    在活动中只要不影响同伴,幼儿可以用各种动作,随着音乐旋律释放表演激情,而教师始终饱含热情,不断发现孩子的闪光点,并给予鼓励,让幼儿获得成功感。5、活动延伸:(1)与同伴手拉手一起随音乐跳圆圈舞。(2)邀请客人老师一起参与活动。这一环节的设计是将幼儿参与活动的积极性推向高潮,把自己对音乐的感受全部释放出来,再加上客人老师的参与使活动达到高潮,在烘托课堂气氛的基础上,达到了一个大家共同分享活动快乐的目的。6、听音乐走出活动室。六、感悟与反思:俗话说:"教无定法,贵在得法"一堂好的音乐欣赏课应该体现"教学生活化的"教育理念。我想,好的音乐欣赏应该是一种艺术享受,我会在以后的教学实践中,在新的教育理念的熏陶下,和孩子们一起探索,一起成长!本次活动有不当的地方,望各位老师给与批评指正,我的说课到此结束,谢谢!

    4、大胆尝试,用柔和优美的声音演唱歌曲。在熟悉节奏旋律后,解决了难点的基础上,学生对歌曲的学习已是轻松自如了。在此过程中,我采用多种形式让学生练习唱歌:齐唱、分组唱、分男女生唱、个别演唱等多种演唱形式,充分发挥学生的演唱才能。5、成立简易乐队。在唱好了歌的基础上,激发学生用一些简易乐器为歌曲伴奏,利用铃鼓、磁铃为歌曲伴奏。老师用铃鼓示范,磁铃主要用在打击长音处。学生分组练习用铃鼓和磁铃为歌曲伴奏。这样,既培养学生的节奏感,也使他们有一定的成就感。6、创编活动:美的旋律、美的歌词更需要美的舞姿。为了激发学生学舞的兴趣,老师随音乐表演一段,然后重点把傣族的几个基本动作给学生示范一次:孔雀鹤立、孔雀开屏、傣族舞语汇,鼓励学生三五个一组,互相启迪、创作,老师指导、观察,请一些创编的好的同学在前边来表演,音乐再次响起,让每一个学生都动起来,各尽其能、各得其乐、各有所获。整节课都让学生处于愉悦之中。

    1. First, ... then, ... next, ... finally, ...首先,……然后,……接着,……最后,……这是英语中表达做某事的步骤的一种说法。如果步骤较多,还可以说:first-next-after that-later on-finally/at last通常你会听到说英语国家的人在说 first, next, then, finally 和后面的内容时,他们会做一些停顿。这样就能提前告诉听者接下来讲的是一系列的步骤。这一点在朗读和听力中应特别注意。2. how many, how much均为疑问词,同是“多少”,但用法不同。请看:how many修饰可数名词复数,how much修饰不可数名词。但在用法上,同学们常犯如下错误:1) [误] How many are there bananas on the table?[正] How many bananas are there on the table?[析] how many, how much 中的many,much是形容词,常修饰名词作定语,故后面跟名词。2) [误]How much tea are there on the table?[正]How much tea is there on the table?[析] how much修饰不可数名词时,谓语动词用单数。how many与how much的区别可简记为:前how many:问“多少”,复数名词后面跑;how much问“多少”,不可数名词单数好。前者答语用基数词,后者答语用数量关系。

    亿以内数的认识,是在学生认识和掌握万以内数的基础上学习的。生活中大数广泛存在,对大数的认识是万以内数的认识的拓展,也是学生必须掌握的最基本的数学基础之一。本册教材先教学亿以内数的读法和写法,再教学亿以上数的读法和写法,并对数的理论进行整理,在两部分认识数教学中间安排十进制计数法,知道数位,数级,对亿以内数的认识的内容进行归纳整理,也对亿以上数的认识起承上启下作用。加强了数学与现实生活的联系,同时对学生进行综合知识的渗透,从万以内数的认识到亿以内数的认识是学生数概念的又一次扩充。教材提供了较丰富的素材,让学生感受大数,不仅为学生认识大数提供丰富的内容,也为对学生进行国情教育提供了好素材。突出数概念教学,从数学的高度把握十进制原理,培养数感。教学内容的呈现给了学生自主探索和自主交流的空间,也为教师组织教学提供了思路,如:读、写数的法则教材上不给出现成的结论,而是让学生通探究自主过讨论得到。

