随着教育教学要求的提升,目前,思维的灵活性在高中数学解题方面越来越体现其价值.解题过程中,不仅需要学生能够具有非常扎实的基础知识及其运用能力,还对学生能敏锐观察问题特征并通过分析找到解决问题的办法这方面能力提出了要求.在学生具体解题过程中,换元法是学习高中数学中非常有效的一种解题思维方式.一、换元法的概念换元法是在对数学题目进行求解的过程中将题干中的一部分看成一个整体,进而在对整体规律进行把握的基础上寻找
With the improvement of education and teaching requirements, at present, the flexibility of thinking in the high school mathematics problem solving more and more reflect its value.In solving the problem, not only need students to have a very solid basic knowledge and ability to use, but also to students Can keenly observe the characteristics of the problem and find the solution to the problem by analyzing the ability to put forward this requirement.In the process of students’ specific problem-solving, the change-yuan method is a very effective way of thinking in solving high school mathematics. The concept of law method for yuan is in the process of solving mathematical problems will be part of the problem as a whole, and then grasp the overall law on the basis of the search
