    2023年秋季学期中小学课后服务督导调研工作总结

    三是课后延时服务活动形式多样。课服期间,采用室内活动和室外活动相结合,形式多样:诵读、音乐、速算、书法、象棋、演讲、美术、手工、体育、乒乓球、插花艺术等各种兴趣活动等,培养学生兴趣爱好,确保学生身体、心理的健康发展,更好的提高学生的学习效率,促进学生全面健康成长。该校还创造性开展厨艺分享课,不仅能鼓励孩子们能积极参与家庭劳动,培养同学们的劳动技能,体会劳动的乐趣,也让孩子们学会照顾自己、学会分享、懂得感恩。依照上级文件精神,各学校对课后服务开展情况进行成本核算收取,坚持两个原则:一是自愿原则,二是多退少不补原则;对建档立卡、低保户等家庭经济困难学生免收课后服务费。课后服务费用统一使用,专款专用。学校根据课后服务实际情况及时向学生、家长、社会公示。三、存在问题(一)课后服务能力有待进一步提升。限于我县音体美等专业教师少,课后服务能力还有待于进一步提升。

    大班科学活动课件教案:火箭为什么能上天

    【活动目标】1、让幼儿在探索中了解火箭升天的基本原理,感受科学的神奇。2、引导幼儿在简单的操作中,初步了解物体的反作用力,体会操作的乐趣。3、培养幼儿的动手操作能力,激发幼儿的科学兴趣和探究欲望。【活动准备】神七升天实录、气球若干、放烟花图片、穿天猴(鞭炮的一种)两个。【活动过程】  一、观看升天扣人心弦1、师生一起观看“神州七号”升天的动人场面,认真观察神七的外形特点和发射方法。2、自由讨论问题“火箭为什么能上天?”  (分析:导入开门见山,通过观看神七升天,让幼儿又自主性的提出了这个问题,更加激发了幼儿主动探究的兴趣。)二、探索原理动手操作1、在生活中找现象  教师展示放烟花图片,让幼儿观察,提出问题:  过新年时,小朋友知道烟花是怎样飞上天的吗?  教师户外燃放穿天猴,请幼儿观察穿天猴升天现象。  一起说一说:“此现象和火箭升天有什么相似的地方吗?”2、在操作中找答案  给幼儿每人一个气球,引导幼儿吹上气,把口捏紧朝下,然后快速松手,气球会发生什么现象?(气球会一边向后喷气,一边向天空飞去。)  师:“气球吹的大和气球吹的小,快速松手后,它们飞的一样高吗?”“当气球喷完气后会怎样呢?”  (分析:选择幼儿生活感兴趣、常见的类似火箭升天的现象让幼儿观察,拉进了幼儿与科学的距离,让幼儿觉得科学并不遥远,非常亲切。操作气球飞天,简单易行,让幼儿看小现象,懂大道理。)

    1、明喻: 明喻就是本体、喻体和比喻词都出现的比喻。例句:例如:长城像一条长龙。这个句子中,“长城”是本体,“像”是比喻词,“一条长龙”是喻体。2、暗喻: 暗喻又叫隐喻,只出现本体和喻体,不用比喻词语或用“是、变成、成为、等于”等喻词。例句:例如:山间的云雾构成了一幅精妙的山水画。这个句子中“山间的云雾”是本体,“构成”是比喻词,“一幅精妙的山水画”是喻体。3、借喻: 借喻是只出现用来代替本体的喻体,而本体和喻词都不出现。例句:落光了叶子的柳树上挂满了毛茸茸、亮晶晶的银条儿。这个句子中,本体、比喻词均没有出现,喻体是“银条儿”。

    第21个全国中小学安全教育日国旗下讲话稿

    老师们、同学们:早上好!三月,是春风和煦、万木吐绿、百花盛开、欣欣向荣的美好季节,俗话说:“一年之际在于春。”人们把许多节日或者纪念日都放在了三月,我们走进三月,也就走进了三月的每一个有意义的节日。重要的节日或者纪念日就有下面这几个:3月5日:“向雷锋同志学习”纪念日,3月8日:国际劳动妇女节,3月12日:中国植树节,3月15日:国际消费者权益日,3月21日:世界睡眠日,3月22日:世界水日,3月23日:世界气象日。今天我讲的是大家可能还不太熟悉的一个纪念日:那就是全国中小学安全宣传教育日。这个教育日,是由国家有关部门发出的,确定每年三月最后一个周的星期一作为全国中小学生“安全教育日”。其目的是为推动中小学安全教育工作,降低少年儿童伤亡事故的发生率,保证少年儿童的健康成长。

    老师们、同学们,大家上午好!在全国第22个中小学生安全教育日来临之际,河南省教育厅和郑州市教育局今天联合在郑州市实验高级中学举行安全会议和学生的演练活动。我首先代表河南省教育厅向本次活动的承办单位表示衷心的感谢,向辛勤工作在教育一线的各位老师们表示崇高的敬意,向热爱生活,勤奋学习的各位同学表示亲切的慰问。今年的中小学生安全教育活动主题是“强化安全意识,提升安全素养”。我个人认为要想唱响活动,我们需要落实到每一个环节,需要大家做出以下“四个努力”:首先,校长要做出努力。大家知道,校长是学校安全的责任人,所以我们每一位校长在学校的各项工作当中,应该始终把学校的安全,师生的安全放在各项工作的首位。第二,要完善制度,明确责任。学校的教育教学活动、体育娱乐活动、社会实践活动,后勤保障、医疗服务等各方面,我们都要有完善的制度。要明确每一个单位、每一个部门,包括每一位教职工的责任。大家都知道,我这个岗位应该怎么做,防止出现漏洞。第三,我感觉到要根据各个学校的情况,及时全面的进行安全漏洞的排查,发现隐患及时处置,不留漏洞。校长如果把这些事情做好了,可以说,我们就是一个比较安全的校园,我们的责任就尽到了。

    “拱一拱手,一屁股就坐在上席”,两个动作活画出了夏总甲在乡民面前的傲慢自大。作者接着写他的一番话语:“俺如今倒不如你们务农的快活了。想这新年大节,老爷衙门里,三班六房,那一位不送帖子来。我怎好不去贺节?每日骑着这个驴,上县下乡,跑得昏头晕脑。”“从新年这七八日,何曾得一个闲?恨不得长出两张嘴来,还吃不退。”巧妙地揭示了他为何目中无人和衣服“就如酒篓一般”。二、通过故事情节的前后对比来表达讽刺。第二回中,周进六十多岁了,还以老童生的身份在薛家集观音庵教私塾,一年才十二两馆银,生活窘困,地位低下,村中新中秀才青年梅玖也奚落他。到第七回中,周进中了进士,做了官以后,梅玖就无耻地冒充自己是周进的学生,薛家集的观音庵里也供起了周进的长生牌位。梅玖见了周进早年写的一副对联,贴在墙上,红纸都发白了,竟吩咐和尚用水喷了,剥下来装裱收藏。这一对比既写出了周进做官前后迥然不同的境遇,也写出了秀才梅玖的庸俗势利以及社会上一些人的趋炎附势。所以,《儒林外史》的讽刺,不仅仅是对人物的讽刺,更是对当时社会中各种现象的揭露、控诉和批判。
