人教版高中生物必修1細胞中的無機物說課稿
為了加強學生的理解，讓學生討論以下問題。由師生共同總結。播放一個短時視頻，讓學生認識到水的重要性后，展示節(jié)水標識，說明由來。細胞中的無機鹽這部分，我將展示圖表，并列出問題：表中哪些成分屬于無機鹽？為什么要在運動員喝的飲料中添加無機鹽？無機鹽在細胞的生活中起什么作用？然后展示廣告語，讓學生思考和討論以下問題，并得到答案。再閱讀課本，驗證自己的答案是否正確。關于無機鹽的作用較難理解，通過列舉人體生活與健康中的各種實例來加深感性認識，加強對理論知識的理解3、課堂小結，強化認識。（3—5分鐘）課堂小結，可以把課堂傳授的知識盡快地轉化為學生的素質；簡單扼要的課堂小結，可使學生更深刻地理解理論知識在實際生活中的應用，并且逐漸地培養(yǎng)學生具有良好的個性。4、板書設計我比較注重直觀、系統(tǒng)的板書設計，還及時地體現(xiàn)教材中的知識點，以便于學生能夠理解掌握。5、布置作業(yè)。
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亡就不會有纖細的手指；如果沒有正常的細胞調亡，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果……。因此細胞的正常死亡是生物體的一種非常重要的調節(jié)機制，是機體平衡細胞增殖，調節(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，可以把課堂傳授的知識盡快地轉化為學生的素質；簡單扼要的課堂小結，可使學生更深刻地理解政治理論在實際生活中的應用，并且逐漸地培養(yǎng)學生具有良好的個性。
人教版高中語文必修3《宇宙的邊疆》說課稿2篇
（有的恒星旋轉平穩(wěn)均衡，有些恒星是因快速旋轉而變了形。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，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，只是我們人類尚未發(fā)現(xiàn)而已。我們的探索才剛剛開始。
人教版高中歷史必修3輝煌燦爛的文學說課稿
教師：不同的時代造就了不同風格和不同精神內容的詩詞，請同學們回顧必修一和必修二兩宋中央集權的加強和經(jīng)濟的發(fā)展狀況。學生：回憶回答。教師：請同學們結合時代背景和詞的特點理解詞為什么能夠成為宋代文學的主流形式和標志？學生：兩宋時經(jīng)濟重心轉移到了南方，商業(yè)發(fā)展打破了時間和空間的限制，城市繁榮，市民數(shù)量不斷增加。詞的句子長短不齊，便于抒發(fā)感情，并且能夠歌唱，更能適應市井生活的需要。于是，詞成為宋代文學的主流形式和標志。教師：宋代文人地位提高，宋詞就是一個個時代的畫卷：大宋的悲歡離合都寫在了里面。除了詞之外，宋代民間還興起了一種新的詩歌形式，即散曲。學生：回答散曲的發(fā)展階段及特點、元曲的含義、特點。教師：在中國古代詩歌輝煌發(fā)展的同時，也產(chǎn)生了供人們閑來無事消遣的小說。
人教版高中生物必修2遺傳密碼的破譯說課稿
3、遺傳密碼的特點 連續(xù)性、簡并性、通用性5、課堂練習6、作業(yè)布置假如，我們利用(ACU)n核苷酸長鏈合成了含有蘇氨酸的多肽，那么蘇氨酸可能的密碼子有哪些？如何運用實驗方法確證蘇氨酸的密碼子究竟是什么？七、教學反思1、教材中豐富的科學史料，是我們在課堂上進行探究性學習活動的良好素材，教師要整理和運用好。千萬不要低估學生的思維能力，當學生的思維能力被你想方設法激發(fā)出來的時候，你會發(fā)現(xiàn)他們的創(chuàng)造力是無窮的。2、探究性學習的目的并不僅僅是問題的解決，更重要的是在探究過程中體驗和獲取科學研究方法，培養(yǎng)合作與分享的精神以及實事求是的科學態(tài)度，鍛煉思維能力，提高科學素養(yǎng)。3、學生是學習的主體，教師是引導者。我們要采取措施讓學生積極主動地參與到學習活動中來，通過他們的思考、討論、爭辯、合作等活動來獲取方法，建構知識。
