人教版新課標高中物理必修2驗證機械能守恒定律說課稿
一、 教材分析與學情分析教材分析人民教育出版社普通高中課程標準實驗教科書必修2第七章第九節(jié)。本節(jié)內容安排在學習機械能守恒定律之后的目的，是為了使學生在理論上對機械能守恒定律有所了解的基礎上，通過實驗測量及對實驗數(shù)據(jù)的分析處理，對機械能守恒定律及條件有深刻的認識。學情分析知識層面：學生已經掌握了動能、重力勢能等概念以及動能定理、機械能守恒定律等定理、定律；知道功是能量轉換的量度以及機械能守恒的條件。能力層面：學生已具備一定的實驗操作技能，會用打點計時器以及直尺等實驗儀器。具備一定的數(shù)據(jù)處理能力。二、教學目標與重點、難點教學目標知識與技能：1、會用打點計時器打下的紙帶計算物體運動的速度。2、掌握驗證機械能守恒定律的實驗原理。
人教版新課標高中物理必修2向心加速度說課稿
d．某物體沿直線向東運動，原來的速度是5m/s，2s后速度減小到3m/s，求2s內物體速度變化。④如何探究物體作勻速圓周運動時，在Δt時間內的速度變化？分析：有了同一直線上速度變化的鋪墊后，討論物體做勻速圓周運動速度的變化就比較自然了，為了給向心加速度方向的學習打好基礎，可以通過小組協(xié)作，進一步完成下列思考題，使同學們認識到：時間間隔起短，速度變化的方向起接近半徑方向。（多媒體屏幕投影）a．物體沿半徑為1m的軌道做勻速圓周運動，線速度大小為，求1s內物體速度變化并畫出1s內速度變化的示意圖。b．分別求出上題中物體在0.5s、0.25s內速度變化并畫出相應的示意圖。由于沒有辦法直接利用實驗來驗證速度變化的方向，所以，我們采用提供思考題的方法，引導同學在合作學習、自主探究中完成。有了速度變化的研究為鋪墊，加速度的方向問題就迎刃而解了。
人教版新課標高中物理必修2行星的運動說課稿
一、教材分析行星的運動選自人教版普通高中物理必修2第六章第1節(jié)。本節(jié)教學既是前面《運動的描述》和《曲線運動》內容的進一步的延伸和拓展，又能為后面學習萬有引力定律做鋪墊。在本章中占有較為重要的地位，具有承前啟后的作用。同時該節(jié)內容也涉及大量物理史實、貼近學生生活和聯(lián)系社會實際的事實，可進一步培育學生的科學情感、精神和發(fā)展觀。（一）教學目標 1．知識與技能（1）知道地心說和日心說的基本內容。（2.）掌握理解開普勒三大定律的內容，并能應用。（3）理解人們對行星運動的認識過程是漫長復雜的，真理是來之不易的。2．過程與方法通過托勒密、哥白尼、第谷·布拉赫、開普勒等幾位科學家對行星運動的不同認識，了解人類認識事物本質的曲折性并加深對行星運動的理解。3．情感、態(tài)度與價值觀（1）澄清對天體運動神秘、模糊的認識，掌握人類認識自然規(guī)律的科學方法。（2）感悟科學是人類進步不竭的動力。
人教版高中生物必修2基因指導蛋白質的合成說課稿
六、說教學反思由于本節(jié)內容抽象復雜, 插圖多, 涉及的物質種類也比較多，應要求學生做好課前預習。教學中，在處理主干知識和側枝內容的關系時，要做到合理分配時間，明確不同內容的教學要求。教師要注意將知識及時進行歸納、比較和總結。要讓學生了解各個知識點間的內在關系，又要能簡潔、清晰地概述轉錄和翻譯的過程。教師在備課時，一定要仔細分辨并揣摩插圖所表達的意思，并能將不同的插圖內容與教學流程有機地結合起來。在對插圖的處理上，還應分清主次和輕重。教材在呈現(xiàn)教學內容時，采用圖文并茂的方式來揭示轉錄與翻譯的動態(tài)過程。因此，教師不僅要利用插圖達到形象和直觀的教學效果，還應配合教材中的文字描述作深入淺出的講解，使文字信息與圖形信息結合起來，讓學生感知到基因的表達是一個多層次的、動態(tài)的、相互協(xié)調和配合的過程。盡可能利用多媒體課件進行教學。多媒體課件可以形象、生動地反映基因表達的過程，這是紙質教材難以做到的。
人教版高中生物必修2現(xiàn)代生物進化理論的主要內容說課稿
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。學生初步理解隔離的概念之后，可以安排學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。最后教師應強調，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。關于“共同進化與生物多樣性的形成”內容的教學，可以學生自學為基礎，教師提出一些具有啟發(fā)性的問題，師生共同歸納總結的方式推進教學過程。使學生理解共同進化的含義，無機環(huán)境的變化、無機環(huán)境的復雜化和多樣化、有性生殖的出現(xiàn)和生態(tài)系統(tǒng)結構的復雜化和多樣化對生物多樣性形成的作用。最后，組織學生討論生物進化理論在發(fā)展。
