Interpreting Effect Sizes in L2 Research

Plonsky, L. and Oswald, F.L. (2014), How Big Is “Big”? Interpreting Effect Sizes in L2 Research. Language Learning, 64: 878-912. doi:10.1111/lang.12079 Abstract The calculation and use of effect sizes—such as d for mean differences and r for correlations—has increased dramatically in second language (L2) research in the last decade. Interpretations of these effects, however, have been rare and, when … Read more

Our understanding of language will undoubtedly benefit from more focus on language in its natural habitat: conversation (e.g., Du Bois et al., … Read more
