花钟教学设计一等奖篇五
人教版义务教育课程标准实验教材三年级上册《花钟》是一篇说明文,虽然介绍科普知识,但是课文语言优美,生动地展现了不同花的开放,又通过举例具体地说明了花开的原因。如何使学生对相关知识有所感知并产生积极的探究欲望,又能促进语文能力的发展?根据《语文课程标准》知识能力、过程和方法、情感态度和价值观三维度相互渗透、融为一体的课程目标,我循着学生的情感变化进程,努力引导他们从语言的角度去走近花钟、看懂花钟、品味花钟、质疑花钟和研究花钟,和学生一起站在语言的门厅里聆听花钟独特的报时。
1、教师引导:同学们,咱们都见到过各种各样的时钟,有的挂在墙头,有的摆在床头柜上,瞧,我的手机上也装着小小的时钟,它们能告诉我们时间。那你们知道花钟吗?
2、当学生作出阅读前的猜想后,教师提出初读课文要求:究竟什么是花钟,咱们读读课文就会明白。请同学们自由读课文,遇到难读的地方多读几遍,争取把课文读正确,读流利。
3、当交流完什么是花钟?后,教师直接引入:课文第三段就是这样写的,自由读读这一段,你还读懂了什么?
(1)你是不是觉得很有趣?有趣在哪儿?
(2)课文为什么说大致?
(3)怎么个陆续开放?并一起读出花钟的有趣。
《语文课程标准》指出:语文课程必须根据学生身心发展和语文学习的特点,爱护学生的好奇心、求知欲,充分激发学生的主动意识和进取精神。现实生活中,学生对于花其实并不熟悉,但对于花钟这种新奇的事物是充满兴趣和疑问的。因此,我循着学生的情感起点,先引导学生看课题质疑,进而快速地直面课文,并马上落脚在末尾一段,通过自读,初步了解什么是花钟。
4、引导学习第一段:可是,你能看懂花钟吗?是啊,要看懂花钟就得知道什么花几点钟开。咱们知道花开的时间吗?哦,第一段就写了花朵陆续开放。植物学家是通过留心观察,知道花朵的开放时间的,咱们现在只有通过读课文了解。读读几点钟开什么花?
5、反馈时教师大屏幕出示花钟图,说:同学们看,这儿也有个钟面,但没有时间标志和指针,这是一座圆圆的花圃,要是把课文里写到的这些花种在上面,当它们陆续开放时,你能马上认出它们,并说出是几点钟吗?教师播放花朵陆续开放,学生争相说出几点什么花开放。
6、教师指着大屏幕说:这圆圆的花圃上,鲜花朵朵,陆续开放,就在告诉我们时间,这就是花钟,你觉得这是一座怎样的时钟?
语文教学应激发学生的学习兴趣,注重学生自主学习的意识和习惯,为学生创设良好的自主学习环境。由你能看懂花钟吗?激起了学生对课文第一段的学习兴趣。教师播放花朵陆续开放的课件,让学生看懂花钟,则是带学生进入了自然的情境,让学生感受到了花钟的鲜艳与芳香,感受到了它的多种功用、它的神奇与独特。由此,为研究这一段语言的表达做好了情感准备和背景铺垫。
1、顺着学生的回答:美妙的花钟、神奇的花钟、令人心旷神怡的花钟教师提出要求:课文是怎么介绍这么美妙的、神奇的花钟的。咱们再静静地、细细地读读第一段,去寻找,去发现课文写得好在哪儿?反馈时,引导学生说出以下几点
(1)把花的开放写得具体、生动;
(2)同样写开花,课文用了不同的写法;
(3)写每一种花开放,都是根据这种花的特点。
2、进一步引导:课文是怎么写每一种花开放的。你觉得哪一句写得好,可以画出来,再仔细读读、想想。在学生交流时,教师大屏幕出示相关花朵开放的照片,同时,注意点拨语言表述的准确、生动、具体:(1)花朵的形状,如喇叭;(2)花朵的色彩,如红艳艳;(3)花朵的形态,如昙花含笑一现、万寿菊欣然怒放。最后,教师小结:每一种花的开放,课文可不是随便写写的,而是根据花的色彩、大小、开放的样子这些特点,有着不同的写法,把花朵陆续开放写得丰富而有变化,让咱们仿佛看见花朵千姿百态。
3、引导笔练:发现没有,还有两种花,课文好像没有写出它们开放的样子,咱们能不能写写它们的开放,选择一种花写出它是怎么开放的。交流评价时突出:咱们把这两种花的开放写美了,而且也学会了用不同的方法表达。
4、引导朗读:鲜花用自己的开放这种特殊的、美好的方式告诉你、我、我们大家时间。咱们也来做做花钟,读出花的陆续开放,你喜欢做哪一种花,就自己站起来大声读她的开放。现在,让咱们用美妙的朗读、用开放这种美好的方式告诉大家时间。
