Global teachers (should) care about education as a whole, as well as their school and their classroom. I just want to iterate that if the person only looks at sharing and learning globally, but cannot connect with those in their classroom or school, I would not consider them a “global teacher”. They just know that we are better when we work together, not just taking, but contributing. They know what they share makes a difference for others, as well as knowing what they learn from others makes a difference for their school and students.
