直線的兩點(diǎn)式方程教學(xué)設(shè)計(jì)人教A版高中數(shù)學(xué)選擇性必修第一冊(cè)
解析：①過(guò)原點(diǎn)時(shí)，直線方程為y＝－34x.②直線不過(guò)原點(diǎn)時(shí)，可設(shè)其方程為xa＋ya＝1，∴4a＋－3a＝1，∴a＝1.∴直線方程為x＋y－1＝0.所以這樣的直線有2條，選B.答案：B4.若點(diǎn)P(3,m)在過(guò)點(diǎn)A(2,-1),B(-3,4)的直線上,則m= . 解析:由兩點(diǎn)式方程得,過(guò)A,B兩點(diǎn)的直線方程為(y"-(-" 1")" )/(4"-(-" 1")" )=(x"-" 2)/("-" 3"-" 2),即x+y-1=0.又點(diǎn)P(3,m)在直線AB上,所以3+m-1=0,得m=-2.答案:-2 5.直線ax+by=1(ab≠0)與兩坐標(biāo)軸圍成的三角形的面積是 . 解析:直線在兩坐標(biāo)軸上的截距分別為1/a 與 1/b,所以直線與坐標(biāo)軸圍成的三角形面積為1/(2"|" ab"|" ).答案:1/(2"|" ab"|" )6.已知三角形的三個(gè)頂點(diǎn)A(0,4)，B(－2,6)，C(－8,0)．(1)求三角形三邊所在直線的方程；(2)求AC邊上的垂直平分線的方程．解析(1)直線AB的方程為y－46－4＝x－0－2－0，整理得x＋y－4＝0；直線BC的方程為y－06－0＝x＋8－2＋8，整理得x－y＋8＝0；由截距式可知，直線AC的方程為x－8＋y4＝1，整理得x－2y＋8＝0.(2)線段AC的中點(diǎn)為D(－4,2)，直線AC的斜率為12，則AC邊上的垂直平分線的斜率為－2，所以AC邊的垂直平分線的方程為y－2＝－2(x＋4)，整理得2x＋y＋6＝0.
空間向量基本定理教學(xué)設(shè)計(jì)人教A版高中數(shù)學(xué)選擇性必修第一冊(cè)
反思感悟用基底表示空間向量的解題策略1.空間中,任一向量都可以用一個(gè)基底表示,且只要基底確定,則表示形式是唯一的.2.用基底表示空間向量時(shí),一般要結(jié)合圖形,運(yùn)用向量加法、減法的平行四邊形法則、三角形法則,以及數(shù)乘向量的運(yùn)算法則,逐步向基向量過(guò)渡,直至全部用基向量表示.3.在空間幾何體中選擇基底時(shí),通常選取公共起點(diǎn)最集中的向量或關(guān)系最明確的向量作為基底,例如,在正方體、長(zhǎng)方體、平行六面體、四面體中,一般選用從同一頂點(diǎn)出發(fā)的三條棱所對(duì)應(yīng)的向量作為基底.例2.在棱長(zhǎng)為2的正方體ABCD-A1B1C1D1中,E,F分別是DD1,BD的中點(diǎn),點(diǎn)G在棱CD上,且CG=1/3 CD(1)證明:EF⊥B1C;(2)求EF與C1G所成角的余弦值.思路分析選擇一個(gè)空間基底,將(EF) ?,(B_1 C) ?,(C_1 G) ?用基向量表示.(1)證明(EF) ?·(B_1 C) ?=0即可;(2)求(EF) ?與(C_1 G) ?夾角的余弦值即可.(1)證明:設(shè)(DA) ?=i,(DC) ?=j,(DD_1 ) ?=k,則{i,j,k}構(gòu)成空間的一個(gè)正交基底.

一、情境導(dǎo)學(xué)前面我們已經(jīng)得到了兩點(diǎn)間的距離公式，點(diǎn)到直線的距離公式，關(guān)于平面上的距離問(wèn)題，兩條直線間的距離也是值得研究的。思考1：立定跳遠(yuǎn)測(cè)量的什么距離？A.兩平行線的距離 B.點(diǎn)到直線的距離 C. 點(diǎn)到點(diǎn)的距離二、探究新知思考2：已知兩條平行直線l_1,l_2的方程，如何求l_1 〖與l〗_2間的距離？根據(jù)兩條平行直線間距離的含義，在直線l_1上取任一點(diǎn)P（x_0,y_0 ），,點(diǎn)P（x_0,y_0 ）到直線l_2的距離就是直線l_1與直線l_2間的距離，這樣求兩條平行線間的距離就轉(zhuǎn)化為求點(diǎn)到直線的距離。兩條平行直線間的距離1. 定義：夾在兩平行線間的__________的長(zhǎng).公垂線段2. 圖示： 3. 求法：轉(zhuǎn)化為點(diǎn)到直線的距離.1．原點(diǎn)到直線x＋2y－5＝0的距離是( )A．2 B．3 C．2 D．5D [d＝|－5|12＋22＝5.選D.]
