人教版新課標(biāo)高中物理必修2曲線運(yùn)動(dòng)說(shuō)課稿2篇
1、舉例：2、結(jié)論：（1）物體的運(yùn)動(dòng)軌跡是曲線的運(yùn)動(dòng)叫曲線運(yùn)動(dòng)。（2）曲線運(yùn)動(dòng)中速度方向是時(shí)刻改變的。(二)、曲線運(yùn)動(dòng)方向：1、質(zhì)點(diǎn)在某一點(diǎn)（或某一時(shí)刻）的速度的方向是在曲線的這一點(diǎn)的切線方向。2、曲線運(yùn)動(dòng)中速度方向是時(shí)刻改變的，因此曲線運(yùn)動(dòng)是變速運(yùn)動(dòng)。(三)、曲線運(yùn)動(dòng)條件：1、演示實(shí)驗(yàn)：2、結(jié)論：當(dāng)物體所受的合力的方向跟它的速度方向不在同一直線時(shí)，物體就做曲線運(yùn)動(dòng)。七、課堂小結(jié)：1、運(yùn)動(dòng)軌跡是曲線的運(yùn)動(dòng)叫曲線運(yùn)動(dòng)。2、曲線運(yùn)動(dòng)中速度的方向是時(shí)刻改變的，質(zhì)點(diǎn)在某一點(diǎn)的瞬時(shí)速度的方向在曲線的這一點(diǎn)的切線上。3、當(dāng)合外力F的方向與它的速度方向有一夾角a時(shí)，物體做曲線運(yùn)動(dòng)。八、鞏固訓(xùn)練：1、關(guān)于曲線運(yùn)動(dòng)，下列說(shuō)法正確的是（）。A：曲線運(yùn)動(dòng)一定是變速運(yùn)動(dòng)；B：曲線運(yùn)動(dòng)速度的方向不斷的變化，但速度的大小可以不變；
人教版新課標(biāo)小學(xué)數(shù)學(xué)二年級(jí)上冊(cè)2、3、4的乘法口訣 說(shuō)課稿2篇
3、在學(xué)生已有了乘法口訣的數(shù)學(xué)模式后，引導(dǎo)學(xué)生運(yùn)用已有經(jīng)驗(yàn)，親自參與其它乘法口訣的學(xué)習(xí)，充分發(fā)揮學(xué)生的主體作用，發(fā)展學(xué)生的思維。4、多采用提問(wèn)讓學(xué)生思考的方法，讓學(xué)生在操作過(guò)程中想老師提出的問(wèn)題，培養(yǎng)學(xué)生的抽象概括能力。如:在擺了兩根小棒后問(wèn)學(xué)生:現(xiàn)在擺了幾根小棒？可以用幾表示？擺了幾個(gè)2根？用乘法算式應(yīng)怎樣表示等。5、運(yùn)用磁性黑板擺實(shí)物，讓學(xué)生能夠通過(guò)觀察實(shí)物直觀感知，如:問(wèn)2個(gè)2是多少？學(xué)生實(shí)在不能想的可以通過(guò)看圖數(shù)數(shù)來(lái)完成，這樣便可以照顧學(xué)習(xí)有困難的學(xué)生。學(xué)生已經(jīng)對(duì)乘法的含義有了初步的理解，掌握口訣就比較容易；但是，要熟記乘法口訣并準(zhǔn)確的運(yùn)用還需花較大的精力和時(shí)間，因此，要引導(dǎo)學(xué)生學(xué)會(huì)由加法到乘法，再到口訣的歸納法，由易到難，循序漸進(jìn)的方法。如:2個(gè)2，可以用加法22=4，再到寫(xiě)乘法算式2×2=4，再歸納出口訣“二二得四”；先引導(dǎo)學(xué)生說(shuō)出1個(gè)2是多少？編出口訣，再引導(dǎo)說(shuō)出2個(gè)2是多少，編出口訣等等。

（一）、復(fù)習(xí)提問(wèn)1、請(qǐng)說(shuō)出功的計(jì)算公式及功的單位2、我們用哪個(gè)物理量表示物體運(yùn)動(dòng)的快慢？（二）、創(chuàng)設(shè)情景，引入新課1、播放多媒體素材，用起重機(jī)和一個(gè)工人搬運(yùn)幾百塊磚比較哪一種方法好？圖中的情景說(shuō)明了什么問(wèn)題?（教師通過(guò)所設(shè)計(jì)的情景，將學(xué)生引入怎樣比較做功快慢，讓學(xué)生發(fā)表自己的看法，初步知道物體做功是有快慢之分的。）（三）、進(jìn)行新課1、比較做功快慢的方法播放多媒體素材并提出問(wèn)題：怎樣比較兩個(gè)人誰(shuí)做功快誰(shuí)做功慢？教師啟發(fā)：以前學(xué)習(xí)過(guò)要比較兩物體運(yùn)動(dòng)的快慢，可以先確定路程再比較時(shí)間，也可以先確定時(shí)間再比較路程。在路程和時(shí)間都不同時(shí)，通過(guò)計(jì)算速度比較兩物體運(yùn)動(dòng)的快慢。同理，要比較物體做功的快慢可采用什么方法？
人教版新課標(biāo)高中物理必修2功說(shuō)課稿2篇
探究一：高中階段功的含義是什么？投影：初中九年級(jí)《物理》105頁(yè)學(xué)生思考：①圖中物體的勢(shì)能、動(dòng)能分別如何變化？②物體能量的變化和做功是否存在關(guān)系？學(xué)生:分組討論，得出結(jié)論：如果物體的能量發(fā)生變化時(shí)，說(shuō)明有力對(duì)物體做了功。教師:進(jìn)行點(diǎn)評(píng)和小結(jié)(設(shè)計(jì)意圖：對(duì)初中知識(shí)深化理論認(rèn)識(shí)，并為以后功能關(guān)系的教學(xué)作準(zhǔn)備)探究二：力對(duì)物體做功的兩個(gè)要素是什么？情景再現(xiàn)：找體重相對(duì)懸殊的兩位同學(xué)，①A同學(xué)試圖抱起B(yǎng)同學(xué)，但沒(méi)成功。②B同學(xué)抱起A同學(xué)在教室內(nèi)勻速走動(dòng)。學(xué)生思考：在①中，A是否對(duì)B做功？在②中，B是否對(duì)A做功？學(xué)生:分析得出做功的兩要素：物體受到力的作用，并且在力的方向上發(fā)生位移.教師:讓學(xué)生分別例舉生活中力對(duì)物體做功和不做功的例子，（設(shè)計(jì)意圖：讓學(xué)生親身參與課堂實(shí)驗(yàn)，烘托課堂氣氛，相互協(xié)作增進(jìn)同學(xué)情誼）探究三：如果物體的位移不再力的方向上，那么力是否還對(duì)物體做功？
