人教版高中数学选择性必修二变化率问题教学设计
导语在必修第一册中，我们研究了函数的单调性，并利用函数单调性等知识，定性的研究了一次函数、指数函数、对数函数增长速度的差异，知道“对数增长” 是越来越慢的，“指数爆炸” 比“直线上升” 快得多，进一步的能否精确定量的刻画变化速度的快慢呢，下面我们就来研究这个问题。新知探究问题1 高台跳水运动员的速度高台跳水运动中，运动员在运动过程中的重心相对于水面的高度h(单位：m)与起跳后的时间t(单位：s)存在函数关系h(t)＝－4.9t2＋4.8t＋11.如何描述用运动员从起跳到入水的过程中运动的快慢程度呢？直觉告诉我们，运动员从起跳到入水的过程中，在上升阶段运动的越来越慢，在下降阶段运动的越来越快，我们可以把整个运动时间段分成许多小段，用运动员在每段时间内的平均速度v ?近似的描述它的运动状态。
人教版高中政治必修3建设学习型社会说课稿
解析：材料是讲学习型社会所产生的影响，A项观点错误，在当前和今后相当长的时间里，学校教育仍然是人们获得知识的最重要的途径。B项观点错误，终身学习只是成就人生目的的手段、途径，而不是目的本身。D项说法错误，当前我国社会的中心工作是经济建设。二、问答题5.材料一：日本是公认的漫画大国，日本的动漫产业产值每年230万亿日元，成为日本的第二大支柱产业。在日本，漫画比电影、小说有时甚至比电视或音乐更受欢迎。日本漫画的热潮还席卷了世界：日本每年出口到美国的卡通片价值就达5 000亿日元，是日本对美国钢铁出口金额的4倍；漫画中的人物被迅速复制成电子游戏、卡通片及真人演出的节目。原来只是闲暇时候消遣的漫画，正飞速渗透到人们的生活中。值得警惕的是，除了催人奋进的精华之外，日本漫画中也存在暴力、色情、扭曲历史等诸多糟粕，对缺乏辨别能力的青少年产生了许多不良影响，更引发了一系列深刻的社会问题。
人教版高中语文必修1《新词新语与流行文化》说课稿
当代社会生活的变化比以往任何时代都要快。语言尤其是词汇记录了这些发展变化，因而也涌现了大量的新词新语。据统计，近几年每年大约要出现１０００个左右的新词新语，而字典、词典的多次修订、增补就反映了这种情况。但相对来说，也有一些流行语又逐渐受到冷遇，甚至退隐。为了更好的对新词新语与流行文化作一番检视与探究，那让我们考察一下它们是怎么产生的吧？老师先给同学们列举四种途径：大屏幕３。同学们能再举出以上途径的一些例子吗？老师列举（４）其实不只这些，那还有哪些途径呢？找同学说并举例。说的非常好，请同学们看老师的例子，总结（５）。从新词新语的产生途径可以看出，这些鲜活得像画一样的新词就是这个时代跳动的血小板，它涉及当代社会的重大事件、现象与时弊，以及人们日常生活的各个层面如人生意义、生活方式、爱情、友情、就业、消费、时尚等，时代性强，传播面广，反映着当代社会时局与人们文化心态的变化。
区政协主席在 “疏整促专项行动”工作座谈会上的讲话范文
第一，要提高政治意识和政治站位 “疏整促专项行动”工作不是传统整治工作的延续，而是从建设一个什么样的*、怎样建设*，这样的政治高度和*新的定义角度开展。围绕着“四个中心”怎样建设*、怎样建设国际一流的和谐宜居之都，所以“疏整促专项行动”工作要从这个高度开展。看*要从*的高度、政治的高度看，要提高“四个意识”，特别是要提高政治站位、政治意识，要用*的标准、*的要求来衡量和看待我们的工作，不符合*功能的都需要疏解。目前不主动作为，以后被逼着作为时，所有发展机遇都已经失去了。只有疏解、腾退了空间，才可能承接更高端的东西。如果没有这个政治意识和政治站位，把空间腾退出来，即使给了我们区这种规划和定位，也没有空间来实现它。我们的发展空间只能从拆违中拿，从腾退中取。在这点上，大家在思想上一定要真正想明白这个道理，不疏解就没有出路。要认识到这是一项政治任务，也关系到未来我们要建设一个什么样的*。 第二，要做好“疏整促专项行动”这件大事 疏解的目的是为了提升，我们提升的是人居生产生活环境，提升的是城市品质，提升的是群众获得感，所以要做好规划引领。要按照“四个中心”的定位和*的标准，高水平、高层次的超前规划、超前设计。一是要符合生态特性，*是*的西南生态屏障，也是*的一个重要定位，未来*建设要突出生态特色、科技特色、文化特色，这是*未来发展的方向。二是要保障民生，这也是委员们多次提到的问题，过去小散乱污不环保、不高端，但是方便。现在整治后，环境、产业、品质都提升了，但是不方便了。在提升的同时便民服务设施要提早规划好、建设好。还要尽量为群众多留绿色空间，我们一切工作的最终目的都是让*老百姓过上更好的生活。三是要加强社会监督、舆论监督、群众监督。“疏整促专项行动”工作应该是全员参与的工作，不能政府干，群众看，要让老百姓参与进来，利用好新媒体，加大宣传，建立举报监督奖励机制，让更多的老百姓参与进来，真正发挥群众的力量，打一场拆违的人民战争，建立一种监督执法的长效机制。

人教版高中英语必修4A taste of English Humor说课稿3篇
