把苗侗建筑文化引入小学数学课堂的教学尝试——“三角形的特性”教学与反思

Teaching Design and Reflection of“Triangle Characteristic”

以美丽的苗族、侗族建筑为数学教学情境,把苗族、侗族文化融入小学数学课堂来进行"三角形的特性"教学,课堂上教师利用苗族、侗族的建筑物让学生从苗侗建筑图中寻找三角形,使学生体会到生活中处处都有几何图形,三角形就是其中的一类.通过"学生独立探索、合作交流、实践操作相结合"的学习方法进行课堂教学,使学生体验到数学和生活的丰富联系,并感受到苗侗人民的智慧,从而激起学生学习数学的浓厚兴趣.

With beautiful Miao and Dong building for mathematics teaching situation,teachers put Miao and Dong culture into the primary school mathematics classroom for ＂triangle characteristic＂teaching.In the classroom,teachers guide students to find a triangle from the Miao and Dong architecture diagram,so that students understand the geometry such as a triangle existing everywhere in life. By the＂approach of independent exploration, cooperation, communication, and practical operation ＂,students are enable to experience connection of mathematics and life,and feel the wisdom of the Miao and Dong people,which is conducive to stimulate their interest in mathematics learning.
