《一次函数与二元一次方程组》说课稿
一、 说教材、目标这部分内容建立在学生对一元一次方程、二元一次方程组和一元一次不等式等以一次（线性）运算为基础的数学模型的已有认识上，从变化和对应的角度对一次运算进行更深入的讨论。从函数的角度对一次方程（组）、不等式重新进行了分析，这种再认识不是对原有知识的简单回顾复习，而是站在更高起点上的动态分析，是用一次函数将上述三个不同的数学对象起来认识，发挥函数对相关内容的统领作用。通过这部分内容的学习，不仅可以加深学生对方程（组）、不等式等数学对象的理解，而且可以增强对相关知识的内在联系的认识，加强知识间横向与纵向的融会贯通，提高灵活分析和解决问题的能力。本节课是在前两节课已经学完了一次函数与一元一次方程、一元一次不等式的联系之后，对一次函数与二元一次方程（组）关系的探索，是对一次函数及其相关内容更深入、更全面的学习，也是对这部分内容的一个提升和总结。
国旗下的讲话:学会生活 学会学习
国旗下的讲话:学会生活学会学习老师们、同学们：时值深秋，从传统节气上讲，我们现在已步入寒露，古语说：“露气寒冷，将凝结也。”首先希望大家注意保暖。即将到来的冬季是我们中学生最为宝贵的学期，有很多的挑战、考验以及收获和惊喜在等待着大家。在此，我想问同学们三个问题。第一个问题：这个学期，你制定了奋斗目标吗？实现梦想的历程是需要规划的，当我们把它分解为一个一个阶段，每个阶段都有一个明确的目标时，梦想就显得不那么遥远了。当这些目标逐一实现——就像游戏打完了通关，你就成为了梦想中的最好的自己。目标不要定的过高也不要让自己太轻松。目标应该是具体、明确、清晰、可见的，你可以清楚自己是怎样越来越接近目标的，成就感和自信心就会伴随着你。下面这个故事将会告诉你目标以及目标的确定性与清晰度是如何的重要。弗洛伦丝·查德威——第一个往返游过英吉利海峡的女子。她在卡特里那海峡冰冷的海水里坚持游了将近16个小时之后，她想上船了。母亲在护卫船上鼓励她再坚持一会儿：“你已经离岸边很近了——你能游完全程的！”但弗洛伦丝看不到，放眼望去，只有浓雾。她被人拉上了护卫船。很快，她发现，她其实离岸边只有不到半英里了！不是疲劳，也不是冰冷的海水打败了她，而是大雾使她看不到自己的目的地。可见，目标是努力的方向，是前进的动力，是精神的支柱，是指路的明灯。有一个清晰和确定目标的新学期生活一定是充实和富有意义的。

小班语言《母鸡太太和两个蛋》说课稿
唤起幼儿对母亲爱的情感，使幼儿感受到亲情是多么美好<<母鸡太太和两个蛋>>幼儿园语言教案的内容，是一篇优秀的文学作品，故事中讲述了母鸡太太为了孩子出生辛苦孵蛋，及小鸡知道妈妈的辛苦在蛋壳谈论怎样回报妈妈，唤起幼儿对母亲爱的情感，使幼儿感受到亲情是多么美好这个故事，语言精练优美，抓住妈妈爱孩子，孩子爱妈妈这一关在键点，根据《纲要》精神和孩子已有的能力实际、知识水平及教材要求，我确定了本课的教学目标、重点、难点。1、情感目标：在感知和理解故事的过程中，体验妈妈爱孩子，孩子爱妈妈的情感2、能力目标：要求幼儿能简单地表演故事中的对话语言.3、知识目标：鼓励幼儿大胆地运用已有生活经验理解和回答问题.
幼儿园中班说课稿：我爱大树和小花
二、说活动目标 活动目标是教学活动的起点和归宿，对活动起着引导性的作用。根据《新纲要》在科学领域中提出：在幼儿生活经验的基础上，帮助幼儿了解自然、环境与人类生活的关系。从身边的小事入手，培养初步的环保意识和行为。根据这一目标和要求，结合中班幼儿年龄特点制定了认知、技能、情感三方面的教学目标。1、目标一：欣赏图片阅读教材，理解图片内容知道花草树木对人类的作用。2、目标二：欣赏图片并根据生活经验，说出几种花草树木的名称和作用及其保护方法。3、目标三：了解花草树木与人类的依存关系，萌发幼儿保护花草树木及环境的意识，产生爱树爱花的情感。 （目标定位：通过欣赏图片阅读教材来了解花草树木对人类的作用，了解花草树木是怎样为人类服务的，萌发幼儿爱护花草树木的情感）三、说教法与学法 《新纲要》中强调幼儿是中心，教育活动应该以幼儿的需要，兴趣，尤其是幼儿的经验来进行，学决定教。在活动中我和幼儿的角色都是教学活动的主人翁，主要是以幼儿为主。让幼儿在教学活动中享受探究问题及解决问题的快乐。所以在教学活动中我采用了“图片观察法”运用直观、形象的图片进行欣赏，引导幼儿理解图片内容及其意思。“游戏法”通过游戏让幼儿亲身体验怎样爱护花草树木让幼儿更深一层的了解爱护花草树木需要做的事情，在游戏中让幼儿学会爱护花草树木的深刻内涵。四、说活动准备 活动中准备：挂图四幅、幼儿用书第37-38页、五幅环保画（例如：树木被破坏、花朵被摘……）、制作花朵大树头饰幼儿人数各一半
幼儿园说课稿 我爱大树和小花
