A virtual classroom is form of web conferencing that integrates many real-time online communication facilities, including text chat, slide presentations, audio/video conferencing, electronic whiteboards and application sharing. Virtual classrooms differ only marginally from mainstream web conferencing, in that they integrate with learning management systems and can provide features such as interactive questions, activities in syndicate groups and evaluation forms.
Virtual classrooms can be used to host one-to-one coaching, small group discussions, classes and seminars (often labelled as 'webinars'). Sessions rarely last longer than an hour.
The most popular virtual classroom packages are Centra, Interwise, Webex and Microsoft LiveMeeting and Breeze.
