5．5癌癥的預(yù)防作為本節(jié)最重要內(nèi)容，且與生活息息相關(guān)，我采用老師引導(dǎo)、學(xué)生討論總結(jié)的方法進(jìn)行教學(xué)。從生活各方面總結(jié)出保健良方 ，既對(duì)知識(shí)有很好應(yīng)用，又體現(xiàn)對(duì)生命的熱愛(ài)。此時(shí)，本節(jié)課達(dá)到高潮，同學(xué)們意氣風(fēng)發(fā)，熱烈討論，實(shí)現(xiàn)本節(jié)課的教學(xué)目標(biāo)。5．6 癌癥的治療通過(guò)講述癌癥治療方法的副作用，激發(fā)學(xué)生探究生物學(xué)欲望，激勵(lì)學(xué)生立志除癌。 在此，我選用一則關(guān)于一名癌癥晚期病人運(yùn)用心理療法成功戰(zhàn)勝癌癥的故事，在于對(duì)不同層次的學(xué)生進(jìn)行多方面啟發(fā)教育，體現(xiàn)面向全體學(xué)生的課程理念。5．7 愉悅總結(jié)，及時(shí)反饋本節(jié)知識(shí)點(diǎn)零散，我將帶領(lǐng)學(xué)生回憶瀏覽本節(jié)內(nèi)容，使零散知識(shí)點(diǎn)系統(tǒng)化。在課堂反饋環(huán)節(jié)，我通過(guò)簡(jiǎn)單練習(xí)采用分組競(jìng)答的方式把握學(xué)生對(duì)知識(shí)的掌握程度，并給予表現(xiàn)突出的學(xué)生適當(dāng)獎(jiǎng)勵(lì)，這是本節(jié)課第三個(gè)亮點(diǎn)。競(jìng)答既使課堂顯得緊湊、集中，又有利于形成學(xué)生的競(jìng)爭(zhēng)意識(shí)，還使得學(xué)生的知識(shí)得以鞏固應(yīng)用。
人教版高中生物必修1細(xì)胞的衰老與凋亡說(shuō)課稿
4、最后從生物的壽命引入，探討細(xì)胞的死亡。強(qiáng)調(diào)細(xì)胞死亡有兩種形式。(1).細(xì)胞壞死，它是由某些外界因素造成細(xì)胞急速死亡，是一種被動(dòng)性死亡；(2).細(xì)胞凋亡，這是一種由特定基因控制的主動(dòng)性死亡。細(xì)胞壞死與細(xì)胞凋亡在形態(tài)學(xué)和生物化學(xué)上有著明顯的區(qū)別。細(xì)胞凋亡有廣泛的生物學(xué)意義，比如胚胎發(fā)育期手的發(fā)育如果沒(méi)有細(xì)胞的調(diào)亡就不會(huì)有纖細(xì)的手指；如果沒(méi)有正常的細(xì)胞調(diào)亡，蝌蚪的尾部就不會(huì)消失，它將永遠(yuǎn)不能變成青蛙……。正常的細(xì)胞調(diào)亡還肩負(fù)著維持各種組織器官固有體積和形態(tài)的功能；還會(huì)使機(jī)體內(nèi)異常的細(xì)胞得到及時(shí)清除，去處潛在的隱患；例如癌癥就是異常的細(xì)胞沒(méi)有及時(shí)死亡的結(jié)果……。因此細(xì)胞的正常死亡是生物體的一種非常重要的調(diào)節(jié)機(jī)制，是機(jī)體平衡細(xì)胞增殖，調(diào)節(jié)機(jī)體細(xì)胞樹(shù)木恒定的方式，是必不可少的生命過(guò)程。（15分鐘）5、課堂小結(jié)，可以把課堂傳授的知識(shí)盡快地轉(zhuǎn)化為學(xué)生的素質(zhì)；簡(jiǎn)單扼要的課堂小結(jié)，可使學(xué)生更深刻地理解政治理論在實(shí)際生活中的應(yīng)用，并且逐漸地培養(yǎng)學(xué)生具有良好的個(gè)性。

一、說(shuō)教材的地位和作用《細(xì)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?xì)胞中的元素和化合物》這一節(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(wú)機(jī)自然界中獲得的，沒(méi)有一種元素是細(xì)胞特有的。但細(xì)胞與非生物相比，各元素的含量又大不相同。