• Rethinking Traditional Playgrounds: Temporary Landscape Interventions to Advance Informal Early STEAM Learning in Outdoors

  Education Sciences · 2025-07-24 · 1 citations

  articleOpen access

  Traditional playground settings are often less effective in fostering STEAM (Science, Technology, Engineering, Arts, and Mathematics)-related activities, as fixed play structures tend to restrict the diversity of play behaviors and inhibit children’s ability to engage in self-directed, imaginative exploration. Using a research-through-design methodology, this study investigated how playground design (temporary landscape interventions) influences children’s engagement in informal STEAM learning activities and enhances the STEAM learning affordances of the playground. Conducted at an early learning center in Lubbock, Texas, the research involved GIS-based Environment–Behavior Mapping (E-B Mapping) and video analysis of 21 preschool-age children to compare pre- and post-intervention STEAM learning behaviors. The intervention incorporated fourteen nature-based landscape elements—such as sand and water play areas, sensory gardens, loose parts, art areas, etc.—to enhance affordances for informal STEAM activities. The results showed a marked decrease in passive behaviors and a notable rise in constructive play; collaborative interactions; and STEAM-related activities such as building, hypothesizing, observing, and experimenting. Engagement shifted away from fixed play structures to more diverse and naturalized play settings. The findings underscore the critical role of integrating diverse landscape settings and elements into playgrounds in enriching STEAM learning experiences for young children.

• Tools for Assessing the STEAM Learning Affordances and Quality of Outdoor Learning Environments of Childcare Centers: A Systematic Review

  Early Childhood Education Journal · 2025-04-05

  reviewOpen access

  Abstract Science, technology, engineering, arts and mathematics (STEAM) learning is directly connected with children's cognitive development. Measuring the cognitive advancements of young children is more challenging than that of older ones because young children experience vast variations in the different personal, developmental, and environmental factors affecting their learning behaviors. Also, much learning in the early years is informal in nature, posing added challenges in systematic assessment. There are several assessment tools available for evaluating childcare settings and assessing science learning within the context of the classroom, but none for assessing outdoor learning environments. However, research shows that the outdoor physical environment of early childcare facilities has a long-lasting influence on cognitive development as well as on the quality of STEAM learning for children. There is a critical need for systematic tools to assess formal and informal early STEAM learning outdoor environments to advance both fields of early childhood education and design. This systematic review aims to document all existing tools available for assessing (a) the quality of the childcare outdoor environments and (b) the quality of STEAM learning of children aged 3–5 outside the classroom context, addressing the current lack of reliable and valid assessment measures in this emerging field. The synthesis of information from a selection of 20 studies revealed that STEAM-based outdoor learning at the preschool age is a relatively new topic and that there are no assessment tools or indicators that can assess the available opportunities in the outdoor physical environment and their affordances of STEAM learning activities and activity settings in early childhood environments (e.g., childcare centers, family care homes, or preschools). This deficiency demands more research in the areas of systematic environmental assessments of landscape design indicators in early childhood settings to advance spontaneous STEAM learning behaviors in the early years.

• How Do Nature-Based Outdoor Learning Environments Affect Preschoolers’ STEAM Concept Formation? A Scoping Review

  Education Sciences · 2024-06-11 · 11 citations

  reviewOpen access

  This scoping review examined the impact of nature-based outdoor learning environments on the formation of STEAM (science, technology, engineering, arts, and mathematics) concepts in preschoolers. Preschool age (3–5 years) is the time when physical interaction with surrounding built environments increases, and spontaneous learning from the environment intensifies—making it an ideal age range to promote nature-based informal learning. An outdoor learning environment can influence STEAM concept formations of preschoolers with an intentional design that offers STEAM learning affordances. Despite the rising interest in early STEAM education, there is still limited literature on how the outdoor environment may influence STEAM learning behaviors of preschoolers (3–5 years old). This scoping review intended to evaluate the existing knowledge regarding the physical factors contributing to STEAM learning affordances in an outdoor environment for children aged three to five. The review included studies from the last twenty years. This scoping review was conducted following the criteria outlined in the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR). For this scoping review, 843 citations were discovered across four databases (JSTOR, Scopus, EBSCOhost, and Web of Science), ProQuest, and Google Scholar, and 31 articles were considered eligible for inclusion. The paper synthesized those 31 studies to identify the key STEAM learning behaviors of children and STEAM-activity-supportive settings that may positively influence preschoolers’ STEAM concept development.

