The Concept Of High School Function Based On Mathematical Abstraction Literacy Teaching Research

In recent years,mathematics core literacy has been a hot issue around the reform of mathematics education,and the research on mathematics core literacy is also increasing.According to the basic concept of "General Senior High School Mathematics Curriculum Standards(2017 Edition)",we can see the important position of mathematics core literacy in "Senior High School Mathematics curriculum is based on students' development,carrying out the fundamental task of cultivating moral character,fostering scientific spirit and innovative consciousness,and improving the core literacy of mathematics subject".Based on the above background,this paper intends to study the implementation of mathematics core literacy in the classroom.According to the research on the core literacy of mathematics,it is found that the abstract literacy of mathematics is an important part of its six major literacy,and it is also one of the basic ideas of mathematics.As Professor Shi Ningzhong said,the essence of mathematics is to study Abstract things.From this,we can see the important position of abstract word in mathematics.Therefore,this paper chooses the abstract literacy of mathematics as one of the basic ideas of mathematics.Research object.But the research needs carriers.According to the author's combing of literature and mastery of senior high school curriculum,the representative course "Concept of Function" in the cultivation of abstract literacy is chosen as the research carrier to systematically study the implementation of mathematical abstract literacy in the classroom.In order to carry out the research smoothly,this paper adopts the methods of literature,questionnaire,test paper and interview,and establishes an evaluation framework for the four dimensions of mathematics core literacy: situation and problems,knowledge and skills,thinking and expression,communication and reflection,and the corresponding three levels of the four dimensions in mathematics Abstract literacy.247 questionnaires and test papers were distributed to analyze the dimensions and levels of students' abstract mathematics literacy in the course of "Concept of Functions".It was found that the development of students' abstract mathematics literacy was not balanced,the level was not high,and the training of teachers was not in place.At the same time,in the form of interviews,teachers' suggestions on the cultivation of abstract mathematics literacy and the teaching of functional concepts are understood.Through the investigation and interview results,the author puts forward four strategies to cultivate students' abstract mathematics literacy in the course of "Concept of Function" : creating teaching situation,perfecting Abstract process,constructing knowledge framework,developing learning system,carrying out mathematical activities,displaying thinking levels,improving learning habits and communicating and summarizing independently.The above strategies are applied to the teaching design,and the teaching design of "Concept of Function(Lesson 1)" aiming at cultivating students' abstract mathematic literacy is carried out in combination with the concept teaching theory.At the same time,by putting forward the strategy of cultivating mathematical abstract literacy,we can give one example and solve the problems of other literacy in practical teaching with similar methods.
