Investigation Analysis And Case Design Of Junior High School Students' Mathematical Modeling Literacy

Mathematics originated from application.For the development of mathematics and applied mathematics and the role of mathematics in the development of human beings,some domestic education experts and mathematics educators have proposed to pay attention to the cultivation of mathematics application ability.The "Basic High School Mathematics Curriculum Standards(2017 Edition)" proposes six core mathematics literacy(including mathematical abstraction,logical reasoning,mathematical modeling,visual imaging,mathematical operations,and data analysis).Among them,mathematical modeling is the real world.The actual problem is transformed into mathematics-related problems,and then the mathematical model is established to solve and test the application of the model.Mathematical modeling literacy as a combination of theory and practice,builds a bridge between mathematics and the external world,is an important form of mathematical application.After reading a large number of references and actual interviews,it is found that the current mathematical modeling literacy is not highly integrated into mathematics teaching.In order to further understand the development of mathematical modeling literacy,three aspects of investigations are made.Understand the current situation of mathematics modeling literacy of junior high school students and their experience in mathematics modeling literacy in the classroom.It is initially known that the level of mathematical modeling of the students surveyed is at a medium-to-high level,which can basically understand the connotation of mathematical modeling.A certain basic literacy.The main difficulty for students in mathematics construction is that it is difficult to translate practical problems into reasonable mathematical problems and to ignore the existence of solutions after solving them.At the same time,students feel the mathematical modeling experience in mathematics teaching.There are not many.Secondly,interviewed some teachers' views on the integration of mathematical modeling literacy into mathematics teaching.Through interview records,teachers believe that the cultivation of mathematical modeling is very necessary for the long-term development of students,and teachers also have mathematics.Modeling literacy incorporates the awareness of practical teaching but rarely implements it,lacking awareness of student application Thirdly,with the "Pythagorean Theorem" as the teaching content,by recording the teaching situation of teachers under different teaching consciousness and the learning situation of students,comparing the influence of mathematical modeling literacy and mathematics teaching on the teaching effect,it is found that there is application.The Mathematical Modeling of Consciousness Class can improve students' ability to analyze and deal with problems,but it is also a challenge for students and teachers.Above-mentioned investigation and the case analysis of the "Pythagorean Theorem",the teaching thinking of the "typed teaching process" is proposed,and the application-oriented problem with life situation is introduced as the learning new knowledge.Based on the students' pre-study ability,the teacher-student cooperation Exploring new knowledge and openly letting students report and summarize knowledge.We believe that this is conducive to improving students' mathematical modeling literacy,and gives a case design of mathematical modeling literacy in teaching.
