In response to the interruption of all levels of education following COVID-19, we start by underlining the difference between emergency remote teaching and online learning. Next, we inquire into the question of presence in physical and virtual classrooms, and offer a discussion of presence as "being-here-now," a "movement toward becoming," and as gelassenheit or "releasement toward things." We highlight the materiality of communication, and the performative production and transformation of the classroom space. Finally, we illustrate how performative writing enhances the sense of being-here-now, and facilitates the co-inhabiting of online learning spaces that lack co-presence of bodies in the same physical environment.
