  • 部编版小学语文二年级下册第9课《枫树上的喜鹊》优秀教案范文

    部编版小学语文二年级下册第9课《枫树上的喜鹊》优秀教案范文

    教材分析:《枫树上的喜鹊》是一篇童话故事,这篇课文叙述的线条简洁、明快,情节简单、干净,语调较为活泼,符合儿童的心理特点和阅读接受能力。但是这篇童话又与众不同的地方在于,一般的童话大都采用第三人称叙述,讲述者是置身事外的。而这篇童话采用的是第三人称和第一人称穿插叙述的方式,把一个带着童真、童趣的眼睛去看待周围事物的孩童展现在我们的面前。这个童话故事告诉我们:童话就在我们身边,人人都可以创造童话。  学情分析:二年级的学生,已经对童话故事有浓厚的兴趣,好奇心强,但缺乏一定的鉴别能力。大多数学生活泼、好动、大胆且独立,他们已经掌握了识字的方法,喜欢读书,但语言的表达能力、逻辑思维能力欠佳,有意注意的时间还比较短。
