精编大学生参加义工活动后个人心得体会合集
我是在学校发出倡议后主动报名的，后来经过学校的开会培训后，于4月11日正式上岗。那天正好是三年级第一批家长义工第一天上岗值勤。我知道家长义工意味着责任和义务，于是提前四五十分钟就到校了。之前因为经常参加家长讲堂活动，女儿的同学们都认识我了，我也能叫出大部分孩子的名字了。所以一进女儿教室，孩子们就热情的围住我，有礼貌问好的，有好奇问东问西的。我摸摸孩子们的头，微笑着边回答问题，边让小鸟一样叽叽喳喳的他们安静下来，让他们拿出书开始早读。然后我到年纪组长杨老师那里领了红袖章签了名后，听她交代了一些注意事项，就兴奋的上岗了。
高二学生国旗下讲话稿：天下兴亡，我的责任
敬爱的老师们，亲爱的同学们：大家早上好！我先给大家讲一个故事：1920年，有一位11岁的美国男孩在踢足球时不小心踢碎了邻居家的玻璃，邻居愤怒不已，向他索赔12.5美元。这12.5美元在当时可谓是天文数字，足够买下125只生蛋的母鸡了。男孩把闯祸的事情告诉父亲，并且忏悔。见儿子为难的样子，父亲拿出了12.5美元说：“这笔钱是我借给你的，一年后你要分毫不差地还给我。”从此，这个男孩每逢周末、假日，便外出辛勤打工。经过半年的努力，他终于挣足了12.5美元，分毫不差地还给了父亲。这个男孩就是后来的美国总统里根。他在回忆这件事时说：“通过自己的劳动来承担过失，使我懂得了什么叫责任。”责任，这两个字很好读，一点也不拗口，但这是个沉甸甸的话题。责任是什么？用歌德的话来讲，就是对自己要求去做的事情有一种爱。这是一个真实的故事。有一个人来他公司应聘，经过交谈，他觉得那个人不适合他们公司的工作。因此，他很客气地和那个人道别。那个人从椅子上站起来时，手指不小心被椅子跳出来的钉子划了一下。那人顺手拿起老板桌子上的镇纸，把跳出来的钉子砸了进去，然后和老板再见。
第十二周国旗下讲话稿：做文明学生，创和谐校园
尊敬的各位老师、亲爱的同学们：今天我演讲的题目是：做文明学生，创和谐校园。文明是文明是一种习惯，他体现着人们的生活态度；文明是一种精神，他体现着人们的风貌；文明是一种素质，告别昨日的无知和粗俗……在我们身边，在一部分同学身上，还存在着一些不文明的行为。例如，在我们的校园内总能见到与我们美丽的校园极不和谐的纸屑和食品包装袋，甚至有的同学认为：反正有值日的同学做清洁工作打扫，扔了又何妨；再例如有的同学在教学楼走廊上追逐打闹，走路推推搡搡习以为常；还有部分同学相互之间讲脏话、粗话。
第十二周国旗下讲话稿：珍爱生命，远离毒品
老师们、同学们：早上好！今天我国旗下演讲的题目是《珍爱生命，远离毒品》。我们对于毒品一直很痛恨，但并不是人人都做到了自觉地抵制毒品、自觉地远离毒品、自觉地与吸毒现象作斗争。在现实生活中，就存在有很多吸毒、涉毒、贩毒的现象，许多美好的生命就在毒品中消亡。据公安机关不完全统计，全国有在册的吸毒者将近100万，近100万人中，70-80%是35岁以下的青年，而青少年已成为最易受到毒品侵害的高危人群。青少年吸毒，严重摧残身心健康。青少年身心尚未发育成熟，一旦吸毒，很容易成瘾，一旦成瘾，就会导致记忆力衰退，营养不良，抵抗力明显下降，各种疾病发生，慢慢走向死亡。青少年吸毒不但给自身带来极大危害，而且造成家破人亡，甚至破坏社会风气，危害社会治安，引发刑事案件，影响和谐稳定。
初二学生国旗下讲话稿——我心中的木棉花
