人教版高中語文必修3《師說》說課稿3篇
一、設計理念教學設計堅持少講多學、以學為主的教學理念，重視學培養(yǎng)生的學習興趣，要充分調(diào)動學生學習的積極性和主動性，充分發(fā)揮學生的主體性。教師要以組織者、引導者、合作者的角色參與到教學活動中去。力圖通過導學案努力培養(yǎng)學生的自學習慣和自學能力。二、教材分析與處理1、教材的地位與作用：必修三第三單元所選的文言文都是古代的議論性散文。本課是“唐宋八大家”之首、中唐古文運動的倡導者韓愈的力作，是唐宋散文中的名篇，具有很強的代表性。通過這篇自讀課的學習，能使學生了解唐宋散文的風貌，更能使學生進一步積累文言文基礎知識，提高學生的文言文閱讀欣賞能力，從而提升學生的文言文自讀能力。2、教學目標：《高中語文課程標準》要求高中學生能閱讀淺易文言文，能借助注釋和工具書，理解詞句含義，讀懂文章內(nèi)容；了解并梳理常見的文言實詞、文言虛詞、文言句式的意義或用法，注重在閱讀實踐中舉一反三；對文章有一定的分析欣賞能力。高一的學生對于文言文的知識還在積累階段，應該注重基礎知識的積累和一定量的誦讀。對此，我將教學目標確定為：
人教版高中歷史必修1八國聯(lián)軍侵華說課稿
4,教師重點點撥以下幾個問題⑴廊坊戰(zhàn)役:義和團浴血奮戰(zhàn),對敵人毫不退縮, 其勝利，挫敗了西摩爾聯(lián)軍進犯北京的計劃，沉重打擊了侵略者的氣焰，粉碎了所謂“西方軍隊無敵”的神話。這是對學生進行愛國主義的重要素材之一，教師重點點撥突出其情感教育的重要作用。⑵讓學生（閱讀教材小字和材料，結(jié)合插圖，認清八國聯(lián)軍對中國人民犯下的滔天罪行。）并讓學生分組探討自己的看法,一方面培養(yǎng)學生的語言表訴能力,另一方面通過學生的訴說激發(fā)學生的愛國情感,樹立落后就要挨打的觀念.⑶指導學生通過對條約主要內(nèi)容進行了分析，并自然得出結(jié)論：清政府完全成為帝國主義統(tǒng)治中國的工具，中國完全陷入半殖民地半封建社會。讓學生逐步學會分析和歸納能力(4)進行拓展訓練出示中國近代史上列強的大規(guī)模的侵華戰(zhàn)爭和中國人民的反抗斗爭
人教版高中歷史必修3啟蒙運動說課稿
教材地位本課具有承上啟下的作用，前承文藝復興，后啟資產(chǎn)階級革命時代的到來，啟蒙運動為資本主義社會構(gòu)建了一套政治藍圖，具有前瞻性，是近代第二次思想解放運動。因此，本節(jié)內(nèi)容在整個教材中有著很重要的地位。教學目標1、知識目標：（1）幫助學生了解啟蒙運動的性質(zhì)、內(nèi)容和主要啟蒙 思想家及其主張。（2）理解啟蒙運動興起的背景、影響。2、能力目標：（1）在討論和探究過程中訓練學生的科學思維方法和自主學習的能力和掌握解題的方法。（2）通過指導學生閱讀啟蒙思想家的言論資料，培養(yǎng)學生對歷史資料的理解和歸納能力。3、情感價值目標：（1）培養(yǎng)人文意識，強化法治觀念。（2）培養(yǎng)學生的團結(jié)協(xié)作精神和競爭意識。教學重點、難點(1)教學重點：啟蒙思想家的主張及啟蒙運動的影響。
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。
人教版高中歷史必修3宋明理學說課稿3篇
陸王心學與程朱理學相比有何異同？生 不同點：在理的內(nèi)涵上不同，程朱理學認為“理”是貫通于宇宙、人倫的客觀存在，是一種普遍的規(guī)律準則；陸王心學認為心即理，是“良知”，認為人心便是世界萬物的本原。方法上也有不同：前者向外追究，“格物致知”；后者向內(nèi)探求，“發(fā)明本心”以求理，克服私欲、回復良知。生 相同點：都提出了一個宇宙、社會、人生遵循的“理”。師 對。程朱理學是客觀唯心主義，陽明心學是主觀唯心主義。這兩者的分歧是理學范圍內(nèi)的分歧，其基本思想是一致的。師 宋明理學與漢唐以前的儒學比較，最大的特點在于批判地吸收了佛教哲學的思辨結(jié)構(gòu)和道教的宇宙生成論，將儒家的倫理學說概括升華為哲學基本問題。其實質(zhì)是把佛、道“養(yǎng)性”“修身”引向儒家的“齊家”“治國”“平天下”，對儒家的綱常道德給予哲學論證，使之神圣化、絕對化、普遍化，以便深入人心，做到人人遵而行之。
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。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。
人教版高中生物必修2染色體變異說課稿
四、說教學程序（一）.溫故知新、導入新課復習提問:基因突變導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:對于一個生物體來說，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)量均會發(fā)生改變，從而導致生物性狀的改變，這就屬于染色體變異。（二）.把握重點、突破難點重點的把握：1、染色體結(jié)構(gòu)的變異播放影片:貓叫綜合征幼兒。讓學生觀察: 患兒哭聲輕、音調(diào)高，很像貓叫。教師補充: 患兒的征狀---兩眼較低、耳位低下，存在著嚴重的智力障礙。闡述病因---染色體片段缺失

