Up until now, screencasting on a Chromebook has been tricky; the only way to do it was through a Google Hangout on the Air.
In the video below, Tech Leader Suha walks you through a new way to screencast on your Chromebook. But there's more!
You'll notice that Suha is screencasting a Google Presentation in this video. What she's showing you is that you can actually create embedded presentations with narration using nothing but a Chromebook now. It's pretty easy. Next time you're asked to make a photo story or give a presentation, you've got what you need on your Chromebook.
