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。
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:
Step 2 Pre-listeningAfter students finish their discussion, I will show a picture of Newton and ask them: Who is him? What is he famous for? Could you find out some words to describe him? Maybe students will answer that he is genius for his finding of theGravitation, making a great contribution to the progress of human being. At that time I will show another two pictures of Einstein and Hawking, letting students guess who they are and write down their idea about the Gravitation. For I have arranged them to search more information about the gravity before this class, Students have beenfamiliar with the topic and will not be afraid about this abstract conception, which is helpful for their listening.Step 3 While-listeningIn this step, students will be required to listen the material for three times. The first and listening is extensive listening and the second and third listening is intensive listening. In the first time, They are required to listen a material including Part 1 and Part 2 and choose the best summary of the listening text. After they choose the right answer, They also need work in group to explain what is wrong with the others. Then I will make a conclusion that we should pay attention to the first paragraph and last paragraph and some keys to get the main idea. By doing this, their capacity of generalization will have a great improvement.Before the second listening, I will ask students to scan the blank on the power point quickly and ask them to note down some key words .Then ask them to listen to the Part 1again and fill the first column of the chart. Maybe some students just show the ideas of these three scientists an still can’t catch their development of gravity. Therefore, I will ask them to listen to Part 2 again and fill in the rest. After finish the listening, I will give them ten minutes to discuss with their partner. I will also guidethem to improve their answers when they discuss with others.
When it comes to the students’ studying methods, I'd like to introduce my Ss first. The Ss have a good command of basic language points. They’re interested in learning English, and they take an active part in English class, so they will have fun in autonomous, cooperative and inquiry learning. I will just serve as a guide, showing them the way to explore how to make more progress in their English learning.Now it’s time for the most important stage of this lesson. My teaching procedures are arranged as follows:Step1.Leading-in (3 minute)Play a video of a wide variety of wildlife to introduce my topic. Step2. Speaking (12 minutes)We will use our textbook Page25. Let the Ss fast read the short paragraph to warm up. Ask them to talk about the report on some endangered wildlife in China with the dialogue patterns on the screen. Lastly, I will invite some groups to demonstrate their dialogues about saving wildlife in China.Step3.English play (3 minutes)Watch another video in praise of their excellent performance just now. It’s about Jack Chen’s(成龙)and Yang Ziqiong’s wildlife protection.Step4. Listening (twice 13 minutes)This time, I’ll ask the Ss to fill in the blanks of the monologue of the 2 movie stars above. Step5.Discussion (3 minutes)Which would you like to choose to wear, clothes made of cotton, artificial leather or animal skins? Why ?Step6. Summary (3 minutes)1. If there were no wildlife, there wouldn’t exist human beings. If the buying stops, the killing can, too.2. Animals are our friends. To love animals is to love ourselves. Stop hunting, killing and destroying wildlife.3. Let’s live in harmony with all the living things in the world. Step7. Music appreciation (3 minutes)Let the Ss appreciate the song Earth Song by Michael Jackson. Last but not the least, I will show you my blackboard design.
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.
