Google Chromecast: Wireless Display For The Classroom?

Once students bring their own devices to class, it would be useful to be able to put their output up on a classroom projector. Doing this wirelessly is really the only practical way I think so I have been watching the technology. Back in 2010 I wrote a post called Wireless HDMI Comes of Age. Now, Google has just announced a little HDMI dongle called Chromecast that allows an Android based device to push content to the remote display. Now, from what I can tell, it’s not actual screensharing. Instead, you can send content including YouTube links to Chromecast. Once it has started playing, you can then do other things on your device. Here’s a video demonstration.

The problem as I see it, is you need some kind of gatekeeper app for the teacher to use, or else it would be anarchy in the room. This app would show requests of students to show content and then the teacher would approve them. The problem with this is it’s a very niche market so I’m not sure Google would care about it.

Where this will work nicely, is if a teacher has an Android tablet they would be able to walk around the classroom and still be able to send content to the projector. Nice.

Still, the technology looks ready and is pretty cheap too.

Here’s an article from USA today on the technology and compares it to Apple’s Airplay.



  1. I would strongly suggest looking at Actiontec ScreenBeamPro Education Edition. This is a true Miracast wireless display solution which addresses all the issues of use and deployment within an educational environment.
