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 Wi-Fi school networks, has access controls for teachers, and works seamlessly with Google Classroom.
How it works
The teacher sets up Cast for Education on their computer that’s connected to the classroom projector. The teacher then invites a student to cast their screen. The student casts their screen to the teacher’s computer. The teacher can then project the screen to the class.
Note: Cast for Education is designed for G Suite for Education users.
