From sage on the stage to voice in the void: Exploring the phenomenon of invisibility in virtual learning environments

The shift to online professional development for medical education (PDME) has given rise to a peculiar phenomenon. Individuals participate in online, synchronous seminars with their cameras off and microphones perpetually muted. Teaching to a sea of black boxes challenges PDME facilitators by hindering interaction and diminishing motivation. In this commentary, we explore the implications of this phenomenon and advocate for a multi-institutional study to uncover its causes. By detecting behind-the-camera activities, we aim to identify reasons for disengagement and develop strategies that transform PDME seminars into vibrant spaces of active participation.
