3、遺傳密碼的特點(diǎn) 連續(xù)性、簡(jiǎn)并性、通用性5、課堂練習(xí)6、作業(yè)布置假如，我們利用(ACU)n核苷酸長(zhǎng)鏈合成了含有蘇氨酸的多肽，那么蘇氨酸可能的密碼子有哪些？如何運(yùn)用實(shí)驗(yàn)方法確證蘇氨酸的密碼子究竟是什么？七、教學(xué)反思1、教材中豐富的科學(xué)史料，是我們?cè)谡n堂上進(jìn)行探究性學(xué)習(xí)活動(dòng)的良好素材，教師要整理和運(yùn)用好。千萬(wàn)不要低估學(xué)生的思維能力，當(dāng)學(xué)生的思維能力被你想方設(shè)法激發(fā)出來(lái)的時(shí)候，你會(huì)發(fā)現(xiàn)他們的創(chuàng)造力是無(wú)窮的。2、探究性學(xué)習(xí)的目的并不僅僅是問(wèn)題的解決，更重要的是在探究過(guò)程中體驗(yàn)和獲取科學(xué)研究方法，培養(yǎng)合作與分享的精神以及實(shí)事求是的科學(xué)態(tài)度，鍛煉思維能力，提高科學(xué)素養(yǎng)。3、學(xué)生是學(xué)習(xí)的主體，教師是引導(dǎo)者。我們要采取措施讓學(xué)生積極主動(dòng)地參與到學(xué)習(xí)活動(dòng)中來(lái)，通過(guò)他們的思考、討論、爭(zhēng)辯、合作等活動(dòng)來(lái)獲取方法，建構(gòu)知識(shí)。
人教版高中歷史必修3輝煌燦爛的文學(xué)說(shuō)課稿
教師：不同的時(shí)代造就了不同風(fēng)格和不同精神內(nèi)容的詩(shī)詞，請(qǐng)同學(xué)們回顧必修一和必修二兩宋中央集權(quán)的加強(qiáng)和經(jīng)濟(jì)的發(fā)展?fàn)顩r。學(xué)生：回憶回答。教師：請(qǐng)同學(xué)們結(jié)合時(shí)代背景和詞的特點(diǎn)理解詞為什么能夠成為宋代文學(xué)的主流形式和標(biāo)志？學(xué)生：兩宋時(shí)經(jīng)濟(jì)重心轉(zhuǎn)移到了南方，商業(yè)發(fā)展打破了時(shí)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(zhǎng)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(biāo)志。教師：宋代文人地位提高，宋詞就是一個(gè)個(gè)時(shí)代的畫(huà)卷：大宋的悲歡離合都寫(xiě)在了里面。除了詞之外，宋代民間還興起了一種新的詩(shī)歌形式，即散曲。學(xué)生：回答散曲的發(fā)展階段及特點(diǎn)、元曲的含義、特點(diǎn)。教師：在中國(guó)古代詩(shī)歌輝煌發(fā)展的同時(shí)，也產(chǎn)生了供人們閑來(lái)無(wú)事消遣的小說(shuō)。
