人教版高中政治必修3傳統(tǒng)文化的繼承說課稿
只有對儒家的價值作出客觀、公正、全面的評價，才可能避免陷入文化虛無主義或文化復(fù)古主義的誤區(qū)，合理地、充分地開發(fā)利用儒學(xué)乃至整個國學(xué)的資源為現(xiàn)代社會服務(wù)，為促進(jìn)我國經(jīng)濟(jì)發(fā)展服務(wù)。運(yùn)用所學(xué)知識，談?wù)剬Υ鍖W(xué)我們應(yīng)該持有的態(tài)度。答案：（1）儒學(xué)是我國傳統(tǒng)文化中一個非常重要的組成部分。傳統(tǒng)文化具有相對穩(wěn)定性，它的內(nèi)涵又能夠因時而變，因此，我們對待儒學(xué)的正確態(tài)度應(yīng)該是“取其精華，去其糟粕，批判繼承，古為今用”。（2）面對儒學(xué)，我們要辯證地認(rèn)識它在現(xiàn)實(shí)生活中的作用，分辨其中的精華和糟粕。對于其中符合社會發(fā)展要求的、積極向上的內(nèi)容，應(yīng)該繼續(xù)保持和發(fā)揚(yáng)，使其為社會主義現(xiàn)代化建設(shè)服務(wù)；對于其中不符合社會發(fā)展要求的、落后的、腐朽的東西，必須“移風(fēng)易俗”，自覺地加以改造和剔除。(五)作業(yè)布置傳統(tǒng)文化的作用是什么？如何正確對待傳統(tǒng)文化？

（2）世界觀，人生觀，價值觀是人們文化素養(yǎng)的核心和標(biāo)志。一旦形成就會對人產(chǎn)生深遠(yuǎn)持久的影響。（但隨著生活閱歷的變化，人們文化素養(yǎng)的提高，人們的“三觀”會發(fā)生變化。）總之“潛移默化”指每時每刻，不知不覺；是從文化對人影響的過程來看的?！吧钸h(yuǎn)持久”指經(jīng)年累月，難以抹去；是從文化對人影響的結(jié)果上說的。3.課堂總結(jié)：首先啟動學(xué)生思維，教會學(xué)生把握知識主線，建構(gòu)知識體系，先由學(xué)生進(jìn)行總結(jié)，然后教師進(jìn)行必要的補(bǔ)充4、布置作業(yè)：布置作業(yè)。運(yùn)用文化對人的影響的知識分析“近朱者赤，近墨者黑”，并且應(yīng)該如何處理朋友之間的關(guān)系。設(shè)計(jì)這個作業(yè)的意圖是既讓學(xué)生靈活運(yùn)用所學(xué)知識，同時又讓學(xué)生回歸生活，如何處理朋友之間的關(guān)系。5、板書設(shè)計(jì)遵循板書設(shè)計(jì)的實(shí)用性、直觀性的原則，根據(jù)本課的教材特點(diǎn)，我采用結(jié)構(gòu)式板書，這樣設(shè)計(jì)比較直觀、系統(tǒng)，以便于學(xué)生能夠系統(tǒng)把握和理解知識。
人教版高中政治必修3聚焦文化競爭力說課稿
（1）文化與經(jīng)濟(jì)、政治在經(jīng)濟(jì)基礎(chǔ)上相互影響。①經(jīng)濟(jì)、政治和文化是社會生活的三個基本領(lǐng)域。其中，經(jīng)濟(jì)是基礎(chǔ)，政治是經(jīng)濟(jì)的集中表現(xiàn)，文化是經(jīng)濟(jì)和政治的反映。一定的文化由一定的經(jīng)濟(jì)、政治所決定，又反作用于一定的政治、經(jīng)濟(jì)，給予政治、經(jīng)濟(jì)以重大影響。②經(jīng)濟(jì)發(fā)展是文化發(fā)展的基礎(chǔ)。但這并不意味著文化的發(fā)展始終與經(jīng)濟(jì)的發(fā)展亦步亦趨。如同不能簡單地把精神文明看作是物質(zhì)文明的派生物和附屬品一樣，也不能簡單地認(rèn)為文化是經(jīng)濟(jì)、政治的派生物和附屬品。文化有其自身的傳承性和相對的獨(dú)立性。那種認(rèn)為只要物質(zhì)條件好了，精神文化自然而然地就會好起來，物質(zhì)條件差一點(diǎn)，精神文化就不可能搞好的觀點(diǎn)，不符合歷史發(fā)展的事實(shí)，是不正確的。③掀開歷史的畫卷，文化既有古今和地域之別，又有先進(jìn)與落后、腐朽之分。不同的文化，對經(jīng)濟(jì)、政治的影響不同，對社會發(fā)展的作用也不同。不同民族的文化，影響不同民族和國家各具特色的發(fā)展道路。

