This paper analyzes variation in the medium-term effects of the oversubscribed Boston Public Schools prekindergarten program. Prekindergarten gains persisted if kids applied to and won a seat in a higher-quality elementary school.
A Scan of the Literature and Current Approaches
Low-income and minority children suffer disproportionately from asthma. This review examines efforts to improve education and self-management, remediate asthma “triggers” at home, and improve health care provider practice. It concludes that asthma management education; proper, sustained medication regimes; cost-effective, replicable programs; and steady funding are all critical for addressing health disparities.
Using data from the Head Start Impact Study, this paper examines variation in Head Start effects across individual children, policy-relevant subgroups of children, and Head Start centers. It finds that past estimates of the average effect of Head Start programs mask a wide range of relative program effectiveness.
Design Options for an Evaluation of Head Start Coaching
Using a study of coaching in Head Start as an example, this report reviews potential experimental design options that get inside the “black box” of social interventions by estimating the effects of individual components. It concludes that factorial designs are usually most appropriate.
This report provides recommendations for an evaluation of coaching that may impact teacher and classroom practices in Head Start and other early childhood settings — including about the research questions; the design of the impact study, implementation research, and cost analysis; and logistical challenges for carrying out the design.
This paper provides practical guidance for researchers who are designing studies that randomize groups to measure the impacts of educational interventions.
This MDRC working paper on research methodology provides practical guidance for researchers who are designing studies that randomize groups to measure the impacts of interventions on children.
