人教版新课标高中物理必修1牛顿第三定律说课稿2篇
问：为什么会出现这样的情况，男女生之间的拉力存在着怎样的大小关系？进一步求证这两个力的大小关系经过共同讨论，得方案：把两个弹簧秤勾在一起，重现拔河比赛，分三种情况进行。（通过摄像头把弹簧秤的读数放大）两弹簧称勾在一起拉，处于静止不动时（即拔河比赛，双方处于僵持状态）两弹簧称勾在一起拉，并向一方运动（即比赛绳子被拉向一方时的状态）3、两弹簧称勾在一起拉，一方方向慢慢改变（两力方向始终在一条直线上）实验结论：两弹簧称的读数的变化总是相同的，大小相等，方向相反。得到牛顿第三定律：追问：既然两个力大小相等，那么拔河比赛为什么还存在胜负之分？讲清作用力与反作用力作用的受力物体不同，并和学生讨论如何做才会获胜。回应课前问题：“以卵击石”为什么鸡蛋碎？
人教版新课标高中物理必修1牛顿第二定律说课稿2篇
进一步引导学生思考利用数学知识可写成等式F=kma学生很自然就会思考比列系数K应该是多少？通过教师引导学生举例各国长度单位不同（如英国：英里、码、英尺、英寸；中国：市里、市丈、市尺、市寸、市分 ）导致交流不便。为了适应各国交流需要国际计量局规定了一套统一的单位，称为国际单位制 。取不同的单位制K是不同的，为了简洁方便，在选取了质量和加速度的国际单位（Kg, m/s2)时规定K=1。那么就有；F=ma为了纪念牛顿，就把能使1kg物体获得1m/s2加速度的力称做一牛顿，用符号N表示问题：实际物体受力往往不止一个，多个力情况应该怎么办呢？平行四边形法则进一步引导学生得出牛顿第二定律更一般的表达式: F合=ma思考.讨论我们用力提一个很重的箱子，却提不动它。这个力产生了加速度吗？要是产生了，箱子的运动状态却并没有改变。为什么？
人教版新课标高中物理必修1时间和位移说课稿2篇
研究一种物理现象，总是要先从现象的描述入手。机械运动作为自然界最简单和最基本的运动形态，它所描述的是物体空间位置随时间变化的情况。因此，本节学习描述质点做机械运动需要时刻、时间间隔和位移等概念。相当一部分高一学生在具体过程中难以区别时刻和时间间隔。另外，由于思维的定式，在第一次接触既要考虑大小又要考虑方向的问题时，会因不适应造成学习困难。所以，区别“路程与位移”“时刻和时间间隔”是教学的重难点所在。学习这些内容的过程与方法对学习速度和加速度可以起到奠定基础的作用。教学的对象是高一的学生，这一时期的学生处在好奇善问、创新意识强烈的青少年期。对于生活中出现的各种现象具有浓厚的兴趣。但他们的思维还停留在简单的代数运算阶段，对于矢量和矢量运算的理性认识几乎没有。且对生活中出现的时间、时刻、时间间隔等不能做出很好的区分，对时常提及的路程、距离等形成了模糊的前概念。
人教版新课标高中物理必修1质点参考系和坐标系说课稿2篇
一、说教材《质点 参考系和坐标系》是人教版普通高中物理必修一第一章第一课的内容。本节课主要介绍了质点、参考系、坐标系的基本概念。通过本节课的学习为进一步学习后续课程起到了铺垫的作用。根据上述教材的结构和内容分析，又考虑到高一年级学生的认知结构及其心理特征，我制定了以下三维教学目标：1、知识与技能：知道质点的概念及条件；知道参考系的概念及作用；掌握坐标系的简单应用。2、过程与方法：促进学生自主学习，让学生积极参与、乐于探究、勇于实验、勤于思考，培养学生的科学探究能力。3、情感态度与价值观：通过质点 参考系和坐标系的学习，使学生了解生活与物理的关系，让学生学会用科学的思维去看待事物。根据普通高中物理课程标准，并在吃透教材的基础上，我确定了以下教学重点和难点：教学重点：质点概念的建立。只有掌握了这一点才能更加准确的理解和掌握后续教材的相关内容。
人教版新课标高中物理必修1用牛顿运动定律解决问题（一）说课稿
