人教版高中政治必修1第二課多變的價格教案
（四）反思總結(jié)，當堂檢測。本節(jié)內(nèi)容講述了價格變動對人們生活、生產(chǎn)的影響作用，主要知識框架如下：（1）、價格變動會影響人們的消費需求，商品價格上漲，人需求就減少，反之，則增大。價格變動對不同商品需求影響程度是不一樣的，對生活必需品的需求量影響較小，對高檔耐用品的需求量影響較大。相關(guān)商品價格變動對消費需求的影響不同，某種商品價格上漲，就會減少需求量，其替代品需求量增加，其互補品需求量則減少。（2）、價格變化也會影響生產(chǎn)經(jīng)營，價格變動會調(diào)節(jié)生產(chǎn)，刺激生產(chǎn)者改進技術(shù)，提高勞動生產(chǎn)率，促使生產(chǎn)者生產(chǎn)適銷對路的高 質(zhì)量產(chǎn)品。（五）發(fā)導(dǎo)學案、布置預(yù)習。預(yù)習第三課第一框《消費及其類型》，完成預(yù)習導(dǎo)學案練習題九、板書設(shè)計《價格變動的影響》1、對人們生活的影響（1）商品價格變動與消費需求量之間的關(guān)系（2）不同商品的需求量對價格變動的反應(yīng)程度不同

二、做理智的消費者1、量入為出，適度消費2、避免盲從，理性消費3、保護環(huán)境，綠色消費4、勤儉節(jié)約，艱苦奮斗十、教學反思本課的設(shè)計采用了課前下發(fā)預(yù)習學案，學生預(yù)習本節(jié)內(nèi)容，找出自己迷惑的地方。課堂上師生主要解決重點、難點、疑點、考點、探究點以及學生學習過程中易忘、易混點等，最后進行當堂檢測，課后進行延伸拓展，以達到提高課堂效率的目的。這節(jié)課我們主要學習了影響人們消費的幾種消費心理和幾種科學的消費觀。本節(jié)課與學生生活十分貼近所以這節(jié)課充分的調(diào)動了學生學習的興趣和積極性，并且讓學生針對案例進行充分的分組討論分析，通過學生的展示分析和補充可以知道學生們不但深層次分析了教學原理也透徹理解了教學重難點大大提高了課堂效率.。通過案例的分析進一步領(lǐng)會了教材原理突破了本節(jié)課的難點——樹立正確的消費觀。整堂課學生求知旺盛，復(fù)雜的知識變得簡單化，從閱讀教材到獨立思考分析再到合作討論最后的展示質(zhì)疑答疑，加深了印象，提高了能力。
人教版高中政治必修1第一課神奇的貨幣教案
1、外匯與外幣的關(guān)系：（1）外匯包括外幣，但外匯不等于就是外幣。外幣是指外國的貨幣，包括外國的紙幣、鑄幣；外匯通常是以外國貨幣表示的用于國際間結(jié)算的支付手段，具體包括外幣、外幣有價證券、外幣支付憑證等。（2）外幣屬于外匯的范圍，但不能把二者等同起來。通常情況下，只有可以自由兌換的外幣才是外匯，因為外匯的實質(zhì)是國際支付手段，如果某種貨幣不能自由兌換，它就不能成為國際支付手段。外匯執(zhí)行的 主要是貨幣的支付手段的職能。（3）持有外匯意味著對外匯發(fā)行國擁有債權(quán)。持有外匯過多，一方面意味著國際支付能力強和有可能對外匯發(fā)行國施加影響；另一方面則意味著大量該由本國享受的資源，被借給外國利用，并要承擔外匯貶值的風險。2、關(guān)于幣值變化的分析：（1）對貨幣升值的具體分析：一個國家的貨幣升值（上?。┖?，同量的這種貨幣能比以前換 取更多的他國貨幣，買到更多的他國商品。

人教版高中地理必修3地理信息技術(shù)在區(qū)域地理環(huán)境研究中的應(yīng)用說課稿
