Online or offline – Does it matter?

Policymakers and scholars are scaling up online professional development programmes for teachers. We studied how in-service teachers in Norway perceived their learning outcomes for professional development programmes conducted either as campus-based or online courses. Based on survey data, we found teachers studying online and in campus-based settings have relatively similar perceptions of the learning outcomes. This changes when indicators of collaboration and support from teachers are controlled for, suggesting that these factors are more strongly related to learning outcomes for those in campus-based studies than those in online studies. Our findings contribute new insights on how perceived learning outcomes influence study formats and how social dimensions may impact professional development.
