说课稿篇一
新课程标准理念要求教师从片面注重知识的传授转变到注重学生学习能力的培养,教师不仅要关注学生的学习结果,更要关注学生的学习过程。如课堂中运用“提出问题→分析问题→解决问题”的整体思路,由生活中的“酸雨”提出问题,让学生带着这样的问题去思考、分析、学习,最后解决问题,让学生感受和理解知识产生和发展的过程;促进学生自主学习、探究学习,培养了学生的科学素养和创新思维习惯。
1、教学目标的反思。教学目标是教学活动的中心,是教学的出发点和归宿,在课堂教学中,教师的主导方向和学生的主体活动都是围绕本节课的教学目标来进行的。在目标教学实践中,不应为全体学生设置同一个目标,而应按学生的学习能力、发展水平、智力特点、学习成就以及个性、需要的不同,为不同的学生制定不同的目标。在新的课程理念下设定教学目标,要体现目标设计的人本观、整体性及突出重点目标。有目标地进行教学,可以规范教学行为,避免课堂教学的随意性和失控现象,所以,在未上课之前,制定了以下教学目标:①知识与技能:使学生了解二氧化硫的性质及用途;使学生了解二氧化硫对空气的污染和防止污染的方法;②过程与方法:使学生初步学会设计实验进行探究的技能;学习探究学习和合作学习的方法;③情感态度与价值观目标:培养学生保护环境、绿色化学的思想并用辨证的眼光看待so2。
2、教学方法的反思。恰当的教学方法对于学生学习接受新知识是具有重大意义。改变过于强调接受学习、死记硬背、机械训练的现状,倡导学生主动参与、乐于探究、勤于动手,培养学生搜集处理信息的能力、获取新知识的能力、分析和解决问题的能力,以及交流与合作的能力。教师应当根据自己的教学经验和教训、自己的教学水平、学生的基础对教学方法作适当的调整。
3、引言的反思。新课的引入虽然只有几分钟,但这几分钟或几句话起到的作用却很大。教师应针对不同的课型,不同的目的,将新课的导入设计得生动有趣,激发学生的学习兴趣,达到良好的教学效果。本节课以一段有关“酸雨”的视频引入,触目惊心的酸雨污染情况给学生带来了视觉冲击和心灵震撼,激发学生对酸雨的罪魁祸首—二氧化硫的学习和了解的兴趣。
4、教学内容的反思。《基础教育课程改革纲要(试行)》的印发,打破了化学教材单一的割据,鼓励各地按照新课标的要求开发地方课程、校本课程,教师选用教材的余地进一步扩大。首先,在本节的教学中,不单是讲解高一教材中所涉及的内容即二氧化硫的物理性质、二氧化硫与水的反应、与氧气的反应、其漂白性和二氧化硫的污染情况,而且有机地将将二氧化硫的化学性质分为了酸性氧化物的通性、还原性、漂白性等几个方面作系统的归纳讲解。对于课程内容的先后顺序也作了一定的调整:二氧化硫是酸性氧化物及其通性→还原性→漂白性,这样安排的目的主要在于对整节课的设计是先由酸雨的罪魁祸首引出二氧化硫,讲解二氧化硫的性质时先讲还原性,用二氧化硫与氧气的反应生成三氧化硫回应酸雨的相关问题,课堂设计显得连贯,前后呼应。但教学中容易产生一个误区:只强调so2的污染而忽视了它在我们实际生活中的用途,如作漂白剂、防腐剂等,教学过程中,教师应当给学生强调:化学是一把双刃剑,要用辨证的眼光来看待问题。其次,是教学内容细节上的处理,比如,运用对比教学法,将so2和co2性质的异同进行比较,使学生在对比复习旧知识的基础上接受新的事物,符合学生认知的发展规律。
5、与学生互动的反思。建构主义理论认为:“学习知识不是由教师向学生的传递,而是学生主动建构自己的知识的过程,任何学科的学习和理解都不像在白纸上画画,学习总要涉及学生原有的认知结构,学生总是以其自身的经验来理解和建构新的知识或信息。”在本节课中,如果能将更多的讨论、思考与学生思维互动,效果会更好。
