    人教版高中生物必修2孟德?tīng)柕耐愣闺s交實(shí)驗(yàn)說(shuō)課稿

    一、說(shuō)教材1、教材的地位和作用《孟德?tīng)柕耐愣闺s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?tīng)柕耐愣闺s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(lái)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?tīng)柕奶剿鬟^(guò)程由現(xiàn)象到實(shí)質(zhì),層層深入地展開(kāi)的。教材首先介紹了孟德?tīng)柕碾s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?tīng)枌?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3地理環(huán)境對(duì)區(qū)域發(fā)展的影響說(shuō)課稿

    本節(jié)課我分成兩個(gè)課時(shí)A首先我會(huì)在在ppt上放幾張關(guān)于區(qū)域的圖,讓學(xué)生思考什么是區(qū)域,區(qū)域有什么特征。其次我會(huì)在在書(shū)上畫(huà)出區(qū)域的定義,在給與解釋說(shuō)明,再在書(shū)上畫(huà)出區(qū)域的四個(gè)特征,讓同學(xué)小組討論哪些區(qū)域是有界的,哪些區(qū)域是無(wú)界的,從而加深同學(xué)們對(duì)區(qū)域的理解。B在ppt上放出長(zhǎng)江三角洲和松嫩平原,不同風(fēng)土人情由此導(dǎo)入下一個(gè)知識(shí)點(diǎn):不同區(qū)域由于地理環(huán)境的差異,人們的生產(chǎn)特點(diǎn)有許多的不同,發(fā)展方式也存在差異,然后讓學(xué)生思考長(zhǎng)江三角洲和松嫩平原有什么差異,各自給區(qū)域環(huán)境發(fā)展帶來(lái)什么影響,啟發(fā)學(xué)生從氣候等方向思考,然后用表格的方式給不同因素歸類(lèi)(歸位自然和社會(huì)經(jīng)濟(jì)兩大類(lèi))再啟發(fā)同學(xué)們從兩大類(lèi)分別討論對(duì)農(nóng)業(yè)與工業(yè)發(fā)展的影響,最后再用表格的形式分類(lèi)表達(dá)C然后給同學(xué)們幾個(gè)問(wèn)題,鞏固同學(xué)課堂所學(xué),最后留下一個(gè)問(wèn)題課后解決:除了今天講的因素外還有哪些因素對(duì)區(qū)域發(fā)展產(chǎn)生影響?

    第三階段:分班交流論證,歸納整理成文在學(xué)生分組搜集整理資料的基礎(chǔ)之上,我們又以班級(jí)為單位由核心組成員組織資料交流并展開(kāi)討論,共同歸納整理,集體完成《常熟建設(shè)現(xiàn)代農(nóng)業(yè)科技園區(qū)可行性分析調(diào)查表》中的相關(guān)內(nèi)容,交給各自的指導(dǎo)老師修改。第四階段:分片走進(jìn)園區(qū),體驗(yàn)總結(jié)反思我們本著“熟悉家鄉(xiāng)、就近考察”的原則把全年級(jí)的學(xué)生分成八組,分別到八個(gè)園區(qū)開(kāi)展實(shí)地調(diào)查。組織他們聽(tīng)園區(qū)領(lǐng)導(dǎo)或?qū)I(yè)人員介紹園區(qū)的建設(shè)情況和遠(yuǎn)景規(guī)劃,深入田間地頭和溫室大棚參觀園區(qū)生產(chǎn)裝備和農(nóng)民勞動(dòng)場(chǎng)景,開(kāi)展園區(qū)勞動(dòng)體驗(yàn),與園區(qū)農(nóng)民交談等系列活動(dòng)。要求大家在體驗(yàn)勞動(dòng)、收獲快樂(lè)的同時(shí),對(duì)照《常熟現(xiàn)代化農(nóng)業(yè)園區(qū)建設(shè)和發(fā)展情況調(diào)查表》的內(nèi)容逐一展開(kāi)討論并認(rèn)真填寫(xiě)。在此基礎(chǔ)上,我們又要求各片的同學(xué)認(rèn)真反思每個(gè)園區(qū)在發(fā)展過(guò)程中還有哪些不夠完美的地方和需要改進(jìn)的建議。

