人教版高中歷史必修2羅斯福新政說課稿2篇
1、教材的地位作用本課是新人教版普通高中歷史必修Ⅱ第六單元第18課的內(nèi)容，闡述羅斯福新政的背景、措施、影響。從單元知識安排看，本課與第17課《空前嚴(yán)重的資本主義世界經(jīng)濟(jì)危機(jī)》、19課《戰(zhàn)后資本主義的新變化》共同詮釋第六單元課題——《資本主義世界經(jīng)濟(jì)政策的調(diào)整》。說明了“資本主義經(jīng)濟(jì)理論和政策隨著資本主義發(fā)展而不斷調(diào)整的特點(diǎn)”,凸顯了“市場調(diào)節(jié)”和“國家干預(yù)”在經(jīng)濟(jì)發(fā)展中的重要性。從知識體系看，它是學(xué)生學(xué)習(xí)了第一次工業(yè)革命后自由資本主義、第二次工業(yè)革命后的壟斷資本主義等之后出現(xiàn)的，既是對上述知識的鞏固與綜合運(yùn)用，又為學(xué)生學(xué)習(xí)必修二的相關(guān)內(nèi)容打下基礎(chǔ)，有承上啟下的作用。本課三個子目從邏輯上看又是遞進(jìn)關(guān)系。第一個子目“臨危受命”承上啟下，說明了羅斯福上臺的歷史背景具有臨危受命的特點(diǎn)，第二個子目“實施新政”講述了羅斯福新政的主要內(nèi)容，第三個子目“擺托危機(jī)困境”主要講述了羅斯福新政的影響。
人教版高中歷史必修1甲午中日戰(zhàn)爭說課稿
3．甲午中日戰(zhàn)爭中國戰(zhàn)敗的原因 對于“中國戰(zhàn)敗的原因”這一難點(diǎn)的突破，主要通過設(shè)置問題“中國之?dāng)≡趯嵙d于日本嗎？”通過幻燈片全方位分析其實中國的綜合國力當(dāng)時是強(qiáng)于日本的。并且在戰(zhàn)前，日本毫無取勝的把握。讓學(xué)生結(jié)合剛學(xué)習(xí)過的戰(zhàn)爭原因和經(jīng)過進(jìn)行討論，從多方面分析中國戰(zhàn)敗的原因。經(jīng)過討論，學(xué)生可以得出以下結(jié)論：避戰(zhàn)自保方針，沒有積極備戰(zhàn)，將領(lǐng)臨陣脫逃，教師肯定并總結(jié)答案進(jìn)行補(bǔ)充。中日對比：中國士兵出身農(nóng)民，軍事訓(xùn)練落后，散兵游勇；日本士兵出身武士，訓(xùn)練有素；中國將領(lǐng)大多臨陣脫逃，并相互猜忌，受當(dāng)時惡劣的官風(fēng)影響；李鴻章深知北洋海軍實情，缺乏軍費(fèi)，軍備廢弛。為政治資本奉行避戰(zhàn)自保政策，慈禧太后挪用海軍軍費(fèi)過壽，支持李鴻章。使中方處于被動的局面，一再貽誤戰(zhàn)機(jī)。而日本在天皇的帶動下，全民備戰(zhàn)，做了充分的戰(zhàn)爭準(zhǔn)備。
人教版新課標(biāo)高中物理必修1彈力說課稿3篇
基于以上分析，為使本堂課圍繞重點(diǎn)、突破難點(diǎn)，同時讓學(xué)生在課堂教學(xué)中能力得到提高，我設(shè)計如下教學(xué)過程。（一）創(chuàng)設(shè)情景認(rèn)識形變由同學(xué)們已有的形變知識入手，引入新課。教師演示：①彈簧的壓縮形變；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)的吹拂下會不會擺動，發(fā)生形變嗎？演示微小形變放大實驗：由于這種形變不容易觀察，會使學(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驗。為什么光點(diǎn)會往下移？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)計意圖：使學(xué)生知道“放大”是一種科學(xué)探究的方法。]
