人教A版高中数学必修一单调性与最大（小）值教学设计（1）
《函数的单调性与最大（小）值}》系人教A版高中数学必修第一册第三章第二节的内容,本节包括函数的单调性的定义与判断及其证明、函数最大（小）值的求法。在初中学习函数时,借助图像的直观性研究了一些函数的增减性,这节内容是初中有关内容的深化、延伸和提高函数的单调性是函数众多性质中的重要性质之一,函数的单调性一节中的知识是前一节内容函数的概念和图像知识的延续,它和后面的函数奇偶性,合称为函数的简单性质,是今后研究指数函数、对数函数、幂函数及其他函数单调性的理论基础;在解决函数值域、定义域、不等式、比较两数大小等具体问需用到函数的单调性;同时在这一节中利用函数图象来研究函数性质的救开结合思想将贯穿于我们整个高中数学教学。
人教A版高中数学必修一用二分法求方程的近似解教学设计（1）
《数学1必修本（A版）》的第五章4.5.2用二分法求方程的近似解．本节课要求学生根据具体的函数图象能够借助计算机或信息技术工具计算器用二分法求相应方程的近似解，了解这种方法是求方程近似解的常用方法，从中体会函数与方程之间的联系；它既是本册书中的重点内容，又是对函数知识的拓展，既体现了函数在解方程中的重要应用，同时又为高中数学中函数与方程思想、数形结合思想、二分法的算法思想打下了基础，因此决定了它的重要地位．发展学生数学直观、数学抽象、逻辑推理和数学建模的核心素养。课程目标 学科素养1.通过具体实例理解二分法的概念及其使用条件．2.了解二分法是求方程近似解的常用方法，能借助计算器用二分法求方程的近似解．3.会用二分法求一个函数在给定区间内的零点，从而求得方程的近似解． a.数学抽象：二分法的概念；b.逻辑推理：运用二分法求近似解的原理；
人教版高中地理选修5中国的自然灾害教案
(3)2004年6月末至7月初，广东省出现罕见的大面积持续高温炎热天气，全省有45个县(市)的最高气温破历史同期记录。造成此次异常天气的主要原因是()A．副热带高压和热带气旋外围下沉气流共同影响B．大量使用汽车和制冷设备C．绿色植物呼吸作用释放CO：D．全球温室效应长期作用【解析】(1)根据“源于西太平洋洋面的台风”判断该台风属于北半球的气旋型的天气系统，当台风中心位于南海时，广东沿海地区正好位于该气旋的北部，故吹东北风。(2)夏秋季节的台风主要影响我国的南部、东部沿海地区，广东沿海正好位于该地区，受到的影响较大；广东沿海是我国经济非常发达的地区，富含有N、P、K等营养元素的工厂生产、农业生产、生活废水的排放导致海水中的藻类物质大量繁殖，水中的溶解氧减少，鱼类因窒息而死亡的现象在该地区时常发生。(3)从题干中提供的信息分析可知，6月末至7月初为北半球的夏季，因是短期的高温，与正常年份相比出现异常天气是因副热带高压和热带气旋外围下沉气流共同影响。

人教版高中地理选修2中、低产田的综合治理教案
一、低湿地的治理与开发1、 低湿地治理开发的原因——辛店洼自然条件的主要特点（1）地势低平：辛店洼洼底海拔17．5米，洼缘海拔19．5米，是全市最低点。（2）渍涝严重：其成因如表6-4所示（3）土质好、水源足、水质好：成土母质为黄河冲积物，土壤质地好；水资源丰富，水质较好。2、低洼地治理开发的方法：鱼塘——台田模式（或称塘田模式）以往辛店洼曾采用挖沟排水的措施治理低洼地，但治理效果不明显，因为辛店洼的主要矛盾是地势低洼，地下水位高，挖沟排水因地势低，排水困难，地下水位难以下降，故治理效果不明显。20世纪80年代以来，科学工作者在辛店洼地区开始了整治低湿地的研究，他们遵循“因洼制宜”的指导思想，逐步摸索出了低湿地的治理模式：鱼塘—--台田模式
人教版高中地理选修1第三章第一节地球的早期演化和地质年代教案
地质年代可分为相对年代和绝 对年龄（或同位素年龄）两种。相对地质年代是指岩石和地层之间的相对新老关系和它们的时代顺序。地质学家和古生物学家根据地层自然形成的先后顺序，将地层分为5代12纪。即早期的太古代和元古代（元古代 在中国含有1个震旦纪），以后的古生代、中生代和新生代。古生代分为寒武纪、奥陶纪、志留纪、泥盆纪、石炭纪和二叠纪，共7个纪；中生代分为三叠纪、侏罗纪和白垩纪，共3个纪；新生代只有第三纪、第四纪两个纪。在各个不同时期的地层里，大都保存有古代动、植物的标准化石。各类动、植物化石出现的早晚是有一定顺序的，越是低等的，出现得越早，越是高等的，出现得越晚。绝对年龄是根据测出岩石中某种放射性元素及其蜕变产物的含量而计算出岩石的生成后距今的实际年 数。越是老的岩石，地层距今的年数越长。

