人教版高中地理必修1第四章第二節(jié)山岳的形成說課稿
（一）教材的地位與作用第一部分的內(nèi)容——山岳的形成，教材首先指出山岳的形成和內(nèi)力作用關(guān)系密切，然后對褶皺山、斷塊山和火山的成因、基本形態(tài)特征和規(guī)模進(jìn)行分析。由于褶皺山和斷塊山是形成于一定的地質(zhì)構(gòu)造上的，所以教材在講述這兩種山岳的形成時，都先從褶皺和斷層這兩種最基本的地質(zhì)構(gòu)造開始講起，并且教材還配以閱讀材料和活動題來幫助學(xué)生更好地掌握這部分內(nèi)容。第二部分的內(nèi)容——山岳對交通的影響，教材主要分析了山岳對交通三方面的影響：對運(yùn)輸線路結(jié)構(gòu)、對線路分布格局和線路延伸方向的影響，并且設(shè)計了相應(yīng)的活動題幫助學(xué)生理解。（二）教學(xué)目標(biāo)(1)知識與技能目標(biāo)：1．了解褶皺的概念和基本形態(tài)，掌握正確判斷背斜和向斜的方法，理解褶皺山的概念。2．了解斷層的概念，掌握斷層對地表形態(tài)的影響，理解斷塊山的概念。3．了解火山的形成過程，掌握火山的組成。

4、【自主探究】巴山夜雨的成因③材料三：三國時期，諸葛亮于農(nóng)歷6月的一天，在葫蘆峪設(shè)下伏兵，打算用火攻全殲司馬懿。這一天，晴空萬里暑熱難耐，真乃火攻之良機(jī)。諸葛亮依計將司馬懿之眾誘入谷中……然而，正當(dāng)大火沖天，司馬懿全軍行將覆滅之時，一場大雨不期而至，大雨澆滅了諸葛亮扶漢反魏的壯志，使他喊出了“謀事在人，成事在天，不可強(qiáng)也”的千古悲歌。【設(shè)計理念】前后呼應(yīng)，發(fā)散思維。通過自主探究，學(xué)生各抒己見，完成對熱力環(huán)流整個知識框架的一個總結(jié)，既考查了學(xué)生的課堂學(xué)習(xí)效果，又鍛煉了學(xué)生知識的遷移能力，并認(rèn)識生活中的地理規(guī)律，用生動的語言拉近學(xué)生與大氣理性知識的距離，體會到地理學(xué)科的重要性。【提問】如果將白天換成夏季，將夜間換成冬季，情況又會怎樣？城市與郊區(qū)之間也存在著熱力環(huán)流——城市風(fēng)，它們是怎樣形成的？了解城市風(fēng)的出現(xiàn)有何重要意義？如果地球上在赤道和兩極之間存在熱力環(huán)流，這個熱力環(huán)流應(yīng)該怎樣？這幾個問題，請大家課后慢慢思考。
人教版高中地理必修1第二章第三節(jié)常見的天氣系統(tǒng)說課稿
一、說教材（一）教材的地位與作用本節(jié)內(nèi)容是本單元知識結(jié)構(gòu)中重要的一環(huán)，具有承上啟下的作用。由于各種天氣現(xiàn)象的產(chǎn)生與大氣的熱力狀況、大氣的運(yùn)動有密切的聯(lián)系，所以，本課是在綜合前兩節(jié)內(nèi)容的基礎(chǔ)上，闡述常見的天氣現(xiàn)象的成因。在實(shí)際生活中，天氣系統(tǒng)與人們的生產(chǎn)、生活密切相關(guān)。本課所講的內(nèi)容對于學(xué)生了解天氣變化的最基本因素，普及天氣預(yù)報知識具有積極的意義。（二）教學(xué)目標(biāo)(1)知識與技能目標(biāo)：⑴從圖片和簡易圖中，知道氣團(tuán)（冷氣團(tuán)、暖氣團(tuán)）的概念；鋒的概念與分類；低壓（氣旋）、高壓（反氣旋）、高壓脊、低壓槽的概念。 ⑵從氣溫、氣壓、濕度、降水、風(fēng)等幾方面分析各種天氣系統(tǒng)的形成及其氣流特點(diǎn)，并綜合出各種天氣系統(tǒng)控制下的天氣狀況。⑶知道低壓槽和高壓脊概念及在圖上的表示方法。(2)過程與方法目標(biāo)：⑴讓學(xué)生能閱讀和簡單分析天氣圖，解釋天氣變化現(xiàn)象；⑵用案例說明氣象災(zāi)害發(fā)生的原因和危害；
人教版高中地理必修1第一章第二節(jié)太陽對地球的影響說課稿
（一）教材的地位與作用本節(jié)主要闡述太陽輻射和太陽活動對地球的影響。太陽輻射對地球的影響主要是從太陽為地球提供能量這個方面來闡述，通過圖片的形式從四個方面來分析。不應(yīng)讓學(xué)生記憶這四個方面，需要?dú)w納為：（1）直接或間接（化石燃料）為地球提供大部分能量。（2）維持四大圈層物質(zhì)循環(huán)和能量交換，決定地理環(huán)境的基本特征。（二）教學(xué)目標(biāo)(1)知識與技能目標(biāo)：1.闡述太陽對地球的影響。太陽對地球的影響，包括太陽輻射對地球的影響和太陽活動對地球的影響。2.太陽輻射的概念、來源、波長等只作一般了解；太陽活動對地球影像是通過作用氣候、地球電離層和磁場而發(fā)生的，主要包括磁暴、無線電短波通訊被干擾、極光和氣候異常等。3.教材涉及太陽活動的概念、標(biāo)志和周期需要明確，而太陽大氣分層及對應(yīng)太陽活動現(xiàn)象只作一般了解。
