Investigation On The Status Quo Of High School Students' Intuitive Imagination Literacy And Research On Improvement Strategies

With the release of "General High School Mathematics Curriculum Standard" in2017,intuitive imagination literacy was first put forward,as one of the core literacy of six major mathematics disciplines,its importance is self-evident.In mathematics teaching,intuitive imagination can help students perceive the movement changes of things,understand problems,and solve problems.And how is the intuitive imagination quality of high school students now? How to improve the intuitive imagination literacy of high school students on this basis? In view of this,this paper uses testing and interview methods for deep research.This study adopts methods like literature analysis,test,interview,data analysis,to determine the evaluation framework from the characterization form,content dimension,horizontal dimensions,to investigate the visual imagination of high school students,and to understand the views of teachers through interviews,finally analyze the problems and reasons behind the current situation,and give targeted teaching strategies.The main conclusions of this study are as follows: on the whole,the visual imagination performance of students is general,and the overall situation of the third grade is better than that of the senior second grade.Microscopic view:(1)The scoring rate of the second grade and the third grade on a two-dimensional problem is more than 50%,but the scoring rate of the second grade on a three-dimensional problem is only 33.63%,with a poor performance.Both grades score over 60% on static questions.The scoring rate for the second grade only 45.15%on the dynamic questions,which is a poor performance.The scoring rate of the second grade in the system characterization is only 38.78%.The scoring rate for the senior third grade in the inter-system characterization is 58.34%.Both need to be further improved.(2)The scoring rate of the second grade and third grade is between 45% and 65% in plane analysis geometry,three-dimensional geometry,function and application content dimensions,and the performance is average.However,the scoring rate of the two grades is about 40% in the probability and statistical dimensions.Relatively it is a poor performance and needs to be improved.(3)The scoring rate of the second and third grade exceed 60% at the intuitive level,with a good performance.,nearly 50% at the analysis level,with a general performance,about 30% at the inquiry level,with a poor performance.On the whole,high school students perform well at a low level and poorly at a high level,which shows that high school students ' ability to explore and analyze is still insufficient.Based on the analysis of the present situation,this study proposes five promotion strategies:(1)focus on the requirements of topic drawing,cultivate independent drawing ability;(2)strengthen the training of unconventional high-level geometric topics,expand spatial imagination thinking;(3)strengthen the construction and interpretation skills in probability and statistics,improve the adaptability of the data era;(4)appropriately use information technology teaching,strengthen the cultivation of geometric intuition;(5)accurately transform number and shape,permeate good ideological methods.
