苗族银饰文化融入小学数学课堂的教学实践——以两位数乘两位数的教学为例

The Incorporation of Mathemataical Elements in Culture of Miao into the Mathematical Teachings in Primary School: Illustrating by Presenting“Two Digits Number by Two Digits Number”

以美丽的苗族服饰为数学教学情境,以问题为主线把苗族文化融入小学数学课堂来进行"两位数乘两位数(不进位)"的教学,课堂上教师利用苗族配饰中的银帽作为数学信息,从数一顶银帽的银角到计算12顶银帽的银角,通过"教师提出问题、引导学生解决问题"的方式进行课堂教学.在快乐的教学活动中,使学生知道苗族服饰中隐藏着许多的数学知识,让学生懂得生活中处处有数学,这样的教学根植于当地的民族文化,使学生的学习具有亲切感和民族自豪感,这有利于激起学生的数学学习兴趣.

In the presentation of ＂two digits number by two digits number＂,the teacher supplies Miao apparels as props to explain to students the mathematical elements inherited in the culture of Miao by enumerating silver pieces attached to the silver hat. The whole process is carried out in the way of ＂ask and answer＂. In this way,the teacher makes a chance for students to acknowledge the mathematics hidden in Miao apparels,and makes students be sure that the mathematics is common in everyday＇s life. The teaching in this way has its origin in local culture,so it makes students feel friendly and proud in learning maths,and on the other hand,it also improves students＇ desire of learning maths.
