国旗下的讲话稿：让我们与文明同行
老师们、同学们：早上好！今天我要讲的题目是“让我们与文明同行”。在讲这个话题之前，我想先问问同学们，当你行走在马路上而无意间看见路面上有一口痰迹时，你会怎么想？怎么说？当你行走在校园里而无意间看见地面上有一张纸屑时，你又会怎么想？怎么做呢？在这里先给大家讲两个事例：第一个事例是：有人发现在新加坡这个通用英语的国家里，他们的公共场所的各种标语大多是用英语书写的。但其中的一些涉及文明礼貌的标语，如“不准随地吐痰”、“禁止吸烟”、“不准进入草坪”等却用中文书写。这是为什么呢？人家回答：因为有这些不文明行为的大数是中国大陆的游客。为此，到新加坡考察的一位中学校长语重心长地说：不文明行为也是国耻。第二个事例是：据中央电视台报道，国庆节后的天安门广场，随处可见口香糖残迹，显得格外刺眼，40万平方米的天安门广场上竟有xx万块口香糖残渣，有的地方不到一平方米的地面上竟有9块口香糖污渍，密密麻麻的斑痕与天安门广场的神圣和庄严形成了强烈的反差。以上两个事例表明，文明的一切都是由细节构成的，通过这些细节，我们看见了文明离我们国家还有一定距离。
国旗下的讲话稿：我与祖国共奋进
今天我以你为荣，明天你以我为傲。你说你来了，来得这么匆忙，我还没有来得及赶上你给予我时代的步伐，就走了。你从成立以来经历了时代的变迁，经过了文化大革命，经历了改革开放，经历了21世纪的繁荣昌盛，而今你要为实现伟大的中国特色社会主义，实现共同富裕而离开，我只有追寻你时代的背影，用一生，不，来生来追逐。祖国啊，你是我心中难灭的光辉，你是守侯了一千年的期望，祖国啊，我是你眼中冉冉升起的一缕阳光，是你振兴中华的生命力量.今夜，我又来到你的窗前，为你点缀星光灿烂的烟火，将坚持科学发展观的希望火花化作祝福，捎向天空，遥寄给远方的你。我不能忘记我们共同努力的抗战8年，我不会忘记我们共同奋进的改革开放二十年，我更不会忘记我们即将建设的实现小康社会的宏伟目标。我今生对你的唯一要求就是你要坚持"科学技术是生产力"的引领，带着改革开放的羽翼翱翔于天空，自由地生活，实现梦想而奋进。我今生对你最大的期望就是你能继承三个代表的重要思想方针，跟随着时代奋进的步伐，成为世界的壮举。你奋斗了大半辈子，你应该懂得珍惜我们共同创造的"果实"。
大班语言《古塔上的鸟》说课稿
二、教学目标。根据大班幼儿早期阅读的特点，以及大班幼儿在阅读学习方面的实际情况，我从知识、情感、能力三方面提出了本次活动的目标：1、有序观察阅读单页多幅画面，感知故事内容。（大班幼儿阅读的内容，一般是以单页多幅画面出现的，具有按顺序阅读的要求。但是个别幼儿思维过程中常呈现一种无序状态，思维具有跳跃性，因此，掌握阅读技巧也是本次活动的重点。）2、积极参加讨论活动，通过观察新旧城市的变化，喜欢上绿色新城市，产生绿化城市的愿望。（大班的孩子喜欢交流，他们的交流欲望较中班有了更大的提高，所以这个目标不仅满足了大班孩子的这一欲望，而且在交流中升华了他们的情感。）3、能与同伴合作用剪贴的方式创建新城市，增强合作剪贴能力。（这是本次活动的能力目标。）三、教学方法。根据纲要精神：要创造一个自由、宽松的语言交往环境，支持、鼓励、吸引幼儿与教师、同伴或其他人交流的乐趣，所以我在本次活动中采用了讨论交流法，讨论能开拓幼儿的思维，是激发幼儿言语的重要方法，而交流是幼儿学习阅读和检验阅读能力的基本手段。我在幼儿熟悉故事情节的基础上，让他们讨论交流，进一步感受故事的意义所在，不仅充分发挥了教育中的幼儿同伴资源，更让幼儿体验到了与他人交谈、交流语言的乐趣。纲要指出：教育不是让幼儿重复经验，而是把幼儿的已有经验重组和改建，所以教师要了解幼儿的现有经验，然后帮助他们整理、迁移、提升经验。在本次活动中，我就运用了经验迁移法，在了解幼儿喜欢绿色以及知道绿色对人类的好处的基础上我把这些已有经验迁移到故事中，让幼儿明白小鸟孤独的原因，揭示为什么最后人们会给自己的城市绿色美化的背后含义。

童年的发现（说课稿）
一、 说教材1.教材分析《童年的发现》讲的是作者童年时的一个发现，反映了儿童求知若渴的特点和惊人的想象力。课文先概述了作者童年时的发现，然后具体叙述这项发现的经过，最后写这个发现在几年后老师讲课时得到证实。根据文章的特点，我选用了语文主题丛书《金色童年》中的《少年爱迪生》作为拓展。两篇文章主题相似，爱迪生小时候也遭受了和文中费奥多罗夫相似的遭遇:“世界上重大的发明与发现，有时还面临着受到驱逐和迫害的危险。”
新年的礼物 说课稿
一、说教材《新年的礼物》是一年级上册《道德与法治》第四单元、第十六课，本课主要通过活动与学习，让学生懂得在自己成长的过程中，收获是什么、收获从哪里来、学会感恩以及教给学生规划新年的期望和心愿。课文分为三大部分，第一部分是新年的收获，主要通过课本上的图片让学生了解什么是收获。第二部分是收获哪里来，主要通过自我的努力和外部因素的帮助，来了解收获的途径。第三部分是新年的心愿，让学生在动手动脑制作贺卡的同时，扩展思维，训练能力。二、说学情通过快一学期的学习，孩子们懂得了自己的事自己做，但对于“收获”的理解还不是很明晰，如何规划新年的期望和心愿，还急需教师的正确引导。三、教学目标：1.通过了解新年的收获，为自己和同学的成长感到快乐，乐观积极地面对生活。2.通过分享交流新年的收获途径，进一步认识自己，了解同学。3.知道自己的进步离不开许多人的帮助，学会感恩。
装扮我们的教室 说课稿
说教材此课根据《课程标准》“负责任，有爱心的生活”中的第九条“喜欢集体生活， 爱护班级荣誉”，“愉快、积极的生活”中的第六条“在成人帮助下，能定出自己 可行的目标，并努力去实现”，以及“动手动脑，有创意的生活”中的第五条“能 积极地出主意、想办法来扩展游戏或活动”而设计。其目的在于通过“装扮我们的 教室”这样一个从观察、设计到动手实施的综合性活动，结合前面三课所学内容， 深化学生的集体感和集体荣誉感，引导他们超越自我，走向广阔的公共生活。学情分析首先，二年级的学生在各方面有了很大进步，尤其是对“集体”的认知程度有所提高。但是他们多数还处于自我中心的阶段，缺少从整体和全局思维出发思考问题的能力，不易把个体的活动与整体的活动联系起来。其次，学生的年龄决定了他们的动手能力和思维能力有限，他们想到的可能更多是局部的、具体的一些做法；在实施过程中，学生可能会没有目标、没有主题，随心所欲地进行。另外，他们都能认识到自己是集体中的一员，班集体是自己的另一个家，有责任让它更美，但大部分孩子仅仅是有这样的愿望，而不知道如何将意识转化为行动，真正参与到装扮教室这一活动中。
