Summer is a critical time for students with or at-risk for reading difficulties. This study examines the added benefit of a one-on-one intensive reading intervention presented during a school-based summer literacy program targeting first through fifth-grade students' foundational reading skills. The individually administered, UFLI-Intensive…

The purpose of this study was to examine the impact of supplemental word recognition strategies on students receiving intensive (Tier III) remedial reading instruction. Two-hundred and thirteen middle school students with reading difficulties received an intensive reading intervention (i.e., Corrective Reading Decoding strand) delivered by trained…

This district had a consistent curriculum and access to decodable books, however treatment students received the…

This study examined the effectiveness of the intensive implementation of a multicomponent reading intervention ("Voyager Passport") with 306 fourth-grade students with severe reading difficulties. Students with reading comprehension achievement below the 15th percentile in the fall of fourth grade were randomly assigned to the intensive…

Despite the emerging evidence base on response to intervention, there is limited research regarding how to effectively use progress-monitoring data to adjust instruction for students in Tier 2 intervention. In this study, we analyzed extant data from a series of randomized experimental studies of a kindergarten supplemental reading intervention to…

The purpose of this varied replication study was to evaluate the effects of a supplemental reading intervention on the beginning reading performance of kindergarten students in a different geographical location and in a different instructional context from the initial randomized trial. A second purpose was to investigate whether students who…
