《函數(shù)的單調(diào)性與最大（小）值》是高中數(shù)學(xué)新教材第一冊(cè)第三章第2節(jié)的內(nèi)容。在此之前，學(xué)生已學(xué)習(xí)了函數(shù)的概念、定義域、值域及表示法，這為過渡到本節(jié)的學(xué)習(xí)起著鋪墊作用。學(xué)生在初中已經(jīng)學(xué)習(xí)了一次函數(shù)、二次函數(shù)、反比例函數(shù)的圖象，在此基礎(chǔ)上學(xué)生對(duì)增減性有一個(gè)初步的感性認(rèn)識(shí)，所以本節(jié)課是學(xué)生數(shù)學(xué)思想的一次重要提高。函數(shù)單調(diào)性是函數(shù)概念的延續(xù)和拓展，又是后續(xù)研究指數(shù)函數(shù)、對(duì)數(shù)函數(shù)等內(nèi)容的基礎(chǔ)，對(duì)進(jìn)一步研究閉區(qū)間上的連續(xù)函數(shù)最大值和最小值的求法和實(shí)際應(yīng)用，對(duì)解決各種數(shù)學(xué)問題有著廣泛作用。課程目標(biāo)1、理解增函數(shù)、減函數(shù) 的概念及函數(shù)單調(diào)性的定義；2、會(huì)根據(jù)單調(diào)定義證明函數(shù)單調(diào)性；3、理解函數(shù)的最大（小）值及其幾何意義；4、學(xué)會(huì)運(yùn)用函數(shù)圖象理解和研究函數(shù)的性質(zhì).數(shù)學(xué)學(xué)科素養(yǎng)

1.觀察（1）如圖，在陽(yáng)光下觀察直立于地面的旗桿AB及它在地面影子BC,旗桿所在直線與影子所在直線的位置關(guān)系是什么？（2）隨著時(shí)間的變化，影子BC的位置在不斷的變化，旗桿所在直線AB與其影子B’C’所在直線是否保持垂直？經(jīng)觀察我們知道AB與BC永遠(yuǎn)垂直，也就是AB垂直于地面上所有過點(diǎn)B的直線。而不過點(diǎn)B的直線在地面內(nèi)總是能找到過點(diǎn)B的直線與之平行。因此AB與地面上所有直線均垂直。一般地，如果一條直線與一個(gè)平面α內(nèi)所有直線均垂直，我們就說l垂直α，記作l⊥α。2.定義：①文字?jǐn)⑹觯喝绻本€l與平面α內(nèi)的所有 直線都垂直，就說直線l與平面α互相垂直，記作l⊥α.直線l叫做平面α的垂線，平面α叫做直線l的垂面．直線與平面垂直時(shí)，它們唯一的公共點(diǎn)P叫做交點(diǎn)．②圖形語(yǔ)言：如圖．畫直線l與平面α垂直時(shí)，通常把直線畫成與表示平面的平行四邊形的一邊垂直．③符號(hào)語(yǔ)言：任意a?α，都有l(wèi)⊥a?l⊥α.

本課是高中數(shù)學(xué)第一章第4節(jié)，充要條件是中學(xué)數(shù)學(xué)中最重要的數(shù)學(xué)概念之一， 它主要討論了命題的條件與結(jié)論之間的邏輯關(guān)系,目的是為今后的數(shù)學(xué)學(xué)習(xí)特別是數(shù)學(xué)推理的學(xué)習(xí)打下基礎(chǔ)。從學(xué)生學(xué)習(xí)的角度看，與舊教材相比，教學(xué)時(shí)間的前置，造成學(xué)生在學(xué)習(xí)充要條件這一概念時(shí)的知識(shí)儲(chǔ)備不夠豐富，邏輯思維能力的訓(xùn)練不夠充分，這也為教師的教學(xué)帶來一定的困難．“充要條件”這一節(jié)介紹了充分條件,必要條件和充要條件三個(gè)概念,由于這些概念比較抽象,中學(xué)生不易理解,用它們?nèi)ソ鉀Q具體問題則更為困難,因此”充要條件”的教學(xué)成為中學(xué)數(shù)學(xué)的難點(diǎn)之一,而必要條件的定義又是本節(jié)內(nèi)容的難點(diǎn).A.正確理解充分不必要條件、必要不充分條件、充要條件的概念；B.會(huì)判斷命題的充分條件、必要條件、充要條件．C.通過學(xué)習(xí)，使學(xué)生明白對(duì)條件的判定應(yīng)該歸結(jié)為判斷命題的真假.D.在觀察和思考中，在解題和證明題中，培養(yǎng)學(xué)生思維能力的嚴(yán)密性品質(zhì)．

