Free Online Virtual Classroom
WiZiQ's free Virtual Classroom is an online internet mediated classroom where the teacher and the students are connected to share a common workspace. In this online session, they make use of audio-video conferencing, text chat, whiteboard, and content sharing capabilities. There are no costs for using the virtual classroom. The sessions are recorded and are available online on WiZiQ, which can be accessed for later review or reference.
Attendees can join a session with privileges to converse verbally with others; draw and write on whiteboard; and share Presentations, PDFs, Flash and Images. The teacher may withdraw or re-assign these privileges to the attendees. A Teacher can withdraw privileges from the attendee in terms that the attendee can not converse, or upload anything to share on whiteboard; in this case, the attendee is a spectator. An attendee can also request for rights, in which case, the teacher can click on the attendee’s name to transfer control.
