Building upon paradigms of language and languaging practices as "local" phenomena (Canagarajah, 2013; Pennycook, 2010, Pietikäinen & Kelly-Holmes, 2013), this paper narrates a teacher's experience in an undergraduate seminar in applied language studies as an exploration in transdisciplinarity-as-localization. Taught by the author in 2012-2013, the seminar was intended as an introduction to the politics of societal multilingualism as visible in the linguistic landscape of public texts. As such, it relied upon its own geographic and institutional locality, as well as the diverse conceptual moorings and methodologies of linguistic landscape research (e.g., Blommaert, 2013; Shohamy & Gorter, 2009; Trumper-Hecht, 2010) in order to lead students in interpreting the significance of East Asian languages in the San Francisco Bay Area. However, as the paper endeavors to show, the course's own curriculum--and with it, the locus of teacherly authority--was forced to de-localize as the implementation of curricular ideals in practice revealed heterogeneous and expansive orders of meaning.
