ABSTRACT
Recent research suggests that Head Start may be differentially effective in improving low-income children's early language and literacy skills based on a number of individual- and family-level characteristics. Using data from the Head Start Impact Study (n = 3503; 50% male, 63% treatment group), the present study extends this work to consider program impact variation based on centers' location in urban versus rural communities. Results indicate that Head Start is more effective in increasing children's receptive vocabulary (as measured by the PPVT) in urban areas and their oral comprehension (as measured by the Woodcock-Johnson Oral Comprehension task) in rural areas. Additional analyses suggest that related characteristics of the center - including concentration of dual language learners and provision of transportation services - may underlie these associations. Implications for research on program evaluation and policy are discussed.
ABSTRACT
We assessed impacts on classroom quality and on 5 child language and behavioral outcomes of a 2-year teacher professional-development program for publicly funded prekindergarten and kindergarten in Chile. This cluster-randomized trial included 64 schools (child N = 1,876). The program incorporated workshops and in-classroom coaching. We found moderate to large positive impacts on observed emotional and instructional support as well as classroom organization in prekindergarten classrooms after 1 year of the program. After 2 years of the program, moderate positive impacts were observed on emotional support and classroom organization. No significant program impacts on child outcomes were detected at posttest (1 marginal effect, an increase in a composite of self-regulation and low problem behaviors, was observed). Professional development for preschool teachers in Chile can improve classroom quality. More intensive curricular approaches are needed for these improvements to translate into effects on children.
