变换事物的非本质特征,从不同的角度组织感性材料,在不同的表现形式中突出事物本质特征的过程叫做变式。许多代数和几何的概念都是从实际生产和生活中衍生而来的,为促进学生对概念的理解,在引入概念时可以运用变式引入其本质属性。本文重点讨论了变式教学在初中数学教学中的运用。
Transforming the non-essential features of things, organizing the perceptual material from different perspectives, and highlighting the essential features of things in different manifestations is called the variation. Many algebraic and geometric concepts are derived from the actual production and life, in order to promote students’ understanding of the concept, the introduction of the concept can use variants to introduce its essential attributes. This article focuses on the use of variant teaching in junior high school mathematics teaching.
