    人教版新課標(biāo)高中物理必修2圓周運(yùn)動(dòng)說(shuō)課稿3篇

    設(shè)計(jì)意圖:通過(guò)設(shè)疑、討論及學(xué)生的親身體驗(yàn)與教師的引導(dǎo),得到描述圓周運(yùn)動(dòng)快慢的兩個(gè)物理量,也就成功的打破了學(xué)生在認(rèn)識(shí)上的思維障礙,突破了物理概念教學(xué)的難點(diǎn)。在解決線速度和角速度的問(wèn)題之后,我將引領(lǐng)學(xué)生學(xué)習(xí)勻速圓周運(yùn)動(dòng)的概念以及勻速圓周運(yùn)動(dòng)中線速度、角速度的特點(diǎn)。并引出勻速圓周運(yùn)動(dòng)中周期、轉(zhuǎn)速的知識(shí)。為了加深學(xué)生對(duì)線速度、角速度與半徑關(guān)系的認(rèn)識(shí),我設(shè)計(jì)了第三個(gè)學(xué)生體驗(yàn)活動(dòng):四名學(xué)生以我為圓心做圓周運(yùn)動(dòng),四名學(xué)生始終并列,這時(shí)里圈同學(xué)走動(dòng)不急不慢,而外圈同學(xué)則要小跑。通過(guò)學(xué)生的活動(dòng),不難發(fā)現(xiàn)在角速度相同的情況下,半徑越大的線速度也越大。定性的得到了線速度、角速度與半徑的關(guān)系。接下來(lái)讓學(xué)生利用所學(xué)知識(shí)推導(dǎo)線速度、角速度與半徑的關(guān)系。設(shè)計(jì)意圖:這樣就通過(guò)設(shè)疑、學(xué)生猜想、體驗(yàn)、推導(dǎo)的方式得到了結(jié)論,突破了本節(jié)課的難點(diǎn)即線速度、角速度與半徑的關(guān)系。

    “深入探究,把握主旨”這一步則是解決教學(xué)的重點(diǎn)難點(diǎn),這里涉及到課文的深層意蘊(yùn),學(xué)生理解有難度,教師在通過(guò)問(wèn)題引領(lǐng)學(xué)生探討的基礎(chǔ)上,還要適時(shí)啟發(fā)、點(diǎn)撥,因?yàn)榻虒W(xué)時(shí)間有限,讓學(xué)生漫無(wú)邊際的討論,可能難以完成預(yù)定的教學(xué)任務(wù),會(huì)使教學(xué)過(guò)程不完整。至于本文的寫(xiě)作特點(diǎn)的教學(xué)視時(shí)間而定,有時(shí)間可以讓學(xué)生說(shuō)一說(shuō),沒(méi)有時(shí)間用小黑板出示一下,讓學(xué)生了解就行,如果時(shí)間不夠,甚至可以不講。第三階段是“延伸練習(xí),鞏固提高”。

    四、教學(xué)方法和學(xué)法。課前學(xué)生搜集有關(guān)《詩(shī)經(jīng)》的資料必不可少。另外,時(shí)隔數(shù)千年,年代久遠(yuǎn),文字的障礙很大,然而,過(guò)分糾纏于文字的疏通會(huì)破壞詩(shī)歌的“氣”,喪失詩(shī)歌的“神”,所以在學(xué)習(xí)時(shí),應(yīng)舍去條分縷析的理論評(píng)價(jià),指導(dǎo)學(xué)生結(jié)合注釋疏通文字,然后引領(lǐng)他們經(jīng)由文字再現(xiàn)形象和事件,經(jīng)由形象和事件領(lǐng)略情感,感受其中濃濃的詩(shī)情。誦讀的環(huán)節(jié)是重要的,配以二胡獨(dú)奏《長(zhǎng)相思》,營(yíng)造意境,學(xué)生沉浸在音樂(lè)營(yíng)造的意境中反復(fù)吟詠,讀出節(jié)奏,讀出音調(diào),讀出感情,細(xì)細(xì)體味,讓或優(yōu)或喜的情愫縈繞心間,我們就觸到了先民的靈魂。比興手法為《詩(shī)經(jīng)》獨(dú)創(chuàng),重章疊句同樣別致而新鮮,教學(xué)過(guò)程中結(jié)合具體語(yǔ)境讓學(xué)生自己去發(fā)現(xiàn)并進(jìn)行討論,不搞枯燥的知識(shí)傳授。還引入講故事、改寫(xiě)兩種活潑的學(xué)習(xí)形式,從而達(dá)到加深理解的目的。

