From the abstract: "The goal of this study was to understand the relationship between child care quality and children's engagement behavior. Seventy-eight toddlers from 17 child care centers were individually observed to determine the percentage of time they spent in sophisticated, unsophisticated, or differentiated engagement, or focused attention. The percentage of group engagement in classroom activities was recorded as well. Program quality ratings consisted of measures of the classroom environments, including the teachers. All the contextual quality measures but 1 were associated with unsophisticated engagement. Only global classroom quality was related to sophisticated engagement. The percentage of toddlers engaged in activities was associated with other program quality measures but not with observations of individual child engagement conducted at different times."
