作为组成数学思想方法重要部分,数形结合是数与形相通性的反映,相互间能在一定条件下进行转化。高中数学实践教学中的数形结合形式主要体现在:针对形的相关属性利用精确的数来阐明;针对数与数之间的关系利用直观的几何来阐明。通俗来说数形结合就是以形助数和以数解形。为此,本文就高中数学教学中数形结合的实际应用进行了探析。 As an important part of the method of forming mathematical thinking, the combination of number and shape is the reflection of the connection between number and shape, and can be transformed under certain conditions. The combination of the forms of number and form in high school mathematics practice teaching is mainly reflected in that: the relevant properties of the shape are clarified by using precise numbers; the relationship between the numbers and the number is clarified by using the intuitive geometry. In general, the combination of number and shape is based on the number of aids and the number of solutions. For this reason, this article has probed into the practical application of the combination of number and form in high school mathematics teaching.
