数学变式教学通过各种变式,揭示概念原理的实质,促使学生更好地掌握其精髓,进而培养了学生的思维品质,并通过变式多方位、多角度地引导学生探索,提高数学应变能力,促进思维的灵活性和创新性,利用变式构造反例,揭示事物本质,培养学生的思维批判性。因此,在初中数学教学中有效运用变式教学,对于提高数学教学的有效性有着十分重要的意义。
Through a variety of variants, mathematical variant teaching reveals the essence of the concept of principle, prompting students to better grasp its essence, and then cultivate the students’ thinking qualities, and through a variety of ways to guide students to explore and improve mathematics strain Ability, to promote the flexibility and innovation of thinking, the use of variants to construct counterexamples to reveal the nature of things, to develop students’ critical thinking. Therefore, the effective use of variant teaching in junior high school mathematics teaching is of great significance to improve the effectiveness of mathematics teaching.
