Music teaching and learning are socially situated activities. School-university partnerships have the potential to impact preservice teachers’ identities and level of socialization. Thus, a sociologically based belief system for establishing and maintaining school-university partnerships may provide cooperating teachers and university faculty members with purpose and direction for meeting the needs of stakeholders. This article explores the sociological and pedagogical implications of school-university partnerships and illustrates how these underpinnings function in two middle school band collaborations. Specifically, this article examines how partnerships can be viewed through three sociological perspectives, how sociological experiences might impact preservice teachers’ futures, and how policymaking endeavors could impact the strength and continuance of school-university partnerships. What we learn from existing collaborations and how stakeholders respond to this information has the potential to reshape music teaching and learning in our society.
