二、問題導(dǎo)學(xué)，主動(dòng)探究，獲取知識(shí)：（給學(xué)生機(jī)會(huì)，參與學(xué)習(xí)過程，有利于對(duì)知識(shí)的感知和對(duì)科學(xué)研究方法的領(lǐng)悟。有利于突破難點(diǎn)。）通過上面的討論及對(duì)初中相關(guān)知識(shí)的回憶可知，核酸是生物體內(nèi)的遺傳物質(zhì)。提問：1 、你知道生物體內(nèi)的核酸有幾種？它們?cè)诩?xì)胞中是如何分布的？ 2 、如何觀察核酸在細(xì)胞中的分布？ 針對(duì)問題，引導(dǎo)學(xué)生閱讀教材及相關(guān)實(shí)驗(yàn)內(nèi)容，組織學(xué)生進(jìn)行實(shí)驗(yàn)。讓學(xué)生閱讀課文及“觀察DNA 和RNA 在細(xì)胞中的分布”實(shí)驗(yàn)，回答問題。實(shí)驗(yàn)后要傾聽、總結(jié)學(xué)生的實(shí)驗(yàn)結(jié)論，繼續(xù)引發(fā)學(xué)生思考：原核細(xì)胞的DNA位于細(xì)胞內(nèi)的什么部位？三、加工、整合信息, 構(gòu)建知識(shí)體系。（充分利用教材中圖示和課件的直觀性特點(diǎn)，發(fā)揮學(xué)生主體作用，引導(dǎo)學(xué)生通過觀察、討論，感知知識(shí)的形成，突出重點(diǎn)）組織學(xué)生閱讀教材并討論： 1、核酸同蛋白質(zhì)一樣，也是生物大分子物質(zhì)，那么，核酸由哪些元素組成？組成它的基本單位是什么？ 2、DNA 和RNA的化學(xué)組成有何異同？ 3、組成核酸的堿基、五碳糖、核苷酸各有幾種？
人教版高中生物必修2基因是有遺傳效應(yīng)的DNA片段說課稿
1.基因的化學(xué)組成：每個(gè)基因含有成百上千個(gè)脫氧核苷酸。講述：基因的脫氧核苷酸排列順序代表遺傳信息。2.基因不同的實(shí)質(zhì)：不同的基因，四種脫氧核苷酸的排列順序不同，但是每個(gè)基因都有特定的排列順序。3.基因的位置：染色體是基因的主要載體，每個(gè)染色體含有一個(gè)DNA分子，每個(gè)DNA分子含有多個(gè)基因，基因在染色體上呈直線排列。4.基因是有遺傳效應(yīng)的DNA片段這就是說，基因是DNA的片段，但必須具有遺傳效應(yīng)（指具有復(fù)制、轉(zhuǎn)錄、翻譯、重組突變及調(diào)控等功能）。有的DNA片段屬間隔區(qū)段，沒有控制性狀的作用，這樣的DNA片段就不是基因?？刂颇撤N性狀的基因有特定的DNA片段，蘊(yùn)含特定的遺傳信息，可以切除，可以拼接到其他生物的DNA上，從而獲得某種性狀的表達(dá)。例如：把牛的胰島素基因拼接到大腸桿菌的DNA上，大腸桿菌可以生產(chǎn)胰島素。

