人教版高中語文必修3《過秦論》說課稿3篇
本文篇幅較長，并且有一字句不易理解，因而對高一學生來說完全讀懂內(nèi)容有一些困難。這樣的話，老師就要做好引導工作，把一些難點，或是出現(xiàn)詞類活用比較多，局勢比較特殊的句子，老師可以先給學生畫出來，存疑，或是與同學們一起討論解決。對那些不易懂的字詞就引導學生聯(lián)系上下文提供的語境、前后涉及的情節(jié)加以推測、判斷，以培養(yǎng)學生依據(jù)文脈推斷詞義的好方法。要求學生點出重點實詞、框出通假字，主要是為幫助學生積累和掌握一些文言文中常見的一詞多義、異讀現(xiàn)象、古今異義和通假現(xiàn)象的詞語，并進一步得出規(guī)律，指導今后的文言文學習。詞類活用和特殊句式在文言文翻譯中難度較大，也是本文教學的兩大難點。要求學生標出有活用現(xiàn)象的字和劃出句式特殊的句子，是基于兩點考慮：1、積累一定數(shù)量的第一手例句；2、引導學生加以分類，找出每類的相同特征，并抽取出來形成規(guī)律性的東西，從而上升到理性認識，使學生能由學會一個到會學多個。翻譯過程中注重指導學生養(yǎng)成用符號法表示重點字句的好習慣，如點、框、圈、劃線等符號應(yīng)約定一致，便于突出翻譯中的重點、難點及復習。我的提示著重歸納了實詞“制”“亡”“遺”“利”等，名詞活用、形容詞活用、使動用法，被動句、狀語后置句。
人教版高中語文必修3《琵琶行 并序》說課稿2篇
說教材A．教材簡析《琵琶行（并序）》是人教版《普通高中課程標準實驗教科書語文》必修3第二單元的一篇講讀課文。本單元學習的是唐代詩歌，共七首詩?！杜眯校ú⑿颍肥翘拼F(xiàn)實主義詩人白居易寫的一首歌行體長篇敘事詩，是我國古代敘事詩和音樂詩中的“千古絕喝”。詩歌主題鮮明、人物形象生動，抒情真切細膩，具有深刻的思想內(nèi)容和卓越的藝術(shù)技巧。B．教學目標《全日制普通高中高級中學語文教學大綱》明確要求我們：在閱讀教學過程中要引導學生“感受文學形象，品味文學作品的語言和藝術(shù)技巧，初步鑒賞文學作品”。而本單元的教學要求是培養(yǎng)學生詩歌鑒賞的能力。根據(jù)教學大綱和單元教學要求，結(jié)合本課特點，我制定本課的教學目標是：1．知識目標：了解文學常識；積累重點文言實詞；品味主旨句“同是天涯淪落人，相逢何必曾相識”的內(nèi)涵；感知作者把音樂描寫與聽者、演奏者的感情融為一體的寫作特點。
人教版高中語文必修3《勸學》說課稿3篇
《勸學》是普通高中課程標準試驗教科書語文必修三第三單元的重點篇目，該文集中反映著名思想家荀子在學習問題上的觀點和精彩斐然的論證藝術(shù)。該單元所選課文都是古代的議論性散文。通過本單元的學習在于讓學生感受我國傳統(tǒng)文化的精神，掌握基礎(chǔ)的文言語法知識，學習如何清晰有力的表達自己的思想和見解。本文安排在單元的第一篇，如何指導學生學好這篇課文，是實現(xiàn)“授之以漁”，樹立學生學好文言文的信心，掌握文言學習方法的關(guān)鍵。根據(jù)新課標倡導從“知識與能力”、“過程與方法”、“情感態(tài)度與價值觀”三方面出發(fā)設(shè)計課程目標的要求和高一的學生對于文言文的知識還在積累的階段，應(yīng)該注重基礎(chǔ)知識的積累和一定量的誦讀的實際情況。我擬確定以下教學目標：1，了解荀子論述學習的思想，明確學習要靠積累、堅持不懈、專心致志的道理。2，掌握積累文言實詞、虛詞，活用、古今異議等現(xiàn)象和固定句式。
人教版高中語文必修3《宇宙的邊疆》說課稿2篇
