变式教学是在教学中用不同形式的直观材料或事物说明事物的本质属性,或变换同类事物的非本质特征以突出事物的本质特征.通过变式教学能让学生对概念、定理、公式有多角度的理解;同时通过对问题的多层次的变式构造,可以使学生对问题解决过程及问题本身的结构有一个清晰的认识,也能有效地帮助学生积累问题解决的经验和提高解决其他问题的能力.因此变式教
Variant teaching is to use the different forms of visual materials or things in teaching to illustrate the essential properties of things or to transform the non-essential features of similar things to highlight the essential features of things.Changing through the teaching of variables allows students to have concepts, theorems and formulas Multi-angle understanding; at the same time through the multi-level variant of the problem structure, students can make the problem solving process and the problem itself has a clear understanding of the structure, but also can effectively help students accumulate experience in problem solving and improve other solutions Problem-solving skills
