知識與技能目標(biāo):1. 能正確說出三元一次方程(組)及其解的概念,能正確判別一組數(shù)是否是三元一次方程(組)的解;2. 會根據(jù)實(shí)際問題列出簡單的三元一次方程或三元一次方程組。過程與方法目標(biāo):1. 通過加深對概念的理解,提高對“元”和“次”的認(rèn)識。2. 能夠逐步培養(yǎng)類比分析和歸納概括的能力,了解辯證統(tǒng)一的思想。情感態(tài)度與價(jià)值觀目標(biāo):通過對實(shí)際問題的分析,使學(xué)生進(jìn)一步體會方程是刻畫現(xiàn)實(shí)世界的有效數(shù)學(xué)模型,培養(yǎng)學(xué)生良好的數(shù)學(xué)應(yīng)用意識。
解析:(1)已知拋物線解析式y(tǒng)=ax2+bx+0.9,選定拋物線上兩點(diǎn)E(1,1.4),B(6,0.9),把坐標(biāo)代入解析式即可得出a、b的值,繼而得出拋物線解析式;(2)求出y=1.575時(shí),對應(yīng)的x的兩個(gè)值,從而可確定t的取值范圍.解:(1)由題意得點(diǎn)E的坐標(biāo)為(1,1.4),點(diǎn)B的坐標(biāo)為(6,0.9),代入y=ax2+bx+0.9,得a+b+0.9=1.4,36a+6b+0.9=0.9,解得a=-0.1,b=0.6.故所求的拋物線的解析式為y=-0.1x2+0.6x+0.9;(2)157.5cm=1.575m,當(dāng)y=1.575時(shí),-0.1x2+0.6x+0.9=1.575,解得x1=32,x2=92,則t的取值范圍為32<t<92.方法總結(jié):解答本題的關(guān)鍵是注意審題,將實(shí)際問題轉(zhuǎn)化為求函數(shù)問題,培養(yǎng)自己利用數(shù)學(xué)知識解答實(shí)際問題的能力.三、板書設(shè)計(jì)二次函數(shù)y=ax2+bx+c的圖象與性質(zhì)1.二次函數(shù)y=ax2+bx+c的圖象與性質(zhì)2.二次函數(shù)y=ax2+bx+c的應(yīng)用
(3)設(shè)點(diǎn)A的坐標(biāo)為(m,0),則點(diǎn)B的坐標(biāo)為(12-m,0),點(diǎn)C的坐標(biāo)為(12-m,-16m2+2m),點(diǎn)D的坐標(biāo)為(m,-16m2+2m).∴“支撐架”總長AD+DC+CB=(-16m2+2m)+(12-2m)+(-16m2+2m)=-13m2+2m+12=-13(m-3)2+15.∵此二次函數(shù)的圖象開口向下,∴當(dāng)m=3米時(shí),“支撐架”的總長有最大值為15米.方法總結(jié):解決本題的關(guān)鍵是根據(jù)圖形特點(diǎn)選取一個(gè)合適的參數(shù)表示它們,得出關(guān)系式后運(yùn)用函數(shù)性質(zhì)來解.三、板書設(shè)計(jì)二次函數(shù)y=a(x-h(huán))2+k的圖象與性質(zhì)1.二次函數(shù)y=a(x-h(huán))2+k的圖象與性質(zhì)2.二次函數(shù)y=a(x-h(huán))2+k的圖象與y=ax2的圖象的關(guān)系3.二次函數(shù)y=a(x-h(huán))2+k的應(yīng)用要使課堂真正成為學(xué)生展示自我的舞臺,還學(xué)生課堂學(xué)習(xí)的主體地位,教師要把激發(fā)學(xué)生學(xué)習(xí)熱情和提高學(xué)生學(xué)習(xí)能力放在教學(xué)首位,為學(xué)生提供展示自己聰明才智的機(jī)會,使課堂真正成為學(xué)生展示自我的舞臺.充分利用合作交流的形式,能使教師發(fā)現(xiàn)學(xué)生分析問題、解決問題的獨(dú)到見解以及思維的誤區(qū),以便指導(dǎo)今后的教學(xué).
