BACKGROUND: Peer learning in clinical settings is supported in nursing research but has rarely been studied in the context of student midwives at birthing units.

AIM: To create a theoretical model of peer learning in the context of birthing units.

SETTINGS: Four hospitals and maternity units in Stockholm, Sweden.

METHODS: A Straussian approach to grounded theory was applied. Data consisted of interviews with fifteen final-term student midwives and 21 preceptors. Further, six peer learning seminars were held with approximately 200 midwives. At these, data was collected from fourteen preceptors presenting their experiences of working with peer learning.

FINDINGS: The core of the action emerging was the Open dialogue describing the communication between the pair of students, between students-preceptor and students-becoming parents, that developed skills in communication, participation and reduced prestige and hierarchy. It facilitated social interaction and reinforced a dynamic way of learning and teaching midwifery.

CONCLUSIONS: With preparation and a clear framework, peer learning can be used with midwifery students at birthing units. The open dialogue includes the becoming family in decision making and fits in a woman centered care providing support, safety, and participation. The pedagogical benefits are consistent with previous studies on nursing students.
