/小学生文明礼仪活动总结小学生文明礼仪活动总结???中华民族历来以“礼仪之邦”著称于世，讲文明、懂礼貌是中国人的传统美德。对小学生进行“文明礼仪的养成教育”至关重要。一学期来,我校扎实开展师生文明礼仪教育,使我班学生养成更好的文明礼貌习惯,引导学生从文明礼貌开始，从礼节规范入手，从实际出发，从我做起，从现在做起，切实提升讲文明、讲礼貌、知礼节、守礼仪的自觉性。通过学生“在校学习礼仪、走向社会实践礼仪”，来形成人人讲文明、重礼仪的良好氛围，从而全面提高我班德育教育工作水平。???一、开展以“小学生守则、日常行为规范”的诵读活动我班在开学初以“小学生守则、日常行为规范、小学生礼仪规范手册”为教育读本，扎实开展各类教育活动，从“坐、站、行”、排队出教室、礼貌用语、行为习惯、放学路队等入手，通过规范的指导和训练，养成文明的举止。通过班会课和晨会，让学生了解、掌握礼仪知识与技能，从认知上形成礼仪意识和习惯，引导学生知礼、行礼、守礼，形成学生高尚、文明的道德品质。???二、、开展文明礼仪教育、实践体验活动??（一）学习宣传，提高认识。利用升旗仪式，黑板报等宣传渠道进行宣传，让学生了解活动的意义和目的，自觉地按文明礼仪规范约束自己的言行。开学初的新学年开学、学雷锋活动、母亲节，六一集会礼仪等等都是宣传阵地的主要素材。??（二）加强日常礼仪培训，引领学生形成习惯。以身作则、为人师表形容的是教师示范、榜样作用。学期初，教导处组织我们学习“金正昆教授的教师礼仪讲座”，我们在教学中规范自己的言行，给学生起到良好的示范、榜样作用。学生利用班会学习“学生基本礼仪”和六一集会等方面的礼仪教育。??（三）抓“文明礼仪伴我行”系列活动，提升学生文明素养以“文明礼仪伴我行”为主题，以开展礼仪、礼貌、礼节教育，培养学生良好的文明礼仪习惯为重点内容；以“唱响国歌、遵守规则”为突破口，着眼于全面提高学生的思想道德素质和文明礼仪素质，把“文明礼仪伴我行”主题宣传教育实践活动作为礼仪教育的重要内容来抓，从小处入手，从学生学习生活实际出发，加强校园礼仪教育，培养学生良好的文明礼仪习惯。???1、以“唱响国歌”活动为抓手，规范升降旗仪式。唱准、唱响国歌。并在国旗下讲话中学习文明礼仪内容，培养同学们热爱党、热爱祖国、热爱社会主义的情感，使学生提高自身的文明素养，树立自身的文明形象。另外，在开学典礼之时，上好爱国主义教育第一课，弘扬和培育民族精神，要求学生用顽强的意志克服困难，为祖国的强盛、人民的富裕、自身的未来，自觉地肩负起历史责任。??2、“欢庆六·一”活动中的礼仪教育5月28日下午，我校举行了庆祝六·一活动。同学们以队列、舞蹈、小品剧的形式诠释着“欢庆六·一”的主题。孩子们天真、活泼、可爱的表演引来一阵阵热烈的掌声；教师们真情、真诚的流露感染了在场的每一位师生和家长。全程贯穿着师生的爱：教师对学生的关爱、疼爱；学生对教师的敬爱、喜爱……师生们在活动中感受到节日的快乐，在节目中感染着喜庆六一的热情，这既是一次展示学生素质的舞台，同时也使每位师生接受了一次文明礼仪教育的洗礼。???3、致家长一封信——礼貌待客在假期，我校发放了一封专题的“致家长一封信”，其内容为礼貌待客方面的内容，其目的就是用每一位学生的小手拉起爸爸妈妈的大手，一同学会礼仪知识，践行中华礼仪。
