3、文化的力量。为了使学生能辨证地分析文化的力量，我设计了两个问题进行探讨：（1）是不是任何文化都能起促进作用？（2）你在听或唱国歌时感受到一种什么样的力量？这样，学生在对比中学会辨证地分析文化的力量——先进的、健康的文化能促进社会发展和个人成长；落后的、腐朽的文化则阻碍社会发展和个人成长。同时还能提高学生的文化赏析能力，从而引导学生装自觉参加健康有益的文化活动，抵制不良文化的影响，投身到社会主义精神文明建设中去。关于课堂练习，我准备了5个针对性比较强的选择题，从而加深巩固本框题的重难点知识。最后，播放歌曲《走进新时代》，展示本课知识结构，指出本框题需重点掌握的问题，结束本课教学。课后作业，我设计了这样一个辨析的题目：文化是人们创造的全部财富的总和，它是人类特有的现象。

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。

大班健康教育活动：身体的秘密教案
在本月开展多元智能创意课程《变变变，长大了》主题活动时，有一个分题活动是“身体的秘密”，孩子们一看到书中男女小朋友入厕的情景，立即炸开了锅。同时，他们对两性问题表现出的早熟倾向引起了我们的关注：有的孩子在课后扭住我提了很多他关于成人生活的困惑；还有的男孩子竟忍不住好奇，偷偷跑进女厕所想一窥究竟……（略）于是，我们决定对孩子们现阶段最为关注的话题作出正面的、积极的回应，同时对学前教育阶段如何开展启蒙“性教育”进行探索，生成了本次活动“身体的秘密”。活动目标：1、科学、正确地面对性话题，学会尊重自己和别人的身体。2、有初步的自我保护意识，了解基本的防卫方法。3、引导幼儿积极地思维，自由地表达。活动准备：1、幼儿的准备：活动前的调查记录，对两性的区别有了初步的认识；2、教师的准备：l 搜集大量的性教育资料（今日说法、《画说性》等），以应对课堂上孩子们的突发提问；l 角色分工、互助协调； 布置有关两性知识的活动区角（包括人物、动物），提供较为丰富安全的可操作材料。活动过程： 一、谈话引入，讲解什么是“性”。1、请小朋友以性别分为男女两组，两名老师明确分工。幼儿阐述自己对不同性别的看法，即“男女有什么区别”。2、提问引发思考：什么是“性”？小结：“性”是和我们的身体密切相关的，不关是从头发的长短就能判断性别的，更重要的是我们身体的某些部位，是代表着性别差异的。是那些部位呢？就是我们穿衣服遮起来的部位。

教育活动课“团结就是力量”教案
【设计意图】在小学阶段，团结合作精神是学生进行良好的人际交往所必备的心理品质，也是教师塑造良好的学生班集体所必须加以培养和训练的，是小学生生活心理教育的重要内容。“学会学习，学会创造，学会合作，学会生存”已成为二十一世纪教育的主题。团结是一种力量，是我们不断前进的动力。团结协作不只是一种解决问题的方法，更是一种道德品质。它体现了人们的智慧，是社会生活中不可缺少的。而现在小学生多为独生子女，在家庭、学校生活等多层面中表现出不合群，不善于与人合作的弱点。因此，培养小学生的合作意识，合作精神和合作能力非常必要。在本节课的教学中，本着充分发挥学生的主体性，师生互动性原则，引导学生主动探究，学会团结合作。针对学生的实际情况，进行教学环节的设计。【活动目标】1、了解团结合作的重要性和必要性，体验团结合作带来的快乐情感，增强合作意识。2、初步掌握如何进行团结合作，培养合作能力。【活动内容】小学生人际交往心理辅导。【活动方式】联想活动、游戏、绘画、艺术欣赏、集体讨论。【活动对象】小学二年级学生【活动时间】40分钟。【活动准备】一次性筷子、长凳、课件、彩色笔等。
《感恩教育》主题班会教案（1）
（一）感受父母的爱 主持人：无论你身在何地，有一个人，她永远占据在你心中最柔软的地方，你愿用自己的一生去爱她；有一种爱，它让你肆意索取，享用，却不要你任何回报。这个人，叫“母亲”，这种爱叫“母爱”。 父爱是山，无论你有多大的困难，他总是你依靠的屏障；父爱是路，无论你走到哪里，他都伴你延伸，为你指点迷津，护你一路走好。让我们一起感受伟大的母爱和父爱。 1、故事1、汉朝时，大梁有个叫韩伯愈的人，本性纯正，孝敬父母，是一位著名的孝子。他的母亲对他管教很严格，稍微有点过失，就举杖挥打。有一天伯愈在挨打时，竟然伤心哭泣。他母亲觉得奇怪，问道：“往常打你时，你都能接受，今天为什么哭泣？”伯愈回答道：“往常打我我觉得疼痛，知道母亲还有力气，身体健康，但是今天感觉不到疼痛，知道母亲身体衰退，体力微弱。所以伤心禁不住流下了泪水。并不是疼痛不甘心忍受。”说明了他非常孝敬母亲。
《感恩教育》主题班会教案（2）
请听歌曲:《烛光里的妈妈》。学生回想自己父母,然后老师按语：不知不觉，我们长大了。曾几何时，岁月的年轮写在父母的身上。他们的脸上爬上了几条皱纹，头发中映出几根银丝。他们的步履不再矫健了，他们的腰背部不再笔挺了。这一切都是为我们操劳的呀！今天我们要真诚地、大声地说一声：爸爸妈妈，感谢你们，你们辛苦了！感恩老师班长主持人：十月的阳光如此灿烂，十月的校园如此深情。似滴滴雨露滋润着我们求知的欲望；似缕缕阳光温暖着我们心中的希望。让我们一起怀着一颗感恩的心，一起大声高呼：我爱你，敬爱的老师！我们的每一点知识，我们的每一个进步，都渗透着老师的汗水和心血。让我们用最真挚的感情，把最动人的诗篇送给我们敬爱的老师。
《习惯养成教育》主题班会教案
事实上，良好的行为习惯，是保证我们顺利学习的前提，也是树立健康人格的基础。在学校没有良好的行为习惯的同学就可能目无纪律，不讲卫生，扰乱班级的学习环境。相反，如果我们养成了文明的行为习惯，学习环境就一定是良好的、有序的。我们知道：一个学校的学生具有良好的文明行为习惯，才能构建出优良的学习环境，创设出优良的学习气氛。现在，我们正处于人生中最关键的成长时期，我们在这个时期的所作所为，将潜移默化的影响到我们自身的心理素质，而文明的行为就在帮助我们提高自身的心理素质，同时也完善了自身的道德品质，如果我们不在此时抓好自身道德素质的培养，那我们即使拥有了丰富的科学文化知识，于人于己于社会又有何用呢？所以，我们首先应该做一个堂堂正正的人，一个懂文明、有礼貌的谦谦君子，然后才是成才，不能做一部单纯掌握知识技能的机器，而要成为一个身心和谐发展的人。文明就是我们素质的前沿，拥有文明，那我们就拥有了世界上最为宝贵的精神财富。行为习惯的表现优异，也能在学风建设中反映出来。
