I was surprised at the reaction of many of my students to the video The Networked Student. Many said they found all the animation distracting, including some who identified themselves as "visual learners." Students said they had to watch the video two or three times to really take in the content and would have found a text format preferable. True, the video was created in the Common Craft** format where a hand is frequently removing a piece of paper and placing another one on the display board. Perhaps a video created in a different format would not have provoked this "it's so distracting" reaction.
**Common Craft is famous for its Blogs in Plain English, RSS in Plain English, Podcasting in Plain English, and many similar type videos.
