人教版高中生物必修3第四章第二節(jié)《種群數(shù)量的變化》說課稿
4、種群數(shù)量變化的其他類型我結(jié)合“種群數(shù)量下降”這個知識點對學生進行寓教?，F(xiàn)今的自然界，許多野生生物種群的數(shù)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(xiàn)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(yīng)該僅僅指人與人之間的和諧，也不應(yīng)該僅僅指人與社會之間的和諧，它更應(yīng)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(jié)課程在實驗的大背景下展開，也在實驗的背景中結(jié)束，這里可以呈現(xiàn)出一個完整的探究思路。同時，學生思考如何實現(xiàn)多種預(yù)期過程，相當于對本課進行小結(jié)。五、效果預(yù)測課堂上選取的內(nèi)容基于學生的生活體驗，創(chuàng)設(shè)的情境能激發(fā)學生的興趣，設(shè)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(xiàn)。
人教版高中生物必修3第六章第二節(jié)《保護我們共同的家園》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)達國家（如美國、加拿大和歐盟國家等），拒絕核準或遲遲不予核準該議定書。主要爭議的問題是，這些國家擔心影響本國經(jīng)濟的發(fā)展和其他國家可能不承擔相應(yīng)的責任。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)濟發(fā)展”和“發(fā)展中國家也應(yīng)該承擔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)達國家率先核準《京都議定書》（我國政府早在2002年9月就核準了《京都議定書》）。
人教版高中生物必修3第一章第二節(jié)《內(nèi)環(huán)境穩(wěn)態(tài)的重要性》說課稿
四、穩(wěn)態(tài)的重要意義 為什么內(nèi)環(huán)境穩(wěn)態(tài)失調(diào)后，會對機體造成危害？引導學生從細胞代謝需要的物質(zhì)和條件進行分析，最后總結(jié)出：內(nèi)環(huán)境穩(wěn)態(tài)是機體進行正常生命活動的必要條件。如何預(yù)防內(nèi)環(huán)境穩(wěn)態(tài)失調(diào)、保持機體健康？引導學生從外界環(huán)境和機體自身調(diào)節(jié)能力兩個方面去思考。即通過加強自我保健，減少外界環(huán)境變化對機體的不良影響，同時增強機體的調(diào)節(jié)能力以適應(yīng)多變的外界環(huán)境。具體如何做？學生討論，總結(jié)。1.保護我們的生存環(huán)境，防治環(huán)境污染。2.加強體育鍛煉，增強體質(zhì)，提高機體適應(yīng)外界環(huán)境的能力。3.加強自我保健，為機體保持健康創(chuàng)造有利條件。尤其是處于比較惡劣的工作環(huán)境中的人，更應(yīng)注意自身保健，如邊防戰(zhàn)士注意保暖、煉鋼工人注意降溫、抗洪戰(zhàn)士注意補充水鹽等。了解這些知識后才能懂得如何關(guān)愛自身和他人。
人教版高中生物必修3第二章第一節(jié)《通過神經(jīng)系統(tǒng)的調(diào)節(jié)》說課稿
3、總結(jié)(這部分要5分鐘)學生在教師的提示和問題的引導下，完成對本節(jié)課的知識的歸納和小結(jié)。利用簡煉、清晰的語言，再一次的突出本節(jié)課的重點，起到畫龍點睛的作用，培養(yǎng)了學生的表達能力。4、鞏固練習(這部分要10分鐘)用大屏幕投影把題目投影在屏幕上，讓學生思考，然后回答。這部分安排10分鐘的時間，讓學生思考完成具有針對性的練習，進行知識鞏固和教學效果反饋，及時糾正錯誤的理解和片面的認識。5、板書設(shè)計在板書中,我根據(jù)板書的“規(guī)范、工整和美觀”的要求，結(jié)合所學的內(nèi)容，設(shè)計了如圖所示的板書。在其中，注重了重、難點的突出，使學生對知識的結(jié)構(gòu)、層次、重點、難點一目了然，便于記憶和理解。四、效果分析對于反射的判斷，學生仍有可能出現(xiàn)錯誤，如刺激坐骨神經(jīng)肌肉的收縮，教師應(yīng)強調(diào)沒有完整的反射弧結(jié)構(gòu)參與的不是反射。
人教版高中生物必修3第三章第二節(jié)《生長素的生理作用》說課稿