在我们附中的东南角，有一棵高大的木棉树。木棉，是我们广州市的市花，是花园酒店、中国南方航空公司和广州电视台使用的标志，也是XX年第一届亚洲残疾人运动会的吉祥物。每年四月，当北方才刚刚有绿色的影子的时候，火红的木棉已经灿烂耀眼，它火红火红，一朵一朵像绽放的笑脸，像一片一片熊熊的火焰燃烧在枝头，它象征和平、幸福、友谊、安康。（它的花语告诉我们----珍惜身边的人，珍惜眼前的幸福！）可是最近，由于木棉花的花期短、覆盖率少，民间发出是否可以评选“第二市花”的建议，这也使我再次关注我们广州的“英雄花”——木棉。记得小时候，在珠江沿岸，每年燕子唱歌的时候，滨江路的木棉花总是开得最旺盛。吃过晚饭下楼散步，总能捡到一、二十朵掉落的木棉；有时在树下跑过，总能听见那木棉落在地上的声音。每每捡到木棉花，我总是把它们揣在衣服里，到了家，母亲就把较好的收集起来，夏天熬粥。我，就是吃着那又涩又甜的木棉花粥长大的。作为一个土生土长的广州仔，木棉花，就像是我的朋友。
初二学生国旗下讲话稿：构建和谐校园
我是初二7班xxx，今天我讲话的主题是“构建和谐校园”。和谐是事物存在的最佳状态，也是一切美好事物的共同特点。实现和谐，是古往今来人类孜孜以求的美好理想和愿望。而调动一切积极因素构建和谐文明的校园环境也将是一个永恒的主题。构建和谐校园需建立和谐的师生关系。师者，传道授业解惑也，是老师给了我们文化知识的启迪，使我们从无知到有知，从幼稚走向成熟。老师给了我们知识的雨露，我们要全身心的接受，珍惜老师的付出，尊重老师的劳动。师生互敬互爱，从而打造和谐的学习氛围。构建和谐校园需建立建立和谐的同学关系。关心帮助有困难的同学，让他们感受到和谐校园的温馨。

第十二周国旗下讲话稿：友爱，班级和谐的纽带
友爱，是温暖的火苗，融化了人与人之间的冰冷；友爱，是甘甜的清泉，滋润着人与人之间的心灵；友爱，是和谐的纽带，联系着人与人时间的温情。有了它，班级才能像一个家，一个温暖的家，一个充满爱的家。在我们的班级生活中，其实处处见友爱：当同学摔倒，我们帮忙搀扶，这就是友爱；当同学的成绩在下降时，我们主动帮助，这就是友爱；当同学忘带了文具，我们大方借给他，这也是友爱……不过，在我们校园生活中，也时常有一些不和谐事情的发生。多半都是为了些小矛盾而产生纠纷，大家有时明明知道是谁对谁错，可彼此为了面子都不愿拉下赔礼道歉的脸。有时小小的冲动，会带来不小的麻烦！近年来，校园暴力事件在网上频频出现，这些冲动与暴力给自己与他人都带来了无法挽回的伤痛。这些，都在向我们警示：友爱的可贵。
人教版新课标小学数学三年级下册用连乘解决问题说课稿2篇
3、小结比较观察三种方法，提出问题：为什么同一个问题有三种不同的解决方法？学生交流，教师小结：先解决的问题不同，选择的信息不同，图形拼摆的不同，解决的方法就不同，体现数形结合的思想。相同点是：无论思路如何，都是用连乘的方法解决问题。板书课题：解决问题——两步连乘应用题生活中还有很多这样的清况，想不想再尝试一下。（三）联系生活，优化方法，拓展深化，学校有特异为这些参加比赛的同学们购买了矿泉水，出示画面：共有20箱矿泉水，每箱24瓶，每瓶2元，请问学校共要支付多少钱？学生独立完成观察和思考的角度不同，先后选择的信息不同，所以同一道题有不同的解决方法。看来大家多用连乘的方法解决问题有了进一步的理解。生活中类似这样的问题很多，再来看一看：学校定好了水，付了钱，总得运回来吧.出示搬运车搬水到卡车上的画面：搬运车一次搬4摞，一摞3箱，一箱24瓶，请问搬运车一次能搬多少瓶？
