人教版新课标高中物理必修1牛顿第二定律教案2篇
1．这节课以实验为依据，采用控制变量的方法进行研究。这一方法今后在电学、热学的研究中还要用到。我们根据已掌握的知识设计实验、探索规律是物体研究的重要方法。2．定义力的单位“牛顿”使得k=1，得到牛顿第二定律的简单形式F=ma。使用简捷的数学语言表达物理规律是物理学的特征之一，但应知道它所对应的文字内容和意义。3．牛顿第二定律概括了运动和力的关系。物体所受合外力恒定，其加速度恒定；合外力为零，加速度为零。即合外力决定了加速度，而加速度影响着物体的运动情况。因此，牛顿第二定律是把前两章力和物体的运动构成一个整体，其中的纽带就是加速度。四、评价方案及说明1、对科学知识与技能的评价要注重科学内容的理解与应用，而不是单纯记忆。技能的评价目标包括观察技能、实验技能等方面。对科学的技能的评价要尽量融合在科学探究过程的情景中。对科学知识的评价主要从两方面，一是根据学生诊断性练习；二是通过学生作业反映学生掌握情况。
中班科学《丰富多彩的塑料品》说课稿
随着科学技术的断进步和发展，丰富多彩的塑料制品在人们的生活中随外可见，塑料制品的广泛应用给人类带来的是什么？学习这一课让幼儿明白，塑料制品它一方面给人们的生活带来了许多便利，同时也造成了“白色污染”的危害。幼儿在生活中几乎每天都能接触到各种塑料制品的实物，因此，这一课题幼儿容易接受和掌握，同时，这一课题中的教具，具体、直观、丰富多样，大量生动的实物教具易于刺激幼儿感官，激发幼儿学习兴趣和近不急待的探索欲望。有关“白色污染”的总是对幼儿来说有些抽象，针对这一问题，我在课前组织幼儿清理园内的塑料垃圾，再观看有关“白色污染”的图片和纪录片，幼儿会很透彻地理解“白色污染”。
人教版高中语文必修1《烛之武退秦师》说课稿2篇
4、本文的重点是说辞，虽仅百余字，却委婉曲折，步步进逼，层层深入，表现出高超的劝说艺术、游说技巧。让学生细细品味并概括说辞中包含几层意思。第一层（“秦、晋围郑，郑既知亡矣”），分析形势，以退为进，博得好感。第二层（“若亡郑而有益于君”至“君之薄也”），亡郑陪邻，动摇联盟。第三层（“若舍郑以为东道主”至“君亦无所害”），存郑有益，利益引诱。第四层（“且君尝为晋君赐矣”至“唯君图之”），追溯历史，深入离间。可见烛之武面对大国的君主，巧舌如簧，不卑不亢，从容辞令，既不刺激对方也不失本国尊严，语言的分寸掌握得恰到好处。表现出烛之武机智善辩的外交才能。5、面对风云突变的局势，晋侯没有感情用事，而表现了清醒的头脑和理智的判断。这种隐忍不发、随机应变的胸怀和谋略，正是晋文公终成霸业的根本原因。设计意图：本环节的重点是全面把握烛之武这一人物性格特征，以及退秦师过程中体现出的非凡的胆识以及高超的谋略和语言艺术。
大班语言《秋天多么好》说课稿
我今天说课的内容是大班语言：谈话；秋天多么好。谈话活动是培养幼儿学习在一定范围内运用语言与他人进行交流的语言教育活动类型。在这个教材中要求教师引导幼儿围绕秋天的天气、景色、动植物的变化、人们在大自然界中的活动等，把自身观察到的、感受到的用语言表达出来。这就需要幼儿要有丰富的有关知识经验，因此本次活动的知识点是：秋天的气候和花草树木的变化、几种农作物的丰收和小动物的活动、人们的服装变化等主要特征。为此，在课前采用多种形式如家长带幼儿到郊外去秋游，日常生活中教师引导幼儿观察等。让幼儿观察到、感受到大自然的变化，丰富有关的知识经验。另外再启发幼儿一同上网或去图书馆查阅资料，探索大自然的奥妙，搜集具有秋天特征的图片等。引起幼儿进行谈话的兴趣和积极性。这一知识点在整个知识结构中占基础地位，也是整个教学活动能否顺利开展的关键所在。纲要所提出的要让幼儿乐意与人交谈，讲话礼貌；能注意倾听他人讲话，能清楚的说出自身想说的事。为此制订三了教学目标：1、激发幼儿热爱生活、热爱大自然的美好情感。2、引导幼儿运用已有的知识经验围绕主题大胆回答与交流，发展口语表达能力，培养幼儿注意倾听的好习惯。3、丰富词汇：秋高气爽、凋谢。
大班综合《多变的围巾》说课稿
冬天里，围巾是每天都能用到的，每个小朋友都有围巾，但是一般孩子都是家长代劳，所以确立目标1：尝试打围巾结；另外，围巾除了保暖外，还有打扮自己的作用，为了发挥幼儿的想象力和创造力，所以确立目标2：乐于用多种方法系围巾，打扮自己；由于幼儿尝试动手打围巾结，所以必须人手一条围巾，四十多条围巾，很好的教育机会，所以确立目标3：观察各种各样的围巾，这也是对幼儿观察能力的一种培养。本次活动是一个综合活动，它涉及到了艺术领域、语言领域、科学领域三个方面，对于我们这个地区来讲，围巾在冬季比较常见，但是围巾也包括冬季的保暖围巾和秋冬的防风沙、打扮自己的纱巾，幼儿自备了各种各样的围巾进行系围巾和观察围巾，教材的选择适合大班幼儿的水平及特点。基于我班幼儿喜欢动手操作，所以这一活动很适合我班的幼儿。
春季学期第二周国旗下讲话稿：争做文明学生，共筑美好校园
