Abstract: In this article, the author examines the effects of an urban environmental education program on children's awareness of their local biophysical environment. She examined changes in environmental awareness among 3rd- and 5th-grade participants in the Open Spaces as Learning Places program in New Haven, Connecticut. Results showed a significant positive effect of the program on students' awareness of the local environment and on their knowledge of environmental concepts. Improvements in environmental knowledge were uncorrelated with the children's socioeconomic status, whereas improvements in local environmental awareness appeared only among students living in high socioeconomic neighborhoods.
