。。As the core content of analytic geometry in senior high school,the conic section plays a very important role in the cultivation of students’mathematical thinking ability。To understand the different concepts of the conic section,to know the consistency of unity and centrifugal rate,and to master mathematical thinking ideas,teachers need to have an overall understanding and an essential cognition of the historical context and knowledge formation process about the conic curve。Based on the analysis of the historical development of conic section,teaching goals,textbook compilation,and students’actual situation,this paper tries to reconstruct the concepts of conic section teaching,in the hope of addressing the key problems in teaching。
