“…While personable and desirable, the approaches suggested are considerably resource intensive, given that teachers would have to record their discussions with each student as a form of tracking, without which they might not be conscious of progress made by each student. In light of this, the Moral Reasoning Questionnaire (MRQ) was developed upon an operational definition of moral reasoning proffered by Lim & Chapman (2021a) for use in Singapore schools on a large-scale basis for students aged between 12 and 18 (between grade 7 and 12), after an extensive review of established instruments found concerns with content appropriateness and group administrability (Lim & Chapman, 2021b). Based on critical stages recommended by the Standards for Educational and Psychological Testing (American Educational Research Association, American Psychological Association & National Council on Measurement in Education [AERA, APA & NCME], 2014), the MRQ was preliminarily validated in part on a classic test theory (CTT) factor analytic approach to establish its factorial structure, and the analyses found both quantitative and qualitative support for validity evidence and the reliability of the MRQ (Lim & Chapman, 2021c); quantitative support was established via the factor analytic approach (i.e., exploratory factor analysis followed by confirmatory factor analysis) and parallel analysis, while qualitative support was established via evidence from: (1) content appropriateness where an expert panel critique the initial item pool, and (2) response processes, where the items were validated through engaging five students, within the age range by which the MRQ was intended, in cognitive interviews (Willis, 2017).…”
