Investigation And Research On The Current Situation Of Mathematical Modeling Literacy Of Senior Two Students

Mathematical modeling literacy is a creative thinking activity and a carrier to train innovative talents,it not only promotes the development of other disciplines,but also cultivate students' ability to solve problems and meet social challenges.With the development of mathematics curriculum reform in China,mathematic modeling literacy has gradually become the research content of all countries,However,many surveys show that the overall quality of mathematics modeling is not very satisfactory in China's middle schoo;sthdents.,Therefore,understanding the level of students' mathematical modeling,influencing factors and developing strategies for students' mathematical modeling literacy have become the focus of research.understanding students 'mathematics modeling level,influencing factors,and how to develop students' mathematical modeling literacy has become a research hot spot.Based on the above background,this paper selects sophomore students as the research object,and adops the methods of literature,investigation,statistics and interview to study the quality of mathematical modeling of senior middle school students.First,it summarizes the concept,structural elements and level division of mathematical modeling literacy through literature review on mathematical core literacy and mathematical modeling literacy at home and abroad..Secondly,on the basis of referring to the framework of mathematics literacy assessment,we constructed the evaluation framework of mathematical modeling literacy from four dimensions: modeling knowledge,modeling situation,modeling ability and modeling cognition,and investigated the level of mathematical modeling literacy of senior two students..Finally,using SPSS20 and EXCEL software to analyze the distribution of students' mathematical modeling literacy level,The research questions are mainly divided into the following three aspects:(1)constructing a framework for evaluating the quality of mathematical modeling,and compiling test volumes and questionnaires based on these models.(2)analyzing the current status of students' mathematical modeling literacy level through the test results;(3)giving training strategies according to the analysis results and influencing factors,Through the analysis of the test volume,we can draw the conclusion that the students' mathematical modeling literacy is as follows:(1)the overall level of students' mathematical modeling literacy is relatively low,that is,they can understand the knowledge they have learned,but there are some problems in the actual transformation and application.(2)Gender and classes of arts and sciences have significant differences in students' mathematical modeling literacy.(3)The student's modeling literacy level is related to the usual test scores,.Through the questionnaire,this paper studies the relevant factors that affect students' mathematical modeling literacy from the four aspects,namely,the cognitive structure of mathematical cognition,mathematical modeling emotion,self-monitoring,and teacher's influence,and finds the following problems:.(1)Compared with other factors,teachers have the greatest influence on students;(2)There is a large gap between students in the understanding of modeling,and little is known about modeling in textbooks and examinations.3 Students have high expectations for mathematical modeling to improve math scores,but their ability toexamine and migrat mathematical models is rather poor.Combined with the findings of the influencing factors,specific teaching case analysis was given,andput forward development strategies from three aspects: teachers,college entrance examination and classroom teaching:(1)improve teachers' modeling ability;2 clarify the mathematical modeling content in the college entrance examination;3 Create modeling-oriented mathematics classes.
