Unadapted Resource Input Ineffectiveness
Meta-AnalysisJournal Article
Providing additional physical inputs or financial resources to underperforming schools fails to improve student test scores when the material is not adapted to student learning levels.
Picture this
Adding new textbooks or supplies to a classroom where students cannot read basic letters is like giving advanced sheet music to someone who cannot read basic notes; without foundational understanding, additional materials remain completely unusable.
What the evidence says
Providing unadapted textbooks, flip charts, or extra formal teachers produced zero statistically significant improvements (0.00 standard deviation) in average student test scores.
- Who was studied
- Synthesis of multiple randomized evaluations across primary school contexts in developing nations (e.g., Kenya, India).
- How
- Systematic review of randomized controlled trials evaluating physical and personnel inputs (textbooks, flip charts, teacher headcount, meals, deworming).
What to do
Audit educational spending to ensure additional physical or human resources directly target baseline learning deficits rather than expanding standard unadapted curriculum inputs.
From the source
"Worse still, a number of rigorous, randomized evaluations have confirmed that spending more on resources like textbooks [Glewwe, Kremer, and Moulin 2002], flip charts [Glewwe et al. 2004], or additional teachers [Banerjee, Jacob, and Kremer 2004] has no impact on children's test scores"
