人教版高中語文必修2《短歌行》說課稿2篇
一、說教材《短歌行》是普通高中課程標(biāo)準(zhǔn)實(shí)驗(yàn)教科書必修（二）第二單元的一篇略讀課文，本單元安排的是先秦到南北朝時期的詩歌?！抖谈栊小肥侵渭?、軍事家、文學(xué)家曹操的作品。詩中抓住“憂”字來寫詩人為什么“憂”，如何解“憂”，從而表達(dá)希望能夠招攬人才、完成統(tǒng)一天下的雄心壯志。所以本單元安排《短歌行》一詩，對學(xué)生全面了解曹操，感受曹操在短暫的人生中竭力創(chuàng)造偉業(yè)的氣概。二、說學(xué)生我這一課的教學(xué)對象是高一學(xué)生。他們進(jìn)入高中學(xué)習(xí)的時間只有三個多月，現(xiàn)在已經(jīng)完成了必修（一）的學(xué)習(xí)。學(xué)習(xí)了現(xiàn)代詩歌單元，有了一定的詩歌學(xué)習(xí)基礎(chǔ)，初步掌握了讀詩的基本方法，但是還未能形成成熟的穩(wěn)定的學(xué)習(xí)方式。同時，本單元學(xué)習(xí)是高中第一次接觸古代詩歌，詩歌語言上的障礙和時間上的跨度對他們來說都是學(xué)習(xí)上的困難。因此教師要引導(dǎo)學(xué)生自主學(xué)習(xí)，合作學(xué)習(xí)，為他們設(shè)置新的學(xué)習(xí)情境，提供合作探究的機(jī)會。

通過寫文章梗概，培養(yǎng)學(xué)生綜合運(yùn)用語言的能力，學(xué)習(xí)用恰當(dāng)?shù)挠⒄Z描述科學(xué)家的故事。這是本課的教學(xué)難點(diǎn)。教師可以使用完形填空的方式來幫助學(xué)生整理語篇，從而來降低難度。本課的教學(xué)重點(diǎn)的突破方法是：在閱讀前，讓學(xué)生初步了解得出科學(xué)觀點(diǎn)所需要的基本程序，從而輕松而自然地導(dǎo)入文章的閱讀；在閱讀過程中，由易到難設(shè)計(jì)快速閱讀和精讀的問題，層層推進(jìn)各種閱讀活動，讓學(xué)生對閱讀內(nèi)容從整體感知到細(xì)節(jié)理解，最后深層讀懂整篇文章，同時加強(qiáng)閱讀策略的指導(dǎo)，讓每個學(xué)生都主動參與課堂教學(xué)活動，最終達(dá)到提高閱讀能力的目的。Step 4 Post-readingGroup Activities四人小組共同合作，在老師的適當(dāng)指導(dǎo)下，就以下2個問題展開討論，讓學(xué)生就所知、所學(xué)、所感和所想融入話題，然后抽若干同學(xué)代表作小組發(fā)言。1.

