The Highscope Foundation is the program that I chose to become a member of and receive newsletters and update about recent information about early childhood. Highscope provides certified trainings for teacher to ensure that they can providing children with the opportunities to make chooses, problem solve, learn from their interest and explore. Highscope developed the measuring tool called the COR that is use in early childhood classrooms around the world.  

One of the issues that are addressed in a news letter is Conflict Resolution. High scope talks about how Preschoolers are not too young to develop the skills to conflict resolution. When children are guided into learning how to express themselves and their feelings into words, they learn how to resolve situations without violence. This is only one of the great issues that Highscope support learning and active environments for teachers and children. Check them out. I believe that you will find this organization very informative.
