Research On Cultivating Students' Mathematical Abstract Literacy In Mathematical Function Teaching In Senior High School

The general high school mathematics curriculum standard(2017 edition,2020 Revision)puts forward the core literacy of high school mathematics.In high school mathematics teaching,it is the unshirkable responsibility of mathematics curriculum to implement the cultivation of students' mathematics core literacy.There are six core qualities of mathematics,among which the abstract quality of mathematics ranks first,which is closely related to the characteristics of mathematics.Mathematical abstract literacy can help people understand the objective world from the perspective of quantity and form.It is an indispensable basic literacy for people to live in contemporary society.The study of mathematical abstract literacy is the need of the times of mathematics education.It is very necessary to study the implementation of mathematical abstract literacy in mathematics teaching.Mathematics knowledge in junior middle school and primary school is concrete,abstract and easy to understand.After entering senior high school,mathematics knowledge is more abstract and complex.Especially in the learning process of function,students' thinking will also change from intuitive thinking to abstract thinking.This transformation process is very key.Many students have problems in the learning process of function,which makes their grades decline seriously.This has led to a sharp decline in interest in learning mathematics and a gradual loss of self-confidence.Therefore,in high school mathematics teaching,taking the function part as the main representative,it is of great significance to cultivate students' mathematical abstract literacy.After reading the relevant literature,this paper focuses on the research related to mathematical abstract literacy and function teaching,arranges and analyzes it,understands the previous research on mathematical abstract literacy and function teaching in senior high school,and lays a foundation for the writing of the paper;Questionnaire and test paper survey were carried out.The subjects of the survey were the first grade students of Practice school.The main purpose was to understand the students' attitude and method of learning mathematics,the learning of the concept and nature of function and the level of mathematical abstract literacy;Through the communication with the teachers of senior one mathematics group,we learned their understanding of mathematical abstract literacy,their implementation in classroom teaching,and in their opinion,the level of students' mathematical abstract literacy,which provided a practical basis for the writing of the paper.After analyzing the results of the survey,the author finds out the problems and puts forward five teaching strategies according to the problems: create a familiar problem situation for students to stimulate their interest;Put forward effective mathematical problems to inspire students' thinking;Give full play to the role of information technology and effectively combine curriculum teaching with information technology;Improve the classroom teaching evaluation system and evaluate students from multiple angles;Change the classroom teaching mode and advocate 6+1 efficient classroom teaching.Through the implementation of strategies,to cultivate and improve students' mathematical abstract literacy,so that students can better learn follow-up knowledge.According to the proposed teaching strategy,the experimental method is adopted to design and implement the teaching,so as to test the effectiveness of the proposed strategy,test the feasibility of the proposed strategy,and summarize the experimental conclusions.In the end,the research work is summarized and deficiencies are found.In the near future,the proposed strategy should continue to be optimized and the research work will continue.