人教版高中語文必修1《優(yōu)美的漢字》說課稿
明確：（1）結繩記事說。原始記事的一種方法。人類在沒有發(fā)明文字或文字使用尚不普遍時，常用在繩索或類似物件上打結的方法記錄數(shù)字，表達某種意思，用以傳達信息，處理事件。 （2）書畫說。（3）倉頡造字說。中國自古就有倉頡造字之說。文字的發(fā)明是人類發(fā)展史上一件石破天驚的大事，它將人們的思維、語言、經(jīng)驗以及復雜的社會現(xiàn)象記錄下來，使文化得以傳播交流、世代傳承。2、漢字的形體：中華民族五千年的歷史中，漢字的演變，從甲骨文－－金文－－大篆－－小篆－－隸書－－草書－－楷書－－行書，字形由象形到點橫豎撇捺的方塊字，經(jīng)歷了漫長的歲月。其中凝聚著民族的智慧，也體現(xiàn)出漢字逐步完善的過程，凸顯其方方正正、四平八穩(wěn)的特點。漢字又是一種文化的體現(xiàn)，那些經(jīng)過藝術處理的漢字或跳起了拉丁舞、有的如同酒醉的成龍打起了醉拳，更是讓我們感到的是在欣賞漢字在紙張上跳舞，所以：書法是“紙上的舞蹈”。請大家看到書上的相關內容，注意每一種形體的漢字的載體是什么，其功能又有什么不一樣。
人教版高中生物必修1細胞的癌變說課稿
5．5癌癥的預防作為本節(jié)最重要內容，且與生活息息相關，我采用老師引導、學生討論總結的方法進行教學。從生活各方面總結出保健良方 ，既對知識有很好應用，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，及時反饋本節(jié)知識點零散，我將帶領學生回憶瀏覽本節(jié)內容，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用。
人教版高中語文必修2《故都的秋》說課稿3篇
請一位朗誦水平較好的學生，有感情的朗讀課文12自然段，其他同學完成一項任務：這一段可否去掉？為什么？學生思考、圈畫、交流、討論，然后小組發(fā)言，其他小組補充，教師從旁予以點撥，引導學生進一步明確作者的思想情感。明確：作者要創(chuàng)造一種文化氛圍，于自然氣息之外再添一重文化氣息，與“故都”題旨暗合。從行文章法上看，這里是宕開文筆，縱橫議論，顯出深厚的文化底蘊和開闊的思路。這一段采用議論，通過古今中外的引證，說明感秋處處有，中國文人最突出，而秋“深味”非在中國北方莫屬，這其實還是為了突出故都之秋。（設計意圖：提高學生探究的能力，充分把握本文的教學內容，深刻體悟作者的情感，了解作者對秋的禮贊情感，從而突破教學難點。）
人教版高中歷史必修2大眾傳媒的變遷說課稿
教學內容與分析本課內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運而生，可由學生總結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。
人教版高中生物必修2DNA的復制說課稿
