变式就是在教学中变换直观材料或事例呈现的形式,使教学对象的非本质属性得到变异,本质属性保持恒在,这样就把事物的本质和非本质属性区别开来,
The variant is to transform the form of intuitive materials or examples presented in teaching so that the non-essential attributes of teaching objects are mutated and the essential attributes are kept constant. This distinguishes the nature and non-essential attributes of things.
