    人教版新課標(biāo)高中物理必修1摩擦力說(shuō)課稿2篇

    本節(jié)課是人教社物理必修1第三章第三節(jié)的內(nèi)容,編排在彈力之后。該節(jié)知識(shí)既是力學(xué)的基礎(chǔ),也是組成整個(gè)高中物理知識(shí)的一塊“基石”,所以這節(jié)內(nèi)容的教學(xué)如何引領(lǐng)學(xué)生自主積極地探究摩擦力產(chǎn)生的條件和影響因素,體驗(yàn)?zāi)Σ亮μ攸c(diǎn)規(guī)律的發(fā)生過(guò)程是本節(jié)課的重點(diǎn),應(yīng)高度重視本節(jié)教學(xué)過(guò)程;由于摩擦力問(wèn)題的復(fù)雜性,且在具體問(wèn)題中又表現(xiàn)出“動(dòng)中有靜,靜中有動(dòng)”,尤其靜摩擦在許多情形下似乎又是“若有若無(wú),方向不定”,因此,對(duì)于初學(xué)者也是有一定難度的。也正是由于教材內(nèi)容的上述特點(diǎn),本節(jié)課又易于激起學(xué)生的求知欲,易于培養(yǎng)學(xué)生的辯證觀點(diǎn),易于錘煉學(xué)生的物理素質(zhì)。要充分用好該節(jié)教材內(nèi)容,深入挖掘知識(shí)間的有機(jī)聯(lián)系,對(duì)學(xué)生開(kāi)展針對(duì)性的思維訓(xùn)練,進(jìn)而提高學(xué)生應(yīng)用物理知識(shí)解決實(shí)際問(wèn)題的能力和創(chuàng)新思維能力。高中物理《課標(biāo)》對(duì)該知識(shí)點(diǎn)的要求是,“通過(guò)實(shí)驗(yàn)認(rèn)識(shí)滑動(dòng)摩擦、靜摩擦的規(guī)律,能用動(dòng)摩擦因數(shù)計(jì)算摩擦力”。其中,對(duì)靜摩擦力規(guī)律的認(rèn)識(shí)應(yīng)該包括最大靜摩擦力。

    一、說(shuō)教材本節(jié)課選自于人教版語(yǔ)文必修二第二單元詩(shī)三首中的一首詩(shī)歌,它是陶淵明歸隱后的作品。寫(xiě)的是田園之樂(lè),實(shí)際表明的是作者不愿與世俗同流合污的心聲,甘愿守著自己的拙志回歸田園。學(xué)習(xí)該詩(shī),有助于學(xué)生了解山水田園詩(shī)的特點(diǎn),感受者作者不同流俗的高尚情操,同時(shí)可以培養(yǎng)學(xué)生初步的鑒賞古典詩(shī)歌的能力。

    “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。

    (二)分析課文,理清思路第1、2段為第一部分,主要是敘事、寫(xiě)景,先敘述集會(huì)的時(shí)間、地點(diǎn),然后渲染出蘭亭優(yōu)美的自然環(huán)境。在這里足以“游目騁懷”“極視聽(tīng)之娛”,可以自由地觀察、思考,滿(mǎn)足人們目視耳聞的需求。這里正是與會(huì)“暢敘幽情”、盡興盡歡的絕好處所。這些描寫(xiě)都富有詩(shī)情畫(huà)意,作者的情感是輕松愉快的。第3、4段為第二部分,主要是抒情、議論,作者由美景妙時(shí)引發(fā)出樂(lè)與憂(yōu)、生與死的感慨。他認(rèn)為人生的快樂(lè)是有極限的,待快樂(lè)得到滿(mǎn)足時(shí),就會(huì)感覺(jué)興味索然。往事轉(zhuǎn)眼間便成為歷史,人到了生命的盡頭就會(huì)死亡。作者由“一死生為虛誕,齊彭殤為妄作”的認(rèn)識(shí),產(chǎn)生了一種珍惜時(shí)間、眷戀生活、熱愛(ài)文明的思考。雖然文中的壽夭、生死不能自由決定,從而有些傷感,但作者仍然認(rèn)識(shí)到盛衰、生死是必然的。人生無(wú)常,時(shí)不我待,故著文留傳后世,以承襲前人,啟示來(lái)者。
