There are those who maintain that SLA must be applicable to L2 pedagogy: a view based on the argument that because SLA is a subfield of applied linguistics, it should have direct relevance to L2 teaching. Others take the view that not all areas of SLA research need to be relevant to L2 pedagogy -only the more 'applied' areas. While I would agree that much of the work in SLA should be applicable to L2 pedagogy, particularly research on instructed SLA, my presentation takes a different perspective on the SLA/L2 pedagogy interface. It focuses on MISAPPLICATIONS of SLA theory and research to L2 pedagogy. I argue that the applicability of SLA research for L2 instruction requires a careful consideration of context and that specific SLA constructs -even those considered to be important within instructed SLA -may not have direct RELEVANCE to L2 pedagogy. Three areas of SLA research that I will discuss with respect to misapplication and relevance are: the role of instruction in SLA, the role of age in SLA, and the nature of and distinction between implicit and explicit L2 knowledge.
