Does class size in first grade relate to children's academic and social performance or observed classroom processes?

This study evaluated the extent to which first-grade class size predicted child outcomes and observed classroom processes for 651 children (in separate classrooms). Analyses examined observed child-adult ratios and teacher-reported class sizes. Smaller classrooms showed higher quality instructional and emotional support, although children were somewhat less likely to be engaged. Teachers in smaller classes rated typical children in those classes as more socially skilled and as showing less externalizing behavior and reported more closeness toward them. Children in smaller classes performed better on literacy skills. Larger classrooms showed more group activities directed by the teacher, teachers and children interacted more often, and children were more often engaged. Lower class sizes were not of more benefit (or harm) as a function of the childs family income. First-grade class size in the range typical of present-day classrooms in the United States predicts classroom social and instructional processes as well as relative changes in social and literacy outcomes from kindergarten to first grade.

Child care improvement on a shoestring: evaluating a low-cost approach to improving the availability of quality child care.

The Philadelphia Early Childhood Collaborative (the Collaborative) was designed to improve the quality of child care by increasing coordination among organizations that locally deliver professional resources to child care providers. The evaluation examined the implementation of the Collaborative, utilization of its services, and the impact of service use on child care quality. Child care providers reported gains in their professional knowledge and behavior from using Collaborative resources and rated the resources highly. No long-term effects on provider behavior, knowledge, or attitudes were observed. Although the original organizations were able to function collaboratively and Collaborative services were widely used, more intensive interventions may be required to change the availability of quality child care.
