变式教学就是指教师有目的、有计划地对命题进行合理的转化更换命题中的非本质特征;变换问题中的条件或结论;转换问题的内容和形式;保留好对象中的本质因素,从而使学生掌握数学对象的本质属性。通过创设变式问题情境,让学生积极参与概念的形成过程,从多角度发现概念的本质属性;通过一题多解,一题多变,多解归一,引导学生提出不同的解题方法,多层次、多角度,全方位的认识研究问题,培养学生的创新意识和创新能力。
Variant teaching refers to the teachers’ purposeful and systematic conversion of propositions to non-essential features of propositions, transformation of conditions or conclusions in questions, transformation of the content and form of questions, preservation of the essential elements of objects Enable students to grasp the essential properties of mathematical objects. Through the creation of a variant problem context, students can actively participate in the process of forming a concept and discover the essential attributes of a concept from multiple perspectives. Through a solution of multiple solutions, multiple changes and multiple solutions, students are guided to come up with different solutions, Multi-level, multi-angle, all-round understanding of research issues, develop students’ innovative awareness and innovative ability.
