Duoethnography is an emerging methodology in English language teaching (ELT)/applied linguistics where two or more participants critically examine a shared phenomenon or experience as a way to challenge assumptions and develop new understandings of critical events (Lowe & Lawrence, 2020). It is a flexible tool with an emphasis on interaction, both between people, and people and various physical or digital artefacts (e.g., documents, academic literature). In this paper, we outline our duoethnography on our experience with the Certificate for English Language Teaching to Adults (CELTA) with a focus on how academic literature and social media pervaded our inquiry. We highlight how academic articles and social media were used as artefacts in our study and how their role as "coparticipants" enhanced our investigation.
