Language Teaching Research Quarterly

This article describes a new questionnaire, the “Diagnostic Inventory for Self-Regulated Language Learning” (DISLL), for assessing self-regulated learning strategies of students of English as an additional language. We discuss self-regulated learning models, evaluate existing questionnaires for assessing language learners’ self-regulated strategy use, and present a rationale for the DISLL. We explain Zimmerman’s (2000) three-phase model, adapted with simplified phase names: planning, doing, and reflecting. Every DISLL phase starts with a brief scenario to help learners judge how often they employ each strategy in that phase. Already completed are a review of the DISLL 1.0 by 18 international researchers, the step-by-step creation of the DISLL 1.1, and the profiling of vocabulary in the DISLL 1.1 to ensure the simplicity necessary for intermediate-level learners. We present an argument-based validation framework, to be supported by piloting the DISLL 1.2 in Iran, Saudi Arabia, Spain, and Poland and even broader piloting of the DISLL 1.3. Statistical analyses will involve quantitative methods, e.g., exploratory and confirmatory factor analysis, reliability analysis, and confirmatory composite analysis. At least one site will also use qualitative think-aloud protocols. The DISLL will be released into the public domain for free use after version 1.3.
