  设计主题
  Great scientists
  Reading :John Snow Defeats “King Cholera
  1.整体设计思路、指导依据说明
  本课时是必修5中Unit 1 第二课时(第一课时为Warming-up),为Reading部分。为培养和训练学生自主阅读的能力和技巧,结合说和写的能力,把整个学习过程分为三大部分。第一部分为Before-reading,主要培养学生根据主题进行预测的能力。第二部分为While-reading,为本课时的重点部分,以问题及提示,结合学习小组里的讨论,引导学生进行自主阅读。第三部分为After-reading,主要是给学生自由讨论和发言的机会,展示和巩固所学知识。
  自主阅读能够使学生在学习上拥有更多个性化的选择。通过对自主阅读的了解和训练,学生在一定程度上学会了自主运用和调整学习策略以改善自己的学习。自主学习能力的培养,提高了学生终身学习的能力。
  2.教学背景分析
  教学内容分析:
  本单元的中心话题是“Great Scientists”,介绍了一些伟大科学家如何以探索、钻研、无畏的科研精神验证未知的科学真理,使学生通过阅读科学家的故事,了解历史、学到知识、获得智慧、受到鼓舞。
  Reading部分介绍英国著名医生John Snow如何通过考察、分析、探究的科学方法,发现并控制了“霍乱”这种传染病。通过阅读课文,使学生感悟科学家的周密观察、勇于探索、认真分析的科学精神,学习并掌握有关的历史知识及语言知识,并了解公共卫生保健常识。
  学生情况分析:
  任教班级为本年级A层次学生,具有一定的英语基础,并有一定的自主学习能力。针对教材和学生特点以及教学要求,本课将侧重在培养学生的语言知识、语言技能、情感态度、学习策略和文化意识等素养的基础上使他们形成综合运用语言的能力。更重要的是要优化学生的学习方式,使他们通过观察、体验、探究等主动学习的方法,充分发挥自己的学习潜能,形成有效的学习策略,提高自主学习的能力。
  3.教学目标分析
  知识目标: 1. To learn about the stages in a scientific experiment.
  2. To learn about cholera.
  3. To learn the language through reading.
  4. To know about public heath medicine.
  能力目标:1. To train reading skills through self-access reading..
  2. To help the students express their ideas freely.
  3. To apply what they have learnt to practice.
  情感目标:1. To learn about how to do a scientific experiment.
  2. To learn how to co-operate in learning and how ot express their ideas.
  4.教学重点、难点分析
  教学重点:
  1. How to guide the students to learn the text in their self-access reading.
  2. Learn and use the language through reading. 
  教学难点:
  1. How to make the students more active in class.
  2. How to help the students to apply what they have learnt to practice.
  3. How to help the students make their self-evaluation after leraning.
  5.教学过程设计
  步骤1:Greetings and learning goals (1min)
  [设计意图]       
  进行阅读前指导,让学生明确本节课的学习目标,提高学生的自主阅读效率。
  Students are expected to
  1. acquire sub-skills of reading ---- predicting, skimming, scanning, generalization etc through self-access reading.
  2.learn to work together with their classmates and share information and ideas.
  3.  learn to assess on what the students have learnt and adjust their learning strategies.
  步骤2: Lead-in (5min)
  [设计意图]
  通过图片,根据SARS, AIDS 和 bird flu进行briainstorming,激活学生已有的知识和经验,思考该单元的中心话题并进行讨论和发言。充分尊重学生的自主性,调动学生的主观能动性,促进他们参与教学活动,同时引导学生了解疾病常识及日常预防保健知识。
  1) pictures reminding students of SARS in 2003, AIDS and bird flu.
  2) Brainstorming activity: What do you know about infectious diseases?     How do we prevent them from breat?
  步骤3:Pre-reading (4min)
  [设计意图]
  小组讨论,使学生初步了解得出科学观点所需的过程,为完成阅读奠定基础。在这一过程中,要留给学生发表自己观点和看法的机会。
  1. Do you know how to prove a new idea in scientific research?
  2. Discuss in small groups and put the following stages in a logical order.
  draw a conclusion         think of a method       collect results       
  map a question        find a problem          analyse the results
  find supporting evidence    repeat it if necessary
  3. Do you think there should be some more stages in proving a scientific idea?
  步骤4:Self-access Reading (20min)
  [设计意图]
  这一步骤为整节课的中心,教师引导并监控学生进行自主阅读。正如Brooks(1988)指出的那样:每个人阅读时都会对文本做出预测,关注的是经过自己理解的事件,并非只为获得意义而阅读。因此,为了帮助学生更快更好地进行自主阅读,教师设计了一个“self-aceess reading worksheet”。这个表格引导学生对材料进行预测和总结,并要求他们学习材料中的语言知识,获取新的词汇和表达。然后发表自己的观点和感想。但是,在他们明确了如何自主阅读之后,也鼓励他们设计自己的自主阅读工作表,以保证学生有选择和设计自己个人学习方式的自由。在整个阅读过程中,教师的角色转变为学生学习过程的调解员、中间人和促进者。他主要在学生阅读时提供帮助,在学生的自评和互评中适当提供意见和建议、提醒学生适时合作,寻求各种形式的帮助(如如何查阅字典和参考书等),鼓励他们继续往前走,学生自己才是整个过程中的主人.
  Before reading 部分是为了培养学生根据标题进行预测的能力,同时鼓励他们多方位思考。
  While reading部分是引导学生自主阅读,根据问题和提示培养整体阅读的能力、概括的能力、分析获取语言知识的能力等。
  After reading部分是让学生在阅读之后,通过小组讨论,提出自己的意见和看法,同时也是为了检测和巩固他们所学的知识。
  A Self-Assess Reading Worksheet
  Before reading
  What came to your mind when you first saw the title?
  While reading
  1. How did John Snow prove his idea? _______________________________________________________
  2. A brief summary of the passage (with not more than 40-50 words) _____________________________________________________________________________________
  3. New words, new phrases, and new structures I learn from the passage:____________________________
  ____________________________________________________________________________________________________________________________________________________________________________
  After reading
  My comments on what I have read (discuss in groups): _________________________________________
  步骤5:Presentation (10min)
  [设计意图]
  在这一步骤中,主要是让学生就他们通过自主阅读所获得的各项知识进行分享、展示。他们可以根据worksheet中的问题进行讨论、辩论、比较和自我纠错,也可以提出新的疑问和见解,由各小组长负责组织本组组员进行发言。每个成员都参与到活动中,都有机会最充分地展示自己的才能,同时也体现出了很好的分工合作。学生在体验、感知、实践、参与和交流中学习语言。
  步骤6:Homework
  [设计意图]
  课外作业可以帮助学生拓展并巩固课堂知识,又是对已知信息进行补充和延伸。让学生查找并欣赏知识点,既能避免枯燥的语法学习,调动学生学习的自主性,又能确保学生语言输出的正确性和有效性。
  1. Please find the new (or difficult) sentence structures and phrases in the text.
  2. Search the Internet (or ask for help from your parents, friends) for more information about how to prevent diseases in our daily life and write them down..
  课后反思
  1. 通过本课的学习,我们师生都对伟大科学家有了深刻的认识。
  2. 在教学的落实过程中,也遇到了少数学生有错误的思想,他们认为读书无用,高科技无用。
  3. 以前我们教学时重在讲解文中的知识点,总以为学生肯定知道不学习的坏处,现在我教学改为以学生为主体,让他们自己各抒己见,然后再加以引导。
