Preparing students for an active participation is a
prerequisite for the success of teleconferencing. The
student should know in advance about the content to be
discussed and the objectives to be achieved.
4.Conduct the actual session:
The session should be interactive so that all the
students can actively participate and learn as much as
they can from the conference session.
After the conference is over, the necessary feedback
should be obtained from the students. This will also help
the students to know their performance.
