    一般情況下,凡是支持物對(duì)物體的支持力,都是支持物因發(fā)生形變而對(duì)物體產(chǎn)生彈力。所以支持力的方向總是垂直于支持面而指向被支持的物體。例1:放在水平桌面上的書書由于重力的作用而壓迫桌面,使書和桌面同時(shí)發(fā)生微小形變,要恢復(fù)原狀,對(duì)桌面產(chǎn)生垂直于桌面向下的彈力f1,這就是書對(duì)桌面的壓力;桌面由于發(fā)生微小的形變,對(duì)書產(chǎn)生垂直于書面向上的彈力f2,這就是桌面對(duì)書的支持力。學(xué)生分析:靜止地放在傾斜木板上的書,書對(duì)木板的壓力和木板對(duì)書的支持力。并畫出力的示意圖。結(jié)論:壓力、支持力都是彈力。壓力的方向總是垂直于支持面而指向被壓的物體,支持力的方向總是垂直于支持面而指向被支持的物體。引導(dǎo)學(xué)生分析靜止時(shí),懸繩對(duì)重物的拉力及方向。引導(dǎo)得出:懸掛物由于重力的作用而拉緊懸繩,使重物、懸繩同時(shí)發(fā)生微小的形變。重物由于發(fā)生微小的形變,對(duì)懸繩產(chǎn)生豎直向下的彈力f1,這是物對(duì)繩的拉力;懸繩由于發(fā)生微小形變,對(duì)物產(chǎn)生豎直向上的彈力f2,這就是繩對(duì)物體的拉力。

    1.用CAI課件模擬汽車的啟動(dòng)過程。師生共同討論:①如果作用在物體上的力為恒力,且物體以勻速運(yùn)動(dòng),則力對(duì)物體做功的功率保持不變。此情況下,任意一段時(shí)間內(nèi)的平均功率與任一瞬時(shí)的瞬時(shí)功率都是相同的。②很多動(dòng)力機(jī)器通常有一個(gè)額定功率,且通常使其在額定功率狀態(tài)工作(如汽車),根據(jù)P=FV可知:當(dāng)路面阻力較小時(shí),牽引力也小,速度大,即汽車可以跑得快些;當(dāng)路面阻力較大,或爬坡時(shí),需要比較大的牽引力,速度必須小。這就是爬坡時(shí)汽車換低速擋的道理。③如果動(dòng)力機(jī)器在實(shí)際功率小于額定功率的條件下工作,例如汽車剛剛起動(dòng)后的一段時(shí)間內(nèi),速度逐漸增大過程中,牽引力仍可增大,即F和v可以同時(shí)增大,但是這一情況應(yīng)以二者乘積等于額定功率為限度,即當(dāng)實(shí)際功率大于額定功率以后,這種情況不可能實(shí)現(xiàn)。

    一、說教材:1.說課內(nèi)容:本節(jié)課的內(nèi)容是北師大版5年級(jí)數(shù)學(xué)下冊(cè)第8單元的《復(fù)式折線統(tǒng)計(jì)圖》。2.教材分析:這節(jié)課的內(nèi)容是在學(xué)生學(xué)習(xí)了單式折線統(tǒng)計(jì)圖和復(fù)式條形統(tǒng)計(jì)圖的基礎(chǔ)上教學(xué)的。這節(jié)課的內(nèi)容包括制作復(fù)式折線統(tǒng)計(jì)圖的必要性、制作方法以及對(duì)這種統(tǒng)計(jì)圖的分析預(yù)測(cè)。教材在設(shè)計(jì)中,主要突出了以下兩個(gè)方面:(1)對(duì)比。為了方便比較甲、乙兩個(gè)城市各月的降水量,把兩個(gè)單式折線統(tǒng)計(jì)圖畫在同一幅圖上,變成復(fù)式折線統(tǒng)計(jì)圖。讓學(xué)生感受出現(xiàn)復(fù)式折線統(tǒng)計(jì)圖的必要性和其帶來的好處。(2)讀圖。通過對(duì)復(fù)式折線統(tǒng)計(jì)圖中兩條折線升降的分析,對(duì)數(shù)據(jù)進(jìn)行合理的預(yù)測(cè),這也是課標(biāo)的要求。3.教材的地位和作用:本課的學(xué)習(xí),不但可以用來解決日常生活中的一些實(shí)際問題,也是今后學(xué)習(xí)更多其他統(tǒng)計(jì)圖的重要基礎(chǔ)。

