人教版高中政治必修4社會發(fā)展的規(guī)律精品教案
四、學情分析本課的概念、原理很抽象，學生的認知能力及社會經(jīng)驗有限，應注意從以下幾個方面加以引導。1．澄清概念。本課涉及多個歷史唯物主義的基本概念，如社會存在、社會意識、生產(chǎn)方式、生產(chǎn)力、生產(chǎn)關系、經(jīng)濟基礎、上層建筑、革命、改革等。學生要準確深刻地掌握所學知識，首先就要對這些概念的內涵有比較明確的理解，因此，澄清概念既是學習本課的重要任務，也是學習本課的重要方法。2．觀察生活。在學習社會存在與社會意識的辯證關系原理時，學生可以從觀察自己身邊的生活入手，看看自己身邊各種意識現(xiàn)象背后的物質原因是什么。比如，民間流傳的神話、人們信仰的宗教、社會價值觀的變化等現(xiàn)象背后的物質原因是什么？同時，看看這些意識現(xiàn)象對人們行為和社會發(fā)展又有哪些能動的影響。

人教版高中地理必修2如何看待農民工現(xiàn)象精品教案
盡管如此，農民工作為一個新的社會階層，其獨特的經(jīng)濟需求和政治訴求應該得到充分的尊重。雖然農民工的“根”還在農村，但是他們已經(jīng)脫胎換骨，日益成長為一個迫切需要社會認可的新興階層。3.農民工處于何種生存境況？作為“廉價勞動力”，工資水平低，拖欠時有發(fā)生。作為“超時勞動力”，工作時間極長，超負荷從事繁重工作。作為“高危勞動力”，社會保障缺失，各種安全事故頻繁。4.農民工問題有多么重要？農民工問題關系到農業(yè)增效、農民增收和農村繁榮。農民工問題關系到工業(yè)化、城鎮(zhèn)化和“以工補農、以城促鄉(xiāng)”。農民工問題關系到社會主義和諧社會建設。5.解決農民工問題應該做些什么？構建城鄉(xiāng)一體化就業(yè)體系。健全農民工權益保障制度。強化農民工輸出地和輸入地培訓。穩(wěn)妥解決農民工戶籍問題。改進對農民工的管理和服務。
人教版高中地理必修2綠色食品知多少精品教案
生1：加強對綠色食品的宣傳和扶持力度。當前的形勢迫切要求我們發(fā)展綠色食品，因為綠色食品是真正實現(xiàn)可持續(xù)發(fā)展的，做到了發(fā)展經(jīng)濟和環(huán)境保護相結合，而且有利于增進人民身體健康。但目前綠色食品在市場上難成氣候，主要是宣傳和扶持不夠。生2：綠色食品對環(huán)境、生長過程、加工過程以及運輸?shù)冗^程都有很嚴格的要求，很多環(huán)境相對優(yōu)良的地區(qū)都是邊遠落后地區(qū)，必須給予政策上的扶持和優(yōu)惠，才能降低成本，市場發(fā)展前景才會更加廣闊?；顒优c探究對當?shù)鼐G色食品市場情況作調查并初步分析?；顒拥膶嵤┻^程：1．確定調查研究的目標并制定調查研究的計劃。市場調查要深入廣大消費者，可以去市場上做調查，‘對象包括消費者和經(jīng)營者。形式可以是問卷，也可以是現(xiàn)場采訪。弄清楚被調查者對綠色食品的態(tài)度，是否了解食用綠色食品的意義，是否懂得鑒別綠色食品等。對象力求涉及各個年齡段，多種職業(yè)。2．對問卷調查進行整理、分析，得出結論。
人教版高中地理必修2城市內部空間結構精品教案
過渡：在實際生活中，城市內部空間結構并非完全按照這一經(jīng)濟規(guī)律呈現(xiàn)，而是更具復雜性。這說明除了經(jīng)濟因素外，還有很多其他因素在起作用，請大家結合你的認識、圖2．9和案例1：紐約市的少數(shù)民族區(qū)談談你的看法。（2）其他因素I.收入 —— 形成不同級別住宅區(qū)的常見原因。有能力支付昂貴租金和選擇最佳居住環(huán)境的人，其居住地往往形成高級住宅區(qū)。II.知名度 ——城市內某些地區(qū)在歷史、文化或經(jīng)濟方面具有很高的聲譽，這往往會吸引更多新的住宅或商場建在該處，以提高其知名度。III.種族聚居區(qū)的形成 ——在有些城市的某一區(qū)域內，如果某個種族或宗教團體占優(yōu)勢，就可能形成種族聚居區(qū)。如紐約市的唐人街、哈林區(qū)、小意大利區(qū)等。IV歷史因素——城市的建筑物和街道設計可以維持久遠，早期的土地利用方式對日后的功能分區(qū)有著深遠的影響。3、城市內部空間結構的形成和變化
人教版高中地理必修2北京的自行車是多了還是少了精品教案
提問：城市環(huán)境污染源主要有哪些？有些同學基本同意自行車多是加劇南京空氣污染的間接原因，你同意他們的觀點嗎？在學生回答的基礎上，教師進行歸納小結：工業(yè)和交通是城市環(huán)境的主要污染源。而自行車是一種綠色交通工具，既環(huán)保又經(jīng)濟。只有當它在某些機動車和非機動車不分的地段，影響車輛行駛速度的時候，它才可能成為加劇空氣污染的間接原因。問：那我們針對交通工具對環(huán)境造成的影響，有什么解決方法嗎？歸納小結：? 實施減少汽車尾氣污染的技術措施? 加強道路綠化? 合理規(guī)劃城市道路，提高車速? 制定相關法規(guī)嚴禁各種車輛違規(guī)鳴喇叭? 在噪音嚴重的地區(qū)設置先進的隔音設施總結：通過前面的分析我們知道了自行車過多并不是造成北京交通擁擠的主要原因，但自行車多并且不遵守交通規(guī)則的確是造成交通擁堵的一個原因。從這方面來講，在一些混合車道地段，自行車是造成空氣污染加劇的間接原因。那么在北京到底是應該鼓勵自行車的發(fā)展還是限制自行車的發(fā)展呢？

