众所周知,分析问题情境是把握命题方向,构建解题思路行之有效的方法之一。在日常教学中,教师应把剖析问题情境作为突破理解题意,转化解题思路的突破点,这样不仅能够帮助学生提高解题思维能力,更能拓展其探索、发现数学思想方法的空间,达到提高教学效果的目的~([1])。1创设“新定义”型信息题的情境问题分析“新信息背景问题”是指用“课外知识”的叙述形式展示“课本内容”的一类命题方法,其主要目的是告 As we all know, analyzing the situation of the problem is one of the effective ways to grasp the direction of the proposition and to build a solution to the problem. In daily teaching, teachers should analyze the situation of the problem as a breakthrough point to understand and solve the problem, so as to not only help students improve their problem-solving thinking ability, but also expand their space for exploration and discovery of mathematical thinking and methods to achieve Improve the teaching effect of the purpose ~ ([1]). 1 create “new definition ” type information problem analysis of the situation “new information background problem ” refers to “extracurricular knowledge ” narrative display “textbook content ” a class of proposition method, the main The purpose is to tell
