The CLAVIER (Connected Learning And Virtual Intercultural Exchange Research) network grew rhizomatically as a result of open practice (Blyth, 2019), which is central to the CLAVIER approach. Informed by the field of Computer-Mediated Communication (CMC), the network has provided a safe space to experiment with the development and implementation of open badges to support sustained participation in Virtual Exchanges (VEs). This case study describes the rationale for CLAVIER's open badge framework and its links with the Erasmus+ VE (E+VE) badges.