六、教学程序设计（“一三五”模式）为了完成这节课的教学目标，我是这样安排的：第一环节： （约10分钟）根据对自主探究案的批阅情况，解决学生的遗留问题具体实施：投影学生的自主探究案，让学生交流讨论，教师点评。第二环节： （ 约30分钟）新课学习：在“课堂互动案”的导学提纲引领下，完成这节课的三维教学目标。具体实施：多媒体辅助教学、交流讨论。第三环节： （约5分钟）课堂小结和布置作业：为了体现课程改革的新理念——学生是学习的主人，我改变传统的教师总结为学生总结的模式，既强化了学生所学的知识，又培养了学生的归纳和概括能力。作业分为两部分：（1）书面作业p85，1、2、3、4。（2）完成“应用提升案”。七、板书设计由于多媒体在物理教学中仅是一种辅助手段，不能完全取代黑板，因此一节课的主要内容和学生的必要参与还需要借助黑板来帮助。我在这节课的板书设计中突出了主要内容，简洁明了。
人教版新课标高中物理必修1自由落体运动说课稿2篇
学生回答的方法多样，让各小组根据自己讨论出来的方法对自己实验出来的纸带进行数据处理，并求出加速度，并且将多条纸带都进行处理，同时提醒学生对纸带的选择。接着，我会用多媒体展示重物下落实验打出来的纸带，用表格列出一段纸带上各点的瞬时速度，准确画出v-t图像，求出加速度，将结果给予学生的结果作对比，确定出正确结论。最后让学生分析总结：自由落体运动是初速度为零的匀加速直线运动，而且，多条纸带算出来的加速度的数值都接近相等，即加速度在实验误差允许范围内是相等的。引出重力加速度，介绍概念、方向及大小。（强调“同一地点”，让学生阅读教材中一些地点的重力加速度，可以了解重力加速度的大小与纬度有关，纬度越大加速度越大）。学习了重力加速度后让学生根据之前学习的匀变速直线运动公式推导出自由落体的运动规律。设计意图：让学生在学习过程中的主体地位和自主观能动性得到充分发挥，取长补短，培养了学生的实验操作能力，又使学生对自由落体运动的性质有深刻的印象，从而解决了本节课第二个难点。

人教版高中语文必修3《寡人之于国也》说课稿2篇
（明确：“寡人之于国也，尽心焉耳矣”，但“寡人之民不加多，何也？”）②他认为自己对国家政务尽心尽力了，他有哪些具体做法？（明确：移民移粟）③第2—4节中孟子是怎样说明梁惠王移民移粟的措施与“邻国之政”并无本质区别的？（明确：孟子不直接回答“民不加多”的问题，而是用梁惠王熟悉的“战”设喻——设圈套，诱使对方在不知不觉中说出“不可，直不百步耳，是亦走也。”）④孟子认为怎样才能做到“王道之始”？要想“王道之成”还需采取哪些措施？（明确：“不违农时，谷不可胜食也。数罟不入氵夸池，鱼鳖不可胜食也。斧斤以时入山林，材木不可胜用也。谷与鱼鳖不可胜食，材木不可胜用五亩之宅，树之以桑，五十者可以衣帛矣。鸡豚狗彘之畜，无失其时，七十者可以食肉矣。百亩之田，勿夺其时，数口之家，可以无饥矣。谨库序之教，申之以孝涕之义，颁白者不负戴于道路矣。）这一小步的目的是想让学生通过这些问题的解答，可以进一步理清思路，掌握文的大概内容。
人教版高中语文必修3《老人与海》说课稿2篇
3、重要语句的理解“可是一个人并不是生来要给打败的，你尽可把它消灭掉，可就是打不败他。”解析：这是老人第一次回合之后的内心独白，也是此小说的核心精神，充分体现了老人桑地亚哥的生命理念。整句话可以分为两部分来理解，前句告诉我们，人生活在自然与社会当中，必不可少要面临一些坎坷、磨难，这些磨难、坎坷完全可以造成躯体的消灭、消亡，这是人生命的脆弱性。后句，面对挫折，只要保持一种乐观的精神，拥有一颗坚强的心灵，那么，人类执着奋斗的精神将永不磨灭。4、象征主义题目是《老人与海》，而表明上，小说是写一位老人及其在海上的经历，但实际上，老人的形象极具概括性，他已经超越了一个人的存在，而成为了人生的一种象征。老人桑地亚哥就是“硬汉子”的代表，大海则是生命旅途的象征，鲨鱼则是我们行走中的“强物”，厄运的象征。人的一生不可能一帆风顺，不经历风雨，怎能见彩虹，走在人生路途中，不可避免我们都要遇到挫折，被厄运所阻挠，只有经历与“鲨鱼”的较量，才能成为强者，唱出最美的歌。

“深入探究，把握主旨”这一步则是解决教学的重点难点，这里涉及到课文的深层意蕴，学生理解有难度，教师在通过问题引领学生探讨的基础上，还要适时启发、点拨，因为教学时间有限，让学生漫无边际的讨论，可能难以完成预定的教学任务，会使教学过程不完整。至于本文的写作特点的教学视时间而定，有时间可以让学生说一说，没有时间用小黑板出示一下，让学生了解就行，如果时间不够，甚至可以不讲。第三阶段是“延伸练习，巩固提高”。
