Introduction: Students’ peer relatedness is vital to their academic achievement and engagement. However, little is known about the mechanisms that can explain such a link in health professions education, especially in interprofessional education (IPE), where interprofessional socialization is promoted. To address the research gap in understanding the social dynamics embedded within IPE and their impact on crucial motivational outcomes, this study examines how peer relatedness (belonging) mediates the link between motivation (both intrinsic and extrinsic) and engagement in IPE. Methods: Data from 841 students enrolled in IPE from Medicine, Nursing, Social Work, Chinese Medicine, Pharmacy, Speech and Hearing Sciences, Clinical Psychology, and Food and Nutritional Science from a university in Hong Kong were used in this study. Intrinsic and extrinsic motivation were collected at baseline, while peer relatedness need satisfaction and engagement and disaffection in IPE were assessed after four weeks. We used a fully latent structural equation model to examine whether peer relatedness mediated the link between motivation and engagement in IPE. Results: Our results indicate that intrinsic motivation at baseline significantly increases engagement and reduces disaffection four weeks later, while extrinsic motivation shows the opposite effect. Crucially, the adaptive role of motivation to engagement was significantly mediated by relatedness from IPE teams. Specifically, the effect of students’ motivation on their engagement/disaffection in IPE can be partially explained by their relatedness within IPE teams. Conclusion: This study underscores the importance of peer relatedness in IPE, highlighting its role in harnessing student motivation to foster student engagement. The findings contribute to a deeper understanding of the psychosocial mechanisms in IPE and highlight the value of collaborative learning environments in fulfilling students’ need for relatedness, thereby fostering

Undergraduate research (UR) is regarded as an impactful instructional practice, but implementing it in the curriculum is challenging. Faculty members' approaches to the design of UR are under-explored due to the scarcity of studies that situate practices in both the curricular contexts and the concept of the research-teaching nexus. This multiple-case study investigated faculty members' approaches to UR in four curricula in two research-intensive universities in Hong Kong. Document review and semi-structured interviews revealed five approaches to UR: project-based, process-based, lab-based, scenario-based, and research community-based approaches. Particularly, the scenario-based and research community-based approaches complemented the current typologies. Another contribution of this study is the identification of nuanced differences in the adoption of the approaches. Faculty members perceiving reciprocal research-teaching nexus at both departmental and personal levels, and viewing UR holistically, tended to connect students with their own research experiences. In contrast, those who only acknowledged the research-teaching nexus at a departmental level were unlikely to create such a connection. Meanwhile, concerns over curricular coherence and ethics were also discussed. The implications include creating a more transparent process of curriculum design and facilitating students' understanding of their contributions to the research community. It would also be useful to engage faculty members more fully in curriculum planning to enhance the coherence of students' research experiences. Copyright © 2023 Taylor & Francis.
