在对新世纪的中学生提出的素质要求中,核心是新时期的创新精神和创造能力,培养学生的创造性思维成了当今教育的首要任务。利用数学变式是培养学生创造性思维很有效的途径之一。本文总结了数学变式的多种方法,通过逆向变式提升思维的深刻性、灵活性;通过结论引申提升思维的新颖性、独创性;通过综合变式提升思维的广阔性、流畅性。尝试数学变式的教学,可以提高学生的思维能力和数学学习的能力,点燃创造性思维的火花。
In the quality requirements put forward by the middle school students in the new century, the core is the innovative spirit and creative ability in the new era. It is now the primary task of education to train students’ creative thinking. Using mathematical variants is one of the most effective ways to cultivate students’ creative thinking. In this paper, we summarize many methods of mathematical variants, and enhance the profoundness and flexibility of thinking through the inverse variation. We extend the novelty and originality of thinking through the conclusion, and enhance the broadness and fluency of thinking through comprehensive variants. Attempting to teach mathematical variants can enhance students’ ability to think and math and ignite the spark of creative thinking.
