一、关于情境创设。案例:《认识乘法》这是二年级的数学,课本上的情境图展示了小动物兔和鸡,由此引导列出算式:2+2+2和3+3,再向乘法形式过渡。本来这个课题用图导入就可以了,但一位教师多费了点心思,开场出示了一段flash视频:“小鸡啄米,小兔跳舞,流水潺潺,绿树摇摆。”这的确是天堂世界啊!画面亮丽,引人入胜。等到视频播完,教师问学生:“怎样列式计算兔有几只、鸡有几只?”学生
First, on the creation of the situation. Case: “Knowing Multiplication” This is a second-grade math. The textbook scenario shows a small animal rabbit and chicken, which leads to lists the formulas: 2 + 2 + 2 and 3 + 3, and then transitions to multiplication. Originally the subject of the introduction of the map can be, but a teacher took a bit more thought, the opening shows a flash video: “This is indeed the chicken peck the rice, bunny dancing, gurgling water, green trees swing.” Heaven world! Beautiful picture, fascinating. Wait until the video broadcast finished, the teacher asked the students: “How to calculate the number of columns of rabbits, how many chickens?” "Students
