This paper provides practical guidance for researchers who are designing studies that randomize groups to measure the impacts of educational interventions.
A Research Note for Funders
Targeted toward very low-income families in six high-poverty New York City communities, Family Rewards offers cash payments tied to efforts and achievements in children’s education, family preventive health care practices, and parents’ employment. This paper reviews data on participants’ receipt of rewards and offers preliminary estimates of the program’s impacts on selected educational outcomes during the first year.
What We Know, What We Don’t, and What’s Next
Studies of Reading First released in 2008 found no overall effect on student reading comprehension, and the program was eliminated in 2009. However, the research findings were more nuanced than was widely reported, and they offer lessons for policymakers making critical choices today about how the federal government can best support the teaching of reading to young children.
No universal guideline exists for judging the practical importance of a standardized effect size, a measure of the magnitude of an intervention’s effects. This working paper argues that effect sizes should be interpreted using empirical benchmarks — and presents three types in the context of education research.
Empirical Guidance for Studies That Randomize Schools to Measure the Impacts of Educational Interventions
This paper examines how controlling statistically for baseline covariates (especially pretests) improves the precision of studies that randomize schools to measure the impacts of educational interventions on student achievement.
Findings from the Extended-Service Schools Initiative
Launched in 1997, the Extended-Service Schools (ESS) Initiative helped establish after-school programs in 17 communities across the country, each of which adapted one of four program models to local circumstances and needs.
