构造启迪思维,构造开启智慧,构造筑就人生。所谓构造法,就是根据原有题设条件和结论的特殊性构想组成的一种新的数学形式,进而能够利用数学中的各个理论基础、公式,进行构造出满足题型所需的条件或者结论的一种数学模型。构造法是一种富有创造性的数学思维方法,它的解题关键就是把未知转化为已知,其实质体现在解法为“打破常规、另辟蹊径”。构造法在初等数学领域中的应用范围越来越广,典型的构造法构造辅助函数、方程、数列、向量、直线斜率与几何图形等方法深受师生青睐。
Construct inspiring thinking, construct open wisdom, construct and build life. The so-called construction method is based on the original problem conditions and conclusions of the special idea of the composition of a new mathematical form, and then be able to use the mathematical basis of various theories and formulas to construct the required conditions or conclusions to meet the questions A mathematical model. Construction method is a kind of creative mathematical thinking method, and its key to solve the problem is to transform the unknown into known. The essence is that the solution is “breaking the routine and finding a new way”. The construction method has become more and more widely used in the field of elementary mathematics. The typical construction method favors teachers and students in constructing auxiliary functions, equations, series, vectors, slope and geometric figures.
