人教版高中生物必修2減數(shù)分裂和受精作用說課稿
一 減數(shù)分裂高一生物減數(shù)分裂說課稿各位評委、老師：大家好，我今天說課的題目是高中生物必修2第二章第一節(jié)〈〈減數(shù)分裂與受精作用〉〉第一部分減數(shù)分裂第一課時精子形成過程。接下來我就從以下幾個方面來說說這一節(jié)課。一、說教材1．教材地位和作用《減數(shù)分裂》這一部分內(nèi)容不僅是第二章的重點內(nèi)容，也是整本書的重點內(nèi)容之一。它以必修一學過的細胞學知識、染色體知識、有絲分裂知識和初中生殖種類知識為基礎。通過學習，使學生全面認識細胞分裂的種類、實質(zhì)和意義，為后面學習遺傳和變異，生物的進化奠定細胞學基礎。2．教學目標（1）知識目標：掌握減數(shù)分裂的概念和精子的形成過程；理解減數(shù)分裂和受精作用的意義。（2）能力目標：通過觀察減數(shù)分裂過程中染色體的行為變化，培養(yǎng)學生識圖、繪圖能力以及比較分析和歸納總結(jié)的能力。
人教版高中生物必修1降低化學反應活化能的酶說課稿
實驗是學習生物的手段和基礎，是培養(yǎng)學生分析問題、解決問題的能力及創(chuàng)造能力的載體。新課程倡導：強調(diào)過程，強調(diào)學生探索新知識的經(jīng)歷和獲得新知的體驗，不能在讓教學脫離學生的內(nèi)心感受，必須讓學生追求過程的體驗。并且每年高考都有對生物學實驗的考查，而且比例越來越重，而學生的失分比例大，主要在于他們沒有完整的生物實驗設計模式，考慮問題欠缺，本節(jié)安排在第二課時完整講述高中生物學實驗設計，是以學生在第一課時和前面探究實驗接觸的前提下，完整體驗生物實驗設計模式，為后面學習探究實驗打下基礎，也為培養(yǎng)學生分析問題、解決問題從一開始就打好基礎。五、說教學過程：第一課時聯(lián)系生活，導入新課，激發(fā)學生學習興趣→細胞代謝→問題探究，酶在代謝中的作用，掌握科學實驗方法→酶的本質(zhì)，運用方法，自主歸納獲取新知→小結(jié)練習，突出重點易化難點

人教版高中生物必修1細胞中的元素和化合物說課稿
一、說教材的地位和作用《細胞中的元素和化合物》是人教版教材生物必修一第二章第1節(jié)內(nèi)容?！都毎械脑睾突衔铩愤@一節(jié)，首先在節(jié)的引言中，明確指出自然界的生物體中的元素是生物有選擇地從無機自然界中獲得的，沒有一種元素是細胞特有的。但細胞與非生物相比，各元素的含量又大不相同。說明生物界與非生物界具有統(tǒng)一性和差異性。這部分內(nèi)容較為淺顯，但是結(jié)論非常重要，對于學生了解生物的物質(zhì)性具有重要意義二、說教學目標根據(jù)本教材的結(jié)構(gòu)和內(nèi)容分析，結(jié)合著高一年級學生的認知結(jié)構(gòu)及心理特征，我制定了以下的教學目標：1、知識目標：知道組成細胞的主要元素；知道為什么碳元素是構(gòu)成細胞的基本元素2、能力目標：學會檢測生物組織中的糖類、脂肪和蛋白質(zhì)的方法。（1）通過對C元素的分析，說明有機化合物形成的可能性及必然性，初步培養(yǎng)學生跨學科綜合分析問題的能力。（2）通過對組成細胞中的元素的百分比的分析，通過對不同化合物的質(zhì)量分數(shù)的學習，培養(yǎng)學生理解、思考和分析問題的能力。
人教版高中歷史必修3現(xiàn)代中國教育的發(fā)展說課稿
