人教版高中英语必修二Unit 3 Computers第四课时Writing 教学设计庆阳第六中学 曹红霞I、学情分析本节课的教学对象为高一(3)班学生,大多数学生英语词汇量小，基本的英语表达能力弱，阅读和写作能力较低，这节课是本单元的第四课时-写作课。这节写作课是运用本单元前三课时所学的重点词汇、短语和句型进行与单元话题-计算机相关的写作教学。基于这样的学情，在教学中我特别强调首先让学生听懂课堂指令，有时会辅助汉语提示，逐渐地引导学生获取信息，提炼信息，运用信息，然后用学生自己所学所积累的英语知识进行写作，在此过程中形成自己的学习技能和策略，学会把语言和现实生活联系起来。通过任务型课堂活动和学习，让学生自主参与课堂活动，并以小组形式和其他成员合作学习。、教材分析 这是本单元的第四课时。在这之前学生已经学过了本单元的新词汇和两篇阅读课文。本节课教材上的内容是Using Language部分的写作练习。因此基于这个单元的话题进行与学生生活息息相关的话题写作教学。本课时主要帮助学生积累与计算机相关的常用词汇，短语和句型，同时注重训练和培养学生的写作能力，。 、Teaching aimsKnowledge aims:By the end of the lesson,students will be able to1.master how to write a composition2. remember some key expressions and sentence patterns3. finish a compositionMethods and strategies:1.Develop studentswriting skills such as how to list the strucutre of a composition2.Encourage students to use what they have learned to write a compositionEmotional aims:1.Encourage students to cooperate with other students2.Stimulate studentsinterest in computers and learning about some funtions of computers.IV、 Teaching important points:1.Develop studentswriting skills such as how to list the strucutre of a compositionV、 Teaching difficult points:1.Enabe students to master how to write a compositionVI、 Teaching methods：Task-based teaching method, individual work, group discussionVII、 Teaching aids：Multimedia facility, a textbookVIII、Teaching procedures：Step 1.
