A Culturally Responsive Digital Differentiated Learning framework is associated with greater engagement and narrower learning disparities in higher education: a quasi-experimental mixed-methods study

Abstract

Engagement and achievement gaps in higher education remain persistent, especially for students from lower socioeconomic and minority cultural backgrounds in digital learning environments. This study examined whether participation in LMS-based courses implementing a Culturally Responsive Digital Differentiated Learning (CR-DDL) Framework was associated with greater improvements in student engagement and learning outcomes and with narrower observed engagement disparities compared with standard LMS-based instruction. An explanatory sequential mixed-methods design was used with 252 undergraduates in public health and agrotechnology programmes at three Indonesian institutions, comparing CR-DDL courses ( n  = 129) with standard LMS-based courses ( n  = 123). Quantitative data included pre- and post-intervention Higher Education Student Engagement Scale scores, LMS-derived behavioural indicators, and final course scores. Outcomes were analysed using linear mixed-effects models with a random intercept for course to account for the clustering of students within the six participating course clusters. Eighteen students also participated in semi-structured interviews to provide contextual insight into their learning experiences. The CR-DDL group demonstrated a larger increase in total engagement than the comparison group (mean change, +0.52 vs. + 0.13; group × time estimate = 0.31, SE = 0.07, approximate Wald 95% CI 0.17–0.45, p  < 0.001). Greater increases were also observed in LMS-based participation. After adjustment for prior-semester GPA and course-level clustering, CR-DDL participation was associated with a 3.41-point higher final course score on the 0–100 reporting scale (SE = 1.12, approximate Wald 95% CI 1.21–5.61, p  = 0.003). Lower-SES students in CR-DDL courses showed larger descriptive engagement gains than their counterparts in comparison courses. Because the formal group × time × SES interaction could not be verified from the currently reported summary results, the SES findings are interpreted as exploratory subgroup patterns rather than definitive evidence of effect modification. Documented interview excerpts provided limited contextual insight into students’ experiences but were not treated as independently reproducible qualitative evidence. The quantitative findings provide evidence that CR-DDL was associated with improved engagement, LMS participation, and course performance and with a narrowing of observed engagement disparities. The available qualitative material provides limited contextual insight into students’ experiences but should be interpreted cautiously because complete original qualitative records are currently unavailable.
