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

二、說學(xué)情本課的教學(xué)對象為高二學(xué)生，他們思維活躍已具備一定歸納能力和分析、綜合能力，能夠自主地分析現(xiàn)實(shí)生活中的一些文化行為，但看問題往往比較偏激、片面，缺乏良好的邏輯思維能力。所以，在文化創(chuàng)新的途徑上要對他們進(jìn)行指導(dǎo)，以免走入誤區(qū)。三、教學(xué)目標(biāo)根據(jù)新課程標(biāo)準(zhǔn)、教材特點(diǎn)、學(xué)生的實(shí)際，我確定了如下教學(xué)目標(biāo)：【知識與能力目標(biāo)】1.理解文化創(chuàng)新的根本途徑和兩個基本途徑;2.了解文化創(chuàng)新過程中需要堅持正確方向，克服錯誤傾向。
人教版高中歷史必修2從“戰(zhàn)時共產(chǎn)主義”到“斯大林模式”說課稿2篇
【課堂小結(jié)】本課主要講述俄國十月革命后進(jìn)行經(jīng)濟(jì)建設(shè)，并在建設(shè)中進(jìn)行社會主義探索，期間先后出現(xiàn)了戰(zhàn)時共產(chǎn)主義政策、新經(jīng)濟(jì)政策和斯大林模式，這些政策和體制的產(chǎn)生都是歷史和當(dāng)時現(xiàn)實(shí)有關(guān)，但也反映出在建設(shè)社會主義中既有成功的也由重大失誤，主要在于缺乏現(xiàn)成的政策和模式可供借鑒，更在于理論上的缺乏。斯大林模式的形成同蘇聯(lián)當(dāng)時社會生產(chǎn)力的發(fā)展水平相適應(yīng)，它在初期和戰(zhàn)爭時期曾發(fā)揮了巨大作用，使蘇聯(lián)成為強(qiáng)大的社會主義國家。它建立的高度集中的計劃經(jīng)濟(jì)體制和新型的工業(yè)化模式是蘇聯(lián)進(jìn)行社會主義建設(shè)中的探索和創(chuàng)新，對二戰(zhàn)后社會主義國家產(chǎn)生了深刻影響，促進(jìn)這些國家國民經(jīng)濟(jì)的恢復(fù)和發(fā)展，形成了足以同資本主義相抗衡的社會主義陣營。但是，它沒有解決社會主義民主政治建設(shè)和經(jīng)濟(jì)運(yùn)行的一系列根本問題，違背了列寧關(guān)于把文化經(jīng)濟(jì)建設(shè)當(dāng)作工作重心的指示，仍把政治斗爭放在第一位。
人教版高中生物必修3第六章第二節(jié)《保護(hù)我們共同的家園》說課稿
1.潛在價值──某種不知名的昆蟲。間接價值──每個物種都維系著它們所在的生態(tài)系統(tǒng)的結(jié)構(gòu)和功能。直接價值──蘆葦是一種重要的造紙原料；蟬蛻是一種動物性藥物；魯班通過觀察某種葉片的葉緣得到啟示，研制出了木工用的鋸；海洋和森林等生態(tài)系統(tǒng)能陶冶情操、激發(fā)創(chuàng)作的靈感。2.主要的困難是，一些發(fā)達(dá)國家（如美國、加拿大和歐盟國家等），拒絕核準(zhǔn)或遲遲不予核準(zhǔn)該議定書。主要爭議的問題是，這些國家擔(dān)心影響本國經(jīng)濟(jì)的發(fā)展和其他國家可能不承擔(dān)相應(yīng)的責(zé)任。例如，美國政府在2003年3月以“減少溫室氣體排放將會影響美國經(jīng)濟(jì)發(fā)展”和“發(fā)展中國家也應(yīng)該承擔(dān)減排和限排溫室氣體的義務(wù)”為由，宣布拒絕執(zhí)行《京都議定書》。建議世界各國特別是發(fā)展中國家聯(lián)合起來，通過聯(lián)合國大會和各國的政府以及民間組織等多種途徑，呼吁每年大量產(chǎn)生溫室氣體的發(fā)達(dá)國家率先核準(zhǔn)《京都議定書》（我國政府早在2002年9月就核準(zhǔn)了《京都議定書》）。

