  • 人教版高中語文必修1《包身工》說課稿2篇

    人教版高中語文必修1《包身工》說課稿2篇

    (一)解題:包身工──舊社會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(時間),在上海東洋紗廠里(地點),為外國人工作的女工(工作性質)。因為這些女工在進廠時已經簽訂了賣身契,失去了人身的自由權,所以被稱為“包身工”。標題中的“包身”二字,突出了帝國主義、封建勢力對中國女童工的殘酷剝削的罪行,控訴了他們的野蠻殘暴的統治手段,以激起人們的義憤和同情,這是全文的中心思想。(二)關于報告文學:《包身工》屬于報告文學。(同類題材有初中的《地質之光》、《誰是最可愛的人》)報告文學,是文學體裁的一種,散文的一類,是文藝通訊、速寫、特寫的總稱,是文學創(chuàng)作中的“輕騎兵”。

    三、文本中的句子解決完畢,大家對文本內容的理解更加深入了。請速度文本,思考:《論語》具體涉及了哪些方面的內容,體現了孔子什么觀點?明確:主要有治學、從政、修身養(yǎng)性和交友治道等方面,體現了孔子“克己復禮”的思想。四、 教師引導學生討論: 如何評價孔子的言行和觀點?從古至今人們對孔子有哪些評價?明確:1、春秋戰(zhàn)國時代, 孔子門人及其后學者均推尊孔子。門人中以子貢為代表,他對孔子贊美備至,奉如天人,把孔子比擬為高天、日月、木鐸,凡人是永遠不可企及的,認為孔子是天生的圣人,“仰之彌高,鉆之彌堅”。亞圣孟子認為孔子所行的“圣人之道”是遍及自然界和社會的至高準則。然而當時民間一般看法認為孔子是博學成名的大學者。

  • 人教版高中語文必修1《小狗包弟》說課稿

    人教版高中語文必修1《小狗包弟》說課稿

    探究、討論、交流:1、包弟討人喜歡,作者卻不得不將它送走,為什么?2、送走包弟后,作者為什么先是感覺輕松,隨后覺得沉重?3、“您的小狗怎樣?”這句話反復出現,有什么用意?4、“整整十三年零五個月過去了”“整整”一詞有什么作用?5、“滿園的創(chuàng)傷使我的心仿佛又給放在油鍋里熬煎”這句話如何理解?6、“我懷念包弟,我想向它表示歉意。”如何理解?學生各抒己見后教師結合材料發(fā)表看法明確總結特別是最后一個問題得出作者這發(fā)之心底的語言,不僅僅是歉意,更是發(fā)自靈魂深處的懺悔!是對生命的尊重,是一個有良知的作家對反省歷史的呼號。第三環(huán)節(jié)“認識你自己”——懺悔意識與我引導學生正視和反省成長過程中曾犯下過錯。并布置課后作業(yè):要求學生課后在本周隨筆中談反省懺悔后的感受。

  • 人教版高中語文必修1《燭之武退秦師》說課稿2篇

    人教版高中語文必修1《燭之武退秦師》說課稿2篇

    4、本文的重點是說辭,雖僅百余字,卻委婉曲折,步步進逼,層層深入,表現出高超的勸說藝術、游說技巧。讓學生細細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,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??梢姞T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,語言的分寸掌握得恰到好處。表現出燭之武機智善辯的外交才能。5、面對風云突變的局勢,晉侯沒有感情用事,而表現了清醒的頭腦和理智的判斷。這種隱忍不發(fā)、隨機應變的胸懷和謀略,正是晉文公終成霸業(yè)的根本原因。設計意圖:本環(huán)節(jié)的重點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出的非凡的膽識以及高超的謀略和語言藝術。

  • 人教版高中歷史必修1八國聯軍侵華說課稿

    人教版高中歷史必修1八國聯軍侵華說課稿

    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,結合插圖,認清八國聯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容進行了分析,并自然得出結論:清政府完全成為帝國主義統治中國的工具,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1鴉片戰(zhàn)爭說課稿2篇