設問：DNA復制后兩個子代DNA分子與親代DNA分子是否完全相同？為什么？通過設問，讓學生進一步理解和鞏固DNA復制的全過程。接下來讓學生總結出DNA復制的四大基本條件：① 模板：開始解旋的DNA分子的兩條單鏈；② 原料：是游離在核液中的脫氧核苷酸；③ 能量：是通過水解ATP提供；④ 酶：酶是指一個酶系統(tǒng)，不僅僅是指一種解旋酶。最后通過以上分析，總結出DNA復制的意義以及在生活中的應用：意義：DNA通過復制，使遺傳信息從親代傳給子代，從而保證了物種的相對穩(wěn)定性，保持了遺傳信息的連續(xù)性，使物種得以延續(xù)。應用：目前DNA分子廣泛應用于刑事案件偵破等方面：如：DNA分子是親子鑒定的主要證據(jù)之一。把案犯在現(xiàn)場留下的毛發(fā)、血等進行分析作為破案的證據(jù)，與DNA有關。五、設計課堂練習：設計一題典型課堂練習：即有關半保留復制及計算的習題：
人教版高中歷史必修1新中國的民主政治建設說課稿2篇
（一）教材的地位新中國的成立是20世紀的一件大事。它結束了幾千年封建專制統(tǒng)治的歷史，開啟了中華民族發(fā)展的新紀元。本課側重這一時期一個非常顯著的特征，即制度的更新，它本身具有知識的延續(xù)性和鋪墊性。新中國的成立促進了社會經(jīng)濟的發(fā)展，也為祖國的統(tǒng)一奠定了重要基礎。（二）教學目標依據(jù)新課程以人為本，促進學生全面發(fā)展的要求，同時,針對高一年級學生具備一定基礎知識但掌握不牢固，對歷史興趣濃厚但又自制能力差的特點，我對本課的三維目標設定如下：見多媒體。（三）教學重點的確定及處理本課的主題是新中國的民主政治建設，這個問題的掌握對以后學習中國民主政治建設的進程有很大幫助，并且學生能力的提高也有賴于對它的認識，所以確定“人民代表大會制度的創(chuàng)立”是教學重點。
人教版高中歷史必修1從漢至元政治制度的演變說課稿2篇
二、君主專制的演進（即中央政治制度的演變）通過地方政治制度演變的學習，掌握方法以后，以學生歸納整理基本線索為主，教師適當點撥，注意糾錯。1． 漢承秦制，又有所變化。教師點撥強調繼承與發(fā)展兩個方面。創(chuàng)設情景：同學們看了電視連續(xù)劇《漢武大帝》后，知道漢武帝劉徹在繼位之后，就急于對西漢王朝的政治制度進行改革。那么，西漢初期中央政治制度的基本框架是怎樣的呢？漢武帝為什么要對它進行改革呢？改革后的西漢中央集權制度又是怎樣的呢？請大家議一議，想一想。主干知識：西漢初期的中央政治制度的最大特點是“漢承秦制”。具體表現(xiàn)在兩個方面：一是繼續(xù)實行皇帝制度，維護皇權，這一做法也為后來各王朝所沿用；二是在中央設立三公，分別掌管行政、監(jiān)察和軍事。到漢武帝時，“中朝”成為西漢重要的中央決策機構，尚書令的權力日益重要，以丞相為首的三公九卿的權力被削弱，演化為執(zhí)行機構。到了東漢光武帝時，進一步剝奪三公權限，擴大尚書的權力。
人教版高中歷史必修1夏、商、西周的政治制度說課稿3篇
二、教學目標：（一）知識與能力：學生了解夏商周期的政治制度的內容和特點，對不同的政治制度有一個較為全面的認識。在此基礎上，學生根據(jù)所學的知識，歸納和評價從夏到周政治發(fā)展的特點以及內在規(guī)律。（二）過程與方法：在學習的過程中，采用小組合作討論的形式，讓學生學會與他人合作與溝通，提高自主探究的技能。（三）情感態(tài)度與價值觀：政治制度的不斷更新是古人制度創(chuàng)新的結果，而這種制度的不斷更新也推動文明的發(fā)展。這是古代先民的智慧結晶，學生要引以為豪。而通過本課的學習，可以增強學生們的民族自豪感。三、說教科書：本課作為高中歷史教材的開篇，是認識整個古代政治文明史的起點，具有統(tǒng)領和示范作用。本課總共有三個子目,主要講述了夏商周的政治制度。主要介紹了夏朝公共權力的出現(xiàn)，分封制的內容、分封的對象、 “以嫡長子繼承制為核心的宗法制度”介紹了宗法制的來源、內容，以及禮樂制度的大致內容。

人教版高中英語必修4A taste of English Humor說課稿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
