    二、工作中存在的问题经过不断的努力,街道出版物市场的经营秩序已步入正规,各种侵权盗版和违法违规的经营行为已趋于零,娱乐业步入正规稳步发展,但是仍然存在不足之处。消费者没有形成健康的消费观念,造成违规现象屡禁不止。由于盗版音像制品、印刷品相对正版制品价格低廉,质量相差不远,所以人们大多愿意购买盗版制品,有求就有供,造成违法违规产品一直冲击着市场。三、下一步工作*街道“扫黄打非”工作领导小组根据市里下发的通知,还对下一步“扫黄打非”工作进行了安排部署:一是持续坚持“扫黄打非”工作好的经验及做法;二是不松懈、不麻痹、不厌战,久久为功,完成“扫黄打非·新风”集中行动各项工作任务;三是进一步深化、创新“扫黄打非·新风”集中行动工作方式;努力实现全社会全领域全天候保护未成年人氛围更加浓厚、网络空间持续清朗,努力为*街道建设营造更好的环境。

    活动的目标是教育活动的起点和归宿,对活动起着导向作用。根据我班幼儿的年龄特点和实际情况以及布卢姆的《教育目标分类学》为依据,确立了认知、能力方面的目标,其中既有独立表达的成分,又有相互融合的一面,目标为:1、通过观察,幼儿能用较清楚的语句讲述黄豆发芽所需的外部条件以及在不同生长环境中生长的速度有何不同。2、通过一系列的观察种植活动,培养幼儿仔细观察并记录的能力。根据目标,我把活动的重点定于观察黄豆在不同生长环境中生长速度有何不同,讨论为什么会有这些不同?活动的难点是如何用较清晰的语句来说明自己的观察结果。同时在本次活动中重点是发展了幼儿的语言智能和自然观察智能。活动目标:1、通过观察,幼儿能用较清楚的语句讲述黄豆发芽所需的外部条件以及在不同生长环境中生长的速度有何不同。2、通过一系列的观察种植活动,培养幼儿仔细观察并记录的能力。活动准备:1、知识准备:幼儿已经认识了空气,知道空气无处不在,月球上没有空气,万物就不能生长。2、实验准备:幼儿已经初步观察过在一般情况下黄豆的发芽情况;准备好在不同环境(水、沙、土)中已经发芽的黄豆以供幼儿观察。活动流程及环节:提出问题——进一步延伸问题——观察讨论——引出新问题、新实验一、提出问题:1、师提出问题:小朋友,前一段时间我们进行了黄豆发芽的实验,谁来告诉我,怎样才能使黄豆发芽?你看到的黄豆是怎样发芽的?先长什么?再长什么?颜色有些什么变化?

    精编提高团队执行力学习个人心得体会参考范文

    一、要有率先垂范的团队领导:  领导者是团队的核心,是团队的领路人,领导者的执行力决定了这个团队的执行力。领导力就是战斗力,领导力就是执行力!对领导者而言,执行力不只是员工的义务,更是领导者的责任。身教胜于言传,要求员工做到的,领导者必须先做到,正如付老师所言:“要得到什么,就必须先付出什么!。如果领导者有”法不依、有令不行,上有政策、下有对策,那员工又怎么会听从领导的安排?如果说领导者能以身作责、率先垂范,员工上行下效怎么会执行不力?所以说,一个团队的执行力强弱与否,领导者是关键。领导者的一次率先垂范胜过对员工一百次苍白无力的说教!

  • 中班体育教案:“热闹的蚂蚁王国”游戏片断

    中班体育教案:“热闹的蚂蚁王国”游戏片断

    其主要目标是⑴引导幼儿观察蚂蚁,通过各种渠道收集蚂蚁的知识,培养幼儿对探索活动的兴趣。⑵了解蚂蚁特有的一些活动,如“气味语言”“分工合作”“搬运食物”“建筑巢穴”等,并引导幼儿用身体动作表现蚂蚁的活动。⑶培养幼儿关注生活的习惯,并能主动为活动收集相关的材料。⑷通过剪剪、画画、贴贴、做做等活动,培养幼儿动手操作的能力。⑸通过和蚂蚁的一系列接触,发展幼儿的想象创造能力,培养幼儿交往协作的能力。⑹培养幼儿亲近动物,喜爱动物的情感。⑺ 教师和幼儿共同体验游戏的快乐。以下是我们汲取的一些有关蚂蚁的活动片断,生动地再现了孩子们用已有的生活经验不断生成发展出更为生动有趣的、丰富的游戏情节。片断一:有趣的小蚂蚁午后的阳光暖暖的照在我们身上,小朋友们手拉着手悠然地走在这午后的阳光里。“看,那是什么呀?”“好象是蚂蚁吧。”“它们在干什么?”“在搬东西。”“好象是在搬草片儿。”“不对,是面包屑。”“蚂蚁那么小,怎么搬得动那么重的东西。”“你没看见有好几个蚂蚁在一起搬吗?”“对,大家一起搬就搬得动了,对吧?”“是的。”“小蚂蚁搬面包屑干嘛?”“当然是搬回家吃了。”“蚂蚁那么小,怎么吃东西呢?”“当然是用嘴巴吃了。”“蚂蚁那么小没有嘴巴。”“瞎说,蚂蚁有嘴巴,不然,它不要饿死吗?”“蚂蚁喜欢吃什么呀?”“好象喜欢吃甜甜的东西吧。”“是的,我以前看见过它们在搬饼干屑。”“对,我还看见它们都爬在我吃剩的西瓜皮上。”“是的,是的,我也看见过,而且,有许多许多蚂蚁。”“你说,它们怎么会知道的,真奇怪!”“它们是看到的。”“不,是闻到的。”(评析:无意中的发现,引起了孩子莫大的兴趣,他们的好奇心和兴奋的表情给了我们组织这次游戏活动的灵感。)教师拿来放大镜和昆虫盒,和孩子们一起进入了奇妙的蚂蚁世界。幼:我们去找一点糖来引引蚂蚁吧!幼:好的,我也去拿点饼干屑。幼:蚂蚁会住在哪里呢?幼:垃圾箱旁边,我看见过的。幼:不对,是草丛里。幼:是的,有一次我也在草里发现它们在爬呀爬,很好玩的。幼:好象是泥土里,我在电视上看到过。幼:看,这里有这么多洞!幼:嘘,别讲话,不然,他们就不出来了。幼:把饼干放在蚂蚁洞口,让它们出来搬。师:你在干嘛?幼:我在挖洞,让蚂蚁出来。

    部编版语文八年级上册《中国石拱桥》教案

    目标导学四:揣摩语言,把握说明效果为了准确地说明事物,说明文很讲究用语的分寸。请品味下面的语句,回答括号内的问题。1.石拱桥在世界桥梁史上出现得比较早。(“比较”一词去掉行吗?)明确:不行,“比较”程度较轻,是与其他桥梁比较而言,这样表达比较准确。2.这种桥不但形式优美,而且结构坚固。(“不但”“而且”能否删去?“结构坚固”“形式优美”能否调换顺序?)明确:“不但”“而且”不能删去,如果删去,它们之间的关系就变成了并列关系。先说外观,再说功能,符合人们的认识逻辑。并且对于桥来说,其实用价值远远重于形式,所以二者不能调换顺序。3.《水经注》里提到的“旅人桥”,大约建成于公元282年,可能是有记载的最早的石拱桥了。(“大约”“可能”“有记载的”有什么表达效果?)明确:“大约”“可能”都表示不确定,只是推测的情况。“有记载的”使话语的根据更具可靠性。
