人教版高中生物必修2遺傳密碼的破譯說課稿
3、遺傳密碼的特點 連續(xù)性、簡并性、通用性5、課堂練習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、教學反思1、教材中豐富的科學史料，是我們在課堂上進行探究性學習活動的良好素材，教師要整理和運用好。千萬不要低估學生的思維能力，當學生的思維能力被你想方設法激發(fā)出來的時候，你會發(fā)現他們的創(chuàng)造力是無窮的。2、探究性學習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研究方法，培養(yǎng)合作與分享的精神以及實事求是的科學態(tài)度，鍛煉思維能力，提高科學素養(yǎng)。3、學生是學習的主體，教師是引導者。我們要采取措施讓學生積極主動地參與到學習活動中來，通過他們的思考、討論、爭辯、合作等活動來獲取方法，建構知識。
人教版高中歷史必修3明清之際活躍的儒家思想說課稿2篇
這是略帶提高性的問題，旨在提高學生認識歷史的能力，搞清這一歷史問題有助于理解中西歷史發(fā)展的不同。（學生討論，教師總結歸納并展示。）不是資產階級民主思想，因為它們是資本主義萌芽的產物，資產階級作為一個階級還沒有產生。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，更沒有認識到人的基本權利。它沒有成為主流思想，因此沒有促進明清社會的轉型，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生、發(fā)展缺乏強有力的物質基礎。（2）中國傳統文化的束縛和影響。（3）高度強化的專制中央集權制度的壓制使早期民主思想未能形成完整的體系。
人教版高中歷史必修1新中國的民主政治建設說課稿2篇
（一）教材的地位新中國的成立是20世紀的一件大事。它結束了幾千年封建專制統治的歷史，開啟了中華民族發(fā)展的新紀元。本課側重這一時期一個非常顯著的特征，即制度的更新，它本身具有知識的延續(xù)性和鋪墊性。新中國的成立促進了社會經濟的發(fā)展，也為祖國的統一奠定了重要基礎。（二）教學目標依據新課程以人為本，促進學生全面發(fā)展的要求，同時,針對高一年級學生具備一定基礎知識但掌握不牢固，對歷史興趣濃厚但又自制能力差的特點，我對本課的三維目標設定如下：見多媒體。（三）教學重點的確定及處理本課的主題是新中國的民主政治建設，這個問題的掌握對以后學習中國民主政治建設的進程有很大幫助，并且學生能力的提高也有賴于對它的認識，所以確定“人民代表大會制度的創(chuàng)立”是教學重點。

人教版高中歷史必修1從漢至元政治制度的演變說課稿2篇
二、君主專制的演進（即中央政治制度的演變）通過地方政治制度演變的學習，掌握方法以后，以學生歸納整理基本線索為主，教師適當點撥，注意糾錯。1． 漢承秦制，又有所變化。教師點撥強調繼承與發(fā)展兩個方面。創(chuàng)設情景：同學們看了電視連續(xù)劇《漢武大帝》后，知道漢武帝劉徹在繼位之后，就急于對西漢王朝的政治制度進行改革。那么，西漢初期中央政治制度的基本框架是怎樣的呢？漢武帝為什么要對它進行改革呢？改革后的西漢中央集權制度又是怎樣的呢？請大家議一議，想一想。主干知識：西漢初期的中央政治制度的最大特點是“漢承秦制”。具體表現在兩個方面：一是繼續(xù)實行皇帝制度，維護皇權，這一做法也為后來各王朝所沿用；二是在中央設立三公，分別掌管行政、監(jiān)察和軍事。到漢武帝時，“中朝”成為西漢重要的中央決策機構，尚書令的權力日益重要，以丞相為首的三公九卿的權力被削弱，演化為執(zhí)行機構。到了東漢光武帝時，進一步剝奪三公權限，擴大尚書的權力。
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展說課稿
1789年法國大革命后，共和派與君主派之間進行了長期反復的斗爭，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一步發(fā)展奠定了基礎。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。但資產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世紀末躋身到世界強國行列。資本主義政治制度擴展到了歐洲大陸，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 （2）原因2、確立標志：法蘭西第三共和國憲法

人教版高中歷史必修1甲午中日戰(zhàn)爭說課稿
3．甲午中日戰(zhàn)爭中國戰(zhàn)敗的原因 對于“中國戰(zhàn)敗的原因”這一難點的突破，主要通過設置問題“中國之敗敗在實力遜于日本嗎？”通過幻燈片全方位分析其實中國的綜合國力當時是強于日本的。并且在戰(zhàn)前，日本毫無取勝的把握。讓學生結合剛學習過的戰(zhàn)爭原因和經過進行討論，從多方面分析中國戰(zhàn)敗的原因。經過討論，學生可以得出以下結論：避戰(zhàn)自保方針，沒有積極備戰(zhàn)，將領臨陣脫逃，教師肯定并總結答案進行補充。中日對比：中國士兵出身農民，軍事訓練落后，散兵游勇；日本士兵出身武士，訓練有素；中國將領大多臨陣脫逃，并相互猜忌，受當時惡劣的官風影響；李鴻章深知北洋海軍實情，缺乏軍費，軍備廢弛。為政治資本奉行避戰(zhàn)自保政策，慈禧太后挪用海軍軍費過壽，支持李鴻章。使中方處于被動的局面，一再貽誤戰(zhàn)機。而日本在天皇的帶動下，全民備戰(zhàn)，做了充分的戰(zhàn)爭準備。

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
