My students are in senior high students. They have learnt English for many years, they’ve known many words and sentences, but their speaking and reading abilities are still not very good. So I will practice their speaking and reading abilities through different exercises.According to the New Standard Curriculum and the present situation, I set the teaching aims as follows: firstly, knowledge aims. Students can grasp some new words, such as worthwhile, move off. Moreover, students can understand the content of the passage and get familiar with the topic of studying chimps in wildlife. Secondly, ability aims. Students can use reading strategies such as skimming and scanning in reading process. Thirdly, emotional aims.

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2羅斯福新政說課稿2篇
1、教材的地位作用本課是新人教版普通高中歷史必修Ⅱ第六單元第18課的內容，闡述羅斯福新政的背景、措施、影響。從單元知識安排看，本課與第17課《空前嚴重的資本主義世界經濟危機》、19課《戰(zhàn)后資本主義的新變化》共同詮釋第六單元課題——《資本主義世界經濟政策的調整》。說明了“資本主義經濟理論和政策隨著資本主義發(fā)展而不斷調整的特點”,凸顯了“市場調節(jié)”和“國家干預”在經濟發(fā)展中的重要性。從知識體系看，它是學生學習了第一次工業(yè)革命后自由資本主義、第二次工業(yè)革命后的壟斷資本主義等之后出現的，既是對上述知識的鞏固與綜合運用，又為學生學習必修二的相關內容打下基礎，有承上啟下的作用。本課三個子目從邏輯上看又是遞進關系。第一個子目“臨危受命”承上啟下，說明了羅斯福上臺的歷史背景具有臨危受命的特點，第二個子目“實施新政”講述了羅斯福新政的主要內容，第三個子目“擺托危機困境”主要講述了羅斯福新政的影響。

(2).教學手段為了使我根據教材而設計的三個教學目標以及重點難點得以的突出和突破,達到最大化的展示境界,同時也為了配合以上我選擇的四種教法得以完滿實現,我決定采用“多媒體”教學手段進行全程教學。利用電腦的信息容量大,操作簡便等優(yōu)點,形象生動的直觀展示教學內容,不但提高學習效率和質量,而且容易激發(fā)學生的學習興趣和調動學習的積極性。四、說學法我為學生設計了三個學習方法：1.讓學生學會在探究中學。通過“對黑人嚴酷處境的探究”和對文中重點語句的探究,培養(yǎng)學生在探究中學習的能力。2.讓學生學會在讀中學。通過“誦讀法”指導學生在誦讀過程中感受演講詞內在的魅力,學會在讀中學。3.讓學生學會在練習中學。通過“課外延伸練習法”,對所學的知識進行運用,培養(yǎng)學生的創(chuàng)新和自學能力。

