解析几何是高中数学的重点和难点.有相当一部分同学解答解析几何总是“毫无头绪”甚是苦恼.究其原因,主要是学生没有掌握解析几何的思维特征和基本思想,对于题目中的几何关系、代数关系不能够准确转化,找不到条件与条件之间的联系.针对这种情况,本人在教学实践中,着意培养学生的转化意识,对提高学生解答解析几何的能力,收到了良好的效果.下面从三个方面谈谈自己的做法.1分析几何条件的本质特征转化成合理的代
Analysis of geometry is the focus of high school mathematics and difficult.A considerable number of students to answer the analytical geometry is always “no idea” is very distressed. The reason is mainly because students do not grasp the analytical geometry of the thinking characteristics and basic ideas for the title In the relationship between the geometry, the algebraic relationship can not be accurately transformed, can not find the connection between conditions and conditions.In response to this situation, in my teaching practice, I intend to cultivate students ’awareness of transformation, to improve students’ ability to resolve the geometry, Received good results. Here are three ways to talk about their own practice.1 Analysis of the essential characteristics of geometric conditions into a reasonable generation