(1)下面列出的是我國南北方傳統(tǒng)民居的差異，分析形成這些差異的自然原因：——北方民居正南正北的方位觀比南方強；——北方民居的墻體嚴實厚重，南方民居的墻體輕薄；——從北到南，民居的屋頂坡度逐漸增大，房檐逐漸加寬，房屋進深和高度逐漸加大。(2)下面列出的是我國南北方城市住宅摟的差異，分析導致這些差異的自然原因：——如果不考慮地價、建筑材料等因素，建同等面積的住房，北方的建筑成本比南方高 ；——建同樣高度的多幢樓房，北方樓房的南北間距比南方大。點撥：本活動要求學生了解由于地理環(huán)境的差異造成南北方建筑物特點的不同，并由此認識地理環(huán)境 差異對人們生活的影響。（1）比較而言，北方的冬季寒冷而漫長，南方的夏季濕熱而漫長。為了在冬季充分利用太陽光照和熱量，北方民居正南正北的方位觀比南方強。北方民居的墻體嚴實厚重，利用在冬季保溫御寒；南方民居的墻體輕薄，利于在夏季通風透氣。從北到南，年降水量逐漸增大，民居的屋頂坡度也逐漸增大（利于排水） ；隨著對保溫要求的降低和對通風納涼要求的提高，民居的屋檐逐漸加寬，房屋進深和高度逐漸加大。

人教版高中地理必修3第五章第二節(jié)產(chǎn)業(yè)轉移教案
1．閱讀圖5．16，說明產(chǎn)業(yè)向國外轉移對日本經(jīng)濟的不利影響。點撥：圖5．16直觀的顯示了產(chǎn)業(yè)轉移對日本經(jīng)濟的不利影響：形成“產(chǎn)業(yè)轉移出去的多，轉移進來的少→國內生產(chǎn)投資不足，生產(chǎn)困難→市場萎縮→產(chǎn)業(yè)向外轉移，外資不愿進入”的惡性循環(huán)。2．盡管重化工業(yè)的環(huán)境污染比較嚴重，但是卻能為工業(yè)化的發(fā)展提供堅實的基礎，因此成為發(fā)達工業(yè)的象征。日本、韓國的經(jīng)濟發(fā)展都經(jīng)歷了由輕工業(yè)(勞動密集型)到重化工業(yè)(資源密集型和資金密集型)到高科技工業(yè)(技術密集型)的階段。(1）為什么日本、韓國在重點發(fā)展重化工業(yè)之前，要先發(fā)展勞動密集型工業(yè)?點撥：重化工業(yè)的發(fā)展一方面需要有一定的工業(yè)基礎和技術工人，另一方面需要投入大量的資金，先發(fā)展勞動密集型工業(yè)有利于利用勞動力資源豐富且廉價的優(yōu)勢，積累資金和造就產(chǎn)業(yè)工人。所以，勞動力豐富的發(fā)展中國家或地區(qū)的工業(yè)化往往從優(yōu)先發(fā)展勞動密集型工業(yè)開始。
