Interfaces Between Second Language Acquisition and Language Testing Research Second Language acquisition(SLA)and language testing (LT)research have largely been viewed as distinct areas of inquiry in applied linguistics.In recent years,however,there has been greater overlap.or interface.between these two areas,and an increasing commonality of interests,both,in tems of the research questions addressed and the empirical approaches taken in dealing wiht these questions. This book provides a fresh look at areas of common interest to both SAL and LT research.and ways in which research in these two areas of applied linguistics can be fruitfully integrated. The volume includes original papers,written around a common theme,dealing with different aspects of the interface betwwen SLA and LT research,by leading researchers in the areas of SLA and LT.This collection thus constitutes a starting point for a continuing and expanding dialogue between SLA and LT researchers.
