Google Cast for Education is a free Chrome app 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 app 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 app, and students share their screens using the latest version of the Cast feature in Chrome.

Teachers can select the level of access for each student or class clicking Cast .

• Can present—Students can cast to your screen anytime you have the app open.
• Can request—Students can request to cast; you need to Approve or Deny each request.

Some teachers in our pilot changed permissions to Can present before a class to let students present freely. They changed back to Can request when they wanted to review student cast requests.
