I just recorded my first-ever virtual seminar today! Oh my goodness. It was so strange speaking to an empty room. I drew a picture of some faces and hung it up opposite me, along with a sign bearing the words "SLOW DOWN."
I think this helped.
The seminar is on data visualization, and can be purchased from the Association of Professional Researchers for Advancement (APRA) website.
I am a bit nervous about listening to it, but I am determined to cringe through every "um" and learn some lessons so I can improve my speaking abilities.
UPDATE: 5/15/2011 I still haven't watched it! But I'm still planning to.
