q2 i? Treatment effects on math lay close to the lower range and on Portuguese above the upper range of the 0.12–0.17 s.d. effects of text-message remedial instruction in Botswana, even without instructional content. → Lichand 2024

Evidence¶

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

The article benchmarks its own effect sizes against a second-hand study it cites: remedial instruction via texts and calls in Botswana raised scores by "0.12−0.17 s.d. during the pandemic". The authors note their Portuguese effects exceeded that interval despite no instructional content.

"document that text messages and phone calls with targeted remedial instruction increased test scores in Botswana by 0.12−0.17 s.d. during the pandemic"

Discussion¶

Related Claims¶

• An SMS-based nudge intervention in Cote d'Ivoire did not reduce child labor or raise learning overall, but raised learning and domestic work among children starting with low learning levels — related
• The intervention increased student engagement with remote activities and motivation to return to in-person classes — related
• Message content mattered: loss framing and avoiding social pressure produced significantly larger test-score effects, ruling out experimenter-demand explanations — related
• The nudge intervention had no statistically significant effects on parenting mechanisms of motivation and engagement — related
• Teacher-only and combined parent-teacher nudges showed no statistically significant impacts on learning; point estimates were small and negative for the learning summary and literacy, and near zero for numeracy — related
• SMS nudges targeting socio-emotional skills increased student-level standardized test scores during remote learning, by 0.21 s.d. in Portuguese and 0.19 s.d. on the summary measure — related
