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

人教版高中歷史必修2物質(zhì)生活與習(xí)俗的變遷說課稿2篇
【課外延伸】閱讀思考：1、改革開放以來，東西方文明的交流、碰撞更加劇烈。對于外來文化，目前有不同的觀點，現(xiàn)引入兩種觀點：觀點1：這是一種進(jìn)步。改革開放以來，中國不斷發(fā)展，這時候舊的文化顯然是不合時宜的，西方文化的進(jìn)入，給我們帶來了新的生活方式和生活態(tài)度，中國逐漸改掉了一些陋習(xí)，與世界接軌。觀點2：這是一種文化侵略。西方文化的進(jìn)入，使中國傳統(tǒng)文化一步步淪喪，特別是我們過著西方圣誕節(jié)時，中國的傳統(tǒng)節(jié)日端午節(jié)已被韓國申報為非物質(zhì)文化遺產(chǎn)。這告訴我們，我們應(yīng)該保護(hù)我們的傳統(tǒng)文化。面對東西方文化的交匯、碰撞，你認(rèn)為該怎樣正確看待外來文化和傳統(tǒng)文化？請寫篇小論文闡述你的觀點。2、設(shè)計以下表格：利用搜集的資料按照“衣、食、住、行、風(fēng)俗”五部分進(jìn)行比較，再將現(xiàn)代社會物質(zhì)生活和習(xí)俗細(xì)分為“辛亥革命前和辛亥革命后”兩部分內(nèi)容進(jìn)行比較。
人教版高中政治必修3色彩斑斕的文化生活說課稿3篇
根據(jù)課標(biāo)要求，參照教科書，支撐這一問題解決的知識有：⑴文化生活的特點；⑵文化生活的兩面性；⑶發(fā)展文化生活的基本要求。其中重點問題是辨別文化生活的“喜”與“憂”。只有辨別清楚，才能趨利避害，才能積極主動的參與健康向上的文化生活。從而為怎樣發(fā)展為人民大眾所喜聞樂見的文化打下基礎(chǔ)。由于高二學(xué)生尚未學(xué)習(xí)哲學(xué)知識，所以它也是本節(jié)的一個難點，同時，由于學(xué)術(shù)界對什么是大眾文化，大眾文化有那些基本特征，存在著分歧，所以正確把握大眾文化的含義也成為本節(jié)課的一個難點。三、學(xué)情分析：應(yīng)該說高二學(xué)生已經(jīng)參與了不少的文化生活。但由于其正處在三觀形成的關(guān)鍵時期，對文化生活的參與還比較盲目，缺少理性思考，以至付出沉重的代價。很顯然通過本框的學(xué)習(xí)，學(xué)生會更加理性的參與文化生活，從而健康茁壯的發(fā)展、成長。四、教學(xué)目標(biāo)：基于以上分析，我將本框題的教學(xué)目標(biāo)確定為以下三個方面：（1）知識目標(biāo)：了解目前我國文化生活的現(xiàn)狀，知道人們的文化生活是色彩斑斕的，但也存在令人憂慮的現(xiàn)象；把握大眾文化的豐富內(nèi)涵；明確發(fā)展為人民大眾所喜聞樂見的文化必須堅持的原則、方針等。

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，精神文化就不可能搞好的觀點，不符合歷史發(fā)展的事實，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：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。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：（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。

（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)計這個作業(yè)的意圖是既讓學(xué)生靈活運用所學(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)計遵循板書設(shè)計的實用性、直觀性的原則，根據(jù)本課的教材特點，我采用結(jié)構(gòu)式板書，這樣設(shè)計比較直觀、系統(tǒng)，以便于學(xué)生能夠系統(tǒng)把握和理解知識。

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)，指出本框題需重點掌握的問題，結(jié)束本課教學(xué)。課后作業(yè)，我設(shè)計了這樣一個辨析的題目：文化是人們創(chuàng)造的全部財富的總和，它是人類特有的現(xiàn)象。

