Data for three collaboration networks were collected in four secondary schools in Switzerland in 2018 on teachers exploring new ideas on teaching (teaching improvement), teamwork (team improvement), and school organization (organizational improvement). Using social network analysis, we examined to what extent the collaboration networks overlap, how network structures differ, and what factors explain these differences. The results revealed substantial differences between collaboration in the three areas. This suggests that future research should examine collaboration from a multidimensional network perspective.enTeacher collaborationSchool improvementSocial network analysisExponential random graph model (ERGM)370 - Erziehung, Schul- und Bildungswesen01A - Beitrag in wissenschaftlicher Zeitschrift1-17