《语文课程标准》指出:应该让学生更多地直接接触语文材料,在大量的语文实践中掌握运用语文的规律。课文第一段最大的语言特色就是写每一种花开放,都是不同的表达。要让学生自己感悟到丰富而有变化的表达,只有通过读。《语文课程标准》也指出:阅读教学的重点是培养学生具有感受、理解、欣赏和评价的能力。先引导学生自读自悟,去发现课文第一段写得好在哪儿;在总体感受语言特点的基础上,再具体研读描写花开的句子,让学生通过朗读去感受、欣赏、评价每一句话的好处、每一种花的情趣;最后,引导学生尝试写一写夜来香和午时花的开放。如此这般,学生在品味花钟独特的报时方法时,也感悟到了课文语言表达的独到。
1、鼓励质疑:读到这儿,你有什么发现和问题吗?学生可能会问:
(1)我还想知道,还有什么花在几点钟开放?教师回应:老师还知道几种花朵的开放时间,边大屏幕出示照片,边介绍:蒲公英在早晨六点开花;紫茉莉约下午四点开放;下午五点,白香水百合开放;晚上六点,丝瓜花开放并引导:回家也可以观察一下你家里的花大约几点钟开放,几点钟闭合。
(2)为什么不同的花开放的时间不同?教师引导:咱们接着就来研究这个问题。
2、引导自由读第二段,找找原因,当学生找到答案后出示文中两个概括写的重点句,并问,植物开花时间与温度、湿度、光照有密切的关系,怎么个密切?再读读有关的句子想一想。学生交流后,教师小结:昙花在九点左右开花原来是由周围条件决定的。看来,课文举了昙花这个例子就一下子讲明白了植物开花时间与温度、湿度、光照有密切关系的科学道理。继续引导:而有的花开放时间又与昆虫活动时间相吻合,怎么个吻合?为什么会吻合?
3、接着,教师随机大屏幕出示照片牵牛花、睡莲、夜来香、午时花、万寿菊,这些花为什么有它们自己的开放时间,根据你的了解大胆猜测,举例来说说。根据学生猜想,教师小结:刚才咱们也举了例子来说明为什么花朵开花的时间不同,有的同学推测得很有道理,像个小小植物学家。但是,这些花开花的时间究竟与温度、湿度、光照有关,还是跟昆虫有关,甚至跟其它因素相关,咱们在课后可以去查阅资料进一步再研究。
课文第二段的语言特点是用具体的例子说明抽象的结论。教师先引导学生通过读懂昙花开花时间的形成来理解花开时间与湿度、温度、光照的密切联系,进而也明白花开与昆虫活动的联系。然后引导学生根据自己的生活经验和课前知识准备说说其它花朵开放时间的形成。在一种类似于科学探究的情境中,在语言的表述和积累中,学生进一步感悟了课文以举例作具体说明的方法,在感受每一种花独特的开放的同时,也感悟到了课文表达的恰如其分。
诚如《花钟》一文用美好的语言介绍花的时钟,诚如花钟用花朵美好的开放告诉人们时间,诚如那位植物学家在用一颗美好的心研究自然、留意生活,《花钟》一文的教学,我领着学生,和他们一同绽放着花开般的美好心灵,站在语言的门厅里,于是,我们聆听到了花钟独特的报时。

知识与能力目标:会认8个生字,会写14个生字,正确读写“争奇斗艳”等词语;正确、流利、有感情地朗读课文,背诵自己喜欢的部分,学习运用多样的句式表达。
情感与价值目标:激发观察的兴趣,初步培养学生留心观察周围事物和认真思考的习惯。
感悟鲜花开放的不同表达方式。
在理解课文的基础上,学习用不同的说法表达同样的意思。
为了顺利达成目标,我分两课时进行教学:第一课时,初读课文,感知课文内容。这里,我主要是写第二课时的教学流程。
一、悄然入情赏花钟
同学们,上节课我们初步感知了课文内容,现在请大家看:这就是世界上最早发明的瑞士日内瓦大花钟,瑞士素有“花园之国”和“钟表之乡”的美誉。能工巧匠绝妙地将花卉同钟表的制造结合起来,别出心裁地创造了“花钟”。花钟上有哪些花儿?这些花分别是什么时候开放呢怎么能组成一座钟呢?你们想知道吗?让我们一起去读书,发现其中的秘密吧。
二、品读美文识花钟
引领学生学习课文第一自然段,分这样几个步骤指导学习的。
1.指名读文,找中心句。指读,其他同学边听边找出本段的中心句,然后用课件出示中心句。告诉学生找中心句是归纳段意的方法之一。
