Meta-Analysis Data: Technology-Enhanced Rational Number Learning in K-12

Complete replication materials for a systematic review and meta-analysis examining the effectiveness of technology-enhanced interventions for rational number learning in K-12 education. This dataset includes 12 high-quality experimental studies (N = 1,721 students) conducted across 7 countries between 2017-2025. The random-effects meta-analysis revealed a medium-to-large positive effect (Hedge's g = 0.564, 95% CI [0.468, 0.661]) with negligible heterogeneity (I² = 0%), suggesting consistent benefits across diverse technological platforms and educational contexts.
