Teleclasses,
Teleseminars, Webinars: New Ways to Stay in Touch
by Jeanette Fisher
Thanks to modern technology, people have more ways
than ever to stay in touch with each other and to
continue learning in the comfort of your own home.
There are many ways to communicate with others,
and as the technology continues to advance, even
more effective ways will be developed.
One of the earliest advances was the chat room,
which allows people to talk to each other via
their keyboards, but not verbally. The
conversation is in real time, and many people can
participate at the same time.
Programs for making free telephone calls over the
Internet to anyone else who also has the program
are gaining in popularity as the calls become
clearer. However, concerns about legal issues
(with challenges to its intellectual property),
traffic security, and political concerns by
governments who want control over their
telecommunications systems, keep many from using
the service.
A popular Internet teaching venue is the recorded
teleseminar, which is made available to interested
viewers via an MP3 download or by clicking on a
button on a website and then viewing the
presentation online. Viewers don't get to
participate during the session, but they can
listen to the information as often as they like,
at their own convenience.
Instructors also use teleclasses to teach their
students. They're similar to teleseminars, but
normally involve fewer participants, and since the
audio portion of the presentation is an open line,
everyone involved can hear everyone else. This
allows unlimited interaction between the
instructor and participants.
Teleconferencing is also popular, although there
is no visual component, since the presentation is
done over the telephone. However, everyone can
hear everyone else, so there is still lots of room
for interaction and discussion between
participants. Teleconferences work well for small
groups, but can get somewhat unwieldy as more
participants join the conversation.
Teleseminars are similar to teleconferences,
especially in that only audio is used to convey a
presentation over the phone, but differs in that
one the presenter or a guest speaker can be heard
throughout the presentation. The advantage to
teleseminars is that hundreds of people can listen
in at the same time, and since the background
noise from all those phones is muted, the
presenter's message is clearly audible to
everyone.
The next step up the ladder is video conferencing,
in which participants can see the presenter on
screen as the presentation is being made. Being
able to see the presenter has many advantages,
allowing for the use of charts and other visual
elements to be incorporated into the event. If the
group is small, many video conferences are
two-way, with cameras on both ends of the line, so
the presenter can also see the participants. This
can be a very effective way to communicate over
long distances, but the video quality is often
below average and can be too expensive for some
organizations to purchase.
Finally, there's a fairly recent technological
advance called a webinar, which is a hybrid of
several of the techniques discussed earlier.
Webinars allow both audio and visual communication
between presenter and participants, either by
means of the telephone or via webstreaming. The
video is delivered by computer, which means that
the presenter is given more options, including
PowerPoint presentations. Since there's real time
audio and visual communication, webinars allow the
most comprehensive interaction between
participants and presenters.
It's a whole new world out there, but as
technology continues to advance, people will be
able to communicate more effectively over long
distances than ever before.
