数学是一种理性的精神,使人类的思维得以运用到最完善的程度,这是美国数学家克莱因对数学的诠释。数学知识本身就散发着理性之美,数学教师应该努力使我们的数学课堂呈现出理性色彩。然而,在日常教学中,以下的案例并不鲜见——数学老师提问:“小明和15个同学去坐船,每条船最多5人,至少要几条船?”有孩子列好算式:16÷5=3(条)……1(人),回答的时候说的是至少要3条船。老师很生气:“怎么会
Mathematics is a rational spirit, so that human thinking can be applied to the most perfect level, which is the American mathematician Klein’s interpretation of mathematics. Mathematical knowledge itself exudes a rational beauty, mathematics teachers should strive to make our mathematics classroom showed a rational color. However, in everyday teaching, the following cases are not uncommon - a math teacher asks: ”Xiao Ming and 15 classmates going to the boat, each boat up to 5 people, at least a few boats?“ Formula: 16 ÷ 5 = 3 (Article) ...... 1 (people), when answering the said is at least three ships. Teacher is very angry: ”how can
