The success of camp experiences relies heavily on the unique culture each camp can create and maintain through the season. Camps are renown for creating cultures where campers and staff feel like they belong, they are safe to try new skills and identities, and they are unconditionally cared for. This isn’t always ‘easy’ work. The concept of “mattering” (indorsed by Flett, 2018) offers a conceptual “backbone” for creating psycho-socially healthy, meaningful and inclusive camp cultures. In this workshop, Mandi (camp researcher), Ashley (Exec Director of Mini U) and Jessy-Stephanie (student researcher and first-time camp participant) will share what they’ve learned from their “Mattering at Mini U” study and facilitate camp leaders in activities that help them intentionally develop and maintain cultures of mattering at their own camps.
