Zhangye,Dingxi,Lanzhou and Gannan)in Gansu Province were selected as the research objects.The current situation and influencing factors of intuitive imagination literacy level of senior high school students were studied by literature research and survey methods(including tests,questionnaires and interviews).The results are as follows:There are eight conclusions in the aspect of literacy level: the overall level of intuitive imagination literacy of senior high school students(hereinafter referred to as students)is above the middle level;the ability level of intuitive imagination literacy of students in different performance is quite different;Students have different levels of mastery of different knowledge modules and poor practical application ability;students from different backgrounds have different intuitive imagination literacy and related ability levels,but each has its own advantages;There are great differences in students' literacy levels in different residential areas;the ability of instant extraction of boys' intuitive imagination literacy is higher than that of girls;students can take into account the development of visual imagination literacy in many aspects of performance ability in mathematics learning;the highest correlation between the level test score rate of geometry and algebra module and the usual performance.The influencing factors are as follows: students' own factors are the key factors influencing the development level of intuitive imagination literacy;family is the main external factor affecting the development level of students' intuitive imagination literacy;teachers are also an important factor affecting the development level of students' intuitive imagination,but the effect is not significant.Based on this,the following seven suggestions are put forward: Establish a positive view of geometry,and correctly understand the intuitive imagination;cultivate the learning interest of intuitive imagination,and improve the sensitivity of geometric intuition and spatial imagination;find appropriate learning methods to improve the learning efficiency of intuitive imagination literacy;strengthen the teaching of relevant knowledge of intuitive imagination literacy to coordinate the development of students' intuitive imagination literacy;pay attention to the effectiveness of multimedia use and the development of exploratory activities to help develop students' intuitive imagination literacy;encourage parents to participate in students' learning to help students develop intuitive imagination literacy;pay attention to the effective combination of family education and school education,and work together to develop students' intuitive imagination literacy.
