高中生的思维具有很强的发散性、开放性和可塑性,在教学中若能利用学生的这一思维特点,引导学生灵活应用转化思想进行解题,不仅有利于激发学生学习数学的兴趣,而且有利于培养和提高学生观察、分析、联想、类比的能力。圆锥曲线是高考重点考查内容,学生理解起来颇感抽象,活用转化思想以巧解圆锥曲线是值得我们一线数学教师不断探讨一种的方法。1.抽象与具体的转化将一些抽象的圆锥曲线问题具体化,或具体到某个定义、某种几何性质、某种图
High school students ’thinking has very strong divergence, openness and plasticity. If students can take advantage of this thinking characteristic in teaching to guide students to flexibly apply conversion thinking to solve problems, it not only helps to stimulate students’ interest in learning mathematics, but also Help to develop and improve students’ ability of observation, analysis, association and analogy. Conic curve is the key content of the entrance exam, students understand quite abstract, the use of transformation thinking to cleverly conic curve is worth our first-line mathematics teachers continue to explore a way. 1. Abstraction and Concrete Transformation Concrete abstraction of some conic curve problems, or to a certain definition, some kind of geometric nature, some kind of figure
