高中英语必修二：Unit+3+Computers+教案4+
Unit 3 Computers一、整体设计思路本节课的教学设计是基于人教版New Senior English For China Student’sBook 2Unit 3 Computers Using language (Workbook) 的Listening and Speaking 部分。
授课内容是关于电脑和机器人话题的听说课，融合听说读写等综合运用语言的能力，重点突出听说能力。
在教学过程中，有目的有重点训练学生的语言应用能力，对多项语言技能的训练进行适当的整合，使其相互渗透促进。
听说读写四项技能中，读和听是输入，说和写是输出，将语言输入和语言输出有效地联系起来，从而更好地培养学生运用英语进行交际的能力。
二、教材内容分析本节课的话题是computers 和 robot，是与学生的日常生活息息相关的话题。
这一单元的话题是围绕电脑的发展以及机器人的相关知识开展的。
其中本单元中的语言运用（Using language）部分涵盖了听说读写等四项技能的运用，但因课堂时间较为有限，不能面面俱到，因此本节课的重点在于听和说这两方面。
听的部分是通过强调听力技巧，通过“听前”“听中”“听后”让学生提高听力效率，了解三则广告中三种不同机器人的信息。
说的部分是在一定的情境下，通过学生小组合作编对话的形式为自己的家庭选择一款适合的机器人并表明原因。
三、学生情况分析作为高一的学生，对电脑和机器人方面的知识应该已经有所了解和熟悉，也具备些相关的词汇和表达，而且这个话题也是学生所较感兴趣的话题之一。
但是，很多同学对于听说是存在畏惧感的，特别是高考对于英语综合能力的考察日益增强。
语音是否准确，语速是否流畅，是否能听懂信息进行问答，能否及时记录关键信息点进行语言输出等等这些情况都是我们老师在听说课活动中要考虑到的实际问题。
同时，还有些学生缺乏自信，不愿开口，担心出错等等，那么教师所设计的活动要求就要由浅入深，层层递进，逐步培养和提高学生运用英语进行表达的言语能力。
高中英语必修二：unit3+Computers说课稿
必修二Unit3Computers说课稿本课是高一必修模块2第3单元的阅读课，这篇题为Who am I的课文以第一人称的拟人手法介绍了计算机发展演变的历史和计算机在各个领域的广泛应用，其主旨是表达计算机的发展之快以及在生活中用途之广。
虽然计算机这个话题是我们日常生活中熟悉的话题但是本单元课文属于科普类说明文，内容抽象，专业术语多，对高一学生来说比较有难度。
教学目标结合本课教学内容，具体从语言知识、语言技能、情感态度三个方面制定如下教学目标。
1. 语言知识目标：使学生了解计算机的相关词汇，能够通过学习简单了解计算机的发展史。
2. 语言技能目标：a)阅读技能的训练：让学生学会克服生词障碍，通过略读，归纳出文章的大意b)学习怎样找主题句(topic sentence)和支持性细节(supporting details)；3.情感态度与文化意识目标：a）了解有关计算机的发展史，并通过讨论活动激发学生对计算机的兴趣。
b）培养学生的合作意识和“合作学习”的习惯。
教学重点和难点：根据《普通高中英语课程标准（实验稿）》关于读的技能目标的具体描述，结合高一学生实际和对教材内容的科学分析，确定本环节的主要教学重点和难点是: 1．重点1）让学生了解计算机发展史。
2）训练学生的阅读技巧，提高阅读能力。
学会找主题句和支持性细节信息：a.根据主题快速捕捉文章重点细节的能力。
b.总结归纳能力。
2．难点1) 如何使学生在有限时间内尽可能多的熟悉并记忆一些与计算机有关的词语。
2) 如何使学生学会在阅读理解和书面表达中辨别并使用主题句，达到语言实践能力的扩展与提高。
教学设备：多媒体设备教学方法本节课主要采用任务型语言教学法(Task-based Language Teaching) 、合作学习教学法（Cooperative Learning Approach）。
教学程序结合本校高一学生实际和对教材内容的科学分析，计划用40分钟完成本文的教学任务，具体安排如下：(一) Pre-reading：激发学习兴趣，明确学习任务。

高中英语必修二Unit3Computers阅读课的教学设计及反思
高一年级英语必修二第三单元教学设计姓名：邓丽琼班级：340、343Unit 3Computers一、教学设计思路本课设计以WHO AM I?为课堂教学材料，以学生现实生活为出发点和归宿点，旨在发展学生的语言实际运用能力。
本设计以学生中心，运用了图示理论，采用了pair work, group work, class work等活动形式，串联成环，前后环环相扣，帮助学生理解课文，用自己的英语重新诠释课文，并初步具备知识迁移能力。
二、学习任务分析本单元的中心话题是“计算机”，内容涉及计算机的发展历史、计算机的应用等，其中还谈到包括计算机在内的几种信息技术的载体、智能计算机的发明等等。
不过，整个单元多以计算机为第一人称进行自白，这种拟人的手法使得文章谈起来妙趣横生，抽象的专业知识介绍起来也浅显易懂。
本主旨语篇WHO AM I ?以计算机的口吻自述其发展演变的历史以及计算机在当今世界各个领域的运用。
表达了计算机的发展变化之快以及在生活中用途之广。
三、学习者分析计算机这一话题虽然有趣，但本单元所选语言材料属于科普类说明文，内容较为抽样，文章中也不乏一些专业术语，对于高一学生来说有一定的难度。
目前，学生上课以interpersonal交流为主，而interpretative和presentational 形式比重不够。
由于文化教学不够重视，学生的跨文化意识不高。
此外，学生跨学科学习的意识不够，语言和信息的双向促进关系的认识不够。
对于比较策略主要运用在英汉汉英互译的语言层面，未进入文化比较和思维比较。
学生的课外语言活动环境不够丰富和重视程度不够，通常以词汇、语法和写作练习为主，缺乏真实的语言运用。
四、教学目标(1) Language Skills：1. Use “decision making”expressions like “I believe... in my opinion, etc”correctly.（activity 1）2. Develop their predicting and reorganizing skills.（activity 2,3,4,6）3.
