The use of digital tools like computers and tablets in institutional learning arenas give rise to forms of flexibility where time and space boundaries become diffuse. Online learning sites are understood as being crucial today, especially in large parts of the Global North, where anyone anywhere potentially can become a student and have access to educational opportunities. This study focuses on the analysis of recorded sessions, part of an "Italian for (adult) beginners" online course. Our interests relate to accounting for how students negotiate different language varieties, including modalities, and how communication in virtual learning settings enables both flexible participation trajectories and identity positions in and across the boundaries of time and space. The sociocultural and dialogical analyses here are framed in terms of fluidity of "glocal" positions and (trans)languaging that emerge in and across time and space in Technology Mediated Communication. Our findings suggest that online environments support meaning-making where it is possible to identify alternative ways of (co)constructing and mediating learning. Such hybridity as well as the performative character of learning and identity display have important implications for online glocal communities.