    4、幸運(yùn)碰撞文文選了一條近的路,然后順利的來到了猴山。但是猴山的門被設(shè)置了密碼,密碼是由兩位數(shù)組成,十位上是2、4、9這三個(gè)數(shù)中的任意一個(gè),個(gè)位上是3、6、8三個(gè)數(shù)中的任意一個(gè),文文最少幾次,最多幾次可以打開門呢?組織學(xué)生小組合作利用卡片拉一拉,并記錄結(jié)果,全班交流。根據(jù)學(xué)生匯報(bào),板書組合結(jié)果。5、拍照留念看到小朋友們玩得這么開心,聰聰和明明也來了。他們還帶來了照相機(jī),在這美好的時(shí)刻,新的問題又隨之而來:四個(gè)小朋友每人都要和聰聰、明明單獨(dú)各合一張影,一共要照多少張照片呢?孩子們可以在小組內(nèi)扮演角色,記錄不同的方法,還讓學(xué)生當(dāng)小攝影師,其余同學(xué)來評(píng)價(jià)。(三)匯報(bào)收獲,拓展內(nèi)化。請(qǐng)同學(xué)們回顧一下這節(jié)課都解決了哪些問題?怎樣解決的?學(xué)生匯報(bào)完后,強(qiáng)調(diào):在搭配中要做到既不重復(fù)又不遺漏就必須按一定的順序進(jìn)行觀察、操作。在今后的學(xué)習(xí)生活中還會(huì)遇到許多這樣的問題,鼓勵(lì)學(xué)生只要發(fā)揮自己的聰明才智就一定能解決出來。

    因此,我從學(xué)生已有的生活出發(fā),尋找例子,幫助學(xué)生理解容積的概念。同時(shí)也多次提供了實(shí)踐機(jī)會(huì),讓學(xué)生自己操作實(shí)驗(yàn)的過程,在操作中感知1升、1毫升的大小和容積單位和體積單位之間的關(guān)系。二、說教學(xué)目標(biāo)1、理解容積的概念,認(rèn)識(shí)常用的容積單位,感知1升和1毫升的實(shí)際大小,并掌握容積單位、體積單位間的進(jìn)率。2、通過實(shí)驗(yàn)的方法,使學(xué)生經(jīng)歷探究容積單位、容積單位和體積單位之間的關(guān)系的過程。三、教學(xué)重難點(diǎn):1、建立容積和容積單位概念,知道容積單位和體積單位的關(guān)系。2、會(huì)計(jì)算容積。四、說教法為了使課堂的主人能活躍起來,我用了自主探究式發(fā)現(xiàn)問題、談?wù)摻涣骱蛯?shí)驗(yàn)教學(xué)的方法進(jìn)行教學(xué),從而也激發(fā)了學(xué)生的積極性和主動(dòng)性。五、說學(xué)法:更多的是引導(dǎo)學(xué)生在自主嘗試、觀察、討論和探究中獲取知識(shí)。

    一、說教材 在學(xué)習(xí)本課前,學(xué)生對(duì)筆算整數(shù)加減法已經(jīng)熟練掌握,并且以元、角、分等常用計(jì)量單位的知識(shí)作為學(xué)習(xí)小數(shù)的形象支撐,已經(jīng)初步認(rèn)識(shí)了小數(shù),也為學(xué)習(xí)本課做了有力的鋪墊。加、減法結(jié)合元角進(jìn)行教學(xué),以便于學(xué)生聯(lián)系實(shí)際來初步學(xué)習(xí)小數(shù)的加減。本節(jié)課內(nèi)容是為以后系統(tǒng)學(xué)習(xí)小數(shù)打下基礎(chǔ)。小數(shù)在生活中應(yīng)用廣泛,是生活的濃縮和提煉,具有現(xiàn)實(shí)的意義,可以迅速達(dá)到學(xué)以致用的目的,有利于學(xué)生體會(huì)處處有數(shù)學(xué),融生活課堂于一體。數(shù)學(xué)的價(jià)值得到淋漓盡致的體現(xiàn)。根據(jù)本課所處的地位和作用以及學(xué)生的年齡特點(diǎn),我制定了以下教學(xué)目標(biāo)。