人教版高中英語必修5Making the news說課稿4篇
今天我們來介紹一下必修五第四單元的授課方式。這個單元的題目是Making the news。應(yīng)該是學(xué)生比較感興趣的話題，學(xué)生往往對新聞工作充滿好奇，所以我們可以利用這個機(jī)會多設(shè)計(jì)一些師生互動和學(xué)生互動，來激發(fā)起學(xué)習(xí)的積極性，提高學(xué)習(xí)效率。同時我們可以利用這個單元不僅幫助學(xué)生掌握語言知識，培養(yǎng)語言能力，同時讓其了解新聞工作的重要性，培養(yǎng)起社會智能感。這個單元分為六個課時，它的教學(xué)目標(biāo)是這樣的：語言目標(biāo)是掌握詞匯表中的常用單詞和短語，掌握倒裝句的一些基本用法。 技能目標(biāo)是能初步掌握約會的基本句型并在真實(shí)的場景下正確運(yùn)用。新聞報道類文章的寫作技能。采訪的基本規(guī)范和溝通技能。情感目標(biāo)是對新聞報道的客觀性和真實(shí)性有更好的理解。對新聞記者的職業(yè)有更深入的了解，并能體會其工作的重要性。下面我們來介紹一下第一課時的授課方式，第一課的教學(xué)目標(biāo)是這樣的第一課時的教學(xué)目標(biāo)語言目標(biāo):單詞：Occupation, journalist, editor, photographer, curious, personality, enthusiasm
人教版高中政治必修3聚焦文化競爭力說課稿
（1）文化與經(jīng)濟(jì)、政治在經(jīng)濟(jì)基礎(chǔ)上相互影響。①經(jīng)濟(jì)、政治和文化是社會生活的三個基本領(lǐng)域。其中，經(jīng)濟(jì)是基礎(chǔ)，政治是經(jīng)濟(jì)的集中表現(xiàn)，文化是經(jīng)濟(jì)和政治的反映。一定的文化由一定的經(jīng)濟(jì)、政治所決定，又反作用于一定的政治、經(jīng)濟(jì)，給予政治、經(jīng)濟(jì)以重大影響。②經(jīng)濟(jì)發(fā)展是文化發(fā)展的基礎(chǔ)。但這并不意味著文化的發(fā)展始終與經(jīng)濟(jì)的發(fā)展亦步亦趨。如同不能簡單地把精神文明看作是物質(zhì)文明的派生物和附屬品一樣，也不能簡單地認(rèn)為文化是經(jīng)濟(jì)、政治的派生物和附屬品。文化有其自身的傳承性和相對的獨(dú)立性。那種認(rèn)為只要物質(zhì)條件好了，精神文化自然而然地就會好起來，物質(zhì)條件差一點(diǎn)，精神文化就不可能搞好的觀點(diǎn)，不符合歷史發(fā)展的事實(shí)，是不正確的。③掀開歷史的畫卷，文化既有古今和地域之別，又有先進(jìn)與落后、腐朽之分。不同的文化，對經(jīng)濟(jì)、政治的影響不同，對社會發(fā)展的作用也不同。不同民族的文化，影響不同民族和國家各具特色的發(fā)展道路。
人教版高中生物必修3第三章第一節(jié)《植物生長素的發(fā)現(xiàn)》說課稿
（5）根據(jù)實(shí)驗(yàn)的第五部分——驗(yàn)證性實(shí)驗(yàn)結(jié)果，證實(shí)了達(dá)爾文關(guān)于植物向光性運(yùn)動原因的假說――確實(shí)存在一種物質(zhì)致使胚芽尖端產(chǎn)生了向光運(yùn)動。這樣通過多個實(shí)驗(yàn)的多媒體演示過程，強(qiáng)化學(xué)生的思維，最終在學(xué)生的大腦中形成科學(xué)研究過程的”條件反射”。為了使學(xué)生初步學(xué)會”設(shè)計(jì)對照實(shí)驗(yàn)的方法”，首先也利用多媒體的演示實(shí)驗(yàn)，并在其中特意設(shè)置一些”陷阱”，通過多次”請學(xué)生進(jìn)入‘陷阱’”，來強(qiáng)化設(shè)計(jì)實(shí)驗(yàn)時應(yīng)該控制的變量問題，從而在學(xué)生的認(rèn)知領(lǐng)域里初步構(gòu)建出設(shè)計(jì)對照實(shí)驗(yàn)的知識體系。3、歸納總結(jié)1934年，荷蘭科學(xué)家郭葛等人從植物中分離出了這種能使植物產(chǎn)生向光性的物質(zhì)，并確定它就是吲哚乙酸。這就真正從化學(xué)物質(zhì)的角度證實(shí)了達(dá)爾文的假設(shè)。在能夠從植物體中分離提取出生長素之后，要想知道：除了能使植物產(chǎn)生向光運(yùn)動之外，生長素對于植物的器官還有什么作用？可以采用哪種方法來進(jìn)行試驗(yàn)？
