quality review

Evaluating research designs plays a pivotal role in promoting principled Mixed Methods Research (MMR). Although the quality of mixed methods designs has been among the most debated topics, scant attention has been drawn to the investigation of Applied Linguistics (AL) Islamic World Science Citation Center (ISC) journals. Informed by this gap, the present exploratory sequential mixed methods study aimed at analyzing the research designs, tools of data collection, and purposes of 303 MMR articles published in 12 leading ISC journals. This involved a qualitative content analysis using a code sheet based on established MMR typologies, followed by a quantitative frequency analysis to determine the prevalence of these coded categories. The findings indicated that sequential designs were more frequently used in the corpus. Moreover, as regards the tools of data collection, questionnaires and interviews were the most commonly utilized ones. Finally, exploration purpose was the prime purpose opted for by the researchers in the study corpus. The study highlights the importance of conducting principled MMR through the reconceptualization of designs from method to methodology level. It further argues for a systemic view of MMR in which there is a cyclic interaction among fully integrated stages of an MMR design. The implications of the findings are discussed throughout the paper.
