This article draws lessons from the Playful Learning Landscapes (PLL) initiative, which marries the learning sciences with urban revitalization to craft carefully planned playful learning experiences. Results of this meta-analysis provide initial evidence that PLL installations demonstrate large effects on caregiver behavior and caregiver-child interaction, and medium effects on child behavior, in comparison to either control sites or pre-PLL installation. These findings are encouraging and suggest that continued investment in creating and evaluating new PLL installations is appropriate.