2.轻声读,找花名。再让学生轻声读描写花开的句子,找一找课文中写了哪几种花。多媒体展示:把收集到的9种鲜花的图片一一展示给学生欣赏,配上音乐和简单的介绍,为学生的品句作铺垫。
3.用自己喜欢的方式读文本,教师及时点拨。
4.读写结合,学表达。
以课后练习题为蓝本,让学生在填空中感悟用词的准确和不同的表达技巧。
(1)用课件出示“四点牵牛花开了,五点蔷薇花开了,七点睡莲开了,十二点午时花开了……”让学生和课文中的句子对比,然后进行体会交流。
(2)同学们,你们平时观察到哪些花在什么时间开放呀?借机让学生结合平时观察,生活积累,学习作者的表达方式,填补课文中省略号的空白。
(3)图文结合,师读花名,学生读花开的部分,引读美文,让教师、学生、文本甚至与编者融为一体。
三、合作交流探花钟
学习课文第二段。采取了小组合作学习的方法。
出示小组合作学习卡片:
1.读一读:默读课文第二自然段。
2.议一议:在小组里讨论讨论:为什么不同的花开放的时间不同?
3.填一填,一天中造成不同植物开花的时间不同的原因是:
(1)植物开花的时间,与( )( )( )有着密切的关系;
(2)还有的花,需要( )传播花粉才能结出种子,因此与( )有关。
4.说一说:昙花为什么会在九点含笑一现?用自己的话说一说。
按照三个层次进行:自主学习──小组交流──全班汇报的流程,共同学习。
四、拓展延伸编花钟
引导学习课文第三段,学生齐读课文第三自然段。
1.师再次播放大花钟让学生欣赏:瑞士的日内瓦花钟把美丽的鲜花与钟表奇妙地结合在一起,给人以美的享受,各国的能工巧匠们纷纷效仿,制做出了形形色色的花钟,这里有俄罗斯花钟、日本花钟、北京花钟。这些花钟装点了城市,美化了生活。
2.师抓住“大致”一词,让学生读句子,体会到与前面写花开的时间范围词一样,也是语言的一种准确的表达。
3.提议大家一起来做一个花钟吧!同学们把自己搜集的资料快乐的一起编了一个新的花钟。
4.读练结合,建议学生们观察周围的花草并写成日记,为本单元习作埋下伏笔。

理解课文内容
1、朗读课文,学习运用多样的句式表达。
2、正确、流利、有感情地朗读课文。
3、读懂课文内容,初步培养学生留心观察周围事物的习惯。
在理解课文的基础上,理解不同的表达句式,并尝试使用。
多媒体课件
一、谈话导入:
1、初读了《花钟》一文,你了解到了什么?
2、小结:因为花开放的时间不同,有一位植物学家就利用它做了一个大自然的花钟,小朋友们你们想知道这个大自然的花钟是什么样子又是怎么做出来的吗?我们继续学习课文。
二、学习第三自然段:
1、多媒体课件出示花钟图片,生欣赏。
2、学生一边欣赏老师适时解释:只要看看什么花刚刚开放,就知道大致是几点钟,这太不可思议了。世界上最早发明、最著名的花钟是瑞士的日内瓦大花钟,它座落于瑞士这个花园之国。瑞士又称钟表之乡,瑞士的能工巧匠绝妙地将花卉之美同钟表的制造工艺完美地结合起来,
3、学生谈欣赏后的感受。
4、读文章第三段说说植物学家的做法妙在何处?
5、生汇报。
6、指导朗读,注意带着赞赏的语气读。

b、你认识它们么?来叫一叫他们的名字吧。(课件出示图片)
c、联系课文及图片理解“鲜花朵朵,争奇斗艳,芬芳迷人”
5、这么多花是什么时候开放的呢?请找出相关的句子来说一说
a、读这句描写花开放的句子。
b、出示句子进行比较。
c、带着独特的体验朗读本句:
(凌晨四点,牵牛花开了;五点左右,蔷薇开了;七点,睡莲开了;中午十二点左右,午时花开了;下午三点,万寿菊开了;傍晚六点,烟草花开了;月光花在七点左右开花;夜来香在晚上八点左右开花;昙花却在九点左右开放……)〈在比较中体验到课文用词的准确性,并理解“欣然怒放,含笑一现”的意思,训练学生对好词的积累〉
d、省略号告诉我们什么?想不想知道还有哪些花也会在整点开放呀?找到后,也用小作者的表达方式来描述一下花。句式说话:_____点,______花________。
6、真能干,一个个都简直成了小诗人了。各位小诗人,刚才我们通过认花、了解花是什么时候开放的以及用诗人般的言语描绘自已知道的花,现在,你们对花的感受不一样了吧!带上你独特的体验师生对读第一段。
7、读了这段课文,小朋友们又会很自然地发出哪些问题?

