Investigation And Research On High School Students' Mathematical Visual Imagination Literacy

With the ordinary high school mathematics curriculum standard(2017)issued,a new round of high school mathematics curriculum reform is in full swing.Oriented to train and improve students' mathematics literacy have raised a hot wave of mathematics education researches.Especially,the assessment of mathematical literacy is regarded as an important part of the high school curriculum reform.There for,more researches are needed.This paper is based on intuitive imagination,the knowledge of the three modules of “function and its application”,“vector and geometry” and “statistics and probability” in the textbook of high school mathematics in Beijing Normal University.Using literature review method,test method and other research methods to construct high school students' mathematical visual imagination literacy evaluation system:Establish a measurement framework,formulate bidirectional breakdowns of propositions,compile assessment tools,identify assessment targets,and process analytical assessment data.This paper analyzes the status quo of high school students' mathematical visual imagination literacy from both qualitative and quantitative perspectives,and then proposes some teaching suggestions to provide reference for the cultivation of high school students' intuitive imagination.The results of the survey show that:(1)the level of mathematics visual imagination of high school students in our province is at level two;(2)the level of geometric visual imagination of high school students is higher than the level of visual imagination of algebra;(3)the level of visual imagination of high school students is not affected by geography.
