Conducting a Class, Live Over the Internet
In the past, real-time distance learning was conducted using
closed circuit television, which was carried to remote locations
via satellite or by hard wires. Facilities were usually expensive,
requiring special studios, equipment, and trained technicians.
The use of the Internet to carry audio, video, and images offers
the promise of a relatively inexpensive and simple method to
conduct distance learning classes in near real time.
The ability to see the students at both
the host and remote sites is important
for gauging their level of understanding.
In Spring 2002, an experimental class was conducted using
Internet conferencing between the University of California,
Berkeley, and Hanyang University, Seoul. The source of the
weekly lectures was alternated between Berkeley and Seoul.
The results of the experiment offered much insight to the advantages
and challenges of conducting classes using this media. Many
issues were addressed, including those of language, audio and
video quality, international time differences, and cost. Student
evaluations were solicited. The results offer many suggestions
in case an engineering graphics class is offered using this
media.
