北师版小学数学二年级“认识图形”中的“认识角”一课中,有关“角的大小与什么有关”这一知识点,对二年级的小学生来说很抽象,如何让学生理解掌握它的内涵,对教师是个挑战,最近听了一节“认识角”的研讨课,发现一个值得思考的现象。下面是这节课的一个教学片断:教师出示活动角。师:请拿出事先准备好的活动的角,玩一玩。在玩的过程中,看看你能发现什么?学生活动,老师指导。
In the second grade of the second division primary school mathematics “understanding figure” in the “cognition angle ” class, the “angle of the size of what is related to” this point of knowledge, is very abstract for sophomores How to make students understand and master its connotation is a challenge to teachers. Recently, I listened to a seminar on Cognitive Angle and found a phenomenon worth considering. Here’s a lesson from this lesson: The teacher shows the corner of the activity. Teacher: Please take out the corner of the activity prepared beforehand and play. In the process of playing, see what you can find? Student activities, teacher guidance.