等式性質(zhì)與不等式性質(zhì)是高中數(shù)學(xué)的主要內(nèi)容之一，在高中數(shù)學(xué)中占有重要地位，它是刻畫現(xiàn)實(shí)世界中量與量之間關(guān)系的有效數(shù)學(xué)模型，在現(xiàn)實(shí)生活中有著廣泛的應(yīng)，有著重要的實(shí)際意義.同時(shí)等式性質(zhì)與不等式性質(zhì)也為學(xué)生以后順利學(xué)習(xí)基本不等式起到重要的鋪墊.課程目標(biāo)1. 掌握等式性質(zhì)與不等式性質(zhì)以及推論，能夠運(yùn)用其解決簡(jiǎn)單的問題．2. 進(jìn)一步掌握作差、作商、綜合法等比較法比較實(shí)數(shù)的大小． 3. 通過教學(xué)培養(yǎng)學(xué)生合作交流的意識(shí)和大膽猜測(cè)、樂于探究的良好思維品質(zhì)。數(shù)學(xué)學(xué)科素養(yǎng)1.數(shù)學(xué)抽象：不等式的基本性質(zhì)；2.邏輯推理：不等式的證明；3.數(shù)學(xué)運(yùn)算：比較多項(xiàng)式的大小及重要不等式的應(yīng)用；4.數(shù)據(jù)分析：多項(xiàng)式的取值范圍，許將單項(xiàng)式的范圍之一求出，然后相加或相乘.（將減法轉(zhuǎn)化為加法，將除法轉(zhuǎn)化為乘法）；5.數(shù)學(xué)建模：運(yùn)用類比的思想有等式的基本性質(zhì)猜測(cè)不等式的基本性質(zhì)。
人教A版高中數(shù)學(xué)必修一全稱量詞與存在量詞教學(xué)設(shè)計(jì)（2）
(4)“不論m取何實(shí)數(shù),方程x2+2x-m=0都有實(shí)數(shù)根”是全稱量詞命題,其否定為“存在實(shí)數(shù)m0,使得方程x2+2x-m0=0沒有實(shí)數(shù)根”,它是真命題.解題技巧：（含有一個(gè)量詞的命題的否定方法）(1)一般地,寫含有一個(gè)量詞的命題的否定,首先要明確這個(gè)命題是全稱量詞命題還是存在量詞命題,并找到其量詞的位置及相應(yīng)結(jié)論,然后把命題中的全稱量詞改成存在量詞,存在量詞改成全稱量詞,同時(shí)否定結(jié)論.(2)對(duì)于省略量詞的命題,應(yīng)先挖掘命題中隱含的量詞,改寫成含量詞的完整形式,再依據(jù)規(guī)則來寫出命題的否定.跟蹤訓(xùn)練三3．寫出下列命題的否定,并判斷其真假:(1)p:?x∈R,x2-x+ ≥0;(2)q:所有的正方形都是矩形;(3)r:?x∈R,x2+3x+7≤0;(4)s:至少有一個(gè)實(shí)數(shù)x,使x3+1=0.【答案】見解析【解析】(1) p:?x∈R,x2-x+1/4<0.∵?x∈R,x2-x+1/4=(x"-" 1/2)^2≥0恒成立,∴ p是假命題.

1.探究：根據(jù)基本事實(shí)的推論2,3，過兩條平行直線或兩條相交直線，有且只有一個(gè)平面，由此可以想到，如果一個(gè)平面內(nèi)有兩條相交或平行直線都與另一個(gè)平面平行，是否就能使這兩個(gè)平面平行？如圖（1），a和b分別是矩形硬紙板的兩條對(duì)邊所在直線，它們都和桌面平行，那么硬紙板和桌面平行嗎？如圖（2），c和d分別是三角尺相鄰兩邊所在直線，它們都和桌面平行，那么三角尺與桌面平行嗎？2.如果一個(gè)平面內(nèi)有兩條平行直線與另一個(gè)平面平行，這兩個(gè)平面不一定平行。我們借助長(zhǎng)方體模型來說明。如圖，在平面A’ADD’內(nèi)畫一條與AA’平行的直線EF,顯然AA’與EF都平行于平面DD’CC’,但這兩條平行直線所在平面AA’DD’與平面DD’CC’相交。3.如果一個(gè)平面內(nèi)有兩條相交直線與另一個(gè)平面平行，這兩個(gè)平面是平行的，如圖，平面ABCD內(nèi)兩條相交直線A’C’,B’D’平行。

1.圓柱、圓錐、圓臺(tái)的表面積與多面體的表面積一樣，圓柱、圓錐、圓臺(tái)的表面積也是圍成它的各個(gè)面的面積和。利用圓柱、圓錐、圓臺(tái)的展開圖如圖，可以得到它們的表面積公式：2.思考1：圓柱、圓錐、圓臺(tái)的表面積之間有什么關(guān)系？你能用圓柱、圓錐、圓臺(tái)的結(jié)構(gòu)特征來解釋這種關(guān)系嗎？3.練習(xí)一圓柱的一個(gè)底面積是S，側(cè)面展開圖是一個(gè)正方體，那么這個(gè)圓柱的側(cè)面積是（ ）A 4πS B 2πS C πS D 4.練習(xí)二：如圖所示，在邊長(zhǎng)為4的正三角形ABC中，E，F(xiàn)分別是AB，AC的中點(diǎn)，D為BC的中點(diǎn)，H，G分別是BD，CD的中點(diǎn)，若將正三角形ABC繞AD旋轉(zhuǎn)180°，求陰影部分形成的幾何體的表面積．5. 圓柱、圓錐、圓臺(tái)的體積對(duì)于柱體、錐體、臺(tái)體的體積公式的認(rèn)識(shí)(1)等底、等高的兩個(gè)柱體的體積相同．(2)等底、等高的圓錐和圓柱的體積之間的關(guān)系可以通過實(shí)驗(yàn)得出，等底、等高的圓柱的體積是圓錐的體積的3倍．