六、說教學(xué)反思由于本節(jié)內(nèi)容抽象復(fù)雜, 插圖多, 涉及的物質(zhì)種類也比較多，應(yīng)要求學(xué)生做好課前預(yù)習(xí)。教學(xué)中，在處理主干知識(shí)和側(cè)枝內(nèi)容的關(guān)系時(shí)，要做到合理分配時(shí)間，明確不同內(nèi)容的教學(xué)要求。教師要注意將知識(shí)及時(shí)進(jìn)行歸納、比較和總結(jié)。要讓學(xué)生了解各個(gè)知識(shí)點(diǎn)間的內(nèi)在關(guān)系，又要能簡(jiǎn)潔、清晰地概述轉(zhuǎn)錄和翻譯的過程。教師在備課時(shí)，一定要仔細(xì)分辨并揣摩插圖所表達(dá)的意思，并能將不同的插圖內(nèi)容與教學(xué)流程有機(jī)地結(jié)合起來。在對(duì)插圖的處理上，還應(yīng)分清主次和輕重。教材在呈現(xiàn)教學(xué)內(nèi)容時(shí)，采用圖文并茂的方式來揭示轉(zhuǎn)錄與翻譯的動(dòng)態(tài)過程。因此，教師不僅要利用插圖達(dá)到形象和直觀的教學(xué)效果，還應(yīng)配合教材中的文字描述作深入淺出的講解，使文字信息與圖形信息結(jié)合起來，讓學(xué)生感知到基因的表達(dá)是一個(gè)多層次的、動(dòng)態(tài)的、相互協(xié)調(diào)和配合的過程。盡可能利用多媒體課件進(jìn)行教學(xué)。多媒體課件可以形象、生動(dòng)地反映基因表達(dá)的過程，這是紙質(zhì)教材難以做到的。
人教版高中生物必修2孟德爾的豌豆雜交實(shí)驗(yàn)說課稿
一、說教材1、教材的地位和作用《孟德爾的豌豆雜交實(shí)驗(yàn)（一）》這一課題是高中生物必修2第一章第一節(jié)第一部分的內(nèi)容，是學(xué)生學(xué)習(xí)孟德爾的豌豆雜交實(shí)驗(yàn)（二）的基礎(chǔ)，也是第二章《減數(shù)分裂與受精作用》這節(jié)知識(shí)的重要基礎(chǔ)，又并為后續(xù)學(xué)習(xí)生物變異與生物進(jìn)化奠基，所以在教材中起到承上啟下的作用。因此從這個(gè)地位來看，這部分內(nèi)容不僅是本章的重點(diǎn)，更是整個(gè)必修2的重點(diǎn)內(nèi)容。本節(jié)的教學(xué)內(nèi)容是按照孟德爾的探索過程由現(xiàn)象到實(shí)質(zhì)，層層深入地展開的。教材首先介紹了孟德爾的雜交實(shí)驗(yàn)方法和觀察到的實(shí)驗(yàn)現(xiàn)象，接著介紹了孟德爾對(duì)實(shí)驗(yàn)現(xiàn)象的分析，然后介紹了對(duì)分離現(xiàn)象解釋的驗(yàn)證，最后歸納總結(jié)出分離定律。在教學(xué)內(nèi)容的組織上體現(xiàn)了學(xué)科內(nèi)在邏輯性與學(xué)生認(rèn)識(shí)規(guī)律的統(tǒng)一。與原教材比較，有了新的突破主要表現(xiàn)在三方面：

人教版高中地理必修2南京的自行車是多了還是少了說課稿
在學(xué)生回答的基礎(chǔ)上進(jìn)行歸納小結(jié)：發(fā)展城市公共交通? 明確道路分工? 合理規(guī)劃停車場(chǎng)? 減少出行距離? 錯(cuò)開出行高峰? 加大城市道路建設(shè)? 進(jìn)行科學(xué)合理的交通管理，重視智能交通系統(tǒng)的建設(shè)提問：這組同學(xué)在幻燈片中提到城市環(huán)境污染源主要有哪些？城市交通環(huán)境問題除了交通工具的尾氣排放帶來大氣污染外，還會(huì)給城市環(huán)境帶來什么問題？這組同學(xué)基本同意自行車多是加劇南京空氣污染的間接原因，你同意他們的觀點(diǎn)嗎？在學(xué)生回答的基礎(chǔ)上，教師進(jìn)行歸納小結(jié)：自行車是一種綠色交通工具，既環(huán)保又經(jīng)濟(jì)。只有當(dāng)它在某些機(jī)動(dòng)車和非機(jī)動(dòng)車不分的地段，影響車輛行駛速度的時(shí)候，它才可能成為加劇空氣污染的間接原因。那么我們針對(duì)交通工具對(duì)環(huán)境造成的影響，除了這組同學(xué)提到的三點(diǎn)解決措施以外，我們還有什么要補(bǔ)充的解決方法嗎？