Then I would ask them to think of a funny English or Chinese and tell it to partners. While telling stories, they can use expressions and some acting to help make the story funny. 5 minutes would be given to do this.Those stories they told there will be the material for their writing. Soletting them tell it at first is helpful. And they can make a difference between telling a funny story and writing it down. Generally speaking, it is difficult forstudents to write well because they don’t know what to write and how to write. Asking them to tell their own stories at first can help them come up with what to write.After their telling, I would invite someone to share his/her story with all of us and I would write it down on the blackboard.This example story would be used as a sample to illustrate the format of funny story. Different from a story from teacher or textbook, a story from students can obviously become a interesting material to draw students’ attention.Then I would ask the whole class to put this story into several parts. It might be a little bit difficult for them. So I would ask them to find out whether all the sentences are necessary. After delete some sentences, there are 6 sentences left behind. Then they can easily put them into three parts. After interaction with students, I would teach them the right terms for each part and conclude the format of funny story.This step is the key and difficult point in my lesson. So I mainly usetask-based teaching method in this part and the task for students was divided into several stages. With the separated difficult level, students can find there are usually three parts in writing. They can also learn to write without the unnecessary parts in the process of analyzing. And then I wouldn’t rush to tell them the right terms to them directly. Instead, I would ask them to name them by their own. A confused mind is better for acquiring knowledge.While-writing:Then I would give students 7 minutes to write down this story, without other requirements.With all the preparations in pre-writing, students’ difficulties were cleared. So it would be much easier for them to write down the story within 7 minutes. There are no other requirements because students’ first writing is actually a drafting. It would be revise and edit several times later. Writing, as a skill

