四、说教学程序(一).温故知新、导入新课复习提问:基因突变导致生物变异的原因是什么?回答:基因突变是基因结构发生改变,从而使遗传信息改变,使蛋白质结构改变、生物性状改变,即生物发生了变异。那么,基因是什么?它和染色体又有何关系?回答:基因是有遗传效应的DNA片断,染色体是DNA的载体,基因在染色体上呈线形排列。引出新知:对于一个生物体来说,正常情况下,其染色体的结构和数量都是稳定的。但在自然条件或人为因素的影响下,染色体的结构和数量均会发生改变,从而导致生物性状的改变,这就属于染色体变异。(二).把握重点、突破难点重点的把握:1、染色体结构的变异播放影片:猫叫综合征幼儿。让学生观察: 患儿哭声轻、音调高,很像猫叫。教师补充: 患儿的征状---两眼较低、耳位低下,存在着严重的智力障碍。阐述病因---染色体片段缺失
一. 教材分析1. 本单元的中心话题是“计算机(Computers)”,内容涉及计算机的发展历史,计算机的应用等。本节课是该单元的第一课时,我将Warming up, Pre-reading and Comprehending这四部分整合为一节精读课。其中。Reading部分是题为WHO AM I?的文章,以第一人称的拟人手法介绍了计算机发长演变的历史和计算机在各个领域的应用,其主旨是表达计算机的发展变化之快以及在生活中用途之广。而Warming up部分以图片的形式展现了计算机的发展历程;Pre-reading中的问题和排序分别是为了预测语篇的内容和测试学生对计算机历史了解的情况;Comprehending则通过各项练习训练学生的阅读技能,从而加深对文章的理解。可见这几部分是一个有机的整体。2. 教学目标:1) 语言目标:重点词汇及短语:abacus, calculate, calculator, PC, laptop, PDA, robot, analytical, technological, universal, mathematical, artificial, intelligent, network, explore, in common, as a result.重点句子:a. My real father was Alan Turing, who in 1963 wrote a book to describe how computers could be made to work, and build a “universal machine” to solve any mathematical problem.
Ⅲ. Analysis of the teaching material:The topic of this unit is cultural relics. Students are quite interested in topics about different cultures around the world. This is the second period of the whole unit. As a reading class, the passage mainly talks about the history of the amber room (how it was made, sent as a gift, lost and rebuilt).According to the new national curriculum, when teaching reading, much emphasis should be put on training the students’ reading skills.Ⅳ. Teaching objectives1. Language objectives:1) Students are required to master the key words and phrases occurred in the passage (e.g. amazing, decorate, belong, in return, less than etc.)2) Students are required to learn the attributive clause and acquire the sentence pattern.2. 1) Students are required to describe a certain thing by using the new sentence patterns.2) Students are required to master two kinds of reading skills—skimming and scanning, and learn to use them in their daily reading.3. 1) Students are required to know the history of the amber room.2) Students are required to appreciate cultural relics and understand the importance of protecting them.Ⅴ. Teaching important and difficult points1) the new words, phrases, and sentence pattern in the course of reading.2) Teaching difficult point: Help the students master two kinds of reading skills—skimmingand scanning and learn to apply them in daily use.Ⅵ. Teaching methods:Task-based method & Top-down model Ⅶ. Teaching aids: PPT, pictures, blackboard Ⅷ. Teaching procedure:
Then I would ask them to think of a funny English or Chinese and tell it to partners. While telling stories, they can use expressions and some acting to help make the story funny. 5 minutes would be given to do this.Those stories they told there will be the material for their writing. Soletting them tell it at first is helpful. And they can make a difference between telling a funny story and writing it down. Generally speaking, it is difficult forstudents to write well because they don’t know what to write and how to write. Asking them to tell their own stories at first can help them come up with what to write.After their telling, I would invite someone to share his/her story with all of us and I would write it down on the blackboard.This example story would be used as a sample to illustrate the format of funny story. Different from a story from teacher or textbook, a story from students can obviously become a interesting material to draw students’ attention.Then I would ask the whole class to put this story into several parts. It might be a little bit difficult for them. So I would ask them to find out whether all the sentences are necessary. After delete some sentences, there are 6 sentences left behind. Then they can easily put them into three parts. After interaction with students, I would teach them the right terms for each part and conclude the format of funny story.This step is the key and difficult point in my lesson. So I mainly usetask-based teaching method in this part and the task for students was divided into several stages. With the separated difficult level, students can find there are usually three parts in writing. They can also learn to write without the unnecessary parts in the process of analyzing. And then I wouldn’t rush to tell them the right terms to them directly. Instead, I would ask them to name them by their own. A confused mind is better for acquiring knowledge.While-writing:Then I would give students 7 minutes to write down this story, without other requirements.With all the preparations in pre-writing, students’ difficulties were cleared. So it would be much easier for them to write down the story within 7 minutes. There are no other requirements because students’ first writing is actually a drafting. It would be revise and edit several times later. Writing, as a skill
Good afternoon, teachers, It’s my great pleasure to be here sharing my lesson with you.The content of my lesson is Senior English Book 3 Unit 5 Canada —— “The true North”.I’ll be ready to begin this lesson from five parts.

