A formative pilot study of a fractions intervention was conducted to address the intervention's potential for improving fifth-grade struggling students' knowledge of fractions, and to identify any logistical or instructional design issues, before scaling up for a randomized control trial. In the first section, we provide details of the formative…

This study assesses the long-term linguistic and academic outcomes associated with different bilingual language education models for low-income dual language learners (DLLs) residing in a bilingual, bicultural context. As part of the Miami School Readiness Project (MSRP), we analyzed the impact of program model on gains in English language…

Educator performance evaluation systems are a potential tool for improving student achievement by increasing the effectiveness of the educator workforce. For example, recent research suggests that giving more frequent, specific feedback on classroom practice may lead to improvements in teacher performance and student achievement. This report is…

Response to intervention (RTI) has received considerable attention from both researchers and practitioners as a schoolwide model for service delivery. However, research is limited on RTI applications in middle and high schools. The purpose of this article is to describe the outcomes of an experimental examination of a secondary (Tier 2) literacy…

The study authors examined the impact of "Responsive Classroom," a professional development program for teachers, on student achievement. This study took place in a large, ethnically and socioeconomically diverse district in a mid-Atlantic state. The intervention was implemented during 3 school years from 2008 to 2011. Study authors…

In this experimental study, 20 multiple-choice test items from the Massachusetts Grade 5 science test were linguistically simplified, and original and simplified test items were administered to 310 English learners (ELs) and 1,580 non-ELs in four Massachusetts school districts. This study tested the hypothesis that specific linguistic features of…

Previous studies about ELs have reported data on active English Learners--defined as those students who have not yet reached proficiency on a state English test--at a specific moment in time. This study, for the first time, analyzed the long-term trajectories of 18,000 CPS students who began kindergarten as ELs and followed their progress all the…

This study followed a cohort of students from Grade 1 to Grade 11 in one struggling school district that had Reading Recovery (RR) in the Grade 1. The RR program is an intervention given only to students in the Grade 1 who are reading below grade level on the Gates-MacGinitie Reading Assessment. The researched district had a high poverty, high…

This study evaluates the impacts and costs of the Reading Partners program, which uses community volunteers to provide one-on-one tutoring to struggling readers in under-resourced elementary schools. The evaluation uses an experimental design. Students were randomly assigned within 19 different Reading Partners sites to a program or control…

Efforts to support children in schools require addressing not only academic issues, but also out-of-school factors that can affect students' ability to succeed. This study examined academic achievement of students participating in City Connects, a student support intervention operating in high-poverty elementary schools. The sample included 7,948…

The ability to read aloud fluently is a reflection of one's ability to automatically decode words and comprehend text at the same time (Samuels, 2006), a task which may be difficult for many intermediate elementary students with learning disabilities (LD) (Ferrara, 2005). Previous research shows that audio-assisted repeated readings and…

The authors conducted a quasi-experimental investigation of effects on achievement by grade-level teams focused on improving learning. For 2 years (Phase 1), principals-only training was provided. During the final 3 years (Phase 2), school-based training was provided for principals and teacher leaders on stabilizing team settings and using…