在新一轮的基础教育课程改革的不断推进下,反思性教学已经成为教学的新理念,我们应努力实现新课程理念下的角色转化与自我价值,加强对教学情节的回顾、反思和分析,总结教学得失,改进教学方法,与时俱进,成为学者型、专家型的教育实践者,并寻求一份自我实现的自信与肯定。
说课稿篇二
《形形色色的动物》是教科版小学《科学》四年级上册第一单元《有生命的物体》的第二课。属“生命”板块的内容,是“概念学习”的课型。本课是在学生三年级观察了蜗牛、蚂蚁等小动物、亲身饲养了蚕,上节课观察了解了猫、鸽子、青蛙、甲鱼、金鱼、蜻蜓6种动物的外形、生活习性、繁殖方式和运动方式的基础上,引导学生尝试对动物进行分类,发展学生对动物多样性的认识,并在这个基础上,寻找和概括动物共同特点。为本单元第六课《动物与植物》和后续 “生命”板块的 “生物与环境”“生物的多样性”的学习打下基础。
《科学课新课程标准》提出:小学科学课程是以“培养学生的科学素养”为宗旨的科学启蒙课程。结合本课具体教学内容和四年级学生的已有认知,我把本课的教学目标设定为:
1.经历对动物特征进行探索的过程,获得对动物多样性的认识。
2.按照一定特征对动物分类,能说出动物的相同之处。
3.经历对观察研究结果进行简单整理、概括和交流的过程。
4.培养探索动物的兴趣和与动物和谐相处的环保意识。
第一个教学目标在引入环节观看了《多种多样的动物》视频和在后面 “给14种动物找朋友”探究环节里,学生充分感受到了动物世界的多种多样。目标达成度高。
第二个教学目标学生通过小组活动:给14种小动物找朋友,以及小组内部与组间的交流探讨、资料的学习和老师的引导,最后也顺利完成。
第三个教学目标对研究结果进行简单的整理、小组内部基本能完成。但在交流动物的分类时,一些同学在有不同意见时很激动,尽管老师让他们说出了他们的看法,并同意将这些有争议的动物暂时取出来放一边,等会再研究。但这些学生还在不停地议论,导致小组内的其他同学忍不住用自己的理由说服他,但显然,后面的交流对这部分学生来说形同虚设。在概括每一类动物的共同点时,一些学生开始仅仅以外形或运动方式这些比较表面、片面的认识为依据,但在开展讨论和学习科学家的分类之后,也能理解并基本建立正确的动物分类概念。这个目标中资料的简单整理、概括基本达到,但交流还是不够理想。
第四个教学目标在观看了《多种多样的动物》视频后学生还提到觉得动物世界很神秘、动物们很可爱,产生了想探究动物的兴趣,并在老师的引导下懂得要和动物和谐相处。目标达成比较好。
这节课从学生课堂回答问题和活动记录单的反馈情况来学生在学习之后,发现自己一些想法原来是不科学的,确实对动物的正确分类有所了解,最让人高兴的是:课后,学生提出了很多有关动物的问题想去探究。
根据教学内容和目标,我确定教学的重点是:学生对动物进行分类。
对于四年级的学生,根据教育心理学的研究,他们处在以形象思维为主,抽象思维开始发展的阶段。他们对动物的认识通过三年级和前一课时的学习、课外阅读以及日常生活的接触,是有一定的基础,但还是比较表面和片面。所以我认为本课的难点是1、学生对动物进行分类并抽象成概念;2、对一些“变式”动物进行正确的分类。
本课是“概念学习”的课型,美国教育学家兰本达在关于建立概念体系理论指出:亲身进行各种各样的探究活动是建立概念的必要条件,而“概念学习”的课型在教学中一般要遵循感知——抽象概括——理解运用的逻辑。结合学生的实际情况和教学重难点,我采用了引导——探究——研讨的教学方法。先通过视频让学生感受到动物的多样性和引发学生探究动物的兴趣,并认识到动物分类对研究动物的必要性。然后学生通过“给动物找朋友”开展探究活动,最后经过小组内和组间的交流研讨学习,抽提出各类动物的特征,再用此分类标准来判断 “变式”动物的分类,获得对动物分类的正确认识。这种教学方法紧紧围绕教学重点有效促进教学目标的达成,也体现了学生的学习主体地位。
