An Empirical Study On Conic Curve Teaching Based On The Cultivation Of Mathematics Core Literacy In Senior High School Students

With the progress and development of society,the proposal and implementation of curriculum reform and the cultivation of successors for the all-round development of the new era are the needs and necessity of education.Mathematics is a smiling subject with knowledge,technology and practicability.The cultivation and promotion of mathematics core accomplishment is of indispensable significance to promote the all-round development of students.The combination of mathematics knowledge and daily life is the basic requirement for high school mathematics teachers.As a part of high school mathematics teaching and one of the examination points of college entrance examination,the content of conic curve plays an extremely important role in the whole high school stage of study and the development of real life.This part reflects the core accomplishment of mathematics more comprehensively,especially the students' logical thinking ability and mathematical operation ability.Mastering the content of conic curve is of great significance to the study of high school knowledge and the cultivation of mathematics core accomplishment.This study mainly uses the literature method to make a brief review of the interpretation of curriculum standards and the development and research of mathematics core literacy in China,and to understand theteaching of conic curve and the cultivation of core literacy.Then,from training goals,teaching Starting from three aspects of content and teaching design,this paper makes a conic teaching analysis based on the cultivation of the core accomplishment of high school students' mathematics subject,and theoretically analyzes what and how to cultivate it.In view of this situation,the author makes an analysis of the causes,and then changes the cognition of conic curve from the concept of teachers;(2)pays attention to the introduction and explanation of conic curve,and lays the foundation of reasoning;(3)deduces the standard equation of conic curve and is familiar with the derivation process;(4)develops imagination ability by using geometric drawing board dynamic display;(5)draws the general figure of conic curve and cultivates the consciousness of combining numbers and shapes;(6)plane vector and conic The combination of curves,geometric algebra;(7)" one problem multi-solution " and " one problem changeable ",training operation ability;(8)summing up the question type of conic curve in college entrance examination,breaking through the difficulty of operation.On the basis of this,the teaching design and analysis of a class example are shown,and Better train students.
