The case studies examined how three preservice teachers within a Master of Arts in Teaching program at a small, private university negotiated meaning around an educational practice-collaborative action research. Preservice teachers must negotiate multiple, and often competing, internal and external discourses as they sort out what educational practices, policies, organizational structures to accept or reject as presented in the teacher education program. This negotiation is a dynamic, contextual, unique meaning-making process that extends, redirects, dismisses, reinterprets, modifies, or confirms prior beliefs (Wenger, 1998).