青蒿素治療瘧疾效果顯著，是抵抗瘧疾耐藥性最好的藥物。中國發(fā)現(xiàn)青蒿素時(shí)，美國也研制出一種抗瘧新藥—化學(xué)合成的甲氟喹，但瘧原蟲很快就適應(yīng)了它，產(chǎn)生耐藥性，臨床使用后患者還出現(xiàn)了明顯的不良反應(yīng)。而對(duì)于青蒿素這種從中草藥中提取的藥物，瘧原蟲對(duì)它完全沒有抵抗能力。1976 年1月，柬埔寨爆發(fā)瘧疾，因瘧原蟲已經(jīng)產(chǎn)生耐藥性，疫情一時(shí)難以控制。中國醫(yī)療隊(duì)攜帶一批青蒿素在柬埔寨大顯神威，挽救了一大批瘧疾患者的生命。

⑦在我看來, 探索太空是值得的。As far as I am concerned, it is worthwhile to explore the space.Step 10 Writing---draftRecently, students in our class have had heated a discussion on whether space is worth exploring. Students hold different ideas about it.30% of us think space exploration is not worthwhile. They think space is too far away from us and our daily life and is a waste of money. And the money spent on space exploration can be used to solve the earth’s problems such as starvation and pollution.On the other hand，70% think space is worth exploring because we have benefited a lot from it，such as using satellites for communication and weather forecast. What’s more，with further space research，we may solve the population problem by moving to other planets one day. Also，space research will enable us to find new sources to solve the problem of energy shortages on the earth.As far as I am concerned, it is worthwhile to explore the space. Not only can it promote the development of society but also enrich our life. Step 11 Pair workExchange drafts with a partner.

Step 3 Analyzing article structureActivity 31. Teachers raise questions to guide students to analyze the chapter structure of this diary and think about how to describe the festival experience. (1)What should be included in the opening/body/closing paragraph(s)?(2)How did the writer arrange his/her ideas?(3)What kind of interesting details did the writer describe?(4)How did the writer describe his/her feelings/emotions during the event?2. Students read and compare the three sentence patterns in activity 2. Try to rewrite the first paragraph of the diary with these three sentence patterns. After that, students exchange corrections with their partners. Such as:●This was my first time spending three days experiencing the Naadam Festival in China’s Inner Mongolia Autonomous Region and it was an enjoyable and exciting experience. ●I'll never forget my experience at the Naadam Festival because it was my first time to watch the exciting Mongolian games of horse racing, wrestling, and archery so closely. ●I'll always remember my first experience at the Naadam Festival in China’s Inner Mongolia Autonomous Region because it was so amazing to spend three days witnessing a grand Mongolian ceremony. Step 4 Accumulation of statementsActivity 41. Ask the students to read the diary again. Look for sentences that express feelings and emotions, especially those with the -ing form and the past participle. Such as:● …h(huán)orse racing, wrestling, and archery, which are all so exciting to watch. ● some amazing performances● I was surprised to see…● I was a little worried about. . . ● feeling really tiredOther emotional statements:●I absolutely enjoyed the archery, too, but the horse races were my favourite part. ●I'm finally back home now, feeling really tired, but celebrating Naadam with my friend was totally worth it. ●He invited me back for the winter to stay in a traditional Mongolian tent and cat hot pot. I can’t wait!2. In addition to the use of the -ing form and the past participle, the teacher should guide the students in the appreciation of these statements, ask them to memorize them, and encourage them to use them reasonably in writing practice.