本节课的学法有探究发现学习法和小组合作学习法。
探究发现学习法体现在学生分组给动物找朋友的活动上,学生先按自己已有的认知对动物进行分类,产生了争议,在老师的引导下,将大家共同认可的动物摆放在一起,再利用已有认知和老师的引导发现抽提概括出大家认可的这类动物的共同特征。这种学习方法有效帮助学生建立各类动物的科学概念,很好解决了“学生对动物进行分类并抽象成概念“这个难点,大大提高了学生的学习兴趣。
小组合作学习法体现在对有争议的动物进行归类和归纳出动物的共同特征上。在大家获得六类动物的分类认识后,老师将刚才有争议的动物提出来,组织学生讨论:按我们发现的六类动物特征,你可以将他们放在哪一类?学生就很顺利将鸵鸟放进鸟类,鲸鱼放进哺乳类。但对蛇还有争议:大部分同学不知道放哪一类,即使个别学生在课外阅读中知道是爬行类的,也不知为什么。这时让学生在小组里阅读“科学家的六类动物分类”资料。学生就对蛇的分类有了比较科学的认识。通过对变式动物的分类,强化了学生科学概念的建立,促进了学生抽象思维的发展。此外,我认为小组学习的不仅要解决研究的问题,更是提供一个平台,让每个学生在有限的四十分钟里有表达自己想法的机会,并学会说与听。
首先,视频导入吸引了学生,引入学习的课题。探究部分由于图片的可操性和形象性,使本来比较枯燥的分类活动变得有趣起来,14种动物中的鸵鸟、鲸鱼、蛇引起了学生的争议。但在小组交流分类结果时,开始我计划让一个小组完成,但在这个小组说到第二类动物的分类时,我发现下面有些孩子开始没有耐心听了,于是改变策略,每一小组汇报一类动物的分类,让更多小组参与进来,也促进了孩子的倾听。在研讨环节概括每一类动物的特征时,我开始采用一边汇报分类,一边追问为什么这样分类的方式,学生的回答比较片面,老师补充的比较多,后来我先让学生将所有的分类汇报完成之后,再让学生小组里挑选两类自己喜欢的动物进行分析讨论,找出他们的共同特征,虽然花多了一些时间,但经过思考和交流,学生的回答全面一些了。例如对猫、羊、马哺乳动物:学生刚开始说出它们外形很像,有头、颈、躯干、四肢、尾五部分,身体有毛。但小组讨论后能说出是胎生哺乳。学生经历了对动物的分类探究活动,最后非常顺利地归纳出了动物的共同特征。一些学生课后还觉得老师准备的阅读资料自己学的还不够细,,要求老师再单独给他一份,回家好好研究。
总的来说,本课各环节的设计合理,实施起来也比较顺利。
《形形色色的动物》这节课学生的参与度很高,学习兴趣浓厚。通过探究、研讨等活动,学生在知识、技能和学习兴趣等方面得到了一定的提高,尤其促进了他们抽象思维的发展。
1、上课语言要精炼。
2、有了电子白板后,学生的汇报可以请小组在白板上拖拉动物到相应的位置上,比直接拿着记录单来说,交流的效果会好一些。
3、由于时间比较紧,学生学习科学家的六种动物分类时,学生的阅读时间比较短,结果学生只是理解了蛇应该分在哪一类动物里,没有让学生反思自己的分法和科学家的分类分法的差异。所以应该为每一位学生准备这份资料,让学生在课外继续学习,真正理解科学家的动物分类方法。
4、学生的交流不够理想,可能更好的处理方法是给点时间让学生在组内说出自己的观点,汇报时还有意见的,也让他发表一下。不要让他觉得有话不能说,结果一直在下面喋喋不休,影响同学的交流与倾听。
说课稿篇三
各位评委、老师:
大家好!
