Background/Context: Observational studies often employ regression discontinuity (RD) designs and multiple control-group designs to explore the causal quantities of interest. RD designs assess policy and program effectiveness by assigning subjects to treatment based on whether they exceed a pre-defined cutoff. RD designs are classified into two…

Background/Context: Some observational studies involve multiple layers of treatment selection, specifically in the context of the extended time accommodation (ETA) for English language learners (ELLs). In ETA settings, the first selection occurs due to the eligibility rule, where students whose ELL English proficiency is below a certain threshold…

We study the impact of post-1990 school finance reforms, during the so-called "adequacy" era, on absolute and relative spending and achievement in low-income school districts. Using an event study research design that exploits the apparent randomness of reform timing, we show that reforms lead to sharp, immediate, and sustained increases…

The authors evaluated the effects of P-SELL, a science curricular and professional development intervention for fifth-grade students with a focus on English language learners (ELLs). Using a randomized controlled trial design with 33 treatment and 33 control schools across three school districts in one state, we found significant and meaningfully…

This study examines the efficacy and moderators of New York State interventions for schools in need of improvement under NCLB, including: (1) school transfer, (2) supplementary education service (3) corrective action, (4) planning for restructuring, and (5) restructuring. Despite the fact that schools in increasingly aggressive treatment groups…

Success for All (SFA), one of the best-known school reform models, aims to improve the reading skills of all children but is especially directed at schools that serve large numbers of students from low-income families. First implemented in 1987, SFA combines a challenging reading program, whole-school reform elements, and an emphasis on continuous…

Learning to read by the end of third grade is the gateway to lifelong success. When students are not able to read by the end of third grade, their risk of falling behind grows exponentially. In fact, research shows that nine out of ten high school dropouts were struggling readers in third grade. Students reading below grade level are almost six…

Despite the potential of differentiated curricula to enhance learning, limited research exists that documents their impact on Grade 3 students of all ability levels. To determine if there was a difference in achievement between students involved in 16 weeks of predifferentiated, enriched mathematics curricula and students using their district's…

We use three data sources to build a rationale for why intensive interventions are necessary for students with pervasive reading disabilities: current data on the performance of students with disabilities on reading achievement measures over time, observation studies on students with reading disabilities in general and special education…

Recent research on statewide voucher programs in Louisiana and Indiana has found that public school students that received vouchers to attend private schools subsequently scored lower on reading and math tests compared to similar students that remained in public schools. The magnitudes of the negative impacts were large. A case to use taxpayer…

The Afterschool Alliance, in partnership with Dollar General Literacy Foundation, is proud to present this issue brief examining the vital role afterschool programs play in building students' literacy skills. This issue brief will focus on the year-round support needed to help students with their reading, writing and critical thinking skills. This…

Research and history has demonstrated the overwhelming disparity and gap of mathematical achievement between African Americans and their White counterparts. According to the National Assessment of Educational Progress (NAEP), the achievement gap on a national level is prevalent. The USA jurisdiction has Black 8th grade math students results at 12%…

The Focused Practice Instructional Approach (FPIA) was based on the Environmental Mode of instruction established by George Hillocks' 1986 meta-analysis for writing instruction. The purpose of this study was to clearly define the FPIA approach using the original studies and test if it was significantly effective in fourth grade classrooms using…

Rigorous research provides information that will allow other schools and districts to select interventions that have a scientifically based track record of effectiveness. All Striving Reader grants include the mandate to evaluate literacy intervention(s) targeted to adolescents who are reading significantly below grade level. Although all studies…
