连续执教了几年六年级,自认为对教材、课堂基本上已经做到了了然于心,能轻松驾驭。有一次我们六年级数学老师集体备课探讨“圆的面积”如何教时,我回想起以往的教学经验,径直说:“这节课的内容如果放手让学生去探究面积的话,时间就不够用了。我以前就是让学生说说自己的想法,然后老师在前面用教具或课件演示把圆转化成长方形的过程的,这样得出圆的面积公式了,才有时间巩固练习。”我的经验之
Continuous teaching a few years sixth grade, since that textbooks, the classroom has basically done a heart, can easily manage. Once we had a sixth-grade math classmate in class to discuss how “round-area” taught me, I came back to my past teaching experience and went straight to say: "If the content of this lesson is to let students explore the area, then time Not enough.I used to let students talk about their own ideas, and then the teacher in front of the teaching aids or courseware to demonstrate the circle into a rectangular process, so come to a round area formula, only time to consolidate the practice.
