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3新文化運動與馬克思主義的傳播說課稿
一、說教材（一）教材分析本課所介紹的新文化運動，是繼上一節(jié)所學(xué)的《西學(xué)東漸和維新變法思想》之后中國另一波影響巨大的思想解放潮流，旨在向西方學(xué)習(xí)、尋求強國御侮之道。在整個知識體系中，它既是資產(chǎn)階級領(lǐng)導(dǎo)的舊民主主義革命的補課，又是無產(chǎn)階級領(lǐng)導(dǎo)的新民主主義革命的序曲。它所帶來的思想的空前解放，也就為馬克思主義的傳播創(chuàng)造了條件，為中共的成立奠定基礎(chǔ)。這一課的學(xué)習(xí)能讓學(xué)生清晰認(rèn)識新文化運動和馬克思主義在近代中國思想解放歷程中的重要作用和巨大影響。與必修一和必修二政治經(jīng)濟史的結(jié)合也能讓使學(xué)生強化歷史聯(lián)系。新課程標(biāo)準(zhǔn)對本課就做了明確的規(guī)定：1、概述新文化運動的主要內(nèi)容，探討其對近代中國思想解放的影響。2、簡述馬克思主義在中國傳播的史實，認(rèn)識馬克思主義對中國歷史發(fā)展的重大意義。根據(jù)課標(biāo)要求，我制定了以下具體的三維目標(biāo)。

這是略帶提高性的問題，旨在提高學(xué)生認(rèn)識歷史的能力，搞清這一歷史問題有助于理解中西歷史發(fā)展的不同。（學(xué)生討論，教師總結(jié)歸納并展示。）不是資產(chǎn)階級民主思想，因為它們是資本主義萌芽的產(chǎn)物，資產(chǎn)階級作為一個階級還沒有產(chǎn)生。中國民主思想只停留在批判的層次上，并沒有提出新的思想，更沒有認(rèn)識到人的基本權(quán)利。它沒有成為主流思想，因此沒有促進明清社會的轉(zhuǎn)型，尚未突破封建思想的束縛。而啟蒙思想集中力量批判專制主義、教權(quán)主義，描繪了未來資本主義社會的宏偉藍圖，開成了強大的社會思潮，推動了社會向資本主義社會的轉(zhuǎn)變。原因：（1）明清之際的資本主義萌芽較為脆弱，使早期民主思想的產(chǎn)生、發(fā)展缺乏強有力的物質(zhì)基礎(chǔ)。（2）中國傳統(tǒng)文化的束縛和影響。（3）高度強化的專制中央集權(quán)制度的壓制使早期民主思想未能形成完整的體系。

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；②客觀原因：西方殖民者向東方殖民擴張；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?，禁止商人前往南洋貿(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？

3、遺傳密碼的特點 連續(xù)性、簡并性、通用性5、課堂練習(xí)6、作業(yè)布置假如，我們利用(ACU)n核苷酸長鏈合成了含有蘇氨酸的多肽，那么蘇氨酸可能的密碼子有哪些？如何運用實驗方法確證蘇氨酸的密碼子究竟是什么？七、教學(xué)反思1、教材中豐富的科學(xué)史料，是我們在課堂上進行探究性學(xué)習(xí)活動的良好素材，教師要整理和運用好。千萬不要低估學(xué)生的思維能力，當(dāng)學(xué)生的思維能力被你想方設(shè)法激發(fā)出來的時候，你會發(fā)現(xiàn)他們的創(chuàng)造力是無窮的。2、探究性學(xué)習(xí)的目的并不僅僅是問題的解決，更重要的是在探究過程中體驗和獲取科學(xué)研究方法，培養(yǎng)合作與分享的精神以及實事求是的科學(xué)態(tài)度，鍛煉思維能力，提高科學(xué)素養(yǎng)。3、學(xué)生是學(xué)習(xí)的主體，教師是引導(dǎo)者。我們要采取措施讓學(xué)生積極主動地參與到學(xué)習(xí)活動中來，通過他們的思考、討論、爭辯、合作等活動來獲取方法，建構(gòu)知識。
人教版高中生物必修1細胞的癌變說課稿
5．5癌癥的預(yù)防作為本節(jié)最重要內(nèi)容，且與生活息息相關(guān)，我采用老師引導(dǎo)、學(xué)生討論總結(jié)的方法進行教學(xué)。從生活各方面總結(jié)出保健良方 ，既對知識有很好應(yīng)用，又體現(xiàn)對生命的熱愛。此時，本節(jié)課達到高潮，同學(xué)們意氣風(fēng)發(fā)，熱烈討論，實現(xiàn)本節(jié)課的教學(xué)目標(biāo)。5．6 癌癥的治療通過講述癌癥治療方法的副作用，激發(fā)學(xué)生探究生物學(xué)欲望，激勵學(xué)生立志除癌。 在此，我選用一則關(guān)于一名癌癥晚期病人運用心理療法成功戰(zhàn)勝癌癥的故事，在于對不同層次的學(xué)生進行多方面啟發(fā)教育，體現(xiàn)面向全體學(xué)生的課程理念。5．7 愉悅總結(jié)，及時反饋本節(jié)知識點零散，我將帶領(lǐng)學(xué)生回憶瀏覽本節(jié)內(nèi)容，使零散知識點系統(tǒng)化。在課堂反饋環(huán)節(jié)，我通過簡單練習(xí)采用分組競答的方式把握學(xué)生對知識的掌握程度，并給予表現(xiàn)突出的學(xué)生適當(dāng)獎勵，這是本節(jié)課第三個亮點。競答既使課堂顯得緊湊、集中，又有利于形成學(xué)生的競爭意識，還使得學(xué)生的知識得以鞏固應(yīng)用。
人教版高中生物必修1細胞的衰老與凋亡說課稿
4、最后從生物的壽命引入，探討細胞的死亡。強調(diào)細胞死亡有兩種形式。(1).細胞壞死，它是由某些外界因素造成細胞急速死亡，是一種被動性死亡；(2).細胞凋亡，這是一種由特定基因控制的主動性死亡。細胞壞死與細胞凋亡在形態(tài)學(xué)和生物化學(xué)上有著明顯的區(qū)別。細胞凋亡有廣泛的生物學(xué)意義，比如胚胎發(fā)育期手的發(fā)育如果沒有細胞的調(diào)亡就不會有纖細的手指；如果沒有正常的細胞調(diào)亡，蝌蚪的尾部就不會消失，它將永遠不能變成青蛙……。正常的細胞調(diào)亡還肩負(fù)著維持各種組織器官固有體積和形態(tài)的功能；還會使機體內(nèi)異常的細胞得到及時清除，去處潛在的隱患；例如癌癥就是異常的細胞沒有及時死亡的結(jié)果……。因此細胞的正常死亡是生物體的一種非常重要的調(diào)節(jié)機制，是機體平衡細胞增殖，調(diào)節(jié)機體細胞樹木恒定的方式，是必不可少的生命過程。（15分鐘）5、課堂小結(jié)，可以把課堂傳授的知識盡快地轉(zhuǎn)化為學(xué)生的素質(zhì)；簡單扼要的課堂小結(jié)，可使學(xué)生更深刻地理解政治理論在實際生活中的應(yīng)用，并且逐漸地培養(yǎng)學(xué)生具有良好的個性。
