        运动着的世界

        教学目标:

        1、能够提出三个以上自己感兴趣的有关运动的问题。

        2、能够从提出的问题中选出自己认为最值得研究的问题,并能说明自己选择的理由。

        3、能够通过多种途径查阅到一只三角有关物体运动的信息,并且能制成资料卡片。

        4、能够感受到自然界中多种运动形式的奇妙。

        教学重点难点: 能够提出有关运动的问题,学习查阅资料制作卡片。

        教具准备:反映各种物体在运动的图片和录像资料

        教学过程:

        1、导入新课

        播放运动录像

        谈话:风在吹、水在流动、人在走路、鱼在游泳,我们生活在一个运动着的世界。今天这节课我们就来给学习《运动着的世界》。(板书课题)

        评:通过录像引起学生探究运动而你的兴趣。

        2、学习新课

        指导学生认识自然界中的物体具有多种多样的运动形式

        在生活中你们知道哪些物体在运动?他们是怎样运动的?

        学生讨论,汇报讨论结果。

        你们还能举出那些有关物体运动的例子?自然界的物体都在运动吗?学生讨论,汇报讨论结果。

        关于物体的运动,你们还想知道什么?把它们记录下来,并且在自己最想研究的问题上作出标记。学生思考,并且记录自己的问题。

        学生汇报,帮助学生意识到关于运动有许多问题,也许我们今天还不能够很好解决,但是随着自己年龄的增大,在以后的学习过程中,许多问题的答案将会被发现。

        评:注意启发学生的想象引导学生说出更多的物体的运动形式。

        指导学生学习搜集有关运动资料的方法。

        你想了解更多关于运动的知识吗?那么我们就一起来学习搜集有关运动的资料。你搜集资料吗?你有什么好方法?

        学生讨论搜集资料的方法,汇报讨论结果。

        鼓励学生通过多种渠道和方式收集材料资料,教师可以结合自己查阅资料的经验,把自己在报纸上说晚上和网络上查阅资料的经验与同学交流。比如,如何通过标题查阅资料,如何进行快速阅读,教师要特别对学生如何在网上查阅资料、选择信息进行指导,并要提醒学生及时将有用的信息记录下来。

        你知道怎样记录搜集来的资料吗?你有什么方法?

        评:知道学生在网上查阅资料的技巧。

        教师指导:把自己才查阅到的资料记录下来并制成卡片是科学研究常用的方法之一。请你参阅书中的资料卡片和自己设计一个资料卡片,同学之间可以互相讨论,看看谁设计的资料卡片最好!

        学生讨论并设计资料卡片格式。

        请你在下课后收集有关物体运动的资料,并且把它做成资料卡片,看看谁制作的资料卡片最好!谁的资料最完整、最准确!

        评:引导学生经历一个完整的资料卡片的设计和制作过程,让学生体验到独立完成资料卡片制作的乐趣。

        3、本课小节:通过这节课的学习,你知道了什么,你学会了什么?

        4、板书设计:

        课后小记:

        有了问题之后,还要让学生找到解决问题的方法。方法已经找到了,那么该如何来实施呢?小朋友被难住了。此时小小的挫折与刚获得的成功体验形成了一个小小的落差,促使学生要找到验证假设的方法。这就很好地激发了学生的学习动机,使学习成为他们的一种内在需要,他们渴望教师给予帮助。教师在此时介入指导,对学生无疑是“雪中送炭”,他们会很珍惜这种帮助的,这比老师提前灌输给他们要强得多。
