【摘要】“认识0”是苏教版一年级第五单元的学习内容,是在学生认识了1~5之后教学的。本课要让学生在具体的情境中认识0,知道0的含义并学会读写。“0”这个数字对小学生来说并不陌生,虽然刚上一年级,但是丰富的生活经验使学生都知道“0”表示一个也没有,只是他们对0的认识还不够系统、全面,对于“0”的其他含义并不清楚,于是笔者在教学中注重对“0”的全面了解,并注意激发兴趣,让学生乐学,联系生活使学生爱学。

Make Learning Fun, Make Students Fall in Love with Learning and Learn Happily
——"Knowledge 0" Teaching Case and Reflection
(Wanhong Primary School, Zhangjiagang City, Jiangsu Province,China) XIANG Juan
【Abstract】"Knowledge 0" is the learning content of the fifth unit of the first grade of the Jiangsu Education Edition, which is taught after students have met 1-5. In this lesson, students should recognize 0 in specific situations, know the meaning of 0, and learn to read and write. The number "0" is not unfamiliar to elementary school students. Although they are just in the first grade, they have a wealth of life experience, so that students know that "0" means none, but their understanding of 0 is still lacking in a systematic and comprehensive way. I am not clear about the other meanings of "0", so in teaching, I pay atten‐tion to a comprehensive understanding of "0", and pay attention to stimulating interest to make students enjoy learning, and connecting with life to make students love learning.

【案例一】
教师:前面我们已经认识了1、2、3、4、5,今天我们要认识一个新的数。老师先给大家讲个故事:森林里一连下了好几天的雨,终于迎来了阳光明媚的星期天。这一天正好是兔妈妈生日,小兔们一早就出去采蘑菇想送给妈妈作生日礼物。我们一起来数一数,兔妈妈一共有几只兔宝宝呀?(集体点数,集体回答。)
教师:大家继续看,他们分别采了多少个蘑菇?(出示幻灯片1)老大采了3个蘑菇可以用数字几来表示?老二采了2个蘑菇可以用数字几来表示?老三采了1个蘑菇可以用数字几来表示?老四一个蘑菇也没有采到,那用几来表示呢?
学生:用“0”表示。
教师:对,一个蘑菇也没有采到就用“0”表示。0和1、2……一样,也是一个数。这节课我们就来学习“0的认识”。(板书课题)
【评析】苏霍姆林斯基认为,教学的起点,首先要激发学生的学习兴趣和愿望。美国著名教育家夸美纽斯在《大教学论》中生动地将学习比喻成吃饭,吃饭要有食欲才能吸收,学习要有兴趣才能接受。
