大象版小学科学说课稿 苏教版小学科学说课稿篇一
今天,我说课的课题是小学科学教科版五年级上册第二单元《 光 》第 3 课时。下面我将从教材分析、教学理念、教法学法、教学过程等四个部分进行说课。
在本课内容之前学生探究了光和影的关系,建立了一些感性的认识。在这一基础上再研究光是怎样传播的。我认为编者的意图是让学生巩固光和影子的科学关系,又为后续学光在传播途中碰到障碍物会怎样的研究打下基础,使学生的动手能力、思维能力、创新能力、探究精神得到全面的发展。
这一课的内容分二大部分。第一部分是“光是怎样照到物体上的”;第二部分是“验证光的传播路线”。
五年级学生的已经有一定的科学素养,同时对实验课兴趣非常浓厚。但是在思维上,逻辑性、严谨性不强,考虑问题不周全,实验操作,对学生而言都是很好的锻炼。本节课无论是实验设计还是实证光是直线传播的探究活动,强调让学生在教师的指导下通过亲身经历、发现、探究、推测、验证的科学探究过程,发展学生对科学的理解力,思维力及多方面的素养。
根据“科学课以培养小学生科学素养为宗旨,积极倡导让学生亲身经历以探究为主的学习活动”的课程理念结合学生的实际情况。
我将确定以下教学目标:
1、科学概念:光是直线传播的。
2、过程与方法:有依据地推测光的传播路径;设计验证光是直线传播的实验;利用光的传播规律解释为什么会有影子。
3、情感、态度、价值观:培养学生爱思考的习惯,以及善于思考的能力;知道推测要有依据;在实验中能认真观察、勤于思考,根据实验结果实事求是地进行分析、推理。
本课教学的重点是通过实验验证光是直线传播的。
难点:寻找假设的依据说明光是直线传播的。
教具准备:手电筒、3张在同一位置打孔的长方形卡纸、屏、空心管和直管。

有人将科学比喻为引导学生过河,教师在教学过程中,必须运用好的教学策略,为学生提供“过河”的下脚石,但又不能越过这个度,教师只作启发式点拨,引导学生自主探究。根据《新课程标准》以“培养学生的科学素养”为宗旨,及结合学生的实际情况,我将本课的教学法确定如下:
从教的方面来说,本课主要采用“引导—发现—探究”的教学方法。学生是学习的主体,让每位学生都能像科学家那样研究科学,从而让学生学到探究科学规律的本领。本课通过让学生对光是沿着直线传播的实验观察、研讨、推测、验证、解释。为了能使教学目标得以落实,取得良好的教学效果,本课中我还同时综合运用了(讨论法、实验法、探究——研讨法等)多种教学方法来组织课堂教学
从学的方面来说,本课主要采用(观察法、探究实验法、小组合作、自主探究法等)多种学习方法,指导学生通过多种感官对光传播的现象进行有意识的初步认识,充分发挥学生的创造力,使学生能独立进行探究实验,能充分发挥手、脑、眼的功能,从而获取新知识,培养技能技巧。从小组合作中培养学生的合作意识和探究意识,使他们乐于交流,并善于发表自己的意见。
我的教学设计是以“探究、开放、自主、合作”为基本指导思想的。下面是我对这节课的教学设计的说明。
(一)、创设情境,提出问题
活动一
创设情境,引导学生观察日常生活中光照的现象(出示图片及课件)
清晨,太阳出来,房间洒满了阳光;黑夜,打开手电筒,灯光照亮了前面的路;在观察中提出问题。这些光是怎样到达被光照的物体上的?组织学生进行讨论、猜测,激发学生利用实验获得证据,证明自己的观点是否正确。
创设这样的问题情境引入,使学生的思维产生强烈的碰撞,这一锤就敲到了学生的心坎上,充分激发了学生的探究欲望,可以很快使学生积极思维,进入科学探究的活动中来,达到了预期的教学目的。
(二)组织探究,得出结论。 (重点)需修改
活动二
出示有结构的材料,组织学生讨论实验的方法,猜测实验的结果。因为教科书上学生操作的验证实验,器材简单,操作容易,可以放手让学生自行合作制定实验方法和步骤,自行操作,但要求实事求是的记录实验结果,在图中的卡纸上直接用箭头标出光前进的路线。在过程与方法中推测依据很重要。通过实验得出小孔在一条直线上,手电筒的光就能到达最后的屏上,形成小斑点。否则就不会有此结果。
