人教版高中地理必修2从市中心到郊区，你选择住哪里说课稿
课前活动：分成四组，对南京三个住房地段进行调查，新街口夫子庙、板仓、仙林，对住房居民进行问卷调查，自行设计调查问卷，分析该地段的房价要求，居民的要求，居民为何要在该地段购买住房，基础设施设置等等其它与居民购房有关的因素。◆设计意图：利用课前小组探究形式对所学问题进行相关调查，不仅让学生掌握知识了解知识来源于社会还能培养学生深入生活交际表达能力以及合作探究能力；3.问题设计同学们，不知道你们在调查过程中是否发现一个问题，郊区的房子，特别是别墅，都是些高档居所，许多有钱人的居住场所，那为什么会这样呢？伴随着城市化进程中居民都往城里挤，为什么还会有许多有钱人往郊区搬呢？这就是我们今天要研究的第二个问题：逆城市化。◆设计意图：承转过渡知识，从购房选择因素的学习过渡到郊区化的学习，同时培养学生发现问题的能力，给学生以启迪。
人教版新课标高中物理必修2验证机械能守恒定律说课稿
一、 教材分析与学情分析教材分析人民教育出版社普通高中课程标准实验教科书必修2第七章第九节。本节内容安排在学习机械能守恒定律之后的目的，是为了使学生在理论上对机械能守恒定律有所了解的基础上，通过实验测量及对实验数据的分析处理，对机械能守恒定律及条件有深刻的认识。学情分析知识层面：学生已经掌握了动能、重力势能等概念以及动能定理、机械能守恒定律等定理、定律；知道功是能量转换的量度以及机械能守恒的条件。能力层面：学生已具备一定的实验操作技能，会用打点计时器以及直尺等实验仪器。具备一定的数据处理能力。二、教学目标与重点、难点教学目标知识与技能：1、会用打点计时器打下的纸带计算物体运动的速度。2、掌握验证机械能守恒定律的实验原理。
人教版新课标高中物理必修2向心加速度说课稿
d．某物体沿直线向东运动，原来的速度是5m/s，2s后速度减小到3m/s，求2s内物体速度变化。④如何探究物体作匀速圆周运动时，在Δt时间内的速度变化？分析：有了同一直线上速度变化的铺垫后，讨论物体做匀速圆周运动速度的变化就比较自然了，为了给向心加速度方向的学习打好基础，可以通过小组协作，进一步完成下列思考题，使同学们认识到：时间间隔起短，速度变化的方向起接近半径方向。（多媒体屏幕投影）a．物体沿半径为1m的轨道做匀速圆周运动，线速度大小为，求1s内物体速度变化并画出1s内速度变化的示意图。b．分别求出上题中物体在0.5s、0.25s内速度变化并画出相应的示意图。由于没有办法直接利用实验来验证速度变化的方向，所以，我们采用提供思考题的方法，引导同学在合作学习、自主探究中完成。有了速度变化的研究为铺垫，加速度的方向问题就迎刃而解了。
人教版高中生物必修2基因突变和基因重组说课稿
1、教材内容本节是人教版普通高中标准实验教科书生物必修2《遗传与进化》的第五章《基因突变及其他变异》的第一节内容。本节介绍了可遗传变异的两种类型：基因突变和基因重组，其中基因突变从实例对镰刀型细胞贫血症的分析入手，引入基因突变的概念，然后详细阐述基因突变的原因和特点、意义。在阐述自然状态下基因突变的频率很低时，教材用实例说明在一个足够大的群体中，即使基因突变频率很低，突变个体仍然会占有一定的数量。这个实例体现了生物在进化过程中“变”与“不变”的平衡，有助于学生理解基因突变在生物进化中所占有的重要地位。在基因重组部分，教材设置了“思考与讨论“的栏目，旨在让学生利用数学方法，通过计算，体会基因重组机制提供的极其多样的基因组合方式，从而帮助学生理解基因重组是生物多样性形成的主要原因。正文中则简要阐述了基因重组的概念、类型和意义。本节内容引导学生从分子水平上理解遗传物质如何引起生物变异的。
