A systematic review and meta-analysis published in Review of Education Research looks at effective academic interventions for pupils with low socio-economic status (SES).
Jens Dietrichson and colleagues included studies that used a treatment–control group design, were performed in Organisation for Economic Cooperation and Development (OECD) and EU countries and measured achievement with standardised tests in maths or reading. The analysis included 101 studies performed between 2000 and 2014, 76% of which were randomised controlled trials.
Positive effect sizes (ES) were reported for many of the interventions. Comparatively large and robust average effect sizes were found for interventions that involved tutoring (ES = +0.36), feedback and progress monitoring (ES = +0.32) and co-operative learning (ES = +0.22). The report points out that, although these effect sizes are not large enough to close the gap between high- and low-SES pupils, they represent a substantial reduction of that gap if targeted towards low-SES students.