在这一环节的活动中,先让学生自主合作、大胆猜测光的传播是否沿着直线的方式进行的问题产生认知的矛盾,也就有了探究、验证的需求。这时,教师让学生进行验证也就水到渠成了。同时学生的小组合作学习在这个环节中所起到的作用也是科学、有效的。小组活动中,同学们在小组长的安排下,有的到实验材料区去选取实验所需的材料,有的负责记录,有不同的看法互相交流,然后小组长把全组的意见整理、汇报,得出了“光是直线传播”这一结论。这符合学生的认知规律,又充分的体现新课程自主探究的精神。
(三)扩展探究,培养热情
接着激发学生用其他的方法也来验证光的传播路线,可以是直管和弯管的对比观察,直管眼睛就能看到另一头的光,弯管就不能,进一步证明光是直线传播的。同时提醒学生不要用眼睛只对很亮的光源。还要给学生留个思考的空间,说说还有哪些方法验证光的直线传播。再利用光是直线传播的理论解释影子总是在光的背面的道理。为了更有效知识延伸,还可以用课件图片出示,光的传播速度以太阳为例,进一步扩展了学生的探究活动,使学生所形成的概念得以巩固。令科学知识从书本走向实践,由课堂走向社会。
(四)、板书设计
为了紧扣教学目标,突出教学重点,我用简洁明了的词语进行板书,概况了本节课的主要内容,让学生一目了然,让对所学知识留下深刻的印象。

记录一天的食物一天的食物给食物分类回忆并记录自己早中晚餐所吃的食物快速认识众多食物的一种方法
教材从记录一天中吃过的食物开始,并让学生把食物一样一样分解开来。当几十种食物呈现在学生面前时,怎么去观察研究呢?这就自然而然地进入到第二个活动,给食物分类。 给食物分类,方法很多。希望学生根据自己的生活经验说出不同的分类方法,可以是按“味道”分,可以按“是否喜欢”分,可以按“早中晚餐”分,这些方法虽然可以,但都较为主观的,分类的结果因人而异。教材希望学生通过比较分析,得出科学的分类方法:如按人们的生活习惯,可以把食物分成粮食、蔬菜、水果、调味品等;根据食物的来源,可分为来源于植物的食物(素食)和来源于动物的食物(荤食)。教材中的素食和荤食的两幅插图,可以使孩子们直观地了解这两类食物的区别,有助于孩子们进行分组讨论,进一步了解荤食和素食的主要种类,使孩子们对食物分类的研究更加深入。
这堂课我主要想以孩子们一天当中吃的食物为载体,让学生体会科学就发生在自己身边,与自己的学习、生活息息相关,孩子们为了认识和解释这些内容,也要像科学家一样,通过观察和实验,亲身经历,亲身体验一系列的科学探究活动,从而使学生们关注自己的日常生活,关注身边的科学,使他们不断深入到科学的探究过程之中,提高自己的科学素养。
1、课前谈话。通过课前 “猜”这种游戏式谈话拉进师生情感距离,放松心情,同时让学生明确本节课努力的方向。
2、说一说自己的收获。在这个过程中,首先是请学生欣赏食物图片,这样可以让学生通过对食物直接、形象地目视交流,打下一步探究食物的兴趣基础。接着让学生谈了谈自己初步观察、收集资料之后的收获,学生对自己的经历都有了做一个小结式的认识,还能交流记录过程中发现的问题,同时促使学生在经历活动的过程中养成思考的习惯。
3、、动一动:给一天的食物分一分类。
在这个过程中我试图让学生从一种无认识的状态逐渐摸索、实践到一种形成认识的状态。首先让学生去玩两个活动,活动的目的是关注学生寻找、收集、整理信息和证据的能力,并以此推动学生去进行归纳、分析、逻辑推理。同时让学生自选标准给食物分类,目的在于调动他们已有的认识储备,通过分类进一步认识食物,知道食物的种类很多。
在汇报分类情况时,各组也只要说出分类的依据,分类结果只要合理都予以肯定。就这样通过实践、交流、实践、交流螺旋上升式的教学,让学生不仅了解了食物的丰富性,还让学生学会了能够用多种方法对食物进行分类。最后通过情景认识,实物操练,让学生对人们常用的“荤、素”这种分类方法有较深的认识。最后是,想一想:有什么收获?还想研究什么?
