从杨振宁、李永乐和王达峰视频中看课件制作与应用

从杨振宁、李永乐和王达峰视频中看课件制作与应用
不同的人对课件有不同的态度，正好有几个视频，可以从另一面理解课件应当如何做和如何用。
第一个视频来自杨振宁的美与物理学
视频是典型的“念PPT”"书本搬家"，但我想也没有人会指责，也不会有人说PPT美与不美，杨振宁所讲的内容是不是传统的教材知识，更多的是自已的经验，并且自带光环。但如果做课件就是把自己要说的话写到幻灯片上，这并不是一件有趣的事，很多人可能觉得是一种负担，有点无聊，在这个过程中，没有任何创造性，没有内容加工，没有交互设计，在制作课件过程中也提升不了自身的技能。
第二个视频是李永乐讲解病毒的科谱视频。

印象最深的是李永乐教学中展示的板书技能，很多不喜欢PPT的老师，特别是数学教师认为板书可以放慢讲解和推导过程，为学习者留下一点思考的时间。不过我认为如果仅仅是快慢问题，课件很容易解决，课件控制内容呈现顺序和快慢非常容易，更根本的可能是生成问题，板书有一部分可能是即兴，是灵感，但大多数课件内容完全是预设。但遗憾的是板书的这种即兴和灵感如何提取形成可重用的经验呢？
第三个视频是王达峰讲解沟通视频。

讲沟通的人看来更喜欢直接用语言沟通，喜欢通过语言吸引人和感染人，不过从视频讲解内容属于生活观念，并不抽象，这些观念性的内容不需要课件让其具像化，下面视频是一种不同性质的内容。

个人认为教师要从课件制作中获得成就与快乐，可以从补偿性视角设计制作课件，如果仅仅按教学过程做课件，按教学内容做课件都是非常无聊，而且没有必要的，要做那些自己板书不出来的内容，做那些自己讲解不好的内容...这样自己与课件才是互相成就，通过课件能够积累更多的教学经验，课件在教学中很多时候只充当背景，在教学前和教学后更新修改课件内容更有意义，每一次修改都代表自己对教学有新的不一样的理解。