今天我说课的内容《直线、射线、线段》是选自人教版教材七年级上册第四章第三节的第一课时。下面我将从教材分析、说教法、说学法、说教学流程几个方面说说我对这节课的设计说明。
1、地位和作用分析:
本节内容是在学生学习了前面一节线段、射线和直线数学概念后,回过头进一步认识线段的特性,即通过“叠合法”、“度量法”对线段进行长短的比较,“尺规法”画线段等于已知线段或画已知线段的和、差、倍等,从运动变化的角度,用数形结合的观点加深对线段的认识,同时也是进一步学习平面几何的基础性知识,在今后的几何学习中,“叠合法” 、“尺规法”还有较多的应用,所以它在教材中处于非常重要的位置,不仅在知识上具有承上启下的作用,而且为今后进行几何的计算和作图提供了方法和依据。
2、教学目标分析:
依据学生已有的认知基础和已有的经验及本课教材的地位、作用,依据九年义务教育数学教学纲要确定本节课的教学目标如下:
【知识与技能】
1、会一条线段与已知线段相等。
2、使学生发现线段长短比较的一般方法。
3、会用几何语言表示两线段之间的大小关系。
4、了解线段线段和、差的概念。
5、会画一条线段等于已知线段,会画两条线段的和、差。
【过程与方法】
1、经历将实际问题抽象为数学问题的过程;
2、经历个体思考、小组交流、全班交流的合作化学习过程;
3、渗透数形结合的数学思想方法。
【情感态度与价值观】
1、培养学生应用数学的意识;
2、让学生体会数学的应用价值。
3、教学重点和难点分析:
【重点】探求线段长短的比较方法,尺规法的运用。
【难点】线段的和差的概念涉及形与数的结合。
鉴于教材特点及初一学生的认知水平,我选用引导发现法和直观演示法,引导发现法属于启发式教学,通过教师的引导,启发调动学生的积极性,让学生在课堂上多活动、多观察,主动参与到整个教学活动中来,这符合现代教育理论中的“要把学生学习知识当作认识事物的过程来进行教学”的观点,也符合教学论中自觉性和积极性、教师的主导作用与学生的主体地位相统一的原则。同时在教学中,还充分利用教具,在实验,演示,操作,观察,练习等师生的共同活动中启发学生,让每个学生动手、动口、动眼、动脑,培养学生直觉思维能力,这符合教学论中直观性原则与可接受性原则。
借鉴杜威的“做中学”的思想(即最好的教育就是"从生活中学习"、从经验中学习"的思想),在教学设计时,让学生充分动起来,通过猜一猜、画一画、辩一辩、说一说、做一做等活动,调动学生动手、动脑,并经历个体思考、小组合作、全班交流的合作化学习过程,培养学生的想象能力和直觉思维能力。
(一)、创设情境
新课程下的数学教学要求教师给学生提供一个与现在的社会生活经验相联系的情境,在问题情景之下,发挥学生自主参与、积极探究的主体意识,激发学生的好奇心及求知欲,充分调动学生的积极性、主动性,为此我创设了如下教学情境:
通过教师擦黑板,老师没有擦到而是找了一位比老师还矮的同学来擦,然后学生掂起脚擦到了,教师很幽默的问大家:“这是不是说明这位同学要比老师高呢”从而引入本节内容。
设计目的:通过创设适合的问题情景,使学生对故事情节深入思考,找出解决问题即是要比较线段的大小,从而引出课题 。
(二)、实践探究
1、出示一条线段,怎样做一条线段与这条已知直线相等。让学生发挥想象自己归纳总结出两种画法。
(1)度量法(2)截取法(使用量角器)
2、生活感悟:
①通过实物的比较与方法的运用,初步明确两个实际物体的长短或高矮的比较方法。(可能出现的方法:度量法,叠合法)
②请同学们举出一些日常生活中的物体,说明怎样比较你所举出的实例的长短 (可比较长短或高矮的物体)
学生活动:(2—3分钟)同桌交流,全班汇报
设计目的:通过学生之间的交流,充分感悟生活中实物长短的比较
教师准备基本工具:刻度尺,圆规,米尺,细绳
3、实验演示:
方法一:将实物抽象成线段,探求线段长短的比较方法。
如果ab与cd相等,我们可以记为ab =cd(或cd=ab)
如果ab比cd短,我们可以记为ab
ab).
如果ab比cd长,我们可以记为ab >cd(或cd方法二:我们还可以通过量出各条线段的长短来比较线段的长短。
表示方法:试用几何语言表述两线段比较可能出现的结果。若两线段为线段ab、线段cd,则有如下结论:ab
cd
活动目的:使学生对抽象的知识的了解有一个生动、直观的体验,同时通过个体学习,合作学习,完成知识从感性到理性的转化,使学生经历知识的发生,发展过程,而在这一过程中教师完成角色的转化既成为学习的合作者,参与者。(三)、应用实践
1、练一练
(1)全班分组,每组分别画锐角三角形,直角三角形,钝角三角形;
(2)同桌交换,估计三条边的大小,再利用手中工具(直尺、圆规)来检验你的估计。并用几何语言来表达。
学生活动:个体独立思考并利用工具操作、小组讨论交流、小组代表在全班汇报
活动目的:学生学会用直尺,圆规来完成度量法与叠合法,变感性为理性,达到即学即用的目的,从而让学生体会各种方法的利弊,同时达到巩固的目的。
3.画一画
1.如图,mn为已知线段,你能用直尺和圆规准确的画一条与mn相等的线段吗?
