Videoconferencing is a form of
technology that allows two or more people at different locations to see and
hear each other at the same time by using computer networks to transmit audio
and video data.
Videoconferencing
roots were established in 1956 when AT&T created the "picture phone."
This telephone allowed the caller to see an image only once every two seconds.
This limitation did not sit well with the public and so by 1964, AT&T improved
their modeled picture phone and invited the public to place calls between two
locations: Florida and New York. Users of the new model were interviewed by
a marketing agency and it turned out that the public just didn't like Bell's
picture phone. The equipment was too bulky, the picture too small, and the controls
were too unfriendly. Bell kept on trying and two decades later with the implementation
of a desktop computer that housed the picture phone and the improvements in
digital speed, image quality, and control buttons, Bell finally marketed a prize
possession, a personal video communication system.
- Live and Synchronous
- Immediate Comments and Dialogue
- Immediate questions/answers
- Can improve students' memory
retention by appealing to a variety of learning styles
- Lectures/teaching models can
be transferred easily to videoconferencing
- Provides access to the visual
data (video and audio clips, graphics, animation)
- Nonverbal communication cues
that reassure us in our discussion process
- Participants can jointly view
and discuss images
- Can bring many people together
from different locations and share ideas, share data, opinions, observations
- Can reduce miscommunication
- Is adaptable to many locations
- groups can be linked in to an individual host/facilitator

- Requires specialized equipment
- Availability of bandwidth may
not be enough to produce a smooth image quality or that the cost of upgrading
telephone lines to achieve it would be expensive
- Cost of equipment can be expensive
to purchase or rent, since each location would need access to it
- Technology can be distracting
and difficult to use
- Demands a fixed time schedule/transmission
time
- Difficult to coordinate with
participants in different time zones or with different schedules
- Not suited well for text-based
presentation
- Dependent on other channels
of communication for a good flow of communication
- Participants sometimes are not
trained in conference etiquette and therefore don't specify who questions
are addressed to.
- One author stated it's hard
to be creative in video-conferencing
- Power outages and network failures
- Shy participants
- Uncooperative facilitators
- Mixed abilities of participants
and/or facilitators
- A multimedia Macintosh or PC
desktop computer
- A computer sensitive hands-free
Microphone
- A set of computer speakers
- A sound card (this is used to
process audio)
- Digital Video Camera
- Headset (if you prefer)

- When the teacher calls on your
school, speak clearly and distinctly in your microphone

- If you are not sitting at a
table, take your name sign with you to the microphone
- Remember these sessions are
being videotaped. Others will watch the tapes so make a good impression.
- BE CONSIDERATE OF OTHERS
