This study examines the impacts of two AmeriCorps programs, Minnesota Reading Corps and Wisconsin Reading Corps, where AmeriCorps volunteers provide literacy tutoring to at-risk kindergarten through third-grade (K-3) students utilizing a response-to-intervention framework. This evaluation replicates a prior randomized controlled trial evaluation…

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…

The present study used a randomized control trial to examine the effects of a widely-used multi-component Tier 2 type intervention, Passport to Literacy, on the reading ability of 221 fourth graders who initially scored at or below the 30th percentile in reading comprehension. Intervention was provided by research staff to groups of 4-7 students…

The purpose of this study was to test the promise of the NumberShire Level 1 Gaming Intervention (NS1) to accelerate math learning for first-grade students with or at risk for math difficulties. The NS1 intervention was developed through the Institute of Education Sciences, Small Business Innovation Research Program (Gause, Fien, Baker, &…

This ex post facto descriptive-comparative quantitative study compared the differences in reading achievement between groups of 6th- through 8th-grade students enrolled in a response to intervention (RtI) classroom against groups of students enrolled in a general education classroom. Students across English language learner and low socioeconomic…

This research investigated the immediate and long-term effects of a Tier 2 intervention for beginning readers identified as having a high probability of reading failure using a randomized control trial. First-grade participants (n = 123) were randomly assigned either to a 25-session intervention targeting key reading components, including…

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…

This article describes a randomized controlled trial conducted to evaluate the effects of an intensive, individualized, Tier 3 reading intervention for second grade students who had previously experienced inadequate response to quality first grade classroom reading instruction (Tier 1) and supplemental small-group intervention (Tier 2). Also…

This study examined the efficacy of a core kindergarten mathematics program, ELM, a 120-lesson comprehensive curriculum providing instruction in (a) number operations, (b) geometry, (c) measurement, and (d) vocabulary. ELM is designed to address the learning needs of all students, including at-risk students in the general education or Tier I…
