数学试题与求解是一对矛盾的两个方面.在一定条件下,矛盾的双方可以互相转化.解答数学试题就是创设条件,促成转化,转化思想主要是由未知向已知,由复杂向简单,由条件向结论,由陌生向熟悉的单向转化.对称化思想的理解程度极大地制约解题能力的发展.因此要使学生掌握、理解把复杂问题转化为简单问题的基本思想方法,在中考数学试题上考查学生对转化思想的理解程度和灵活运用转化方法的试题几乎达到无处不在的程度,但从转化的目的来看,可以分为四种类型,本文分别进行举例分析.
Under certain conditions, the contradictory parties can transform each other.Mathematical questions is to create conditions to facilitate the conversion, the conversion of ideas mainly from unknown to known, from complex to simple, From the condition to the conclusion, the unfamiliar to the familiar one-way transformation.The degree of understanding of the symmetrical thinking greatly restricts the development of the ability to solve problems.Therefore, to enable students to master and understand the basic ideas and methods of converting complex problems into simple problems in the test On the math test exam students’ understanding of transformational thinking and the questions of flexible use of translation methods almost reach the ubiquitous level. However, from the perspective of transformation, they can be divided into four types, which are respectively analyzed by examples.
