Research On The Current Situation Of Life-oriented Mathematics Teaching Of High School With Core Literacy

"Life-oriented teaching" is an important concept proposed from the perspective of the development of science,technology and economy,as well as the cultivation of students' learning and practical ability.As required in Mathematics Curriculum Standards for General High Schools(2017 Edition),good situation creation and problem design are conducive to the development of core qualities of mathematics in teaching activities.Mathematics teaching is not simply to "feed" knowledge to children,but to enable students to perceive and experience the application value of knowledge in real life on the basis of mastering knowledge through teaching activities.On the basis of predecessors,this paper further analyzes and summarizes the concept definition of "lifelike mathematics",and makes it clear that "lifelike mathematics" should include "lifelike mathematics" and "math-like mathematics".The former is the teaching means while the latter is the teaching purpose,and the two complement each other.Then,from the perspective of promoting the development of the core quality of mathematics in senior high school students,this paper makes a practical investigation and research on the current situation of teachers' implementation of mathematics life-oriented teaching and combined with the conclusion and problems obtained,put forward some suggestions on mathematics life-oriented teaching.The research content of this paper can be divided into the following aspects:Part one: Introduction of relevant educational thoughts and functions.Tao xingzhi's educational thought of "unity of knowing and doing",Dewey's educational view and realistic mathematics educational view have laid a theoretical foundation for the implementation of life-oriented teaching.Secondly,the paper expounds the functions of life-oriented teaching of mathematics,which mainly includes four aspects: stimulating learning interest,serving as a ladder to understand mathematical knowledge,and ways to cultivate mathematical modeling ability and carriers for accumulating activity experience.The second part: The explanation of the teaching material source.Mathematics exists everywhere in life.The materials of life-oriented teaching can be derived from students' life and experience,social life and experience,objective things and phenomena,historical allusions and scientific discoveries and development.Then the contents of the living material in the new textbooks are statistically explained.The third part: Current situation investigation and conclusion summary.Through the design and implementation of questionnaires,test papers and interviews,data collation and analysis,this paper presents the implementation status and existing problems of life-oriented teaching of high school mathematics,summarizes the conclusion,and points out the challenges faced by teachers in life-oriented teaching.The fourth part: Proposals for Implementation.According to the problems existing in the life-oriented teaching,this paper puts forward some reflective Suggestions,including accurately grasping the life-oriented teaching concept,changing the teaching view and mathematical view,and creatively using teaching materials,etc.,in order to better promote the development of students' core mathematical literacy,which undoubtedly puts forward higher requirements for the teaching literacy.This paper not only has the theory analysis,but also lists the effective cases of high school mathematics life-oriented teaching to promote the combination of teaching theory and practice.