Language learning needs a context, which can help the learners to understand the language and then can product comprehensible output, so computer has the advantages to make the materials attractive.Part 3 Learning MethodsTask-based, self-dependent and cooperative learningPart 4 Teaching ProcedureStep One Lead-in“Interest is the best teacher.” Therefore, at the very beginning of the class, I should spark the students’ mind to focus on the centre topic “the band”. I’ll show some pictures of food to attract their attention and then bring some questions.Question:What kind of food they like?What should go into a good meal?The answers must relate to the diet. After this, the students will be eager to know something about a balance diet and this is the very time to naturally lead the class into Step 2Step 2 Reading for information: skimming and scanning In this step, I use Task-based Language Teaching method, which can give students a clear and specific purpose while skimming and scanning the context.Task 1 General ideaThe students will be asked to just glance at the title and the pictures of the passage, and then guess what they will read in the text. And they’ll be divided into groups of four to have a discussion.The purpose is to inspire the students to read actively, not passively. In addition, the task is to develop the students’ reading skill by making prediction and to encourage the students to express their thoughts in English and cooperate with each other.Task 2 Main idea of each paragraphCooperative learning can raise the students’ interest and create an atmosphere of achievement. Based on this theory, I divide the whole class into 4 groups to skim the whole text and get the main idea of each paragraph.

今天我们来介绍一下必修五第四单元的授课方式。这个单元的题目是Making the news。应该是学生比较感兴趣的话题,学生往往对新闻工作充满好奇,所以我们可以利用这个机会多设计一些师生互动和学生互动,来激发起学习的积极性,提高学习效率。同时我们可以利用这个单元不仅帮助学生掌握语言知识,培养语言能力,同时让其了解新闻工作的重要性,培养起社会智能感。这个单元分为六个课时,它的教学目标是这样的:语言目标是掌握词汇表中的常用单词和短语,掌握倒装句的一些基本用法。 技能目标是能初步掌握约会的基本句型并在真实的场景下正确运用。新闻报道类文章的写作技能。采访的基本规范和沟通技能。情感目标是对新闻报道的客观性和真实性有更好的理解。对新闻记者的职业有更深入的了解,并能体会其工作的重要性。下面我们来介绍一下第一课时的授课方式,第一课的教学目标是这样的第一课时的教学目标语言目标:单词:Occupation, journalist, editor, photographer, curious, personality, enthusiasm
