初中數(shù)學(xué)浙教版七年級下冊《第二章 二元一次方程組 三元一次方程組及其解法》教材教案
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。
北師大初中九年級數(shù)學(xué)下冊二次函數(shù)y=ax2+bx+c的圖象與性質(zhì)1教案
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).