花钟温度湿度光照有趣
原因昆虫活动观察
九、教学反思
(一)、把“品味和发展语言”作为切入点。
要让学生在语文素养上得到实实在在的发展,提高课堂教学的“有效性”,本课的教学设计中,根据学生兴趣及文章特点,把“品味和发展语言”作为切入点。学习的重点放到第一自然段,设计了四大环节:
(1)、自读圈点,初步感悟;
(2)、比较句子,品味语言;
(3)、自悟自得,积累语言;
(4)、仿写延伸,发展语言。这些教学环节,既有前后关联,又有层次推进,层层内化地将学生引领进入“花钟”的奇妙世界之中,学习课文是如何借助语言对花开进行丰富精妙的表达的,体会汉语言文字的丰富,从而扎实学生语文功底,体现了语文学科特点。如,进行句子对比,学生通过听、读、辨,自己发现问题,发现了改过的句子是那样单调、枯燥乏味,激起了学生去寻求、去感受,去体验丰富、生动有趣的语言美的欲望,体现了新课标自主探究的精神。同样是写“花开了”,课文里却用了丰富多彩的语言表达方式,让学生真真切切地体会到语言的丰富和精妙。其间,学生对“吹起小喇叭”、“欣然怒放”的理解与感悟是那么独到又富有想象!这样的语言活动,培养、发展了学生的语言能力。
(二)、多媒体课件教学激发了学生学习的兴趣。
本节课恰如其分的情境布置、生动的多媒体课件,构成了轻松,愉悦的语文课堂,而这一切都应从课堂需要出发,从学生的心理需要出发,要让“现代化教学手段”直接指向语文学习。本节课上几处运用多媒体手段,如,各种鲜花的图片与文中的美言相结合,实现了图文并茂;接着将学生在第一课时后查找到的各种花儿的图片用于本节课的“语言再现”;出示花钟图进行欣赏。这样的教学设计,使课堂流露出一种自然的美,生趣盎然,而且与教材情境浑然一体,水乳的交融。
另外,本课教学中学生不仅利用课余时间查找资料、运用资料,更重要的是通过课堂反馈、评价、留作业等手段,意在增强学生收集信息、处理信息,运用信息帮助学习的能力,并使学生养成收集、查找资料的习惯。
(三)、给学生提供“自由的学习空间”。
本课的学习中,学生能够“读一读讲一讲”、“说一说背一背”、“交流归纳”、“介绍资料并仿写”,可以根据兴趣爱好自由选择“喜欢哪句就说哪句”;可以在想象的召唤下,转换角色变成小喇叭;可以身临其境徜徉在百花园中观看花儿绽放的美姿;还可以通过朗读的表现力来抒发自己的情感……老师在课堂中是引导者、倾听者、合作者。学生们在合作学习,研究探讨中,体验了学的过程,实现了教材的开放,课堂的开放,获得了自由的学习空间。
当然,本节课也有一些不足之处,第一段是重点,没有把握好时间,在训练学生说话时,未能让更多的学生参与其中,在第二段教学时显得有些仓促,因此,结尾草草收兵。在今后的教学中学会更好的把握课堂,提高课堂驾驭能力。

花钟教学设计一等奖篇十三
《语文课程标准》指出:“语文课程应积极倡导自主、合作、探究的学习方式,语文课程应该是开放而有活力的。”本课以建构主义理论为依据,构建信息环境下“主体参与”教学模式。设计以学生原有知识经验为基础,利用虚拟网络,为学生提供多样化学习资源,创设生动有趣的自主学习环境,引导学生在合作中积极、主动参与学习,真正成为学习的主人。
根据义务教育课程标准实验教科书语文三年级上册第13课《花钟》这篇课文所引发的植物学家利用花开放时间的不同,制成“时钟”,可是“为什么不同的花开放的时间不同”呢?因为由此入手,带领学生就这专题进行研究型学习。环境下的问题探究学习使本课有了丰富的外延,主要学科是语文,还涉及到历史、地理、美术、环保、社会、自然等方面的学科知识。在教学中推崇创造性学习,让学生在开放的课堂快快乐乐地获取新知,从而品尝到成功的乐趣。

2、 揭谜底:钟(板书)
3、 给“钟”字组词。(生回答)
“花钟”(课件出示或师板书)
4、 读词质疑:读了这个词语,你最想知道什么?你想说点什么?(生回答)
5、 这些问题的答案也许都在课文中藏着呢。今天我们就一起走进《花钟》这篇课文,一起
去揭示其中的奥秘吧!
