函数、不等式是高中数学的重、难点之一,是培养学生抽象性、条理性思维的重要手段。本文与数学基础知识的夯实,数学解题方法、思路的培养和多角度审视问题及问题的一题多解进行了研究和探讨,建构二者知识间的联系,从而提高学生的分析问题和解决问题的能力。 Function, inequality is one of the difficulties and difficulties of high school mathematics. It is an important means to train students’ abstract and rational thinking. This paper studies and explores the compaction of mathematical basic knowledge, the method of mathematical problem solving, the cultivation of train of thought, the multi-angle examination problems and the multi-angle solutions of questions, and builds the connection between the two knowledge so as to improve students’ analytical problems and solutions The problem’s ability.
