《椭圆及其标准方程》说课教案(国外英文资料) Teaching design of ellipse and its standard equation Diaobingshan second high school Zhou Na Topic for lectures: ellipse and its standard equation (multimedia lecture) I. Analysis of teaching materials Study on the relationship between the curve and the equation in the front of the class, introduces the basic idea of coordinate method and analytic geometry, and the basic problem of analytic geometry, known condition curve for curve equation; through the study of the properties of curve equation. In this section, by studying the standard equation of the ellipse, the students are given a general method of deriving the general law and simplification of this class of trajectory equations. The ellipse is taken as an example to explain how to use the equation in the analytic geometry to study the geometry, the symmetry, the vertex and the centrifugal rate of the curves. For the future teaching, students can learn to use these methods when learning hyperbolic and parabola, so that they can exercise and improve the basic methods of grasping analytic geometry. Two. Analysis of students The students through the learning of conic equation, a preliminary understanding of the basic idea of the demand curve and the basic steps, but the calculation ability of students, especially the two radical simplification, bring some difficulties to the students is the standard equation of ellipse. Three, teaching design thought Second is the equation of ellipse and its standard conic linear and circular learning related knowledge after learning, so this section of teaching can be checked on the front of the knowledge, and further study for the future and other two kinds of conic curve to lay a good foundation, important to learn the content of the lesson with the nexus. We adopt independent exploration method in teaching, teaching method of discovery teaching method, the specific measures are as follows: (1) through their own practice to draw an ellipse, by the student