二、 学习生字、词语。
1、 师引出生字的学习。
2、 出示生字卡片,以全班读、开小火车读两种形式检查学生预习生字的情况。
3、 (课件出示词语)全班齐读。
4、 师重点强调:

(4)(课件出示)昙花却在九点左右含笑一现……
从这句话中我们可以了解到昙花开花的特点(晚上开。开花的时间很短,没多久就凋谢了,所以有一个成语叫做-----昙花一现(板书)
4、课文中像这样美的句子还有很多,你还认为哪些句子写得美,找出来我们大家一起来分享。(生自由交流朗读)
5、 师小结:
(1) 刚才我们看了作者笔下的这些花,它们各有各的长相,各有各的姿态,各有各的性
情。看来,写花的开放不止一种说法,用不同的说法表达同一个意思,这篇课文就给同学们做了一个很好的示范。同学们以后在写作文的时候就可以学习课文中的这种写法。要想把文章写得美,积累很重要。同学们可以将这些好词妙句抄到积累本上,相信同学们一定会有很大收获的。
(2) 作者把这些花描写得那么美,说明作者对这些花充满了——(喜爱之情)他非常热
爱大自然,留心观察身边的事物。让我们一起带着喜爱、赞赏之情再来读读第一自然段。(师生引读)
(3) 拓展练习:我们也来赞美大自然中的花。(课件出示) 金秋十月, 菊 花 在秋风里昂首怒放。
七、 总结作业
1、 通过这节课的学习,我们知道了不同的花开放的时间是不同的,这种现象是如何产生的
呢?我们下节课再一起来探讨。
2、 作业:抄写生字、词语。
一、复习导入
1、上节课我们学习了什么内容?通过学习你有什么收获?
2、生交流汇报。
二、细读探究
过度:大自然是一位奇妙的造物主,不同的花能够按时开放,这样的现象是如何产生的呢?这节课我们就来探索其中的秘密吧。
1、讲读第二自然段
(1)生默读第二自然段,画出表示不同植物开花时间不同的原因的词语或句子。(生默读,师巡视)
(2)不同的植物开花时间不同的原因是什么?(师根据生的回答归纳板书:温度、湿度、光照、昆虫活动的时间)
(3)昙花开花时间和温度、湿度、光照有什么关系?同桌之间互相说说。
(4)课文中还有哪些词你不理解?
适宜:合适、相宜。
吻合:完全符合。
2、讲读第三自然段
(1) 前面同学们提出了一些问题:什么叫花钟?花钟真的能够报时吗?这些问题的答案
同学们都找到了吗?下面我们就来学习第三自然段,答案也许就在里边。
(2) 生齐读第三自然段。
(3) 什么叫“花钟”?(指名回答)
同学们见过花钟吗?老师这儿收集了几张花钟的图片,大家一起来欣赏一下。(课件出示花钟图片)
(4)“这些花在二十四小时之内陆续开放。”“陆续”什么意思?(表示前后连续不断) 你能用“陆续”说一句话吗?
(4) 比一比:①你只要看到什么花开放就知道是几点钟。
②你只要看看什么花刚刚开放,就知道大致是几点钟。(生齐读) 这两句话有什么不同?(生回答)
是的,“刚刚”和“大致”这两个词是不能去掉的,去掉后意思就不准确了。
(6)全班齐读第三自然段
三、总结作业
1、通过这两节课的学习,我们知道了不同的花开放的时间是不同的,不同的植物开花时间与温度、湿度、光照、昆虫活动的时间密切相关。正是因为善于留心观察身边的事物,认真思考,植物学家才突发奇想地修建了“花钟”,这真的是很有趣。
在日常生活中,只要你留心观察身边的事物,认真思考,做生活的有心人,你也会有许多发现。
2、作业:观察你最感兴趣、最想写的一样事物,把它写到日记里。

8、 读了课文你还知道些什么?(交流)出示填空:我知道
9、 你认为课文哪部分让你很感兴趣?
