小学英语Unit 3 Lesson 2 教学设计一 教学内容分析：本节课的教学内容是外研版Join in （三年级起）四年级下册第三单元第二课。本节课含有四个一般疑问句以及与动物相关的单词。猜测动物提问的方式为学生提供了学习语言和运用语言的语境，提升了学生的英语学习兴趣。二 设计理念：为了让学生能够将本单元重点一般疑问句的句型进行听、说、读、写系统操练并掌握运用，本课设计了英语情境查找犯罪嫌疑人。整个课程贯穿的主线是警察查找犯罪嫌疑人，询问目击者。本课学生作为警察，老师作为引导者，假象一只猫作为目击者，通过完成一个个任务来达到找出犯罪嫌疑人的目的。学生通过小组竞赛获得部分线索，通过讨论获得更多线索，每一个环节设计都运用了本单元重点句型Has it got,? Is it ？Does it ? Can it ? 引人入胜的情境让学生充满好奇和热情运用所学投入破案的过程，不但掌握了句型，还突破了本节难点，全班参与度也非常高。三 教学目标：1. 语言知识目标：能够理解和运用以下句型：Is it ?Has it got?Can it ?Does it ?2. 语言能力目标：学生能够形成英语思维能力，主动运用所学句型在实际中运用，达到交流的目的。3. 情感态度目标：充分理解人类和动物共同生活在一个地球上，尊重爱护动物。四 教学重难点：1. 教学重点：第三人称单数的一般疑问句的运用，动词相关搭配。2. 教学难点：（1） Does it ? 句型的动词以及助动词的运用对于学生是个难点。（2） 学生对于老师的教学设计流程和指令有可能理解不清楚。五 学生分析：本节课的授课对象是四年级学生。本班大多数学生的英语学习兴趣浓厚，上课参与度非常高。大多数学生的英语基础比较好，并且在听说方面有优势。同时，他们的特点是活泼好动、对课外事物好奇心强，更有主人翁意识，愿意参与课堂。所以课程设计要符合他们的特点，不但要能调动学生的参与积极性，还要有一定难度和挑战，发掘学生更高潜力，巧设情境，让学生有明确目标，积极参与。六 教学媒体与资源：多媒体、ppt、板书卡片、“线索”纸条七 教学过程：ProcessTeachers activitiesStudents activitiesPurposeWarm-up and reviewShow the chant “I like animals”with music.Ask the students to chant together.Chant together and review the names of animals.复习动物单词并且使学生迅速进入课堂状态，活跃气氛。Lead in1.