一、教材分析下面我來談一談對教材的認識：主要從教材的地位和作用、以及在此基礎上確立的教學目標、教學重難點這三個方面來談。首先，來談教材的地位和作用：本課教材內(nèi)容主要從三個方面向?qū)W生介紹了現(xiàn)代中國教育的發(fā)展狀況和趨勢：人民教育的奠基、動亂中的教育和教育的復興，全面講述了新中國教育的三個階段。本課是文化史中中國史部分的最后一課， 也是必修三冊書中唯一涉及教育的一課。而教育是思想文化史中的重要組成部分，江澤民同志在談到教育的時候曾經(jīng)說過，“百年大計，教育為本。教育為本，在于育人”。教育是關系國計民生的大事。學生通過學習新中國教育發(fā)展的史實，理解“科教興國”、“國運興衰，系于教育”的深刻含義。最終由此激發(fā)學生樹立“知識改變命運、讀書成就人生”的信念，樹立勤奮學習、成人成才、報效祖國、服務社會的崇高理想。故本課的教學有極大的現(xiàn)實意義。談完了教材的地位和作用，我再分析一下教學目標：
人教版高中歷史必修1世界多極化趨勢的出現(xiàn)說課稿2篇
(一)本課教材地位分析本課教材的主題是世界格局多極化趨勢的出現(xiàn)，在整個單元中有承前啟后的作用,前一課是它的大背景,后一課是它的延續(xù)。本課的核心問題是兩極格局下,20世紀六七十年代世界多極化趨勢的出現(xiàn)。通過走向聯(lián)合的歐洲、迅速崛起的日本、發(fā)展中國家的星期以及中國的崛起三方面內(nèi)容，反映了世界格局多極化趨勢的出現(xiàn)。在教學中，應注意利用學生對時事的關心與熟悉，引導學生進行相應的探究活動，使學生對世界格局的發(fā)展變化能夠認識準確和完整把握。（二）三維目標A．知識與能力1.通過對歐洲一體化的進程、日本經(jīng)濟迅速崛起、不結(jié)盟運動和中國振興的基本史實的學習，掌握20世紀六七十年代世界多極化趨勢出現(xiàn)的史實，理解其世界大背景和“多極化”的概念。2.通過西歐、日本、中國的崛起，理解經(jīng)濟決定政治，政治反作用于經(jīng)濟。
人教版高中歷史必修2世界經(jīng)濟的全球化說課稿2篇
【合作探索】經(jīng)濟全球化和經(jīng)濟區(qū)域集團化的關系？相互促進，相互制約。促進：經(jīng)濟全球化不平衡導致經(jīng)濟區(qū)域集團化，區(qū)域集團化是經(jīng)濟全球化的具體表現(xiàn)，經(jīng)濟區(qū)域集團化是最終實現(xiàn)經(jīng)濟全球化的重要步驟和途徑，經(jīng)濟全球化則是區(qū)域經(jīng)濟集團化的最終歸宿。制約：但經(jīng)濟區(qū)域集團化短期內(nèi)對全球化不利。過渡：經(jīng)濟全球化讓世界得以發(fā)展，但也有不公平的因素，那么，誰來維護公平了？二 、世界貿(mào)易組織的建立師：世界貿(mào)易組織建立的主要原因是什么？生：⑴經(jīng)濟全球化的發(fā)展迅速；⑵關貿(mào)總協(xié)定存在許多弊端，不適應經(jīng)濟全球化發(fā)展的要求師：它是怎樣建立起來的？生：①1986年： 意大利 提出倡議②1993年：烏拉圭回合談判——把多邊貿(mào)易組織改名為世界貿(mào)易組織③1994年： 正式?jīng)Q定建立WTO④1995.1.1：WTO正式開始運作師：世貿(mào)組織特點是什么？宗旨是什么？生：規(guī)范化 法制化。促進各國市場開放，調(diào)解貿(mào)易糾紛，實現(xiàn)全球范圍內(nèi)的貿(mào)易自由化
人教版高中歷史必修2世界經(jīng)濟的區(qū)域集團化說課稿2篇