2.如图,已知线段a,b,画一条线段c,使它的长度等于已知线段的长度的和。
结论:线段c的长度是线段a,b的长度的和,我们就说线段c是线段a,b的和,记做c=a+b,即ac=ab+bc 。
变式练习:上题中,若线段a的长度小于线段b的长度,请你画一条线段c,使得它的长度等于两条线段的长度之差。
根据图形填空:
1、ac= _ _ _ _ + _ _ _ _
2、此时 ab= _ _ _ _— _ _ _ _
线段a是线段c,b的.差,记做a=c-b (即ab=ac-bc)
补充例题:已知线段a,b,利用直尺和圆规画一条线段c,使它的长度等于
(1)c=2a (2)c=3a-b
活动目的:培养学生认识图形的能力,复习大小比较方法,更重在培养发散性思维能力,且巧妙地让学生理解线段的和差倍的意义。
(四)应用巩固(导学案)
(五)归纳总结:
学生自评:独立完成小结,用自己的语言梳理本节课的内容,总结本节课学习中的收获,困难。
本节课中,在教学过程中注重学生学习方法的培养,重视数学知识的形成过程,尽可能多的采用体验学习,探究学习,合作学习,自主学习,同时不排除使用接受学习。
以上是我的设计说明,敬请各位领导、老师留下您宝贵的建议,谢谢!

说课稿篇五
尊敬的各位评委:
上午好!今天,我说课的题目是《热的传递》。我将从以下七方面进行阐述:
今天我说课的内容《热的传递》是苏教版小学科学四年级上册第二单元《冷和热》的第二课,这一单元主要是根据课程标准中“能的表现形式”和“物体与物质”中的部分要求建构的。从结构上看,这一单元探究的都是生活中一般的热现象及简单的规律。
而本课是学生在认识温度的基础上,指导学生研究三种形态的物质用什么方式来传热(即传导、对流和辐射);使学生认识热是从高温处向低温处传递;并能解释生活中有关热的传递现象。本课是从另一个角度对热现象的研究。同时也是后面《加热和冷却》、《吸热和散热》的研究基础和铺垫。
冷和热是生活中常见的现象,如气温的高低、物体的冷暖、加热、制冷等,学生都有丰富的生活感知,但他们对冷和热的认识,更多时候还是停留在自我感觉的层面,对很多冷热现象,并没有刻意地关注,还不能作出合理的解释,因此,当教材引领学生聚焦生活中一些常见的冷热现象时,当他们面对熟悉的现象而产生迷茫时,探究的欲望是何等的强烈,这就是学习的内在动力。
根据以上教材分析,结合学生的年龄特征和认知规律,我制定了以下教学目标:
知识与技能:1、 知道热总是从高温处向低温处传递;2、 知道传导、对流、辐射是热的三种传递方式;3、 能正确使用酒精灯。
过程与方法:1、 能通过实验理解热的三种传递方式;2、 能使用酒精灯帮助完成实验;3、 能运用热的传递知识,解释生活中的一些现象。
情感、态度、价值观:1、 能保持积极的观察实验的兴趣;2、 体验通过积极思考和探究所获得成功的喜悦。
根据课标要求,在吃透教材的基础上,我确定了本课的教学重点和难点:
教学重点:认识热的三种传递方式 教学难点:正确使用酒精灯
在设计本课时,我关注了对学生的思维引导,整堂课就是一个完整的科学探究过程,采用“生活情境——提出问题——实验探究——解释问题”的教学模式,通过与生活息息相关的教学情境,驱动学生的好奇心,根据生活经验对该教学情境可能产生的结果进行猜测,引发学生的问题意识,并在这一问题的引领下,进行有目的地探究,寻找问题的答案,再利用答案,解释相类似的生活问题。因此我将本节课教学流程设计为:1、 游戏导入、激发兴趣 2、 自主设计,认识热传导 3、 合作探究,认识热对流 4、 讨论交流,认识热辐射 5、 巩固延伸,拓展应用
为完成教学目标,我设计了以下教学过程:
(一)游戏导入 激发兴趣:
课始我以小魔术:《灵敏的鼻子》入题,让学生猜测魔术中的秘密,之后再创设冬天的情景,让孩子们想办法利用哪些东西,让老师的手马上热起来?
