I am broadly interested in the interfaces of instructed additional language (L2) development (second language acquisition) research, pedagogy, and teacher education. This includes language teaching, assessment, language teacher education, and language program design and evaluation. Broadly, my research focuses on three inter-related questions:
Why do students in Anglophone contexts choose (not) to begin and continue studying languages other than English (LOTE)?
How can LOTE language education experiences be optimized (i.e., by improving pedagogy, curriculum, and articulation) and documented/measured (i.e., by improving assessments and other outcome measures)?
How can researchers (better) engage with and share findings with non-researcher stakeholders to improve language education?
My dissertation is a program evaluation study of an undergraduate Spanish program in the United States which uses task-based language teaching (TBLT). I am investigating (a) to what extent the program's pedagogy adheres to the principles of TBLT, (b) students' language learning outcomes, and (c) the connection between pedagogical practices and learning outcomes. My research is supported by generous funding from the National Federation of Modern Language Teachers Association (NFMLTA), Language Learning, and Duolingo.
My full publication list is below (and on my CV). For more information about ongoing research projects, check out Current Projects.
