In this paper I propose an agenda for researching language learning motivation "through a small lens", to counteract our tendency in the second language (L2) motivation field to engage with language learning and teaching processes at a rather general level. I argue that by adopting a more sharply focused or contextualized angle of inquiry, we may be able to understand better how motivation connects with specific aspects of second language acquisition (SLA) or particular features of linguistic development. Keeping the empirical focus narrow may also lead to interesting and illuminating analyses of motivation in relation to particular classroom events or to evolving situated interactions among teachers and learners. I propose a number of possible research tasks that might be undertaken by experienced researchers, teacher-researchers or student-researchers wishing to investigate language learning motivation "through a small lens".