人教版高中生物必修2現(xiàn)代生物進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)代生物進化理論.生物進化理論的發(fā)展和其他科學理論的發(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,深入和擴展.從拉馬克的進化學說到達爾文的自然選擇學說,以及現(xiàn)代進化理論的由來,大體都走過了這樣的軌跡.這些應該成為處理本節(jié)教學內容的基本脈絡.本節(jié)內容包括:拉馬克的進化學說,達爾文的自然選擇學說和達爾文以后生物進化理論的發(fā)展,其中重點是達爾文的自然選擇學說.生物進化論不僅是生物學中具有重要地位的基礎理論,也是對人們的自然觀和世界觀有著重要影響的理論.學生通過本章內容的學習,不僅可以了解生物進化理論在達爾文之后的發(fā)展,進一步樹立生物進化的觀點和辯證唯物主義觀點,而且能夠通過學習進化理論的發(fā)展過程,加深對科學本質的理解和感悟.
人教版高中生物必修2雜交育種與誘變育種說課稿
二、誘變育種1、創(chuàng)設情境，引出課題 出示教具或圖片：一穗具有黃粒性狀的玉米。問題：怎樣利用現(xiàn)有的玉米品種培育出具有黑色性狀的玉米新品種呢？2、閱讀資料、討論研究 課前布置興趣小組同學搜集有關航天誘變育種的資料，并在此基礎上進行整理。這樣可以培養(yǎng)學生搜集并且整理資料的能力，并體會科學技術與人們生產生活的密切聯(lián)系。 學生閱讀生物興趣小組課前搜集的有關航天誘變育種問題的資料及教材P100得內容。以小組為單位討論回答有關誘變育種的有關問題，附：設置的問題：1、 新品種中有沒有產生新基因？2、空中誘發(fā)基因突變的條件有哪些？3、航天誘變育種有哪些優(yōu)點？4、地面上有哪些因素可以誘發(fā)生物體產生基因突變？5、誘變育種有哪些局限性？如何克服？以航天誘變育種為典型，解決誘變育種過程中遇到的相關問題。讓學生學會對已有知識進行應用。3、歸納總結，形成體系 通過以小組為單位的表達和交流，師生共同總結歸納，形成有關誘變育種的知識體系，提升學生對于知識的理解。
人教版高中政治必修2參與政治生活的基礎和準則說課稿
觀點一：沒有無義務的權利，也沒有無權利的義務；觀點二權利與義務是完全對等的。根據(jù)學生的回答，教師點撥歸納，一般來說，權利與義務是對等的，因為沒有義務的權利只能是特權，而沒有權利的義務只能是奴役，只有將權利與義務有機結合起來，才能構成一個符合社會發(fā)展要求的公民社會，在討論和思考中，使學生樹立正確的觀點，引導學生多方面、多角度地辯證認識權利與義務的關系。（3）個人利益和國家利益相結合的原則。引出汶川大地震中一些先進人物事跡，但另外也有一些人發(fā)國難財?shù)娜?，如黑心棉事件等，針對上述材料，請同學們談談自己的看法。引導學生理解國家和公民個人利益在根本上是一致的，當個人利益與國家利益發(fā)生矛盾時，個人利益要服從國家利益。通過案例分析，培養(yǎng)學生獲取信息的能力，自主學習的能力以及全面看問題的能力，再結合教師的講授，給學生一種茅塞頓開的感覺。

人教版高中地理必修2第三章第一節(jié)農業(yè)的區(qū)位選擇說課稿
◆設計意圖：培養(yǎng)學生獨立思考、合作學習的能力。分別說明市場、交通、勞動力、機械和政策對農業(yè)生產的影響，讓學生切實地考慮，拓展學生思路。教師激發(fā)和維持學生學習動機、引導學生、幫助學生自主發(fā)現(xiàn)、探索知識，達到鞏固所學知識，檢驗學生的實踐應用能力。D.分析教材，識別圖片，理解農業(yè)地域閱讀、分析教材，看圖識別，研究案例《澳大利亞地混合農業(yè)生產》、思考問題、解決問題◆設計意圖：圖片展示能清楚直觀地說明問題，通過案例分析，了解澳大利亞的混合農業(yè)生產，培養(yǎng)學生獨立思考問題、解決問題的能力，開拓學生思路。3．課堂小結：◆設計意圖：幫助學生回顧課堂、鞏固所學知識。4.反饋練習：◆設計意圖：知識與能力強化訓練，鞏固本課所學知識，提高應用能力。
人教版高中地理必修2南京的自行車是多了還是少了說課稿
