Unit 11 Trees

第三节

Saving Trees 本节课与上一课时相关性分析: 本节课是Unit11Trees 的第三课时，主题定为Save trees。课本的其余内容在前两个课时都已经教授完毕，剩下Learn the sounds和Culture corner这两个部分。因此教师在整合复习前两个课时内容的同时，用短文、思维导图、话题等进行拓展。除了复习第一课时树的作用和第二课时树的特征与现状外，第三课时对人类砍树的用途、应该采取什么措施拯救树木等方面进行拓展。并引导学生整合三个课时的内容进行逻辑清晰的写作，让学生对本单元所学的内容有整体的思考。

课堂拓展阅读内容：

Forests A forest has a large amount of trees. Forests are very important because they provide shelter and food for birds, animals and insects. Birds make their nests in trees. Small animals and insects build their homes in the hollows of trees. Leaves, flowers and fruit are their food. People get wood from forests. Some people cook food with wood. People cut down trees to make houses, furniture and paper. Many animals in the forest die because they lose their homes and their food. We must stop cutting down forests.

教学后记：

通过学生在课堂上的反应与参与教学活动的自主性程度，现场书写文章以及个人作业的反馈，本节课的教学效果还是比较理想的。具体阐述如下：

1.教学设计逻辑清晰，层层铺垫。本课从语音学习入手引出主题，从复习前两个课时的内容进入拓展，从各个环节的自主思考和小组讨论到最后生成逻辑结构清晰的篇章，学生在教师问题的引导下以及短文、图片、视频等资源的帮助下不断思考，最后对本单元所学的内容进行自主整合。从学生书写的文章看，学生的学习效果较好。

2.教学活动丰富，有趣且有效。课堂用了短文、图片、视频、韵律诗、思维导图等引导学生思考和小组合作学习，让课堂的每个活动都充满乐趣。比如，制作保护树木的标语，用绳子挂在教室并用于学校的环境保护标语，情境真实并触发学生完成的动力。

3.教师注重每个部分教学的逻辑关系，并帮助学生整理整个单元的学习内容，进而有逻辑地进行表达，将所学的知识外化。