通過列表對比法、歸納法、、多媒體輔助法等教學方法，突破理論性強、不宜理解的“3S”原理與區(qū)別的知識難點。學生更是學會運用圖表方法、高效記憶法、合作學習法等方法學習地理知識，增加學習能力。[幻燈片] “3S技術(shù)”的應(yīng)用：地理信息技術(shù)的應(yīng)用十分廣泛，從實際身旁的社會生產(chǎn)生活，到地理學的區(qū)域地理環(huán)境研究。學生的年齡和認知范圍決定，此部分的案例教學的運用，前者容易接觸到、簡單直觀、易區(qū)分掌握“3S”技術(shù)特點和具體應(yīng)用。而后者涉及地理學科的綜合性和區(qū)域性的特點，難度較大。針對學情特點，我多以前者案例入手學習，以后者案例加以補充。案例：遙感：（1）視頻 專家解說衛(wèi)星遙感受災(zāi)影象（2）教材 圖1.6 1998年8月28日洞庭湖及荊江地區(qū)衛(wèi)星遙感圖像（3）視頻 2008年5月13日“北京一號”衛(wèi)星提供汶川的災(zāi)區(qū)遙感圖像（4）教材 閱讀 遙感在農(nóng)業(yè)方面的應(yīng)用
人教版高中地理必修3森林的開發(fā)和保護—以亞馬孫熱帶雨林為例說課稿
【這部分的設(shè)計目的，要學生明白熱帶雨林只是一個案例，我們的目的是要合理開發(fā)和保護全世界的森林。由森林的開發(fā)與保護來明確區(qū)域發(fā)展過程中產(chǎn)生的環(huán)境問題，危害及治理保護措施?！咳缓笾R遷移——東北林區(qū)的開發(fā)與保護介紹東北地區(qū)的森林材料：東北林區(qū)是我國最大的天然林區(qū)，主要分布于大、小興安嶺及長白山地，在平衡大氣成分、凈化空氣、補給土壤有機質(zhì)、涵養(yǎng)水源、保持水土、改善地方氣候有重要的作用。它還是我國最大的采伐基地，宜林地區(qū)廣，森林樹種豐富。 東北林區(qū)開發(fā)中的問題及影響點撥：由于人類的嚴重超采，采育脫節(jié)，亂砍濫伐，毀林開荒，再加上森林火災(zāi)，東北林區(qū)的面積在銳減，帶來了嚴重的生態(tài)惡化。我們該如何開發(fā)和保護東北地區(qū)的森林呢？
人教版高中地理必修3區(qū)域農(nóng)業(yè)可持續(xù)發(fā)展—以我國東北地區(qū)為例說課稿
（3）師生討論，提升思維深度。教師引領(lǐng)學生將討論由農(nóng)業(yè)生態(tài)破壞、土地利用不合理等表象問題逐步深入到農(nóng)業(yè)結(jié)構(gòu)不合理、農(nóng)業(yè)技術(shù)落后等深層問題，提升了學生思維的深度。（4）角色體驗，突破難點落實重點。在農(nóng)民與保護區(qū)工作人員的角色體驗活動中，學生們嘗試換位思考，在沖突與交鋒中，在教師的引領(lǐng)下，重新認識環(huán)境保護與區(qū)域經(jīng)濟發(fā)展的關(guān)系，在情感體驗中加深對可持續(xù)發(fā)展內(nèi)涵的理解，小沖突凸顯大矛盾是本課設(shè)計的創(chuàng)新之處。2．注重對地理問題的探究，突出地理學科本質(zhì)。地理學科具有綜合性、區(qū)域性特征，區(qū)域差異及人地和諧發(fā)展觀是我們在教學中應(yīng)該把握的基本特征，也是我們應(yīng)當把握的地理學科的本質(zhì)特征，因此在本節(jié)課的設(shè)計中我注重抓住地理事物的空間特征、綜合性特征，以突出地理學科的本質(zhì)。
人教版高中地理必修3區(qū)域工業(yè)化與城市化—以我國珠江三角洲地區(qū)為例說課稿
