First seen May 16, 2026 · Last updated May 16, 2026

Summary

This study looked at whether a classroom-based program can make children more prosocial—meaning more helpful, cooperative, and kind. Over 2,300 children in grades 5-8 (ages 8-12) took part. Researchers measured changes in behavior, social skills, and classroom climate using surveys and peer nominations. The goal was to see if the program works better than the usual classroom approach.