人教版高中歷史必修1資本主義政治制度在歐洲大陸的擴(kuò)展說課稿
1789年法國大革命后，共和派與君主派之間進(jìn)行了長期反復(fù)的斗爭，直到1875年法蘭西第三共和國憲法通過才最終確立了共和政體，它為法國資本主義的進(jìn)一步發(fā)展奠定了基礎(chǔ)。專制色彩濃厚的普魯士通過王朝戰(zhàn)爭這種自上而下的形式，完成了德國的統(tǒng)一。1871年德意志帝國憲法頒布，德國君主立憲政體確立，保留了濃厚的專制殘余和軍國主義傳統(tǒng)。但資產(chǎn)階級代議制的建立使德國的資本主義工業(yè)迅速發(fā)展起來，19世紀(jì)末躋身到世界強(qiáng)國行列。資本主義政治制度擴(kuò)展到了歐洲大陸，隨著這兩個國家資本主義政治制度的確立，近代西方主要資本主義政治制度得以最終確立。四、板書一、法國共和政體確立的艱難歷程1、艱難 （1）表現(xiàn) （2）原因2、確立標(biāo)志：法蘭西第三共和國憲法
人教版高中歷史必修1夏、商、西周的政治制度說課稿3篇
二、教學(xué)目標(biāo)：（一）知識與能力：學(xué)生了解夏商周期的政治制度的內(nèi)容和特點(diǎn)，對不同的政治制度有一個較為全面的認(rèn)識。在此基礎(chǔ)上，學(xué)生根據(jù)所學(xué)的知識，歸納和評價從夏到周政治發(fā)展的特點(diǎn)以及內(nèi)在規(guī)律。（二）過程與方法：在學(xué)習(xí)的過程中，采用小組合作討論的形式，讓學(xué)生學(xué)會與他人合作與溝通，提高自主探究的技能。（三）情感態(tài)度與價值觀：政治制度的不斷更新是古人制度創(chuàng)新的結(jié)果，而這種制度的不斷更新也推動文明的發(fā)展。這是古代先民的智慧結(jié)晶，學(xué)生要引以為豪。而通過本課的學(xué)習(xí)，可以增強(qiáng)學(xué)生們的民族自豪感。三、說教科書：本課作為高中歷史教材的開篇，是認(rèn)識整個古代政治文明史的起點(diǎn)，具有統(tǒng)領(lǐng)和示范作用。本課總共有三個子目,主要講述了夏商周的政治制度。主要介紹了夏朝公共權(quán)力的出現(xiàn)，分封制的內(nèi)容、分封的對象、 “以嫡長子繼承制為核心的宗法制度”介紹了宗法制的來源、內(nèi)容，以及禮樂制度的大致內(nèi)容。
人教版高中生物必修1生命活動的主要承擔(dān)者—蛋白質(zhì)說課稿
第五，蛋白質(zhì)的功能。蛋白質(zhì)功能具有多樣性，由學(xué)生對照教材，進(jìn)行總結(jié)。為什么蛋白質(zhì)有那么多功能呢？根據(jù)我們學(xué)習(xí)生物學(xué)的經(jīng)驗(yàn)可知道：生物的結(jié)構(gòu)決定功能。再要求剛才的那四個同學(xué)上臺組合多肽鏈。以不同位置組合，就會形成很多種多肽鏈，進(jìn)而形成很多種蛋白質(zhì)。每一種蛋白質(zhì)都有其特定的功能，所以蛋白質(zhì)具有多樣性，其功能也具有多樣性。第六，總結(jié)。蛋白質(zhì)是細(xì)胞和生物體中重要的有機(jī)化合物，是一切生命活動的主要承擔(dān)者。蛋白質(zhì)的多樣性是形形色色生物和絢麗多彩生命活動的物質(zhì)基礎(chǔ)。（可以由學(xué)生總結(jié)）第七，教學(xué)評價。由于只有一節(jié)課時間，課堂上對重點(diǎn)、難點(diǎn)知識的解析還不能做到舉一反三的深度，因此盡管學(xué)生課堂反應(yīng)熱烈，對知識點(diǎn)的接受程度也達(dá)到了預(yù)期的要求，但在做課后練習(xí)時，也會出現(xiàn)一些問題。所以傳統(tǒng)的講練結(jié)合還是要結(jié)合起來運(yùn)用才能取得更好的效果。為此本節(jié)內(nèi)容需要2課時來完成。

什么因素可以阻止種群間基因交流呢？由此可引出隔離的概念。學(xué)生初步理解隔離的概念之后，可以安排學(xué)生討論隔離的各種可能的方式，教師歸納出隔離的類型。然后組織學(xué)生閱讀分析教材中的“資料分析”，組織討論“資料分析”中提出的幾個問題。最后教師應(yīng)強(qiáng)調(diào)，一般情況下，地理隔離是生殖隔離的先決條件，生殖隔離一旦形成，原來屬于一個物種的兩個種群，就成了兩個物種。關(guān)于“共同進(jìn)化與生物多樣性的形成”內(nèi)容的教學(xué)，可以學(xué)生自學(xué)為基礎(chǔ)，教師提出一些具有啟發(fā)性的問題，師生共同歸納總結(jié)的方式推進(jìn)教學(xué)過程。使學(xué)生理解共同進(jìn)化的含義，無機(jī)環(huán)境的變化、無機(jī)環(huán)境的復(fù)雜化和多樣化、有性生殖的出現(xiàn)和生態(tài)系統(tǒng)結(jié)構(gòu)的復(fù)雜化和多樣化對生物多樣性形成的作用。最后，組織學(xué)生討論生物進(jìn)化理論在發(fā)展。
人教版高中生物必修2現(xiàn)代生物進(jìn)化理論的由來說課稿
一,說教材1. 教材的地位和作用本章課程的核心是介紹現(xiàn)代生物進(jìn)化理論.生物進(jìn)化理論的發(fā)展和其他科學(xué)理論的發(fā)展一樣,不是簡單的新理論對舊理論的否定和排斥,而是新理論對舊理論的修正,深入和擴(kuò)展.從拉馬克的進(jìn)化學(xué)說到達(dá)爾文的自然選擇學(xué)說,以及現(xiàn)代進(jìn)化理論的由來,大體都走過了這樣的軌跡.這些應(yīng)該成為處理本節(jié)教學(xué)內(nèi)容的基本脈絡(luò).本節(jié)內(nèi)容包括:拉馬克的進(jìn)化學(xué)說,達(dá)爾文的自然選擇學(xué)說和達(dá)爾文以后生物進(jìn)化理論的發(fā)展,其中重點(diǎn)是達(dá)爾文的自然選擇學(xué)說.生物進(jìn)化論不僅是生物學(xué)中具有重要地位的基礎(chǔ)理論,也是對人們的自然觀和世界觀有著重要影響的理論.學(xué)生通過本章內(nèi)容的學(xué)習(xí),不僅可以了解生物進(jìn)化理論在達(dá)爾文之后的發(fā)展,進(jìn)一步樹立生物進(jìn)化的觀點(diǎn)和辯證唯物主義觀點(diǎn),而且能夠通過學(xué)習(xí)進(jìn)化理論的發(fā)展過程,加深對科學(xué)本質(zhì)的理解和感悟.