（二）講授新課：1、講授重點(diǎn)：文化與經(jīng)濟(jì)、政治的關(guān)系。我首先帶領(lǐng)學(xué)生分析課本上的活動探究，了解日常生活中的常見活動，讓學(xué)生們觀看視頻材料幫助學(xué)生對文化活動、經(jīng)濟(jì)活動、政治活動進(jìn)行辨別和分類。然后讓學(xué)生們舉例說明，綜合探究，最后通過集體討論得出文化與經(jīng)濟(jì)政治的關(guān)系：經(jīng)濟(jì)是基礎(chǔ)，政治是經(jīng)濟(jì)的集中表現(xiàn)，文化是經(jīng)濟(jì)和政治的反映，一定的文化由一定的經(jīng)濟(jì)和政治決定，又反作用于政治和經(jīng)濟(jì)。這個問題是本課重點(diǎn)。要引導(dǎo)學(xué)生循序漸進(jìn)，集體討論，得出結(jié)論。2、突破難點(diǎn)：（1）文化與經(jīng)濟(jì)政治相互交融，在時代發(fā)展的進(jìn)程中。首先播放上海世博會視頻，讓學(xué)生體會文化、經(jīng)濟(jì)、政治活動，另外我會引導(dǎo)學(xué)生積極舉生活中的事例，來說明問題，讓學(xué)生學(xué)會舉一反三，充分理解這一知識，讓學(xué)生明白文化與經(jīng)濟(jì)、政治的聯(lián)系，讓學(xué)生清楚文化滲透的力量有多大，幫助學(xué)生樹立反對文化霸權(quán)主義的意識。

（二）引入內(nèi)容1、播放幻燈片，從名言引出思考，什么是文化，如何理解文化？學(xué)生探究，既可質(zhì)疑，也可談自己對文化的理解2、幻燈片，以三組幻燈，分三個階段，學(xué)生分別通過小組討論的形式，歸納總結(jié)文化現(xiàn)象的三個特征3、根據(jù)對文化現(xiàn)象的認(rèn)識，歸納總結(jié)文化的內(nèi)涵及外延小活動：把不是文化的山、水、樹，由幾組同學(xué)畫出來，體會文化的含義4、一組判斷題，哪些是文化的，哪些不是5、理解文化的特點(diǎn)首先，根據(jù)前面，總結(jié)文化現(xiàn)象的特征，歸納出文化的普通性及特殊性其次，播放視頻，歸納總結(jié)文化是人類特有的現(xiàn)象第三，根據(jù)教材材料，小組探究總結(jié)，文化是后天習(xí)得的第四，借助小活動的材料，歸納，文化需要一定的物質(zhì)載體6、文化的作用首先、觀看視頻，小組探究總結(jié)，文化對于人的影響其次，觀看視頻，小組探究總結(jié)，文化對社會的影響
人教版高中政治必修3文化創(chuàng)新的途徑說課稿
一、 教材分析1、地位和作用《文化創(chuàng)新的途徑》是人教版教材高二政治必修3第二單元第五課第二個框題內(nèi)容，本課是對全面兩課的一個提升，同時對接下來學(xué)習(xí)第三、四單元的知識具有指導(dǎo)作用。文化創(chuàng)新是一個社會熱點(diǎn)，具有很強(qiáng)的思想理論性和探索實(shí)踐性。在前面兩課中，學(xué)生基本明確了文化的交流、傳播和發(fā)展；也明白了文化的繼承和發(fā)展需要創(chuàng)新。而怎樣進(jìn)行創(chuàng)新是本節(jié)課探討的內(nèi)容，也是本單元的重點(diǎn)、難點(diǎn)和落腳點(diǎn)。2、教學(xué)目標(biāo)（1）知識與能力目標(biāo)：①識計(jì)文化創(chuàng)新的途徑；理解文化創(chuàng)新過程中要認(rèn)識和處理好兩對基本關(guān)系：當(dāng)代文化與傳統(tǒng)文化、民族文化和外來文化的關(guān)系；②使學(xué)生初步具備認(rèn)識和處理當(dāng)代文化與傳統(tǒng)文化、民族文化與外來文化關(guān)系的能力；使學(xué)生具備在合作、探究中體驗(yàn)生活、生成認(rèn)識、構(gòu)建知識的能力。

3、文化的力量。為了使學(xué)生能辨證地分析文化的力量，我設(shè)計(jì)了兩個問題進(jìn)行探討：（1）是不是任何文化都能起促進(jìn)作用？（2）你在聽或唱國歌時感受到一種什么樣的力量？這樣，學(xué)生在對比中學(xué)會辨證地分析文化的力量——先進(jìn)的、健康的文化能促進(jìn)社會發(fā)展和個人成長；落后的、腐朽的文化則阻礙社會發(fā)展和個人成長。同時還能提高學(xué)生的文化賞析能力，從而引導(dǎo)學(xué)生裝自覺參加健康有益的文化活動，抵制不良文化的影響，投身到社會主義精神文明建設(shè)中去。關(guān)于課堂練習(xí)，我準(zhǔn)備了5個針對性比較強(qiáng)的選擇題，從而加深鞏固本框題的重難點(diǎn)知識。最后，播放歌曲《走進(jìn)新時代》，展示本課知識結(jié)構(gòu)，指出本框題需重點(diǎn)掌握的問題，結(jié)束本課教學(xué)。課后作業(yè)，我設(shè)計(jì)了這樣一個辨析的題目：文化是人們創(chuàng)造的全部財(cái)富的總和，它是人類特有的現(xiàn)象。

人教版高中英語必修4A taste of English Humor說課稿3篇
