六上 U7 Protect the earth 第二课时 教学反思

刚刚得知自己任务时, 我内心很忐忑, 因为没有录过没有学生的网课, 一时间不知该怎么设计更好. 幸好在黄校, 孙校, 和组内陆老师, 卞老师, 邵老师的帮助下, 顺利的录完了课. 现反思如下:

在教学过程中,教学目标起着十分重要的作用.教学活动以教学目标为导向,且始终围绕

实现教学目标而进行.

本节课是第二课时,主要内容为Grammar time 中use … to … , should 用法, Fun time中reuse … to … 和Culture time两个节日,根据以往教学经验，我认为这些内容对孩子来说比较简单, 第二课时是建立在第一课时基础上, 所以我把目标定位在了提升上.在快速复习story time后, 进行知识点教授, 随后将主要部分放在了如何运用部分. 我设计了看图说句子, 创编对话, 写创意书等活动。

在试上中, 我产生了疑惑,活动看着很丰富, 但有效吗？要知道这节课是学生单独在家听课,缺少互动,交流,他能真正的参与到这些活动中来吗? 孙校与同组老师给了我建议, 首先要明白孩子上课背景,它并不是提升课堂内容, 而是更多对课堂内容的的一种预习或者回顾.所以我们课堂的定位, 应该是以书本为主, 把该教的教扎实, 该讲的讲透.作为第二课时,更多应该是继续围绕本单元话题 “ protect the earth”, 对第一课时的巩固,复习, Grammar time, Fun time 知识点讲解,操练扎实, Culture time 背景意义了解清楚。如果说第一课时是了解protect the earth 这一概念，知道通过save这个活动来保护地球，那第二课时就是深入学习protect the earth的方法，复习how to save ,学习 use… to … 和 reuse … to …这两种保护地球的方法。所以本课应该是围绕：save and reuse，复习与学习。

目标不同，教学设计自然也不同，我对课有了新的思考，首先是回顾protect the earth这一概念，复习环节由原来的“回忆课文，判断对错”一个环节，扩充为四个环节，由课题earth, 引入与earth有关系列单词wood , water, coal，energy，对文中重点单词进行复习，随后读一读story time唤醒课文内容回忆，再进行课文内容判断，最后根据上节课大家一起总结出的思维导图进行复述，层层深入，承上启下。

回顾课文后，学生再次明白资源的可贵，那我们可以利用这些资源做什么呢？对于Grammar time中use … to…的用法，我们考虑到有的孩子课外知识不丰富，他也许不知道生活中一些物品的原材料是什么，课堂上会有别的孩子补充，可独自在家，无人可以帮助他。所以，我先进行了一个“说说这些东西原材料”的活动，为孩子接下来的运用打好基础，然后进行对各种物品发挥想象，了解他们的功效。

资源可贵，可这些资源是用之不尽的吗？我用一个小视频让孩子了解了资源的现状，从而引出how to protect the earth. 随后引入culture time了解两个保护地球的节日， 以及我们在这个节日和平时生活中该如何， 最终引发 should save , should reuse and recycle, shouldn’t waste这几个中心话题.由于 reuse … to… 的用法是建立在use … to …上，不需要过多教授，所以又在运用上适当增加了一些内容，培养孩子语言综合运用能力。

最后通过作业“find more ways to protect the earth”,引发孩子更多思考，为下节课 make a poster做好准备。

令人遗憾的是，reuse与recycle有所区别，但在短短二十分钟内，似乎很难讲明白，最后放弃了进一步辨析，在接下来还会继续思考，希望能够解决这个遗憾。