A.城鎮(zhèn)數(shù)量猛增B.城市規(guī)模不斷擴大【設(shè)計意圖】通過讀圖的對比分析，提高學生提取信息以及對比分析問題的能力，通過小組之間的討論，培養(yǎng)合作能力。五、課堂小結(jié)和布置作業(yè)關(guān)于課堂小結(jié)，我打算讓學生自己來總結(jié)，你這節(jié)課學到了什么。這樣既可以提高學生的總結(jié)概括能力，也可以讓我在第一時間內(nèi)獲得它們的學習反饋。(本節(jié)課主要學習了珠三角的位置和范圍以及改革開放以來珠三角地區(qū)工業(yè)化和城市化的發(fā)展。)關(guān)于作業(yè)的布置，我打算采用分層次布置作業(yè)法。第一個層次的作業(yè)是基礎(chǔ)作業(yè)，要求每一位同學都掌握，第二個層次的作業(yè)是彈性作業(yè)，學生可以根據(jù)自己的情況來選做。整個這堂課，老師只是作為一個引導(dǎo)者、組織者的角色，學生才是課堂上真正的主人，是自我意義的建構(gòu)者和知識的生成者，被動的、復(fù)制式的課堂將離我們遠去。
人教版高中地理必修3資源的跨區(qū)域調(diào)配—以我國的西氣東輸為例說課稿
由于這部分知識已要求學生在課前收集相關(guān)資料探討分析，，現(xiàn)在提供機會讓他們進行交流，充分發(fā)表各自的見解。所以，學生對這個知識掌握起來并不難。所以，我對這部分內(nèi)容不做太多的講解，只要做進一步的梳理，加深學生的理解即可。 第三是小結(jié)環(huán)節(jié) 在學生對西氣東輸工程的原因掌握之后進入的是小結(jié)環(huán)節(jié)，這里我進一步提出問題：在西氣東輸工程段的建設(shè)中有沒有什么難關(guān)？ 通過西氣東輸?shù)碾y度了解，間接的表現(xiàn)我國的科技的發(fā)展，增加學生的愛國情，同時也說明西氣東輸?shù)慕ǔ梢灿屑夹g(shù)這一原因。從而也完成了本課時的小結(jié)。 第四環(huán)節(jié)是作業(yè)布置 在這里要求學生課后預(yù)習本課剩下的內(nèi)容：思考西氣東輸對區(qū)域發(fā)展的影響以及為何要實施資源的跨區(qū)域調(diào)配。通過這樣的問題一方面為下節(jié)課學習奠定基礎(chǔ)，另一方面體現(xiàn)本課學習從“個”到“類”從特殊到一般的過程。

2、確立教育優(yōu)先發(fā)展地位，提出“科教興國”戰(zhàn)略：①提出“三個面向”指導(dǎo)方針；（即教育要面向現(xiàn)代化，面向世界，面向未來）1983年，當我們國家的改革開放處在起步階段時，鄧小平同志以歷史的眼光，從戰(zhàn)略的高度，為北京景山學校題詞：“教育要面向現(xiàn)代化，面向世界，面向未來?！倍嗄陙?，這“三個面向”的題詞所蘊含的深刻的教育理念，已經(jīng)成為中國教育改革與發(fā)展的指針，“三個面向”的思想，已經(jīng)深入人心；成為我們教育改革的旗幟和靈魂。②改革教育制度，基礎(chǔ)、中等和高等教育全面發(fā)展；基礎(chǔ)教育——普及九年義務(wù)教育，制定《義務(wù)教育法》（2006年）中等教育——實行普通教育與職業(yè)教育并舉；高等教育——增設(shè)邊緣學科，建立學位制，擴大自主權(quán)③實施發(fā)展高等教育的“211工程”計劃；211工程"就是面向21世紀，重點建設(shè)100所左右的高等學校和一批重點學科點。
