My name is Christy Smith and I am the director of Indiana University Campus Children's Center. The teachers of our program are interested in attending conferences in 2011 & 2012 (and beyond) that focus on Children & Nature. If you know of such conferences in the US please post them here!
The Green Schools Alliance runs a great program called the Student Climate and Conservation Congress each June at the National Conservation Training Center in West Virginia. While this is an amazing program for students grades 9-12, it is also an amazing opportunity for a few teachers who can participate as cohort leaders and learn a lot as well. Check out the website at: http://www.greenschoolsalliance.org/students/student-climate-conser.... I have both sent students and participated as a teacher.
Thanks for mentioning SC3, Stefan. We try to do our part to promote it. Anyone else have recommendations for children and nature conferences?
