Background: Early-grade reading proficiency is well documented as in important factor for later academic success. Researchers and educators consider the achievement of reading proficiency by the end of grade three to be crucial to future academic success and financial independence (Hein et al., 2013; La Paro & Pianta, 2000; Singh, 2013). As…

Educators and researchers have been fighting the reading wars for the last century, with battles see-sawing literacy instruction in American schools from phonics to whole language and, most recently, back to phonics again. Over the last decade, 32 states and the District of Columbia have adopted new "science of reading" laws that require…

Children should develop literacy skills that progress from learning to read to reading to learn as they move from kindergarten through early elementary. These skills support reading proficiency and build knowledge in all subject areas. Students who struggle with literacy skills as early as kindergarten often continue to read below grade level…

There is little empirical research regarding the impact the four-day per week school schedule has on primary grade student achievement. Early literacy and numeracy skills are essential functions that provide the basis for success in the American public education system and a global economy. Any school schedule that adversely affects mastery of…

This Policy Guide draws on work with five states to provide context and guidance for policymakers looking to strengthen the pre-K to K-3 continuum and create opportunities to close the achievement gap. It includes a tear-out page of guiding questions at the end.

The purpose of this paper is to showcase new research that seeks to provide guidance on the heterogeneity of treatment effects by utilizing the variance of demographic differences in state assessments. This study is focused on a simple randomized block design where students are nested within schools, and within each school students are randomized…

The fights currently raging under the banner of "education reform" are nothing compared to those battles fought on the fronts of the "Reading Wars." For decades now, educators, policymakers, parents, and communities have battled fiercely over how best to teach reading--phonics, whole language, or scientifically based reading.…

Despite the prevalence of charter schools in the United States, few experimental studies evaluate the impact of charter school attendance on students in the early elementary grades. Using data from a randomized lottery in which kindergarten students and their parents applied to two oversubscribed and well-established charter schools in Denver,…

Randomized experiments are often considered the strongest designs to study the impact of educational interventions. Perhaps the most prevalent class of designs used in large scale education experiments is the cluster randomized design in which entire schools are assigned to treatments. In cluster randomized trials (CRTs) that assign schools to…

Data systems that use monolingual language frameworks to understand the reading achievement of third-grade students provide inadequate information about emerging bilingual (EB) learners. The authors of this research study apply two competing ideologies (parallel monolingualism and holistic bilingualism) to interpret one set of data. Their findings…

Background: Cluster-randomized experiments that assign intact groups such as schools or school districts to treatment conditions are increasingly common in educational research. Such experiments are inherently multilevel designs whose sensitivity (statistical power and precision of estimates) depends on the variance decomposition across levels.…

The study uses a quasi-experimental comparison group design to test the effectiveness of "Treasures" by comparing outcomes for students who used "Treasures" to those who did not use "Treasures", adjusting for differences between the "Treasures" and comparison groups on baseline characteristics. The study…

Based on the findings of a recent three-year study by Dominican University's Graduate School of Library and Information Studies, the authors can confirm what many librarians have long suspected: students who take part in their local library's summer reading program significantly improve their reading skills. This article describes the results of…

With decreasing enrollment, decreasing funding for public school education, changes in family and societal needs, and the mandates of the No Child Left Behind Act, policymakers and school leaders are wrestling with reforms to the school calendar and instructional time spent in the classroom, with the goal of increasing student achievement.…

This report describes student performance in third grade Reading Comprehension and fourth grade Reading and Writing from the spring 1998 administration of the Colorado Student Assessment Program (CSAP). In this second administration of CSAP, all third and fourth grade students in Colorado were accounted for. The report provides policymakers,…
