These are the appendices for the report "The Effects of an Academic Language Program on Student Reading Outcomes." This study investigated WordGen Elementary, a program designed to improve fourth- and fifth-grade students' ability to understand and communicate academic language and their general reading skill. The program provider…

IES is the primary research, evaluation, and statistics arm of the U.S. Department of Education. Established through the Education Sciences Reform Act of 2002 (ESRA), the Institute's mission is to expand fundamental knowledge and understanding of education and to provide education leaders and practitioners, parents and students, researchers, and…

The Big Lift is a collective impact initiative extending from preschool to third grade in San Mateo County, California. The collective impact effort consists of people and organizations from various sectors uniting to tackle a single, complicated societal problem -- in this case, third grade reading achievement. The initiative is a partnership of…

Providing academic assistance to English Language Learners (ELLs) is varied and often ineffective. The purpose of this causal-comparative study was to determine if there was a relationship between 9th grade students' performance on the High School Graduation Exam (HSGE) in reading and language and the Push-in and Pull-out models of instruction.…

In 2009, some Spanish regions implemented the Program School 2.0 with the purpose of introducing digital methodologies at schools. The aim of this paper is to analyse which part of the variation in reading scores is due to this program. For this purpose, we use data from the Program for International Student Assessment (PISA 2009 and 2012) for…

In critiquing our paper on "The literacy performance of ex-Reading Recovery students between two and four years following participation in the program: Is this intervention effective for students with early reading difficulties?", Schwartz argues that we have engaged in pursuing political and ideological agendas as part of our ongoing…

Evaluators report effects of education initiatives as standardized effect sizes, a scale that has merits but obscures interpretation of the effects' practical importance. Consequently, educators and policymakers seek more readily interpretable translations of evaluation results. One popular metric is the number of years of learning necessary to…

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,…

Data-based instructional programs have proliferated in American schools despite limited evidence of their effectiveness in improving educator practice and raising student achievement. We report results from a two-year school-randomized evaluation of the Achievement Network (ANet), a program providing schools with standards-aligned interim…

Research indicates that the practice of grade-level retention may have negative effects on students; nevertheless it is often used in practice for students who fail to meet academic standards. In contrast to retention, response to intervention (RtI) is a sound practice that is based on a preventive framework and utilizes differentiated instruction…

Educators and policymakers have been concerned about the problem of early literacy performance for many decades. Despite educational reform to increase standards, many children consistently fail to read at levels that enable them to compete globally. The purpose of this study was to provide a data driven program evaluation of a reading…

The 4Rs Program (Reading, Writing, Respect and Resolution) is a "dual focus" whole school universal intervention designed to promote literacy development and social-emotional learning, that is currently being rigorously evaluated using a school-randomized trial of 18 elementary schools (9 intervention, 9 control) in New York City. The…

Class-size reduction (CSR) mandates presuppose that resources provided to reduce class size will have a larger impact on student outcomes than resources that districts can spend as they see fit. I estimate the impact of Florida's statewide CSR policy by comparing the deviations from prior achievement trends in districts that were required to…

When attempting to determine if an intervention has a causal impact, the "gold standard" of program evaluation is the randomized controlled trial (RCT). In education studies random assignment is rarely feasible at the student level, making RCTs harder to conduct. School-level assignment is more common but this often requires considerable resources…

Early identification and intervention for students at risk for reading failure is essential to establish the foundational skills necessary for students to become skilled readers. The focus on evidence-based practices and data-driven decision making leads educators to consider additional instructional approaches, such as formative assessment (FA)…
