The kings favourite game was chess. 2One day, a wise old man came to the palace and the king challenged him to a game. The king promised the old man, “You can have any prize if you win the game. 3The old man said, “If I win the game, Id like one grain of rice for the first square of the chessboard , two for the second , four for the third ,and then double the amount for each of the rest of the squares.” 4“Is that all?”asked the king. “Wouldnt you like gold or silver instead?” 5“No, just rice.”replied the old man. 6The king and the old man played the game for a long time. 7Finally, the old man won. So the king ordered his men to collect a bag of rice. He put one grain on the first square, two on the second, and so on. 8The king quickly realized the problem-even with all the rice in the country , he would still not have enough rice to put on all the squares!1教学内容分析教学内容分析 本课时是沪教 2011 课标版 8 年级上学期第二单元, 话题为 Numbers , 阅读课型。阅读材料的体裁为故事阅读。故事讲述的是国王在兑现自己的承诺时发现，智者提出在棋盘上摆放米粒的要求，听起来不起眼，实际却是如此遥不可及。学情分析学情分析 经过初中阶段第一年的学习，学生在英语学习技能方面，如阅读技能有一定的积累。本课时故事的内容涉及的乘方问题，也是 8 年级学生在该学期数学课中学习的内容。这个故事不仅适合该年龄段的孩子的水平，且趣味性强，无论从英语语言理解的角度，还是从挑战数学趣味题的角度都将对学生产生一定的吸引力。本次授课班级的学生语言能力较好，乐于展现自我，在表演方面的兴趣及才能比较突出。教学目标分析教学目标分析语言知识目标语言知识目标: 学生能够理解故事情节发展中的几个关键点：*promise the old man any prize, *double the amount,*.even with all the rice in the country, he would still not have enough rice to put on all the squares! 语言技能目标语言技能目标:1. 借助图片、单词以及文章的伏笔，猜测故事的发展;2. 通过扫读，快速找寻故事的三个要素：Who？When？Where？3. 读懂故事的内容并通过关键词和图片的辅助，完成故事的复述与表演；24. 续写故事可能的结局。教学重难点分析教学重难点分析教学重点教学重点: 能够辨别出故事情节发展的几个关键点，并且能够正确理解它们对故事的后续发展起到的推动作用。教学难点教学难点: 1. 正确理解故事的情节，并能深入细读文本，读懂故事中导致出人意料的结果的精彩文段；2. 发挥想象力，续写故事的结尾。教学设计思路教学设计思路对于故事体裁的阅读教学的思考对于故事体裁的阅读教学的思考 英语阅读教学促进语言素养的形成，是英语学科素养培养的重要环节。在选择这一课时进行设计时，我做了以下几点考虑：1. 结合阅读材料的特点，进行相应的技能训练或拓展。故事阅读由于情节跌宕，语言表达丰富，深得学生的喜爱。结合学生的特点，在输出部分采用猜测可能性结局、表演故事等方法巩固并拓展所学内容；2. 阅读的目的不仅在于答题，更在于获取信息。在读后的检测部分，尽量设计成活动或任务，形式上避免过多地采用回答问题或判断题。3. 关注文本的教学在阅读教学中的作用。深入挖掘文本的内涵，分析人物的话语，从而达到帮助学生理解文章的目的。本课时教学规划本课时教学规划以故事情节发展为主线，结合故事细节阅读，引导学生逐步理解故事发展的起因、高潮和结果；通过人物话语分析，理解为造成故事的结尾峰回路转所铺垫的精彩伏笔。结合阅读材料的特点，设置拼图阅读、扫读、细读、表演、编写故事等多角度任务，把多种技能有机地结合在一起，促进学生的阅读能力的提高以及发散性思维能力的形成。3教学过程教学过程Step 1 Lead-in1. Play a game of numbers: Listen and react Ask if Ss are good at maths and if they like working with numbers? Tell them they are going to challenge themselves in this class. Explain the meaning of challenge at the same time. Tell Ss they are going to listen carefully and react. Eg, Who is 13 years old ? Please raise your left hand. Who is over 1.60 metres tall ? Please raise your right hand. Who is in Class 3, Grade 7? Please raise both of your hands. Who lives on the 4th floor? Please clap your hands. Who gets to school before 7:30 ? Please stand up.设计目的：设计目的：在课的开始环节设置 Listen and react 的游戏，从内容上复习与本课相关的 numbers，为下一步进入一个与数字、数学相关的故事阅读建立链接。从心理学的角度，游戏可以活跃气氛，减轻学生的紧张感，并帮助他们集中精神，更快地进入本课的学习。2. Watch the video of the beginning of the storyTell Ss they are going to read a story about numbers. Have them watch the beginning of the story. Ask them a question : What did the king promise the old man? After watching the video, have Ss answer the above question. Write down the phrase: promise the old man any prize on the blackboard. 设计目的：设计目的：使用视频导入故事的开头部分，学生带着问题观看。教师顺势利用学生的回答 He promised the old man any prize , 板书部分精彩情节。4信息技术应用策略：用录频软件制作的视频信息技术应用策略：用录频软件制作的视频 所用素材由学生自行绘画加插配音。