  2. 2. Definition of web- conferencingWeb conferencing refers to a service that allows conferencing events to be sharedwith remote locations. In general the service is made possible by Internettechnologies, particularly on TCP/IP connections. The service allows real-timepoint-to-point communications as well as multicast communications from onesender to many receivers. It offers information of text-based messages, voice andvideo chat to be shared simultaneously, across geographically dispersed locations.Applications for web conferencing include meetings, training events, lectures, orshort presentations from any computer.Objectives of using the web-conferencing in DE: Use the internet to bring together meeting participants in an online forum for communication. The amount of travel and resources required is reduced significantly, making it a cost-effective measure. It is often easier for people to connect online, making each meeting more efficient. Allows them to share documents, desktops, sound, files and data with one another just as if they were sitting at a table together.Features of web-conferencing:  Slide show presentations - where images are presented to the audience and markup tools and a remote mouse pointer are used to engage the audience while the presenter discusses slide content.  Live or Streaming video - where full motion webcam, digital video camera or multi-media files are pushed to the audience.  VoIP (Real time audio communication through the computer via use of headphones and speakers)  Web tours - where URLs, data from forms, cookies, scripts and session data can be pushed to other participants enabling them to be pushed though web based logons, clicks, etc. This type of feature works well when demonstrating websites where users themselves can also participate.
  3. 3.  Meeting Recording - where presentation activity is recorded on the client side or server side for later viewing and/or distribution.  Whiteboard with annotation (allowing the presenter and/or attendees to highlight or mark items on the slide presentation. Or, simply make notes on a blank whiteboard.)  Text chat - For live question and answer sessions, limited to the people connected to the meeting. Text chat may be public (echoed to all participants) or private (between 2 participants).  Polls and surveys (allows the presenter to conduct questions with multiple choice answers directed to the audience)  Screen sharing/desktop sharing/application sharing (where participants can view anything the presenter currently has shown on their screen. Some screen sharing applications allow for remote desktop control, allowing participants to manipulate the presenters screen, although this is not widely used.)Advantages of the web-conferencing: Save time, money and resources. Easily accessible to everyone. It involves real time communication. Enhance learning via web. (Online teaching, online learning and e-learning). Comes with features such as desktop and application sharing. Web conferencing has a growing role in higher education, for example:  enabling real-time online lectures, tutorials, support and group work for students in different locations;  improving communication and community building between staff and distance students;  allowing staff to use a virtual office to consult with students;  involving guest speakers and external experts in lectures;  assisting academic and support staff on different campuses in coordinating their work with students; and  connecting staff for participation in broader professional networks.
  4. 4. Limitation of web-conferencing: Not all software is free, and the free software is limited in what it can achieve. More informal than face – to – face. Requires suitable hardware and adequate training to be able to function. Depend on the speed of internet. Costs to maintain and keep up with new technology. Technical difficulties. It require computer, microphones, social media accounts and login information. Security breaches. Lack of actual face-to-face interactions and networking that most people enjoy participating in at conventional conferences.How web-conferencing are used to deliver and supportlearning :”Tools” WebEx: Users can share screens, files, schedule video conferences in Outlook just like regular meetings, and easily pass the "presenter" title from person to person so each participant can focus the meeting onto their shared documents or computer screen as the need arises. Tinychat: Sometimes your needs are as simple as getting some people together, for free, and talking via computer as close to face-to-face interaction as possible. Tinychat is a simple service that allows you to stream up to 12 webcams simultaneously while participating in audio and text- based chat. Dimdim: offers a variety of packages ranging from basic and free accounts to enterprise level accounts with tiered pricing. The free account gives you full audio between all parties, public and private text chat, document sharing of PDF and Powerpoint files, web page sharing, a shared whiteboard, and scheduling functionality. Adobe ConnectNow: is a web-based conferencing tool with a strong emphasis on document sharing and collaboration. You can share your screen, share documents, easily convert documents to PDFs, and create workspaces to share and edit documents in.
  5. 5. Concerns about this technology:The concern is related to three points:Security Breaches (Theres always some kind of security risk to communicationcarried out online. In addition to the threat of hackers, youll also have limitedcontrol over people who may overhear the conference.Technical Difficulties (The technological requirements for web conferencing can bea disadvantage unless you do your homework. Most online web conference hostingservices are all-encompassing and only require that attendees have a computer,Internet connection and login information).Human Interaction (Perhaps the most significant drawback to web conferences isthe lack of actual face-to-face interactions and networking that most people enjoyparticipating in at conventional conferences.Case studies & examples: University of Colorado Denver | Anschutz Medical CampusEducational Support Services (ESS) in University of Colorado Denver provides centralizedtechnical (videoconferencing, webconferencing, classroom recording, and audiovisual support)and logistical support for the three-part mission (education, patient care, and research) and theTotal Learning Environment Strategic Goals of the university in a cost efficient manner.More information in this site: University of Tasmania Georgetown University: Web Conferencing—A Critical Skill for the Connected World