在接下来的细读环节,我套用了高考对阅读理解的考查方式设置了5个问题,分别为三个推理判断题,一个细节题和一个主旨大意题。学生需要对文章的内容进行分析、归纳、推理、猜测等高级思维活动才能做出正确的回答。【设计意图】这一过程是对学生进行细读的训练,培养学生获取特定信息和挖掘文章深层次信息的能力。第三环节:Intensive-reading (精读) 15′第三个环节精读,既是最重要的环节,也是突破本课重难点的关键。首先,让学生思考剧本中人物看到百万英镑前后的态度发生了怎样的变化。其次,让学生仔细阅读文章,找出可以表现人物态度变化的具体的语言和动作。最后,让学生总结人物的态度发生变化的根本原因是什么,从而引出Money Talks, 供学生思考。【设计意图】通过一系列的活动培养学生学习从人物的语言和动作探究人物的心理,使学生进一步体会戏剧语言的魅力,从而对文章背后所反映的社会问题进行思考,也为下一步的讨论环节做好铺垫。
In this class, I have 3 teaching aims, that is, knowledge aims, ability aims and emotion aims.1) Knowledge-Teach students new words and expressions, such as temporary, bleed,sprain choke, first aid, fall ill and so on.-Enable students to have a better understanding for some basic knowledge of first aid.2) Ability-Train students’ speaking, reading and writing abilities by different teaching activities, such as skimming, comprehending, team work, role play, retelling and writing.-Develop students’ reading strategy on how to move general idea to specific information.3) Emotion-Promote students’ awareness of giving first aid.- Cultivate students’ creativities.Then let’s come to my teaching methods and activities.III. Teaching methods and activities:To achieve different teaching aims, various kinds of teaching methods and activities will be adopted throughout this period, such as TBL (task-based learning), skimming, team work, brainstorm and others, which can offer students opportunities to fulfill tasks in which they can use language to achieve a specific outcome.IV. Teaching aids:Computer and blackboardV. Teaching important points:1) Make students have a clear mind for the structure of the text.2) Help students understand the theme of the text.VI. Teaching difficulties:1) So many new words may affect students’ understanding.2) How to get students to know about the functions of the skin and thecauses, characteristics and treatments for different degree burns,and the knowledge about giving first aid. VII. Blackboard design:

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。
