We examined the efficacy of a Technology-Based Early Language Comprehension Intervention (TeLCI) designed to teach inferencing in a non-reading context. A group of Grades 1 and 2 students from 2 elementary schools in the U.S. Midwest identified as at risk of comprehension difficulties were assigned randomly to a business-as-usual control group or…

Group size and treatment intensity are understudied topics in mathematics intervention research. This study examined whether the treatment intensity and overall intervention effects of an empirically validated Tier 2 mathematics intervention varied between intervention groups with 2:1 and 5:1 student-teacher ratios. Student practice opportunities…

Teachers' implementation of differentiated supplemental instruction is critical to help students with or at risk for reading-related disabilities acquire early reading and vocabulary skills. This study represents an initial investigation of whether classroom teachers' intervention fidelity (exposure, adherence, and quality) of targeted reading…

In this study, we tested the outcomes of access to a response to intervention (RtI) model in kindergarten or in first grade on end-of-Grade-2 reading achievement and placement in special education. Across five schools, 214 students who began having access to Tier 2 intervention in kindergarten or first grade were compared in Grades 1 and 2 with…

This study, framed by the component model of reading (CMR), examined the relative importance of kindergarten-entry predictors of first grade reading performance. Specifically, elements within the ecological domain included dialect, maternal education, amount of preschool, and home literacy; elements within the psychological domain included…

In this study, response to intervention and stability of reading performance of 41 kindergarten children identified as at risk of reading difficulty were evaluated from kindergarten through third grade. All students were assessed in the fall of each academic year to evaluate need for intervention, and students who fell below the 30th percentile on…

Two studies examined response to varying amounts of time in reading intervention for two cohorts of first-grade students demonstrating low levels of reading after previous intervention. Students were assigned to one of three groups that received (a) a single dose of intervention, (b) a double dose of intervention, or (c) no intervention.…

In this quasi-experimental study, which is part of a series of investigations on supplemental reading tutoring variations, the relative effectiveness of more intense decoding instruction or text reading practice was examined. Fifty-seven first-grade students scoring in the lowest quartile for reading skills received either classroom reading…

Several multiple-probe-across-participants design studies were employed to evaluate the effectiveness of a supplemental tutoring intervention using "Read Well" (Sprick, Howard, and Fidanque, 1998-2000). In Year 1, we conducted two studies with 7 first-, second-, and third grade children (1 girl and 6 boys), who were classified as having…