強調(diào)重力對生長素分布的影響，為下面的內(nèi)容講解做鋪墊，明確植物出現(xiàn)向光性與生長素分布不均有關(guān)。復(fù)習舊知識，產(chǎn)生首因效應(yīng)，鞏固和加強記憶。通過植物向光性是生長素分布較多而促進生長，進而提出“對于植物來說，生長素是不是越多越好”這個問題，引發(fā)思考，鍛煉思維。說明生長素濃度對不同器官產(chǎn)生的影響不同，讓學生對這一情況有一個整體印象。結(jié)合數(shù)學知識逐步分析圖上各點和各曲線的含義，引導學生得出不同器官對生長素濃度的敏感性順序，為解釋橫放植物“S”型生長做鋪墊。通過對曲線的分析，得出低生長素濃度起促進作用，高濃度有抑制作用這種雙重性，并得出其雙重性表現(xiàn)。通過以上的分析和總結(jié)，對橫放植物“S”型生長進行解釋，達到首尾呼應(yīng)的效果。采用“蒙太奇”手法，引申到“太空中，橫放植物將會如何生長”這個問題，引發(fā)學生的聯(lián)想和思考，以這種提問方式結(jié)課為下節(jié)課的開課做了鋪墊，掌握了主動權(quán)。
人教版高中生物必修3第五章第二節(jié)《生態(tài)系統(tǒng)的能量流動》說課稿
為使學生對知識達到深化理解、鞏固提高的效果，我結(jié)合兩個討論題專門設(shè)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(jié)課組織學生總結(jié)本節(jié)課。引導學生可對照教學目標總結(jié)知識，從而盡快將知識形成能力；也可總結(jié)方法，從而理解生物學分析思路；還可以談?wù)劯邢?，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?shù)剞r(nóng)田生態(tài)系統(tǒng)的能量流動情況得調(diào)查。這部分用時大約4分鐘。七說板書設(shè)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

一、說教材本節(jié)課選自于人教版語文必修二第二單元詩三首中的一首詩歌，它是陶淵明歸隱后的作品。寫的是田園之樂，實際表明的是作者不愿與世俗同流合污的心聲，甘愿守著自己的拙志回歸田園。學習該詩，有助于學生了解山水田園詩的特點，感受者作者不同流俗的高尚情操，同時可以培養(yǎng)學生初步的鑒賞古典詩歌的能力。
人教版高中語文必修3《宇宙的邊疆》說課稿2篇
（有的恒星旋轉(zhuǎn)平穩(wěn)均衡，有些恒星是因快速旋轉(zhuǎn)而變了形。作者以擬人的手法，生動形象地描述，仿佛向我們展示了不同恒星的性情：有的穩(wěn)重沉靜，有的急切躁動。讀來生動有趣，妙趣橫生。）(3)我們探索宇宙的時候，既要勇于懷疑，又要富于想象。想象經(jīng)常能夠把我們帶領(lǐng)到嶄新的世界，沒有想象，我們就處處碰壁。懷疑可以使我們擺脫幻想，還可以檢驗我們的推測。（對于未知領(lǐng)域的探索是需要懷疑和想象的，想象是科學的翅膀，敢于想象，并不斷地探索驗證，所謂“大膽假設(shè)，小心求證”懷疑否定舊知，產(chǎn)生新知。作者以簡潔的語言闡述了想象和懷疑看似矛盾的兩者在宇宙探索中的相輔相成，和諧統(tǒng)一。作者不囿于介紹宇宙知識，還發(fā)表自己的見解。）(4)我認為宇宙里很可能到處都充滿著生命，只是我們?nèi)祟惿形窗l(fā)現(xiàn)而已。我們的探索才剛剛開始。
人教版高中語文必修1《優(yōu)美的漢字》說課稿
明確：（1）結(jié)繩記事說。原始記事的一種方法。人類在沒有發(fā)明文字或文字使用尚不普遍時，常用在繩索或類似物件上打結(jié)的方法記錄數(shù)字，表達某種意思，用以傳達信息，處理事件。 （2）書畫說。（3）倉頡造字說。中國自古就有倉頡造字之說。文字的發(fā)明是人類發(fā)展史上一件石破天驚的大事，它將人們的思維、語言、經(jīng)驗以及復(fù)雜的社會現(xiàn)象記錄下來，使文化得以傳播交流、世代傳承。2、漢字的形體：中華民族五千年的歷史中，漢字的演變，從甲骨文－－金文－－大篆－－小篆－－隸書－－草書－－楷書－－行書，字形由象形到點橫豎撇捺的方塊字，經(jīng)歷了漫長的歲月。其中凝聚著民族的智慧，也體現(xiàn)出漢字逐步完善的過程，凸顯其方方正正、四平八穩(wěn)的特點。漢字又是一種文化的體現(xiàn)，那些經(jīng)過藝術(shù)處理的漢字或跳起了拉丁舞、有的如同酒醉的成龍打起了醉拳，更是讓我們感到的是在欣賞漢字在紙張上跳舞，所以：書法是“紙上的舞蹈”。請大家看到書上的相關(guān)內(nèi)容，注意每一種形體的漢字的載體是什么，其功能又有什么不一樣。
人教版高中語文必修2《故都的秋》說課稿3篇