人教版新课标高中物理必修1弹力说课稿3篇
基于以上分析，为使本堂课围绕重点、突破难点，同时让学生在课堂教学中能力得到提高，我设计如下教学过程。（一）创设情景认识形变由同学们已有的形变知识入手，引入新课。教师演示：①弹簧的压缩形变；②弹簧的拉伸形变③视频播放：竹竿形变、钢丝的扭转形变。得出形变的概念及各类形变。[设计意图：我从生活情景中引入新课，是为了激发学生的好奇心，为学生学习重点和难点内容作铺垫。]设问：摩天大楼在风的吹拂下会不会摆动，发生形变吗？演示微小形变放大实验：由于这种形变不容易观察，会使学生产生疑问：到底有没有发生形变？解决的办法是微小形变的演示实验。为什么光点会往下移？让学生带着问题思考后得出结论：是由于桌面发生了形变，但是形变不明显。为后面解决压力和支持力都是弹力做好铺垫。[设计意图：使学生知道“放大”是一种科学探究的方法。]

通过这个示例呢，我们可以得到解决向心力问题的一般的步骤，确定对象，找出轨迹，找出圆心，然后进行受力分析，让同学们参考这样的步骤，逐步的解决圆周运动的问题，对于变速圆周运动，我通过链球运动进行引入，这里是一个链球运动的视频，在同学们观看视频之前，我给同学们提出问题，链球收到绳子的拉力，做的是匀速圆周运动吗？ 然后再课堂上我们再做一个小实验， 我们可以通过改变拉线的方式来调节小球的速度大小吗？ 那么对小球，做加速圆周运动，进行受力分析，我们可以看到，小球做加速运动时，他所受到的力，并不是严格通过轨迹的圆心，在进行分析的时候，特别强调，小桶所受力的切线方向分力，和法线方向分力，切线方向分力，改变小球运动速度大小，法线方向分力，改变了小球运动的方向，法线方向的分力，在这里就是向心力，产生了向心加速度，通过这样一个例子进行分析，同学们是比较容易理解的，
国旗下讲话稿3篇
迈着轻盈的步伐，沐浴3月的阳光，在这播种的的季节里，我们又迎来了播种希望的新学年。也许，昨天的你拥有许多辉煌，但那已成为了一段甜蜜的回忆;也许，过去的你遇到无数挫折，但那已是几滴消失了的苦涩泪痕。让我们忘记从前的成功与失败，只把收获的宝贵经验与教训铭刻在心。正如面对一个盛着半杯水的杯子，悲观的人永远说它是半空的，而乐观的人则会说它是半满的。不同的心态决定了我们对待生活，对待学习的态度。新学年，换一种心态，学习生活将是一方艳阳天。业精于勤荒于嬉。同学们，我们要想取得好成绩，勤奋是必不可少的，也是最为重要的。鲁迅先生曾说过：“哪里有天才?我只是把别人喝咖啡的工夫都用在工作上了。”孔子晚年看《周易》时，穿书简的皮绳不知磨断了多少次!唐代诗人白居易幼年好学，勤奋不懈，年仅16岁就写出了“野火烧不尽，春风吹又生“的千古绝句。勤奋不一定会成功，但成功肯定以勤奋为基础。琅琅书声是我们献给太阳的礼赞，晶莹露珠是我们迎接日出的问候。不断追求心中的梦想，不断振奋克服困难的勇气和决心，经受风雨，勇往直前，只有这样，我们才能够响亮地回答：我们没有虚度时光。
人教版新课标小学数学四年级上册商的变化规律说课稿2篇
第三个规律，商不变的规律。这是本课的重点内容。有了两次的探究经验，这一规律的学习与理解，可以完全放手让学生自主进行。猜想如果商不变，被除数、除数会发生什么变化呢？学生根据已有的经验，可能会有不同猜想，我要求学生带着问题通过计算、观察、比较、主动探讨总结出：被除数和除数同时扩大（或缩小）相同的倍数（0除外）商不变。利用合作学习，通过动脑动口动手，既提高学生解决问题的学习能力，又培养了合作学习的意识和习惯。给学生提供展示研究成果的机会，体验成功。需要教师提醒的是“有没有被除数和除数同时乘或除以不相同的数，商也不变的？”学生举反例加以说明并指出“相同的倍数不包括0”。设计这个环节，也有意让学生去验证商不变性质。学生在表述时，对于逻辑的严密性和语言的完整性需要老师及时指导，在突出重点的同时培养学生的语言表达能力。整个环节在验证的基础上，步步深化商的变化规律，为学生应用新知做好铺垫。

三、总结规律、形成概念通过学生积极讨论，充分调动了学生的积极参与学习，既发挥了学生学习的主动性，又培养了学生的发散性思维，引导学生总结出：有的分数可以化成有限小数，有的分数不可以化成有限小数，请同学们再看一看什么样的分数可以化成有限小数？什么样的分数不可以化成有限小数？启发学生从分母的最小公倍数着手。 最后总结出：一个最简分数，如果分母中只含有素因数2和5，再无其它素因数，那么这个分数就可以化成有限小数，否则就不能化成有限小数。 例题2，请把下列小数化成分数，说说你是怎样把小数化成分数的？ 0.06，0.4，1.8，2.45，1.465, 归纳：（学生为主，教师点拨）1、原来有几位小数，就在1后面写几个零作分母。原来的小数去掉小数点作分子。2、小数化成分数后，能约分的要约分。常用的因数是2和5。 对于小数如何化成分数的题目，课前了解到学生在小学时已学过把小数如何化成分数的方法，因而以学生练习为主，加以操练并巩固，有错误的及时纠正。