老师们，同学们，大家早上好！今天我国旗下讲话的主题是：争做文明学生，共筑美好校园。大家知道做什么事情不简单、做什么事情不平凡吗？把每一件简单的事情做好，就是不简单；把每一件平凡的事情做好，就是不平凡。我的一个好朋友，每次在食堂吃完饭，都会一边把盘子递给收餐具的阿姨，一边礼貌地对她说声“谢谢”。收餐具的阿姨通常忙得顾不上回答——她们正以最快的速度整理着几只手同时甩在桌上的餐盘。不过也有时候，阿姨会冲我们笑笑，或者开心地说“不用谢”，然后继续麻利地工作。我不知道这一句简单的“谢谢”能有多大的作用，不过我想，至少这个阿姨的一天可以因此多一丝愉快，我们的校园里可以多一点文明的正能量。
第二学期第2周国旗下讲话稿：学雷锋精神，做友善之人
老师们、同学们：大家好！今天我国旗下讲话的题目是《学雷锋精神，做友善之人》。春意融融的阳春三月即将到来，神州大地的每一个角落，尤其是学校都将再次掀起一股“学雷锋”的春风，这股永吹不停的“春风”是人们对往年学雷锋活动的总结和后续，又是雷锋精神的深化和发扬。雷锋，这个光辉的名字，犹如一颗明亮的星，为亿万人所景仰、所熟知。因为它成为一种不朽的象征——象征着我们民族勤劳、简朴、关心他人，克已奉公的优良传统；同时它成为一种永恒的启示——启示着我们一代又一代青少年奋发向上、不竭努力，为实现人类美好的理想而奉献出每一分光和热。毛主席说过“一个人做一件好事不难，要做一辈子好事，却很难很难”雷锋叔叔就是一个这样的人。他心中时刻装着祖国，装着他人，雷锋叔叔说过“人的生命是有限的，我要把有限的生命投入到无限的为人民服务当中去”他用年轻的生命实践了自己的诺言。
XX-XX第二学期第六周国旗下讲话稿：珍惜粮食，做勤勉节俭的xx学子
尊敬的老师、领导，亲爱的同学们：大家早上好!今天我发言的题目是“珍惜粮食，做勤勉节俭的xx学子”。关于这个题目，我的发言有三点。第一，珍惜粮食，从我做起。“谁知盘中餐，粒粒皆辛苦”告诉了我们粮食来之不易的道理。学校领导很早就倡导全校师生开展“光盘行动”：盘里不剩菜，碗里不剩米。无论对于老师还是学生，这个标准都不能打任何折扣。可是现在，我们仍然可以看到有同学浪费食物的现象，吃不完的米饭随意倒掉，而且很“大方”、不犹豫。试想，我们学校近300名师生就餐，每人每顿少浪费一粒米，这数额积累下来，至少可以让一个饱受饥饿之苦的人解决温饱问题，这样下来，又可以节约资源求得学校更好的发展，何乐而不为呢？都说温饱不忘饥寒，增产不忘节约。我们处在衣食无忧的好时代，学校也处在稳步发展的关键时期，我们要从自身做起，珍惜粮食，杜绝浪费。

新人教版高中英语必修3Unit 4 Space Exploration-Listening&Speaking＆Talking教学设计二
The themes of this part are “Talk about how to become an astronaut” and “Talk about life in space”. As Neil Armstrong said “Mystery creates wonder and wonder is the basis of man’s desire to understand. Space is difficult for human to reach, therefore, humans are full of wonders about it. However, if wanting to achieve the dream of reaching the Moon, some of our human should work hard to be an astronaut at first. Part A(Talk about how to become an astronaut) is a radio interview in a radio studio, where the host asked the Chinese astronauts about his story how to become an astronaut. Yang Liwei told his dreamed to be an astronaut since childhood. Then he worked hard to get into college at 22. The next 10 years, he gradually became an experienced pilot. At the same time, to be an astronaut, he had to study hard English, science and astronomy and trained hard to keep in good physical and mental health and to practise using space equipment. Part B (Talk about life in space) is also an interview with the astronaut Brown, who