Study On The Variable Type Teaching Of Ellipse

Conic section is an important content of high school mathematics, it fully reflects the analysis thinking. Elliptic, hyperbolic, parabolic is conic curve of three parts. The first part of the teaching and learning of ellipse, will directly affect the back of hyperbola and parabola of learning, but also the entrance of conic most often appear in the title. The new curriculum reform emphasizes the importance of the teaching of the ellipse, but there still exist many problems in the teaching of the ellipse, seriously affected the subsequent teaching conic curve, so it is very important to improve the teaching of the ellipse. In the process of teaching peactice and reading literature, I found that the teaching of the ellipse have many content related with variable type. From actual contions, This paper sorts through change of elliptic type teaching,analysis,summary, explore one of the common problems, and find general law.Firstly, research background of elliptic to carry on the analysis, find the direction of research, and combined with literature to determine the research questions. Then the variant theory summarized, analyzed, summarized the theoretical foundation of the thesis. Then this paper analysis and put forward the variable type teaching and its application in the case of ellipse. Then we choose some teaching cases in teaching experiment shows that local variable ellipse theory can effectively improve the status of teaching based on the ellipse, and find its problems and shortcomings, finally this paper gives the suggestions aiming at the existing problems.This paper mainly adopts the literature method, interview method:, case analysis, the main conclusions are as follows:(1) On the basis of previous research, analysis and summary of changing teaching concepts and theoretical basis of(2) By combining the teaching practice of high school teaching, then gives the basic form and principle in the implementation of elliptic teaching the.(3) For the change of teaching to explore the analysis of ellipse, ellipse and found teaching theory can be effectively combined, promote teaching.(4) For the change of teaching to explore the analysis of ellipse, summarizes the elliptical variant teaching results.(5) the case of elliptic teaching analysis, the change of several problems need to be paid attention to in the teaching of the ellipse.
