Displayed over here are some student facing screens of a fully featured Virtual Classroom.
The features of the Virtual Classroom include -
Video Conferencing
Raise Hand (To ask permission to ask questions)
Screen Sharing
Collaborative Whiteboard
Breakout Rooms
Collaborative Documents
Polls
File Manager
Different Layouts including Participant View and Presenter View
All the above mentioned features can be controlled by the tutor. The student has minimum control over the system. The tutor would govern what is displayed on students' screens. This lack of control to the students is implemented so as to keep the number of on-screen distraction at a minimum.