觀察實驗視頻實驗驗證師：其實大家完全可以利用身邊的器材來驗證。實驗1、用彈簧秤掛上鉤碼，然后迅速上提和迅速下放?，F象：在鉤碼被迅速上提的一瞬間，彈簧秤讀數突然變大；在鉤碼被迅速下放的一瞬間，彈簧秤讀數突然變小。師：迅速上提時彈簧秤示數變大是超重還是失重？迅速下放時彈簧秤示數變小是超重還是失重？生：迅速上提超重，迅速下放失重。體會為何用彈簧秤測物體重力時要保證在豎直方向且保持靜止或勻速實驗2、學生站在醫(yī)用體重計上，觀察下蹲和站起時秤的示數如何變化？在實驗前先讓同學們理論思考示數會如何變化再去驗證，最后再思考。（1）在上升過程中可分為兩個階段：加速上升、減速上升；下蹲過程中也可分為兩個階段：加速下降、減速下降。（2）當學生加速上升和減速下降時會出現超重現象；當學生加速下降和減速上升時會出現失重現象；（3）出現超重現象時加速度方向向上，出現失重現象時加速度方向向下。完全失重
中班社會《不和陌生人走》說課稿
2、活動既符合幼兒的年齡特點又對幼兒具有一定的挑戰(zhàn)性。中班幼兒已有一定的語言基礎，思維和表達能力也有了相應發(fā)展，這樣可以讓幼兒結合生活經驗自由表達自己對陌生人的認識，而如何辨別陌生人的善于惡，靈活應對陌生人的來訪又對幼兒的社會交往智能是一個考驗。3、對幼兒實施自我保護的教育符合《綱要》精神?！毒V要》中指出：“幼兒應知道必要的安全保健常識，學習保護自己。二、說教材現實生活中一些不法分子以哄騙為手段拐賣兒童，他們的罪惡行徑給孩子的身心造成巨大摧殘，使許多家庭沉浸在失去孩子的痛苦中，給社會也帶來極大的危害。在公安機關追蹤調查的同時，我們教師從教育角度著手讓孩子學會自己保護自己，從某種程度上加強了幼兒的保護力度。選取《不跟陌生人走》開展活動三、說活動目標1、（認知目標）引導幼兒了解一些自我保護的常識，知道不能輕信陌生人的話，不跟陌生人走。2、（情感目標）樹立初步的防范意識。3、（能力目標）培養(yǎng)幼兒思考問題、解決問題的能力。四、說重點難點活動重點：樹立防范意識，學習自我保護的方法。（第三環(huán)節(jié)）活動難點：培養(yǎng)幼兒思考問題、解決問題的能力。（第四環(huán)節(jié)）
高中思想政治人教版必修三《文化創(chuàng)新的途徑》說課稿
二、說學情本課的教學對象為高二學生，他們思維活躍已具備一定歸納能力和分析、綜合能力，能夠自主地分析現實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行指導，以免走入誤區(qū)。三、教學目標根據新課程標準、教材特點、學生的實際，我確定了如下教學目標：【知識與能力目標】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。
人教版新課標高中物理必修2探究彈性勢能的表達式說課稿4篇
設疑自探：一個壓縮或拉伸的彈簧就是一個“儲能器”，怎樣衡量形變彈簧蘊含能量的多少呢？彈簧的彈性勢能的表達式可能與那幾個物理量有關？類比：物體的重力勢能與物體所受的重力和高度有關。那么彈簧的彈性勢能可能與所受彈力的大小和在彈力方向上的位置變化有關，而由F=kl知彈簧所受彈力等于彈簧的勁度系數與形變量的乘積。預測：彈簧的彈性勢能與彈簧的勁度系數和形變量有關。學生討論如何設計實驗： ①、用同一根彈簧在幾次被壓縮量不同時釋放（勁度系數相同，改變形變量），觀察小車被彈開的情況。②、分別用兩根彈簧在被壓縮量相同時釋放（形變量相同，勁度系數不同），觀察小車被彈開的情況。交流探究結果：彈性勢能隨彈簧形變量增大而增大。隨彈簧的勁度系數的增大而增大。
人教版高中地理必修2第六章第二節(jié)中國的可持續(xù)發(fā)展實踐說課稿
1．導入新課：用觸目精心的一首MTV《EARTHSONG》導入新課，引出人類已經面臨嚴峻的人口、資源與環(huán)境的危機。而中國是世界上人口最龐大的國家，人口、資源與環(huán)境問題更加嚴重。既然我們知道了可持續(xù)發(fā)展的概況，了解了它的發(fā)展過程，從上節(jié)課內容的分析中，也理解了作為人類的發(fā)展，可持續(xù)是唯一的選擇，也是我們所追求的目標，那么，具體到我們國家、我們周圍的生產、生活情況又該如何呢?2.新課講授：首先，通過三則補充材料的案例和課本上的內容分別說明龐大的人口壓力，資源短缺和不合理利用，深刻的環(huán)境危機方面的問題，得出走可持續(xù)發(fā)展之路是我國的必然的唯一的選擇。接著通過《中國21世紀議程》——中國21世紀人口環(huán)境與發(fā)展的白皮書的過渡引出實施可持續(xù)發(fā)展的途徑。在這部分內容的講解上，主要通過其中一種主要途徑-循環(huán)經濟的講解，特別是對清潔生產和生態(tài)農業(yè)的具體分析，總結出中國走可持續(xù)發(fā)展之路事在必行，行必有果。再通過完成課本上最后一個活動題對本節(jié)內容進行深化。
人教版高中生物必修3第四章第二節(jié)《種群數量的變化》說課稿
4、種群數量變化的其他類型我結合“種群數量下降”這個知識點對學生進行寓教?，F今的自然界，許多野生生物種群的數量都在下降，為什么呢？我提供了世界人口近2000年的種群增長曲線，一切都在不言而喻中?，F今社會的主題是呼吁建立和諧社會，作為生物老師，我想它不應該僅僅指人與人之間的和諧，也不應該僅僅指人與社會之間的和諧，它更應該昭示著人與自然之間的和諧，人類只有學會與自然和諧相處，才能在生物圈中享受最大的幸福。6、小結課程在實驗的大背景下展開，也在實驗的背景中結束，這里可以呈現出一個完整的探究思路。同時，學生思考如何實現多種預期過程，相當于對本課進行小結。五、效果預測課堂上選取的內容基于學生的生活體驗，創(chuàng)設的情境能激發(fā)學生的興趣，設置的問題符合學生的認知水平，有助于學生能力的提高，教學目標可以基本實現。

為使學生對知識達到深化理解、鞏固提高的效果，我結合兩個討論題專門設計了一組即時訓練題，做完后，屏幕展示匯總，以及時鞏固新知。然后，進行當堂訓練，這部分習題分AB兩個層次，適合不同能力的學生做，做完后收上，課后批改后會了解學生掌握的情況，從而得到準確的學習信息。這部分用時約6分鐘。三）結課組織學生總結本節(jié)課。引導學生可對照教學目標總結知識，從而盡快將知識形成能力；也可總結方法，從而理解生物學分析思路；還可以談談感想，從而理解人與自然的和諧相處的必要性。最后要求學生完成課后習題，課后時間允許的話還可組織有興趣的同學進行對當地農田生態(tài)系統(tǒng)的能量流動情況得調查。這部分用時大約4分鐘。七說板書設計生態(tài)系統(tǒng)的能量流動一概念:生態(tài)系統(tǒng)中能量的輸入,傳遞和散失過程