一、说教材1.教材分析《涉江采芙蓉》是新人教版必修二第二单元《古诗三首》中的一首。《古诗十九首》在中国古代诗歌的艺术手法上起着承前启后的作用,在高中语文古诗教学中也起着承前启后的作用。这首古体诗不论是艺术上,还是在思想上都已经达到了十分纯熟的境界。因此,它十分重要。2.说学情这首诗歌在内容上难度不大,可以做多角度解读。新课程标准鼓励学生作个性化解读,我们可以引导学生就此作些探讨。学生通过小学、初中的系统学习和本册古诗部分的集中学习,有了一定的古诗鉴赏能力,对源远流长的中华文化也有了一些积淀,兴趣渐浓,这是进一步引导学生热爱古代诗歌、学习古代诗歌的一个前提。3.教学目标依据学生特点,教材特色以及新课标的要求,制定教学目标如下:(用多媒体展示)1、了解关于《古诗十九首》的文学常识;2、感受诗歌的思想内涵;3、运用想象描摹诗歌的艺术画面。
学法指导:高一学生对文言文阅读已具备了一些基础知识和积累,但对如何学习文言文,还是一个新课题,因此教师应引导学生掌握学习方法,运用已有的知识框架同化新信息,建立新的智能,逐步走向独立学习的境界。一、引导学生利用课文注释,使用工具书自己翻译,必要时教师进行点拨、解难,培养自学能力。二、告诉学生翻译文言文要遵循的原则。三、调动学生思考、讨论、交流的积极性,教师适时点拨,培养学生发现问题、解决问题的能力。四、提示学生反复诵读课文,体会文章所阐述的道理。五、鼓励学生及时归纳学习文言文的方法,注意积累文言文知识。教学程序:教学本课可安排2课时。第一课时:1、导入新课:首先给学生介绍毛泽东的七绝诗《为李进同志题所摄庐山仙人洞照》:“暮色苍茫看劲松,乱云飞渡仍从容。天生一个仙人洞,无限风光在险峰。”学生通过诵读领会了“无限风光在险峰”一句的含义。随后因势利导,引出课题,指出今天我们要学习的王安石的《游褒禅山记》,就含有类似的深邃哲理。
我以以《登高》为例,引导学生进行意象分析,感悟意境美。古人云“立象以尽意”“古诗之妙,专求意象”意象是诗人情感的载体,是诗歌的灵魂。引导学生张开联想和想象的翅膀去感受,去体验是意象,诗歌鉴赏的关键。科林伍德说“真正艺术的作品,不是看见的,也不是听到的,而是想象中的某种东西。”诗人通过想象创造出诗的形象,我们读者通过想象丰富地再现诗人创造的形象。而感受体验则是以全部身心投入作品,心灵与心灵相沟通,感情与感情相交流,对诗人的想象活动进行再经历和再体验。因此,在引导意象解读中,我先让学生点击这一个,就是通过抓修饰词、依据感情基调、展开想象具体分析本诗中每个意象的情感意蕴和审美意蕴,使学生明白意象在每首诗中的独特性。
本文篇幅较长,并且有一字句不易理解,因而对高一学生来说完全读懂内容有一些困难。这样的话,老师就要做好引导工作,把一些难点,或是出现词类活用比较多,局势比较特殊的句子,老师可以先给学生画出来,存疑,或是与同学们一起讨论解决。对那些不易懂的字词就引导学生联系上下文提供的语境、前后涉及的情节加以推测、判断,以培养学生依据文脉推断词义的好方法。要求学生点出重点实词、框出通假字,主要是为帮助学生积累和掌握一些文言文中常见的一词多义、异读现象、古今异义和通假现象的词语,并进一步得出规律,指导今后的文言文学习。词类活用和特殊句式在文言文翻译中难度较大,也是本文教学的两大难点。要求学生标出有活用现象的字和划出句式特殊的句子,是基于两点考虑:1、积累一定数量的第一手例句;2、引导学生加以分类,找出每类的相同特征,并抽取出来形成规律性的东西,从而上升到理性认识,使学生能由学会一个到会学多个。翻译过程中注重指导学生养成用符号法表示重点字句的好习惯,如点、框、圈、划线等符号应约定一致,便于突出翻译中的重点、难点及复习。我的提示着重归纳了实词“制”“亡”“遗”“利”等,名词活用、形容词活用、使动用法,被动句、状语后置句。
说教材A.教材简析《琵琶行(并序)》是人教版《普通高中课程标准实验教科书语文》必修3第二单元的一篇讲读课文。本单元学习的是唐代诗歌,共七首诗。《琵琶行(并序)》是唐代著名现实主义诗人白居易写的一首歌行体长篇叙事诗,是我国古代叙事诗和音乐诗中的“千古绝喝”。诗歌主题鲜明、人物形象生动,抒情真切细腻,具有深刻的思想内容和卓越的艺术技巧。B.教学目标《全日制普通高中高级中学语文教学大纲》明确要求我们:在阅读教学过程中要引导学生“感受文学形象,品味文学作品的语言和艺术技巧,初步鉴赏文学作品”。而本单元的教学要求是培养学生诗歌鉴赏的能力。根据教学大纲和单元教学要求,结合本课特点,我制定本课的教学目标是:1.知识目标:了解文学常识;积累重点文言实词;品味主旨句“同是天涯沦落人,相逢何必曾相识”的内涵;感知作者把音乐描写与听者、演奏者的感情融为一体的写作特点。
