2. Definition of the video conferencing :1.a set of interactive telecommunication technologies which allow two ormore locations to interact via two-way video and audio transmissionssimultaneously.2.A technology that allows users in different locations to hold face-to-facemeetings without having to move to a single location. This technology isparticularly convenient for business users in different cities or evendifferent countries because it saves the time, expense and hassle associatedwith business travel. Uses for video conferencing include holding routinemeetings, negotiating business deals and interviewing job candidates. 3. Objectives of using the videoconferencing in DE :1.assist teacher to deliver high quality of teaching andlearning.2.opens up possibilities for collaborative teaching and learningto make best use of resources.3.provide live support for students at remote sites.4.give access to expertise not available within the institution. 4. 5.Connecting with guest speakers and experts.6.Multi-school project collaboration.7.Enabling teachers to share information and team-upwith teachers in remote sites.8.Virtual field trips to museums, zoos, aquariums,institutions and other interesting locations that aregeographically distant from the school. 5. Advantages:1.Collaboration with schools where the pupils come from different culturesleads to the development of multicultural relationships and understanding.2.Can provide access to at-risk or special needs students.3.Provides additional access to students at remote sites.4.Faculty and staff needs can be met more quickly through just-in-timetraining.5.provide students with opportunities to work with their peers from otherinstitutions and countries.6.users can see each other, which allows them to develop strongerrelationships.7.Reduce travel costs. 6. 8.Improve use of executive time.9.Speed up decision-making.10.Keep meetings brief and more focused than face-to-facemeetings.11.Enable top management to quickly and effectivelycommunicate with employees sitting in multiple locations.12.Allows virtual project management via video and dataconferencing with geographically dispersed peer groups at shortnotice.13.Provides an effective way of delivering cost-efficient trainingto individuals without the requirement to consistently travel tocentral locations.14.Creates a medium for conducting interviews. 7. Limitations:1.Technical difficulties associated with smoothtransmissions that could result from software, hardware ornetwork failure.2.Absence of technical support personnel for participantswho are unfamiliar with videoconferencing.3.Lack of personal interaction.4.High costs for videoconferencing and broadcastingvideo.5.Security issues. 8. Using Of Video Conferencing To DeliverAnd Support Learning:1.Enhanced motivation2.Improved communication and presentation skills3.Increased connection with outside resources4.Effective learning environments5.Expanded teaching capabilities6.Links to people from different social, cultural, andeconomic backgrounds 9. By Researchers And Distance Students/TutorsAbout This Technology: (1)Title: Video Conferencing in the Field: A HeuristicProcessing ModelAuthors: Carlos Ferran & Stephanie WattsPublisher: Management Science , vol. 54, no. 9This research uses dual-process cognitive theory todescribe how people process information differently whenit is delivered via videoconference rather than when it isdelivered face-to-face 10. (2)Title: Navigating the Sea of Research on Videoconferencing-BasedDistance EducationAuthor: Alan Greenberg &Wainhouse ResearchPublisher: Polycom & Wainhouse ResearchThis white paper is designed to be a lifeline for practitioners,researchers, and analysts and others who are just starting to look atvideoconferencing technology and understand its efficacy. So thatthis audience can avoid drowning in the sea of distance learningresearch, this paper provides one industry veterans view of the mostinteresting and instructive research available at the current time. Itmodulates the din surrounding the field, exploring some of the keyissues that occupy those who are committed to exploring howvideoconferencing can best be used. 11. Examples Of Video Conferencing :1.Desktop conferencing using the Internet (IP) network :This system uses the Internet to link desktop computers runningvideoconferencing programs.Advantages:It is cheap: You need any PC, an Internet link, cheap videocamera and microphone.It is accessible: you can videoconference from your own desk atany time. 12. Disadvantages :Sound and picture are very poor quality.You are dependent on an Internet connection whichcan be very slow.It is not suitable for medium or large groups ofpeople to use gathered round a PC. 13.
