Unit 4 Seasons Lesson 3 Little Leaf 教学设计

四上 Unit4 Seasons Lesson3 Little Leaf 教学设计
一、教材分析：
本文与鲁科版英语教材四年级上册第四单元 Seasons 相匹配，本单元的四个语篇从不同角度谈论季节，单元内各语篇与单元主题之间，以及各语篇之间相互关联，构成四个子主题，即“认识四季”“感受四季”“热爱四季”“感悟四季”。
本节绘本故事是在课文的基础上的扩展和延伸，主要讲述了小树叶在四季的经历:在春日中伸展，在春风中舞蹈，在春雨中淋浴，在夏日中成长并为人类奉献树荫，在秋日着霜并变换颜色，在冬日离开大树，化作春泥滋养大树，来年大树长出新的树叶，生命在四季变换
中轮回。学生通过阅读绘本故事，了解如何描述小树叶在四季的经历，感受生命在四季轮回中成长并充满希望，激发学生享受四季生活、尊重生命、热爱自然、保护自然的情感。同时引导学生感悟随着季节的推移，小树叶和好朋友们的心情变化，体会小树叶的伟大，进而迸发出热爱自然，保护自然生态的美好情感。
该绘本为配图故事，通过精美的插图和简洁明快的文字相结合，按照季节顺序呈现为四个部分，采用一般现在时，对小树叶在四个季节的活动进行了描述，语言简洁、生动、富有韵律感，凸显出绘本的主题意义。
二、学情分析：
四年级学生年龄在十岁左右，生性活泼好动，喜欢直观形象，爱唱、爱跳、爱玩、善于模仿，敢于开口。通过两个学期的学习，他们已经掌握了一些常用的问候语和对话，有了一定的词汇量，能听懂简单的课堂用语，能根据老师的指挥做出适当的回应。但是，他们的注意力时间仍然比较短。所以设计课堂活动的时候要有一定的思考性、趣味性，能带给他们一定的新鲜感，才能吸引他们的兴趣，才能使每个学生参与到课堂学习活动中。因此，在教学设计时，我面向全体学生，以学生的发展为宗旨，始终把激发学生的学习兴趣放在首位。同时，多给他们说的机会，提高他们的口语水平，提升他们的语用能力。
三、教学目标：
通过本课时的学习，学生能够:
1.在看、听、读、演的活动中，了解故事的发展，提取故事的核
心信息，总结故事的主要内容，获取、梳理小树叶四季的变化，感知
和理解故事内容。(学习理解)
2.在图片、板书和语言支架的帮助下，复述故事主要情节，感受
小树叶的伟大。(应用实践)
3.通过读图、观看视频等方式，在教师的帮助下总结保护地球自
然生态的举措，结合生活实际，完成给地球的回信并报告。(迁移创
新)
四、教学重难点：
引导学生深入理解《Little Leaf》绘本的内容，体会小叶子从生长到凋落的生命历程，以及它所传递的关于成长、变化和生命意义的深刻寓意，树立热爱自然、保护自然生态的意识。
