Beyond the average: a systematic review and meta-analysis of differentiated instruction for diverse English learners

A systematic review and meta-analysis of 45 studies across 18 countries indicates that differentiated instruction generally benefits diverse English learners. However, the effectiveness of this pedagogical approach varies significantly depending on the context of its implementation, including the specific 'where, how, and with whom' it is applied, suggesting that its impact is not universally consistent despite an overall positive average effect.

This research is strategically important because it moves beyond aggregate positive findings to highlight the contextual variability of educational interventions. Understanding these nuances is critical for optimizing resource allocation and tailoring pedagogical strategies to maximize learner outcomes, rather than adopting a one-size-fits-all approach.

Differentiated instruction generally supports diverse English learners, based on an analysis of 56 effect sizes from 45 studies.
