Unit 3 Computers 教学设计
Unit 3 Computer 教学案Part One: Teaching Design (第一部分：教学设计)Period 1: A sample lesson plan for reading(WHO AM I？)AimsTo talk about computerTo read about computerProceduresI. Warming upWarming up by talking about computerLook at the pictures on page 17. What are they？What do they have in common？Yes，they are computers. Then what is a computer？A computer is a machine which stores knowledge in its memory and does calculations on that knowledge. This knowledge is stored in symbols；it is called data. A computer usually has a monitor to show results. However，some computers can speak；these computers can be used for voice mail.计算机室A computer frequently requires a boot device. The boot device contains the computer’s operating system and data. Computer programs can be installed onto a computer. Some people think that computers are less useful if they do not have access to the Internet. They think this because the Internet allows the computers to send and receive data and email across the world.曙光3000巨型计算机A computer is now almost always an electronic device. It usually contains materials which are toxic；these materials will become toxic waste when disposed of. When a new computer is purchased in some places，laws require that the cost of its waste management must also be paid for. This is called product stewardship.In some countries old computers are recycled (melted down) to get gold and other metals. This is dangerous，because this procedure releases the toxic waste into the water and soil.Computers become obsolete quickly. Very often they are given away and new ones replace them within two or three years. This makes the problem worse. Computer recycling is thus common. Many projects try to send working computers to developing nations so they can be re-used and will not become waste as quickly.Computer jargon 计算机行话Computer jargon means words to do with computers and surrounding topics. Knowing what these words mean can help you know more about computers. Some people use these words to impress other people (Also known as buzzwords).Examples of jargon:Bit - The smallest data unit，can either be a “0.” or a “1.”.Byte - unit of data. See also Kilobyte，Megabyte，Gigabyte and NibbleCPU –Central Processing Unit，Another name for processorData - Information stored on a computerDisk - A place to store data.Email - Electronic mail.GHz - Gigahertz. Used often incorrectly to describe the speed of a processor. But with some 2.4 GHz processors faster than 3.6 GHz ones，it is clear that it is just a salesman trick.Load - Get data from a diskNibble - Half a ByteSave - Put data on a diskRAM – random-access memory(随机存取存储器)，the more the better.USB - Universal Serial Bus(通用串行总线，一种简化了插接多种附件的薄型插座)WWW - World Wide Web，part of the InternetII. Pre-reading1. Questioning and answering---What do you know about computer？●Electronic machine capable of performing calculations and other manipulations of various types of data，under the control of a stored set of instructions. The machine itself is the hardware；the instructions are the program or software. Depending upon size，computers are called mainframes，minicomputers，and microcomputers. Microcomputers include desk-top and portable personal computers.●A multi-function electronic device that can execute instructions to perform a task.●A device that accepts information，processes it，and supplies an output. A computer usually contains memory，a control unit，arithmetic and logical units，and a means for input and output.●a programmable hardware component that is controlled by internally stored programs and that can perform substantial computations (including arithmetic and logic operations) without human intervention. A computer typically consists of one or more processing units，memory units，and associated peripheral input and output devices.●Related to automation and electronic data processing. The Library of Congress commonly classes most computer-related books in HF5548，QA75-76，Z52，T385，and some TK ranges.●a machine for performing calculations automaticallycalculator: an expert at calculation (or at operating calculating machines)●A computer is a device or machine for making calculations or controlling operations that are expressible in numerical or logical terms. Computers are constructed from components that perform simple well-defined functions. The complex interactions of these components endow computers with the ability to process information. If correctly configured (usually by，programming) a computer can be made to represent some aspect of a problem or part of a system. If a computer configured in this way is give2. Discussing and sharing---How have computers changed our lives？Someday soon，if y ou haven’t already，you’re likely to plug into the computer network nation growing in our midst. Computer terminals，or small computers connected via modem (a modulator/demodulator circuit for encoding/decoding computer chatter) to ordinary telephone lines，should be as ubiquitous as the telephone itself. They’re a much more useful and humane tool than the phone，and with corporate America behind them the networks will be everywhere----changing our lives more than any technology since the automobile.Joining a computer network is the same as joining a community. Small systems are like villages，where new members are formally welcomed. The larger networks，the Source and CompuServe，for example，are cities-anonymous，full of life and events，but difficult to fit into.III. Reading1. Listening and reading to the recording of the text WHO AM I？Turn to page 18 and listen and read to the recording of the text. Pay attention to the pauses，pronunciation and intonation of the native reader.2. Reading aloud and underlining expressionsNow we are to read the text once again and underline all theexpressions in the text.

