In my school, we have used the Circle of Courage woven throughout everything we teach. It was developed originally as a program to help at-risk First Nation students to avoid issues like alcoholism, drop-outs, ect. The main tenets are Belonging; Mastery; Independence; and Generosity. It was found that those students most connected to these tenets had more success. This site offers more information about the Circle of Courage and resources.