这样设计可以激发学生的积极性,让他们在猜测中唤醒对知识的探究欲望,并通过生活化的探究与引导,获取知识的共鸣——热是从高温物体向低温物体传递的。
(二)自主设计 ,认识热传递。
对于热传递的研究,首先从研究热在固体中的传递开始,这个环节,我以研究热在铁棒中的传递为主要任务展开教学,通过下面六步展开:1、 提出问题 ;2、 进行预测 ;3、设计实验;4、实验验证;5、讨论分析;6、拓展应用。
同时这也是一个典型的科学探究的过程。而科学探究总是从问题开始,“铁棒中的热是怎样传递的呢?”这个问题,来源于生活,但学生平时很少去思考其中的科学道理,科学课的重要任务,就是要通过不断地引导学生聚焦生活现象,发现、探究、解释其中的奥秘。学生的预测,是学生最初的理解,对于这个问题,我安排让学生画出他们认为的传递路线示意图。有了自已的预测,实验是最好的验证方法,于是我放手让学生自主设计实验。四年级的学生,经过三年级一年的科学学习,是具备设计简单实验的能力的,同时,这也可以培养学生的设计实验能力,为以后的教学打下基础。
学生可能设计的方案:
1、 把开水作为热源,把铜棒的一头放入水中,不断地用手摸,感觉热的传递的过程。(此方案,能感觉到,但不能够看到)
2、 把酒精灯作为热源,在铜棒的一头加热,感受热传递的过程。 (此方案,较危险,用酒精灯加热,铜棒的温度较高,容易烫手,而且也不能看到传递过程)
3、 把酒精灯作为热源,在铜棒上用凡士林粘住数根细木棒,在铜棒的一头加热,利用观察细木棒掉落的顺序观察热传递的过程。(此方案较佳)
(三)合作探究,认识热对流
热在固体中的传递方式是热传导,而在液体和气体中的传递方式是热对流,为了让学生正确认识热对流,我设计了以下教学环节,其主要步骤和“研究热传导”大致相同,主要包括以下几个环节。
1、提出问题:热在水中是怎样传递的?
2、进行预测:在图上画出水的运动路线
3、设计实验:主要解决什么方法能让我们看到水的运动
4、实验验证:学生分组实验讨论分析:得出结论,热在液体中的传递方式是对流。
5、拓展延伸:热在气体中的传递方式也是对流吗?谈谈生活中热对流的应用实例,如空调的位置等。
(四)讨论交流,认识热辐射
接着引导学生认识热辐射,首先提出问题:在夏天的烈日下,为什么物体摸上去很烫?
通过讨论让学生认识到,太阳将热传递到地面上来,既不是传导,也不是对流,像太阳这样,不靠空气或其他物体也能传热,这种热传递方式叫“辐射”。
(五)巩固延伸,拓展应用
此时,学生已经掌握了热的三种传递方式,为进一步让学生理解、区分这三种热传递方式,我设计了让学生分析图中的热传递方式这一环节。
至此,完成本课教学目标,故而形成板书:
2、热的传递
温度较高 温度较低
由于采用了实验法,运用了多媒体教学手段,我在黑板上只书写了上述文字,简洁明了,让学生一目了然,对所学知识留下深刻印象。
六、说课堂评价在课堂的评价中,老师要注重学生的自评和互评,注意采用划分等级的办法,使评价结果得以量化,显性化。主要从以下几个方面来评价学生。1、能否积极主动的参与到科学探究活动中来。2、能否把学到的科学知识灵活的运用到日常生活中来。3、能否积极主动的与同学进行交流、合作。4、能否倾听其他同学的不同观点,并改进自己的探究。5、我比以前有进步吗?
七、说课程资源开发
对于课程资源的开发与利用,我感觉,
首先是要活用教材资源。比如:在第一个探究实验中教材中使用蜡烛来粘住小木棒,而通过实际操作发现用蜡烛粘对学生来说不易操作。因此我选择了生活中常见且更易于操作的凡士林。
2.善用生活资源,在实验探究的实施过程中,借助生活情景和经验,促进有效问题的产生,明确研究方向。本课探究实验中所利用的材料就是生活中常见易得的。
3.巧用多媒体资源。学校已实现了电子白板“班班通”,不仅可以播放各种多媒体课件,还能播放视频直观演示教学内容。比如热辐射概念很空洞,很难理解,可以利用网络视频,使学生直观了解更多关于热辐射的知识。
