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

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.
