At this moment, fully online language courses are being taught all around the globe. In addition, blended courses offer an integration of online and live instructional experiences. This study examines who is instructing online language courses and what they point to as additive and advantageous to their online language teaching development. We set out to survey higher education faculty as to how they developed their knowledge and practices. Through an online survey and follow-up synchronous interviews, we asked practicing online language educators about the sources of their expertise. The resulting dataset has much to inform professional development and instructional support generally, as well as broader research and educator communities regarding the ongoing, open-ended, peer-supported, and social nature of this kind of educator learning. As more language educators move their instruction online, the question of how to maximize the pedagogical potential of the new medium can best be addressed by those who have successfully made and embraced this move.
