The role of learning activities and social presence in synchronous hybrid classrooms: results from a natural experiment

Abstract

ABSTRACT The synchronous hybrid classroom (SHC) combines on-site and remote learners simultaneously. This study aims to investigate how participation mode (on-site vs. remote) affects students’ perceived learning in a SHC, examining social presence as a mediator. A second aim explores how different learning activity types along the ICAP framework influence students’ perceived learning across both groups, again considering social presence as a potential mediator. A natural experiment was conducted with 241 vocational secondary school students regularly participating in a SHC, either on-site (n = 136) or remotely (n = 105). Results showed that participation mode influenced students’ perceived learning indirectly through social presence. Remote participants perceived their social presence as lower and learning less effective than on-site participants. Interactive learning activities were most frequently used in this SHC implementation. The mediating effect of social presence was particularly strong for active/interactive activities on-site and passive/interactive ones remotely. This study contributes to theory by unravelling the complex interplay of the pedagogical design of a SHC and students’ learning experiences, highlighting the critical role of fostering social presence to optimise learning outcomes in SHC. Furthermore, it underscores the practical necessity for robust technological infrastructure and professional development support for teachers to enhance the efficacy of SHC settings.
