Mixed-methods research proficiency for applied linguists: a PLS-path modelling approach

Since the 2010s, the appeal for utilizing mixed methods research in applied linguistics and its related strands has been expanding. However, recent text-based studies highlighted some deficiencies in planning and practicing MMR. As such, the current study, adhering to Guetterman’s (2015) framework, examined applied linguistics’ mixed methods research proficiency, targeting 175 applied linguists who published in top-tier journals. A mixed methods proficiency questionnaire was created to examine applied linguists’ proficiency (i.e., knowledge, experience, ability, and skill) of the mixed methods research movement. Our results revealed that applied linguists were professionally knowledgeable about the foundations of MMR research, the rationale of MMR, MMR questions, and designs. However, they need to improve their knowledge of mixed methods’ integration, transparency, and quality. The results further revealed that despite the moderate skillfulness of applied linguists in MMR studies, they should boost their MMR skill repertoire in MMR quality features such as integration, validity, and meta-inferencing. Our PLS-path findings support Guetterman’s proficiency model, providing a new pedagogical culture in MMR studies wherein exposure to experience or professionalism in MMR has played a contributory role in enhancing MMR knowledge and skills. Accordingly, applied linguists might be able to shift their MMR orientation away from eclecticism to principlism and innovatism.
