So many new companies coming out with different methods of communicating information and social interactions yet the general populace only see these as fads and work to avoid them.
Even I will use power point to help facilitate my lectures in a virtual world. It isn't power point that is responsible for a good or bad dissemination of information, it is the presenter.
The point of giving information is to have it be digestible to the recipients. Something familiar amid a whole lot of newness allows for a common perception. If it is understandable and usable to their minds at this moment, we have a good connection. So the only way to discern that, is by interaction.
"Welcoming interactions" not "interrupt-able interaction".
People need to feel embraced by their curiosity and encouraged and safe to ask anything. This can be in a classroom or online if all items are available and within the users comfort zone.
So where it is easy to raise your hand in a meeting, it may not be as obvious how to put your question across "just to the instructor" or how to use voice, or the open chat. Some general format questions need to be addressed prior to every meeting. Encourage those that are new to come early.
It is this aversion to appearing "dumb" in front of others that have most people balking at new tools. So if your trying to teach make a "gentle overall method of communication intro" a priority with every event.
I thought about listing the many usable tools and then decided there isn't enough room. Just Google "virtual education" and set aside a month or two for reading and watching.
We are such a fast-food society that often times orientation is left out, figuring they will learn eventually. It is like learning in German when your an English speaker such a hurdle is not desirable. You want your students ready to receive and understand.