一、 教材分析1、 教材地位和作用《當今世界的經(jīng)濟區(qū)域集團化》是人教版《歷史②》（必修）第八單元第二課的內(nèi)容。主要圍繞戰(zhàn)后世界經(jīng)濟中出現(xiàn)的經(jīng)濟區(qū)域集團化的趨勢，重點介紹了對世界經(jīng)濟影響最大的三大區(qū)域集團：歐洲聯(lián)盟、北美自由貿(mào)易區(qū)和亞太經(jīng)濟合作組織。從內(nèi)容上既銜接了70年代布雷頓森林體系瓦解后80年代出現(xiàn)的經(jīng)濟區(qū)域集團化的趨勢，又啟示了這種趨勢是經(jīng)濟全球化趨勢的一部分，提出了下節(jié)課的主題。具有承上啟下的作用。2、 教學目標根據(jù)高中新課程標準和知識與能力、過程與方法、情感態(tài)度價值觀三者統(tǒng)一的要求，我將本節(jié)課的教學目標定為以下的三大方面：1) 知識與能力：能夠讓學生理解三大區(qū)域經(jīng)濟集團建立的史實，認識三大區(qū)域經(jīng)濟組織在世界經(jīng)濟全球化進程中的影響和作用，增強學生辨證地觀察、分析歷史問題的能力。
人教版高中歷史必修2戰(zhàn)后資本主義的新變化說課稿2篇
2.“里根經(jīng)濟學”和“撒切爾主義”20世紀70年代，世界資本主義經(jīng)濟發(fā)展進入“滯脹”狀態(tài)后，各國政府紛紛尋找醫(yī)治這一新疾病的藥方，其中影響最大的是供應學派和貨幣學派。1979年，撒切爾夫人上臺擔任英國首相，率先采納了貨幣學派的主張。1981年，里根擔任美國總統(tǒng)后，以供應學派為依據(jù)，確立了自己政府的經(jīng)濟政策。由于兩人的經(jīng)濟政策都在一定程度上緩解了本國的經(jīng)濟危機，并有一套理論體系支撐，因此經(jīng)濟學家們分別稱之為“里根經(jīng)濟學”和“撒切爾主義”。實際上，“里根經(jīng)濟學”和“撒切爾主義”有許多相同之處，二者都提倡自由放任，強調(diào)市場調(diào)節(jié)作用，反對國家干預；二者都實行有利于富人的減稅政策，因此都曾被攻擊為“劫貧濟富”；二者都大力增加軍費開支，用加大政府消費來緩解危機。3.美國“新經(jīng)濟”戰(zhàn)后西方國家在凱恩斯主義指導下，暫時擺脫了三十年代那種嚴重的大蕭條局面，但由于長期實行擴張性財政貨幣政策和對社會需求進行管理的政策，各資本主義國家經(jīng)濟又出現(xiàn)新的危機，即“滯脹”（生產(chǎn)停滯和通貨膨脹），凱恩斯主義由此走向沒落。
人教版高中生物必修2現(xiàn)代生物進化理論的主要內(nèi)容說課稿
什么因素可以阻止種群間基因交流呢？由此可引出隔離的概念。學生初步理解隔離的概念之后，可以安排學生討論隔離的各種可能的方式，教師歸納出隔離的類型。然后組織學生閱讀分析教材中的“資料分析”，組織討論“資料分析”中提出的幾個問題。最后教師應強調(diào)，一般情況下，地理隔離是生殖隔離的先決條件，生殖隔離一旦形成，原來屬于一個物種的兩個種群，就成了兩個物種。關于“共同進化與生物多樣性的形成”內(nèi)容的教學，可以學生自學為基礎，教師提出一些具有啟發(fā)性的問題，師生共同歸納總結(jié)的方式推進教學過程。使學生理解共同進化的含義，無機環(huán)境的變化、無機環(huán)境的復雜化和多樣化、有性生殖的出現(xiàn)和生態(tài)系統(tǒng)結(jié)構(gòu)的復雜化和多樣化對生物多樣性形成的作用。最后，組織學生討論生物進化理論在發(fā)展。
