Increasing demands of accountability and academic readiness across U.S. preschools are often accompanied by decreased play and time outdoors during the school day. The nature preschool movement, grounded in a desire to foster connection to the natural world while also supporting important developmental processes and school readiness, counteracts this trend by simultaneously emphasizing outdoor play and preparing children for success in kindergarten and beyond. This study utilized the "Penn Interactive Peer Play Scale" and "Preschool Learning Behaviors Scale" to quantitatively explore the influence of nature preschools on peer play interactions and learning behavior, both of which contribute to young children's academic readiness. Results indicated that nature preschools may be having a significant positive influence on peer play behaviors in both the preschool and home setting, as well as on all dimensions of learning behaviors. Implications for further research and practice are discussed.
