The most challenging issue in education today is the transformation of the teacher's role:
There are more than two million teachers in the United States. And that doesn't count religious educators and youth ministers in churches, temples and synagogues, Scout leaders, afterschool organizers and coaches for a plethora of sports. All have one thing in common — a commitment, even a passion to help the next generation(s) gain the skills they will need to be whole and healthy persons, informed and active citizens, knowledgeable workers and loving adults and parents of future generations.
In the 21st century, students come to school with skills, information and "prior knowledge" that were never available to earlier generations. Preparing teachers for working with students who have thousands of hours of "screen" time, mastered dozens of videogames before kindergarten and become masters of smartphones is an enormous challenge to the many structures that support the preparation of teachers and leaders for both the formal US educational system and informal community-based programs.
