The Construction Of The Evaluation Model Of High School Students' Visual Imagination Quality

From the perspective of the development of mathematics curriculum,geometry is the first subject that people study in the form of curriculum,and geometry teaching has been given high attention in China.The importance of "intuition" is more obvious after the core quality of "intuitive imagination" is put forward in the general high school mathematics curriculum standard(2017 Edition).More and more scholars focus on the investigation and research of the current situation of geometric intuition and spatial imagination of students in compulsory education stage,or the investigation of the current situation of high school students' intuitive imagination literacy,and pay less attention to the evaluation of high school students' intuitive imagination literacy.Therefore,it is necessary to construct the evaluation model of high school students' intuitive imagination literacy.This study refers to the existing ideas and methods of the evaluation model construction in the field of education research,uses the literature method to sort out the relevant literature,combines the curriculum standards and the content of the intuitive imagination of high school mathematics teaching materials,initially formulates the evaluation index system of the intuitive imagination literacy of high school students,and based on this,prepares the student test paper.169 junior high school students in Yunnan and Sichuan were selected as the objects of investigation.The evaluation index system was modified by exploratory factor analysis.Three first level indexes and 11 second level indexes were obtained.Through the preparation of teachers' questionnaire and the use of questionnaire star platform to investigate the experts and scholars in the country and the mathematics teachers in senior high school,the results of confirmatory factor analysis show that the model is reasonable and highly adaptable to the data,and then use AHP to determine the weight of indicators at all levels,and construct the evaluation model of intuitive imagination literacy of senior high school students as follows:Y=0.26A+0.33B+0.41 C.In order to reflect the application of the evaluation model,the students who participated in the test were evaluated,and it was found that the students' intuitive imagination literacy was at a low level as a whole Quantitative relation,using graphics to express the idea of solving problems and building an intuitive model of mathematical problems are the observation points with low scoring rate in intuitive imagination literacy.Teachers should pay attention to them in daily teaching.At the same time,from the perspective of the development of test tools and the preparation of test questions,it can also be shown that the evaluation model has strong applicability and operability.