人教版高中生物必修2减数分裂和受精作用说课稿
一 减数分裂高一生物减数分裂说课稿各位评委、老师：大家好，我今天说课的题目是高中生物必修2第二章第一节〈〈减数分裂与受精作用〉〉第一部分减数分裂第一课时精子形成过程。接下来我就从以下几个方面来说说这一节课。一、说教材1．教材地位和作用《减数分裂》这一部分内容不仅是第二章的重点内容，也是整本书的重点内容之一。它以必修一学过的细胞学知识、染色体知识、有丝分裂知识和初中生殖种类知识为基础。通过学习，使学生全面认识细胞分裂的种类、实质和意义，为后面学习遗传和变异，生物的进化奠定细胞学基础。2．教学目标（1）知识目标：掌握减数分裂的概念和精子的形成过程；理解减数分裂和受精作用的意义。（2）能力目标：通过观察减数分裂过程中染色体的行为变化，培养学生识图、绘图能力以及比较分析和归纳总结的能力。

人教版高中地理必修2第二章第一节城市内部空间结构说课稿
提问：结合课本找出城市地域结构模式的类型及各自特点，模式形成的因素又有哪些？学生回答，使其掌握基本模式及特点，通过对比，分析把握每一模式各自的特征，学会把握事物本质。◆设计意图：阅读课本，总结归纳，同时引导，通过原因规律的探究，大胆设想，总结规律掌握人文地理学习思路。4.活动设计：内部空间结构变化，结合实例，分析说明。提问：结合江宁区的变化，分析江宁区城市结构发生了哪些变化？结合课本24页活动题，提出功能结构布局方案？通过理论联系实际，让学生更好理解理论，掌握城市结构布局的变化及其影响因素，通过活动题方案的提出，学生能够掌握布局的规律性，解决问题。设计意图：理论联系实际，知识的不枯燥性，提高学生学习兴趣。同时，能够通过总结，深层次认识城市结构布局，活学活用。
人教版高中地理必修2第四章第三节传统工业区与新工业区说课稿
下面是对以高技术产业为主的新工业区的内容进行讲解，教材以美国“硅谷”为例，首先谈的是高技术工业的特点，然后讲述的是“硅谷”的发展条件，由于教学模式与意大利新工业区的内容基本一致，这里就不再赘述了。接下来教材中提到的与之对照的案例同样是以高技术产业而闻名的中关村，由于中关村在国内的知名度较高，一般学生都有所了解，因此不妨让学生谈谈自己的看法：对于高新技术产业的发展有何建议，相对于发展较为成功的“硅谷”我们需要学习的方面又是哪些？案例中最后一个问题很值得深省，我国的新工业区到底怎样做才能够获得成功，简单的模仿下我们缺少的又是什么？这个问题可以作为拓展，让学生写一篇简短的论文作为课后作业。最后做以简单的课堂小结。本节内容的教学可能会相对繁杂，而案例之间的分析过程又过于雷同，所以难免枯燥。在处理这个问题上，我将尽量做到详略得当，主要培养学生的自主学习能力。
人教版高中地理必修1全球气候变化教案
科学家预测，就地区而言，位于低纬度的大部分国家，农作物的产量将减少；而位于高纬度的国家，农作物产量有可能增加。由于不少发展中国家位于低纬度地区，因此，气候变化的这种区域差异性，可能会使发展中国家所面临的问题更为严峻。板书：3全球变暖将加剧水资源的不稳定性与供需矛盾。介绍：全球变暖会影响整个水循环过程，可能使蒸发加大，改变区域降水量和降水分布格局，增加降水极端异常事件的发生，导致洪涝、干旱灾害的频次和强度增加，以及地表径流发生变化。随着径流减少，蒸发增强，全球变暖将加剧水资源的不稳定性与供需矛盾。转折：既然全球变暖会引起很多不利影响，那么作为人类应如何面对这一挑战呢？这就是我们要讨论的第三个问题。板书：三、气候变化的适应对策讨论：请大家阅读结合教材P53气候变化的适应对策部分讨论人类应如何面对全球变暖这一问题 呢？