通过学生这种自我反省式认识,进一步引导学生对过程的回顾,对食物的探究,提升了学生学习总结的能力,培养了学生的质疑精神,为本单元下一步教学作了很好的铺垫。

1、教材简析
《天气预报》是大象版小学五年级下册第二单元第四课。
天气是与人类的日常生产和生活密切相关的现象,其对我们的影响日益增加并越来越受到重视,儿童从小就对气象产生浓厚的兴趣,对于他们来说有很多知识需要探索。
本节课的主要资料包括有:明白天气变化的自然现象;了解天气预报的制作过程;搜集天气预报的有关知识;学会制作科技小报等知识。
让学生利用科技小报进行表达与交流,让学生充分展示自我的成果;宣传科技知识;巩固学到的知识同时锻炼学生收集资料,设计制作等本事。
2、学习目标
(1)明白天气预报的流程。
(2)了解预报天气的常用简单方法,能坚持开展长期的天气预报活动。
(3)能制作气象小报。
3、教学重点难点
重点:了解天气预报的常识。
难点:制作科普小报。
农村小学五年级的学生对天气现象并不是很陌生,尤其是对下雨前的自然现象有很多的了解,课文中这一资料完全能够让学生自我讨论交流就能够完成的,但对天气预报的制作流程不是很了解,教师在这个资料上就要利用有关的图片视频资料帮忙学生去了解。制作科技小报其目的是让学生去收集资料,农村学生受条件的限制,可能在收集资料上有局限性,这就要求学生的小报资料不限,形式多样。
根据《新课程标准》以“培养学生的科学素养”为宗旨,结合学生的情景我采取的方法是;“交流----探究-----讨论------交流”的方法,经过让学生经过对天气变化前的自然现象进行交流了解一些天气变化前的自然现象,然后经过教师的讲解和查阅资料看图片、视频去了解天气预报的制作流程,同时还要了解一些天气预报新的资料——气象指数,教师要指导学生怎样进行长期的气象观测,培养学生长期观察的习惯。在制作科技小报的时候能够要求同学们结合当地的实际情景,充分利用当地的一些气象谚语和农民长期总结的一些气象知识来制作。
本课的教学过程主要分三部分完成。
第一部分阅读与交流:首先让学生阅读“下雨了”连环画了解动物与天气变化的关系,然后让学生交流讨论你们还明白那些与天气变化有关系的自然现象(这个资料对农村孩子并不困难,能够让学生归纳在一齐互相交流,让大家了解更多)
第二部分探究讨论:教师首先准备了有关天气预报制作流程的图片和视频(制作成演示文稿)。教师能够借助图片和视频让学生更深的了解现代科技与天气预报的关系,了解有很多很多的科技工作者为天气预报付出了辛勤的劳动,同时还要对学生进行长期天气观察,测量,搜集气象谚语,收听天气预报的习惯的培养(收听天气预报方法有:查询电话12121或96121;看电视、报纸、和互联网)。此外为了让学生掌握更多的知识我还利用幻灯片让学生了解天气预报增添的一项新的资料——气象指数预报。这样学生不仅仅了解了天气预报的制作流程同时也了解了更多的新知识,这样更加激发他们去长期观察天气。
第三部分:制作科技小报{讨论交流},经过交流探讨同学们已经了解了很多有关天气预报的知识,这时能够让同学们把你们明白的有关天气预报知识分资料写出来,在全班上交流相互取长补短,学生已经掌握了很多知识性的东西就能够开始办科技小报了,这时候教师能够出示教师自我办的一份小报作示范,同学们能够仿照我的格式或方法,当然要要求学生不能千篇一律要形式多样,资料丰富,板式新颖漂亮。学生可能一时不能完成就布置在下一节课进行展出。
这一课的练习分为长期练习和当堂练习。
长期练习是:坚持长期的气象观测并做好观测记录,每月进行整理分析数据一次。
当堂练习是:修改科技小报(在修改过程中能培养学生收集知识本事和动手的本事,当堂不能完成能够课外完成。
