什么叫“变式”?即变换事物的非本质特征,从不同角度组织感性材料,在各种表现形式中突出事物的本质特征。“变式”的类型有变题型、变条件、变问题、条件和问题互变等等,变式可以加强学生的数学技能和思维训练,在应用题教学中对数学条件和问题进行多角度,多方面的变式,可以引导学生发现“变”中“不变”的本质,同时还可以让学生探索“不变”中的“变”的规律,让学生在变式中触摸思维的脉搏,从而加强学生的创新意识,提高思维品质。下面浅谈一下在小学数学应用题教学中的
What is the “variant”? That is, the transformation of the non-essential characteristics of things, organized from different perspectives of sensual materials, prominence in various manifestations of the essential features of things. Variants can change students ’mathematical skills and train their thinking. Variants can improve students’ math skills and thinking skills, apply mathematical problems and problems in applied teaching Multi-angle and multi-faceted variations can lead students to discover the essence of “immutable” in “transmutation” and at the same time allow students to explore the law of “transmutation” in “immutable” Let students touch the pulse of thinking in the variant, so as to enhance students’ innovative awareness and improve the quality of thinking. Now let’s talk about teaching mathematics in primary school
