Definition of the video conferencing :

1.a set of interactive telecommunication technologies which allow two or more locations to interact via two-way video and audio transmissions simultaneously.

2.A technology that allows users in different locations to hold face-to-face meetings without having to move to a single location. This technology is particularly convenient for business users in different cities or even different countries because it saves the time, expense and hassle associated with business travel. Uses for video conferencing include holding routine meetings, negotiating business deals and interviewing job candidates.

5.Connecting with guest speakers and experts.

6.Multi-school project collaboration.

7.Enabling teachers to share information and team-up with teachers in remote sites.

8.Virtual field trips to museums, zoos, aquariums, institutions and other interesting locations that are geographically distant from the school.

(2)•Title: Navigating the Sea of Research on Videoconferencing-Based Distance Education

•Author: Alan Greenberg &Wainhouse Research

•Publisher: Polycom & Wainhouse Research

•This white paper is designed to be a lifeline for practitioners, researchers, and analysts and others who are just starting to look at videoconferencing technology and understand its efficacy. So that this audience can avoid drowning in the sea of distance learning research, this paper provides one industry veteran’s view of the most interesting and instructive research available at the current time. It modulates the din surrounding the field, exploring some of the key issues that occupy those who are committed to exploring how videoconferencing can best be used.
