Research On Quadratic Function Teaching Under The Mathematical Core Literacy

With the steady development of society,science and technology have developed gradually,culture becomes more influential,and mathematics has gradually shows its own value.As an important component of human civilization,mathematics not only carries culture and thoughts,but also plays an important role in natural science and social science.Therefore,our country gradually pays attention to the cultivation of students' core mathematical literacy.The promotion of mathematics core accomplishment is not only an innovation of basic education,but also puts forward higher requirement for teaching.It is the difficult point that how to teach mathematics better and how to integrate the core literacy into the teaching of mathematics based on the concept of the new curriculum standard.The knowledge of quadratic function is rich,which contains the content of mathematical core accomplishment,so the research has more practical significance.And quadratic function,as an important function knowledge in junior high school,is not only a major branch of elementary function,but also connected with the knowledge content between junior and high school.However,it's very difficult for junior school students to learn quadratic function.Because no matter from the concept,images and properties of the understanding,as well as the comprehensive application of other knowledge,quadratic function is undoubtedly the most difficult of all.In the background of the quadratic function teaching,more vivid teaching not only helps to guide the students to grasp the concept of quadratic function,images,and the nature of the relevant knowledge,also can helps students to master knowledge of quadratic function by means of mathematics thought method.At the same time,students can develop good study habits so that achieve the goal of core literacy cultivation.This paper uses research methods which includes literature research,questionnaire survey,interview and case analysis.First of all,through the research and analysis of relevant literature on quadratic function teaching,the theoretical support of the research paper was obtained,and the research status of quadratic function teaching under the core accomplishment of mathematics was understood.Then the paper analyzes the learning requirements of quadratic function in the course standard,the investigation contents ofquadratic function in the middle school examination and the connection contents of quadratic function in the middle school and high school,and obtains the important position of quadratic function in middle school mathematics.In order to further understand middle school teaching and learning situation of quadratic function in hainan area,we design the student questionnaire and teacher interview outline,quadratic function to the student's study present situation,as well as the questionnaire survey of high school mathematics teacher interview to the quadratic function of the teaching situation.Then we will analyse the results of statistics and current situation of teachers' teaching and students learning situation.For the purpose of implementing core literacy training,which is based on literature research,based on survey and the interview results,put forward the mathematical core accomplishment of the quadratic function of the teaching principles and strategies,the quadratic function unit teaching and two specific class teaching in the teaching design,teaching and evaluation and reflection.The paper focuses on reasearch of quadratic function teaching under the core literacy of mathematics.The research results not only help students develop their core literacy,but also have certain practical significance for teaching.
