这堂课,张仁守老师讲“圆柱体侧面积”。他让学生在各自准备好的圆罐头筒上剪下围着的商标纸,然后引导他们从长方形、正方形、平行四边形的面积计算推导出圆柱体侧面积的计算公式。学生动手操作,动口讨论,动脑思索,教师象谈心般地点拨,整个教学过程轻松和谐。一个学生课后说,在家里,爸爸、妈妈总把我看成不懂事的孩子,让我做饭时,连放多少水也要为我准备好。来到学校就不一样了,一个公式的推导,求一道复杂应用题的解,张老师总相信我们通过自己的努力能做到。有的问题我一时弄不懂,查查书本,或和同学们讨论一番,大体上能弄清楚,再经老师一指
This lesson, Zhang Shuren teacher said “cylinder side area.” He asked the students to cut the encircled logo paper around their prepared cans and then led them to derive the formula for calculating the area of the side of the cylinder from the area of a rectangle, a square, and a parallelogram. Students hands-on operation, talking about the mouth, brains, teachers like to talk like dial, the entire teaching process easy and harmonious. A student said after class, at home, my father and mother always think of me as a naive child, let me cook, even put how much water should be prepared for me. Came to school is not the same, a formula derived, seeking a solution to complex application problems, Zhang always believe that we can do through their own efforts. Some problems I sometimes do not understand, check the book, or to discuss with students about, in general, to figure out,
