Unit 3 Computers 教学设计

经验告诉我们，成功是留给有准备的人。作为高中教师就要根据教学内容制定合适的教案。教案可以让学生们能够在上课时充分理解所教内容，帮助高中教师能够井然有序的进行教学。您知道高中教案应该要怎么下笔吗？为满足您的需求，小编特地编辑了“Unit 3 Computers 教学设计”，但愿对您的学习工作带来帮助。

本单元的话题是IT技术，计算机的发展史和机器人。

WarmingUp部分通过展示算盘、计算器、计算机等图片，引导学生思考计算机的不同形式，并要求学生运用“做决定”的表达。

Pre-reading提出两个问题，引导学生谈论计算机对我们生活的影响。引起学生对计算机这个话题的兴趣。

Reading部分运用拟人的手法，以第一人称的身份按时间顺序介绍了计算机的发展史。

Comprehending部分主要要求学生掌握以时间为线索的文章的特点，并能通过填写时间表来归纳出文章的主要信息。

LearningaboutLanguage部分的练习引导学生关注新出现的词汇以及形容词和副词的区别；并且通过仿照例子，初步掌握“现在完成时的被动语态”。

UsingLanguage部分的听说读写都是围绕不同形式的信息技术和不同种类的电子计算机各自的优缺点这两个话题展开训练。而且要求学生在听说读之后，能用上“做决定”、“推理”的表达法和“现在完成时的被动语态”进行报告，学会写作关于机器人话题的文章。

LearningTip部分建议学生多从图书馆、报刊、杂志、网络等途径，多方面来增加词汇、提高听说读写的能力。

将WarmingUp部分与Pre-reading,Reading,Comprehending部分放在同一课时教学，设计成一节阅读课。

将LearningaboutLanguage及Workbook（WB）中的UsingStructures放在一起教学，上一节词法、语法课。把UsingLanguage中的Readingandspeaking部分的阅读文章布置为课外阅读作业。

将UsingLanguage中的Listeningandwriting，Speakingandwriting（把ReadingandSpeaking中的任务改为“向老师销售电脑”）和Writing部分设计成一节语言运用课（1），重点是培养学生“说”的技能。

把UsingLanguage中的Writing部分布置为课外作业。将WB中的Listening、Talking和ListeningTask结合在一起，设计成一节语言运用课（2），重点是培养学生的“听”的技能。把WB中的Usingwordsandexpressions布置为课外作业。