Reading，identifying and settlingAttention，please！It is time to skim the text one more time and identify the difficult sentences. Try analyzing the structures of the difficult sentences and discuss them among your group members. You may also put your questions to me for help.Chat (online)(在线)聊天To chat is to talk about ordinary things that are not very important. You can chat to one person or to many people. People also use this word now for parts of the Internet where we can talk with many different people at the same time. Usually，you chat on the internet in a chat roomor messaging service like AOL(American On-Line) Instant Messenger (AIM)，Yahoo Messenger，or MSN Messenger.4.

Warming up by talking about ITWhat is Information technology？Information technology (IT) or information and communication technology (ICT) is the technology required for information processing. In particular the use of electronic computers and computer software to convert，store，protect，process，transmit，and retrieve information from anywhere，anytime.II. Listening and writingTurn to page 21. Look at the pictures and listen to a conversation about different kinds of information technology or IT，discuss and write down in groups the advantages and disadvantages of each kind.III. Speaking and writingSuppose you and your partner are going to help choose computers for your school. Now talk about the special things each of the computer can do and write a report to your headmaster.IV. Reading，underlining and speakingIt is said that computers could be put into androids or robots. Read the text Andy—The Android，underlining all the expressions and think of the fun you could have！Expressions from Andy—The Androidpart of a football team，once a year，get together，play a football game，be as…as…，in fat，look like...，on the football team，run fast，think like a human，shout to (i)computer language，have a good shot for a goal，get second place，win the first place，have a new kind of program，improve one’s intelligence，create a better system，play against a human team，in a way，program…with…，make up…，after all，with the help of…V. Writing a letterSuppose you are an android. What would say to a spoiled child who would not do his homework？Write a letter to the boy.AndroidAn android is an artificially created being that resembles a human being. The word derives from Greek Andr- ‘man，human’ and the suffix-eides used to mean ‘of the species，kind，alike’ (from eidos ‘species’).The word droid，a robot in the Star Wars universe，is derived from this meaning. Some people maintain that，etymologically，the word android means resembling a male human and that a robot resembling a woman should logically be called a gynoid for sexist language to be avoided；however，this word is not commonly used.Unlike the terms robot (a mechanical being) and cyborg (a being that is partly organic and partly mechanical)，the word android has been used in literature and other media to denote several different kinds of man-made，autonomous creations:a robot that closely resembles a humana cyborg that closely resembles a humanan artificially created，yet primarily organic，being that closely resembles a humanAlthough essentially human morphology is not the ideal form for working robots，the fascination in developing robots that can mimic it can be found historically in the assimilation of two concepts: simulacra (devices that exhibit likeness) and automata (devices that have independence).The termandroid was first used by the French author Mathias Villiers de l'Isle-Adam(1838-1889) in his work Tomorrow’s Eve，featuring a man-made human-like robot named Hadaly. As said by the officer in the story，“In this age of Realien advancement，who knows what goes on in the mind of those responsible for these mechanical dolls.”Part Two: Teaching Resources (第二部分：教学资源)Section 1: A text structure analysis of WHO AM I？I. Type of writing and summary of WHO AM I？Type of writing This is a piece of narrative writing.Main idea of the passage Beginning as just a calculating machine in 1642 inFrance，the computer has been experiencingimprovement again and over again over 300years ormore，which has not only made it more beautiful andintelligent but also changed man’s life a great deal！Topic sentence of 1stparagraphI began as a calculating machine in 1642 in France.Topic sentence of 2nd paragraphNo one could recognize me after I got my new transistors in the 1960s.II. A chain of events showing the development of computera calculating machine in 1642 in France → an Analytical Machine in 1822 → a “universal machine.” in 1936 → the size of a large room → made smaller and smaller → getting new transistors in 1960s→ clever and quicker → a network in the early 1960s → talking to humans using BASIC in the early 1960s → brought into people’s homes in 1970s → Internet III. A retold version of the text WHO AM I？I，the computer，was a calculating machine in 1642 in France. Then Iwas built as an Analytical Machine in 1822，which was a technological revolution. I became a “universal machine” in 1936 to solve any mathematical problem. I was not very big at first then I became huge，the size of a large room before I was made smaller and smaller.Getting new transistors in 1960s I became clever and quicker. I was connected with other computers and turned out to part of a network in the early 1960s. Then I began talking to humans using BASIC in the early 1960s. In 1970s I was brought into people’s homes，and came the Internet.Section 2: Background information computersI. How Do Computers Work？