If you’re interested in professional development, or looking to get more involved with the changing face of 21st century education, the Educal is a good resource to use.  It is a calendar and a map that list educational conferences and summits happening worldwide, although most of them are US based.  They also take submissions of eyents, so if you know of a conference near you that’s not on the list, submit it!  The Educal is also looking for attendees to write up reports of the conferences on their blog and there is even an option to sign up for updates about new events in your region so you don’t miss out on anything.
