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…

We investigated whether individual differences in overall receptive vocabulary knowledge measured at the beginning of the year moderated the effects of a kindergarten vocabulary intervention that supplemented classroom vocabulary instruction. We also examined whether moderation would offset the benefits of providing Tier-2 vocabulary intervention…

Upper elementary school students who have reading problems may have difficulty in one or more areas of reading, each requiring specific types of interventions. This study evaluated a short-term reading intervention for 46 fifth-grade students with poor reading comprehension. Students were randomly assigned to an intervention or no treatment…

Presently there is no consensus on the specific behavioral treatment of choice for targeting language in young nonverbal children with autism. This randomized clinical trial compared the effectiveness of a verbally-based intervention, Pivotal Response Training (PRT) to a pictorially-based behavioral intervention, the Picture Exchange Communication…

The focus of the present study was enhancing word problem and calculation achievement in ways that support prealgebraic thinking among second-grade students at risk for mathematics difficulty. Intervention relied on a multitier support system (i.e., responsiveness to intervention, or RTI) in which at-risk students participate in general classroom…

This randomized control trial examined the efficacy of a multitiered supplemental tutoring program within a first-grade responsiveness-to-intervention prevention model. Struggling first-grade readers (n = 649) were screened and progress monitored at the start of the school year. Those identified as unresponsive to general education Tier 1 (n =…

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, &…

We explore the potential of a computer-adaptive decoding game in Spanish to increase the decoding skills and oral reading fluency in Spanish and English of bilingual students. Participants were 78 first-grade Spanish-speaking students attending bilingual programs in five classrooms in Texas. Classrooms were randomly assigned to the treatment…

The response-to-intervention model is predicated upon increasingly intensive tiers of instruction. The aim of the present study was to examine the efficacy of a Tier-2 small-group literacy intervention ("MiniLit") designed for young readers who are still struggling after experiencing whole-class initial instruction. A total of 22…

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 study compared the effects of Tier 2 reading interventions that operated in response-to-intervention contexts. Kindergarten children (N = 90) who were identified as at risk for reading difficulties were stratified by school and randomly assigned to receive (a) Early Reading Intervention (ERI; Pearson/Scott Foresman, 2004) modified in response…

The purpose of this quantitative study was to investigate the effectiveness of a system-wide Response to Intervention (RTI) program on the mathematical achievement of seventh and eighth grade students. The study consisted of five district schools with a total of 502 participants. The students were identified as belonging to one of two tiers, which…
