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。

2019年高中英语Unit3Computers单元小结教案(含解析)新人教版
Unit 3 ComputersIn a way computers can be considered a technological revolution. Because they have “artificial intelligence”， they can simplify difficult sums,“think”logically and solve any difficult mathematical problem. With the development of the network,computers have become very important in communication, finance and trade, and people all over the world can share their knowledge with others through the World Wide Web. Nowadays boys and girls use their mobile phones to surf the Internet. In order to explore the moon and Mars, computers have already been put into space rockets. In a word, computers can nearly deal with most problems in life. With the help of computers, the goal of human race will be turned into reality.However, just as a saying goes, “Every coin has two sides.” Personally, if you don't use computers properly, something uncomfortable will happen. For example, computer games programmed by operators are so wonderful that a lot of young people love them very much. They even play the games day and night without going to school. As a result, they failed in their lessons. Sometimes if you download something, viruses which can make your computer break down will arise.Anyhow, if you have a computer, your life will be filled with happiness.在某种程度上电脑可以被看作是一次技术革命。

2、Do you know in what ways computers are used today? Work out a list and compare it with your partner.你知道电脑今天用于什么方面？制定一个列表，同你的同伴比较它。
3、Look at these inventions. Can you put them in an order according to the time when they appeared? After reading the passage, check to see if you were right.看这些发明，你能安装它们出现的时间顺序给它们排序吗？读短文，看看你是不是正确的。
analytical machine解析机calculating machine计算机universal machine万能工作机Reading课文学习WHO AM I?我是谁？Over time I have been changed quite a lot. I began as a calculating machine in France in 1642. Although I was young I could simplify difficult sums. I developed very slowly and it took nearly two hundred years before I was built as an analytical machine by Charles Babbage. After I was programmed by an operator who used cards with holes, I could "think" logically and produce an answer quicker than any person. At that time it was considered a technological revolution and the start of my "artificial intelligence". In 1936 my real father, Alan Turing, wrote a book about how I could be made to work as a "universal machine" to solve any difficult mathematical problem. From then on, I grew rapidly both in size and in brainpower. By the 1940s I had grown as large as a room, and I wondered if I would grow any larger. However, this reality also worried my designers. As time went by, I was made smaller. First as a PC (personal computer) and then as a laptop, I have been used in offices and homes since the 1970s.随着时间的推移，我已经发生了很大变化。

was called “a universal machine” in 1936，as I could solve any mathematical problem.In the 1960s，I was given a family connected by a network，so that I could share information with others and we could talk to each other.In the 1970s，I was brought into people’s homes.T：You are so quick-minded that in such a short time you could find out all the answers to the questions.Your mind really works like a

Unit 3 Computers 教案整体阅读教案及反思
Unit 3 Computers 教案整体阅读教案及反思第一步引入话题1. Show students the pictures of an abacus, a calculator, a huge computer, a notebook and a PC, ask: “If I am a math teacher, which can help me most?”2. Write the expressions of giving opinions on the blackboard. Giving opinions I think that... In my opinion... I believe that...3. Ask students to give their opinions, remind them of using the expressions of giving opinions.4. Ask students to discuss what these items have in common, and then rank them according to the time of their appearance.5. Ask some of the students to talk about what they know about computers.6. Ask students to discuss “How have computers changed our life?”, a nd then have some of them give their answers, using the expressions of giving opinions.第二步猜想文章的内容（个人自由发言）1. Ask students to look at the pictures and guess what the passage might be about.2. Ask one or two students to give their opinions.第三步阅读文章 Who Am I?1．Give students 2 minutes, and ask them to scan or skim for the answers to the following questions:(Before students read the passage, tell them that attention should be paid to the hints of the time.)(1) What is the main idea of the passage?(2) What happened to computers in 1642？(3) What happened to computers in 1936?(4) What happened to computers in 1970s?(Questions on page 19)2．Give students 5 minutes to read the passage carefully, and answer the following questions:(1) Who was the first person to describe how the computer was made to work?(2) What did he make and what did itdo?(3) Who was the next important person to design computers? 第四步学习“拟人化”（小组合作学习）Ask students to go over the passage, in groups discuss who the speaker is in the passage, and on page 18 write down three sentences from the text to support their ideas.Check the answers with the students.(同学可能会找这三个句子时感觉到有困难，因此可以依据实际状况向同学供应必要的提示或者例子)Sum up:Personification means to treat something as if it were human or had human qualities.Personification is one of the most effective ways of using words figuratively.第五步学习“时间挨次”（小组合作学习）1. Ask students:“How is the passage organized?”(If the students can not answer the question, draw their attention to the appearance of different years.)2. Ask students to finish Exercise 2 in Comprehending on page 19, complete the “Timeline”.3. Ask students to ex-change their own answers in groups, and then raise questions if they have any.4. Sum up: chronological writingChronology means to describe things in order of time.Chronology is often used in recounting an event or describing the life of someone. It is an effective way to make a mass of things clearer.第六步口语训练──及时间挨次复述计算机的进展史1. Have students get prepared in 2 or 3 minutes and then retell the development of computers in your own words, using chronology.2. Ask some of the students to retell the text.第七步作业布置Go over the text, and try to understand the text.Finish Exercise 1 in Learning about Language on page 19. </p。
