Extracurricular Non-Crowding Delivery
Introducing new skill-building programs into public school systems often fails or degrades core academic instruction by displacing scheduled hours reserved for mathematics, science, and literacy.
Picture this
Think of adding an extra passenger to a crowded train car: if you push them into a full row, someone gets kicked out of their seat; but if you place them in an empty vestibule reserved for unstructured waiting, everyone keeps their original seats while gaining extra transport capacity.
What the evidence says
Zero reduction in baseline teaching hours for core subjects occurred, while standardized math scores increased by 0.28 standard deviations (p = 0.008) and Turkish scores increased by 0.13 standard deviations (p = 0.027) without crowding out academic instruction.
- Who
- 106 classrooms across 52 state elementary schools in Istanbul, Turkey.
- How
- Delivery of a 10-to-12-week (minimum 10 sessions, ~2 hours/week) grit program during official 5-hour/week free/extracurricular slots authorized by the Ministry of Education.
What to do
Schedule non-cognitive intervention modules strictly within Ministry-designated discretionary or free play hours to prevent displacement of core academic instructional time.
From the source
"In the absence of any projects, students use the free hours as unstructured playtime, so these projects do not crowd-out any core teaching."
