FETC, the Florida Educational Technology Conference, is a huge national conference held in January. They also run a virtual conference which is OPEN RIGHT NOW!
The virtual conference runs from 10am to 6pm and everything will be archived for future reference if you can't get online today.
The site is easy to navigate and contains video presentations, discussion forums, downloads, vendor sites, and more. It is well worth your time and everything is archived for future download and viewing if you can't attend in real time.
You can register for it here and get more information.
I highly recommend it to anyone interested in learning more about educational technology and how it can improve teaching and learning. I "attended" last year's and got a lot of great information and resources, as well as making some connections with colleagues from all over the world.
I was invited to present at FETC 2010, but I am unable to attend due to a back injury that will prevent me from traveling to Florida. I do recommend the conference to others.