Then I would ask them to think of a funny English or Chinese and tell it to partners. While telling stories, they can use expressions and some acting to help make the story funny. 5 minutes would be given to do this.Those stories they told there will be the material for their writing. Soletting them tell it at first is helpful. And they can make a difference between telling a funny story and writing it down. Generally speaking, it is difficult forstudents to write well because they don’t know what to write and how to write. Asking them to tell their own stories at first can help them come up with what to write.After their telling, I would invite someone to share his/her story with all of us and I would write it down on the blackboard.This example story would be used as a sample to illustrate the format of funny story. Different from a story from teacher or textbook, a story from students can obviously become a interesting material to draw students’ attention.Then I would ask the whole class to put this story into several parts. It might be a little bit difficult for them. So I would ask them to find out whether all the sentences are necessary. After delete some sentences, there are 6 sentences left behind. Then they can easily put them into three parts. After interaction with students, I would teach them the right terms for each part and conclude the format of funny story.This step is the key and difficult point in my lesson. So I mainly usetask-based teaching method in this part and the task for students was divided into several stages. With the separated difficult level, students can find there are usually three parts in writing. They can also learn to write without the unnecessary parts in the process of analyzing. And then I wouldn’t rush to tell them the right terms to them directly. Instead, I would ask them to name them by their own. A confused mind is better for acquiring knowledge.While-writing:Then I would give students 7 minutes to write down this story, without other requirements.With all the preparations in pre-writing, students’ difficulties were cleared. So it would be much easier for them to write down the story within 7 minutes. There are no other requirements because students’ first writing is actually a drafting. It would be revise and edit several times later. Writing, as a skill