is back on the earth. The host Max asked about his space life, such as his emotion about going back the earth, the eating, shower, brushing, hobbies and his work. Part A and Part B are interviews. So expressing curiosity about the guests’ past life is a communicative skill, which students should be guided to learn.1. Students can get detailed information about how Yang Liwei became an astronaut and Max’s space life.2. Students learn to proper listening strategy to get detailed information---listening for numbers and taking notes.3. Students can learn related sentences or phrases to express their curiosity like “ I wish to know...” “I’d love to know...”4. Students can learn more about the space and astronauts, even be interested in working hard to be an astronaut

⑦在我看来, 探索太空是值得的。As far as I am concerned, it is worthwhile to explore the space.Step 10 Writing---draftRecently, students in our class have had heated a discussion on whether space is worth exploring. Students hold different ideas about it.30% of us think space exploration is not worthwhile. They think space is too far away from us and our daily life and is a waste of money. And the money spent on space exploration can be used to solve the earth’s problems such as starvation and pollution.On the other hand，70% think space is worth exploring because we have benefited a lot from it，such as using satellites for communication and weather forecast. What’s more，with further space research，we may solve the population problem by moving to other planets one day. Also，space research will enable us to find new sources to solve the problem of energy shortages on the earth.As far as I am concerned, it is worthwhile to explore the space. Not only can it promote the development of society but also enrich our life. Step 11 Pair workExchange drafts with a partner.

小班语言《亲亲长颈鹿》说课稿
《亲亲长颈鹿》这个故事选自小班下学期，《有趣的动物》这一主题中。该故事选用了小朋友生活中比较熟悉并喜欢的小兔子和长颈鹿为角色，讲述了一个长颈鹿阿姨助人为乐的故事，特别是小兔子们亲亲长颈鹿阿姨这个情节既让人觉得有趣又很符合小班小朋友的年龄特点，生活中我们也会经常看到自己班的小朋友亲亲老师的小手或者脸蛋来表示他对老师的喜爱之情。又考虑到现在的小朋友大多数都是独生子女，特别是小班幼儿年龄小，个个都“以自我为中心”，缺乏友爱互助的品质，所以我觉得这个故事既符合小班幼儿年龄特点，又符合孩子的现实需要，因此，我选择了这个故事，并将它与语言和社会两个领域相结合。
