通过对题目条件、结论的结构特征进行观察、对照、分析,恰当地构造出新的数学模型来达到解题的目的,这种方法称之为构造法.它往往以构思新颖、方法便捷而备受青睐,同时也是训练学生创造性思维能力的有效途径.本文将对如何构造二次函数解题的策略作探讨,供大家参考. Through the observation, comparison and analysis of the structural features of the topic conditions and conclusions, a new mathematical model is properly constructed to achieve the goal of solving the problem. This method is called the construction method. It is often prepared with novel ideas and convenient methods. Being favored, it is also an effective way to train students’ creative thinking ability. This article will discuss how to construct the strategy of solving quadric function, for your reference.