人教版高中数学选修3超几何分布教学设计
探究新知问题1：已知100件产品中有8件次品，现从中采用有放回方式随机抽取4件．设抽取的4件产品中次品数为X，求随机变量X的分布列.（1）：采用有放回抽样，随机变量X服从二项分布吗？采用有放回抽样，则每次抽到次品的概率为0.08，且各次抽样的结果相互独立,此时X服从二项分布,即X～B(4，0.08).（2）：如果采用不放回抽样，抽取的4件产品中次品数X服从二项分布吗？若不服从，那么X的分布列是什么？不服从，根据古典概型求X的分布列.解：从100件产品中任取4件有 C_100^4 种不同的取法，从100件产品中任取4件，次品数X可能取0,1,2,3,4.恰有k件次品的取法有C_8^k C_92^(4-k)种.一般地，假设一批产品共有N件，其中有M件次品．从N件产品中随机抽取n件(不放回），用X表示抽取的n件产品中的次品数，则X的分布列为P(X＝k）＝CkM Cn－kN－M CnN ，k＝m，m＋1，m＋2，…，r.其中n，N，M∈N*，M≤N，n≤N，m＝max{0，n－N＋M}，r＝min{n，M}，则称随机变量X服从超几何分布．

人教版高中政治选修3美国的联邦制教案
3、联邦制的弊端：（1）、效率不高：（2）、集团分享权力，维护资产阶级的利益，不顾人民要求。在美国实行联邦制的二百多年问，联邦制的弊端也显露无遗。美国联邦制的最大问题是效率不高，联邦政府与州政府之间相互扯皮、推诿，各州政府之间各自为政。全国性资产阶级利益集团与地方性资产阶级利益集团分享权力，对于广大人民群众的要求，资产阶级则利用国家结构形式的特点相互推卸责任。当大多数资产阶级利益集团意见接近时，联邦制既能保护州的灵活性，又能保证中央的权威；当资产阶级利益集团之间矛盾重重时，联邦制就处于低效运转之中。相关链接：1954年，美国最高法院在一项判决中宣布，公立学校实行种族隔离、拒绝黑人入学是违反宪法的。这一裁决引起南方一些州的抵制，一些州竟以暴力阻止黑人进入公立学校。
人教版高中政治选修3国际组织概观教案
4、中国积极发展与区域性国际组织的关系。中国积极发展与区域性国际组织的关系。中国与欧盟建立了领导人年度会晤机制，致力于发展全面战略伙伴关系。中国重视与非洲国家的传统友谊，与非洲联盟团结合作。中国与阿拉伯国家联盟、石油输出国组织等发展中国家组建的国际组织发展友好关系，支持它们维护自身的正当权益，并与它们共同为建立公正合理的国际政治经济新秩序而努力。新中国与国际组织关系的历史演变大致经历了三个时期。从中华人民共和国建立初期到1971年：新中国被排斥在联合国等国际组织之外，为恢复在联合国的合法席位进行了不懈的斗争。从1 9 7 1年到改革开放前：中国恢复了在联合国的合法席位，并与大批国际组织建立、恢复了友好合作关系。改革开放以来：中国恢复了在世界银行和国际货币基金组织的席位，加入了世界贸易组织、亚太经合组织等经济组织。世界银行出资兴建的希望小学小结：4个主要特征：国际组织的四个主要特征即：①跨国性、②目的性、③组织性、④自主性。

①含义：即国家管理形式，是国家政权的组织形式②政体的必要性和重要性A、行使职能B、维护其根本利益掌握国家政权的阶级为实现政治统治、行使社会管理职能，必然要采取某种形式组织政权机关。统治阶级为维护其根本利益，总是力求采用最有效的政权组织形式。3、国体与政体的关系（板书）（1）、政体的多样性（2）、国体与政体的关系①国体决定政体，并通过一定的政体来体现；政体体现国体，并服务于特定的国体。适当的政体能够巩固国体，不适当的政体会危害国体。补充：政体由国体决定并反映国体，国体是主要的方面。但是，政体也具有一定的独立性，影响它形成的因素主要有：历史条件、阶级力量对比、传统习惯、国际环境影响等。②专政政体国体与政体，即是国家制度中内容与形式两个方面(3)从国体、政体两个方面看民主制国家补充：专政即是主要依靠暴力实行的统治，它与民主相对立，属于国体的范畴，而专制则与法制相对立，属于政体的范畴。
人教版高中政治选修3美国的利益集团教案
（3）、各种利益集团内部很少有什么民主机制，大都为少数人所控制——从利益集团内部的管理机制看；广大群众常常对某些组织寄予期望，投人力量，但是他们的利益却往往得不到关注。（4）、利益集团为政府腐败提供了肥沃的土壤。利益集团的活动方式，在很大程度上是用金钱购买政治影响力，是一种滋养腐败的行为——从利益集团对政府的负面影响看。实际上，在国会议员、政府官员与利益集团之间，已经形成一种相互依赖的共生关系。3、利益集团机制的隐蔽性、欺骗性及其实质：美国政坛中的利益集团机制，是资产阶级控制国家机器的一种特殊形式，具有相当强的隐蔽性和欺骗性。表面上看，利益集团是所谓的“民意代表”，向政府反映各阶层、群体的观点和利益，实质上是资产阶级在“民意”的幌子下控制权力。