    人教版高中歷史必修3“罷黜百家獨(dú)尊儒術(shù)”說(shuō)課稿2篇

    1、漢武帝尊儒的措施:(1)政治方面:起用很多儒學(xué)家參與國(guó)家大政。他規(guī)定,地方定期選出孝子、廉吏當(dāng)中央任官,甚至還擢升平民、儒士為相。這明顯擴(kuò)大了官員的隊(duì)伍,提高了官員的文化素質(zhì),鞏固了封建統(tǒng)治基礎(chǔ),成為漢武帝文治武功的重要組成部分。也給后世封建王朝在用人方式方法上面提供了寶貴的借鑒和啟迪。(2)思想方面:采納董仲舒的建議,“罷黜百家 獨(dú)尊儒術(shù)”(3)教育方面:儒家經(jīng)典“五經(jīng)”為國(guó)家規(guī)定的教科書(shū)。興辦太學(xué)和設(shè)立地方學(xué)校進(jìn)行儒學(xué)教育。公元前136年,漢武帝正式規(guī)定《詩(shī)》、《書(shū)》、《禮》、《易》、《春秋》為“五經(jīng)”;前124年,又在長(zhǎng)安興辦太學(xué),規(guī)定太學(xué)生員為博士弟子,一律由儒家五經(jīng)博士負(fù)責(zé)教授,學(xué)完經(jīng)考試合格后即可到政府任官。這是封建國(guó)家利用政權(quán)的力量興辦教育、提倡儒學(xué),其必然對(duì)整個(gè)社會(huì)的教育事業(yè)有一定的導(dǎo)向作用。

    當(dāng)代社會(huì)生活的變化比以往任何時(shí)代都要快。語(yǔ)言尤其是詞匯記錄了這些發(fā)展變化,因而也涌現(xiàn)了大量的新詞新語(yǔ)。據(jù)統(tǒng)計(jì),近幾年每年大約要出現(xiàn)1000個(gè)左右的新詞新語(yǔ),而字典、詞典的多次修訂、增補(bǔ)就反映了這種情況。但相對(duì)來(lái)說(shuō),也有一些流行語(yǔ)又逐漸受到冷遇,甚至退隱。為了更好的對(duì)新詞新語(yǔ)與流行文化作一番檢視與探究,那讓我們考察一下它們是怎么產(chǎn)生的吧?老師先給同學(xué)們列舉四種途徑:大屏幕3。同學(xué)們能再舉出以上途徑的一些例子嗎?老師列舉(4)其實(shí)不只這些,那還有哪些途徑呢?找同學(xué)說(shuō)并舉例。說(shuō)的非常好,請(qǐng)同學(xué)們看老師的例子,總結(jié)(5)。從新詞新語(yǔ)的產(chǎn)生途徑可以看出,這些鮮活得像畫(huà)一樣的新詞就是這個(gè)時(shí)代跳動(dòng)的血小板,它涉及當(dāng)代社會(huì)的重大事件、現(xiàn)象與時(shí)弊,以及人們?nèi)粘I畹母鱾€(gè)層面如人生意義、生活方式、愛(ài)情、友情、就業(yè)、消費(fèi)、時(shí)尚等,時(shí)代性強(qiáng),傳播面廣,反映著當(dāng)代社會(huì)時(shí)局與人們文化心態(tài)的變化。

    新人教版高中英語(yǔ)必修3Unit 4 Space Exploration-Listening&Speaking&Talking教學(xué)設(shè)計(jì)二

    The themes of this part are “Talk about how to become an astronaut” and “Talk about life in space”. As Neil Armstrong said “Mystery creates wonder and wonder is the basis of man’s desire to understand. Space is difficult for human to reach, therefore, humans are full of wonders about it. However, if wanting to achieve the dream of reaching the Moon, some of our human should work hard to be an astronaut at first. Part A(Talk about how to become an astronaut) is a radio interview in a radio studio, where the host asked the Chinese astronauts about his story how to become an astronaut. Yang Liwei told his dreamed to be an astronaut since childhood. Then he worked hard to get into college at 22. The next 10 years, he gradually became an experienced pilot. At the same time, to be an astronaut, he had to study hard English, science and astronomy and trained hard to keep in good physical and mental health and to practise using space equipment. Part B (Talk about life in space) is also an interview with the astronaut Brown, who is back on the earth. The host Max asked about his space life, such as his emotion about going back the earth, the eating, shower, brushing, hobbies and his work. Part A and Part B are interviews. So expressing curiosity about the guests’ past life is a communicative skill, which students should be guided to learn.1. Students can get detailed information about how Yang Liwei became an astronaut and Max’s space life.2. Students learn to proper listening strategy to get detailed information---listening for numbers and taking notes.3. Students can learn related sentences or phrases to express their curiosity like “ I wish to know...” “I’d love to know...”4. Students can learn more about the space and astronauts, even be interested in working hard to be an astronaut

    ⑦在我看來(lái), 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. Use this checklist to help your partner revise his/her draft.1.Does the writer explain why he/she changed/wanted to change?2.Does the writer tell how the changes have improved or will improve his/her life?3.Is the text well-organised?4.Does the writer use words and expressions to show similarities and differences?5.Are there any grammar or spelling errors?6.Does the writer use correct punctuation?
