"Washback" refers to the influence of language testing on teaching and learning. This volume, at the important intersection of language testing and teaching practices, presents theoretical, methodological, and practical guidance for current and future washback studies. It provides an overview of the complexity of washback and the various contextual factors entangled within testing, teaching, and learning and presents empirical studies from around the world that offer insights into the effects of washback in specific educational contexts and models of research on which future studies can be based. "Washback in Language Testing: Research Contexts and Methods" is a valuable resource for those who are interested in the application of findings to actual teaching and learning situations or conduct washback research in their own contexts, including educational and psychological testing experts, alternative assessment people in all fields, and policy- and decision-makers in educational and testing organizations.