（有的恒星旋轉(zhuǎn)平穩(wěn)均衡，有些恒星是因快速旋轉(zhuǎn)而變了形。作者以擬人的手法，生動形象地描述，仿佛向我們展示了不同恒星的性情：有的穩(wěn)重沉靜，有的急切躁動。讀來生動有趣，妙趣橫生。）(3)我們探索宇宙的時候，既要勇于懷疑，又要富于想象。想象經(jīng)常能夠把我們帶領(lǐng)到嶄新的世界，沒有想象，我們就處處碰壁。懷疑可以使我們擺脫幻想，還可以檢驗我們的推測。（對于未知領(lǐng)域的探索是需要懷疑和想象的，想象是科學的翅膀，敢于想象，并不斷地探索驗證，所謂“大膽假設(shè)，小心求證”懷疑否定舊知，產(chǎn)生新知。作者以簡潔的語言闡述了想象和懷疑看似矛盾的兩者在宇宙探索中的相輔相成，和諧統(tǒng)一。作者不囿于介紹宇宙知識，還發(fā)表自己的見解。）(4)我認為宇宙里很可能到處都充滿著生命，只是我們?nèi)祟惿形窗l(fā)現(xiàn)而已。我們的探索才剛剛開始。
人教版高中語文必修3《祝?！氛f課稿3篇
各位評委老師，大家好。我說課的題目是《祝福》。一、說教材（一）教材所處的位置和地位高中語文新課程教材必修五本書，共有2個單元中外小說單元。一個必修3的第一單元，一個是必修5的第一單元，共六篇文章。（《林黛玉進賈府》《祝福》《老人與?！贰读纸填^風雪山神廟》《裝在套子里的人》《邊城》）《祝?！肥菍儆谇罢摺Ｐ≌f是擁有眾多讀者的一種文體，它可以多方面刻畫人物性格，描摹人物心理，完整地表現(xiàn)人物之間的沖突，還可以具體生動地再現(xiàn)人物生活的環(huán)境，因此在反映復雜的社會生活方面具有獨特優(yōu)勢。所以學習小說這種文學樣式，也是有助于學生學會鑒賞小說的基本方法，為將來的小說閱讀打下基礎(chǔ)。魯迅的《祝?！肥侵袊F(xiàn)代小說的精品，當中的人物祥林嫂也是魯迅小說中與阿Q、孔乙己三個最為出名的人物之一。研讀好這篇文章，對將來小說的閱讀，小說中人物的理解，甚至小說的寫作都有深廣意義。
人教版高中歷史必修2大眾傳媒的變遷說課稿
教學內(nèi)容與分析本課內(nèi)容是大眾傳媒的變遷，首先解題，了解什么是大眾傳媒。大眾傳媒就是傳播大眾信息的媒體，進入近代社會以來，人與人之間的聯(lián)系變得越來越密切，社會化程度大大加深，需要有一種大眾化、傳播速度快、傳播范圍廣的媒介作為人與人之間進行信息溝通的渠道，人類社會的傳媒手段應(yīng)運而生，可由學生總結(jié)出有哪些主要的方式。報刊、影視、廣播，這三種大眾傳播媒體的依次出現(xiàn)，給人們的生活方式帶來了巨大的變化，被稱為三大媒介。由于互聯(lián)網(wǎng)同報紙、廣播和電視三大媒介一樣，具有傳播信息的功能，所以被稱為“第四媒介”，即“網(wǎng)絡(luò)媒介”。通過本節(jié)課的學習使學生了解中國近代社會生活的變化，體會歷史和時代發(fā)展的必然性，能夠站在發(fā)展的角度、用歷史的眼光思考問題。
人教版高中歷史必修1辛亥革命說課稿2篇
三、辛亥革命的結(jié)局1.袁世凱竊取革命果實由課件給出竊取革命果實的簡單過程，幫學生理清思路，創(chuàng)設(shè)問題情境，由學生分析革命果實被竊取的原因，教師給以補充并揭示根本原因，貫穿整個革命的資產(chǎn)階級的軟弱性和妥協(xié)性，再次加深對難點的理解。2.歷史功績辛亥革命性質(zhì)、功績由學生閱讀書本進行總結(jié)，再加以補充讓學生在書本上做好記錄，強調(diào)最大功績是結(jié)束了兩千多年的君主專制政體。辛亥革命的失敗及其評價很易搞成生硬的一言堂形式，可以從多種角度把學生思維調(diào)動起來。這里采用列舉一個合作探究,自由討論的題目“有人認為辛亥革命因為沒有完成反帝反封建的革命任務(wù)而失敗，有人則認為辛亥革命是中國“從君主到民主”社會轉(zhuǎn)型的成功開始。你同意哪種看法？”要求同學們自由討論.各抒己見,大膽創(chuàng)新,言之在理即可.教師在一旁引導學生,活躍課堂氣氛.最后教者歸納總結(jié)學習歷史從不同的角度看問題可以得出不同的結(jié)論,學會用辯證的觀點看待歷史問題，對辛亥革命有個全面的認識。
人教版高中生物必修1細胞的癌變說課稿
