This experimental study examined the efficacy of a multicomponent reading intervention compared to a business-as-usual comparison condition on the reading comprehension and content area vocabulary outcomes of adolescent students with low reading comprehension. We randomly assigned 9th-grade students with low reading comprehension to a…

This study evaluated the efficacy of the Word Learning Strategies (WLS) supplementary program designed to develop upper-elementary students' vocabulary skills in order to improve reading comprehension. The study used a true, group-randomized, experimental design, which randomly assigned 46 4th grade classrooms (n=1324 students) from 12 districts…

This study aimed to determine the efficacy of a content knowledge and reading comprehension treatment implemented by 8th-grade social studies teachers over the course of 1 school year. We randomly assigned 8th-grade students with reading difficulties to the intervention treatment condition (n = 45) or the business-as-usual comparison condition…

This experimental study examined the effectiveness of a text-based reading and vocabulary intervention with self-regulatory supports for 4th graders with low reading comprehension. Students with standard scores on the Gates MacGinitie Reading Test between 1.0 standard deviation (SD) and 0.5 SD below the normative sample were included (N=44) and…

A 2-year, randomized control trial with 9th to 10th grade students with significant reading problems was provided for 50 minutes a day in small groups. Comparison students were provided an elective class and treatment students the reading intervention. Students were identified as demonstrating reading difficulties through failure on their state…

The purpose of this study was to examine the relationship of two implementation variables (source of technical support and time of implementation) to first grade reading achievement across three naturally-occurring conditions over a six-year time span. Two of the conditions involved implementation of Direct Instruction (DI) curriculum programs,…

We conducted a randomized field trial to test an academic vocabulary intervention designed to bolster the language and literacy skills of linguistically diverse sixth-grade students (N = 2,082; n = 1,469 from a home where English is not the primary language), many demonstrating low achievement, enrolled in 14 urban middle schools. The 20-week…

This study investigated the effect of a large group narrative intervention on diverse preschoolers' narrative language skills with aims to explore questions of treatment efficacy and differential response to intervention. A quasi-experimental, pretest/posttest comparison group research design was employed with 71 preschool children. Classrooms…

Despite advances in the science of teaching reading, there still exists a small percentage of students who fail to make the expected progress in reading-related skills, notwithstanding attempts at intervention. Even if these struggling readers learn to decode adequately, fluency remains a problem for many, and little is known about the…

Students entering high school face many new academic challenges. One of the most important is their ability to read and understand more complex text in literature, mathematics, science, and social studies courses as they navigate through a rigorous high school curriculum. The Regional Educational Laboratory (REL) Northwest conducted a study to…

The goal of this study was to test the effectiveness of WestEd's Reading Apprenticeship (RA) professional development program on teacher practices and student learning.

This report presents findings from the Enhanced Reading Opportunities (ERO) study, a demonstration and evaluation of two supplemental literacy programs that aim to improve the reading comprehension skills and school performance of struggling ninth-grade readers. The report, which is the second of three, focuses on the second of two cohorts of…

To evaluate the effects of an intensive tertiary reading intervention, 27 students with severe reading difficulties and disabilities, 14 of whom had demonstrated an inadequate response to 1-2 tiers of prior reading instruction, received a 16-week intervention package involving decoding and fluency skills. The decoding intervention was provided for…