人教版高中生物必修3第五章第三節(jié)《生態(tài)系統(tǒng)的物質(zhì)循環(huán)》說課稿
步驟四：展示點(diǎn)評、質(zhì)疑探究展示小組展示討論論成果，要求每組B、C層次學(xué)生進(jìn)行展示。展示結(jié)束后由點(diǎn)評同學(xué)對展示結(jié)果進(jìn)行點(diǎn)評，要求先點(diǎn)評對錯；再點(diǎn)評思路方法和應(yīng)注意的問題。既要有結(jié)論，又要有分析，力爭有相關(guān)的總結(jié)和拓展。下面的同學(xué)注意傾聽、思考，關(guān)鍵內(nèi)容做好筆記，有補(bǔ)充或不明白的地方及時、大膽提出，力爭全部過關(guān)，解決疑難點(diǎn)。根據(jù)學(xué)生點(diǎn)評結(jié)果，教師適當(dāng)點(diǎn)評拓展。步驟五：拓展提升、總結(jié)升華簡單扼要的課堂小結(jié)，系統(tǒng)回顧知識，強(qiáng)化學(xué)生對于生態(tài)系統(tǒng)物質(zhì)循環(huán)的認(rèn)識。環(huán)節(jié)三：課后檢測布置訓(xùn)練內(nèi)容，鞏固知識。五、課后反思：本堂課采用我校163高效課堂模式，通過小組合作探究、展示自我、互相點(diǎn)評的方式完成整堂課的教學(xué)內(nèi)容，充分突出了新課標(biāo)中以學(xué)生為主體的指導(dǎo)思想。教學(xué)過程中，依據(jù)學(xué)生的個性差異，提出不同要求，布置不同任務(wù)，讓不同層次的學(xué)生都能參與其中，調(diào)動全體學(xué)生的積極性，促進(jìn)全體學(xué)生的發(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.
人教版高中生物必修1細(xì)胞分化說課稿
在講述細(xì)胞分化的意義時，也可以用實(shí)例來解決，工廠的生產(chǎn)車間里不同的工人干著不同的工作，一件產(chǎn)品的產(chǎn)出需要這些工人才能創(chuàng)造出來，一個生物體就像一個車間一樣，不同的細(xì)胞各司其職，相互合作。工人的分工是主管調(diào)解出來的，而不同細(xì)胞的出現(xiàn)就是細(xì)胞分化的結(jié)果，所以說，細(xì)胞的分化是生物體發(fā)育的基礎(chǔ)。在講到細(xì)胞全能性的時候，要多給學(xué)生舉些關(guān)于細(xì)胞全能性的例子，如植物組織培養(yǎng)、克隆技術(shù)等等，讓學(xué)生從實(shí)際的例子中真正的悟出細(xì)胞全能性的含義。此外，還要重視教材中的疑問，適當(dāng)對題目進(jìn)行引申,使它的作用更加突出，有利于學(xué)生對知識的串聯(lián)、積累、加工，從而達(dá)到舉一反三的效果。怎樣來解釋細(xì)胞的全能性呢？這主要以講授法來解釋了，細(xì)胞全能性的體現(xiàn)需要在組織或器官離體后才能體現(xiàn)出來，每個細(xì)胞都包含著生物體的全套遺傳基因，通過基因選擇性的表達(dá)，使離體的組織或器官通過分裂和分化逐漸發(fā)育成完整的植株。
人教版高中生物必修1細(xì)胞增殖說課稿
f.有絲分裂的意義（討論分析教學(xué)），首先引導(dǎo)學(xué)生結(jié)合所學(xué)知識討論有絲分裂的的作用，最后有教師歸納總結(jié)，并要求學(xué)生在理解的基礎(chǔ)上記憶。g.無絲分裂（圖形直觀教學(xué)、簡介），本部分內(nèi)容不是教學(xué)的重點(diǎn)，內(nèi)容也相對簡單，所以我的教學(xué)方法是直接給學(xué)生展示掛圖，再進(jìn)行簡短介紹，讓學(xué)生了解即可。h.引出減數(shù)分裂的概念，為第五章學(xué)習(xí)打下基礎(chǔ)。小結(jié)：新課講完以后由教師對本節(jié)內(nèi)容進(jìn)行總結(jié)鞏固和反饋：進(jìn)行一些課堂練習(xí)達(dá)到鞏固和反饋的作用。最后布置作業(yè)，各種難度的作業(yè)題目均設(shè)置一些，其中簡單題比重大，難題要求學(xué)生選作，這樣提高學(xué)生學(xué)習(xí)積極性。2教學(xué)媒體程序設(shè)計(jì): 細(xì)胞周期的概念（多媒體課件演示周期動畫）植物細(xì)胞有絲分裂（多媒體課件演示分裂各期動畫）動植物細(xì)胞有絲分裂異同點(diǎn)（多媒體課件演示分裂各期動畫）有絲分裂過程中DNA和染色體數(shù)量的變化規(guī)律（掛圖演示，包括表格和函數(shù)圖象）