5．5癌癥的預(yù)防作為本節(jié)最重要內(nèi)容，且與生活息息相關(guān)，我采用老師引導、學生討論總結(jié)的方法進行教學。從生活各方面總結(jié)出保健良方 ，既對知識有很好應(yīng)用，又體現(xiàn)對生命的熱愛。此時，本節(jié)課達到高潮，同學們意氣風發(fā)，熱烈討論，實現(xiàn)本節(jié)課的教學目標。5．6 癌癥的治療通過講述癌癥治療方法的副作用，激發(fā)學生探究生物學欲望，激勵學生立志除癌。 在此，我選用一則關(guān)于一名癌癥晚期病人運用心理療法成功戰(zhàn)勝癌癥的故事，在于對不同層次的學生進行多方面啟發(fā)教育，體現(xiàn)面向全體學生的課程理念。5．7 愉悅總結(jié)，及時反饋本節(jié)知識點零散，我將帶領(lǐng)學生回憶瀏覽本節(jié)內(nèi)容，使零散知識點系統(tǒng)化。在課堂反饋環(huán)節(jié)，我通過簡單練習采用分組競答的方式把握學生對知識的掌握程度，并給予表現(xiàn)突出的學生適當獎勵，這是本節(jié)課第三個亮點。競答既使課堂顯得緊湊、集中，又有利于形成學生的競爭意識，還使得學生的知識得以鞏固應(yīng)用。
人教版高中生物必修1細胞的衰老與凋亡說課稿
4、最后從生物的壽命引入，探討細胞的死亡。強調(diào)細胞死亡有兩種形式。(1).細胞壞死，它是由某些外界因素造成細胞急速死亡，是一種被動性死亡；(2).細胞凋亡，這是一種由特定基因控制的主動性死亡。細胞壞死與細胞凋亡在形態(tài)學和生物化學上有著明顯的區(qū)別。細胞凋亡有廣泛的生物學意義，比如胚胎發(fā)育期手的發(fā)育如果沒有細胞的調(diào)亡就不會有纖細的手指；如果沒有正常的細胞調(diào)亡，蝌蚪的尾部就不會消失，它將永遠不能變成青蛙……。正常的細胞調(diào)亡還肩負著維持各種組織器官固有體積和形態(tài)的功能；還會使機體內(nèi)異常的細胞得到及時清除，去處潛在的隱患；例如癌癥就是異常的細胞沒有及時死亡的結(jié)果……。因此細胞的正常死亡是生物體的一種非常重要的調(diào)節(jié)機制，是機體平衡細胞增殖，調(diào)節(jié)機體細胞樹木恒定的方式，是必不可少的生命過程。（15分鐘）5、課堂小結(jié)，可以把課堂傳授的知識盡快地轉(zhuǎn)化為學生的素質(zhì)；簡單扼要的課堂小結(jié)，可使學生更深刻地理解政治理論在實際生活中的應(yīng)用，并且逐漸地培養(yǎng)學生具有良好的個性。
人教版高中生物必修1細胞分化說課稿
在講述細胞分化的意義時，也可以用實例來解決，工廠的生產(chǎn)車間里不同的工人干著不同的工作，一件產(chǎn)品的產(chǎn)出需要這些工人才能創(chuàng)造出來，一個生物體就像一個車間一樣，不同的細胞各司其職，相互合作。工人的分工是主管調(diào)解出來的，而不同細胞的出現(xiàn)就是細胞分化的結(jié)果，所以說，細胞的分化是生物體發(fā)育的基礎(chǔ)。在講到細胞全能性的時候，要多給學生舉些關(guān)于細胞全能性的例子，如植物組織培養(yǎng)、克隆技術(shù)等等，讓學生從實際的例子中真正的悟出細胞全能性的含義。此外，還要重視教材中的疑問，適當對題目進行引申,使它的作用更加突出，有利于學生對知識的串聯(lián)、積累、加工，從而達到舉一反三的效果。怎樣來解釋細胞的全能性呢？這主要以講授法來解釋了，細胞全能性的體現(xiàn)需要在組織或器官離體后才能體現(xiàn)出來，每個細胞都包含著生物體的全套遺傳基因，通過基因選擇性的表達，使離體的組織或器官通過分裂和分化逐漸發(fā)育成完整的植株。

人教版高中英語必修3Astronomy the science of the stars說課稿3篇
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.

