Screencast Blog Post

A screencast is a pretty much a video that you can record online, and show to others explaining something or just simply talking. 

I personally disliked creating on for class. My reason for disliking it so much was because I always got sidetracked by others, or felt really rushed and watched and like everything had to be perfect. 

I do understand how this could be very helpful though. It could show you how yo do something that you don't understand or teachers could use it in class.
I think it would be most helpful to teachers simply because it makes explaining stuff easier.
