    怎样正确、有效的使用课件?

     

    多媒体课件作为课堂教学的辅助手段,对更好的展开课堂教学,具有举足轻重的作用,但怎样使用,使课件真正成为教学的帮手,却是大有讲究的,具体表现在以下几个方面:

     

    一、设计为主,课件为辅,不让课件牵着我们的鼻子走

     

    多次听课,在与上课老师交流时,发现这样一个有趣的现象:不用教材配套光盘,20分钟就能教完的内容,用了配套光盘,需要25-30分钟才能结束。为什么会这样呢?反思现状,寻找原因,关键就在于教师预设的教学设计与课件本身的顺序不吻合,甚至完全没有多大的联系,只是考虑到有人听课,需要使用多媒体,而本课内容的教学是否真的需要如此课件,却没有充分考虑,导致教师的教学与课件的呈现互相之间契合不好,使得课件反倒成为课堂正常教学的附庸,白白的增加、延误新课结束的时间。

     

    要避免上述情况,我们该怎样做呢?

     

    二、以教学内容为源,设计实用的课件

     

    备课时,预设好不同内容的呈现方式,或板书,或讲解,或课件演示等,再将需要课件演示的内容制作成课件,在课堂教学时,予以出示,给学生提供需要思考的素材和问题,使课件成为其他活动形式不可替代的部分,体现课件演示的必要性和重要性。

     

    三、以教学预设为线,设计好课件切换之间的过渡语

     

    为使课件切换更为自然,还应精心设计每次的导入语与过渡语,使已一张幻灯片向另一张幻灯片的切换更加需要与自然,避免直接切换,跳跃幅度太大。更要注意的是,千万不能内容已经教完了,课件还没有相应的出示,或者教师说的内容与课件展示的完全不一致。

     

    所以,课件作为课堂教学的辅助手段,只有设计好,使用好,才能发挥辅助作用,帮助学生更好的理解学习内容,更好的达成教学目标。

     

    以上只是听课时的一点想法,既是提醒上课教师,更是提醒自己。
