数学教学的实践表明,学生能否善于运用转化思想,教师能否指导学生运用好转化的技巧,是衡量数学教育教学质量的关键性因素之一。一、现实引发的思索崔永元在他的《不过如此》一书中写道:“对我来说,数学是疮疤,数学是泪痕,数学是老寒腿,数学是类风湿,数学是股骨头坏死,数学是心肌缺血,数学是中风……当数学是灾难时,它什么都是,就不是数学。”像崔永元这样的名人始终难以摆脱数学的恐怖阴影,其原因大多出在数学思想
The practice of mathematics teaching shows that whether students can be good at using transformation thinking and whether teachers can instruct students to apply transformation skills is one of the key factors to measure the quality of mathematics education. First, the reality triggered thinking Cui Yongyuan wrote in his “But So,” wrote: “For me, mathematics is scars, math is tears, math is the old cold leg, math is rheumatoid, math is the femoral head Necrotic, math is myocardial ischemia, math is stroke ... When math is a disaster, it’s nothing, it’s not math. ”Celebrities such as Cui Yong-yuan have been struggling with the horror of mathematics for the most part in mathematical thinking
