PEP 人教版英语 四年级下册Unit 4 At the farm B Lets learn 教学设计汕头市丰华学校 陈丹蓉教学分析：PEP小学英语教材，以话题为纲，以交际功能为主线，兼顾语言结构，逐步引导学生运用英语完成有实际目的的语言任务。本单元学习的主题是参观农场：通过孩子们参观农场来学习生活中常见的蔬菜和动物名词，并在实际语境中熟练的运用句型“What are these/those? They are.”“Are these/those.? Yes,they are. / No, they arent.”“Wow! Theyre so.”本课时学生学习的核心单词是：cows, sheep, hens, horses，拓展词：goat。教材通过Mr MacDonald给Sarah介绍农场动物的情景呈现了单词的词形和意义。学情分析：本课的教学对象是已经学过一年多英语的四年级学生，他们已经掌握了一些简单的日常用语，已学过常见动物和食物的名词，他们对英语有着浓厚的兴趣，有较强的模仿能力和求知欲。在教学中，我努力为学生创设生动、活泼、和谐、快乐的英语学习氛围，让学生积极主动地参与课堂，敢于展示自己，成为学习的主人。设计思路：1. 有关歌曲激趣导入农场情景。2. 设置4项任务，学生在完成每一项任务过程中学习一个动物新单词的单数形式。学生通过完成任务获取农场入门票。入门票分别由4幅动物图组成，每完成一项任务门票会出现一幅动物图。3. 学生带着门票进入农场。利用猜模糊图，与MacDonald以问答形式参观农场。4. MacDonald的农田被破坏了。学生通过观察动物脚印及听动物叫声，帮忙找出破坏者。在此过程中学习动物新词的复数形式，运用PPT图片进行单复数形式的对比并学习描述动物的句型。5. 找出所有动物后，运用名词复数形式结合句型，驱赶动物们回家。通过跟读，听MacDonald介绍农场。6. 分组讨论，帮MacDonald介绍农场。由几位学生代表介绍。7. 看图齐读范文。8. 作业、总结。9. 情感态度与价值观教育、评价。教学目标：1.能听、说、认读单词：horse, cow, hen, sheep, goat及其复数形式。2.能够理解句型These are. Theyre so cute/.! 能在语境中正确运用、在实际情景中交流。3.能运用句型Are these.?Yes, they are./ No, they arent. They are.讨论农场。4.情感态度与价值观：培养学生爱护动物、尊重生命的情感。教学重点：能够听、说、认读有关农场动物的单词：cows, sheep, hens, horses, goat。教学难点：1.sheep单复数的变化及horses的读音。2.运用所学语言介绍农场。教具准备：多媒体课件、大小单词卡片教学方法：多媒体辅助法、情景教学法、自然拼读法、对比法、听说法、观察法。教学过程：Step 1.
