CIT has integrated the Centra, a Virtual Classroom tool, with IVLE. Interactive and collaborative lectures/tutorials can be conducted online involving students anywhere around the world using IVLE's Virtual Classroom software.
The simplest ways to conduct tutorial sessions online is via IVLE chat rooms (live) or IVLE discussion forums (asynchronous). However, you may want a more dynamic and interactive environment to conduct your lessons. This is where web conferencing is useful.
