Unit 2 CloningPart 1 Teaching Design第一部分教学设计Period 1 A sample lesson plan for reading(CLONING:WHERE IS IT LEADING US?)IntroductionIn this period, after the warming up, students will first be guided to pre-read the text by questioning and answering. Then they shall read aloud to the recording, read for forms, read for the type of writing and summary of CLONING:WHERE IS IT LEADING US?. The students will be asked to copy useful expressions and make sentences, read and transform and read the text again to draw a diagram of it and retell the story with your own words. The period will end in students learning more about Dolly. ObjectivesTo help students understand the text’s forms and contents and learn about cloning To help students communicate on the topic in focus with the words, expressions and structures learned in this unitFocusAidsMultimedia facilities, tape-recorder, photos, diagramsProcedures1. Warming up by leaning the word “clone”clonen.1. A cell, group of cells, or organism that is descended from and genetically identical to a single common ancestor, such as a bacterial colony whose members arose from a single original cell.2. An organism descended asexually from a single ancestor, such as a plant produced by layering or a polyp produced by budding.3. A DNA sequence, such as a gene, that is transferred from one organism to another and replicated by genetic engineering techniques.4. One that copies or closely resembles another, as in appearance or function: "filled with business-school clones in gray and blue suits" Michael M. Thomas. v. cloned, clon·ing, clones1. To make multiple identical copies of (a DNA sequence).2. To create or propagate (an organism) from a clone cell: clone a sheep.3. To reproduce or propagate asexually: clone a plant variety.4. To produce a copy of; imitate closely: "The look has been cloned into cliché" Cathleen McGuigan.2. Pre-reading by questioning and answeringWhat is cloning? We define cloning as production of a cell or organism with the same nuclear genome as another cell or organism.Cloning is the process of creating an identical copy of an original. A clone in the biological sense, therefore, is a single cell (like bacteria, lymphocytes etc.) or multi-cellular organism that is genetically identical to another living organism. Sometimes this can refer to "natural" clones made either when an organism reproduces asexually or when two genetically identical individuals are produced by accident (as with identical twins), but in common parlance the clone is an identical copy by some conscious design. Also see clone (genetics).The term clone is derived from the Greek word for "twig". In horticulture, the spelling clon was used until the twentieth century; the final e came into use to indicate the vowel is a "long o" instead of a "short o". Since the term entered the popular lexicon in a more general context, the spelling clone has been used exclusively.3. Reading aloud to the recordingWhole language teachers affirm that reading aloud teaches you the students about language in a way that silent or independent reading never can.Reading aloud to the tape helps you the students develop and improve language skills -- reading, writing, speaking, and listening. And since you the students listen on a higher level than you read, listening to other readers stimulates growth and understanding of vocabulary and language patterns.So why not hurry to listen and read to the tape-recording of the text we are going to learn today?4. Reading for formsRead the text again to: cut/ the sentence into thought groups, blacken the predicates, darken the connectives and underline all the useful expressions.5. Reading for the type of writing and summary of CLONING:WHERE IS IT LEADING US? Determining the type of writing will help you determine the author’s topic (subject), purpose (why he is writing), style (how he should write) and tone (his attitude towardhis subject - supportive, condeming, objective, etc.)It is important to find main ideas when reading. Main ideas help you remember important information. The main idea of a paragraph tells the topic of the paragraph. The topic tells what all or most of the sentences are about. The other sentences in the paragraph are called details. Details describe or explain the main idea. Read the text to find the main idea.6. Copying and making sentencesYou are asked