本节课的内容和呈现方式是在对学生实际情
( http: / / www.21cnjy.com )况进行充分调查的基础上进行设计的，所以总体效果良好，事实证明对学情的充分了解和把握对于课堂教学是极为重要的准备工作。
本节课结合学生感兴趣的小动物---
( http: / / www.21cnjy.com )-鸵鸟进行内容整合，让学生在认知鸵鸟的过程中轻松达成学习目标，做到词不离句，句不离篇。将重点内容循序渐进的渗透给学生，让学生逐步接受新授内容。
信息技术和多媒体技术对于当前小学英
( http: / / www.21cnjy.com )语教学有着极为重要的作用，能够使我们的教学内容更为丰富，呈现方式更为多样，视听结合也更能激发学生的学习兴趣。
在学生活动的设计上还有欠妥当之处，可以给学生更加丰富的活动，让更多的孩子参与其中。(共39张PPT)

教学重点是：听、说、认读单
( http: / / www.21cnjy.com )词“big,
small,
long,
short”并学会用它们描述物品。并且能够听懂、会说句型“It
is…”和“It
has…”,利用句型熟练自如地描述各种动物。
教学难点是：能够区分“It
is…”和“It
has…”
情感目标：
让学生感受到动物的可爱，教育学生要爱护动物、尊重生命。
培养学生参与教学活动的主动性，提高他们的学习积极性。
教学准备：
多媒体、课件、动物图片、单词卡。

本节课选自人教版小学英语三年级下册Uni
( http: / / www.21cnjy.com )t3
At
the
zoo中Part
B
Let’s
learn这一部分。本单元的教学内容主要是围绕学生们感兴趣的动物园里的小动物展开。主情景图主要通过学生参观动物园时交流使用的语言呈现本单元将要学习的重点知识，共分为A、B、C三部分。A部分主要呈现四个形容词“tall,
short,
fat,
thin”使学生能在动物园这个情景中灵活地当地使用词汇及句型“Look
at…
It
is…”来描述动物。
而本节课将要呈现的B部分的教学内容是继续学
( http: / / www.21cnjy.com )习四个描述性形容词“small,
big,
long,
short”，通过教学活动使学生能够熟练掌握这四个描述性的形容词，并能够用“It
has…”对动物进行具体描述。课本中将四个单词在鸵鸟身上不同部位进行了呈现，利用了学生感兴趣的小动物进行教学，符合学生的认知能力和年龄特点。因此在本节课中教师利用鸵鸟对课本内容进行了整合，形成了一篇新的文本内容，将重点单词与句型融入其中，让学生在真实的了解动物的过程中完成本节课的教学目标。
