    新《纲要》指出:教师应成为学习活动的支持者、合作者、引导者。活动中应力求“形成合作式的师幼互动”,因此本活动我除了和幼儿一起准备丰富的活动材料,还挖掘此活动的活动价值,采用适宜的方法组织教学。活动中我运用了1、情景表演法:活动导入部分既要让幼儿发现问题,引出下面一系列的疑问及探索,又要通过幼儿感兴趣的方式设置悬念,因而我设计了小兔出门摔倒这一情节,并通过情景表演的方法启发幼儿思考。2、演示法:是教师通过讲解谈话把教具演示给孩子看,帮助他们获得一定的理解,本活动的演示是运用几何图形的基础上,学会区分异同。此外我还运用了观察法、谈话法等,对于这些方法的运用,我“变”以往教学的传统模式——教师说教,为以幼儿为主体,教师以启发、引导的方式,充分调动幼儿学习的积极性,并以“游戏”贯穿活动始终,让幼儿在玩中获得知识,习得经验,真正体现玩中学,学中乐。

    小班数学《分类》说课稿

    1、设计意图:分类是根据物品的同和异,把物品集合成类的过程,也就是把相同的或具有共同特征的物品归并在一起。对小班幼儿来说分类包含两个层次。一个是求同,就是把相同的物品摆放在一起,比如西瓜和西瓜、糖果和糖果。第二个层次是分类,分类就是把有共同特征的物品放在一起。在本节课中就是在找到一模一样的礼物的基础上再把礼物分成可以吃的,可以玩的和书本三大类。求同是分类的基础,因为求同时的标准是现成的,而分类时要幼儿自己产生标准,他们会把西瓜和糖果都放到食物箱里。所以设计时先让幼儿进行求同活动,提高他们掌握标准的能力,循序渐进,再让幼儿进行分类活动。通过生动的游戏形式,让幼儿在动动、玩玩、做做的过程中,积累有关类的经验,提高幼儿对数学活动的兴趣。2、目标定位:1、让幼儿能找出相同的物品,并知道摆放在一起。2、练习将物品分类,并养成分类摆放物品的好习惯。3、让幼儿通过游戏体验相互合作、和同伴分享的快乐。

    幼儿园数学是一门系统性、逻辑性很强的学科,有着自身的特点和规律,密切联系幼儿的生活,结合幼儿生活实际和知识经验来设计数学活动。此活动选材来源于生活。我们都知道,钟表是幼儿比较熟悉的东西之一。本节课要求幼儿对整点、半点的认识,是幼儿建立时间概念的初次尝试,也为以后“时、分”的教学奠定了基础。选择此教材有一定的必要性,就如《纲要》中所说,“既符合幼儿的现实需要,又有利于其长远发展;既贴近幼儿的生活,选择感兴趣的事物或问题,又有助于拓展幼儿的经验和视野”。一般来说,儿童每天起床、吃饭、上课都要按照一定的时间进行,这样在生活中潜移默化就感知到了时间这一抽象概念的存在。因此,此活动来源于生活,又能服务于幼儿的生活。
