Research On Visualized Teaching Of High School Mathematics Based On Core Quality

With the rapid development of science and technology,the new era has new requirements for what kind of talents to train."2017 General High School Mathematics Curriculum Standards" advocates the cultivation of students' core literacy in mathematics teaching.Under the new curriculum standards of talent requirements,teachers should constantly strive to change the traditional teaching methods to optimize the classroom,so that students acquire knowledge in the learning process and improve the disciplinary literacy.In this context,this thesis carries out the research of high school mathematics visualization teaching based on core literacy,which aims to optimize high school mathematics teaching by using visualization,and then promote the continuous development of students' core literacy.This thesis reviews the research status of mathematical core literacy and mathematical visualization teaching at home and abroad,defines the related concepts of mathematical visualization teaching,and selects mathematical multiple representation theory,constructivist learning theory,information processing theory and brain science theory as the theoretical support of this thesis.Through the questionnaire survey,we can understand the current situation of visualization application in high school mathematics teaching,and get the practical research basis of this study.On the basis of the above,this thesis discusses the characteristics of different visual teaching tools and the relationship between them and mathematics core literacy.In order to give full play to the advantages of visualization teaching and avoid its shortcomings,this thesis puts forward three principles of high school mathematics visualization teaching,and discusses the visualization teaching of different teaching contents and different teaching links,and then preliminarily establishes a high school mathematics visualization teaching model with the core of mathematics cultivation.This thesis selects "statistical review class" as a case to introduce the specific application process of the model,so as to provide reference for front-line teachers.The author carried out teaching practice and comparative experimental research in a high school in a city to verify the effectiveness of this study.Through the analysis of the experimental results of the experimental class and the control class,combined with the teaching implementation,the following conclusions are drawn: from the perspective of the cultivation of mathematical core literacy,the selection of visual tools,the design of visual links,and the way of visual teaching can effectively cultivate students' mathematical core literacy.Therefore,based on the core literacy of high school mathematics visualization teaching has a certain applicable value,in the future mathematics teaching is worth promoting.