請一位朗誦水平較好的學生，有感情的朗讀課文12自然段，其他同學完成一項任務(wù)：這一段可否去掉？為什么？學生思考、圈畫、交流、討論，然后小組發(fā)言，其他小組補充，教師從旁予以點撥，引導學生進一步明確作者的思想情感。明確：作者要創(chuàng)造一種文化氛圍，于自然氣息之外再添一重文化氣息，與“故都”題旨暗合。從行文章法上看，這里是宕開文筆，縱橫議論，顯出深厚的文化底蘊和開闊的思路。這一段采用議論，通過古今中外的引證，說明感秋處處有，中國文人最突出，而秋“深味”非在中國北方莫屬，這其實還是為了突出故都之秋。（設(shè)計意圖：提高學生探究的能力，充分把握本文的教學內(nèi)容，深刻體悟作者的情感，了解作者對秋的禮贊情感，從而突破教學難點。）
豐富的圖形世界 展開與折疊教案教學設(shè)計
設(shè)計意圖：題目1是判斷能否折疊形成立體幾何，本題可以研究學生對常見幾何體的把握是否成熟。題目2是考察正方體的展開圖，一方面可以研究學生對幾何體的把握，另一方面可以引導學生思考，引出下面要學習的內(nèi)容。）學生預(yù)設(shè)回答：題目一：學生應(yīng)該很容易的說出折疊后形成的立體圖形。題目二：①運用動手操作的方法，剪出題目中的圖形，折疊后對題目做出判斷。 ②利用空間觀念，復(fù)原展開圖，發(fā)現(xiàn)6的對面是1，2的對面是4，5的對面是3，進而做出判斷。教師引導語預(yù)設(shè)：① 當學生運用動手操作的方法，可以讓學生動手實踐一下，下一步再引導學生觀察正方體，發(fā)現(xiàn)規(guī)律。② 當學生運用空間觀念，教師要放慢語調(diào)，和學生一起想象，鍛煉學生空間想象能力。
人教版高中歷史必修2古代的經(jīng)濟政策說課稿
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，從而阻斷了中國學習西方的先進科學技術(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世紀中國顯露出哪些危機？

Good morning, distinguished judges:It’s my honor to talk about my teaching ideas with you. Today my topic is Women of Achievement. My presentation consists of six parts: the analysis of teaching material and student, teaching aims, key and difficult points, teaching and studying method, teaching procedures and blackboard design.First, let’s focus on the analysis of teaching material. This lesson is from New Senior English for China Student’s Book 4 Unit 1, the reading part. The main topic of the passage is the introduction of a student of Africanwildlife. After this lesson, the students will learn more information about her studying chimps in Africa, and their reading and speaking abilities can be developed as well.The next part is the analysis of students. 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. Students can have the awareness of protecting animals and care about animals.Based on the above analysis, the key point of this lesson is to get the main idea and the detailed information from the passage; the difficult point is to talk about the wildlife protection and use reading strategies.
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