3. Vocabulary study Teach some vocabulary: grain, a grain of rice, chess, chessboard and square. Help Ss to understand the word square may have two different meanings (广场；正方形). Have Ss count how many small squares there are in the picture on the ppt. Show the ppt with just three pictures: a grain of rice, a chessboard and a picture of the king and the old man playing chess. Tell Ss there was a king, a wise old man, a grain of rice and a chessboard in the story and the king promised the old man any prize. Ask them what might happen later.设计目的：设计目的：词汇教学环节扫除一部分的生词障碍。在这个环节中穿插了两个小插曲: 首先，在 square 一词的教学中呈现一幅由多个小正方形组合而成的大正方形。这样做的目的是在学生脑海中埋下伏笔：事物的内涵与它们的外表可能是不一致的。其次，在单词教学过后，为进入故事的阅读抛出一个悬念：围绕着故事中的国王、智者、米粒、棋盘和国王的承诺，会发生什么样的故事呢？信息技术应用策略：信息技术应用策略：PPT 动画功能动画功能 设定无关的图片消失。展示与故事发展密切相关的图片， 插入设问，引发学生思考，猜测故事的情节。Step 2 Reading1. Jig-saw Reading1) Have Ss work in groups, read the sentences and put them into the right order. Tell them to underline the evidence. 2) Check the answer and have Ss talk about the evidence.设计目的：设计目的：故事体裁的阅读材料有明显的情节发生顺序，适合设计拼图阅读的5小组活动。寻找支持段落排序的依据, 目的在于培养学生理清语篇中的逻辑关系的能力。信息技术应用策略：信息技术应用策略：PPT 的使用的使用 PPT 课件展示完整的文章，圈划排序的依据，展现上下文 的逻辑关系：如时间、词汇的关联等。2. Match the main ideas with different parts of the story.1) Have Ss skim the whole story again and match the main ideas with different parts. 2) Have Ss read the main ideas aloud by themselves and try to remember them .设计目的：设计目的：在前一环节的拼图阅读中，学生获取的信息相对比较有限。因而在这里设计一个整体阅读，完成段落与段落主旨大意的匹配，再要求学生朗读并记住每一个段落的大意。为读后的复述活动做了输入的铺垫。3. Read for the main elements of the story1) Have Ss scan Paragraph 1-3 and find out the elements: Who? When ? Where?2) Get Ss read the rest of the story and fill in the blanks of the details of the story.3) Ask Ss what they think about the wise old man.设计目的：设计目的：本部分设计主要想达成两个目的：1) 进行扫读、细读两种阅读技能训练；2）承上启下，在本环节结尾部分设问: What do you think of the old man? 引发下一环节讨论老人的性格特征及其智慧语言的活动。4. Read more about the old mans words1) Read Paragraph 4-5 and find out “What did the old man want for his prize?”2) Read Paragraph 3 and find out “How did he want his prize?”63) Explain to the Ss why the total amount of the rice was a large number. 设计目的：设计目的：这部分活动主要针对智者的语言进行细节阅读与分析。按照实际教学的需要把后两段提前进行细读。老人想要得到的奖品是米。从而讨论他回答“No，just rice.”的真正用意。这句话隐含了智者用 just 一词来暗示国王：比起金子，银子来，好像米粒显得不那么贵重; 而且似乎摆满一个棋盘也需要不了太多的大米。但恰恰是这句 just rice 成功地迷惑了国王，让国王落入陷井中。 How did the old man want his rice ?是故事转折的关键所在。学生在此处如能理解 double the amount 的意思是每次双倍计算的数量，就能明白故事的令人惊讶的峰回路转的结局。因为智者提出 double the amount 的做法，使得米粒的数量成倍地疯涨。最终导致国王用尽全国的米也无法满足智者的要求。此处借助纳米黑板的复制、拖动等功能，进行师生互动，形象生动地展示米粒在棋盘上摆放的规则。信息技术应用策略：信息技术应用策略： 1) PPT 的使用的使用 问题的设置层层递进。设置不同的标记逐一出现，突显智者 语言的别具匠心之处。 2) 纳米黑板纳米黑板使用纳米黑板的复制、拖 动功能展示米粒摆放的规则。清晰展现为何小数目最终 会演变成天文数字。7 3) Flash 动态图片动态图片 用于解释米粒环绕地球摆放足以绕地球 7500 圈。Step 3 Post-reading1. Retell the story by looking at the pictures and the key words.2. Act out the story.3. Imagine an ending for the story.设计目的：设计目的：在前面的阅读活动中，设计段落大意的填空、记忆等活动为学生理解课文、复述故事打下了基础。在这部分读后活动中，设计看图复述课文，是前一轮活动的进一步延伸；表演环节让学生加深对课文的理解，发挥同学们的所长，让他们体验英语学习的趣味性；最后，创设故事可能性结局的活动让他们发挥想象力和创造力，主动参与语言实践。信息技术应用策略：信息技术应用策略： 1）四格漫画四格漫画 再次利用制作视频的图片做成四格漫画，加插关键词， 辅助学生复述故事。 2）布景图布景图 简单布置成表演时的背景，创设情境以增加表演的现场感。8Step 4 SummarySummarize what we have learned in this class. Ask Ss what we can learn from the story: Things may not be the same as they appear to be，so we may have to be careful. Step 5 Homework1. Imagine an ending for the story “The king and the rice”and write it down. 2. Search the Internet for more wise stories and tell them to the class.
