高中课型课例交流与研究ComputersNSEFC Module2 U3（中学篇稿件）高中课型课例交流与研究ComputersNSEFC Module2 U3一 教学课型：综合技能课（reading，speaking and writing）二 教材分析1 教学内容（教学内容见文末）2 教学内容分析及教材处理本单元的中心话题是计算机，内容包括计算机的发展历史，计算机的应用，各种信息技术载体的介绍，以及智能机器人的发展。而本堂课由reading（机器人Andy自述），speaking(讨论设计和描述机器人) 和writing （用纸笔设计和描述智能机器人）三个部分构成，是建立在学生对课文有了一定的了解和理解的基础上，要求学生能够结合相关的话题进行语言的输出，具有一定的难度。但教师如果能前期做好知识铺垫，课堂上利用学生对智能计算机的兴趣，通过阅读，讨论，写作几个步骤肯定能使学生设计好和描述出他们心目中的最佳智能机器人。为了使课堂更加富有梯度感，层次感，笔者把课文中写作用的范文省略，而采用Doraemon（机器猫）这个艺术形象进行代替，作为从读 到说和写的过度。为了激发学生的兴趣和参与积极性，笔直还设计了导入时变形金刚片段赏鉴；增加了写后的当堂呈现-说出机器人，和让学生共同参与的当堂评价。3 教学目标（1） 通过阅读，了解机器人的相关特征，掌握从课文中获取所需信息的方法和技能， （2） 通过小组讨论和共同写作，激发学生的思维，培养学生创造性思维, 使学生掌握知识的模仿和迁移。并使学生进一步了解写作的过程，培养他们对写作的兴趣和信心。（3） 在交流中培养学生的合作，探究，同伴互助的学习策略。（4） 通过共同参与评价，让学生品尝学习成功的快乐和培养思考、总结、归纳等学习能力。4 教学重点和难点（1） 组织学生讨论设计智能机器人。（2） 组织学生写作并描述智能机器人。三 教学设计1 总体思路教师首先利用多媒体展现变形金刚片段，引出智能机器人的话题，激活学生的思维。接着通过“读”（要求学生阅读机器人Andy的第一人称叙述它参加足球比赛的经历、感受和想法并找出有关Andy的相关信息）和“说”（学生小组讨论，模仿Andy的信息表，设计自己机器人的信息表）顺利过度到“写”（要求学生以小组为单位设计、写作描述机器人）,然后再“说”（口头描述和展示自己设计的智能机器人，达到有效使用语言的目的），最后，让每个学生参与自评和互评，选出最佳设计奖和最佳写作奖。这几个部分内容一步一步递进，步步相扣，过渡自然。让学生在完成教学设计任务的同时，不仅掌握语言知识的各种技能，还感受到学习知识的快乐。2 教学设计Step1. lead-in 1. Greeting(1minute before class) Show students several funny pictures to make them laugh and then ask (1)Are you happy? (2)Do you want to make me happy?

Group discussion1 The teacher Talks about her own android using the information belowName: DoraemonSize: as big as a 10-year-old childJob: a kind of toy(玩具)Ability: can think and speak Appearance: like a catCharacter: clever, helpful, have magic power2 Android DIY Ask the students to finish ID card of their own androidName: Size: Ability: Appearance: Character: (设计说明)此环节先由教师以自己最喜欢的Doraemon这个智能机器人 的身份证为辅助，详细描述Doraemon ，为学生下一步的写作树立一个范本。然后要求学生讨论完成他们的智能机器人的身份证填写，为写作提供详细的素材。在此，笔者用Doraemon代替教材最后的写作用的范文，并且提前到此处使用，是为了使课堂更贴近学生；使写作更具有梯度性。这个环节中的教师描述，应注意让学生注意文章的描述点。Step5. Pre-writing 1. A creative composition contest about the robot designing will be held in our school. Ask the students to compete for the best writer and best designer ,who will be awarded.2. Show the students the passage structure My Dreamy Android Part1: Brief introduction (name, looks, etc.)Part2: What you wish it to do (function)Part3: A fancy/wonderful ending3.

Please let your imagination fly!(设计说明)运用 “作文竟赛”和 “奖品”, 激发学生参与的积极性，为顺利进行写作打好情感基础。然后让学生了解描述机器人的写作结构和要点。而且提供可能要用的词汇,并且鼓励他们尽可能地多运用所学词汇。为学生打好语言基础，使他们有东西可以模仿，不会言之无物。Step6. While-writing The students work in groups of four. They should not only design the android but also describe it. The students who are good at drawing may help to design, and the students who are good at writing may write. Others may check and correct the mistakes. They help each other for the same purpose-their dreamy android. (设计说明)此环节要求学生运用所获得的语言信息进行有效输出，培养利用有效信息写作的能力。通过互相帮助,共同完成机器人的设计和描述，培养他们共同合作，互相学习，一起进步的意识。Step6. Post-writingAsk the students to present their design then describe their dreamy android. While one group is speaking, others are asked to fill the Evaluation Form according to the directions. At last, the teacher lead the students to a conclusion which group is the winner.Evaluation Form(评价表)GroupInformation(AC)Demonstration展示，呈现(AC)Cooperation合作(AC)Total Score总分 (AC)PassagePicture1234A Excellent(极好的) B Satisfied(满意的) C Needing improvement(需要改进)Directions:1.

HomeworkImprove your compositions and pictures and then put them up at the English Corner at the back of the classroom.(设计说明)教学成果的修改和展示更能激励学生，提高他们学习的积极性。让学生更多层面地感受学习的成功和快乐。附教材内容： ANDY-THE ANDROID Im part of an android football team. About once a year we are allowed to get together to play a game of football. Im as big as a human. In fact, I look like one too. On the football team Im a striker so I have to be able to run very fast. My computer chips help me to move and think like a human. For example, I have learned to signal to my teammates in computer language to give me the ball when I am open and have a good shot for a goal.My first football competition was in Nagoya, Japan several years ago. Last year our team went to Seattle, Washington in the USA. We won second place. Personally, I think the team that won first place cheated. They had developed a new type of program just before the competition. So we need to encourage our programmer to improve our intelligence too. We are determined to create an even better system. In a way our programmer is like our coach. She programs us with all the possible moves she has seen while watching human games. Then she prepares reliable moves to use if a new situation arises. In this way I can make up new moves using my “artificial intelligence.” After all, with the help of my electronic brain which never forgets anything, using my intelligence is what Im all about.1. Read the passage carefully and fill in the file for AndyName _Appearance_Size _Character_Ability_Job_2. Create your own android. Fill in the file, and compare with your partner.My own Robot Name _Appearance _Size _Character _Ability _Job _3. Write a description of your android and what it can do. You may draw a picture of it if you wish. Use your notes and the following sample passage to help you. My Android I would like to have an android that can do all my jobs around the house. This means that it should clean the house, mop the floor, cook the dinner and deal with telephone calls. It should also watch over my naughty niece, who comes to my house very often. Whenever she comes, I have to look after her, and sometimes help her with her homework. I hope my android will be programmed to do homework and not make mistakes. In that way, my niece will not spoil my free time and I can go out with my friends. I dont mind what my android looks like, but it must be able to talk and tell funny stories to my niece.
