日本著名数学教育家米山国藏指出:“作为知识的数学出校门不到两年可能就忘了,唯有深深铭记在头脑中的是数学的精神、数学的思想、研究方法和着眼点等,这些都随时随地发生作用,使他们终身受益。”为此,为了学生的终身可持续发展,作为数学教师要深入地了解和钻研数学思想方法,在教学中,不仅应当重视显性的数学知识的学习,而且应重视数学思想方法的渗透。 The well-known Japanese mathematics educator Mishan Guosang pointed out: “Mathematics as a knowledge can not be forgotten in less than two years, but only in the mind is the spirit of mathematics, the thought of mathematics, the research methods, and the focus of attention And so on, all of these will take effect anytime, anywhere, for their lifelong benefit. ”Therefore, for the purpose of students’ lifelong sustainable development, mathematics teachers should deepen understanding and study of mathematical thinking and methods in teaching, not only should pay attention to explicit Mathematical knowledge of learning, and should pay attention to the penetration of mathematical ideas and methods.
