Google has come up with a green room to check out all the factors and make sure everything is working before even joining a call. In this room it will quickly allow you to preview what you plan on doing and will signal any errors or trouble it finds.
The Green Room allows…
Teachers to practice lessons plan on teaching
Students to check there connection
Administrators to check technology before meetings

This image above is a preview of what you would see when joining the green room. Where you would be able to test everything out that you plan on doing.
This new technology is important to know about because…
Can make teachers feel more comfortable about trying new things in the virtual class setting
Previewing things allows everyone more comfortable in the call knowing the connection is well
Allows you to spot problems before you are in the call
Can get the problems fixed before you join the call
