点亮小灯泡教学反思

点亮小灯泡教学反思 点亮小灯泡 我在教学《点亮小灯泡》一课中首先进行的是比谁能把小灯泡点亮，稍过片刻，陆续出现有小组的同学点亮了小灯泡，学生一副得意的样，其实我心理非常明白这仅仅是一节课的开端，于是我跟学生说:“点亮小灯泡固然能干，但这并不是最稀奇的，稀奇的是你要思考为什么小灯泡能亮，如果知道原因了才算是稀奇呢,如果能说出原因的同学加5分(因为平时加分基本是1分、2分，这次有5分加，学生就非常来劲了。)。”当我说完这个话时学生就在思考为什么能亮……等等。我想这个时候学生的思维应该打开了，他们还说得津津有味……。 但是这节课还是引起了我的思考:思考一:学生学习通路时始终是有一定的困难，应该用怎么样的方式教学，学生才能容易懂呢,网络上二剪梅老师的方法我想应该是很好的，我也在课堂上用到了，能帮助学生有所了解，但是学生还是迷惑不解。想想能否通过动画的方式出现，以一种非常卡通的形式，帮助学生来学习，或许会有帮助，。这是在我观察女儿学习的时候想到的，女儿学习文字和符号之类的知识感到特别乏味，当她看到图画，动画的之类的图片时特别感兴趣。所以我想能否用这种方式来学习，当然要有一定的计算机基础才可以完成动画的制作。 思考二:学生的学习合作组的改变，会有不一样的收获。曾经是四人一组进行学习，今天这节课的学习材料是每人都有一份，所以让学生自己独立完成，观察之，学生独立完成有一定的难度，30位同学大intensive development.
