“…High-quality classrooms that include social-emotional and behavioral support emphasize adult-led interactions, including following children's interests, joining play, engaging in rich conversational exchanges, and building relationships with families (Powell, Diamond, Burchinal, & Koehler, 2010). Classroom structure can support positive interactions and child engagement; teachers who implement strategic environmental arrangements increase the likelihood of child engagement and communicative behaviors (Davis & Fox, 1999; Kaiser, Ostrosky, & Alpert, 1993). Environmental strategies include having sufficient materials rotated to maintain child interest and support specific language use, arranging the daily schedule to meet children's changing developmental needs, and arranging the physical environment to support social play between children and frequent engagement with adults one to one or in small groups (Hemmeter, Ostrosky, & Fox, 2021).…”