Computer BasicsTo accomplish a task using a computer，you need a combination of hardware，software，and input.Hardware consists of devices，like the computer itself，the monitor，keyboard，printer，mouse and speakers. Inside yourcomputer there are more bits ofhardware，including themotherboard，where you wouldfind the main processing chipsthat make up the centralprocessing unit (CPU). Thehardware processes thecommands it receives from thesoftware，and performs tasks or calculations.Software is the name given to the programs that you install on the computer to perform certain types of activities. There is operating system software，such as theApple OS for a Macintosh，or Windows 95 or Windows 98 for a PC.There is also application software，like the games we play or the tools weuse to compose letters or do math problems.You provide the input. When you type a command or click on an icon，you are telling the computer what to do. That is called input.How They Work TogetherFirst，you provide input when you turn on the computer. Then the system software tells the CPU to start up certain programs and to turn on some hardware devicesso that they are ready for more input from you. This whole process iscalled booting up.The next step happens when you choose a program you want to use.You click on the icon or enter a command to start the program. Let’s usethe example of an Internet browser. Once the program has started，it is ready for your instructions. You either enter an address (called a URL，which stands for Uniform Resource Locator)，or click on an address you’ve saved already. In either case，the computer now knows what you want it to do. The browser software then goes out to find that address，starting up other hardware devices，such as a modem，when it needs them. If it is able to find the correct address，the browser will then tell your computer to send the information from the web page over the phone wire or cable to your computer. Eventually，you see the web site you were looking for.If you decide you want to print the page，you click on the printer icon. Again，you haveprovided input to tell the computer what to do. The browsersoftware determines whether you have a printer attached to yourcomputer，and whether it is turned on. It may remind you to turnon the printer，then send the information about the web page from your computer over the cable to the printer，where it is printed out.II. TelevisionOld portable televisionA television (also TV or telly) is a device (tool) with a screen that receives broadcast signals and turns them into pictures and sound. The word “television” comes from the words tele (Greek for far away) and vision (seeing).Usually a TV looks like a box. Older TVs had large wooden frames andsat on the floor like furniture. Newer TVs became smaller so they could fiton shelves，or even portable so you could take it with you wherever youwent. The smallest TVs can fit in your hand. The largest TVs can take up awhole wall in your house，and may sit on the floor，or be just a large flat screen that can be mounted on the wall. Many TVs are now made in wide screen shape like movie theatre screens，rather than old，more square TVs.A television has an antenna (or aerial)，or it has a cable. This gets the signal from the air，or cable provider. TVs can also show movies from DVD players or VCRs. TVs can be connected to computers and game consoles，usually through a kind of socket called “SCART”.III. Web or World Wide WebThe World Wide Web is the part of the Internet that contains web sites and web pages.It is not used to describe WebPages that are used offline where net services are not available，or no computer network exists - such as Wikipedia on CD. In this case no real physical site exists other than the place where the computer is. Blog and Wiki capabilities will also not be available because these require a communication with other computers.IV. RadioRadio is a communications invention. Though originally used to communicate between two people，it is now used to listen to music，news，and people talking. Radio shows were the predecessor to TV programs.V. DVDDVD most commonly stands for “digital versatile disk”. It can playvideo that is of a higher quality than a VHS tape.VI. Two kinds of DVDThey can also hold 4.7 GB of information as opposed to the 700 MB that a CD can hold. A plus of using a DVD for a video is the ability to have interactive menus and bonus features such as deleted scenes and commentaries.VII. EmailEmail (electronic mail) is a message，usually text，sent from one Internet user to another. Email is quicker than snail mail(mail) when sending over long distancesand is usually free. To send or receive an email，a computer with amodem and telephone line connected to the Internet，and an emailprogram are required. Email addresses are generally formated like this:login@server.(com or fr or org or uk or other).Some companies let you send and receive email for free from a website. Gmail，Hotmail and Yahoo！do this.VIII. HumanHere are two humans.A man is on the left and a woman is on the right. A human or human being is a person，like you. A male human is a man，a female human is a woman. If you think about all humans in the whole world，they are called humanity. In the past，people have also used man and mankind to mean all humans.Humans are called Homo sapiens by scientists. Humans are an animal species that belongs to the group called primates. Monkeys are primates too，but the primates most like people are gorillas and chimpanzees. Most scientists think that chimpanzees and humans came from a common ancestor by what is called evolution. Other animals even more like humans than chimpanzees once lived too，but they are now extinct.Human rights are those things that everyone deserves and the way they should be treated by other people.Section 3: Words and expressions from Unit 3 Computerscommonn. 1. an area of grassland with no fences which all people are free to use or a piece of open land for recreational use in an urban area (常用于专有名词中): Every Saturday Jean went riding on the village common. Harlow Common is very beautiful in winter.哈洛公园在冬天时风景很美。