    二、说教法与学法学生的经验和活动是他们学习数学的基础。本节课的教学本人根据数学新课标的基本理念,精心设计学生的数学活动,充分利用了多媒体教学手段,调动学生多种感官参与学习。让学生在实际中运用所学知识,体现了数学来源于生活,生活离不开数学。整节课以游戏、活动为主线,把教学内容清晰有趣地串了起来,设计了新颖的情景教学和动画故事,尽可能的激发学生的求知欲望。教学过程紧扣教材,层层递进,环环相扣,教师能根据学生的实际适时的引导,使整节课能顺利完成教学任务。有效的学习就是激励学生动手实践、自主探索与合作交流。本课教学中,本人就注意实践操作与游戏活动有机地结合,让学生在玩、交流中思考,在思考中探索,获取新知。三、说教学过程本节课的教学我主要设计了六个环节:提问导入、猜数游戏、实际应用、回顾总结、课堂作业。

    北师大版小学数学四年级上册《正负数》说课稿

    二、说教学目标教学目标是一堂课的中心任务,所有教学环节都是为此服务的,课程标准指出:数学教学不仅要考虑数学自身的特点,更应遵循学生学习数学的心理规律??使学生获得对数学理解的同时,在思维能力、情感态度与价值观等方面都得到进步和发展。根据这一要求和本节教学内容,并结合学生的实际情况,本节课我确定如下学习目标:1、知识与技能在熟悉的生活情景中,进一步体会负数的意义;会用负数表示一些日常生活中的问题,知道正负可以相互抵消。2、过程与方法本节课以小组合作学习为主,让学生利用导学案自学,再对学、群学,最后在班里进行展示。整节课都是学生自主学习,积极探索的一个过程。3、情感、态度与价值观经历独学、交流、合作、展示等一系列活动,通过生生、师生互动获得良好的情感体验,同时让学生感受到了数学在生活中的应用。依据这样的教学目标,再结合学生的年龄特点,我运用了浅显易懂的儿童语言制定了导学案上的学习目标。

    大班数学《8的加法》说课稿

    本节课共分为五大环节来进行教学的1、猜拳幼儿,激趣导入针对大班孩子纯真幼稚、富于幻想的心理特征,因此上课一开始进行复习时,我设计了如下导语:小朋友们,智慧爷爷给你们带礼物啦,表现好的都能得到,让我们先来做一个猜拳游戏吧!点出复习题,在这种刺激下,人人都想当老师眼中的小能手,兴趣一下就调动起来。2、创设情境,探究新知在新课学习中,通过孩子们所喜欢的卡通动物形象-----小兔姐姐,以小兔姐姐邀请小朋友去郊游这一情境贯穿全课,从而激发幼儿学习新知的欲望。通过郊外苹果树上的苹果,引导幼儿感知,探索1+7=87+1=8,并发现数量关系,理解算式的意义,然后出示小鸭图,让幼儿提出数学问题,并列出算式2+6=86+2=83、观察算式,发现加法交换律作为幼儿学习活动的组织者、合作者和引导者,我让幼儿通过小组讨论的形式来发现算式的相同和不同之处,与幼儿一同归纳出:加号两边的数交换位置,得数不变。

    北师大版小学数学一年级上册《跷跷板》说课稿

    一、说教材:“跷跷板”一课是一年级上册第二单元的内容,是在学生学习了比较多少和高矮、长短的基础上进行的体验活动。内容选取学生身边的、常见的、较感兴趣的事物,符合学生的年龄特点与生活经验。本节课的教学让学生通过实践活动,逐步加深对轻重的体验与理解,初步体会借助工具确定轻重的必要性。根据一年级学生的年龄特点和教材的设计意图,教学中应注意创设有趣的情境,使学生产生学习比较轻重的兴趣,让学生在具体的操作活动中独立思考、合作交流,发现比较的方法,使他们获得良好的情感体验,树立学好数学的信心,培养创新意识。二、说教学目标:1、通过比较的活动,让学生感受数学与生活的联系,培养学生仔细观察、认真思考的良好习惯。2、经历比较活动,增强轻重的生活体验。3、通过说一说、掂一掂、称一称的活动,使学生逐步加深对轻重的体验与理解,学会一些比较的方法,体会轻重的相对性。4、通过简单的推理活动,培养学生初步的推理能力。
