圆的一般方程教学设计人教A版高中数学选择性必修第一册
情境导学前面我们已讨论了圆的标准方程为(x-a)2+(y-b)2=r2,现将其展开可得：x2+y2-2ax-2bx+a2+b2-r2=0.可见,任何一个圆的方程都可以变形x2+y2+Dx+Ey+F=0的形式.请大家思考一下,形如x2+y2+Dx+Ey+F=0的方程表示的曲线是不是圆?下面我们来探讨这一方面的问题.探究新知例如,对于方程x^2+y^2-2x-4y+6=0,对其进行配方，得〖(x-1)〗^2+(〖y-2)〗^2=-1,因为任意一点的坐标 (x,y) 都不满足这个方程，所以这个方程不表示任何图形，所以形如x2+y2+Dx+Ey+F=0的方程不一定能通过恒等变换为圆的标准方程，这表明形如x2+y2+Dx+Ey+F=0的方程不一定是圆的方程.一、圆的一般方程（1）当D2+E2-4F>0时,方程x2+y2+Dx+Ey+F=0表示以(-D/2,-E/2)为圆心,1/2 √(D^2+E^2 "-" 4F)为半径的圆,将方程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）当D2+E2-4F=0时,方程x2+y2+Dx+Ey+F=0，表示一个点(-D/2,-E/2)（3）当D2+E2-4F0);
直线的点斜式方程教学设计人教A版高中数学选择性必修第一册
【答案】B [由直线方程知直线斜率为3，令x＝0可得在y轴上的截距为y＝－3.故选B.]3．已知直线l1过点P(2,1)且与直线l2：y＝x＋1垂直，则l1的点斜式方程为________．【答案】y－1＝－(x－2) [直线l2的斜率k2＝1，故l1的斜率为－1，所以l1的点斜式方程为y－1＝－(x－2)．]4．已知两条直线y＝ax－2和y＝(2－a)x＋1互相平行，则a＝________. 【答案】1 [由题意得a＝2－a，解得a＝1.]5.无论k取何值,直线y-2=k(x+1)所过的定点是 . 【答案】(-1,2)6．直线l经过点P(3,4)，它的倾斜角是直线y＝3x＋3的倾斜角的2倍，求直线l的点斜式方程．【答案】直线y＝3x＋3的斜率k＝3，则其倾斜角α＝60°，所以直线l的倾斜角为120°.以直线l的斜率为k′＝tan 120°＝－3.所以直线l的点斜式方程为y－4＝－3(x－3)．
直线的两点式方程教学设计人教A版高中数学选择性必修第一册
解析：①过原点时，直线方程为y＝－34x.②直线不过原点时，可设其方程为xa＋ya＝1，∴4a＋－3a＝1，∴a＝1.∴直线方程为x＋y－1＝0.所以这样的直线有2条，选B.答案：B4.若点P(3,m)在过点A(2,-1),B(-3,4)的直线上,则m= . 解析:由两点式方程得,过A,B两点的直线方程为(y"-(-" 1")" )/(4"-(-" 1")" )=(x"-" 2)/("-" 3"-" 2),即x+y-1=0.又点P(3,m)在直线AB上,所以3+m-1=0,得m=-2.答案:-2 5.直线ax+by=1(ab≠0)与两坐标轴围成的三角形的面积是 . 解析:直线在两坐标轴上的截距分别为1/a 与 1/b,所以直线与坐标轴围成的三角形面积为1/(2"|" ab"|" ).答案:1/(2"|" ab"|" )6.已知三角形的三个顶点A(0,4)，B(－2,6)，C(－8,0)．(1)求三角形三边所在直线的方程；(2)求AC边上的垂直平分线的方程．解析(1)直线AB的方程为y－46－4＝x－0－2－0，整理得x＋y－4＝0；直线BC的方程为y－06－0＝x＋8－2＋8，整理得x－y＋8＝0；由截距式可知，直线AC的方程为x－8＋y4＝1，整理得x－2y＋8＝0.(2)线段AC的中点为D(－4,2)，直线AC的斜率为12，则AC边上的垂直平分线的斜率为－2，所以AC边的垂直平分线的方程为y－2＝－2(x＋4)，整理得2x＋y＋6＝0.
直线的一般式方程教学设计人教A版高中数学选择性必修第一册
解析:当a0时,直线ax-by=1在x轴上的截距1/a0,在y轴上的截距-1/a>0.只有B满足.故选B.答案:B 3．过点(1,0)且与直线x－2y－2＝0平行的直线方程是( ) A．x－2y－1＝0 B．x－2y＋1＝0C．2x＋y＝2＝0 D．x＋2y－1＝0答案A 解析：设所求直线方程为x－2y＋c＝0，把点(1,0)代入可求得c＝－1.所以所求直线方程为x－2y－1＝0.故选A.4．已知两条直线y＝ax－2和3x－(a＋2)y＋1＝0互相平行，则a＝________.答案：1或－3 解析：依题意得：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表示直线．(1)求实数m的范围；(2)若该直线的斜率k＝1，求实数m的值．解析： (1)由m2－3m＋2＝0，m－2＝0，解得m＝2，若方程表示直线，则m2－3m＋2与m－2不能同时为0，故m≠2.(2)由－?m2－3m＋2?m－2＝1，解得m＝0.