本课的设计方案我以往在我校两届五年级班进行了教学,效果很好,异常是学生办的科技小报很有特色,有电子版的,有手写版的,都是图文并茂资料丰富,有必须的科学性。学生在办科技小报的同时收集和积累很多的科技小常识。学生对天气的观察记录的兴趣也培养起来了,大多数同学能坚持观察天气并记录分析和整理,同学们自我成立了一个气象小组,不定期的在班上发布气象信息,编制气象小报,效果十分好。 授之以鱼不如授之以渔,在这节课中我充分利用学生感兴趣的东西让学生自我去交流----探究-----讨论------交流,从而得到新的知识,这种方法比教师去讲解要好得多,这样不仅仅让学生学到了知识,更重要的是掌握了获得知识的方法,这才是教师要学生真正掌握的技能。
1、用气象符号记录一周的天气情景。
2、搜集有关天气的谚语。
3、搜集动物、植物预报天气的资料。

能够如实的描述土壤中的动植物,尊重事实,养成实事求是的意识;
学会倾听,愿意分享,乐于表达,小组间做到团结合作。
4.科学、技术、社会与环境目标:
能够意识到人与自然是和谐的整体,密不可分。
教学重点:通过观察和认识,让学生意识到许多动植物依赖土壤生存或生活。
教学难点:通过观察理解让学生意识到人与自然是和谐的整体,密不可分。
土壤、水槽(放土壤的容器)、放大镜、镊子、铲子、记录表等。
第一课时
(一)创设情境,谈话引入。
出示土壤的图片
土壤是一种我们既熟悉又陌生的事物,熟悉的'是每天我们都能看见,在路上、在院里、在校园的角落。而陌生在于即便我们经常看到,但很少有人蹲下身来仔细的观察过土壤。所以这节课,我们就一起来观察土壤以及土壤中的动植物。(出示课题)
(设计意图:让学生真正意识到土壤随然在我们身边,但大多没有仔细观察过土壤的世界,调动学生观察土壤的兴趣)
(二)观察土壤。
1.每组拿出事先准备好的土壤。
土壤中都有什么如何进行观察如何运用这些工具在观察的过程中我们需要注意什么问题
(设计意图:带着问题去观察,有针对性的做实验,能够达到意想不到的效果)
生1:土壤中可能会有小生物和一些枯叶子
生2:观察要仔细认真,有顺序,细致到每一个角落
生3:放大镜是放大一些小东西的,镊子用来夹物体,铲子用来铲土,观察土壤里的动植物
生4:在观察中要认真仔细,不漏掉每一个角落,要按一定的顺序,不要伤害土壤里的小生物
(设计意图:让学生猜测土壤中有什么,从而激发去挖掘的欲望,并让学生能够再说的过程中,组织好自己的语言,能够清楚的表达自己的观点,说明自己的的想法)
出示注意事项做补充。
2.观察土壤并做好记录。
(设计意图:边观察边记录让学生及时留下观察后的证据,做汇报时有据可依)
3.汇报自己的观察结果。
第二课时
(三)研讨活动。
1.我们发现了多少种依靠土壤生长和生活的植物和动物
(设计意图:在相同的时间内,小组之间发现的种数可能会有所不同,认真仔细有序全面的小组会发现的比一般小组多一些,可以形成组间竞争,激发学生观察的热情)
2.描述周围的土壤上生长着的植物和生活着的动物。
(设计意图:让学生体会到动植物和土壤的“关联”的认识,即帮助学生进一步强化认识,很多动植物都需要依赖土壤而生存)
(四)拓展。
用防水胶、木条、有机玻璃做一个扁的透明观察盒,往观察盒里倒满土并注意保持土的湿润。把蚯蚓或是蚂蚁放到土上,再铺一些嫩草和树叶,观察蚯蚓或蚂蚁的活动。
(设计意图:拓展活动有效弥补了学生不易观察到的土壤下的动物生活情况。不同地区可以考虑“蚂蚁工坊”这一材料替换,但观察蚯蚓从观察环境的真实性和观察成本来看都更为适宜。)
大象版小学科学说课稿 苏教版小学科学说课稿篇九