人教版新課標(biāo)高中物理必修1摩擦力說課稿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)知識既是力學(xué)的基礎(chǔ)，也是組成整個高中物理知識的一塊“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?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“動中有靜，靜中有動”，尤其靜摩擦在許多情形下似乎又是“若有若無，方向不定”，因此，對于初學(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，深入挖掘知識間的有機(jī)聯(lián)系，對學(xué)生開展針對性的思維訓(xùn)練，進(jìn)而提高學(xué)生應(yīng)用物理知識解決實際問題的能力和創(chuàng)新思維能力。高中物理《課標(biāo)》對該知識點(diǎn)的要求是，“通過實驗認(rèn)識滑動摩擦、靜摩擦的規(guī)律，能用動摩擦因數(shù)計算摩擦力”。其中，對靜摩擦力規(guī)律的認(rèn)識應(yīng)該包括最大靜摩擦力。

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)生能在了解詩歌創(chuàng)作的時代背景的情況下通過反復(fù)誦讀詩歌，把握其中豐富的意象，領(lǐng)悟詩歌獨(dú)特的意境和詩人所要表達(dá)的情感?！队晗铩肥乾F(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“雨巷詩人”的雅號。本單元以《雨巷》為例子給學(xué)生展示了象征主義詩歌的特點(diǎn)，《雨巷》運(yùn)用了象征性的抒情手法。詩中那狹窄陰沉的雨巷，在雨巷中徘徊的獨(dú)行者，以及那個像丁香一樣結(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》的另一個突出的藝術(shù)特色。詩中運(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歌的方法

4、本文的重點(diǎn)是說辭，雖僅百余字，卻委婉曲折，步步進(jìn)逼，層層深入，表現(xiàn)出高超的勸說藝術(shù)、游說技巧。讓學(xué)生細(xì)細(xì)品味并概括說辭中包含幾層意思。第一層（“秦、晉圍鄭，鄭既知亡矣”），分析形勢，以退為進(jìn)，博得好感。第二層（“若亡鄭而有益于君”至“君之薄也”），亡鄭陪鄰，動搖聯(lián)盟。第三層（“若舍鄭以為東道主”至“君亦無所害”），存鄭有益，利益引誘。第四層（“且君嘗為晉君賜矣”至“唯君圖之”），追溯歷史，深入離間。可見燭之武面對大國的君主，巧舌如簧，不卑不亢，從容辭令，既不刺激對方也不失本國尊嚴(yán)，語言的分寸掌握得恰到好處。表現(xiàn)出燭之武機(jī)智善辯的外交才能。5、面對風(fēng)云突變的局勢，晉侯沒有感情用事，而表現(xiàn)了清醒的頭腦和理智的判斷。這種隱忍不發(fā)、隨機(jī)應(yīng)變的胸懷和謀略，正是晉文公終成霸業(yè)的根本原因。設(shè)計意圖：本環(huán)節(jié)的重點(diǎn)是全面把握燭之武這一人物性格特征，以及退秦師過程中體現(xiàn)出的非凡的膽識以及高超的謀略和語言藝術(shù)。
人教版高中生物必修1細(xì)胞分化說課稿
在講述細(xì)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(xì)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(xì)胞的出現(xiàn)就是細(xì)胞分化的結(jié)果，所以說，細(xì)胞的分化是生物體發(fā)育的基礎(chǔ)。在講到細(xì)胞全能性的時候，要多給學(xué)生舉些關(guān)于細(xì)胞全能性的例子，如植物組織培養(yǎng)、克隆技術(shù)等等，讓學(xué)生從實際的例子中真正的悟出細(xì)胞全能性的含義。此外，還要重視教材中的疑問，適當(dāng)對題目進(jìn)行引申,使它的作用更加突出，有利于學(xué)生對知識的串聯(lián)、積累、加工，從而達(dá)到舉一反三的效果。怎樣來解釋細(xì)胞的全能性呢？這主要以講授法來解釋了，細(xì)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(xì)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(dá)，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。
