1、 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 Students Book 2 Unit 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
2、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
3、，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。四、 教学目标Teaching aims:1. Help the students learn some info
4、rmation of robot.2. Practise students listening and speaking skills.3. Enable the students to listen in an efficient way and encourage students to express themselves bravely by speaking.4. Cultivate the students cooperation skill.5. Let the students talk about their preference五、 教学重难点Teaching import
5、ant and difficult points:1. Let students listen to seek information and speak to exchange information and express their ideas.2. Ask students to discuss in groups and cooperate with group members to make dialogues and make presentations for the class.六、教学过程Teaching procedures：Step 1 Lead-in1. Watch
6、a piece of video and answer the two questions.1) What is the video clip about? Answer: robot2) What do you think of robot?Possible answers: Robot is very useful and it can help people to do a lot of work. Robot can make our life interesting and colorful, etc.2. Look at the following pictures to know
7、 the functions of robot. Robots can work as fire-fighters, waiters, dancers, singers and so on. Robots can work for advance, for rescue, for war, for doorkeeping, for cleaning, etc.3. Define “robot” with one sentence. What is a robot? Robot is a machine that can move and do some of the work of a per
8、son, and is usually controlled by a computer.设计意图：开头部分从视频导入，引起学生的兴趣并引出了话题“robot”，鼓励学生谈谈对机器人的看法，同时通过一系列的图片更深入地了解机器人的种类和作用，最终对机器人下定义。该环节层层递进，逐步开展，由浅至深，充分调动了学生学习的积极性。Step 2 Pre-listening1. Predict the listening material. Before you listen to the tape, look at the following pictures and guess the conten
9、t. Possible answer: The listening material is about the different kinds of robots and what the robots can do. 2. Try to summarize the listening skills and follow the teachers advice. Advice: Listening skills1) Read the questions quickly before listening.2) While listening, pay attention to the key w
10、ords. Avoid word-by-word listening.3) Do not worry about the new words and ignore unimportant information.4) If necessary, take down the notes in brief.设计意图：该部分为过渡部分，引起listening的话题。首先通过图片进一步引导学生了解不同种类的机器人，同时猜测听力部分的内容，通过预测，为下一步的“听”做好内容方面的准备。另外，通过问题的方式来启发学生总结英语学习中的听力技巧，最后老师进行补充和总结，并给出一些合理恰当的听力技巧方面的建议。
11、Step 3 While-listening1. (Task 1) Listen to the whole text and answer the following questions.1) What is the listening material mainly about？2) What are they? A personal A personal An 2. (Task 2) Listen to the tape again. Identify the three robots in the pictures below and number them. 3. (Task 3) L
12、isten for the specific information. Listen for the third time and fill in the chart.Robot 1Robot 2Robot 3HeightAppearanceAbilityPrice设计意图：指导学生在听的过程中集中注意力，并进行记录和运用听力技巧完成听力任务。学生听第一遍时完成第一个任务，通过问题回答和填空的方式掌握整个听力的主旨大意和关键内容；听第二遍时，学生完成第二个任务，对听力材料中提及的三种类型的机器人在图片上进行筛选并排序；听第三遍时，学生在听的过程中抓住细节信息，并对三种机器人的具体信息进行填空，
13、从而更深层次地理解三种机器人的外貌，作用和价格等。该部分循序渐进，任务层层递进，通过任务和语言运用来提高学生综合运用语言的能力。Step 4 After listeningRead the listening material and make preparations for the speaking part.Part1: Ladies and gentleman, why not buy a personal robot that can do all the work around the house? It is only 35cm high and fits easily into
14、 a small cupboard. It has five arms to hold all tools and is very easy to use. It works on its own until all the jobs are finished. You type your orders into the computer keyboard and the robot will do the rest, only 5,000 yuan for the latest model.Part 2: Here is a personal pet that does not need f
15、eeding or cleaning. This bird-like robot sings beautifully and is only 10 cm high. It can jump around the cage just like a real bird. You can choose any color you like and any repair in the first year will be free. Only 500 yuan, why not choose one today?Part 3: I am a large, hard-working android. I
16、 feel lonely and would like to meet another robot for friendship after work. I am 2m tall. I like playing my guitar and singing, however, my family say I am too noisy. So if you would like a kind-hearted android to sing karaoke with. I am your mate. Please call me on my program at ROB-1234.设计意图：此环节是
17、一个承上启下的部分，一方面是对“Listening”听力部分的复习，另一方面是为“Speaking”的部分做准备和铺垫。鼓励所有学生读听力材料的内容，也训练了学生“读”的能力。Step 5 SpeakingTask 4: Discussion (In groups)Your family is thinking of buying a robot. You can afford one of these three robots that are mentioned in the listening text. Please discuss in groups and make a dialo
18、gue with your partner to decide which robot to buy and give reasons.Use these reasoning expressions in your discussion.The advantage/disadvantage is. As/Since., I think.I think /I dont think that. I agree/ dont agree.because.Give me your reasons. First., Second.What makes you think so? I decided tha
19、t.I think . because (of). I believe that.Lets decide. Lets make a decision.S/D: Son/Daughter F/M: Father/Mother设计意图：前面听力部分属于语言的输入，而这一部分说是语言的输出前所提供的语言支持。因为很多时候创设语言的交际情景让学生进行对话或表演，学生常常觉得无话可说或不知从何说起，因此在活动前教师提供相关的语言支持显得尤为重要，这样也有助于培养学生的自信，激发学生合作探究学习的兴趣，同时也加强了学生表达“偏好”时的一些重要句式结构运用的能力。Step 6 Summary & Homew
20、orkCreate your own robot in groups and design the text of an advertisement for the robot to persuade more people to buy one. 设计意图:Summary 是对一节课必不可少的总结，让学生对这节课的内容有个整体的了解和巩固。Homework 的设计是根据对speaking 的活动的一个书面的输出和延展，使学生对这节课内容再次回顾和梳理，以巩固所学的各项知识技能目标。【板书设计】Unit 3 ComputersWorkbook (Listening & Speaking)1 robot useful do a lot of work interesting and colorful machine computersII Listening 1. a personal robot three ads 2. a personal pet 3. an androidIII Speaking reasons
