Did you know that Google is running a free Mapping with Google course?
It is a self-paced course that includes videos, mini lessons and activities to apply what you've learned. None of it is graded, and you don't have to show anyone your work if you don't want to. However, there are class forums and Hangouts for a fuller learning experience.
I signed up for it and am through all of the published sections so far. Much of it I already knew how to do, but I did come up with a great idea to use Maps or Google Earth (I can't decide which) to illustrate the 100-year story of the Lenertz family line from Luxembourg to Los Angeles.
The Mapping with Google course ends June 24. I have no idea why Google limits the time frame for open courses, but it does. If this interests you, sign up soon so you'll have time to finish.
It's actually not necessary to do the whole course. You'll learn just from watching the videos.
You know how I say there are plenty of genealogy education opportunities that are outside the genealogy box? This is one of those examples. So get out there, sign up and start mapping.