我今天说课的内容是选自幼儿园建构式课程中班下册科学教育活动《我爱大树和小花》。《新纲要》科学领域目标中明确提出了：培养幼儿爱护动植物，关心周围环境，亲近大自然，珍惜自然资源，有初步的环保意识。在我们生活的周围有各种各样的树和花，对于孩子来说既熟悉又陌生，每每在户外活动时孩子总会不经意地去看看、摸摸，有时还会说一句，如：这颗树好大哦，这朵花好漂亮哦，有时候还会进行追问，如：这颗叫什么树，这叫什么花……然而随着社会的进步人类慢慢淡化了对身边花草树木的爱护，甚至亲手破坏身边的环境，如：乱砍树木，乱摘花朵……结合中班建构式课程中的主题教学《大树和小花》的内容，我设计了符合中班幼儿年龄特点的教学活动《我爱大树和小花》，引导幼儿要保护身边的花草树木，清楚花草树木与人类的关系以及对人类的作用。通过挂图与教材的阅读理解保护花草树木的重要性，从而萌发幼儿爱护花草树木的情感。
幼儿园中班数学教案：有趣的数数
2、发展幼儿思维的准确性、灵活性，激发幼儿参与数学活动的兴趣。 活动准备 1、连线纸、水彩笔人手一份 2、鸡蛋、鸭蛋、鹅蛋、鸟蛋图片若干 3、摆放成封闭式的平面鸡蛋、鸭蛋、鹅蛋、鸟蛋若干张 4、数字卡片 活动过程 一、引起幼儿兴趣、交代主题，活动导入。 1、游戏《连线找客人》 “今天我们这里来了四位神秘的客人，把卡片上的点子按数字从小到大的连起来，你就可以知道了。” 2、幼儿连线，教师将幼儿作品贴在黑板上。 今天来的客人是谁？（一起说一说） 小动物们说：小朋友，你们知道谁是我的妈妈吗？请你们帮帮忙，把我们的妈妈找出来吧！ 出示相应的动物妈妈图片。
大班科学教案：旋转的彩球（科学）
2．幼儿操作材料：长铜丝、短铜丝若干，粗细不同的圆铅笔、吸管、小棒等若干，圆形彩纸片若干，浆糊、抹布，橡皮泥，别针。活动内容：1．演示彩球玩具，引起幼儿兴趣。⑴教师演示玩具，请幼儿观察现象。⑵介绍玩具的构造。①教师：这个玩具有几个部分组成的呢？②示范弹簧的制作方法。2．请幼儿来制作玩具。⑴幼儿尝试自己制作旋转彩球玩具，教师巡回指导。⑵幼儿玩一玩自己制作的玩具。⑶交流制作经验。教师：①你是怎样做旋转彩球的？你的彩球能滑下来吗？怎样滑下来的？②师生共同小结。3．讨论：为什么彩球下滑转动快慢不一样。⑴比一比：谁的小球转得快？⑵想一想：为什么彩球转的快慢不一样呢？弹簧粗的转得快还是弹簧细的转得快？⑶小结：原来有的小朋友他绕的弹簧比较细，所以彩球转的快；有的小朋友绕的弹簧粗，所以彩球转的慢些。4．怎样使彩球转得快些。⑴猜一猜：不改变弹簧的粗细能不能让彩球转得快些？⑵幼儿尝试，教师做必要的提醒和指导。⑶小结：活动延伸：1．将材料投放在科学角，供幼儿平时操作。提供橡皮泥，鼓励幼儿尝试将纸球换成橡皮泥，改变两边橡皮泥的重量，观察其下滑速度的变化。2．在日常生活中引导幼儿观察重力与速度变化的现象。活动建议：1．长短铜丝应分别为两种规格，利于幼儿对比。
人教版高中语文必修1《再别康桥》说课稿2篇
一、教材分析1、教学对象分析《再别康桥》的教学对象是高一学生，高一学生往往对那种纯粹的、原始的、本真的情感体会较为肤浅，《再别康桥》是新月派诗人徐志摩的传世之作，有极高美学价值，它所抒发的离愁别绪是人类共同的情感经历，通过诵读容易将学生带人诗境，唤醒他们沉寂的真情，从而引起强烈的共鸣。 2、教材地位及作用 高中语文第一册第一单元为诗歌单元，本单元收录了中国现当代的一些优秀诗篇。《再别康桥》安排在本单元的第二课，属于必读课。虽然本诗向来众说纷纭，但其艺术之美人所共知，培养学生高尚的审美情趣和良好的审美创造力是语文学科的任务，因此，从语言赏析入手，从情感体验切入，就可以让学生通过学习本课体会现代诗歌的特点，多方面感受体悟诗歌的情感，受到美的熏陶。
人教版高中语文必修2《囚绿记》说课稿2篇
“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”。
人教版高中语文必修1《论语》说课稿
三、文本中的句子解决完毕，大家对文本内容的理解更加深入了。请速度文本，思考：《论语》具体涉及了哪些方面的内容，体现了孔子什么观点？明确：主要有治学、从政、修身养性和交友治道等方面，体现了孔子“克己复礼”的思想。四、 教师引导学生讨论： 如何评价孔子的言行和观点？从古至今人们对孔子有哪些评价？明确：1、春秋战国时代， 孔子门人及其后学者均推尊孔子。门人中以子贡为代表，他对孔子赞美备至，奉如天人，把孔子比拟为高天、日月、木铎，凡人是永远不可企及的，认为孔子是天生的圣人，“仰之弥高，钻之弥坚”。亚圣孟子认为孔子所行的“圣人之道”是遍及自然界和社会的至高准则。然而当时民间一般看法认为孔子是博学成名的大学者。
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。

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
