国际数学大师陈省身先生有言:“数学简单,数学使一切科学变得简单。”数学学科本身就是倡导简约的,公式定理的简明、解题思路的简洁、符号书写的简单、语言叙述的简练、计算方法的简便,等等。数学课堂教学不能脱离数学的本质特征,有效数学教学需要简约,以人为本、因材施教离不开简约,简约应该成为实效课堂的追求。 Mr. Chen Sanshi, an international math teacher, said: “Mathematics is simple and mathematics makes all science easy.” The mathematics itself is advocating simplicity, conciseness of formula theorems, simple solution to problems, simple writing of symbols, and language narration Concise, simple calculation method, and so on. Mathematics classroom teaching can not be separated from the essential characteristics of mathematics, effective mathematics teaching needs simple, people-oriented, can not do without teaching students according to their aptitude, simplicity should become the pursuit of effective classroom.