圓的一般方程教學(xué)設(shè)計(jì)人教A版高中數(shù)學(xué)選擇性必修第一冊(cè)
情境導(dǎo)學(xué)前面我們已討論了圓的標(biāo)準(zhǔn)方程為(x-a)2+(y-b)2=r2,現(xiàn)將其展開(kāi)可得：x2+y2-2ax-2bx+a2+b2-r2=0.可見(jiàn),任何一個(gè)圓的方程都可以變形x2+y2+Dx+Ey+F=0的形式.請(qǐng)大家思考一下,形如x2+y2+Dx+Ey+F=0的方程表示的曲線是不是圓?下面我們來(lái)探討這一方面的問(wèn)題.探究新知例如,對(duì)于方程x^2+y^2-2x-4y+6=0,對(duì)其進(jìn)行配方，得〖(x-1)〗^2+(〖y-2)〗^2=-1,因?yàn)槿我庖稽c(diǎn)的坐標(biāo) (x,y) 都不滿(mǎn)足這個(gè)方程，所以這個(gè)方程不表示任何圖形，所以形如x2+y2+Dx+Ey+F=0的方程不一定能通過(guò)恒等變換為圓的標(biāo)準(zhǔn)方程，這表明形如x2+y2+Dx+Ey+F=0的方程不一定是圓的方程.一、圓的一般方程（1）當(dāng)D2+E2-4F>0時(shí),方程x2+y2+Dx+Ey+F=0表示以(-D/2,-E/2)為圓心,1/2 √(D^2+E^2 "-" 4F)為半徑的圓,將方程x2+y2+Dx+Ey+F=0，配方可得〖(x+D/2)〗^2+(〖y+E/2)〗^2=(D^2+E^2-4F)/4（2）當(dāng)D2+E2-4F=0時(shí),方程x2+y2+Dx+Ey+F=0，表示一個(gè)點(diǎn)(-D/2,-E/2)（3）當(dāng)D2+E2-4F0);
直線的一般式方程教學(xué)設(shè)計(jì)人教A版高中數(shù)學(xué)選擇性必修第一冊(cè)
解析:當(dāng)a0時(shí),直線ax-by=1在x軸上的截距1/a0,在y軸上的截距-1/a>0.只有B滿(mǎn)足.故選B.答案:B 3．過(guò)點(diǎn)(1,0)且與直線x－2y－2＝0平行的直線方程是( ) A．x－2y－1＝0 B．x－2y＋1＝0C．2x＋y＝2＝0 D．x＋2y－1＝0答案A 解析：設(shè)所求直線方程為x－2y＋c＝0，把點(diǎn)(1,0)代入可求得c＝－1.所以所求直線方程為x－2y－1＝0.故選A.4．已知兩條直線y＝ax－2和3x－(a＋2)y＋1＝0互相平行，則a＝________.答案：1或－3 解析：依題意得：a(a＋2)＝3×1，解得a＝1或a＝－3.5．若方程(m2－3m＋2)x＋(m－2)y－2m＋5＝0表示直線．(1)求實(shí)數(shù)m的范圍；(2)若該直線的斜率k＝1，求實(shí)數(shù)m的值．解析： (1)由m2－3m＋2＝0，m－2＝0，解得m＝2，若方程表示直線，則m2－3m＋2與m－2不能同時(shí)為0，故m≠2.(2)由－?m2－3m＋2?m－2＝1，解得m＝0.