在學生回答的基礎上進行歸納小結：發(fā)展城市公共交通? 明確道路分工? 合理規(guī)劃停車場? 減少出行距離? 錯開出行高峰? 加大城市道路建設? 進行科學合理的交通管理，重視智能交通系統(tǒng)的建設提問：這組同學在幻燈片中提到城市環(huán)境污染源主要有哪些？城市交通環(huán)境問題除了交通工具的尾氣排放帶來大氣污染外，還會給城市環(huán)境帶來什么問題？這組同學基本同意自行車多是加劇南京空氣污染的間接原因，你同意他們的觀點嗎？在學生回答的基礎上，教師進行歸納小結：自行車是一種綠色交通工具，既環(huán)保又經濟。只有當它在某些機動車和非機動車不分的地段，影響車輛行駛速度的時候，它才可能成為加劇空氣污染的間接原因。那么我們針對交通工具對環(huán)境造成的影響，除了這組同學提到的三點解決措施以外，我們還有什么要補充的解決方法嗎？

The themes of this part are “Talk about how to become an astronaut” and “Talk about life in space”. As Neil Armstrong said “Mystery creates wonder and wonder is the basis of man’s desire to understand. Space is difficult for human to reach, therefore, humans are full of wonders about it. However, if wanting to achieve the dream of reaching the Moon, some of our human should work hard to be an astronaut at first. Part A(Talk about how to become an astronaut) is a radio interview in a radio studio, where the host asked the Chinese astronauts about his story how to become an astronaut. Yang Liwei told his dreamed to be an astronaut since childhood. Then he worked hard to get into college at 22. The next 10 years, he gradually became an experienced pilot. At the same time, to be an astronaut, he had to study hard English, science and astronomy and trained hard to keep in good physical and mental health and to practise using space equipment. Part B (Talk about life in space) is also an interview with the astronaut Brown, who is back on the earth. The host Max asked about his space life, such as his emotion about going back the earth, the eating, shower, brushing, hobbies and his work. Part A and Part B are interviews. So expressing curiosity about the guests’ past life is a communicative skill, which students should be guided to learn.1. Students can get detailed information about how Yang Liwei became an astronaut and Max’s space life.2. Students learn to proper listening strategy to get detailed information---listening for numbers and taking notes.3. Students can learn related sentences or phrases to express their curiosity like “ I wish to know...” “I’d love to know...”4. Students can learn more about the space and astronauts, even be interested in working hard to be an astronaut