用空间向量研究距离、夹角问题（1）教学设计人教A版高中数学选择性必修第一册
二、探究新知一、点到直线的距离、两条平行直线之间的距离1.点到直线的距离已知直线l的单位方向向量为μ,A是直线l上的定点,P是直线l外一点.设(AP) ?=a,则向量(AP) ?在直线l上的投影向量(AQ) ?=(a·μ)μ.点P到直线l的距离为PQ=√(a^2 "-(" a"·" μ")" ^2 ).2.两条平行直线之间的距离求两条平行直线l,m之间的距离,可在其中一条直线l上任取一点P,则两条平行直线间的距离就等于点P到直线m的距离.点睛：点到直线的距离,即点到直线的垂线段的长度,由于直线与直线外一点确定一个平面,所以空间点到直线的距离问题可转化为空间某一个平面内点到直线的距离问题.1.已知正方体ABCD-A1B1C1D1的棱长为2,E,F分别是C1C,D1A1的中点,则点A到直线EF的距离为 . 答案: √174/6解析:如图,以点D为原点,DA,DC,DD1所在直线分别为x轴、y轴、z轴建立空间直角坐标系,则A(2,0,0),E(0,2,1),F(1,0,2),(EF) ?=(1,-2,1),

（三）教学重、难点1、教学重点：结合课文，了解演讲辞针对性强、条理清楚、通俗易懂、适当的感情色彩等特点。2、教学难点：深入理解文章内涵，联系现实，体会本文的现实意义二、说学情高中学生在初中阶段已经接触过演讲辞了，对演讲词的特点已经有了一些基本的知识，因此本轮的教学应该让他们在此基础上有所提高。本文是学生在高中阶段第一次接触演讲辞，有必要让他们了解演讲辞的特点及课文如何体现这些特点的。随着年龄的增长，生活阅历的增加，高中学生正逐渐形成自己对世界、对人生的看法，蔡元培先生的这篇文章能很好地激发他们对当前的高中学习和未来的大学生活进行思考。此外，学生对北大的历史及蔡元培先生作这番演讲的时代背景了解不深，应作出补充说明。
人教版高中历史必修3物理学的重大进展说课稿2篇
二、相对论的创立【课件】展示下列材料艾伯特·爱因斯坦（1879——1955），1879年3月14日诞生在德国乌尔姆的一个犹太人家中。1894年举家迁居意大利米兰。1900年毕业于瑞士苏黎世工业大学。爱因斯坦被认为是最富于创造力的科学家，他不但创立了相对论，还提出了光量子的概念，得出了光电效应的基本定律，并揭示了光的波粒二重性本质，为量子力学的建立奠定基础。为此荣获1921年度的诺贝尔物理学奖。同时，他还证明了热的分子运动论，提出了测定分子大小的新方法。【问题】19世纪末20世纪初爱因斯坦对物理学的贡献是什么？意义是什么？为什么会出现？1、背景：经典物理学的危机。19世纪末三大发现：x射线、放射性和电子，经典力学无法解释研究中的新问题，如：黑体辐射、光电效应等。2、相对论的提出及主要内容：（1）“狭义相对论”和光速不变原理：1905年提出。
人教版高中历史必修2战后资本主义的新变化说课稿2篇
2.“里根经济学”和“撒切尔主义”20世纪70年代，世界资本主义经济发展进入“滞胀”状态后，各国政府纷纷寻找医治这一新疾病的药方，其中影响最大的是供应学派和货币学派。1979年，撒切尔夫人上台担任英国首相，率先采纳了货币学派的主张。1981年，里根担任美国总统后，以供应学派为依据，确立了自己政府的经济政策。由于两人的经济政策都在一定程度上缓解了本国的经济危机，并有一套理论体系支撑，因此经济学家们分别称之为“里根经济学”和“撒切尔主义”。实际上，“里根经济学”和“撒切尔主义”有许多相同之处，二者都提倡自由放任，强调市场调节作用，反对国家干预；二者都实行有利于富人的减税政策，因此都曾被攻击为“劫贫济富”；二者都大力增加军费开支，用加大政府消费来缓解危机。3.美国“新经济”战后西方国家在凯恩斯主义指导下，暂时摆脱了三十年代那种严重的大萧条局面，但由于长期实行扩张性财政货币政策和对社会需求进行管理的政策，各资本主义国家经济又出现新的危机，即“滞胀”（生产停滞和通货膨胀），凯恩斯主义由此走向没落。

