Research On Functional Learning Status Of Senior High School Students From The Perspective Of Core Literacy

The 2017 edition of The General High School Mathematics Curriculum Standard proposes six core qualities of mathematics:mathematical abstraction,logical reasoning,mathematical modeling,intuitive imagination,mathematical operation and data analysis.Topic two function is the cornerstone of the general high school mathematics curriculum.How the students develop the core literacy of mathematics in the stage of function learning and how the effect of function teaching are directly related to the students' mathematics learning in the whole stage of high school.Therefore,from the perspective of core literacy,this paper studies the current situation of students' functional learning in senior one.Firstly,literature research is used to understand the connotation,development and evaluation of mathematical core literacy,and to sort out the research results of function concept,function status and teaching,so as to provide theoretical support for the construction of the evaluation system of core literacy and the research of related contents in this paper.Secondly,using the test investigation and questionnaire survey,to understand the current situation of senior students function and mathematics core literacy cultivation,the results show that there are lots of problems for students in learning one function,the students' mathematics core accomplishment overall form is also a more general,in particular,the students' intuitive imagination literacy cultivation conditions are relatively good,The cultivation of mathematical abstract literacy is general,but the cultivation of mathematical operation and mathematical modeling literacy is relatively poor.Thirdly,test survey and teacher interview are used to analyze the factors affecting students' functional learning.The results of the survey show that the main factors that affect the students' functional learning are not skillful in basic operation and not deep understanding of concepts,not flexible in the transformation of variables and the application of function properties,only formal in the application of numerical-form combination method,and the understanding of mathematical relations in the actual problem situation.The interview results show that teachers have a clear understanding of core literacy and students' functional learning difficulties,and also provide some specific measures to help students overcome functional learning difficulties.Finally,based on the conclusion of the investigation and the factors affecting students'function learning,the following suggestions are put forward:attaching importance to the basic methods of operation and constructing the context of function knowledge;Change the teaching method and concretize the abstract problem;Pay attention to the combination of numbers and figures,strengthen the students' ability to figure out numbers;Reasonable creation of problem situation,deepen the understanding of the function.
