q3 i? Taking the 2018-2019 trend as counterfactual (2.84 years lost in math, 2.25 in Portuguese), nudges prevented 24.2% of Portuguese losses and 7.5% of math losses, with imprecise 90% CIs. → Lichand 2024

Lichand, G., Christen, J., & Van Egeraat, E. (2024). Neglecting students’ socio-emotional skills magnified learning losses during the pandemic. npj Science of Learning. https://doi.org/10.1038/s41539-024-00235-9

q3 · i? · causal · r3

OLS treatment-effect analysis of 2018, 2019 and 2021 State-wide school-level proficiency exams (340 school-grade-subject-year observations pooled). Learning deteriorated tremendously during the pandemic: average proficiency backtracked 2.84 years in math and 2.25 years in Portuguese against the pre-pandemic trend.

"Nudges were able to prevent 24.2% of learning losses in Portuguese (column 2) and 7.5% of those in math (column 3), but these effect sizes are only imprecisely estimated: 90% CI"