基于以上分析，為使本堂課圍繞重點、突破難點，同時讓學(xué)生在課堂教學(xué)中能力得到提高，我設(shè)計如下教學(xué)過程。（一）創(chuàng)設(shè)情景認(rèn)識形變由同學(xué)們已有的形變知識入手，引入新課。教師演示：①彈簧的壓縮形變；②彈簧的拉伸形變③視頻播放：竹竿形變、鋼絲的扭轉(zhuǎn)形變。得出形變的概念及各類形變。[設(shè)計意圖：我從生活情景中引入新課，是為了激發(fā)學(xué)生的好奇心，為學(xué)生學(xué)習(xí)重點和難點內(nèi)容作鋪墊。]設(shè)問：摩天大樓在風(fēng)的吹拂下會不會擺動，發(fā)生形變嗎？演示微小形變放大實驗：由于這種形變不容易觀察，會使學(xué)生產(chǎn)生疑問：到底有沒有發(fā)生形變？解決的辦法是微小形變的演示實驗。為什么光點會往下移？讓學(xué)生帶著問題思考后得出結(jié)論：是由于桌面發(fā)生了形變，但是形變不明顯。為后面解決壓力和支持力都是彈力做好鋪墊。[設(shè)計意圖：使學(xué)生知道“放大”是一種科學(xué)探究的方法。]

通過這個示例呢，我們可以得到解決向心力問題的一般的步驟，確定對象，找出軌跡，找出圓心，然后進(jìn)行受力分析，讓同學(xué)們參考這樣的步驟，逐步的解決圓周運動的問題，對于變速圓周運動，我通過鏈球運動進(jìn)行引入，這里是一個鏈球運動的視頻，在同學(xué)們觀看視頻之前，我給同學(xué)們提出問題，鏈球收到繩子的拉力，做的是勻速圓周運動嗎？ 然后再課堂上我們再做一個小實驗， 我們可以通過改變拉線的方式來調(diào)節(jié)小球的速度大小嗎？ 那么對小球，做加速圓周運動，進(jìn)行受力分析，我們可以看到，小球做加速運動時，他所受到的力，并不是嚴(yán)格通過軌跡的圓心，在進(jìn)行分析的時候，特別強(qiáng)調(diào)，小桶所受力的切線方向分力，和法線方向分力，切線方向分力，改變小球運動速度大小，法線方向分力，改變了小球運動的方向，法線方向的分力，在這里就是向心力，產(chǎn)生了向心加速度，通過這樣一個例子進(jìn)行分析，同學(xué)們是比較容易理解的，

1、課題引入：我設(shè)計以提問哲學(xué)到底是什么？的問題激發(fā)學(xué)生的閱讀興趣。我設(shè)計典型事例，通過學(xué)生討論，教師總結(jié)的形式，并得出其實哲學(xué)就在我們身邊。2、講授新課：（35分鐘）通過教材第一目的講解，讓學(xué)生明白，生活和學(xué)習(xí)中有許多蘊涵哲學(xué)道理的故事，表明哲學(xué)并不神秘總結(jié)并過渡：生活也離不開哲學(xué)，哲學(xué)可以是我正確看待自然、人生、和社會的發(fā)展，從而指導(dǎo)人們正確的認(rèn)識和改造世界。整個過程將伴隨著多媒體影像資料和生生對話討論以提高學(xué)生的積極性。3、課堂反饋，知識遷移。最后對本科課進(jìn)行小結(jié)，鞏固重點難點，將本課的哲學(xué)知識遷移到與生活相關(guān)的例子，實現(xiàn)對知識的升華以及學(xué)生的再次創(chuàng)新；可使學(xué)生更深刻地理解重點和難點，為下一框?qū)W習(xí)做好準(zhǔn)備。

3、清代的“閉關(guān)鎖國”政策：（1）原因：①根本原因：自給自足的封建自然經(jīng)濟(jì)；②客觀原因：西方殖民者向東方殖民擴(kuò)張；③直接原因：對付東南沿海人民的抗清斗爭（2）內(nèi)容：嚴(yán)格限制對外貿(mào)易。但并不是禁絕海外貿(mào)易?？滴跬砥冢股倘饲巴涎筚Q(mào)易；乾隆時只開廣州一處通商，并設(shè)立政府特許的貿(mào)易機(jī)構(gòu)廣州“十三行”統(tǒng)一經(jīng)營管理對外貿(mào)易。（3）后果：①閉關(guān)鎖國政策妨礙了海外市場的開拓，抑制了資本的原始積累，從而阻礙了資本主義萌芽的發(fā)展。②閉關(guān)鎖國政策隔絕了中國與外界的聯(lián)系，從而阻斷了中國學(xué)習(xí)西方的先進(jìn)科學(xué)技術(shù)，阻礙了生產(chǎn)力發(fā)展，使中國落后于世界潮流。③“閉關(guān)鎖國”政策在一定程度上也保護(hù)了國家的安全。教師可以設(shè)置問題：17-18世紀(jì)中國顯露出哪些危機(jī)？
