7. First we shall speak about how and with what tools synchronous communication
implemented in vle
The main tool that used for this type of communication is Videoconferencing
Videoconferencing for educational purposes is an innovative scheme using
at wide range state-of-the-art equipment.
Advantages
• Allows immediate, real‐time interaction.
• Allows all participants to see and hear each other.
• Can display pictures, graphs, maps, small objects etc or play a video tape.
• Can demonstrate a piece of equipment or technique.
• Works particularly well with small groups at each site.
• Camera and monitor control able to be managed locally or remotely.
• With desktop systems you can share computer files and work collaboratively.
• Facilitates student interaction.
Disadvantages
• Specialist equipment needed.
• Needs high level of instructor planning.
• Costly if a large number of sites are involved.
• Restricts room layout, instructor movement and student seating.
• Requires instructor to manage video and audio inputs from several sites.
• Behaviour has to be modified for large multipoint conferences.
There are two significantly different types of videoconferencing. The first is a
point‐to‐point videoconference, where a link is established between two
terminal endpoints.
The second videoconference scenario is a multipoint conference, where a
videoconference is conducted between three or more terminals.
