Mixed-methods research in applied linguistics: Charting the progress through the second decade of the twenty-first century

Abstract This review of recent scholarship (RRS) paper is a follow-up of the first, published in this journal in 2014. For this RRS paper, we identified and included 304 mixed-methods research (MMR) papers published in 20 top-tier applied linguistics (AL) journals. We used a six-pronged quality and transparency framework to review and analyze the MMR studies, drawing on six quality frameworks and transparency discussions in the MMR literature. Using the quality and transparency framework, we report on: (1) which sources AL MMR researchers use to frame their studies, (2) how explicitly they explain the purpose and design structure of the MMR studies, (3) how transparently they describe method features (sampling procedures, data sources, and data analysis), and (4) how they integrate quantitative and qualitative data and analyses and construct meta-inferences. The results of the analyses will be reported and will show how MMR has developed and is represented in the published articles in the second decade of the twenty-first century. The discussion of the results will also highlight the areas future AL MMR researchers need to consider to make their studies and reports more rigorous and transparent.