    人教版高中歷史必修1鴉片戰(zhàn)爭說課稿2篇

    “第二次鴉片戰(zhàn)爭”爆發(fā)的原因的講析,可通過出示英國在鴉片戰(zhàn)爭后在中國與洪都拉斯的正當貿易對比表,讓學生觀察和創(chuàng)設情景來得出結論。戰(zhàn)爭的經過及影響,可以通過兩次鴉片戰(zhàn)爭形勢圖,以及一張相關的表格,從戰(zhàn)爭的根本目的、性質、過程及影響等方面來比較兩次戰(zhàn)爭的異同,從而讓學生理解掌握“戰(zhàn)火再燃”其實就是中英鴉片戰(zhàn)爭的繼續(xù)和擴大。并理解“第二次鴉片戰(zhàn)爭”的如何使中國社會半殖民地半封建化的程度大大加深了。并突出英法兩國殖民者在占領北京期間所犯的滔天罪行。3、結:結合板書設計,讓生自己總結這節(jié)課所學的內容,并通過課后習題練于講相結合,來鞏固本課知識。在此基礎上對本課線索及主要知識點進行簡要的梳理。4、課題延伸:教材后探究學習總結中的一段材料,即《英國駐華商務監(jiān)督義律致英國外交大臣巴麥尊的機密件》,讓學生究義律對中國發(fā)動鴉片戰(zhàn)爭原因的說辭來展開探討,啟發(fā)學生運用辨證唯物主義的基本觀點,澄清和批駁在在一問題上的一些錯誤和謬論,從而提高學生辨別是非的能力和批判的能力.

    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《空前嚴重的資本主義世界經濟危機》、19課《戰(zhàn)后資本主義的新變化》共同詮釋第六單元課題——《資本主義世界經濟政策的調整》。說明了“資本主義經濟理論和政策隨著資本主義發(fā)展而不斷調整的特點”,凸顯了“市場調節(jié)”和“國家干預”在經濟發(fā)展中的重要性。從知識體系看,它是學生學習了第一次工業(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的,既是對上述知識的鞏固與綜合運用,又為學生學習必修二的相關內容打下基礎,有承上啟下的作用。本課三個子目從邏輯上看又是遞進關系。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,第二個子目“實施新政”講述了羅斯福新政的主要內容,第三個子目“擺托危機困境”主要講述了羅斯福新政的影響。

    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:基因突變是基因結構發(fā)生改變,從而使遺傳信息改變,使蛋白質結構改變、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,其染色體的結構和數量都是穩(wěn)定的。但在自然條件或人為因素的影響下,染色體的結構和數量均會發(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、染色體結構的變異播放影片: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

    人教版高中政治必修1稅收及其種類說課稿

    在學生明確了稅收的含義之后,我將分別對稅收的三個基本特征進行解析。在講解了之后,并分別用實例對其進行說明,加深學生對知識點的印象。最重要的是,總結出關鍵的字眼,使得學生能夠清晰的區(qū)分出稅收的三個基本特征。將強制性概括為依法征稅、依法納稅;無償性概括為不具有償還性和返還型;固定性概括為規(guī)定應不應納稅、納什么稅、納多少稅。并跟學生指出,強制性是基本前提,無償性是核心。由此根據書上的內容,推導出稅收的三個基本特征相互之間的關系,即:三者缺一不可,統一于稅法。而且,無償性要求強制性,強制性保障無償性;而無償性與強制性又共同決定固定性。從而結束新課講授。3、課堂總結根據板書內容重新回顧本課學習的主要內容,包括稅收的含義,以及稅收的三個基本特征和它們之間的相互關系。4、作業(yè)布置讓學生預習稅收的種類的內容,尤其是增值稅和個人所得稅。同時了解父母每月所繳納的個人所得稅和怎么計算的。