• Effects of Childcare Hands-On Gardening on Preschoolers’ (3–5 Years) Physical Activity in Semi-Arid Climate Zone

  International Journal of Environmental Research and Public Health · 2024-04-26 · 2 citations

  articleOpen accessSenior author

  How hands-on gardening impacts behaviors including healthy eating and physical activity during early childhood can be of critical importance for preventing the early onset of obesity. This study investigates how participating in hands-on gardening impacts preschoolers’ (3–5 years old) physical activity (measured by accelerometers) in childcare centers in the semi-arid climate zone. The research was conducted in eight licensed childcare centers located in West Texas with 149 children (n = 149). Four childcare centers in the experimental group received hands-on garden interventions; the other four in the control group did not. In both experimental (intervention) and control (non-intervention) centers, children wore Actigraph GT3X+ accelerometers continuously for 5 days before and for 5 days after intervention (a total of 10 days). Results show that the duration of sedentary behavior of children in the experimental (intervention) group significantly decreased compared to children in the control (non-intervention) group. The finding suggests that the positive effects of childcare hands-on gardening on physical activity extend to semi-arid climate zones where gardening is challenging due to high temperatures and lack of annual rainfall. The research emphasizes the critical need to incorporate hands-on gardening in childcare centers as an obesity prevention strategy nationally in the US and beyond.

• Hands-On Gardening in Childcare Centers to Advance Pre-school-Age Children’s Fruit and Vegetable Liking in Semi-Arid Climate Zone

  Preprints.org · 2024-09-10 · 2 citations

  preprintOpen accessSenior author

  Hands-on gardening is linked with healthy eating behaviors, increased outdoor activities, and overall well-being. Although these positive associations are widely established for adults and school-agers, little evidence can be found on how such relationships may extend to early childhood, especially in the preschool years (3-5 years). One recent study conducted in North Carolina (NC) showed that participating in hands-on gardening significantly increased preschoolers’ accurate identification of fruits and vegetables (FV) and FV consumption compared to children who did not participate in hands-on gardening, but no association was found between participation in hands-on gardening and children’s liking (eating preferences) of FV. FV identification and liking during the early years may lead to lifelong healthy eating behaviors and preferences, making hands-on gardening a critical health intervention in early childhood environments, especially in childcare centers where a majority of the 13 million children in the United States between the ages of 0 and 5 spend most of their waking hours. This research aimed to investigate how hands-on gardening in childcare centers may impact preschoolers’ (3-5 years old) FV knowledge (identification) and liking in a semi-arid climate zone with a high concentration of Hispanic families by conducting experimental research with eight childcare centers and one hundred forty-nine children (n=149) in Lubbock County located in West Texas. Findings showed changes in average liking scores are generally positive in the experiment group of children who participated in hands-on gardening (compared to the control non-gardening group), implying improved liking. The findings indicate that the benefits of hands-on gardening in childcare centers for enhancing healthy eating preferences are evident even in a semi-arid climate zone, where high temperatures and limited rainfall present significant gardening challenges. This research underscores the importance of integrating hands-on gardening into childcare programs, highlighting its potential as an effective obesity prevention strategy not only within the U.S. but also in other regions with similar environmental constraints.

• Gardening in Childcare Centers: A Randomized Controlled Trial Examining the Effects of a Garden Intervention on Physical Activity among Children Aged 3–5 Years in North Carolina

  International Journal of Environmental Research and Public Health · 2023-05-24 · 10 citations

  articleOpen access

  This study examined the effects of a childcare gardening intervention on children’s physical activity (PA). Eligible childcare centers were randomly assigned to: (1) garden intervention (n = 5; year 1); (2) waitlist control (n = 5; control year 1, intervention year 2); or (3) control (n = 5; year 2 only) groups. Across the two-year study, PA was measured for 3 days at four data collection periods using Actigraph GT3X+ accelerometers. The intervention comprised 6 raised fruit and vegetable garden beds and a gardening guide with age-appropriate learning activities. The sample included a total of 321 3–5-year-olds enrolled in childcare centers in Wake County, North Carolina, with n = 293 possessing PA data for at least one time point. The analyses employed repeated measures linear mixed models (SAS v 9.4 PROC MIXED), accounting for clustering of the children within the center and relevant covariates (e.g., cohort, weather, outside days, accelerometer wear). A significant intervention effect was found for MVPA (p < 0.0001) and SED minutes (p = 0.0004), with children at intervention centers acquiring approximately 6 min more MVPA and 14 min less sedentary time each day. The effects were moderated by sex and age, with a stronger impact for boys and the youngest children. The results suggest that childcare gardening has potential as a PA intervention.
