It seems that all those that could not be heard were basically suffering from a problem related to how they initially setup, using the webex audio setup wizard. It would seem that everyone could hear me clearly, which was obviously very important especially for those participants that were in the unfortunate position of not being able to be heard. With regard to muting of participants it was obvious that a lot of background noise could be heard at various times and a much stricter outlining of ground rules to highlight no distractions or using the mute if you are aware of the potential of background noise to interfere with the lesson. Participants also have the ability to mute themselves as long as they select their own name first on the participant panel.

The facilitator also has the ability to mute participants which is useful. This is achieved easily by the facilitator. The microphone is passed around to those not in possession of a free microphone who wish to speak. The system limits speaking to seven people at one time, which seems to be better than most competitors. Using VOIP the system overall seems to have worked very well. The key technical issue is the quality of the audio.

Video conferencing has not been used, but there is a facility to view 6 webcams at once if desired. The online communication tools I.E whiteboard text and drawing tools, innovative pointer tool, text chat and feedback icons have been easily adopted by the participants for use in the session. Having just completed three online Interactive synchronous classes with eight of my teaching colleagues on the subject of Web 2.0 technology I thought it was time to review the environment from a technical point of view.
