The Effectiveness of Second Language Pronunciation Instruction: A Meta-Analysis
Lee, Junkyu; Jang, Juhyun; Plonsky, Luke
Applied Linguistics, v36 n3 p345-366 Jul 2015
The goal of this study was to determine the overall effects of pronunciation instruction (PI) as well as the sources and extent of variance in observed effects. Toward this end, a comprehensive search for primary studies was conducted, yielding 86 unique reports testing the effects of PI. Each study was then coded on substantive and methodological features as well as study outcomes (Cohen's "d"). Aggregated results showed a generally large effect for PI ("d" = 0.89 and 0.80 for "N"-weighted within- and between-group contrasts, respectively). In addition, moderator analyses revealed larger effects for (i) longer interventions, (ii) treatments providing feedback, and (iii) more controlled outcome measures. We interpret these and other results with respect to their practical and pedagogical relevance. We also discuss the findings in relation to instructed second language acquisition research generally and in comparison with other reviews of PI (e.g. Saito, 2012). Our conclusion points out areas of PI research in need of further empirical attention and methodological refinement.