(有的恒星旋转平稳均衡,有些恒星是因快速旋转而变了形。作者以拟人的手法,生动形象地描述,仿佛向我们展示了不同恒星的性情:有的稳重沉静,有的急切躁动。读来生动有趣,妙趣横生。)(3)我们探索宇宙的时候,既要勇于怀疑,又要富于想象。想象经常能够把我们带领到崭新的世界,没有想象,我们就处处碰壁。怀疑可以使我们摆脱幻想,还可以检验我们的推测。(对于未知领域的探索是需要怀疑和想象的,想象是科学的翅膀,敢于想象,并不断地探索验证,所谓“大胆假设,小心求证”怀疑否定旧知,产生新知。作者以简洁的语言阐述了想象和怀疑看似矛盾的两者在宇宙探索中的相辅相成,和谐统一。作者不囿于介绍宇宙知识,还发表自己的见解。)(4)我认为宇宙里很可能到处都充满着生命,只是我们人类尚未发现而已。我们的探索才刚刚开始。
各位评委老师,大家好。我说课的题目是《祝福》。一、说教材(一)教材所处的位置和地位高中语文新课程教材必修五本书,共有2个单元中外小说单元。一个必修3的第一单元,一个是必修5的第一单元,共六篇文章。(《林黛玉进贾府》《祝福》《老人与海》《林教头风雪山神庙》《装在套子里的人》《边城》)《祝福》是属于前者。小说是拥有众多读者的一种文体,它可以多方面刻画人物性格,描摹人物心理,完整地表现人物之间的冲突,还可以具体生动地再现人物生活的环境,因此在反映复杂的社会生活方面具有独特优势。所以学习小说这种文学样式,也是有助于学生学会鉴赏小说的基本方法,为将来的小说阅读打下基础。鲁迅的《祝福》是中国现代小说的精品,当中的人物祥林嫂也是鲁迅小说中与阿Q、孔乙己三个最为出名的人物之一。研读好这篇文章,对将来小说的阅读,小说中人物的理解,甚至小说的写作都有深广意义。
教学内容与分析本课内容是大众传媒的变迁,首先解题,了解什么是大众传媒。大众传媒就是传播大众信息的媒体,进入近代社会以来,人与人之间的联系变得越来越密切,社会化程度大大加深,需要有一种大众化、传播速度快、传播范围广的媒介作为人与人之间进行信息沟通的渠道,人类社会的传媒手段应运而生,可由学生总结出有哪些主要的方式。报刊、影视、广播,这三种大众传播媒体的依次出现,给人们的生活方式带来了巨大的变化,被称为三大媒介。由于互联网同报纸、广播和电视三大媒介一样,具有传播信息的功能,所以被称为“第四媒介”,即“网络媒介”。通过本节课的学习使学生了解中国近代社会生活的变化,体会历史和时代发展的必然性,能够站在发展的角度、用历史的眼光思考问题。
教材地位本课具有承上启下的作用,前承文艺复兴,后启资产阶级革命时代的到来,启蒙运动为资本主义社会构建了一套政治蓝图,具有前瞻性,是近代第二次思想解放运动。因此,本节内容在整个教材中有着很重要的地位。教学目标1、知识目标:(1)帮助学生了解启蒙运动的性质、内容和主要启蒙 思想家及其主张。(2)理解启蒙运动兴起的背景、影响。2、能力目标:(1)在讨论和探究过程中训练学生的科学思维方法和自主学习的能力和掌握解题的方法。(2)通过指导学生阅读启蒙思想家的言论资料,培养学生对历史资料的理解和归纳能力。3、情感价值目标:(1)培养人文意识,强化法治观念。(2)培养学生的团结协作精神和竞争意识。教学重点、难点(1)教学重点:启蒙思想家的主张及启蒙运动的影响。
陆王心学与程朱理学相比有何异同?生 不同点:在理的内涵上不同,程朱理学认为“理”是贯通于宇宙、人伦的客观存在,是一种普遍的规律准则;陆王心学认为心即理,是“良知”,认为人心便是世界万物的本原。方法上也有不同:前者向外追究,“格物致知”;后者向内探求,“发明本心”以求理,克服私欲、回复良知。生 相同点:都提出了一个宇宙、社会、人生遵循的“理”。师 对。程朱理学是客观唯心主义,阳明心学是主观唯心主义。这两者的分歧是理学范围内的分歧,其基本思想是一致的。师 宋明理学与汉唐以前的儒学比较,最大的特点在于批判地吸收了佛教哲学的思辨结构和道教的宇宙生成论,将儒家的伦理学说概括升华为哲学基本问题。其实质是把佛、道“养性”“修身”引向儒家的“齐家”“治国”“平天下”,对儒家的纲常道德给予哲学论证,使之神圣化、绝对化、普遍化,以便深入人心,做到人人遵而行之。
三、孟德尔遗传规律的现代解释①分离定律:在杂合体的细胞中,位于一对同源染色体上的等位基因,具有一定的独立性;在减数分裂形成配子的过程中,等位基因随同源染色体的分开而分离,独立地随配子遗传给后代。②自由组合定律:位于非同源染色体上的非等位基因的分离或组合是互不干扰的;在减数分裂过程中,同源染色体的等位基因彼此分离的同时,非同源染色体上的非等位基因自由组合。总结:再次强调孟德尔遗传定律的现代解释课堂练习:书本31页6、教学反思:本节课设置了一系列问题情境,层层设问,在学生答问、质疑、讨论过程中让学生建构新概念和新的知识体系,并通过教师及时掌握反馈信息,适时点拨、调节,让学生在推理判断中培养良好的思维习惯和对知识的迁移能力,而且通过留出一定的时间让学生提问,体现了以学生为主体的思想。