知識與技能1、指導(dǎo)學(xué)生初步掌握稱謂語、禁忌語、委婉語等交際語言；2、指導(dǎo)學(xué)生根據(jù)具體的語境條件運(yùn)用不同的交際語言，達(dá)到交際目的。過程與方法1、通過故事或習(xí)題分析，掌握有關(guān)交際語言的一些知識；2、講練結(jié)合，有所積累。情感、態(tài)度與價值觀點(diǎn)燃學(xué)生繼承中華傳統(tǒng)文化的熱情，以得體的交際語言營造良好的人際環(huán)境。教學(xué)重點(diǎn)根據(jù)交際中運(yùn)用語言的要求，引導(dǎo)學(xué)生根據(jù)不同的語境條件恰當(dāng)?shù)乇砬檫_(dá)意。教學(xué)難點(diǎn)通過課內(nèi)探索延伸至課外，積累關(guān)于交際中的語言運(yùn)用的一些知識。教學(xué)課時：一課時教學(xué)過程一、導(dǎo)入利用一道口語交際訓(xùn)練題引入本節(jié)課要探究的內(nèi)容。例1：下面的場合，如果班長既想達(dá)到批評的目的，又想把話說得委婉些，表達(dá)恰當(dāng)?shù)囊豁?xiàng)是（C）小李和小楊，為了一點(diǎn)小事，兩人自習(xí)課上大聲地爭吵起來。這時，班長說：A、你們這樣大聲爭吵，影響很壞。B、你們這樣大聲爭吵，難道不感到羞恥吧？
人教版高中政治必修3思想道德修養(yǎng)與文化修養(yǎng)教案
(2)這樣的例子很多，如，有的同學(xué)利用自己掌握的計(jì)算機(jī)知識制造黑客程序，破壞校園網(wǎng)的正常運(yùn)行；有的生產(chǎn)者和經(jīng)營者制假售假，坑蒙拐騙；有的人身上存在著拜金主義傾向；等等。從上面的課堂探究中，我們認(rèn)識到：(1)出現(xiàn)道德沖突的原因：生活變化很快，不斷加快的城鎮(zhèn)化進(jìn)程；新型產(chǎn)業(yè)的崛起與傳統(tǒng)產(chǎn)業(yè)的衰落，使眾多勞動者不得不面對新的擇業(yè)問題；網(wǎng)絡(luò)的普及，使越來越多的人進(jìn)入社會交行的新天地；等等。在急劇變化的社會生活中，人們在告別傳統(tǒng)?；罘绞降耐瑫r，也常常遭遇思想道德下的“兩難選擇”。(2)解決道德沖突的重要途徑解決道德沖突的一個重要的途徑，就是在社會主義精神文明建設(shè)的實(shí)踐中，加強(qiáng)自身知識文化修養(yǎng)和思想道德修養(yǎng)，不斷追求更高的思想道德目標(biāo)?！笳n堂練習(xí)：道德沖突()①是經(jīng)濟(jì)生活日益發(fā)展的反映②不存在于現(xiàn)實(shí)生活中③是一個永遠(yuǎn)無法解決的問題④是社會生活急劇變化的產(chǎn)物
小學(xué)數(shù)學(xué)人教版五年級下冊《第六課體積單位間的進(jìn)率》教案說課稿
（一）復(fù)習(xí)舊知，導(dǎo)入新課。師：同學(xué)們，上節(jié)課我們認(rèn)識了體積和體積單位，請你填一填這兩道題，看看你學(xué)得怎么樣。（課件第2張）1.常用的體積單位有（立方厘米）、（立方分米）、（立方米），可以分別寫成（cm³） 、（dm³）、 （m³）。2.棱長是1cm的正方體，體積是（1cm³）。3.棱長是1dm的正方體，體積是（1dm³）。4.棱長是1m的正方體，體積是（1m³）。【設(shè)計(jì)意圖】1dm³是多少cm³呢？這節(jié)課我們就來研究一下體積單位間的進(jìn)率。（板書課題）（二）探究新知1．探究立方分米和立方厘米間的進(jìn)率：（課件第3張）（1）下圖是一個棱長為1dm的正方體，體積是1dm³。想一想，它的體積是多少立方厘米呢？（2）小組討論，你是怎樣想的？（3）匯報(bào)交流：（課件第4張）生1：如果把它的棱長看作是10cm，可以把它切成1000塊1cm³的小正方體。10×10×10=1000.生2：它的底面積是1dm²，就是100cm²，100×10=1000，一共是1000cm³。1dm³=1000cm³【設(shè)計(jì)意圖】用小組討論的方式，讓學(xué)生從討論的過程中找到解決問題的方法，培養(yǎng)學(xué)生的語言表達(dá)能力、思維能力。2.你知道1m³等于多少立方分米嗎？（課件第5張）生1：把棱長是1m的正方體，看作棱長是10dm的正方體，10×10×10=1000dm³。1m³=1000dm³。 生2：棱長是1m的正方體，底面積是1m²，就是100dm²，100×10=1000dm³，一共是1000dm³。生3：1m³=1000dm³ 3.整理計(jì)量單位之間的進(jìn)率。（1）小組討論：到現(xiàn)在為止，我們已經(jīng)學(xué)習(xí)了哪些計(jì)量單位？請整理在表中。
