Research visibility and speaker ethos: a comparative study of researcher identity in 3MT presentations and research group videos
Résumé
This study analyses researcher identity projection in two digitally-mediated genres, both addressed to non-specialist audiences: Three Minute Thesis presentations (3MTs) by doctoral students, and Research Group Videos (RGVs) produced by researchers in university laboratories. Adopting a discursive, socially constructed view of identity, we compare the researchers' identities by considering three dimensions: level of researcher expertise (novice researchers in 3MTs vs senior researchers in RGVs), disciplinary area (STEMM vs SSH), and the different verbal and non-verbal affordances available for identity projection. Results show that in both genres the researchers' credibility or ethos is founded on non-technical arguments (social applications, practical outcomes) in a concern for proximity with the lay audiences. However, there are also numerous differences in the identities projected in the two genres, particularly in terms of the level of researcher expertise (novice vs senior). Disciplinary differences in the identities performed in STEMM and SSH are also observed, reflecting each discipline’s epistemic culture.
