The Teaching Designs Of "Mathematical Modeling Activity" In Middle School Based On The Mathematical Core Literacy

Mathematics plays a decisive role in the development of science and technology.Mathematics pushes the progress of society.Mathematical modeling as a bridge between real society and mathematical knowledge is essential in mathematics education.Quality education is the core of today's education.The formation of subject literacy is the goal of teachers' teaching.Mathematical modeling is the cultivation of students' comprehensive ability,so that students not only learn mathematics knowledge,but also explore the further application of mathematical knowledge,so it can be seen that mathematical modeling plays an important role in mathematics teaching.Mathematical modeling is the cultivation of students' comprehensive ability,so that students not only learn the knowledge of mathematics,but also develop their vision to see the further application of mathematical knowledge.Mathematical modeling plays a vital role in the development of students' personal life,the quality of thinking and the cultivation of critical abilities to meet the needs of the society.For mathematical modeling,teaching methods,forms and methods are still in the exploratory stage in middle school.Students should also take into account the pressure of middle school learning,and acquire better theoretical knowledge and practical ability.The teaching of mathematical modeling is based on the cultivation of students' core mathematics literacy,therefore,the author investigated the current situation and influencing factors of mathematical modeling activities in middle schools,and put forward strategies for developing mathematical modeling activities in secondary schools.Mathematical modeling is a required section in "the standard of mathematics curriculum for ordinary high school(2017 Edition)"(hereinafter referred to as "the new standard").This shows the importance of mathematical modeling and the cultivation of the students' ability to apply mathematics.Based on the cultivation of the ability of mathematical application,the core quality of mathematical literacy is gradually formed.Mathematics and mathematics are complementary.Mathematics application is the inevitable trend of social development.However,our students have a good grasp of basic knowledge of mathematics,but they are weak in mathematics application,mathematics knowledge,practice and innovation.Based on the requirements of mathematics curriculum standard,the development of school and teacher's mathematical modeling activities,and the actual learning situation of students,combined with the cognition and research carried out by mathematical modeling in secondary schools,I put forward:The core literacy of mathematics is that schools and teachers should not only focus on teaching materials,but also cultivate people who need social needs.The teaching of mathematical modeling pays attention to the learning process of the students,and transforms the mathematical knowledge into mathematical and mathematical literacy.The difference between the second,mathematical modeling teaching and traditional teaching:(1)mathematical modeling teaching content and teaching material is open and wide,do not have to follow the example of other plates required follow book knowledge,teachers consciously choose to live closer to the teaching material;(2)the innovation of teaching form modeling mathematics activity class,regular classroom teaching is difficult to fully take into account the process of exploration,the students practical ability and application ability,thus can carry out mathematics practice suggestions;(3)innovative teaching methods course of mathematical modeling activities,the teaching process should be equal dialogue between teachers and students,build harmonious teacher-student relationship and interactive teaching;(4)mathematical modeling activity changes the dynamic role of teachers and students,teachers have advanced education ideas,good learning,good at cooperation,while students from passive learning into active acquisition,by the listener into thinkers,they are learning partners.
