This study of 952 fifth and sixth graders in Washington, DC, and Alexandria, Virginia, found that students who were offered the "Higher Achievement" program had higher test scores in mathematical problem solving and were more likely to be admitted to and attend private competitive high schools. "Higher Achievement" is a…

This study used a randomized controlled trial design to investigate the ROOTS curriculum, a 50-lesson kindergarten mathematics intervention. Ten ROOTS-eligible students per classroom (n = 60) were randomly assigned to one of three conditions: a ROOTS five-student group, a ROOTS two-student group, and a no-treatment control group. Two primary…

This study examined the role of initial skill in moderating intervention effects of a 50 lesson mathematics intervention program, ROOTS, for at risk kindergarten students focused on developing whole number concepts and skills. The study utilized a randomized block design with at-risk students (n = 592) within classrooms (n = 60) randomly assigned…

The purpose of this longitudinal study is to investigate whether an early childhood intervention using an explicit and transparent number naming system will have a lasting benefit to English and Spanish speaking children in their mathematics achievement related to number sense by accelerating their acquisition of concepts of numeracy and place…

In the context of an experimental trial, the authors examined variability in treatment and control teachers' use of several "Responsive Classroom" (RC) practices to predict students' 4th grade academic achievement. Further, they examined the extent to which use of the "RC" practices is differentially important for subgroups of…

This pilot study examined the efficacy of a Tier 2 first-grade mathematics intervention program targeting whole-number understanding for students at risk in mathematics. The study used a randomized block design. Students (N = 89) were randomly assigned to treatment (Fusion) or control (standard district practice) conditions. Measures of…

My Virtual Reading Coach (MVRC) is an online program for students who have been identified as struggling readers. It is used as an intervention within the Response to Intervention (RtI) framework, as well as for students with disabilities. The software addresses reading sub-skills (i.e., comprehension, fluency, phonemic awareness, phonics, and…

The State Compensatory Education (SCE) program is designed to reduce dropout rates and increase academic performance of students identified as being at-risk of dropping out of school. SCE operates as a funding source to supplement instructional services and offer academic support to students who meet the SCE at-risk criteria established by the…

Multitiered systems of reading instruction and intervention, including response to intervention, are widely used in early reading by schools to provide more intense services to students who need them. Research using randomized controlled trials has compared innovative Tier 2 interventions to business-as-usual Tier 2 approaches and established a…

This study examined the efficacy of a kindergarten mathematics intervention program, ROOTS, focused on developing whole-number understanding in the areas of counting and cardinality and operations and algebraic thinking for students at risk in mathematics. The study utilized a randomized block design with students within classrooms randomly…

This paper presents findings of an efficacy trial examining the effect of a multi-tiered instruction and intervention model on first grade, at risk students' reading outcomes. Schools (n = 16) were randomly assigned to the treatment or control condition. In the fall of Grade 1, students were assigned to an instructional tier on the basis of SAT-10…

"READ 180" is a reading program designed for students in elementary through high school whose reading achievement is below the proficient level. The goal of "READ 180" is to address gaps in students' skills through the use of a computer program, literature, and direct instruction in reading skills. The software component of the…
