This study examined the effects of a small group intervention targeting paraphrasing and text structure instruction on the main idea generation and reading comprehension of students with reading disabilities in Grades 4 and 5. Students (N = 62) were randomly assigned to receive the Tier 2-type intervention or business-as-usual instruction.…

We examine the efficacy of an intervention to improve word reading and reading comprehension in fourth- and fifth-grade students with significant reading problems. Using a randomized control trial design, we compare the fourth- and fifth-grade reading outcomes of students with severe reading difficulties who were provided a researcher-developed…

This randomized control trial examined the efficacy of an intervention aimed at improving multisyllabic word reading (MWR) skills among fourth- and fifth-grade struggling readers (n = 109, 48.6% male), as well as the relative effects of an embedded motivational beliefs training component. This study was a closely aligned replication of our earlier…

Most U.S. classrooms serve students with various linguistic and academic needs. Tier-I universal approaches support English language learners (ELLs) without segregating them into a different track and thereby constraining future learning opportunities. The current study examines whether Word Generation (WG), a Tier-I discussion-based program…

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…

Small-group, text-based discussions are a prominent and effective instructional practice, but the literature on the effects of different group composition methods (i.e., homogeneous vs. heterogeneous ability grouping) has been inconclusive with few direct comparisons of the two grouping methods. A yearlong classroom-based intervention was…

A multi-cohort cluster randomized trial was conducted to estimate effects of rich vocabulary classroom instruction on vocabulary and reading comprehension. A total of 1,232 fourth- and fifth-grade students from 61 classrooms in 24 schools completed the study. Students received instruction in 140 Tier Two vocabulary words featured in two…

In the study, we investigated effects of 2 different versions of a web-based tutoring system to provide 5th-grade students with strategy instruction about text structure, which was an intervention to improve reading comprehension. The design feature assessed varied in individualization of instruction (individualized or standard). The more…

Collaborative Strategic Reading (CSR) is a set of instructional strategies designed to improve the reading comprehension of students with diverse abilities (Klingner and Vaughn 1996). Teachers implement CSR at the classroom level using scaffolded instruction to guide students in the independent use of four comprehension strategies; students apply…

The authors describe an independent evaluation of the READ 180 Enterprise intervention designed by Scholastic, Inc. Despite widespread use of the program with upper elementary through high school students, there is limited empirical evidence to support its effectiveness. In this randomized controlled trial involving 312 students enrolled in an…

This study examined the effectiveness of a yearlong, researcher-provided, Tier 2 (secondary) intervention with a group of sixth-graders. The intervention emphasized word recognition, vocabulary, fluency, and comprehension. Participants scored below a proficiency level on their state accountability test and were compared to a similar group of…

The purpose of this evaluation of Scholastic's "System 44" conducted by RMC Research was to expand the existing research on students with learning disabilities by conducting a randomized study of struggling readers with approximately half of the sample comprised of students with learning disabilities. Specifically, this evaluation…

Scholastic's "System 44" is a foundational reading program intended for older struggling readers who have not mastered basic phonics and decoding skills. Combining researched-based phonics instruction with adaptive technology, "System 44" is designed to improve students' word reading accuracy, fluency, and comprehension. The…

This document reports on the impacts on student achievement for four supplemental reading curricula that use similar overlapping instructional strategies designed to improve reading comprehension in social studies and science text. Fifth-grade reading comprehension for each of three commercially-available curricula (Project CRISS, ReadAbout, and…

Gaps in reading performance between Anglo and Latino children are associated with gaps in vocabulary knowledge. An intervention was designed to enhance fifth graders' academic vocabulary. The meanings of academically useful words were taught together with strategies for using information from context, from morphology, from knowledge about multiple…
