人教版高中地理選修2百萬移民及其安置教案
三峽庫區(qū)農(nóng)村移民安置根本出路是通過發(fā)展大農(nóng)業(yè)來解決耕地不足，不應(yīng)盲目開墾荒坡地，防止產(chǎn)生新的水土流失，盡量避免生態(tài)環(huán)境惡化。2、就地后靠，就近安置模式三峽庫區(qū)淹沒區(qū)線狀分布的受淹特點(diǎn)有別于一般水庫淹沒區(qū)的片狀分布，使得庫區(qū)移民具有相對分散的特點(diǎn)，且淹沒涉及的356個(gè)鄉(xiāng)鎮(zhèn)沒有一個(gè)被全淹，甚至全淹的村也很少，這有利于移民在本縣甚至本鄉(xiāng)就近后靠安置，避免了水庫移民大量外遷、遠(yuǎn)遷所造成的種種困難和后遺癥。三峽移民搬遷大多可以就地后靠，就近安置，這是三峽移民的一大特色。就近后靠安置的優(yōu)點(diǎn)是不離本鄉(xiāng)本土，移民容易接受，且避免了移民大量外遷、遠(yuǎn)遷所造成的困難和后遺癥；缺點(diǎn)是容易對當(dāng)?shù)氐纳鷳B(tài)環(huán)境造成過大的壓力，如過度開墾坡地、破壞植被、加劇水土流失等。3、工程周期長，可從容安置移民三峽工程建設(shè)周期長（1994年～2009年，共17年），使得移民安置能夠及早進(jìn)行，可以從容安置移民的生產(chǎn)和生活。

教學(xué)目標(biāo)1、明確扇形統(tǒng)計(jì)圖的制作步驟，能夠根據(jù)相關(guān)數(shù)據(jù)較為準(zhǔn)確地制作扇形統(tǒng)計(jì)圖．2、進(jìn)一步理解扇形統(tǒng)計(jì)圖的特點(diǎn)，建立百分比大小和扇形圓心角大小之間初步的直觀敏感度．3、能夠?qū)崿F(xiàn)不同統(tǒng)計(jì)圖數(shù)據(jù)間的合理轉(zhuǎn)換，再次體會(huì)幾種統(tǒng)計(jì)圖的不同特點(diǎn)，為合理選擇統(tǒng)計(jì)圖表示數(shù)據(jù)打下一定的基礎(chǔ)．4、通過實(shí)例，理解三種統(tǒng)計(jì)圖的特點(diǎn)，能根據(jù)具體問題選擇合適的統(tǒng)計(jì)圖清晰、有效地描述數(shù)據(jù)．5、在統(tǒng)計(jì)活動(dòng)的過程中，通過相互間的合作與交流，掌握畫統(tǒng)計(jì)圖和選擇統(tǒng)計(jì)圖的方法；經(jīng)歷數(shù)據(jù)的收集、整理和簡單分析、作出決策的統(tǒng)計(jì)活動(dòng)過程，發(fā)展統(tǒng)計(jì)觀念．6、通過對現(xiàn)實(shí)生活中的數(shù)據(jù)分析，感受數(shù)學(xué)與現(xiàn)實(shí)生活的密切聯(lián)系，說出統(tǒng)計(jì)圖在現(xiàn)實(shí)生活中的應(yīng)用，提高學(xué)習(xí)數(shù)學(xué)興趣．
學(xué)做家常菜教學(xué)設(shè)計(jì)教案
小學(xué)五年級(jí)的學(xué)生應(yīng)該具備一些生活技能， 學(xué)做家常菜是我們生活的必需，是每個(gè)，人都應(yīng)該掌握的生存技能。本主題的目的通過學(xué)習(xí)做簡單的家常菜，引領(lǐng)小學(xué)生走進(jìn)家務(wù)勞動(dòng)，鍛煉生活的自理能力和提高適應(yīng)生活的能力，體會(huì)生活和學(xué)習(xí)的樂趣，激發(fā)學(xué)生將學(xué)校學(xué)習(xí)和家務(wù)勞動(dòng)密切結(jié)合起來，形成積極的生活和學(xué)習(xí)的態(tài)度。本主題安排了“問題與思考”“學(xué)習(xí)與探究”“實(shí)踐與體驗(yàn)”總結(jié)與交流“拓展與創(chuàng)新”五個(gè)環(huán)節(jié)，從提出問題開始，到探究與體驗(yàn)，最后到學(xué)有所用，循序漸進(jìn)，引導(dǎo)學(xué)習(xí)走進(jìn)中式餐飲文化，學(xué)做日常生活中的家常菜，掌握勞動(dòng)的技能和方法，體驗(yàn)做家務(wù)勞動(dòng)帶來的快樂和享受，激發(fā)學(xué)生對家常菜的探究與實(shí)踐的興趣，逐步掌握日常生活所需的基本技能，培養(yǎng)熱愛勞動(dòng)、熱愛生活的意識(shí)。
認(rèn)識(shí)三角形教案教學(xué)設(shè)計(jì)
四個(gè)同學(xué)為一個(gè)合作小組；每個(gè)小組利用教師為其準(zhǔn)備的各類三角形，作出它們的高．比一比，看哪一個(gè)小組做得最快，發(fā)現(xiàn)的結(jié)論多． 師生行為：學(xué)生操作、討論，教師巡視、指導(dǎo)，使學(xué)生理解【設(shè)計(jì)意圖】通過讓學(xué)生操作、觀察、推理、交流等活動(dòng)，來培養(yǎng)學(xué)生的動(dòng)手、動(dòng)腦能力，發(fā)展其空間觀察．活動(dòng)結(jié)論：1．銳角三角形的三條高都在三角形內(nèi)； 2．直角三角形的一條高在三角形內(nèi)（即斜邊上的高），而另兩條高恰是它的兩條直角邊； 3．鈍角三角形的一條高在三角形內(nèi)，而另兩條高在三角形外．（這是難點(diǎn)，需多加說明） 總之：任何三角形都有三條高，且三條高所在的直線相交于一點(diǎn)．（我們把這一點(diǎn)叫垂心）課堂小結(jié) 1．三角形中三條重要線段：三角形的高、中線和角平分線的概念． 2．學(xué)會(huì)畫三角形的高、中線和角平分線．