to copy all the useful expressions into your notebook after class as homework. You may make your own sentences with each of these expressions.7. Reading and transforming8. Reading the text again to draw a diagram of it and retell the story with your own wordsWriters structure, or organize, their writing in many different ways. Recognizing the way in which a text has been organized will help you understand its meaning more fully.9. Closing down by learning more about DollyTo end this class, let’s get to know more about Dolly.Celebrity Sheep Has Died at Age 6Dolly, the first mammal to be cloned from adult DNA, was put down by lethalinjection Feb. 14, 2003. Prior to her death, Dolly had been suffering from lung cancer and crippling arthritis. Although most Finn Dorset sheep live to be 11 to 12 years of age, postmortem examination of Dolly seemed to indicate that, other than her cancer and arthritis, she appeared to be quite normal. The unnamed sheep from which Dolly was cloned had died several years prior to her creation. Dolly was a motherto six lambs, bred the old-fashioned way.。

四、学习者特征分析高中年龄段的学生对周围的事物较为敏感,有自己的观点和看法,他们不满足于教科书上的知识,想获得更多的信息。
在英语学习上,他们不只是想把英语作为一门死记硬背的课程来学,更希望能学到知识性和趣味性兼有的内容,从英语学习中获得更多的知识和能力。
因此,结合学生的实际情况,课前让学生在网上查询有关“多利羊”的信息。
对克隆有一个宏观的认识。
激发学生兴趣,让学生主动学习,学有所获。
合作学习是一种教学形式。
他要求学生在一些几个人组成的小组中一起从事学习活动,共同完成老师分配的学习任务。
在每个小组中学生们通常从事各种需要合作或互助的学习活动。
学生们一起学习,获得知识,并且当他们获得成就时,他们变得非常投入,变得关心他人和他人的学习。
他们在一起进步的过程中,关心他人和他们的成就,结成紧密的学术关系和人际关系。
五、教学过程Step 1 RevisionMatch the words with the Chinese meaning and then read the words together.Exact undertake pay off breakthrough objectobtain moral in favor of复习上节课所教新词有助于学生接下来高强度的阅读。
在上课开始大声朗读在一定程度上能提升学生上课的兴奋度。
Step2 Lead inPresent the scenes of the movie --<Jurassic Park>and some pictures and tell what the difference is.(some are natural clone and the others are man-made clone)本文是一篇说明文,所以在导入部分需要充分引起学生的兴趣。
对于充满好奇心的高中生来说,介绍恐龙和现代的克隆动植物能激发学生求知的欲望,同时引发思考:克隆是什么呢?克隆是好的还是不好的呢?从而引起下来的话题,进入我们的课文学习。
Step3 Fast readingRead the text and give the main idea of each para. using a few words.主要了解文章各段大意,对本文有一个初步的了解。
此任务也训练了学生通过快速阅读寻找中心句的技巧,对学生考试技巧的提升有一定的帮助。
而且此题符合高考中信息匹配题型,从中训练他们快速寻找信息的能力。
Step4 Carefully readingRead the text again and find the details of each paragraphs.Para.1 DefinitionWhat is cloning?Para.2 use and breakthrough (Discuss in your group and give the answer)1.How many major uses do cloning have?2. Why is it easier to make commercial plant clones than animal clones?3. When was the cloning of Dolly the sheep born? Why did the scientists succeed in cloning it?4. Describe how to clone following the picture.Para3 problemWhat is the problem of Dolly?Para4 impact and reactionWe can infer from the last three paragraphs that ___.A.The normal development of Dolly had no effect on the cloning of other species.B. Dolly’s serious disease and final death disturbed the whole world.C. Dolly successfully cloned a new lamb with the help of cloning scientists.D. There were arguments about animals about animal cloning and concerns about the future of cloning.设计意图:第一,在泛读过几次课文之后学生对课文有了一定的了解,此时的细读正是让学生更好的检查自己掌握情况。
第二,单独做题之后是讨论,通过合作学习共同得出较为正确的答案,这正是此节课一个教学方法的体现。
Step5 DiscussionIs cloning beneficial or harmful to us?Advantages VS. Disadvantages小组活动,利用课文所学内容和自己对克隆的理解展开充分想象。
辩论环节是本节课话题的一个延伸和升华,能唤起学生对生活的关注,知道克隆的意义和克隆技术可能的利与弊,激发学生热爱科学的热情,这也正是本节课的情感目标。
此外,给予学生充分时间开口讲英语也实现了英语教学“听说读写”中“说”的要求。
如果学生遇到困难,可以参考细读中问题的信息,这样就可以避免无话可说的尴尬,对于他们树立信心有很大的作用。
Step6 AssignmentRetell the textCloning is ___________________ of another animal or plant. Cloning has _________. One is for __________;the other is _________ Although _________ is complicated Dolly the sheep is ________________.Before long, she _____________and only ___________________. However, her appearance _____________ and arguments .Some countries became ______________________. Therefore, ___________ is forbidden. Nobody knows ______.这个作业不难,第一,以高考中的填空的形式作为练习题让学生更加接近高考,可以更好得为高考服务。
第二,以总结课文的形式展示既可以让学生了解文章主要内容,也可以帮助学生学会总结文章。
这也是本节课的一个教学评价。
六、教学评价设计学生学习的评价方案备注ABC三个等级分别赋予分值5、4、3七、板书设计八、教学反思Unit2 Cloning是一篇介绍克隆技术的说明文,专业性强,文中生词多,学生理解难度大。
根据这些特点,本单元我以训练阅读技巧之略读和扫读为主,并鼓励学生多思考,多发言,增强他们的信心。
在教Reading部分,在课堂教学中以复习生词进入课文,然后再以大量图片导入新课。
授课中始终围绕读,重在培养学生阅读技能,以scanning,skimming和careful reading等循序渐进的阅读方法,结合任务教学法和合作学习,让学生带着任务学习,促使学生积极配合,收到了良好的学习效果。
本节课充分体现了对语言学习的要求,从最开始的读,到完成任务后在黑板上写答案,到讨论时自由发挥,听说读写各个方面都涉及到了,学生完成情况也相当地好,设计的任务基本都跟高考相接轨,任务的实用性和环环相扣充分体现了它的现实意义,学生从而也会投入更多的激情学习。