(二)分析课文,理清思路第1、2段为第一部分,主要是叙事、写景,先叙述集会的时间、地点,然后渲染出兰亭优美的自然环境。在这里足以“游目骋怀”“极视听之娱”,可以自由地观察、思考,满足人们目视耳闻的需求。这里正是与会“畅叙幽情”、尽兴尽欢的绝好处所。这些描写都富有诗情画意,作者的情感是轻松愉快的。第3、4段为第二部分,主要是抒情、议论,作者由美景妙时引发出乐与忧、生与死的感慨。他认为人生的快乐是有极限的,待快乐得到满足时,就会感觉兴味索然。往事转眼间便成为历史,人到了生命的尽头就会死亡。作者由“一死生为虚诞,齐彭殇为妄作”的认识,产生了一种珍惜时间、眷恋生活、热爱文明的思考。虽然文中的寿夭、生死不能自由决定,从而有些伤感,但作者仍然认识到盛衰、生死是必然的。人生无常,时不我待,故著文留传后世,以承袭前人,启示来者。
一、说教材《短歌行》是普通高中课程标准实验教科书必修(二)第二单元的一篇略读课文,本单元安排的是先秦到南北朝时期的诗歌。《短歌行》是著名政治家、军事家、文学家曹操的作品。诗中抓住“忧”字来写诗人为什么“忧”,如何解“忧”,从而表达希望能够招揽人才、完成统一天下的雄心壮志。所以本单元安排《短歌行》一诗,对学生全面了解曹操,感受曹操在短暂的人生中竭力创造伟业的气概。二、说学生我这一课的教学对象是高一学生。他们进入高中学习的时间只有三个多月,现在已经完成了必修(一)的学习。学习了现代诗歌单元,有了一定的诗歌学习基础,初步掌握了读诗的基本方法,但是还未能形成成熟的稳定的学习方式。同时,本单元学习是高中第一次接触古代诗歌,诗歌语言上的障碍和时间上的跨度对他们来说都是学习上的困难。因此教师要引导学生自主学习,合作学习,为他们设置新的学习情境,提供合作探究的机会。
【教学目标】我设置的本课的教学目标有三个:1、知识与技能(1)了解曹雪芹及《红楼梦》(2)学习通过一个人物的行踪、所见所闻,介绍典型环境,认识封建贵族阶级豪奢极耻的生活以及森严的等级、礼仪制度(3)分析小说人物出场的描写艺术,培养学生分析小说人物形象的能力。(4)一叶落而知秋”,通过对“林黛玉进贾府”这一故事情节的把握是否能引发对《红楼梦》的认知兴趣,并找到一个突破口,有针对性地进行自主探究,进而进行个性化解读。(5)整体认知小说,认识小说悲剧的必然性和思想价值.2、过程与方法(1)用直观演示和归纳探究法分析文章要点。(2)用讨论探究法体验作者对文中人物的情感态度。3、情感态度价值观(1)正确理解《红楼梦》的思想内涵,培养学生热爱祖国传统文化的思想感情。(2)认识封建大家族的腐朽没落,理解贾宝玉追求个性自由反封建的精神。
一、导入新课人类社会越来越现代化,新科学技术日新月异,令人目不暇接,称之到了“知识爆炸”的时代也毫不为过。由此而来的是生活的快节奏,学习和工作的竞争也越来越激烈。这种竞争一直波及到了儿童,加之中国几千年来形成的望子成龙的传统观念,使作父母的把一切希望都寄托在孩子身上,实现自己未能实现的理想。祖孙三代4、2、1的局面,使12只眼睛都盯在了孩子身上,真是走路怕摔着,吃饭怕噎着,干活怕累着,要星星不敢摘月亮,要吃什么跑遍全城也要买来。这种过分保护、溺爱及过早地灌输知识会得到什么结果呢?乐观者说孩子越来越聪明,越来越早熟,将来能更好适应现代化的要求;悲观者则认为豆芽菜式的孩子将来经不起风浪,小皇帝太多了很难凝聚成统一力量,将来谁去当兵,谁去干那些艰苦创业性工作……。对孩子本身来说,是幸福还是……在此不想多发议论,还是让我们来看看动物世界的孩子们吧,也许会得到某种启迪。
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。
《劝学》是普通高中课程标准试验教科书语文必修三第三单元的重点篇目,该文集中反映著名思想家荀子在学习问题上的观点和精彩斐然的论证艺术。该单元所选课文都是古代的议论性散文。通过本单元的学习在于让学生感受我国传统文化的精神,掌握基础的文言语法知识,学习如何清晰有力的表达自己的思想和见解。本文安排在单元的第一篇,如何指导学生学好这篇课文,是实现“授之以渔”,树立学生学好文言文的信心,掌握文言学习方法的关键。根据新课标倡导从“知识与能力”、“过程与方法”、“情感态度与价值观”三方面出发设计课程目标的要求和高一的学生对于文言文的知识还在积累的阶段,应该注重基础知识的积累和一定量的诵读的实际情况。我拟确定以下教学目标:1,了解荀子论述学习的思想,明确学习要靠积累、坚持不懈、专心致志的道理。2,掌握积累文言实词、虚词,活用、古今异议等现象和固定句式。
(1)“问君西游何时还……使人听此凋朱颜。”诗题下未注明送何人入蜀,所以这里的“问君”无妨假定实有其人,可以读得亲切一些。将行而问“何时还”,已有不可行之意,重音要落在“不可攀”三字上,当用劝说的语气读。以下四句借鸟声渲染旅途中悲凉凄清的氛围,读时要放低声调,有干里孤身之感,至“愁空山”徐徐而上。然后用感喟的语调读主旨句,至“凋朱颜”略作一顿,以示意犹未尽。(2)“连峰去天不盈尺……胡为乎来哉!”仍是说不可行,但内容加深了一层,因为说的是蜀道的险恶。前四句不是纯客观的描写,读时须设想这是旅游者攀援于“连峰”“绝壁”之上置身于“飞湍瀑流”之间,要使听者感到惊心动魄。读后可作稍长停顿,再用“其险也如此”缓缓收住。末句是诗人借用蜀人的口气,对历险而来的游者深表叹息——“胡为乎来哉”不是询问,当用降调读,暗含“何苦而来”之意。
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。