（2）理解诗意。（告诉方法，引导自学）①同学们通过诗题就知道了诗的内容了，太棒了，谁能告诉我诗人会看到什么样的景象？（指名回答，学生互相补充纠正）明确：瑟瑟（形容未受到残阳照射的江水呈现的青绿色）、可怜（可爱）、真珠（珍珠）②同学们描述的都很漂亮，我们在翻译诗句意思的时候一定要跟诗句结合起来，不能增加诗中没有的内容，也不能删减诗中原有的内容。在这个基础上，谁能再说说诗句的意思？（指名答，课件展示） ③白居易在诗中这么描绘，是不是真实的呢？有同学说真实，因为真的见到过这样的景象，也有同学表示不理解，很棒，学贵质疑，我们来看看这些图片，说说我们的老朋友写的准不准确？（课件展示） （3）分析诗歌。（引导提示） ①引导背诵。合上课本，我们现在跟着白居易一起，我们在傍晚的时候来到了江边，首先看到了什么？用诗句回答（一道残阳铺水中），我们往下看江面，江面的景象是什么样的？（半江瑟瑟半江红），这样的场面让我们留恋了一会，太阳下去了，夜晚到来了，我们欣赏着风光，觉得这夜晚怎么样？（可怜九月初三夜），可爱的夜晚，露水晶莹像珍珠，月儿弯弯像弓，诗人脱口而出（露似真珠月似弓）。
（新）部编人教版四年级上册《古诗三首》（一）说课稿（二）
一、说教材：对于《题西林壁》这篇课文，我是这样解读的：《题西林壁》是一首哲理诗，作者通过描写游览庐山的经历，总结出观察问题应客观全面，如果主观片面，就得不出正确的结论的道理。二、说学情：对于学生的情况，我是这样认为的：四年级的学生，他们的思维以具象思维为主，因此他们对于文中描写的景物有自己的感触。但是他们抽象思维能力较弱，而本诗又是一首哲理诗，学生在理解上有一定的难度，这就需要教师加以引导。除此之外，学生的有意注意力和稳定性还是较差的，所以教师在教学过程中要运用多媒体、图片等来增强教学的直观性、形象性，以吸引学生的注意力。

第三，说教学重点和难点。根据课程标准的具体要求、学生实际和社会实际以及教材的逻辑结构和教学体系，我认为本课的重难点是以下几个方面。教学重点：1．理解王昭君的形象2．深入理解杜甫在诗中的情感教学难点：理解寓意，把握主旨。第四，说教法与学法。教法：根据课文特点和学生实际情况，以诵读法（示范朗读、学生齐读）、问题探究法、点拨法、讨论分析法进行教学。首先激发学生学习本文的兴趣；然后引导学生反复吟哦诵读，在读的过程中质疑、思考、品析、鉴赏；最后在教师适当的点拨下，在集体的热烈讨论中，理解作者的感情，得到新的认识。（解说：使学生在教师的主导下围绕中心议题发表各自的意见，相互交流，相互启发，相互争议，激发他们主动去获取知识，培养健康情感。）

在学生正确掌握了三民主义的进步性和局限性之后，提出第五个问题：三民主义的局限性是由什么决定的？这一问题学生较易回答，为进入下一目教学打下基础。二、三民主义的实践这目内容在新课导入时已经涉及，故进行略讲，主要采用谈话法，与学生一起回忆、交流。在此基础上，提出探究问题五：在三民主义指导下，孙中山先生进行的一系列革命斗争其结局怎样？为什么会这样？第一问学生较易回答，第二问我组织学生进行交流、讨论。在学生回答的基础上，我将向学生指出：由于三民主义的局限性，它不能指导中国民主革命走向成功，中国革命呼唤新的理论指导。从而过渡到下一目教学。三、旧三民主义发展为新三民主义1、背景：情境再现，激发兴趣分析资料，感悟新知多媒体播放电影《孙中山》片段让学生感受在一系列革命斗争失败后，孙中山先生的彷徨、思索。
人教版高中语文必修3《杜甫诗三首 秋兴八首》说课稿2篇
师：“两开”是什么意思啊？注解里是怎么说的？第二次开，也就说他在这个地方已经待了两年了，这里是他回家的路途中，是不是？路途中他停留了两年时间。好的，你先请坐。你觉得残菊不能两开，在理解上好像存在一些误差。赵勇：因为菊花古往今来代表着对家乡的思念。师：菊花代表对家乡的思念？（下面学生齐笑）这种说法牵强了些，菊花在古代象征着高洁，梅兰竹菊是四君子嘛。赵勇：写这首诗时，他已经打算回故乡了，所以不应该写“残菊”，写“残菊”的话……师：事实上，他回不了故乡。好的，请坐。再想想，“残菊”意味着什么？破败。“丛菊”呢？茂盛。那这里说“两开他日泪”，“两开”是什么意思？开了两了次了，这说明他在这里已经待了两年了。那“他日泪”又是什么意思？赵勇：应该是他看到这里的菊花开得这么茂盛，就想到了故乡的菊花也是开的茂盛的时候。如果是“残菊”的话，那故乡的菊也会开得很残败。（下面学生齐笑）
