小學(xué)數(shù)學(xué)人教版五年級(jí)下冊(cè)《容積和容積單位》說課稿
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)。
小學(xué)數(shù)學(xué)人教版五年級(jí)下冊(cè)《長(zhǎng)方體和正方體的認(rèn)識(shí)》說課稿
3.說教學(xué)重、難點(diǎn)依據(jù)數(shù)學(xué)課程標(biāo)準(zhǔn)，及對(duì)教材的認(rèn)識(shí)，我確定了本節(jié)課的重點(diǎn)和難點(diǎn)。教學(xué)重點(diǎn)：掌握長(zhǎng)方體和正方體的特征。教學(xué)難點(diǎn)：建立“立體圖形”的空間概念，了解長(zhǎng)方體、正方體的關(guān)系。二、說教法根據(jù)幾何知識(shí)的教學(xué)特點(diǎn)、本節(jié)教學(xué)內(nèi)容以及小學(xué)生空間觀念薄弱的特點(diǎn)，我將采用以下教學(xué)方法。直觀演示法：利用圖片等手段進(jìn)行直觀演示，激發(fā)學(xué)生的學(xué)習(xí)興趣；觀察發(fā)現(xiàn)法：通過讓學(xué)生觀察長(zhǎng)方體、正方體的一些實(shí)物發(fā)現(xiàn)新知，培養(yǎng)學(xué)生的觀察概括能力；合作探究法：引導(dǎo)學(xué)生通過自主研究、合作討論等活動(dòng)形式來獲取知識(shí)。同時(shí)運(yùn)用多媒體輔助教學(xué)，使學(xué)生的觀察能力、抽象概括能力逐步提高。三、說學(xué)法為了使學(xué)生較好地掌握長(zhǎng)方體和正方體的特征，并逐步形成空間觀念，除了讓學(xué)生通過觀察來認(rèn)識(shí)長(zhǎng)方體和正方體的特征以外，在觀察實(shí)物的基礎(chǔ)上，通過動(dòng)手操作，看一看，摸一摸，數(shù)一數(shù)，量一量，做一做來學(xué)習(xí)新知，同時(shí)以此來激發(fā)學(xué)生的學(xué)習(xí)興趣，調(diào)動(dòng)學(xué)生的積極性。

1. 課前觀看視頻《物理學(xué)與人類文明》2. 分組討論，派代表發(fā)言，談學(xué)習(xí)感受。主要是物理的地位，物理的學(xué)習(xí)方法。3. 高中物理與初中物理在內(nèi)容和方法上的區(qū)別高中物理除了現(xiàn)象、概念和規(guī)律之外還應(yīng)該關(guān)注研究問題的方法，學(xué)會(huì)從先想到抽象，從定性到定量研究問題，學(xué)會(huì)用數(shù)學(xué)方法解決物理問題，學(xué)會(huì)實(shí)驗(yàn)探究，學(xué)會(huì)獨(dú)立分析問題解決問題的思維習(xí)慣。4. 高中物理學(xué)習(xí)的基本要求高中物理學(xué)習(xí)應(yīng)該“重視實(shí)驗(yàn)，勤于思考”和“經(jīng)歷過程，體驗(yàn)方法”。高中物理學(xué)習(xí)與初中物理學(xué)習(xí)雖然有一定區(qū)別，但也不是孤立的，要繼續(xù)堅(jiān)持初中物理學(xué)習(xí)中積累的學(xué)習(xí)方法和體會(huì)，重視從正反兩個(gè)方面加以總結(jié)和提煉，做到：（1） 認(rèn)真閱讀，學(xué)會(huì)自學(xué)要學(xué)好物理，就要認(rèn)真閱讀課本。閱讀課本是要抓住關(guān)鍵詞語，弄清語句間的邏輯順序和因果關(guān)系，領(lǐng)會(huì)文章段落所表達(dá)的物理內(nèi)容，掌握課本敘述物理問題的表達(dá)方法。
