新老教材中直线与圆锥曲线差异问题比较研究

The Comparison Research on the Differences between Straight Line and Conic in the Old and New Version Textbooks

直线与圆锥曲线在解析几何、代数、三角和平面向量中均有论述,是高考的主干知识和重点考查内容,而新老教材中涉及直线与圆锥曲线问题存在一定的差异,值得教师深入研究,文章就此问题作一些比较、分析、研究和教学建议。

Straight line and conic are discussed in analytic geometry, algebra, triangle and vector in the plane and key knowledge and test focus in National. College Entrance Examination. But there exist differences concerning straight line and conic in the old and new version textbooks which are worth study. The paper compares, analyzes, studies the differences and advances teaching suggestions.
