三、作出速度－时间图像（v－t图像）1、确定运动规律最好办法是作v－t图像，这样能更好地显现物体的运动规律。2、x y x1 x2 y2 y1 0讨论如何在本次实验中描点、连线。（以时间t为横轴，速度v为纵轴，建立坐标系，选择合适的标度，把刚才所填表格中的各点在速度－时间坐标系中描出。注意观察和思考你所描画的这些点的分布规律，你会发现这些点大致落在同一条直线上，所以不能用折线连接，而用一根直线连接，还要注意连线两侧的点数要大致相同。）3、若出现了个别明显偏离绝大部分点所在直线的点，该如何处理？（对于个别明显偏离绝大部分点所在直线的点，我们可以认为是测量误差过大、是测量中出现差错所致，将它视为无效点，但是在图像当中仍应该保留，因为我们要尊重实验事实，这毕竟是我们的第一手资料，是原始数据。）4、怎样根据所画的v－t图像求加速度？(从所画的图像中取两个点，找到它们的纵、横坐标（t1，v1）、（t2，v2），然后代入公式，求得加速度，也就是直线的斜率。在平面直角坐标系中，直线的斜率
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。

共享实验收集的信息，分享实验探究的结论，体验收获的乐趣。 小结拓展 这节课由大家感兴趣的球类运动和弹弓游戏，提出了功与速度变化关系的问题，利用倍增思想解决测量对物体做功的问题，使用我们熟悉的器材设计了探究方案，并进行实验探究，采用图像法进行数据处理，初步得出W∝V2的关系。在我们这节课探究以前，科学家就通过试验和理论的方法，已经总结出了功与速度变化的定量关系。人类社会也在社会生活和生产的各个领域予以利用。比如，古代的战争武器抛石器、大型弓弩，以及现代飞机弹射系统、还有机器人行走等等，希望同学在今后的学习中注意留心生活中的物理和社会中的物理。 领会总结。培养概括总结的能力，进一步巩固、感悟、提升实验探究中获得的思维能力及动手能力。感悟社会中的物理，认识物理学对科技进步以及文化和社会发展的影响。 列举学生知道的社会中做功使物体速度变化的例子，增强学生将物理知识应用于生活和生产的意识，培养学生的社会参与意识和对社会负责任的态度。
人教版高中历史必修3新文化运动与马克思主义的传播说课稿
一、说教材（一）教材分析本课所介绍的新文化运动，是继上一节所学的《西学东渐和维新变法思想》之后中国另一波影响巨大的思想解放潮流，旨在向西方学习、寻求强国御侮之道。在整个知识体系中，它既是资产阶级领导的旧民主主义革命的补课，又是无产阶级领导的新民主主义革命的序曲。它所带来的思想的空前解放，也就为马克思主义的传播创造了条件，为中共的成立奠定基础。这一课的学习能让学生清晰认识新文化运动和马克思主义在近代中国思想解放历程中的重要作用和巨大影响。与必修一和必修二政治经济史的结合也能让使学生强化历史联系。新课程标准对本课就做了明确的规定：1、概述新文化运动的主要内容，探讨其对近代中国思想解放的影响。2、简述马克思主义在中国传播的史实，认识马克思主义对中国历史发展的重大意义。根据课标要求，我制定了以下具体的三维目标。

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

人教版高中历史必修2古代的经济政策说课稿
3、清代的“闭关锁国”政策：（1）原因：①根本原因：自给自足的封建自然经济；②客观原因：西方殖民者向东方殖民扩张；③直接原因：对付东南沿海人民的抗清斗争（2）内容：严格限制对外贸易。但并不是禁绝海外贸易。康熙晚期，禁止商人前往南洋贸易；乾隆时只开广州一处通商，并设立政府特许的贸易机构广州“十三行”统一经营管理对外贸易。（3）后果：①闭关锁国政策妨碍了海外市场的开拓，抑制了资本的原始积累，从而阻碍了资本主义萌芽的发展。②闭关锁国政策隔绝了中国与外界的联系，从而阻断了中国学习西方的先进科学技术，阻碍了生产力发展，使中国落后于世界潮流。③“闭关锁国”政策在一定程度上也保护了国家的安全。教师可以设置问题：17-18世纪中国显露出哪些危机？

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，

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。]
人教版新课标高中物理必修1摩擦力说课稿2篇
本节课是人教社物理必修1第三章第三节的内容，编排在弹力之后。该节知识既是力学的基础，也是组成整个高中物理知识的一块“基石”，所以这节内容的教学如何引领学生自主积极地探究摩擦力产生的条件和影响因素，体验摩擦力特点规律的发生过程是本节课的重点，应高度重视本节教学过程；由于摩擦力问题的复杂性，且在具体问题中又表现出“动中有静，静中有动”，尤其静摩擦在许多情形下似乎又是“若有若无，方向不定”，因此，对于初学者也是有一定难度的。也正是由于教材内容的上述特点，本节课又易于激起学生的求知欲，易于培养学生的辩证观点，易于锤炼学生的物理素质。要充分用好该节教材内容，深入挖掘知识间的有机联系，对学生开展针对性的思维训练，进而提高学生应用物理知识解决实际问题的能力和创新思维能力。高中物理《课标》对该知识点的要求是，“通过实验认识滑动摩擦、静摩擦的规律，能用动摩擦因数计算摩擦力”。其中，对静摩擦力规律的认识应该包括最大静摩擦力。