如:学生选择第一自然段。
1、用自己喜欢的方式读读这一段。
2、谁想用朗读来表达自己的喜爱之情?(请学生朗读)师:你读出了自己的感情,老师都被你感动了。你为什么会如此钟情于这一段呢?(说体会,谈感想)
3、 用课件出示两段话,学生朗读进行比较。(一段是原文;一段是教师改编,描写花儿开放的句式单调、干巴。)为什么你喜欢原文?(说理由)
4、 师生合作朗读本段课文。
5、 交流自己的收获。
6、 带着自己的体验与感受再美美地朗读这段课文。
7、背诵喜欢部分,与同学交流。

培养学生留心观察周围事物的习惯。
2课时
第一课时
一、创设情境,激趣导入
1、走入花的世界,欣赏鲜花,感受鲜花的芬芳迷人。
(学生自由谈感想)
2、这么多的花争着开放来比美真是繁花似锦,美不胜收呀!知道么,这么美的花儿身上还蕴藏着许多奥秘呢!今天就让我们来学习一篇有关于花的文章(板书课题)读课题,提问题。
【预设问题:花钟是什么?为什么起名字叫花钟?花为什么能做钟呢?花和钟怎么联系在一起,花怎么成为花钟呢?同学们读书有疑问很好,在心里记下你的问题,到课文中去寻找答案吧!学生自读课文。】
二、检查预习,掌握字词
1、出示:芬芳、凌晨、苏醒、干燥、灼伤、适宜、淡雅、吻合、组成、修建、昆虫、展示
指生读,有不理解的词语吗?生生释疑
师出示:吻合:1、合拢。2、比喻两相符合;一致。
2、书写重点讲解:
凌:右半部分的上边是“土”
建:笔顺先里后外
三、初读课文,整体感知
1、提出初读要求:选择自己最喜欢的方式读课文,要求:读准字音,遇到生
遇到难读的地方多读几遍。
2、指名读句子〖puxuewang、com〗,注意读准生字。
(出示含有生字的句子)
(1)下午三点,万寿菊欣然怒放;傍晚六点,烟草花在暮色中苏醒。
(2)昙花的花瓣又大又娇嫩,白天阳光强,空气干燥,要是在白天开花,就有被灼伤的危险。
(3)还有的花,需要昆虫传播花粉,才能结出种子,它们开花的时间往往跟昆虫活动的时间相吻合。
(4)长期以来,它适应了晚上九点左右的温度和湿度,到了那时,便悄悄绽开淡雅的花蕾。
(5)你只要看看什么花刚刚开放,就知道大致是几点钟。
3、交流“什么是花钟?”“为什么花可以做钟?”从课文中找到相关的句子读一读。
“一位植物学家曾有意把不同时间开放的花种在一起,把花圃修建得像钟一样,组成花的‘时钟’,你只要看看什么花刚刚开放,就知道大致是几点钟。”
教师播放花钟的课件教师指着大屏幕说:这圆圆的花圃上,鲜花朵朵,陆续开放,就在告诉我们时间,这就是花钟,你觉得这是一座怎样的时钟?
【设计意图:学生用简练的话表达自己的感受,锻炼学生的概括能力,为后面的概括段意铺垫。】
四、默读课文练习概括
1、顺着学生的回答:美妙的花钟、神奇的花钟、令人心旷神怡的花钟,教师提出要求:默读课文,课文每段介绍了什么?可借助泡泡里面的问题来回答。
2、指生答
3、有什么发现吗?
有的文章开头第一句能概括该段的大意,这叫做给“关键句”,也叫“中心句”。

2、出示本课生词,分类读一读,用其中的几个词说一句话。
二、整体感知:
动漫读文,学生思考:你了解到了什么?
三、品读感悟交流体验
(一)学习第一自然段:
1、指名读,这段给我们介绍了一种有趣的现象,是什么现象呢?(不同的花开放的时间是不同的。)
整个这一自然段都是围绕这句话来写的,因此这句话就是这一段的(中心句)指导学生用“———”勾出来,围绕它作者介绍了哪几种花?
2、老师复述:凌晨四点牵牛花开了……开了……开了。
刚才,我们一起欣赏了这些美丽的花,那你们有没有注意到老师说些什么?我们把刚才说的连起来就是:
(出示句子,凌晨四点,牵牛花开了;五点左右,艳丽的蔷薇开了……)
请同学们仔细看,你发现老师把这些花开的情景形容的好不好?(学生总结老师形容的不好,原因是“开了”一词用得太多,过于单调、干巴,一点也不美。)
3、读读说说:同样是写什么花在什么时候开放,书上是怎么写的?请再读一读第一段中的相关句子,并选一句自己最喜欢的,反复读,和同桌说说你想像花开时的情景并说说喜欢的原因。
4、学生自读,互读,感悟。理解课文是采用了拟人的手法,使得文章生动形象。

更 。
7、想想作者是怎么知道这些花几点开放的?为什么其他人没有发现?对你有什么启示?(作者是经过仔细认真而且长期的观察才知道这些花的开放时间的。)
(二)学习第二自然段(以自主合作学习方式为主)
1、不同的鲜花为什么会在不同的时间开放?这个问题课文中回答了没有?(课文中立即回答了这个问题。这种自己提问自己回答的句式叫做设问句。)
2、默读课文第二自然段,画出表示植物开花时间不同的原因的句子。
3、交流并朗读“植物开花的时间,与……有着密切的关系”和“还有的花,需要昆虫传播花粉,……”等句子。
4、哪位同学能举例说明植物开花的时间与温度、湿度、光照有很大关系呢?
