四、說(shuō)教學(xué)程序（一）.溫故知新、導(dǎo)入新課復(fù)習(xí)提問:基因突變導(dǎo)致生物變異的原因是什么?回答:基因突變是基因結(jié)構(gòu)發(fā)生改變，從而使遺傳信息改變，使蛋白質(zhì)結(jié)構(gòu)改變、生物性狀改變，即生物發(fā)生了變異。那么，基因是什么?它和染色體又有何關(guān)系?回答:基因是有遺傳效應(yīng)的DNA片斷，染色體是DNA的載體，基因在染色體上呈線形排列。引出新知:對(duì)于一個(gè)生物體來(lái)說(shuō)，正常情況下，其染色體的結(jié)構(gòu)和數(shù)量都是穩(wěn)定的。但在自然條件或人為因素的影響下，染色體的結(jié)構(gòu)和數(shù)量均會(huì)發(fā)生改變，從而導(dǎo)致生物性狀的改變，這就屬于染色體變異。（二）.把握重點(diǎn)、突破難點(diǎn)重點(diǎn)的把握：1、染色體結(jié)構(gòu)的變異播放影片:貓叫綜合征幼兒。讓學(xué)生觀察: 患兒哭聲輕、音調(diào)高，很像貓叫。教師補(bǔ)充: 患兒的征狀---兩眼較低、耳位低下，存在著嚴(yán)重的智力障礙。闡述病因---染色體片段缺失

人教版高中語(yǔ)文必修1《雨巷》說(shuō)課稿3篇
一.教材理解教材地位與作用：本單元“閱讀與鑒賞”部分，本單元要求學(xué)生能在了解詩(shī)歌創(chuàng)作的時(shí)代背景的情況下通過反復(fù)誦讀詩(shī)歌，把握其中豐富的意象，領(lǐng)悟詩(shī)歌獨(dú)特的意境和詩(shī)人所要表達(dá)的情感。《雨巷》是現(xiàn)代派大師戴望舒的成名作和前期的代表作,他曾因此而贏得了“雨巷詩(shī)人”的雅號(hào)。本單元以《雨巷》為例子給學(xué)生展示了象征主義詩(shī)歌的特點(diǎn)，《雨巷》運(yùn)用了象征性的抒情手法。詩(shī)中那狹窄陰沉的雨巷，在雨巷中徘徊的獨(dú)行者，以及那個(gè)像丁香一樣結(jié)著愁怨的姑娘，都是象征性的意象。這些意象又共同構(gòu)成了一種象征性的意境，含蓄地暗示出作者即迷惘感傷又有期待的情懷，并給人一種朦朧而又幽深的美感。富于音樂性是《雨巷》的另一個(gè)突出的藝術(shù)特色。詩(shī)中運(yùn)用了復(fù)沓、疊句、重唱等手法，造成了回環(huán)往復(fù)的旋律和宛轉(zhuǎn)悅耳的樂感。因此我把本課的教學(xué)重點(diǎn)和難點(diǎn)確定為：教學(xué)重點(diǎn)：通過反復(fù)誦讀，領(lǐng)略詩(shī)歌的音樂美以及分析其成因教學(xué)難點(diǎn)：分析意象以及其象征意義初步掌握鑒賞詩(shī)歌的方法

人教版高中英語(yǔ)必修4A taste of English Humor說(shuō)課稿3篇
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

基于以上分析，為使本堂課圍繞重點(diǎn)、突破難點(diǎn)，同時(shí)讓學(xué)生在課堂教學(xué)中能力得到提高，我設(shè)計(jì)如下教學(xué)過程。（一）創(chuàng)設(shè)情景認(rèn)識(shí)形變由同學(xué)們已有的形變知識(shí)入手，引入新課。教師演示：①?gòu)椈傻膲嚎s形變；②彈簧的拉伸形變③視頻播放：竹竿形變、鋼絲的扭轉(zhuǎn)形變。得出形變的概念及各類形變。[設(shè)計(jì)意圖：我從生活情景中引入新課，是為了激發(fā)學(xué)生的好奇心，為學(xué)生學(xué)習(xí)重點(diǎn)和難點(diǎn)內(nèi)容作鋪墊。]設(shè)問：摩天大樓在風(fēng)的吹拂下會(huì)不會(huì)擺動(dòng)，發(fā)生形變嗎？演示微小形變放大實(shí)驗(yàn)：由于這種形變不容易觀察，會(huì)使學(xué)生產(chǎn)生疑問：到底有沒有發(fā)生形變？解決的辦法是微小形變的演示實(shí)驗(yàn)。為什么光點(diǎn)會(huì)往下移？讓學(xué)生帶著問題思考后得出結(jié)論：是由于桌面發(fā)生了形變，但是形變不明顯。為后面解決壓力和支持力都是彈力做好鋪墊。[設(shè)計(jì)意圖：使學(xué)生知道“放大”是一種科學(xué)探究的方法。]

