（一）教材的地位与作用本节教材包括三方面的内容，（1）全球气候在不断变化之中。（2）全球气候变化的可能影响。（3）气候变化的适应对策三方面说明气候变化及其对人类活动的影响。从标准的要求看，学习的重点不在全球气候变化本身，而是把全球气候变化看作是客观存在的事实，从而探讨全球气候变化对地理环境及人类活动的影响。从资料中可以看出本节教学内容涵盖的时空跨度非常大，思维的链索很长很广，许多问题涉及到学科的前沿及人类所关注的热点，因此，本节课对学生而言既有趣味性，又有挑战性。 （二）教学目标(1)知识与技能目标：1.通过全球气候的长期演变图，学生了解全球气候处在波动变化之中。2.通过资料认识全球气候一直处于变化之中并呈现一定变化周期，了解全球气候变化对地理环境及人类活动的影响，能够提出一些气候变化的适应对策。
人教版高中政治必修4价值判断和价值选择说课稿（一）
2．讲授新课：（约35分钟）结合教材内容重难点和学生实际，在讲课过程中，我对教材内容的顺序进行了重组，把教材内容由原来的两大部分划分为三大部分（第一，价值判断和价值选择的含义和关系；第二，价值判断和价值选择的特征；第三，做出正确的价值判断和价值选择的标准）。这一调整更符合学生的认知结构，便于从整体上把握课本内容。在讲授过程中，我充分利用课本素材——探究活动为课堂教学服务，此外，利用学生的生活与体验，挖掘实例，如结婚要礼由以前的旧三件到现如今的转变，引导学生理解价值判断和价值选择的社会历史性特征，以以《观祈雨》、以医生、艺术家、老学究对于《断臂的维纳斯》这个雕塑的不同见解、以新鲜实例韩国沉船事件和范跑跑为例启发学生价值判断和价值选择具有主体差异性特征以此突破难点，最后通过设疑、对比、追问正确的价值判断和价值选择的标准来深化主题，突出重点。3．课堂小结：（约2分钟）强化认识
人教版高中政治必修2民主选举：投出理性一票教案
1、第一，材料一和材料二的选举方式有什么异同？（1）相同点：①都采用了演讲和答辩等形式，都带有竞选的性质；②都采用无记名、直接选举的方式进行投票选举；③都属于差额选举。（2）不同点：①材料一是对村主任进行的正式选举，结果是直接产生村主任，材料二是对镇长候选人进行的选举，结果只是确定镇长候选人，镇长人选还有待进行正式选举；②材料一是全体村民都参加选举，材料二是各户派代表参加选举；③材料二比材料一更强调竞选的方式。第二，你还知道哪些选举方式？除了直接选举外，还有间接选举、等额选举、差额选举等。第三，你能对这几种选举方式的意义和效果，作出自己的评估吗？这是学习中要探究的问题，这里不一定能回答出来，等到学完本框内容后，可以得出比较明确的答案。第四，材料三给了你什么启示？这个问题不要求统一的答案，能讲出一两点即可。提示如下：（1）新中国成立后，选举制度经历半个多世纪的发展，正在逐步走向完善；
人教版高中政治必修1市场配置资源教案
教师点拨：这则材料说明，市场调节有其局限性，单纯的市场调节具有自发性、盲目性、滞后性等缺点。市场调节不是万能的。社会生活中有很多领域和产品不能用市场来调节，如国防、治安、消防等产品的供给问题，枪支弹药、麻醉品等都不能让市场来调节。市场调节具有自发性、盲目性、滞后性。自发性：由于市场调节是在价值规律自发作用下进行的，在利益驱动下会产生一些违反市场原则的行为，如制造、销售假冒伪劣商品，大量排放废水、废气破坏环境，窃取他人智力成果等等。盲目性：由于人们不可能完全掌握生产各方面信息及其变化趋势，致使决策带有一定的盲目性。如某种商品有利可图则一哄而上，反之则一哄而退，从而造成资源浪费和消费得不到充分满足。滞后性：由于市场价格的形成和传递有一个过程，一旦传递到生产经营者手中进行生产调整，就有一个时间差，致使市场调节带有滞后性，成为一种事后调节。
人教版高中政治必修1市场配置资源说课稿
（2）、市场调节存在固有的弊端：自发性：由于市场调节是在价值规律自发作用下进行的，在利益驱动下会产生一些违反市场原则的行为，如制造、销售假冒伪劣商品，大量排放废水、废气破坏环境，窃取他人智力成果等等。盲目性：由于人们不可能完全掌握生产各方面信息及其变化趋势，致使决策带有一定的盲目性。如某种商品有利可图则一哄而上，反之则一哄而退，从而造成资源浪费和消费得不到充分满足。滞后性：由于市场价格的形成和传递有一个过程，一旦传递到生产经营者手中进行生产调整，就有一个时间差，致使市场调节带有滞后性，成为一种事后调节。教师活动：请同学们想一想，市场的这些弊端和不足，会导致什么后果？（3）、危害教师总结：资源浪费，经济波动与混乱，分配不公两极分化等。设计意图：通过创设情景，加深对市场调节局限性的理解；要求学生结合生活实例探讨其弊端有助于加强对其产生原因和表现的记忆和理解。
