/小學(xué)生文明禮儀活動總結(jié)小學(xué)生文明禮儀活動總結(jié)???中華民族歷來以“禮儀之邦”著稱于世，講文明、懂禮貌是中國人的傳統(tǒng)美德。對小學(xué)生進(jìn)行“文明禮儀的養(yǎng)成教育”至關(guān)重要。一學(xué)期來,我校扎實(shí)開展師生文明禮儀教育,使我班學(xué)生養(yǎng)成更好的文明禮貌習(xí)慣,引導(dǎo)學(xué)生從文明禮貌開始，從禮節(jié)規(guī)范入手，從實(shí)際出發(fā)，從我做起，從現(xiàn)在做起，切實(shí)提升講文明、講禮貌、知禮節(jié)、守禮儀的自覺性。通過學(xué)生“在校學(xué)習(xí)禮儀、走向社會實(shí)踐禮儀”，來形成人人講文明、重禮儀的良好氛圍，從而全面提高我班德育教育工作水平。???一、開展以“小學(xué)生守則、日常行為規(guī)范”的誦讀活動我班在開學(xué)初以“小學(xué)生守則、日常行為規(guī)范、小學(xué)生禮儀規(guī)范手冊”為教育讀本，扎實(shí)開展各類教育活動，從“坐、站、行”、排隊(duì)出教室、禮貌用語、行為習(xí)慣、放學(xué)路隊(duì)等入手，通過規(guī)范的指導(dǎo)和訓(xùn)練，養(yǎng)成文明的舉止。通過班會課和晨會，讓學(xué)生了解、掌握禮儀知識與技能，從認(rèn)知上形成禮儀意識和習(xí)慣，引導(dǎo)學(xué)生知禮、行禮、守禮，形成學(xué)生高尚、文明的道德品質(zhì)。???二、、開展文明禮儀教育、實(shí)踐體驗(yàn)活動??（一）學(xué)習(xí)宣傳，提高認(rèn)識。利用升旗儀式，黑板報等宣傳渠道進(jìn)行宣傳，讓學(xué)生了解活動的意義和目的，自覺地按文明禮儀規(guī)范約束自己的言行。開學(xué)初的新學(xué)年開學(xué)、學(xué)雷鋒活動、母親節(jié)，六一集會禮儀等等都是宣傳陣地的主要素材。??（二）加強(qiáng)日常禮儀培訓(xùn)，引領(lǐng)學(xué)生形成習(xí)慣。以身作則、為人師表形容的是教師示范、榜樣作用。學(xué)期初，教導(dǎo)處組織我們學(xué)習(xí)“金正昆教授的教師禮儀講座”，我們在教學(xué)中規(guī)范自己的言行，給學(xué)生起到良好的示范、榜樣作用。學(xué)生利用班會學(xué)習(xí)“學(xué)生基本禮儀”和六一集會等方面的禮儀教育。??（三）抓“文明禮儀伴我行”系列活動，提升學(xué)生文明素養(yǎng)以“文明禮儀伴我行”為主題，以開展禮儀、禮貌、禮節(jié)教育，培養(yǎng)學(xué)生良好的文明禮儀習(xí)慣為重點(diǎn)內(nèi)容；以“唱響國歌、遵守規(guī)則”為突破口，著眼于全面提高學(xué)生的思想道德素質(zhì)和文明禮儀素質(zhì)，把“文明禮儀伴我行”主題宣傳教育實(shí)踐活動作為禮儀教育的重要內(nèi)容來抓，從小處入手，從學(xué)生學(xué)習(xí)生活實(shí)際出發(fā)，加強(qiáng)校園禮儀教育，培養(yǎng)學(xué)生良好的文明禮儀習(xí)慣。???1、以“唱響國歌”活動為抓手，規(guī)范升降旗儀式。唱準(zhǔn)、唱響國歌。并在國旗下講話中學(xué)習(xí)文明禮儀內(nèi)容，培養(yǎng)同學(xué)們熱愛黨、熱愛祖國、熱愛社會主義的情感，使學(xué)生提高自身的文明素養(yǎng)，樹立自身的文明形象。另外，在開學(xué)典禮之時，上好愛國主義教育第一課，弘揚(yáng)和培育民族精神，要求學(xué)生用頑強(qiáng)的意志克服困難，為祖國的強(qiáng)盛、人民的富裕、自身的未來，自覺地肩負(fù)起歷史責(zé)任。??2、“歡慶六·一”活動中的禮儀教育5月28日下午，我校舉行了慶祝六·一活動。同學(xué)們以隊(duì)列、舞蹈、小品劇的形式詮釋著“歡慶六·一”的主題。孩子們天真、活潑、可愛的表演引來一陣陣熱烈的掌聲；教師們真情、真誠的流露感染了在場的每一位師生和家長。全程貫穿著師生的愛：教師對學(xué)生的關(guān)愛、疼愛；學(xué)生對教師的敬愛、喜愛……師生們在活動中感受到節(jié)日的快樂，在節(jié)目中感染著喜慶六一的熱情，這既是一次展示學(xué)生素質(zhì)的舞臺，同時也使每位師生接受了一次文明禮儀教育的洗禮。???3、致家長一封信——禮貌待客在假期，我校發(fā)放了一封專題的“致家長一封信”，其內(nèi)容為禮貌待客方面的內(nèi)容，其目的就是用每一位學(xué)生的小手拉起爸爸媽媽的大手，一同學(xué)會禮儀知識，踐行中華禮儀。
