A Survey Of The Core Accomplishments Of High School Students' Visual Imagination

The core accomplishment of mathematics refers to the necessary character and key ability of the students in the process of acquiring the knowledge of mathematics,which is suitable for the lifelong development of the individual and adapts to the development of the society.At present,the revision of high school mathematics curriculum standard is being carried out in a close and orderly way,and the series contents,such as how to train the students ' core quality of mathematics,how to integrate the contents of the core quality of mathematics into the teaching and the innovative teaching methods,will be the important content of the implementation of the At present,the research on the core accomplishment of our students ' intuitive imagination is very scarce,so it is very important to know the current situation of the students ' visual imagination.Attaching importance to the cultivation of students ' visual imagination in mathematics teaching activities can help students improve their ability to use space and figure to analyze problem solving,form the habit of using graphics to think problems and use graphs to carry out corresponding reasoning and argumentation,and improve students ' ability of combining numbers and shapes.This study focuses on the visual image core accomplishment proposed in the revision of curriculum standard,and carries out relevant research on visual imagination in high school students.First of all,through the relevant literature to determine the visual image of the core quality of the connotation and requirements,and from the space imagination,the geometrical intuition,the combination of the number shape three aspects to the visual imagination core accomplishment carries on the Content Dimension division,each dimension according to 2017 edition "high school curriculum standard" to the core accomplishment level division and the Lianping core accomplishment theory frame(knowledge understanding,Knowledge transfer and knowledge innovation are divided into three levels,in order to understand the current ability of students ' intuitive imagination through test survey.Combined with the analysis of data statistic results,the results show that:(1)It is found that the overall level of visual imagination of high school students is lower;(2)There are differences in Gao Zhengwen Science in Visual imagination,and science students are superior to liberal arts students;(3)There are significant differences between male and female students in visual imagination core literacy And the boys are slightly stronger than the girls;(4)High school students in different grades in the visual image of the core quality of the significant differences,and the senior three in the visual image of the performance of higher than the student;and finally put forward some teaching suggestions on the visual imagination.
