Teaching design of ellipse and its standard equation (first hours) Liu Dongfeng, second high school, Songyuan 138000, Jilin I. Analysis of teaching content This class is the new high school curriculum standard textbook of people education press A mathematics elective section second 2-1 second chapter 2.2.1 ellipse and its standard equation of the first class Conic section is an important geometric model There are many geometric properties These properties are widely used in daily life, production and science and technology meanwhile Conic curve is also an important material to embody the thought of combination of figures and figures The method of deriving the standard equation of ellipse has a direct analogy to the deduction of hyperbolic and parabolic equations It provides the basic model and theoretical basis for learning hyperbolic and parabolic contents Therefore, this lesson has the function of connecting the past and the future This is the focus of this chapter Two, students learning situation analysis In the previous study, students have experienced the coordinate method to study the equations of straight lines and circles Familiar with the basic steps of finding curve equations But the simplification ability contains two radical equation in the modeling of weak Jane But the coaching teachers can complete smoothly And because ellipses are widely used in real life The basic model will be very interested to explore the ellipse Be able to take an active part in research Three, design ideas 1, the new curriculum standard emphasizes that mathematics teaching is not only the teaching of basic knowledge and basic skills At the same time, we should pay attention to the historical background of knowledge and its application in real life In the three links teaching strategy namely creation of context - guided inquiry and abstract modeling - Application and reflect