一、教材分析1、教學(xué)對(duì)象分析《再別康橋》的教學(xué)對(duì)象是高一學(xué)生，高一學(xué)生往往對(duì)那種純粹的、原始的、本真的情感體會(huì)較為膚淺，《再別康橋》是新月派詩(shī)人徐志摩的傳世之作，有極高美學(xué)價(jià)值，它所抒發(fā)的離愁別緒是人類共同的情感經(jīng)歷，通過誦讀容易將學(xué)生帶人詩(shī)境，喚醒他們沉寂的真情，從而引起強(qiáng)烈的共鳴。 2、教材地位及作用 高中語(yǔ)文第一冊(cè)第一單元為詩(shī)歌單元，本單元收錄了中國(guó)現(xiàn)當(dāng)代的一些優(yōu)秀詩(shī)篇?！对賱e康橋》安排在本單元的第二課，屬于必讀課。雖然本詩(shī)向來(lái)眾說(shuō)紛紜，但其藝術(shù)之美人所共知，培養(yǎng)學(xué)生高尚的審美情趣和良好的審美創(chuàng)造力是語(yǔ)文學(xué)科的任務(wù)，因此，從語(yǔ)言賞析入手，從情感體驗(yàn)切入，就可以讓學(xué)生通過學(xué)習(xí)本課體會(huì)現(xiàn)代詩(shī)歌的特點(diǎn)，多方面感受體悟詩(shī)歌的情感，受到美的熏陶。
人教版高中語(yǔ)文必修1《包身工》說(shuō)課稿2篇
（一）解題：包身工──舊社會(huì)一種變相的販賣奴隸的形式。被販賣的多是女孩子由承辦人送到工廠做工，無(wú)人身自由，所得工資全部歸承辦人所有，在這種形式下做工的人也稱包身工。包身工是指二三十年代（時(shí)間），在上海東洋紗廠里（地點(diǎn)），為外國(guó)人工作的女工（工作性質(zhì)）。因?yàn)檫@些女工在進(jìn)廠時(shí)已經(jīng)簽訂了賣身契，失去了人身的自由權(quán)，所以被稱為“包身工”。標(biāo)題中的“包身”二字，突出了帝國(guó)主義、封建勢(shì)力對(duì)中國(guó)女童工的殘酷剝削的罪行，控訴了他們的野蠻殘暴的統(tǒng)治手段，以激起人們的義憤和同情，這是全文的中心思想。（二）關(guān)于報(bào)告文學(xué)：《包身工》屬于報(bào)告文學(xué)。(同類題材有初中的《地質(zhì)之光》、《誰(shuí)是最可愛的人》)報(bào)告文學(xué)，是文學(xué)體裁的一種，散文的一類，是文藝通訊、速寫、特寫的總稱，是文學(xué)創(chuàng)作中的“輕騎兵”。
人教版新課標(biāo)高中物理必修1摩擦力說(shuō)課稿2篇
本節(jié)課是人教社物理必修1第三章第三節(jié)的內(nèi)容，編排在彈力之后。該節(jié)知識(shí)既是力學(xué)的基礎(chǔ)，也是組成整個(gè)高中物理知識(shí)的一塊“基石”，所以這節(jié)內(nèi)容的教學(xué)如何引領(lǐng)學(xué)生自主積極地探究摩擦力產(chǎn)生的條件和影響因素，體驗(yàn)?zāi)Σ亮μ攸c(diǎn)規(guī)律的發(fā)生過程是本節(jié)課的重點(diǎn)，應(yīng)高度重視本節(jié)教學(xué)過程；由于摩擦力問題的復(fù)雜性，且在具體問題中又表現(xiàn)出“動(dòng)中有靜，靜中有動(dòng)”，尤其靜摩擦在許多情形下似乎又是“若有若無(wú)，方向不定”，因此，對(duì)于初學(xué)者也是有一定難度的。也正是由于教材內(nèi)容的上述特點(diǎn)，本節(jié)課又易于激起學(xué)生的求知欲，易于培養(yǎng)學(xué)生的辯證觀點(diǎn)，易于錘煉學(xué)生的物理素質(zhì)。要充分用好該節(jié)教材內(nèi)容，深入挖掘知識(shí)間的有機(jī)聯(lián)系，對(duì)學(xué)生開展針對(duì)性的思維訓(xùn)練，進(jìn)而提高學(xué)生應(yīng)用物理知識(shí)解決實(shí)際問題的能力和創(chuàng)新思維能力。高中物理《課標(biāo)》對(duì)該知識(shí)點(diǎn)的要求是，“通過實(shí)驗(yàn)認(rèn)識(shí)滑動(dòng)摩擦、靜摩擦的規(guī)律，能用動(dòng)摩擦因數(shù)計(jì)算摩擦力”。其中，對(duì)靜摩擦力規(guī)律的認(rèn)識(shí)應(yīng)該包括最大靜摩擦力。