小学科学课程是以培养学生科学素养为宗旨的科学启蒙课程,是一门应用学科,它积极倡导让学生亲生经历以探究为主的学习活动,培养他们的好奇心和求知欲,发展他们对科学本质的理解使他们学会探究解决问题的策略,并乐于与人合作、与环境和谐相处。在这些理念的指导下,我设计了《听听声音》这一课。
本课的主要内容是通过引导学生有意识的倾听,让学生感受到我们是生活在一个有声的世界里,通过一系列的活动去体会声源与声音的关系。通过分辨声音的变化的活动,为未来建立有关声音的一些科学概念打下感性的基础。
结合教学内容及四年级学生的认知特点,我制定了本节课的教学目标,重在引导学生用心去倾听、分辨不同物体发出的声音,让他们以关注的态度在充分感知声音的活动中,学会对各种不同的声音加以简单的区分和鉴别,对声音的大小、高低、远近、方向加以适当地了解。通过对声音的研究,发展学生对声音进行探索的兴趣。
在具体的教学设计方面,我作了如下的构思和尝试:
《科学课程标准》指出“探究能力的形成依赖于学生的学习和探究活动”,因此在教学中必须结合科学知识的学习,创设情境,通过动手动脑、亲自实践,在感知、体验的基础上,内化形成。本课的引入,我就创设了这样的情境:我把全班分为a 、b两组,分别向左 、右转,背向而坐。请a组一学生讲:“猜猜我是谁”,b组的同学在不回头看的情况下,猜出是谁讲的。然后b组一同学讲,a组猜。在教师的引导下,随着这个简单、巧妙的活动展开,孩子们的学习热情充分的调动了起来,同时也在活动中沟通了教师和学生、学生和学生之间的情感,为40分钟的课堂教学创设了和谐的气氛。
这节课,我设计了三个活动:倾听和感受声音、听听固体、液体、气体发出的声音、分辨声音的变化。其中第二个活动就要求学生们能自主探究不同物体能发出不同的声音,为了使学生自主探究的活动充分得以实施。我为学生提供了多种有结构的材料,发生罐、水槽、刻度杯、筷子、铃铛、玻璃瓶、纸、舞板。由于活动材料准备得十分充分,从而为学生们的探究活动提供了方便。材料的多样性符合了不同学生的要求,尊重了学生的个性,开发了学生的思维。如在探究液体发声的过程中,学生即想到了用刻度杯倒水有想到了用筷子划水。
新《课标》提倡,学生是科学学习的主体,科学学习要以探究为核心。也就是说科学课应该注重学生的经历、体验和发现,在科学课上应该体现自主、合作和探究。本课我在引导学生用各种物体发声的实验过程中,并没过分规范学生,而是让学生按照自己的方法、顺序进行实验,并做记录,在整个学习活动中,我将自己作为学生中的一员,与学生一起去探索、去发现,而不是把自己的意志(比如知识结构)强加给学生。在这样亲历探究的体验性学习活动中,师生之间、同学之间的关系是民主的、和谐的。
《标准》指出:“科学课程应具有开放性”作为科学课程的学习主体的小学生,在面对纷繁复杂的科学世界时,会产生无比激情和盎然兴趣,教师必须尊重学生的意愿,以开放的观念和心态,为他们营造一个宽松、和谐、民主、融洽的学习环境,不能把上下课铃声当作教学的起点和终点,科学的探究仅仅凭课堂40分钟是不够的,针对这种情况,本课结束时,我给学生布置了制作“水扬琴“的实践性家庭作业,让在学生能在课外继续去探索声音的奥秘。
以上是我执教《听听声音》一课后的一些想法和粗浅的反思,也许我对本课地理解还不够深刻到位,刚才的教学种也肯定暴露出很多的问题,恳请在座的个位专家和同行多多提出宝贵意见。谢谢!
但是本堂课也存在一些不足:(在今后教学中应该加强的方面)
1、本堂课教学中也存在着一些问题,比如由于本课的活动较多,探究的活动不够深入,发现得不够多,所以在一组学生汇报了自己的小组的发现之后,其他小组的补充比较少。
2、探究过程中材料的提供怎样才能达到最优化,这都是今后教学中需要思考的问题。
3、学生的发言面不是很广泛,主要原因是教师的引导不够到位,平时训练不够细。