    [教學(xué)反思]人教版高中語(yǔ)文必修二第三單元安排了《蘭亭集序》《赤壁賦》《游褒禪山記》三篇古代山水游記散文,它們借游賞之事,探索生命的意義、治學(xué)的道理。師者,所以傳道、授業(yè)、解惑也。高中的教材選用的都是歷史經(jīng)典名篇,每一篇都閃爍著儒道釋等百家光輝的思想。編者要老師傳道的意圖很明顯。即非如此,看著這些影響歷代、影響世界的如日月之耀眼光華的偉大思想就躺在我們的教科書(shū)里,又如何能不講呢?所以,我將本課的教學(xué)重難點(diǎn)擬定為:幫助學(xué)生建立積極的生死觀,掌握多角度看問(wèn)題的正確的思想方法。當(dāng)然,也讓學(xué)生領(lǐng)會(huì)了融寫(xiě)景、抒情、說(shuō)理于一爐的大家手法。整堂課各教學(xué)環(huán)節(jié),環(huán)環(huán)相扣,過(guò)渡自然,讀、思、議、寫(xiě)訓(xùn)練到位,而且全部圍繞“生死觀”展開(kāi),如一篇形散神不散的散文。

    生2:頷聯(lián)的意思是只聽(tīng)到禁衛(wèi)軍中傳來(lái)夜間巡邏的梆子聲,不再向?qū)m中那樣安逸地聽(tīng)到有雞人打鳴報(bào)時(shí)的聲音了。生3:頸聯(lián)的意思是說(shuō)事變發(fā)生那天軍隊(duì)發(fā)生嘩變停留不前,但當(dāng)年唐玄宗以為自己可以和貴妃天天在一起,對(duì)天上的牽牛和織女一年一度的會(huì)見(jiàn)還加以嘲笑呢。生4:尾聯(lián)的含義是為什么唐玄宗當(dāng)了四十五年的皇帝,還不如普通百姓夫妻恩愛(ài),長(zhǎng)相廝守。師:好的。請(qǐng)大家再齊讀一遍詩(shī)文,做到人人都能疏通詩(shī)的含義。學(xué)生再次齊讀。第三環(huán)節(jié):專(zhuān)項(xiàng)探究師:白居易曾說(shuō):“文章合為時(shí)而著,歌詩(shī)合為事而作?!边@首詩(shī)就是作者途經(jīng)馬嵬驛,詠馬嵬之變這一歷史事件而作,所以我們鑒賞的第三步,就是通過(guò)標(biāo)題和詩(shī)文,弄清詩(shī)中的歷史事件。請(qǐng)同學(xué)們找出詩(shī)中哪些詩(shī)句描述了這一事件?

    說(shuō)教材A.教材簡(jiǎn)析《琵琶行(并序)》是人教版《普通高中課程標(biāo)準(zhǔn)實(shí)驗(yàn)教科書(shū)語(yǔ)文》必修3第二單元的一篇講讀課文。本單元學(xué)習(xí)的是唐代詩(shī)歌,共七首詩(shī)?!杜眯校ú⑿颍肥翘拼F(xiàn)實(shí)主義詩(shī)人白居易寫(xiě)的一首歌行體長(zhǎng)篇敘事詩(shī),是我國(guó)古代敘事詩(shī)和音樂(lè)詩(shī)中的“千古絕喝”。詩(shī)歌主題鮮明、人物形象生動(dòng),抒情真切細(xì)膩,具有深刻的思想內(nèi)容和卓越的藝術(shù)技巧。B.教學(xué)目標(biāo)《全日制普通高中高級(jí)中學(xué)語(yǔ)文教學(xué)大綱》明確要求我們:在閱讀教學(xué)過(guò)程中要引導(dǎo)學(xué)生“感受文學(xué)形象,品味文學(xué)作品的語(yǔ)言和藝術(shù)技巧,初步鑒賞文學(xué)作品”。而本單元的教學(xué)要求是培養(yǎng)學(xué)生詩(shī)歌鑒賞的能力。根據(jù)教學(xué)大綱和單元教學(xué)要求,結(jié)合本課特點(diǎn),我制定本課的教學(xué)目標(biāo)是:1.知識(shí)目標(biāo):了解文學(xué)常識(shí);積累重點(diǎn)文言實(shí)詞;品味主旨句“同是天涯淪落人,相逢何必曾相識(shí)”的內(nèi)涵;感知作者把音樂(lè)描寫(xiě)與聽(tīng)者、演奏者的感情融為一體的寫(xiě)作特點(diǎn)。
