Only 20 percent of monitored days met the WHO’s PM2.5 guideline—and children’s exposure varied sharply across cities, schools, homes, and commutes.

For just $0.69 per student, a six-session program reached more than 2,000 schools in Indonesia. While it did not raise national exam scores, it strengthened students’ belief in effort, improved self-management habits, and created a more supportive classroom climate—especially in lower-performing schools. It also unexpectedly shifted teachers’ views of failure as a learning opportunity. This episode explores why education programs should be judged by more than test scores and how low-cost interventions can support more equitable classrooms.
