奥苏伯尔说:“影响学习的最重要的原因是学生已经知道了什么。”一堂数学课,如何才能把握好教学的起点和突破口呢?教学《圆的面积》一课时,学生发言热烈,大胆探究,共同推导出圆的面积公式,然而在课后却出现了部分学生用圆的周长公式来计算圆的面积的现象。我通过多次尝试,得到了一些启示。下面让我来追寻一下学生学习的 Ausubel said: “The most important reason for learning is what the students already know. ” A math class, how to grasp the starting point and breakthrough in teaching? Teaching “round area” class, students speak However, after the class, some students used the circle circumference formula to calculate the circle area. I got some inspiration through many attempts. Let me search for students to learn