說(shuō)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(duì)于學(xué)生了解生物的物質(zhì)性具有重要意義二、說(shuō)教學(xué)目標(biāo)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(jí)學(xué)生的認(rèn)知結(jié)構(gòu)及心理特征，我制定了以下的教學(xué)目標(biāo)：1、知識(shí)目標(biāo)：知道組成細(xì)胞的主要元素；知道為什么碳元素是構(gòu)成細(xì)胞的基本元素2、能力目標(biāo)：學(xué)會(huì)檢測(cè)生物組織中的糖類(lèi)、脂肪和蛋白質(zhì)的方法。（1）通過(guò)對(duì)C元素的分析，說(shuō)明有機(jī)化合物形成的可能性及必然性，初步培養(yǎng)學(xué)生跨學(xué)科綜合分析問(wèn)題的能力。（2）通過(guò)對(duì)組成細(xì)胞中的元素的百分比的分析，通過(guò)對(duì)不同化合物的質(zhì)量分?jǐn)?shù)的學(xué)習(xí)，培養(yǎng)學(xué)生理解、思考和分析問(wèn)題的能力。
人教版高中地理必修1第二章第四節(jié)全球氣候變化說(shuō)課稿
（一）教材的地位與作用本節(jié)教材包括三方面的內(nèi)容，（1）全球氣候在不斷變化之中。（2）全球氣候變化的可能影響。（3）氣候變化的適應(yīng)對(duì)策三方面說(shuō)明氣候變化及其對(duì)人類(lèi)活動(dòng)的影響。從標(biāo)準(zhǔn)的要求看，學(xué)習(xí)的重點(diǎn)不在全球氣候變化本身，而是把全球氣候變化看作是客觀存在的事實(shí)，從而探討全球氣候變化對(duì)地理環(huán)境及人類(lèi)活動(dòng)的影響。從資料中可以看出本節(jié)教學(xué)內(nèi)容涵蓋的時(shí)空跨度非常大，思維的鏈索很長(zhǎng)很廣，許多問(wèn)題涉及到學(xué)科的前沿及人類(lèi)所關(guān)注的熱點(diǎn)，因此，本節(jié)課對(duì)學(xué)生而言既有趣味性，又有挑戰(zhàn)性。 （二）教學(xué)目標(biāo)(1)知識(shí)與技能目標(biāo)：1.通過(guò)全球氣候的長(zhǎng)期演變圖，學(xué)生了解全球氣候處在波動(dòng)變化之中。2.通過(guò)資料認(rèn)識(shí)全球氣候一直處于變化之中并呈現(xiàn)一定變化周期，了解全球氣候變化對(duì)地理環(huán)境及人類(lèi)活動(dòng)的影響，能夠提出一些氣候變化的適應(yīng)對(duì)策。
人教版高中歷史必修3現(xiàn)代中國(guó)教育的發(fā)展說(shuō)課稿
一、教材分析下面我來(lái)談一談對(duì)教材的認(rèn)識(shí)：主要從教材的地位和作用、以及在此基礎(chǔ)上確立的教學(xué)目標(biāo)、教學(xué)重難點(diǎn)這三個(gè)方面來(lái)談。首先，來(lái)談教材的地位和作用：本課教材內(nèi)容主要從三個(gè)方面向?qū)W生介紹了現(xiàn)代中國(guó)教育的發(fā)展?fàn)顩r和趨勢(shì)：人民教育的奠基、動(dòng)亂中的教育和教育的復(fù)興，全面講述了新中國(guó)教育的三個(gè)階段。本課是文化史中中國(guó)史部分的最后一課， 也是必修三冊(cè)書(shū)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(shí)候曾經(jīng)說(shuō)過(guò)，“百年大計(jì)，教育為本。教育為本，在于育人”。教育是關(guān)系國(guó)計(jì)民生的大事。學(xué)生通過(guò)學(xué)習(xí)新中國(guó)教育發(fā)展的史實(shí)，理解“科教興國(guó)”、“國(guó)運(yùn)興衰，系于教育”的深刻含義。最終由此激發(fā)學(xué)生樹(shù)立“知識(shí)改變命運(yùn)、讀書(shū)成就人生”的信念，樹(shù)立勤奮學(xué)習(xí)、成人成才、報(bào)效祖國(guó)、服務(wù)社會(huì)的崇高理想。故本課的教學(xué)有極大的現(xiàn)實(shí)意義。談完了教材的地位和作用，我再分析一下教學(xué)目標(biāo)：
