三年级的学生学习了有余数的除法后,经常会遇到这样的测试题:三年级(2)班有45人去公园划船,每条船坐8人,需要多少条船?学生列式45÷8=5(条)…5(人),答对正确答案“6条”的不到五分之三。题目难吗?不难!可就是有部分学生会出现错误。问题出在哪里?是在数学课堂中,太多机械练习造成的结果。老师们只不过充当了数学知识“贩卖者”的角色,把数学知识从书本上,以自己个人的理解,以自以为是的方法传授给了学生,却忽略了数学的实质。“
The third grade students learn the division of the remainder, often encounter such test questions: third grade (2) class 45 people go to the park rowing, each boat sitting 8 people, how many ships? ÷ 8 = 5 (bar) ... 5 (people), less than three-fifths of the correct answers ”6“. The problem is difficult? Not difficult! But there are some students will be wrong. Where is the problem? It is the result of too much mechanical practice in math class. Teachers merely act as maths ”trafficker “ role, teaching mathematics from the book to their own personal understanding, self-righteous way to pass on to the students, but neglected the essence of mathematics. ”