雨后天空的彩虹、河上架起的拱橋等都會形成一條曲線.問題1:這些曲線能否用函數(shù)關(guān)系式表示?問題2:如何畫出這樣的函數(shù)圖象?二、合作探究探究點(diǎn):二次函數(shù)y=x2和y=-x2的圖象與性質(zhì)【類型一】 二次函數(shù)y=x2和y=-x2的圖象的畫法及特點(diǎn)在同一平面直角坐標(biāo)系中,畫出下列函數(shù)的圖象:(1)y=x2;(2)y=-x2.根據(jù)圖象分別說出拋物線(1)(2)的對稱軸、頂點(diǎn)坐標(biāo)、開口方向及最高(低)點(diǎn)坐標(biāo).解析:利用列表、描點(diǎn)、連線的方法作出兩個(gè)函數(shù)的圖象即可.解:列表如下:x y) -2 -1 0 1 2y=x2 4 1 0 1 4 y=-x2 -4 -1 0 -1 -4 描點(diǎn)、連線可得圖象如下:(1)拋物線y=x2的對稱軸為y軸,頂點(diǎn)坐標(biāo)為(0,0),開口方向向上,最低點(diǎn)坐標(biāo)為(0,0);(2)拋物線y=-x2的對稱軸為y軸,頂點(diǎn)坐標(biāo)為(0,0),開口方向向下,最高點(diǎn)坐標(biāo)為(0,0).方法總結(jié):畫拋物線y=x2和y=-x2的圖象時(shí),還可以根據(jù)它的對稱性,先用描點(diǎn)法描出拋物線的一側(cè),再利用對稱性畫另一側(cè).
變式訓(xùn)練:見《學(xué)練優(yōu)》本課時(shí)練習(xí)“課堂達(dá)標(biāo)訓(xùn)練”第5題【類型二】 在同一坐標(biāo)系中判斷二次函數(shù)和一次函數(shù)的圖象在同一直角坐標(biāo)系中,一次函數(shù)y=ax+c和二次函數(shù)y=ax2+c的圖象大致為()解析:∵一次函數(shù)和二次函數(shù)都經(jīng)過y軸上的點(diǎn)(0,c),∴兩個(gè)函數(shù)圖象交于y軸上的同一點(diǎn),故B選項(xiàng)錯(cuò)誤;當(dāng)a>0時(shí),二次函數(shù)的圖象開口向上,一次函數(shù)的圖象從左向右上升,故C選項(xiàng)錯(cuò)誤;當(dāng)a<0時(shí),二次函數(shù)的圖象開口向下,一次函數(shù)的圖象從左向右下降,故A選項(xiàng)錯(cuò)誤,D選項(xiàng)正確.故選D.方法總結(jié):熟記一次函數(shù)y=kx+b在不同情況下所在的象限,以及熟練掌握二次函數(shù)的有關(guān)性質(zhì)(開口方向、對稱軸、頂點(diǎn)坐標(biāo)等)是解決問題的關(guān)鍵.變式訓(xùn)練:見《學(xué)練優(yōu)》本課時(shí)練習(xí)“課后鞏固提升” 第4題【類型三】 二次函數(shù)y=ax2+c的圖象與三角形的綜合
三、教學(xué)建議第一課時(shí):1. Lead in (Vocabulary)A) Before class, teacher should collect some pictures of working places. For example: Bank, TV Station, Restaurant, Police Station, Hospital ...B) In class, show students the pictures (PowerPoint, OHP). Ask students to tell the name of the working places and the name of the jobs.Shop assistant, doctor, actor, reporter, police office, waiter, bank clerk, studentC) Do exercise 1a and 3a.2. Bingo GameAsk groups of students to make up pairs of cards with a job on one and the related workplace on the other. For example, waiter / restaurant, teacher / school, doctor / hospital. Encourage students to use both the job / workplace combinations in the book and the ones that students came up during class discussions. Be sure they have twice as many sets of cards as there are students in the group. They can make two sets of cards for a single job / workplace, if necessary. Then have each group mix up its set of cards and hand their cards out in random order. Each time a student gets a pair of cards that match, he or she can lay these cards down. The goal is to have no cards in your hand at the end.3. Task OneA) Ask students to work in pairs and ask the partner what does he / she want to be in the future.e. g. :What do you / does he / does she want to be?I want to be a.Why?Because it's (adj).B) Vocabulary: Section B, 1a4.
