Research On The Cultivation Of Mathematics Core Competencies In The Teaching Of Mathematics Core Concept In Senior High School

This paper focuses on how to cultivate the core quality of mathematics in the teaching of mathematics core concepts in senior high school.In the traditional mathematics teaching,there are the following problems: 1.the transformation of teaching ideas.2.in the course of preparing lessons,how do teachers clarify the content of core concepts and determine what kind of core qualities a certain mathematical core concept can cultivate for students? 3.Through the cultivation process of core concepts,how to cultivate students' quality of integrating theory with practice and using basic mathematical concepts as a tool to solve problems.Through the analysis and research of the above problems,through literature search,this paper expounds and collates the core concepts of mathematics and mathematical core literacy,and interprets the relevant theories according to the literature,and compiles the framework of the questionnaire and the interview outline.26 teachers from Harbin No.6 Middle School and Hainan Dongpo School were questionnaires to investigate teachers' perception of core literacy in the teaching design of mathematics core concepts,and to analyze teachers' perception of teaching design and mathematics core literacy.According to the analysis results,this paper puts forward some teaching strategies for the cultivation of mathematical core literacy in high school mathematics core concept teaching,and puts forward some ideas on how to carry out teaching design.Two cases of "the concept of function" and "the judgment of parallel lines and planes" are selected for teaching design.Firstly,the reasons for choosing this lesson as a case are analyzed,as well as the teaching materials,learning conditions,teaching objectives and difficulties.In the process of teaching,mathematics knowledge is used as the carrier,problems are used as the driving force to design teaching links and analyze design intentions.Finally,the case is reflected and relevant optimization suggestions are made.The results show that: through investigation and interviews with front-line teachers,aiming at some problems in teaching,such as: some teachers' understanding of the teaching of mathematical core concepts and their complete grasp of the conceptual system are not enough;the teaching of mathematical core concepts has not attracted enough attention,and the pertinence is not strong in the course of preparing lessons and teaching;and the understanding of the connotation of mathematical core literacy is not enough.Sufficiently profound,we can not find an effective way to cultivate and improve students' mathematics core literacy in teaching;we do not attach enough importance to the application of situational teaching,pay more attention to students' ability to take exams in teaching,and pay less attention to revealing the essential attributes of concepts and other issues,and put forward corresponding countermeasures for how to implement the cultivation of students' mathematics core literacy in the teaching of mathematics core concepts.Strategies are as follows: 1.Teachers should strengthen their own professional construction and grasp the core conceptual structure as a whole;2.To strengthen the learning of the Curriculum Standards,understand and understand the connotation of the core mathematical literacy,and understand the corresponding level division;3.To formulate teaching objectives that highlight the core mathematical literacy in teaching;4.To stimulate students' learning enthusiasm by introducing rich teaching scenarios;5.In teaching,we should attach great importance to revealing the essence of concepts,and integrate mathematical culture into teaching strategies.
