It is well documented that the integration of inquiry-based learning (IBL) and problem-based learning (PBL) methodologies in initial teacher education (ITE) provides opportunities to enhance pre-service teachers' research skills. However, few studies articulate the processes by which teacher educators implement and sustain these approaches in cross-institutional collaboration. This paper explores the journey of two teacher educators and their pre-service teachers, within a cross-institutional study on curriculum and assessment, problematising aspects of the longitudinal application of IBL and PBL methodologies. Dialogical reflections by the teacher educators and a critical friend, along with student questionnaires, were analysed in this three-year action research study. Findings demonstrate an increase in pre-service teachers' research skills but limited transferability of learning to teaching. The papers' central contribution proposes that as ITE reconfiguration evolves programmes can capitalise upon cross-institutional professional collaborations between teacher educators. Collaborative IBL and PBL learning spaces can be creatively explored to enhance transferability, developing pre-service teachers as researchers, a core element of initial teacher education programme accreditation.