人教版高中地理必修1第二章第四節(jié)全球氣候變化說課稿
（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)對策三方面說明氣候變化及其對人類活動的影響。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地理環(huán)境及人類活動的影響。從資料中可以看出本節(jié)教學(xué)內(nèi)容涵蓋的時空跨度非常大，思維的鏈索很長很廣，許多問題涉及到學(xué)科的前沿及人類所關(guān)注的熱點(diǎn)，因此，本節(jié)課對學(xué)生而言既有趣味性，又有挑戰(zhàn)性。 （二）教學(xué)目標(biāo)(1)知識與技能目標(biāo)：1.通過全球氣候的長期演變圖，學(xué)生了解全球氣候處在波動變化之中。2.通過資料認(rèn)識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地理環(huán)境及人類活動的影響，能夠提出一些氣候變化的適應(yīng)對策。
人教版高中地理必修2第二章第一節(jié)城市內(nèi)部空間結(jié)構(gòu)說課稿
提問：結(jié)合課本找出城市地域結(jié)構(gòu)模式的類型及各自特點(diǎn)，模式形成的因素又有哪些？學(xué)生回答，使其掌握基本模式及特點(diǎn)，通過對比，分析把握每一模式各自的特征，學(xué)會把握事物本質(zhì)。◆設(shè)計意圖：閱讀課本，總結(jié)歸納，同時引導(dǎo)，通過原因規(guī)律的探究，大膽設(shè)想，總結(jié)規(guī)律掌握人文地理學(xué)習(xí)思路。4.活動設(shè)計：內(nèi)部空間結(jié)構(gòu)變化，結(jié)合實(shí)例，分析說明。提問：結(jié)合江寧區(qū)的變化，分析江寧區(qū)城市結(jié)構(gòu)發(fā)生了哪些變化？結(jié)合課本24頁活動題，提出功能結(jié)構(gòu)布局方案？通過理論聯(lián)系實(shí)際，讓學(xué)生更好理解理論，掌握城市結(jié)構(gòu)布局的變化及其影響因素，通過活動題方案的提出，學(xué)生能夠掌握布局的規(guī)律性，解決問題。設(shè)計意圖：理論聯(lián)系實(shí)際，知識的不枯燥性，提高學(xué)生學(xué)習(xí)興趣。同時，能夠通過總結(jié)，深層次認(rèn)識城市結(jié)構(gòu)布局，活學(xué)活用。
人教版高中地理必修2第四章第二節(jié)工業(yè)地域的形成說課稿
下面要針對工業(yè)地域內(nèi)部的工業(yè)聯(lián)系進(jìn)行講解，這里主要涉及到的是工序上的工業(yè)聯(lián)系。在這段文字的處理上，我會將鋼鐵、石化、機(jī)械加工等工業(yè)部門分散成一步一步的工序，便于學(xué)生理解這種工業(yè)上的聯(lián)系方式與構(gòu)造，進(jìn)而對于工業(yè)的發(fā)育程度這一概念的理解也就相對簡單了。緊接著需要講述的是工業(yè)分散的內(nèi)容。工業(yè)分散是建立在現(xiàn)代的交通運(yùn)輸方式和通信技術(shù)與手段上的。它主要針對的是體積小、重量輕、價格昂貴的電子產(chǎn)品生產(chǎn)領(lǐng)域，目的是根據(jù)原件的不同性質(zhì)選擇不同的生產(chǎn)地域，利用其各異的優(yōu)勢條件以節(jié)省開支。由于案例都是針對高科技產(chǎn)品的生產(chǎn)而提出的，因此在這段教材的教學(xué)中我會注意避免將工業(yè)分散這一現(xiàn)象描述得更為高級。要讓學(xué)生明白，無論是工業(yè)集聚還是工業(yè)分散，它們之間是沒有好壞之分的。最后將進(jìn)行課堂小結(jié)，由于本節(jié)內(nèi)容較少且相對簡單，可以在最后適當(dāng)添加部分練習(xí)題，重點(diǎn)考察一二兩節(jié)的相關(guān)知識點(diǎn)。
