Across countries, there are important differences related to the goals, organization, and educational philosophies of care provided to young children prior to formal schooling. Those differences are likely reflected in the classroom practices and teacher-child interactions within a country’s early childhood education and care (ECEC) classrooms. This study aims to evaluate the within-country relevance of two classroom observation measures primarily based on a behavioral count approach focused on teacher and child behaviors; and to examine preschool practices in Sweden, Portugal, and the U.S., as they reflect each country’s ECEC goals, organization, and educational philosophies. Participants are 78 preschool settings in Sweden, 42 in Portugal, and 168 in the U.S. Results show that the measures targeted culturally-relevant behaviors and provided inter-rater reliability for the behavior count variables in the three countries. Future collaborations may address additional culturally-specific variables. The behavioral descriptions yielded by combining behavioral counts of the measures are analyzed by researchers from the relevant country for insights to the country’s values related to early childhood as well as current debates regarding care for children. Measures that provide comprehensive descriptions of classroom settings and apply minimal external or comparative value judgments on the behaviors observed are of practical utility for collaborative international work.

How preschool teachers and children spend their time in preschool sets the stage for child engagement and learning. To describe characteristics of environments and activities and to compare child engagement in indoor and outdoor free play, systematic observations of children and teachers were performed in 78 Swedish preschool units. Results showed that indoor and outdoor free play were the main activity settings. Children interacted as much with other children as with teachers. The content focus was dominated by non-pretend play, construction, art and music, followed by pretend play and academic contents. Child engagement was significantly higher in free play indoors compared to outdoors. Teachers engaged in varied tasks, but their central task was managing. Teachers were typically in proximity to small groups of children, or by themselves, and mostly talked to or listened to a single child. Findings are discussed in relation to the preschool curriculum and future research needs.

The participation of all children in preschool activities is the main outcome of inclusive Early Childhood Education and Care (ECEC). The current study used the Child Observation in Preschool (COP) to explore the observed participation patterns in the free play of a sample of 3-5-year-old Swedish preschool children (N = 453), and to examine the characteristics of the resulting clusters in terms of child and preschool unit characteristics. Based on a series of hierarchical and K-means cluster analyses, we identified eight distinct and meaningful clusters that could be ranked from very high to very low observed participation. Four of the clusters indicated average-to-very high observed participation. Two clusters indicated low-to-very low observed participation. The cluster displaying low observed participation had high proximity to a small group including teachers. On average, children in this cluster came from preschool units with significantly more second language learners. The cluster displaying a very low observed participation had low proximity to a small group including teachers. On average, children in this cluster were significantly more often second language learners, and the children came from units with a significantly higher number of resource staff. No significant differences appeared in the number of children with special educational needs across the clusters, although tendencies emerged. The results imply that the children in this sample had a varied degree of observed participation. Two clusters of children appeared to have difficulties in participating in free play activities where second language learners and children from preschool units with more second language learners were more common. Preschool teachers need to identify children who participate less in preschool activities and who might benefit from more teacher proximity. Teachers also need to reflect on how their proximity impacts the participation of children differently and on the type of support they provide when being close to the children.
