5 突出数学思想方法的理解与简单应用重视数学思想方法的教学与考查是一种共识,问题在于怎样落实和落实哪些基本数学思想方法?近年来的中考题主要采用了情景题、探索题、开放题、应用题等方式来考查学生的思维能力与创新意识,有的地方还通过操作实验的过程来认识数学的本质。中考题所体现的基本数学思想方法主要有:用字母表示数的思想、集合与对应的思想、函数与方程的思想、转换化归的思想、数形结合的思想、建立数学模型的思想、抽样统计的思想等;数学解题方法主要有:消元法、降次法、代入法、因式分
5 highlighting the understanding and simple application of mathematical thinking method Emphasis on teaching and examination of mathematical thinking is a consensus, the problem lies in how to implement and implement the basic mathematical ideas and methods? In recent years, the test questions mainly use the scenario, explore questions, open Questions, application questions and other ways to examine the thinking ability of students and innovative awareness, and in some places by operating the experimental process to understand the nature of mathematics. The basic mathematical thinking methods embodied in the examination questions are as follows: using the methods of alphabetical representation, collection and correspondence, thought of function and equation, conversion of naturalization, combination of ideas and mathematics model, sampling Statistical thinking, etc .; mathematics problem solving methods are: Elimination method, reduction method, substitution method, due to factor
