Research On Teaching Strategy Of Function Concept In Senior Middle School Based On Mathematics Core Literacy

Mathematical core literacy is the necessary thinking quality and key ability to adapt to the development of oneself and society,It embodies the goal of mathematics curriculum in senior high school and its formation and development are through the study and application of mathematics,so The core accomplishment of mathematics must permeate into every link of mathematics teaching.Mathematics core literacy is the basic accomplishment to promote the all-round development of human being,and it is the basic accomplishment that every citizen should possess.In senior high school,function runs through the course of mathematics teaching in senior high school,so it is very important to study the concept of function.Under the background of the new curriculum standard of mathematics in senior high school,the author makes an investigation and analysis of the concept of function in high school students based on the mathematical core literacy.Through literature research,interviews and test questionnaires,the author selects senior high school teachers and students from a city school in Leshan City,and first interviews them to find problems.Then according to the four aspects and levels of mathematical abstract literacy and logical reasoning literacy,the test questionnaire is designed and investigated,and the results of the survey are statistically analyzed so as to draw a conclusion.Through interviews with students and teachers,it is found that there are some problems in the function comprehension of students:(1)it is difficult to understand the abstract concept of function because of lack of interest in its learning;(2)they are not understand the concept of function well and not in-depth understanding of the nature of the function;(3)students cannot evaluate their abilities accurately.Results of interviews with teachers:(1)the most prominent mathematical core literacy in the concept of function is the mathematical abstract literacy;(2)cultivating mathematical core literacy,different teachers have different ideas,some teachers think that the situation should be introduced,and some teachers should pay attention to the design of teaching activities.Through the research data,it is found that the cultivation of mathematical abstract literacy in senior high school students is better than logical reasoning literacy in the course of functional concept learning.On the whole,students have obvious differences in four aspects: situation and problem,knowledge and skill,thinking and expression,communication and reflection.The situation and problem are the best,knowledge and skills are the second,communication and reflection is the third.Worst thinking and expression.At the same time,it is found that the level of students in different literacy is also different.Investigation and Analysis on the cultivation of Mathematical Core Literacy in the concept of function of Senior High School students,Put forward relevant teaching strategies:(1)to create a life-oriented functional situation to inspire students to think about it;(2)put forward effective function problems to promote students mathematical thinking and expression;(3)organize cooperative exchange activities to improve students knowledge and skills;(4)attach importance to the integration of curriculum and information technology to improve the teaching effectiveness;(5)perfecting teaching evaluation system and focusing on mathematics core accomplishment.