人教版高中歷史必修2戰(zhàn)后資本主義的新變化說(shuō)課稿2篇
2.“里根經(jīng)濟(jì)學(xué)”和“撒切爾主義”20世紀(jì)70年代，世界資本主義經(jīng)濟(jì)發(fā)展進(jìn)入“滯脹”狀態(tài)后，各國(guó)政府紛紛尋找醫(yī)治這一新疾病的藥方，其中影響最大的是供應(yīng)學(xué)派和貨幣學(xué)派。1979年，撒切爾夫人上臺(tái)擔(dān)任英國(guó)首相，率先采納了貨幣學(xué)派的主張。1981年，里根擔(dān)任美國(guó)總統(tǒng)后，以供應(yīng)學(xué)派為依據(jù)，確立了自己政府的經(jīng)濟(jì)政策。由于兩人的經(jīng)濟(jì)政策都在一定程度上緩解了本國(guó)的經(jīng)濟(jì)危機(jī)，并有一套理論體系支撐，因此經(jīng)濟(jì)學(xué)家們分別稱(chēng)之為“里根經(jīng)濟(jì)學(xué)”和“撒切爾主義”。實(shí)際上，“里根經(jīng)濟(jì)學(xué)”和“撒切爾主義”有許多相同之處，二者都提倡自由放任，強(qiáng)調(diào)市場(chǎng)調(diào)節(jié)作用，反對(duì)國(guó)家干預(yù)；二者都實(shí)行有利于富人的減稅政策，因此都曾被攻擊為“劫貧濟(jì)富”；二者都大力增加軍費(fèi)開(kāi)支，用加大政府消費(fèi)來(lái)緩解危機(jī)。3.美國(guó)“新經(jīng)濟(jì)”戰(zhàn)后西方國(guó)家在凱恩斯主義指導(dǎo)下，暫時(shí)擺脫了三十年代那種嚴(yán)重的大蕭條局面，但由于長(zhǎng)期實(shí)行擴(kuò)張性財(cái)政貨幣政策和對(duì)社會(huì)需求進(jìn)行管理的政策，各資本主義國(guó)家經(jīng)濟(jì)又出現(xiàn)新的危機(jī)，即“滯脹”（生產(chǎn)停滯和通貨膨脹），凱恩斯主義由此走向沒(méi)落。

共享實(shí)驗(yàn)收集的信息，分享實(shí)驗(yàn)探究的結(jié)論，體驗(yàn)收獲的樂(lè)趣。 小結(jié)拓展 這節(jié)課由大家感興趣的球類(lèi)運(yùn)動(dòng)和彈弓游戲，提出了功與速度變化關(guān)系的問(wèn)題，利用倍增思想解決測(cè)量對(duì)物體做功的問(wèn)題，使用我們熟悉的器材設(shè)計(jì)了探究方案，并進(jìn)行實(shí)驗(yàn)探究，采用圖像法進(jìn)行數(shù)據(jù)處理，初步得出W∝V2的關(guān)系。在我們這節(jié)課探究以前，科學(xué)家就通過(guò)試驗(yàn)和理論的方法，已經(jīng)總結(jié)出了功與速度變化的定量關(guān)系。人類(lèi)社會(huì)也在社會(huì)生活和生產(chǎn)的各個(gè)領(lǐng)域予以利用。比如，古代的戰(zhàn)爭(zhēng)武器拋石器、大型弓弩，以及現(xiàn)代飛機(jī)彈射系統(tǒng)、還有機(jī)器人行走等等，希望同學(xué)在今后的學(xué)習(xí)中注意留心生活中的物理和社會(huì)中的物理。 領(lǐng)會(huì)總結(jié)。培養(yǎng)概括總結(jié)的能力，進(jìn)一步鞏固、感悟、提升實(shí)驗(yàn)探究中獲得的思維能力及動(dòng)手能力。感悟社會(huì)中的物理，認(rèn)識(shí)物理學(xué)對(duì)科技進(jìn)步以及文化和社會(huì)發(fā)展的影響。 列舉學(xué)生知道的社會(huì)中做功使物體速度變化的例子，增強(qiáng)學(xué)生將物理知識(shí)應(yīng)用于生活和生產(chǎn)的意識(shí)，培養(yǎng)學(xué)生的社會(huì)參與意識(shí)和對(duì)社會(huì)負(fù)責(zé)任的態(tài)度。
人教版高中地理必修1第二章第四節(jié)全球氣候變化說(shuō)課稿
