Environmental education for young children has great potential for fostering the skills, values, and dispositions that support sustainability. While North American guidelines emphasize the importance of using the natural world for open-ended exploration, discovery, and play, this approach has been criticized for lacking the transformative power necessary for meaningfully contributing to sustainability issues. Four pilot studies were conducted exploring the influence of nature play in the context of nature preschools on children's curiosity, executive function skills, creative thinking, and resilience. These studies used established quantitative instruments to measure growth in these constructs among nature preschool participants, comparing this growth with participants in high quality, play-based, non-nature preschools. The results suggest a positive contribution of nature play, with greater levels of curiosity, creative thinking, and resilience than what was observed in the non-nature preschool participants, and executive function skills similar to the non-nature preschool participants and exceeding national norms. Collectively, these pilot studies suggest the potential contribution of nature play in the context of education for sustainability.

This study examined the relations between receptive language development and other developmental domains of preschoolers from low-income families, through an inter-cultural perspective involving the United States and Turkey. A total of 471 children and their caregivers participated in Turkey, while 287 participated in the United States. Children's development was assessed using the Ages and Stages Questionnaire for both samples. Different versions of the Peabody Picture Vocabulary Test were used for Turkish and US samples, to measure receptive language development. Results revealed similar patterns, with some differences, between the two countries. Receptive language predicted only communication and personal–social scales in the Turkish sample, while the US children's receptive language skills were associated with communication, problem solving, personal–social, and fine and gross motor development scales. These results were discussed in the context of each country, and the comparative conclusions contribute to the extant literature by illustrating the importance of language for three domains.