(以昙花为例进行讲解,引导学生明白举例子的说明方法。)
“吻合”是什么意思?哪位同学能举例说明有些植物开花的时间与昆虫的活动相吻合?(牵牛花)
5、集体交流,老师相机点拨并板书:温度湿度光照昆虫活动 。
(三)学习第三自然段
1、默读,思考:花钟有什么作用?结合回答,出示“大致”一句,想一想:花钟能提醒我7:38分收看《焦点访谈》吗?为什么?
2、出示句子: “我看到什么花开了,就知道是几点了”这句话对吗?
文中用语言怎么叙述的?指名读第三自然段。
出示句子:齐读“你只要看看什么花刚刚开放,就知道大致是几点钟”
两组句子有什么不同?“刚刚”可以去掉吗?为什么?“大致”还可以换成什么词?
3、是啊,作者用词非常准确,这个词语反映了客观事物真实的状况,反映了科学家遵循客观事实的态度,文中还有几个这样的词语,请大家快速浏览全文找一找。
板书词语:大概 左右 往往 有……的危险
4、体会朗读第三段。
四、再读全文,总结拓展
1、感情朗读全文,找出你喜欢的好词佳句
2、你知道世界上第一个设计花钟的人是谁吗 ?(瑞典人林奈)
他为什么能设计出如此有趣的花钟?
3、激发情感:林奈之所以能设计出这么有趣的花钟,是他留心观察,不断探索的结果。我们也要养成留心观察事物的好习惯,发现探索美丽的大自然。如果我们也有一双像林奈一样善于发现的眼睛,相信你一定会发现许多奥秘。从今天起,就让我们多写一些观察日记吧!
4、你能说说在日常生活中你观察过什么?有什么发现?
花钟教学设计一等奖篇二十五
《花钟》是人教版小学语文第五册第四组紧扣细心观察这个专题的一篇文章,课文按照“归纳现象—揭示原因—实际运用”的思路,说明不同的花会在不同的时间开放及其原因。作者先讲观察后的发现:一天之内,不同的花开放时间是不同的。并形象例举了牵牛花等9种花不同的开花时间来说明这个发现;接着分析回答了不同的植物开花时间不同的两个原因:开花时间与温度、湿度、光照有关,与昆虫的活动时间有关;最后扩展开去,谈到植物学家修建“花钟”,其做法很奇妙。
学生基础较好,进入三年级,有了比较强的学习能力和比较丰富的语言积累,对大自然充满了好奇。
针对学生实际和教材特点,我将第二课时教学目标定位在:
1、正确、流利、有感情地朗读课文,理解“舒展、欣然怒放、大致”等词语的意思。背诵自己喜欢的部分。
2.读懂课文内容,初步培养学生留心观察周围事物的习惯。
3.学习运用多样的句式表达。
在理解课文内容的基础上,理解不同的表达句式,对一些句子尝试换一种说法是教学的重点。
基于教学目标的制定和重难点的提出,结合《新课标》理念,让学生在主动积极的思维和情感活动中,加深理解和体验,有所感悟和思考,受到情感的熏陶。努力构建开放而有活力的新型语文课堂,始终体现学生是学习的主人,教师是学生学习的伙伴。通过自主、合作、探究的体验性小组合作学习方式,读中感悟、读中体验,采用“激趣——发现——感悟——实践”的思路,引导学生在自主中学习本文。
我主要采用不同形式,不同要求的读,引导学生感受课文的语言美;读中感悟、读中发现、读中理解,利用多媒体课件,让学生欣赏千姿百态的花,发现鲜花的奥秘,体会大自然的神奇美妙,组织学生小组讨论,合作探究,动手实践,解决教学重难点。
整个教学过程,我是分五个环节进行设计的:
(一)欣赏鲜花,悄然入情
为了达到“课伊始,趣亦生”的目的,我用多媒体课件制作了精美的鲜花画面,并配上美妙的音乐,带着学生去赏花。欣赏后,让学生用积累的词语描绘刚刚看到的鲜花。随后,课件出示课文中的句子:(鲜花朵朵,争奇斗艳,芬芳迷人)再让学生美美地读一读这一句,感受鲜花的美丽迷人。由此切入课题:这些鲜花不但漂亮迷人,在他们身上还藏着许多有趣的秘密呢!这节课我们继续走进第13课《花钟》。
