The important role of reading fluency in the comprehension and motivation of readers is well documented. Two reading rate intervention programs were compared in a cluster-randomized clinical trial of students who were considered at-risk for reading failure. One program focused instruction at the word level; the second program focused instruction…

Literacy instruction for students with significant intellectual disabilities traditionally emphasizes isolated skills instruction focusing on sight words and basic vocabulary. Recent research suggests these students benefit from high-quality instruction that includes comprehension and storybook reading. This study examined the effect of a…

This study investigated the effectiveness of "Math Explorer" at enhancing the word problem-solving skills of students with mathematics difficulties (MD). The study, which had a multiple-probe-across-subjects design, was conducted over 18 weeks. Four students with MD in Grades 2 and 3 participated. All students were able to use the four-step…

Fluent oral reading is an essential literacy skill, and data suggest that it is a consistent and persistent problem for many elementary school children. Peer-mediated instruction in which students work together to support each other is an evidence-based practice for improving performance in a variety of academic areas. In this study, we…

Patterns of identification for special education services across three cohorts of students in kindergarten through third grade before and after implementation of a schoolwide, three-tier reading prevention model in one large school district are reported. The first cohort of students represents a historical control group that did not participate in…

This study sought to examine the effects of Tier 2 intervention in a multitiered model on the performance of first- and second-grade students who were identified as having mathematics difficulties. A regression discontinuity design was utilized. Participants included 126 (Tier 2, n = 26) first graders and 140 (Tier 2, n = 25) second graders. Tier…

The purpose of this study was to evaluate the effectiveness of supplemental reading instruction on the reading performance of four (two boys, two girls) second graders who were English learners (ELs) and poor readers through the use of a multiple probe across-participants design. All students received instruction from a commercial reading program,…

This study explored two aspects of expanding the use of research-based practices in schools: (a) the extent to which mentor teachers could effectively teach a fellow teacher an instructional practice they had learned the previous year and (b) the extent to which the target practice would be implemented effectively by the partner after instruction…
