Google Cast for Education is a free Chrome extension that allows students and teachers to share their screens wirelessly from anywhere in the classroom. Cast for Education carries video and audio across complex school networks, has built-in controls for teachers, and works seamlessly with Google Classroom.
The Cast for Education extension runs on the teacher’s computer that’s connected to the classroom projector, and it doesn't require new hardware. Teachers receive casts through the Cast for Education extension, and students share their screens using the latest version of the Cast feature in Chrome.
Note: If you tested Cast for Education in beta, you'll be automatically upgraded to the full release of Cast for Education with version 52 of the Chrome browser.
