| Along with globalization of economy and advent of knowledge-based economy era,the international talent in an increasingly competitive.In order to cultivate more competitive innovative talents on the international stage,the basic education of our country is constantly carrying out reform and innovation.In May 2017,the General High School Mathematics Curriculum Standard was officially published,which talks about mathematical modeling literacy.Although the new curriculum gives high evaluation and full attention to mathematical modeling,it is hoped that mathematical modeling can be truly implemented in high school mathematics class.However,due to the constraints and influences of various factors,it is understood that the mathematical modeling of most high schools is not optimistic,and both students and teachers lack the relevant resources and experience.Therefore,it has become a hot topic in the field of mathematics education to investigate the present situation of high school students’real mathematics modeling literacy and how to improve the high school students’modeling literacy.The author believes that mathematical modeling literacy includes not only mathematical modeling ability,but also mathematical modeling emotional attitude.Therefore,the author takes some senior one,senior two and senior three students of Taiyuan Foreign Language School as the research object,using literature analysis method,investigation method,interview method and other methods,the research tools are "2019 Mathematical Modeling Ability Test Volume "and "2019 Mathematical Modeling Emotional Attitude Questionnaire ",and takes "2019 Modeling Nutrition Division Standard" as the evaluation tool,combined with EXCEL and SPSS20.0 computer software to investigate the current situation of senior high school students’modeling literacy,and draw the following conclusions:(1))By collecting data,processing data and analyzing data,it is found that the average score of students is very low,the high score is few and the low score is especially high,which reflects the current situation that the modeling level of high school students is generally low.(2)Then the author discusses the differences of gender and grade in the modeling of high school students’mathematics from two dimensions:gender and grade.The results show that there are gender differences in high school students’mathematics modeling literacy,and the level of male students’mathematics modeling literacy is generally higher than that of female students.But by calculating the effect value,it is found that there is no significant difference in the statistical sense.Years in Senior Secondary Mathematics Modeling Grade difference,senior three students better than the level of mathematics modeling literacy,senior two students are better than senior one.But by calculating the effect value,it is found that there is no significant difference in the statistical sense.In view of the weak level of senior high school students’mathematics modeling,the author puts forward the teaching suggestion of "three three four".The three principles of teaching are subjectivity principle,autonomy principle and practicality principle.The three stages of teaching are basic,intermediate and advanced.teaching four strategies,including classifying and explaining modeling knowledge,carefully selecting modeling problems,focusing on optimizing modeling methods and strengthening training modeling exercises.Then the author introduces two practical teaching cases,one from the high school mathematics textbook,that is,the teaching design of exponential function based on the idea of mathematical modeling,and the other from the topic course of mathematical modeling,that is,based on mathematics Pineapple peeling under modeling ideas.Finally,the author also made a comprehensive reflection and prospect on the whole research process,hoping to help the future researchers and first-line math teachers. |
