人教版高中生物必修1細胞的衰老與凋亡說課稿
4、最后從生物的壽命引入，探討細胞的死亡。強調(diào)細胞死亡有兩種形式。(1).細胞壞死，它是由某些外界因素造成細胞急速死亡，是一種被動性死亡；(2).細胞凋亡，這是一種由特定基因控制的主動性死亡。細胞壞死與細胞凋亡在形態(tài)學(xué)和生物化學(xué)上有著明顯的區(qū)別。細胞凋亡有廣泛的生物學(xué)意義，比如胚胎發(fā)育期手的發(fā)育如果沒有細胞的調(diào)亡就不會有纖細的手指；如果沒有正常的細胞調(diào)亡，蝌蚪的尾部就不會消失，它將永遠不能變成青蛙……。正常的細胞調(diào)亡還肩負著維持各種組織器官固有體積和形態(tài)的功能；還會使機體內(nèi)異常的細胞得到及時清除，去處潛在的隱患；例如癌癥就是異常的細胞沒有及時死亡的結(jié)果……。因此細胞的正常死亡是生物體的一種非常重要的調(diào)節(jié)機制，是機體平衡細胞增殖，調(diào)節(jié)機體細胞樹木恒定的方式，是必不可少的生命過程。（15分鐘）5、課堂小結(jié)，可以把課堂傳授的知識盡快地轉(zhuǎn)化為學(xué)生的素質(zhì)；簡單扼要的課堂小結(jié)，可使學(xué)生更深刻地理解政治理論在實際生活中的應(yīng)用，并且逐漸地培養(yǎng)學(xué)生具有良好的個性。
人教版高中生物必修1細胞分化說課稿
在講述細胞分化的意義時，也可以用實例來解決，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，而不同細胞的出現(xiàn)就是細胞分化的結(jié)果，所以說，細胞的分化是生物體發(fā)育的基礎(chǔ)。在講到細胞全能性的時候，要多給學(xué)生舉些關(guān)于細胞全能性的例子，如植物組織培養(yǎng)、克隆技術(shù)等等，讓學(xué)生從實際的例子中真正的悟出細胞全能性的含義。此外，還要重視教材中的疑問，適當對題目進行引申,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，從而達到舉一反三的效果。怎樣來解釋細胞的全能性呢？這主要以講授法來解釋了，細胞全能性的體現(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，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。

人教版高中語文必修3《杜甫詩三首》說課稿
我以以《登高》為例，引導(dǎo)學(xué)生進行意象分析，感悟意境美。古人云“立象以盡意”“古詩之妙，專求意象”意象是詩人情感的載體，是詩歌的靈魂。引導(dǎo)學(xué)生張開聯(lián)想和想象的翅膀去感受，去體驗是意象，詩歌鑒賞的關(guān)鍵。科林伍德說“真正藝術(shù)的作品，不是看見的，也不是聽到的，而是想象中的某種東西?！痹娙送ㄟ^想象創(chuàng)造出詩的形象，我們讀者通過想象豐富地再現(xiàn)詩人創(chuàng)造的形象。而感受體驗則是以全部身心投入作品，心靈與心靈相溝通，感情與感情相交流，對詩人的想象活動進行再經(jīng)歷和再體驗。因此，在引導(dǎo)意象解讀中，我先讓學(xué)生點擊這一個，就是通過抓修飾詞、依據(jù)感情基調(diào)、展開想象具體分析本詩中每個意象的情感意蘊和審美意蘊，使學(xué)生明白意象在每首詩中的獨特性。
人教版高中歷史必修3輝煌燦爛的文學(xué)說課稿
教師：不同的時代造就了不同風(fēng)格和不同精神內(nèi)容的詩詞，請同學(xué)們回顧必修一和必修二兩宋中央集權(quán)的加強和經(jīng)濟的發(fā)展狀況。學(xué)生：回憶回答。教師：請同學(xué)們結(jié)合時代背景和詞的特點理解詞為什么能夠成為宋代文學(xué)的主流形式和標志？學(xué)生：兩宋時經(jīng)濟重心轉(zhuǎn)移到了南方，商業(yè)發(fā)展打破了時間和空間的限制，城市繁榮，市民數(shù)量不斷增加。詞的句子長短不齊，便于抒發(fā)感情，并且能夠歌唱，更能適應(yīng)市井生活的需要。于是，詞成為宋代文學(xué)的主流形式和標志。教師：宋代文人地位提高，宋詞就是一個個時代的畫卷：大宋的悲歡離合都寫在了里面。除了詞之外，宋代民間還興起了一種新的詩歌形式，即散曲。學(xué)生：回答散曲的發(fā)展階段及特點、元曲的含義、特點。教師：在中國古代詩歌輝煌發(fā)展的同時，也產(chǎn)生了供人們閑來無事消遣的小說。
