module 6 book i the internet and telecommunicationsreading教案一、课程分析：学习内容：reading and vocabulary这个模块围绕the internet and telecommunications这一话题，开展听、说、读、写多种教学活动。本课是高一必修模块6的阅读课，是模块整体教学的重要环节，是学生获取信息，输入知识的最主要的载体。本模块课文重要介绍了因特网、因特网的兴起、万维网、万维网的发明。课文运用了大量的数据和专业用语，出现了较多定语从句，句子较长，对学生的语言阅读能力提出了更高的要求。但文章的结构较明显，较易抓住课文主要脉络结构。处理本阅读课文，主要采用任务型教学模式，即要让学生通过语言实践活动来体验语言，从而提升自己综合语言运用的能力。学习重点1）让学生理解课文的内容，了解因特网和万维网，深入了解它们的兴起和发展进程。2）训练学生用英语获取信息、处理信息、分析问题和解决问题的能力，提高学生独立思考和判断的能力。另外，课程的设计与实施有利于学生优化英语学习方式，使他们通过观察、体验、探究等积极主动的学习方法，充分发挥自己的潜能，提高自主学习的能力，要有利于学生学会运用多种媒体和信息资源，拓宽学习渠道，形成具有个性的学习方法和风格。3）理解和掌握课文的语言点，并能用英语解释新的语言点：consist of; become possible for sb. to do; become known as; allowto do; come up with 学生每学一课，首先要掌握一定量的词汇和固定用法，通过阅读，掌握一定量的词汇并且提高其阅读理解能力，符合新大纲的要求。学习难点）使学生养成科学的阅读习惯，提高阅读理解能力和语言水平。 ）使学生学会理解、提取和筛选文章中的信息，并灵活运用于语言实践中，达到语言实践能力的扩展与提高。依据课程标准，在吃透教材基础上，我觉得本课是学生对于因特网和万维网的了解的程度从知识的浅面上升到情感态度的一节课，通过讨论形成合理正确使用网络的价值观。二、学情分析高中英语学习兴趣培养和学习习惯形成的关键阶段就是高一。学生们渴望获得知识的同时也希望在英语学习过程中享受到乐趣，不愿意老师死板地讲解字词及语法。对周围事物的敏感导致他们对很多事情有自己的观点和看法。本模块的话题是与生活密切相关的网络，学生们不会无话可说，因此只要引导得当，学生们积极配合，就一定能完成教学任务。学生现在水平还不能流利自如的驾驭这门语言，表达错误是难免的，但是一定不能挑剔，要鼓励学生表达自己观点，大胆说。三、设计理念坚持“以学生为本”的宗旨，教师的引导始终渗透到课堂教学之中，创设情景，激发情意，力争使每一位学生都参与到课堂中去，动眼看、动口议、动脑思、动笔写。体验为红线，思维为主攻。教学设计始终围绕本科的中心话题，最终完成三维教学目标。各种练习的设计都遵循“由简到繁、由难及易”的原则，为有困难的学生搭好梯子，让有能力的学生“跳一跳”摘到果子。重视学生个性与创新意识的培养，并给予学生充分表达自己的机会。创设多种情境激发学生的兴趣，只有让学生真正有了参与的欲望，才能点燃他们的思维火花。任务型活动策略。在做中学，在做中练，在做中巩固，使课堂教学产生事半功倍的良好效果。四、学习目标通过阅读，能理解文章大意，掌握文章结构及层次。根据课文内容共同或独立完成相关练习。能运用所学的内容写一段4050字的描述性文字。五、教学流程课前准备让学生通过课前查阅资料，了解因特网和万维网的相关信息，并尽量争取能用英语表达这些信息。新课导入（通过提问和讨论）通过展示学生常用的网络工具快捷键图片来调动学习兴趣，引出因特网和万维网的话题。）为有效地发展学生的思维和表达能力，采取课标所提倡的思维训练活动。即，在开展阅读活动之前，采用图表的方式帮助学生组织信息，表达观点，开展阅读活动。 学生就本课主题，参考这些问题，完成下面的表格的第一部分，第二部分留待读完课文后，以填空的形式进行填写。how much do you know about the internet?how much do you know about the world wide web?things you have known alreadythings you didnt know before点评：通过师生对话激活相关词汇和学生对网络的已有知识。形成一个信息包，激活他们的思维，为下面他们主动参与主题教学活动打下基础。新课呈现（）明确学习目标：(多媒体显示)t: look at the aims of this class. firstly, understand the whole passage. secondly, complete the exercises according to the text. thirdly, write a short essay.点评：这是任务型的课堂教学所特有教学环节，任务型的课堂教学一开始就呈现出任务，让学生从课堂教学一开始就明确知道自己要完成的任务，然后在任务的驱动下去学习语言知识，进行技能训练，这样的学习过程是任务驱动的过程，有利于强化学生的兴趣和动力，同时有利于体现任务的真实性。任务型的教学固然是完成某项或多项任务，但完成任务不是教学的目标所在，达成目标的过程才是重要的内容。（）布置任务：）复习单词 t: now, lets review the words. turn to page 112. read the words together. (学生齐读单词，个别词读音不准的情况下，老师及时纠正。)点评：适时的复习，可以帮助学生达到温故知新的目的。老师及时帮学生纠正发音错误，可以避免学生加深错误印象。t：next, well do another job. look at the screen. fill in the blanks with the words in the box. tell me the answers one by one. access academic create defense military source viathey built a _ against flooding.the first “web browser” allowed computer users to _ documents from other computers.there used to be a _ base in the region.a novelist _ characters and a plot.he flew to new york _ hong kong.the internet is the biggest _ of information in the world.professor watson is leaving the _ world to take a job in industry.点评：同是单词复习，这样的练习，有利于学生在理解词义的基础上，将其熟练运用。）速读课文，根据课文内容回答问题。(题目出现在卷子上)t: class, lets come to the text. its a text introducing the internet and the world wide web which is used for short. read the text loudly and answer the following questions. then, check your answers with your group numbers.what is the internet?how did it start?what is the world wide web?who invented it?点评：这些问题比较有代表性，能帮助学生把握文章的主旨大意题。对于那些自主完成有一定难度的学生，可以让他们在读完课文以后，互相交换意见，通过讨论，得出正确答案。这种生生交流，能促进学生间的良好合作，不同层次学生的积极参与能带动课堂，通过自主探究找到答案依据，能给学生带来成功的喜悦。在交流中，学生对课文的主要框架结构已基本了解。）判断正误练习。t: next, i want you to decide “t” or “f” according to the text. listen carefully.there are millions of pages of information on the internet.
