教師：不同的時代造就了不同風(fēng)格和不同精神內(nèi)容的詩詞，請同學(xué)們回顧必修一和必修二兩宋中央集權(quán)的加強和經(jīng)濟的發(fā)展?fàn)顩r。學(xué)生：回憶回答。教師：請同學(xué)們結(jié)合時代背景和詞的特點理解詞為什么能夠成為宋代文學(xué)的主流形式和標(biāo)志？學(xué)生：兩宋時經(jīng)濟重心轉(zhuǎn)移到了南方，商業(yè)發(fā)展打破了時間和空間的限制，城市繁榮，市民數(shù)量不斷增加。詞的句子長短不齊，便于抒發(fā)感情，并且能夠歌唱，更能適應(yīng)市井生活的需要。于是，詞成為宋代文學(xué)的主流形式和標(biāo)志。教師：宋代文人地位提高，宋詞就是一個個時代的畫卷：大宋的悲歡離合都寫在了里面。除了詞之外，宋代民間還興起了一種新的詩歌形式，即散曲。學(xué)生：回答散曲的發(fā)展階段及特點、元曲的含義、特點。教師：在中國古代詩歌輝煌發(fā)展的同時，也產(chǎn)生了供人們閑來無事消遣的小說。
人教版高中歷史必修2開辟新航路說課稿3篇
一、說教材《開辟新航路》是高中《歷史·必修二》第5課的內(nèi)容。從三個方面向?qū)W生介紹了歐洲人開辟新航路的歷史：即新航路開辟的原因和條件、新航路開辟經(jīng)過以及影響。前4課內(nèi)容介紹了古代中國經(jīng)濟的基本結(jié)構(gòu)與特點，從第5課開始學(xué)習(xí)資本主義世界市場的形成和發(fā)展。本課內(nèi)容相當(dāng)重要，上承古代中國，下啟近代世界。新航路的開辟，打破了世界相對隔絕的狀態(tài)，世界真正開始融合為一個整體。從此，以西歐為中心的世界市場的雛形開始出現(xiàn)。隨后的殖民擴張，世界市場拓展；第一次工業(yè)革命，世界市場基本形成；第二次工業(yè)革命，世界市場發(fā)展。二、說目標(biāo)1、課程標(biāo)準(zhǔn)概述迪亞士、哥倫布開辟新航路的史實，認(rèn)識地理大發(fā)現(xiàn)對世界市場形成的意義。2、三維目標(biāo)①知識與能力：掌握新航路開辟的原因、經(jīng)過、影響。②過程與方法：引導(dǎo)學(xué)生分析原因及影響，培養(yǎng)學(xué)生分析和歸納問題的能力。③情感態(tài)度與價值觀：A、通過對新航路開辟過程的學(xué)習(xí)，使學(xué)生感受和學(xué)習(xí)探險家們勇于進(jìn)取的開拓精神。B、通過學(xué)習(xí)新航路開辟的影響，使學(xué)生認(rèn)識新航路開辟促進(jìn)了人類社會的整體發(fā)展。
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)濟發(fā)展服務(wù)。運用所學(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，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？
人教版高中政治必修3感受文化影響說課稿
（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。“深遠(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。
人教版高中政治必修3建設(shè)學(xué)習(xí)型社會說課稿
解析：材料是講學(xué)習(xí)型社會所產(chǎn)生的影響，A項觀點錯誤，在當(dāng)前和今后相當(dāng)長的時間里，學(xué)校教育仍然是人們獲得知識的最重要的途徑。B項觀點錯誤，終身學(xué)習(xí)只是成就人生目的的手段、途徑，而不是目的本身。D項說法錯誤，當(dāng)前我國社會的中心工作是經(jīng)濟建設(shè)。二、問答題5.材料一：日本是公認(rèn)的漫畫大國，日本的動漫產(chǎn)業(yè)產(chǎn)值每年230萬億日元，成為日本的第二大支柱產(chǎn)業(yè)。在日本，漫畫比電影、小說有時甚至比電視或音樂更受歡迎。日本漫畫的熱潮還席卷了世界：日本每年出口到美國的卡通片價值就達(dá)5 000億日元，是日本對美國鋼鐵出口金額的4倍；漫畫中的人物被迅速復(fù)制成電子游戲、卡通片及真人演出的節(jié)目。原來只是閑暇時候消遣的漫畫，正飛速滲透到人們的生活中。值得警惕的是，除了催人奮進(jìn)的精華之外，日本漫畫中也存在暴力、色情、扭曲歷史等諸多糟粕，對缺乏辨別能力的青少年產(chǎn)生了許多不良影響，更引發(fā)了一系列深刻的社會問題。
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、政治在經(jīng)濟基礎(chǔ)上相互影響。①經(jīng)濟、政治和文化是社會生活的三個基本領(lǐng)域。其中，經(jīng)濟是基礎(chǔ)，政治是經(jīng)濟的集中表現(xiàn)，文化是經(jīng)濟和政治的反映。一定的文化由一定的經(jīng)濟、政治所決定，又反作用于一定的政治、經(jīng)濟，給予政治、經(jīng)濟以重大影響。②經(jīng)濟發(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、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、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。

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，具有很強的思想理論性和探索實踐性。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、難點和落腳點。2、教學(xué)目標(biāo)（1）知識與能力目標(biāo)：①識計文化創(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。

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

人教版新課標(biāo)高中物理必修1彈力說課稿3篇
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。]

大班幼兒所擁有的經(jīng)驗和技能使他樂于自我發(fā)現(xiàn)和探索，他們不滿足于知識的傳授而更愿意通過自己的努力獲得更多的經(jīng)驗和知識。同時，他也能夠通過同伴間的合作完成更艱難和具有挑戰(zhàn)性的任務(wù)，享受成功的滿足?！秳趧诱叩墓ぞ摺匪@現(xiàn)的內(nèi)容是完全靜態(tài)的成品。大班幼兒會滿足于這樣的學(xué)習(xí)方式嗎？怎樣讓靜態(tài)的東西動起來，成為孩子樂于探索，能夠發(fā)現(xiàn)的新材料呢？正確選擇跟學(xué)習(xí)材料適合和匹配的教學(xué)方法，讓枯燥的認(rèn)知活動成為快樂的事，是成功開展本次活動的精髓。思路定位：1.選擇幼兒熟知的、同時具有安全操作性日常生活工具作為本次科學(xué)活動的探索和認(rèn)知對象。引導(dǎo)幼兒用“陌生”的眼光去重新審視熟悉的材料，激發(fā)好奇心和活動的興趣，2.讓靜態(tài)的材料“動”起來。將認(rèn)知的重點從被動接受轉(zhuǎn)移到主動發(fā)現(xiàn)探索上。通過幼兒的親歷親為去發(fā)現(xiàn)工具的特點，并通過與同伴的交流探討建構(gòu)成新的內(nèi)需的知識。3.在與同伴的合作中常識使用工具并獲得成功的體驗。通過操作和實踐來驗證自身的發(fā)現(xiàn)，同時也進(jìn)一步了解工具與人類生活的關(guān)系。具體教案與環(huán)節(jié)分析：［活動目標(biāo)］1.運用多種感官探索和發(fā)現(xiàn)工具的秘密，積極探討交流自己的發(fā)現(xiàn)和見解。2.嘗試和同伴合作使用某一工具完成任務(wù)，體驗合作的快樂和嘗試的成功。3.初步了解工具與人類生活的關(guān)系，激發(fā)自豪感。
