所谓构造法,就是运用各种知识和方法,依据问题的条件和结论给出的信息,把问题做适当的加工处理,构造与问题相关的数学模式,揭示问题的本质,从而得到解题思路的方法.因此,用构造法解数学问题时,需要对所提问题的结构特点有深刻的认识,然后通过敏锐的观察、适当的变形、广泛的联想将难以解决的数学问题,转化成简易的基础题、平时比较容易解决的问题或几何图形,使得问题形象直观,难点得到分解、转化,从而解决问题,它是一种重要而灵活的解题方法.
The so-called structural method is to use various knowledge and methods, according to the conditions and conclusions of the information given, the problem to do the appropriate processing, construction and mathematical problems associated with the model to reveal the nature of the problem, so as to solve the problem of thinking Method.Therefore, when solving the mathematics problem by means of constructivism, we need to have a profound understanding of the structural characteristics of the questions raised, and then transform the difficult to solve mathematical problems into a simple foundation by keen observation, appropriate deformation, extensive association Question, usually easier to solve the problem or geometry, making the visual image of the problem, difficult to be resolved, transformed, so as to solve the problem, it is an important and flexible solution to the problem.
