在数学教学中若注重对课本习题进行变式训练,不但可以抓好双基,而且还可以使学生举一反三,提高学生对数学知识的应用能力,从而培养学生的创新、探究能力.下面是圆锥曲线一道习题的变式教学的一点探讨.题目(人教版《高中数学第二册(上)》习题6)过抛物线焦点F的条直线与它交于两? In mathematics teaching, if you pay attention to the variant training of textbook exercises, you can not only do a good job of double-basic, but also can make students infer one by the other, improve students’ ability to apply mathematics knowledge, thereby cultivating students’ ability to innovate and explore. The following is the conic curve. A discussion of the variant teaching of a problem. Topic (PEP version 2 of the High School Mathematics (I)) Exercise 6) The parabola with the parabolic focus F intersects with it?