高中英语_Unit3 Computers教学设计学情分析教材分析课后反思
教学设计因为本文是一篇说明文，讲计算机的发展和历史，为避免枯燥，提高学生兴趣和参与度，就想到了一个贯穿课堂始终的游戏：play chess.这是在看到人与机器人下棋这个图片时想到的。
全班分成六个组来博弈，每回答一个或多个问题可走一步或多步。
导入：利用时事新闻和人机下棋的图片以及机器人的图片快速导入课文。
阅读：快速阅读设了两个大的问题，一个是要学生找出文章的主旨大意；一个是以时间为顺序，理清文章的发展脉络。
细读分段分析，主要通过设置与文章有关的问题和填表，填空的形式，附以游戏：play chess 来进行。
评测练习：设置了两个问题，一个是小型的完型填空，与计算机有关，同时，也为后面的discussion 打基础。
另一个问题是summary,帮助学生回顾课文，同时检查自己在这篇文章中的学习情况。
讨论：先看一小段视频，《Robot》的一个片段。
然后，引领学生思考：With the development of computers,will they replace human being in the future? 进一步升华学生对本篇文章的学习,练习学生的表达能力和小组协作能力，增加学生的参与感。
作业：设置了一篇写作，介绍一个叫Allen的机器人，同时也是对课堂讨论的进一步思考。
学情分析我们是一所县级中学，学生的英语水平普遍不高。
学生压力大，学习策略和方法较为死板，习惯于题海战术，喜欢上课认真听老师讲课，较少主动的参与。
所以，应想方设法激发学生的兴趣，使其主动融进课堂学习。
效果分析Summary 和Cloze test 属于客观性题目，且与所学课文内容有关，学生表现积极，效果良好。
Discussion属于主观性题目，输出性较强，有些学生表现很好，积极参与，积极发言，而且思维清晰，条理清楚，能明确表达出自己的观点；有的学生可能在小组里讨论的很好，但却不敢站起来发言，或是汉语知道怎么说，英语却不会表达。

How much do you know about it? What is the Internet? The Internet is a large, worldwide collection of computer networks. A network is small group of computers put together. The Internet is many different networks from all over the world. These networks are called the Internet. Once you have learned to use the Internet, you can do a lot of interesting things on the World Wide Web. What is the World Wide Web? The World Wide Web has been the most popular development of the Internet. The Web is like a big electronic book with millions of pages. These pages are called homepages (主页). You can find information about almost anything in the world on these pages. For example, you can use the Internet instead of a library to find information for your homework. You can also find information about your favorite sport or film star, talk to your friends or even do some shopping on the pages. Most pages have words, pictures and even sound or music. What is e-mail? Electronic mail (e-mail) is a way of sending messages to other people. It’s much quicker and cheaper than sending a letter. If you want to use e-mail, you must have an e-mail address. This address must have letters and dots and an “@” (meaning “at”). Thisiswhatanaddresslookslike:**************.Write a message, type in the person’s e-mail address, then send themessage across the Internet. People don’t need to use stamps, envelopes or go to the post office since the invention of the Internet. Quick, easy and interesting—tha t’s the Internet! () 1. What is the Internet? A. It’s a big computer.B. It’s a small group of computers. C. It’s lots of computer networks.D. It’s the World Wide Web ()2. What does “ talk to your friends on the pages” mean? It means_____ A．you can talk to your friends face to face B．you can type your words in the computer and then send them to your friends across the Internet C. you talk to your friends through the same computer D. you go to your friends’ houses to talk to them () 3. Why do people like to use e-mail to send message to their friends andfamilies?Because_______ A. they don’t have to pay any moneyB.it’s faster and cheaper C. they don’t need to have stamps, envelopes or addressD. sending e-mail is interesting () 4. What does the “e” mean in e-mail? It means______ A. easyB. electricalC. electronicD.enjoyable B How toprotectchildren Webfans fromunsuitable material on-line while encouraging them to use the Internet has long been discussed in US. For some parents the Internet can seem like a jungle, filled with danger for their children. But jungles contain wonders as well as hazards and, with good guides, some education and a few precautions (预防措施) the wilds of the Internet can be safely navigated (航行). Kids have to be on-line. If we tell our kids they cant have access (进入) to the Internet were cutting them off from their future, said an expert. Most kids have started to learn to use search engines. Many of them are great for finding tons of interesting Internet sites, and they can also locate places where you might not want your kids to go. There are search engines designed just for kids. A certain software contains only sites that have been selected as safe. But themost popular that was to limit access would be to use what is known as a content screener (过滤). But this cant be wholly reliable, and the best thing parents can do is to talk to their kids and let them know whats OK or not OK to see or do on the Internet. Another way is that mum or dad is nearby when the child is surfing (扫瞄) the Internet. A few other tips: ●Dont put the PC in a childs room but keep it in an area where mum or dad can keep an eye on things. That also makes the Internet more of a family activity. ●Ask your child what he文档内容到此结束，欢迎大家下载、修改、丰富并分享给更多有需要的人。
