Teaching Research Based On Cultivating Mathematics Abstraction Core Literacy

In recent years,the term "core literacy" has increasingly become the focus of attention and discussion in educational policies,teaching practices and other aspects in educational circles around the world.Among them,the core accomplishment of mathematical abstraction occupies the most important and basic position among the six core accomplishment of mathematics discipline,and it is closely related to other core accomplishment,which is interrelated with each other.In high school,the abstract core accomplishment of mathematics determines whether the students can accurately grasp the mathematical characteristics of the research object,whether they can use the relevance of mathematical knowledge to establish a complete knowledge network,and whether the abstract core accomplishment of mathematics can be effectively cultivated and developed in this critical period.Function is the content of the core module of high school mathematics.Although it is difficult to find the special chapter of abstract function in the catalogue of teaching materials,the concept and properties of function are closely related to it,which are all given in the form of abstract function.Therefore,this paper takes the abstract core accomplishment of mathematics as the theoretical basis,takes the abstract function of high school as the carrier,centering on how to train students' abstract core accomplishment of mathematics in high school mathematics teaching to carry out research.Firstly,this paper adopts the literature research method to sort out and integrate various literatures related to the core accomplishment of mathematical abstraction and the study of abstract functions at home and abroad,and sort out and analyze the abstract function knowledge in the curriculum standard textbooks and the college entrance examination.Then the questionnaire survey and interview were designed for the students and teachers of the practice school to understand the status quo of abstract function teaching of high school students based on the abstract core accomplishment of mathematics,and according to the survey results,the teaching strategies for cultivating the abstract core accomplishment of mathematics of high school students were provided.Finally,based on the proposed teaching strategies,two teaching cases are designed with reference to the excellent teaching design and the advice of the practice instructors.This paper is different from the previous study of mathematics abstract core literacy,is no longer limited to the levels of measurement to the student,is no longer limited to the specific function through a complete analytic expression of learning for analysis,but rather on abstract functions the wiring,as the carrier,the investigation analysis about the present situation of students' learning,and based on the investigation to the conclusion that students choose way,introduced more easy to accept new knowledge,make full use of teaching AIDS,will be full of knowledge generation process further breaks down,lack of knowledge structure formed in the process of the teaching material of administrative levels sense,write out the more accord with students' learning and cognitive ability of teaching design,for a line of teachers The teaching of abstract function can provide reference and reference.