人教版新课标高中物理必修1力学单位制教案2篇
一、教材分析在初中阶段，物理量单位的学习是学生较为困惑的问题之一。前面关于1N的规定给学生的印象总好像是有些随意。尤其是牛顿、帕斯卡、安培、伏特、焦耳、瓦特等单位的规定。使得学生感动物理太复杂。事实上，只有把单位制放在整个物理学框架中加以认识，并且知识有了一定的积累。经历了充分的学习过程后才能体会物理量单位的命名和使用规则。体会到其中对一些单位进行规定的合理性和方便特征。物理学单位中，有很少几个基本物理量，它们的单位就是基本单位。在进行了这种选定之后，其它物理量的单位就是根据它的定义式，有所选择的其他物理量的单位共同确定的。国际单位制的建立和使用，不仅方便了国际间的交流，也逐渐成为科学研究中计算和运用的一种规范约束。中学生应该注意学习，逐步习惯，在记录、表达和计算中规范使用。二、教学目标（一）知识与技能1．了解什么是单位制，知道力学中的三个基本单位；2．认识单位制在物理计算中的作用

人教版高中语文必修2《我有一个梦想》教案2篇
全班齐读第五段内容。请一位同学分析，接着让这位同学按他分析的读一遍。3、4两自然段的平缓之后，第5段作者的情感再次抬升。为了满足这种情感的张扬，作一口气连用了四个排比句式“现在是……时候”，一方面这是情感发泄的需要，另一方面这种排山倒海的语势也加强了内容的表达，极强地突出了现实为自由、平等而战的重要性。四、学会演讲我们刚才细读了课文，但读和讲是有区别的。所谓演讲，是一门语言艺术，它的主要形式是“讲”，即运用有声语言并追求言辞的表现力和声音的感染力；同时还要辅之以“演”，即运用面部表情、手势动作、身体姿态乃至一切可以理解的态势语言，使讲话“艺术化”起来，从而产生一种非凡的艺术魅力。那么，接下来就假设一下假如你是马丁·路德·金，你会怎样去讲这篇演讲辞。

This teaching period mainly deals with grammar “restrictive relative clauses.” To begin with, teachers should lead students to revise what they have learned about the relative pronouns and relative adverbs. And then, teachers move on to stress more special cases concerning this grammar, such as the “preposition+ relative pronouns which and whom” and cases where we can omit the relative pronouns. This period carries considerable significance to the cultivation of students’ writing competence and lays a solid foundation for the basic appreciation of language beauty. The teacher is expected to enable students to master this period thoroughly and consolidate the knowledge by doing some exercises. 1. Guide students to review the basic usages of relative pronouns and adverbs of attributive clauses.2. Lead students to learn to use some special cases concerning restrictive relative clauses flexibly.2. Enable students to use the basic phrases structures flexibly.3.