人教版高中生物必修1細(xì)胞的能量“通貨”─ATP說課稿
（3）ATP的利用關(guān)于ATP的利用，一是要講清楚吸能反應(yīng)和放能反應(yīng)與ATP的分解和合成的關(guān)系，二是要充分利用教材上的圖解，讓學(xué)生在看懂圖解的基礎(chǔ)上，討論ATP還有哪些用途，從而對該圖解進(jìn)行補(bǔ)充和完善。3、課堂小結(jié)，強(qiáng)化認(rèn)識。ATP作為能量的“通貨”，在生物體生命活動中具有重要的意義。我們不僅要知道ATP的分子結(jié)構(gòu)，還要掌握ATP是如何行使他的貨幣能力。4、板書設(shè)計(jì)結(jié)束：本節(jié)課設(shè)置了一系列問題情境，層層設(shè)問，在學(xué)生答問、質(zhì)疑、討論過程中讓學(xué)生建構(gòu)新概念和新的知識體系，并通過教師及時掌握反饋信息，適時點(diǎn)撥、調(diào)節(jié)，讓學(xué)生在推理判斷中培養(yǎng)良好的思維習(xí)慣和對知識的遷移能力，而且通過留出一定的時間讓學(xué)生提問，體現(xiàn)了以學(xué)生為主體的思想。我的說課完畢，謝謝大家。
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(jī)體造成危害？引導(dǎo)學(xué)生從細(xì)胞代謝需要的物質(zhì)和條件進(jìn)行分析，最后總結(jié)出：內(nèi)環(huán)境穩(wěn)態(tài)是機(jī)體進(jìn)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(jī)體健康？引導(dǎo)學(xué)生從外界環(huán)境和機(jī)體自身調(diào)節(jié)能力兩個方面去思考。即通過加強(qiáng)自我保健，減少外界環(huán)境變化對機(jī)體的不良影響，同時增強(qiáng)機(jī)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(xué)生討論，總結(jié)。1.保護(hù)我們的生存環(huán)境，防治環(huán)境污染。2.加強(qiáng)體育鍛煉，增強(qiáng)體質(zhì)，提高機(jī)體適應(yīng)外界環(huán)境的能力。3.加強(qiáng)自我保健，為機(jī)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(bǔ)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。

3、總結(jié)(這部分要5分鐘)學(xué)生在教師的提示和問題的引導(dǎo)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(diǎn)，起到畫龍點(diǎn)睛的作用，培養(yǎng)了學(xué)生的表達(dá)能力。4、鞏固練習(xí)(這部分要10分鐘)用大屏幕投影把題目投影在屏幕上，讓學(xué)生思考，然后回答。這部分安排10分鐘的時間，讓學(xué)生思考完成具有針對性的練習(xí)，進(jìn)行知識鞏固和教學(xué)效果反饋，及時糾正錯誤的理解和片面的認(rèn)識。5、板書設(shè)計(jì)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(xué)的內(nèi)容，設(shè)計(jì)了如圖所示的板書。在其中，注重了重、難點(diǎn)的突出，使學(xué)生對知識的結(jié)構(gòu)、層次、重點(diǎn)、難點(diǎn)一目了然，便于記憶和理解。四、效果分析對于反射的判斷，學(xué)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(qiáng)調(diào)沒有完整的反射弧結(jié)構(gòu)參與的不是反射。
