Science Advances

In a gateway biology course, students were randomized to a 15-minute values-affirmation or control writing task in week three. Among 226 students with baseline and end data, treated students reported about 29.2 percent more friends and were 11.7 percentage points more likely to enroll in the next course.

How medical students reshape support networks during the transition to clerkships

Medical Education

Eight medical students drew ego-network maps within two weeks of starting clerkships and again four months later, then explained the changes in interviews. Their combined alters shifted from 128 to 134 as students deliberately created, retained, and dissolved ties for emotional and instrumental support.

International Journal of Computer-Supported Collaborative Learning

Across 12 university-course iterations, the study showed that network construction choices affect the robustness of centrality measures, with multigraph degree measures most consistent for participation and performance.

Linking engagement and performance through longitudinal physics classroom networks

Physical Review Physics Education Research

Longitudinal interaction surveys in a two-semester Modeling Instruction physics sequence tracked classroom networks at four exam points per term. Three of four centrality measures predicted later performance after prior GPA controls, and closeness added up to 28 percent explained variance as the community developed.

How rotating trainee-doctor networks support different kinds of workplace learning

BMJ Open

Across five rotational hospital teams over 24 months, 39 trainee doctors completed network surveys and a separate set of 15 trainees were interviewed. Advice and emulation ties differed across clinical-technical, patient-centered, and work-organization learning, showing that one generic network misses domain-specific pathways.

Online problem-based learning interaction networks and medical student performance

Mohammed Saqr, Hani Alamro

BMC Medical Education

A study of 135 students and 15 tutors across 15 problem-based learning groups analyzed 2,620 online interactions, 89 percent of them student-to-student. Out-degree and tutor interaction had small positive correlations with performance, showing useful relational signals without supporting causal ranking.