如此激情导入新课,学生的听觉,视觉,思维,想象,多频道运作,情绪一下子被调动起来了。教学也因为学生的入情,而进入积极的状态。
(二)自由读文,发现秘密
因为第一课时学生把课文读得比较熟练了,我直奔主题:再一次自由读文,边读边想:读了课文之后,你发现了花的哪些秘密?学生交流自己的发现后,我归纳学生的发现:一天之内,不同的花开花的时间是不一样的。并适时播放课件(九个时段的九种花),引读描写的九种花开的九句话。
(三)归纳现象,品味美文,写作训练
第一段语言很美。作者用不同的方式来表达鲜花的开放,并抓住鲜花的形态特征巧妙地来描写。我让学生把朗读、理解、感悟紧密结合起来。先自由朗读这句话,边读边做动作,看看说就像这些盛开的花朵。有的学生吹起了小喇叭,有的学生则绽开了自己甜甜的笑脸,也有的学生在舒展自己的筋骨,这时我结合课件相机来学习这几句话理解“欣然怒放”“舒展”等词语,欣赏各种花开的样子,然后一起美美的品味文意。
在理解课文内容的基础上,理解不同的表达句式,对一些句子尝试换一种说法是教学的重点,为了突破这个重点,体会不同的句式表达的效果中,增强语言感悟能力,并引导学生在后面的学习中能够迁移运用。我设计了一个比较题:李老师也写了一些这些花开的句子,你们读一读,和书上的比一比,看看我写得好不好?这时课件出示我写的句子,我把句子全换成“午时花开花了”,“夜来香在晚上八点开花”这样的方式。学生读起来觉得枯燥、单调,从比较中的得出:同样是写花开,作者抓着了花的形态特征,用不同的方式来表达,很巧妙。比较之后,顺势进行小练笔:你还知道哪些花在什么时候开放?
能不能像作者一样来写一写呢?用“——点,——花————————。”进行练笔。
(四)小组合作,揭示原因
课文第二段是归纳原因,我采取了小组合作学习的方法。
大自然真是奇妙!为什么不同的花开放的时间不一样呢?我们通过小组合作学习第二段来解决吧!先来看看小组合作学习单:
小组合作学习单
1、读一读
用自己租喜欢的方式读一读第二段。
2、议一议
在小组里讨论讨论:为什么不同的花开放的时间不同?
3、填一填:造成不同的值五开花的时间不同的原因是:
(1)植物开花的时间,与()、()、()有着密切的关系。
(2)还有的花,需要()传播花粉才能结出种子,因此与()有关。
4、说一说
昙花为什么会在九点含笑一现?用自己的话说一说。
小组学习之前有要求和目标,学习之后有相应的检测,这样的小学学习就真正达到了“合作探究”的效果。
(五)实践运用拓展延伸
学生发现了鲜花的秘密,了解了其中的原因,该实践运用了。我通过多媒体课件介绍世界上最早、最著名的“日内瓦大花钟”再次激发学生的兴趣,引导学生自由朗读第三段,并想一想:这种做法有什么妙处?
在教学第三段时,我抓住“大致”一词展开教学让学生明白“语也是一种准确的表达,是对客观事物真实状况的准确反映。无论开花时间,还是原因的分析,都是在一定有范围、有一定的条件限制的,把话说死了,看似肯定,反而不科学了。最后,我建议我们师生在课堂上试着做一个花钟,掀起了这节课的又一高潮。师生合作做好花钟后,有些指针上是空白的,正好是延伸拓展课堂的机会。我差了很多资料,都没有找到在两点钟开放的花,还有些指针该用什么样的花来表示呢?需要同学们到课外和大自然去寻找,激发学生发现大自然的兴趣。

钟(图)
有趣
板书设计是微型的教案,我用抓重点词语的方法,设计了新颖的板书,“花钟”两个字是写在课堂上作的两面花钟的中心。起到了画龙点睛的作用。
总之,这节课我抓住以上几点教学设计,通过“自主、合作、探究”的学习方式,以读为本,让学生在读中感悟,读中发现,读中体会,学会了合作,积累迁移,并进行小练笔,比较好地体现了语文学科工具性与人文性的统一。