（一）教材的地位與作用本節(jié)教材包括三方面的內(nèi)容，（1）全球氣候在不斷變化之中。（2）全球氣候變化的可能影響。（3）氣候變化的適應(yīng)對(duì)策三方面說(shuō)明氣候變化及其對(duì)人類(lèi)活動(dòng)的影響。從標(biāo)準(zhǔn)的要求看，學(xué)習(xí)的重點(diǎn)不在全球氣候變化本身，而是把全球氣候變化看作是客觀存在的事實(shí)，從而探討全球氣候變化對(duì)地理環(huán)境及人類(lèi)活動(dòng)的影響。從資料中可以看出本節(jié)教學(xué)內(nèi)容涵蓋的時(shí)空跨度非常大，思維的鏈索很長(zhǎng)很廣，許多問(wèn)題涉及到學(xué)科的前沿及人類(lèi)所關(guān)注的熱點(diǎn)，因此，本節(jié)課對(duì)學(xué)生而言既有趣味性，又有挑戰(zhàn)性。 （二）教學(xué)目標(biāo)(1)知識(shí)與技能目標(biāo)：1.通過(guò)全球氣候的長(zhǎng)期演變圖，學(xué)生了解全球氣候處在波動(dòng)變化之中。2.通過(guò)資料認(rèn)識(shí)全球氣候一直處于變化之中并呈現(xiàn)一定變化周期，了解全球氣候變化對(duì)地理環(huán)境及人類(lèi)活動(dòng)的影響，能夠提出一些氣候變化的適應(yīng)對(duì)策。
人教版高中歷史必修1世界多極化趨勢(shì)的出現(xiàn)說(shuō)課稿2篇
(一)本課教材地位分析本課教材的主題是世界格局多極化趨勢(shì)的出現(xiàn)，在整個(gè)單元中有承前啟后的作用,前一課是它的大背景,后一課是它的延續(xù)。本課的核心問(wèn)題是兩極格局下,20世紀(jì)六七十年代世界多極化趨勢(shì)的出現(xiàn)。通過(guò)走向聯(lián)合的歐洲、迅速崛起的日本、發(fā)展中國(guó)家的星期以及中國(guó)的崛起三方面內(nèi)容，反映了世界格局多極化趨勢(shì)的出現(xiàn)。在教學(xué)中，應(yīng)注意利用學(xué)生對(duì)時(shí)事的關(guān)心與熟悉，引導(dǎo)學(xué)生進(jìn)行相應(yīng)的探究活動(dòng)，使學(xué)生對(duì)世界格局的發(fā)展變化能夠認(rèn)識(shí)準(zhǔn)確和完整把握。（二）三維目標(biāo)A．知識(shí)與能力1.通過(guò)對(duì)歐洲一體化的進(jìn)程、日本經(jīng)濟(jì)迅速崛起、不結(jié)盟運(yùn)動(dòng)和中國(guó)振興的基本史實(shí)的學(xué)習(xí)，掌握20世紀(jì)六七十年代世界多極化趨勢(shì)出現(xiàn)的史實(shí)，理解其世界大背景和“多極化”的概念。2.通過(guò)西歐、日本、中國(guó)的崛起，理解經(jīng)濟(jì)決定政治，政治反作用于經(jīng)濟(jì)。
人教版高中生物必修1生物膜的流動(dòng)鑲嵌模型說(shuō)課稿
二、流動(dòng)鑲嵌模型的基本內(nèi)容1、膜的成分2、膜的基本支架3、膜的結(jié)構(gòu)特點(diǎn)4、膜的功能特性設(shè)計(jì)意圖：我根據(jù)板書(shū)的“規(guī)范、工整和美觀”的要求，結(jié)合所教的內(nèi)容，設(shè)計(jì)了如圖所示的板書(shū)，使學(xué)生對(duì)本節(jié)課有一個(gè)整體的思路。八、教學(xué)反思：本節(jié)課我創(chuàng)設(shè)了問(wèn)題情境來(lái)引導(dǎo)學(xué)生主動(dòng)學(xué)習(xí)，利用了多媒體信息技術(shù)激發(fā)學(xué)生的學(xué)習(xí)熱情，調(diào)動(dòng)了學(xué)生的積極性，成功實(shí)現(xiàn)預(yù)期的教學(xué)目標(biāo)。體現(xiàn)了學(xué)生為主體地位的新課程理念。啟發(fā)式、探究式的教學(xué)方法以及由教師指導(dǎo)下的學(xué)生自主閱讀、合作交流的學(xué)習(xí)方法把學(xué)生從死記知識(shí)的苦海中解救出來(lái)。初次的嘗試還存在一定的缺陷，學(xué)生不能夠很好的把知識(shí)和習(xí)題聯(lián)系，只是把他所知道的知識(shí)簡(jiǎn)單羅列，不能夠體現(xiàn)出能力的訓(xùn)練。在上課中發(fā)現(xiàn)學(xué)生比較靦腆或拘束，聲音比較小，表達(dá)不能到位。盡管本節(jié)課存在諸多不足之處，但是也讓我看到了閃光點(diǎn)：學(xué)生比較歡迎這樣一堂自己是主角的課堂。
