Introduction: In clinical health professions education, portfolios, assignments and assessment standards are used to enhance learning. When these tools fulfill a bridging function between school and practice, they can be considered ‘boundary objects’. In the clinical setting, these tools may be experienced as time-consuming and lacking value. This study aimed to investigate the barriers to the integration of boundary objects for learning and assessment from a Cultural-Historical Activity Theory (CHAT) perspective in clinical nursing education.

Methods: Nineteen interviews and five observations were conducted with team leads, clinical educators, supervisors, students, and teachers to obtain insight into intentions and use of boundary objects for learning and assessment. Boundary objects (assessment standards, assignments, feedback/reflection/patient care/development plan templates) were collected. The data collection and thematic analysis were guided by CHAT.

Results: Barriers to the integration of boundary objects included: a) conflicting requirements in clinical competency monitoring and assessment, b) different application of analytical skills, and c) incomplete integration of boundary objects for self-regulated learning into supervision practice. These barriers were amplified by the simultaneous use of boundary objects for learning and assessment. Underlying contradictions included different objectives between school and practice, and tensions between the distribution of labor in the clinical setting and school’s rules.

Discussion: School and practice have both convergent and divergent priorities around students’ clinical learning. Boundary objects can promote continuity in learning and increase students’ understanding of clinical practice. However, effective integration requires for flexible rules that allow for collaborative learning around patient care.
