The community of traveling families using the globe as their classroom is growing. Welcome to the "world school" revolution

Amanda Dixon was teaching second grade at Kings Center Charter School in Buffalo, New York, while her husband Solomon, 38, was running writing workshops at middle schools around New York state. 

The couple was working long hours to support their three young children, then 4, 2, and 1, when Amanda, 43, thought to herself, "I'm spending all day teaching other people's children and doing all the things that I wanted forever to do with my own children, with other people's children." 

But she didn't see how to make a change — she still loved to teach, and wanted to work. They decided to become "world-schoolers," in which families travel for brief periods, while others open schools and remain on the road for months - or years - at a time to educate their children.