人教版高中地理必修2煤城焦作出路何在說課稿
分析過焦作市的地理概況和產(chǎn)業(yè)優(yōu)勢后，就需要針對由于資源枯竭所帶來的問題提出合理化的建議。既然是談經(jīng)濟轉(zhuǎn)型，就應該將話題的范圍明確在這一領(lǐng)域內(nèi)。通過材料3的相關(guān)內(nèi)容，我們了解到焦作市需要在產(chǎn)業(yè)結(jié)構(gòu)調(diào)整、培育新的優(yōu)勢產(chǎn)業(yè)、增強綜合競爭力等三個整改方針上下功夫。因而引導學生針對優(yōu)勢與不足提出建議，以三個整改方針為基準，衡量建議的可行性是鍛煉學生解決此類問題的有效途徑。在此我將教會學生的是解決問題方法而非案例的內(nèi)容，正所謂“授之以魚，不如授之以漁”。接下來針對學生的建議和教材資料分析所羅列的10點整改思路，由學生自由發(fā)言提出看法，通過教師的指導和學生的討論，進而確定經(jīng)濟轉(zhuǎn)型建議的具體方案。最后注意將建議與產(chǎn)業(yè)優(yōu)勢相對照，看建議是否都是圍繞著產(chǎn)業(yè)優(yōu)勢而提出的，這樣做會加深學生的印象，通過建議和優(yōu)勢的對應關(guān)系，將不難找出此類問題的解題思路。

人教版新課標高中物理必修1牛頓第二定律說課稿2篇
進一步引導學生思考利用數(shù)學知識可寫成等式F=kma學生很自然就會思考比列系數(shù)K應該是多少？通過教師引導學生舉例各國長度單位不同（如英國：英里、碼、英尺、英寸；中國：市里、市丈、市尺、市寸、市分 ）導致交流不便。為了適應各國交流需要國際計量局規(guī)定了一套統(tǒng)一的單位，稱為國際單位制 。取不同的單位制K是不同的，為了簡潔方便，在選取了質(zhì)量和加速度的國際單位（Kg, m/s2)時規(guī)定K=1。那么就有；F=ma為了紀念牛頓，就把能使1kg物體獲得1m/s2加速度的力稱做一牛頓，用符號N表示問題：實際物體受力往往不止一個，多個力情況應該怎么辦呢？平行四邊形法則進一步引導學生得出牛頓第二定律更一般的表達式: F合=ma思考.討論我們用力提一個很重的箱子，卻提不動它。這個力產(chǎn)生了加速度嗎？要是產(chǎn)生了，箱子的運動狀態(tài)卻并沒有改變。為什么？

②內(nèi)燃機的發(fā)明推動了交通運輸領(lǐng)域的革新。19世紀末，新型的交通工具——汽車出現(xiàn)了。1885年，德國人卡爾·本茨成功地制成了第一輛用汽油內(nèi)燃機驅(qū)動的汽車。1896年，美國人亨利·福特制造出他的第一輛四輪汽車。與此同時，許多國家都開始建立汽車工業(yè)。隨后，以內(nèi)燃機為動力的內(nèi)燃機車、遠洋輪船、飛機等也不斷涌現(xiàn)出來。1903年，美國人萊特兄弟制造的飛機試飛成功，實現(xiàn)了人類翱翔天空的夢想，預告了交通運輸新紀元的到來。③內(nèi)燃機的發(fā)明推動了石油開采業(yè)的發(fā)展和石油化學工業(yè)的產(chǎn)生。石油也像電力一樣成為一種極為重要的新能源。1870年，全世界開采的石油只有80萬噸，到1900年猛增至2 000萬噸。（3）化學工業(yè)的發(fā)展：①無機化學工業(yè)：用化學反應的方式開始從煤焦油中提煉氨、笨、等，用化學合成的方式，美國人發(fā)明了塑料，法國人發(fā)明了纖維，瑞典人發(fā)明了炸藥等。