一、教學(xué)目標(biāo)：基于對(duì)教材的理解和分析，根據(jù)《課程標(biāo)準(zhǔn)》和學(xué)生的知識(shí)水平及認(rèn)知特點(diǎn)。我制定了這樣的教學(xué)目標(biāo)。（1）知識(shí)目標(biāo)：理解社會(huì)實(shí)踐的發(fā)展是文化創(chuàng)新的動(dòng)力和源泉，認(rèn)識(shí)文化創(chuàng)新的作用以及文化創(chuàng)新在新時(shí)代的價(jià)值和作用。（2）能力目標(biāo)：能夠分析事例，說(shuō)明社會(huì)實(shí)踐是文化創(chuàng)作和發(fā)展的重要根源，從而培養(yǎng)學(xué)生的比較分析能力、辯證思維能力（3）情感態(tài)度與價(jià)值觀目標(biāo)：通過本框教學(xué)，使學(xué)生明確文化創(chuàng)新的重大作用，激發(fā)學(xué)生投身建設(shè)中國(guó)特色社會(huì)主義偉大實(shí)踐而進(jìn)行文化創(chuàng)新的熱情，從而培養(yǎng)學(xué)生的創(chuàng)新精神、愛國(guó)情感和民族自豪感，增強(qiáng)學(xué)生進(jìn)行文化創(chuàng)新的責(zé)任感和使命感。二、教材分析本框題內(nèi)容包括情景導(dǎo)入--不盡的源泉，情景分析--巨大的作用、深刻的意義和情景回歸--呼喚文化創(chuàng)新的時(shí)代三個(gè)目題。其內(nèi)在的邏輯關(guān)系是由第一目題導(dǎo)入社會(huì)實(shí)踐是文化創(chuàng)新的源泉，也是文化創(chuàng)新的動(dòng)力的觀點(diǎn)，第二目是對(duì)文化創(chuàng)新的作用進(jìn)行理論上的分析。第三目情景回歸，當(dāng)今時(shí)代呼喚文化創(chuàng)新。
人教版新課標(biāo)高中物理必修2能量守恒定律與能源說(shuō)課稿3篇
（3）內(nèi)陸和中西部城鎮(zhèn)主要以煤和火電為主；廣大農(nóng)村和邊遠(yuǎn)地區(qū)大多正從使用農(nóng)作物秸稈等生物能源。（4）人均能源資源不足。我國(guó)是世界第三大能源生產(chǎn)國(guó)和第二大能源消費(fèi)國(guó)，而我國(guó)能源短缺，特別是油氣資源短缺已成為制約我國(guó)經(jīng)濟(jì)發(fā)展的重要因素。相關(guān)數(shù)據(jù)——煤炭、石油和天然氣的人均資源占有量只有95t，世界平均值為209t，約是世界人均值的1/2；我國(guó)人均石油可采儲(chǔ)量3t，世界平均值為28t，約為世界平均值的1/10。我國(guó)人均能源消費(fèi)量不足1.2噸標(biāo)準(zhǔn)煤，居世界89位，不足世界人均能源消費(fèi)水平的一半，僅占發(fā)達(dá)國(guó)家的1/5～1/10。其中人均消費(fèi)650kg標(biāo)準(zhǔn)煤，是世界平均額的95%；人均消費(fèi)石油相當(dāng)145kg標(biāo)準(zhǔn)煤，為世界平均數(shù)的16.8%；人均消費(fèi)天然氣相當(dāng)17.7kg標(biāo)準(zhǔn)煤，為世界平均數(shù)的3.9%；人均消費(fèi)電力501.5kWh，為世界平均水平的25%。（5）是能源消費(fèi)結(jié)構(gòu)不合理，突出存在著一低兩高：即電能消費(fèi)比例低，非商品生物能源消費(fèi)量高，一次性商品能源消費(fèi)中原煤消費(fèi)比重高。原煤消費(fèi)達(dá)到75%，遠(yuǎn)高于26.2%的世界平均水平。