中班綜合《吃“傘”啦》說課稿
《吃“傘”啦！》出自南京師范大學出版的《幼兒園活動整合課程指導》中班上冊的“傘的世界”單元。在這個活動之前，小朋友已經(jīng)通過圍繞“傘”來展開的一系列活動，對傘的結(jié)構(gòu)、外形特征等有了一定的認識和了解。在這個基礎(chǔ)上，進一步深化，讓幼兒認識像傘一樣的植物，其中最有代表性的當然要數(shù)“蘑菇”了。小朋友平時在家里或在幼兒園里經(jīng)常都會吃到蘑菇，它的外形特殊，像一把小小的可愛的傘，小朋友看見蘑菇都會忍不住拿來玩一玩，摸一摸，甚至聞一聞。同時，蘑菇的味道鮮美，營養(yǎng)價值極高，可是由于它有一種特殊的味道，許多幼兒都不喜歡吃它，一種極有利于幼兒生長發(fā)育的優(yōu)秀食物就這樣被幼兒拒之嘴外，真的是很可惜！為了讓幼兒更好的了解這些可愛的“小傘”，并愿意與它成為“好朋友”，從而使幼兒能更加健康的成長，特此設(shè)計了《吃“傘”啦！》這一個綜合活動。
（老師稿）國旗下講話：為理想而奮斗
有同學要做一個科學家，發(fā)明各種各樣的機器，減輕人們的勞動；有的要做一名關(guān)心熱愛學生的好老師，為祖國的后代默默奉獻……是呀，同學們的理想很多，但理想也絕不是轉(zhuǎn)眼之間便可以實現(xiàn)的，而奮斗則是實現(xiàn)理想的橋梁，只有從基本的地方做起，循序漸進地朝著目標行進，才會慢慢地接近它、達到它。同學們，你們都知道電燈是誰發(fā)明的嗎？對了，是美國偉大的發(fā)明家愛迪生。在他光輝的一生中，他發(fā)明了上千種與我們生活息息相關(guān)的東西，比如照相機、投影儀……那么，你們知道嗎，又是什么成就他偉大的事業(yè)呢？是奮斗，是為自己的理想奮斗的精神。愛迪生在發(fā)明電燈時，要尋找一種即能節(jié)省電又能長時間使用的金屬作燈絲，為了能夠找到這樣的一種金屬，他一邊干活掙錢，一繼續(xù)不停地進行試驗。成千上萬次的失敗，沒有讓愛迪生灰心喪氣，反而激發(fā)了他堅強的斗志。最后，他終于成功了，找到金屬鎢作燈絲，也就是我們現(xiàn)在常用的電燈。
關(guān)于青春與理想的國旗下講話
青春與理想尊敬的老師們，親愛的同學們：大家好！我國旗下演講的題目是——《青春與理想》我們撇下無知迎來了屬于我們的青春。青春，讓我們肆無忌憚，暢然釋懷，體味風那樣的自由，感受云那般的自在，因為青春賦予我們的是生命的巔峰，我們無須成熟，我們不再無知，我們唯有執(zhí)著。人生是對理想的追求，理想是人生的指示燈，失去了這燈的作用，就會失去生活的勇氣。因此，只有堅持遠大的人生理想，才不會在生活的海洋中迷失方向。托爾斯泰將人生的理想分成：一輩子的理想，一年的理想，一個月的理想，甚至一天、一小時、一分鐘的理想。同學們，當你聽到這里，是否想到了自己的理想呢？
