构造法是指根据题设条件或结论所具有的特征和性质,构造出一种新的熟知的数学模型,从而使问题化难为易,化繁为简,达到准确、快速解题的目的.因此,在初中数学解题中,教师要引导学生灵活地运用构造法,培养学生思维的灵活性,提高学生的解题能力.一、构造方程法
Constructive method is to construct a new familiar mathematic model according to the character and nature of the conditions or conclusion of the inscription, so as to make it easy to solve the problem and simplify the problem so as to achieve accurate and quick solution to the problem. , In junior high school mathematics problem solving, teachers should guide students to flexibly use the construction method to cultivate the flexibility of student thinking and improve students’ ability to solve problems.
