Some of what they discovered is what Fieldguides has been doing for the past 30 years! Experiential Learning is the foundation of what we do. By immersing the kids in the outdoor environment and giving them the time to explore and be exposed to the wonders of nature (both with a focused activity and in less structured time), we Foster Curiosity. Our group games and unique family-camping style in which everyone works together learning and doing chores are designed to Increase Collaboration and Teamwork among the students.
I can attest to it NSF, your findings are sound!
